Kev kho coupling yog dab tsi?
Kho coupling (kho clamp) - ib qho khoom siv rau kev sib khi puas tsuaj rau cov kav dej lossis cov kav dej sib txuas ua los ntawm ntau yam ntaub ntawv;Ib qho ib qho los yog sib txuas txuas txuas txuas rau sab nrauv ntawm lub raj xa dej kom kaw nws los yog kom muaj kev sib txuas ntawm ob lub kav dej, lossis txuas cov yeeb nkab rau ntau yam khoom.
Hlau, yas thiab hlau-yas kav, nrog rau cov roj hmab thiab yas hoses rau ntau lub hom phiaj thaum lub sij hawm ua hauj lwm mus sij hawm ntev raug cuam tshuam los ntawm ntau yam kev cuam tshuam tsis zoo, vim tias lawv tuaj yeem raug puas tsuaj.Nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj loj, lub raj xa dej yuav tsum tau hloov tag nrho, txawm li cas los xij, nyob rau hauv cov ntaub ntawv ntawm lub zos tsis xws luag - tawg los yog tawg, nws yog yooj yim dua thiab pheej yig dua los kho.Thiab feem ntau yuav tsum tau txuas ob lub kav dej lossis ib lub yeeb nkab nrog cov khoom sib txawv, tab sis nws tsis tuaj yeem txuas cov khoom no.Hauv txhua qhov xwm txheej no, cov cuab yeej tshwj xeeb tuaj rau kev cawm - kho couplings.
Kho couplings, nyob ntawm seb hom thiab tsim, ua ntau yam haujlwm:
● Kho cov kev puas tsuaj hauv zos rau cov kav dej - luv luv, tawg, qhov, los ntawm corrosion;
● Kev sib txuas ntawm ob lub kav dej ntawm tib lub kab los yog sib txawv;
● Kev sib txuas ntawm cov kav dej nrog cov khoom sib txuas ntxiv, fittings thiab lwm yam.
Nyob rau hauv txhua rooj plaub, yuav tsum tau siv tej yam couplings thiab auxiliary cov ntaub ntawv.Yog li ntawd, ua ntej yuav qhov zoo, koj yuav tsum nkag siab txog cov hom txuas uas twb muaj lawm, lawv cov yam ntxwv thiab cov yam ntxwv.
Hom thiab tsim kho couplings
Kev kho cov couplings ntawm kev ua lag luam tuaj yeem raug cais raws li lawv lub hom phiaj, kev ua haujlwm thiab kev siv tau, tsim thiab kev kho ntawm cov kav dej.
Raws li lub hom phiaj ntawm cov couplings yog:
● Kho - los kho qhov nruj ntawm cov yeeb nkab;
● Kev sib txuas - txhawm rau txuas ob lub kav dej lossis lub raj xa dej nrog cov khoom sib txawv;
● Universal - tuaj yeem ua haujlwm ntawm ob qho tib si kho thiab couplings.
Raws li kev siv tau, kho couplings tau muab faib ua ob peb pawg:
● Rau cov kav hlau - cam khwb cia hlau thiab hlau;
● Rau cov kav dej HDPE thiab PP ntawm txoj kab uas hla loj;
● Rau cov kav hlau-yas ntawm cov kab me me;
● Rau cov kav dej hloov tau yooj yim (hoses).
Couplings rau cov kav hlau yog ua los ntawm cov hlau cam khwb cia hlau thiab hlau (tsawg dua cov yas), rau lwm cov kav dej thiab hoses - los ntawm cov yas ntawm ntau hom (rau HDPE thiab PP - los ntawm tib lub zog qis polyethylene thiab polypropylene, rau hoses - los ntawm ntau yam nruj thiab cov yas hloov tau).
ccording rau txoj kev ntawm installation thiab tsim, kho couplings muab faib ua ob pawg loj:
● zawv zawg;
● Convoluted.
Sliding couplings yog cov khoom siv yooj yim tshaj plaws hauv kev tsim thiab siv, uas feem ntau yog tsim los rau PP thiab HDPE kav dej (kua dej, dej).Xws li ib tug coupling yog tsim nyob rau hauv daim ntawv ntawm ib tug luv luv piece ntawm cov yeeb nkab, qhov kawg ntawm uas muaj extensions (sockets) rau lub installation ntawm sealing roj hmab nplhaib.Lub coupling yog mounted rau ntawm cov yeeb nkab nrog ib tug zawv zawg - nws yog muab tso rau ntawm dawb kawg thiab txav mus rau qhov chaw ntawm kev puas tsuaj, qhov twg nws yog tsau nrog kua nplaum los yog lwm yam.zawv zawg couplings feem ntau yog siv los ua couplings rau splicing ob lub kav dej los yog txuas fittings, fittings thiab lwm yam khoom rau cov yeeb nkab tom qab lub installation ntawm tag nrho cov kav dej.

Ob-lock convoluted coupling
Convoluted couplings yog cov khoom siv ntau dua siv rau kev kho cov cam khwb cia hlau thiab steel kav ntawm ntau hom thiab txoj kab uas hla (dej thiab roj kav dej, kav dej, thiab lwm yam).Xws li cov couplings muaj ob peb qhov chaw uas tau nruab rau ntawm cov yeeb nkab thiab nruj nrog threaded fasteners (li no lub npe ntawm cov khoom no), muab ib tug nruj crimping ntawm cov yeeb nkab ntawm qhov chaw ntawm kev puas tsuaj.
Convolutional couplings, nyob rau hauv lem, muab faib ua ob hom tsim:
● Rigid compounds;
● Daim kab xev (clamps).
Rigid couplings tuaj yeem yog ob-thooj thiab peb-thooj, lawv muaj ob lossis peb ib nrab-couplings, uas txuas rau ib leeg los ntawm cov xov fasteners - ob, peb lossis ntau dua bolts nrog txiv ntseej.Feem ntau, qhov chaw ntawm ob- thiab peb-daim kho couplings yog tsim los ntawm casting los yog stamping los ntawm cam khwb cia hlau thiab hlau.Tab sis tsis ntev los no, yas couplings tsim rau cov kav dej ntawm cov kab me me tau siv ntau zuj zus.Cov khoom siv yas muaj ntau qhov kev sib txuas ntawm bolted (thaum cam khwb cia hlau couplings siv tsis pub ntau tshaj peb lub bolts rau ib qho kev sib txuas), uas sib npaug faib cov load thiab tiv thaiv kev puas tsuaj ntawm cov coupling halves.Lub coupling los nrog cov roj hmab gasket uas yog clamped ntawm cov yeeb nkab thiab cov coupling, sealing qhov txuas txuas.
Daim kab xev txuas yog ua los ntawm ib los yog ob lub plhaub taum pauv hloov tau lub plhaub (feem ntau yog cov hlau tsis muaj steel), qhov kawg uas tau muab khi ua ke nrog cov xov fasteners, tsim lub xauv.Cov couplings tuaj nrog ib thiab ob lub xauv, hauv thawj rooj plaub, tsuas yog siv ib lub plhaub daim kab xev (nrog rau ib qho ntxiv liner uas sib tshooj ntawm qhov chaw xauv), nyob rau hauv rooj plaub thib ob, ob daim kab xev, uas ua rau cov khoom zoo li ob. - ib feem rigid pob qij txha.Cov couplings no kuj siv cov roj hmab gasket.
Collet-type compression couplings rau splicing hoses thiab cov kav dej yas ntawm txoj kab uas hla me me tau muab faib rau hauv ib pab pawg.Lub hauv paus ntawm lub coupling yog ib cov ntaub ntawv yas nyob rau hauv daim ntawv ntawm ib tug luv luv piece ntawm cov yeeb nkab nrog ib tug txheej txoj kab uas hla coj mus rau lub puab txoj kab uas hla ntawm cov kav dej yuav tsum tau kev cob cog rua.Qhov kawg ntawm rooj plaub yog muab faib los ntawm kev txiav rau hauv nyias nyias petals, thiab nyob ze rau qhov chaw ntawm cov xov yog tsim.Couplings ntawm ib co configuration yog screwed mus rau lub xov, uas, ua ke nrog lub tsev petals, tsim ib tug collet clamp.Cov kav dej txuas nrog (hoses) tau nruab rau hauv lub collet, thiab thaum ntsia hlau, cov txuas txuas yog nruj nreem kaw - qhov no ua rau kev sib txuas nruj thiab muaj zog txaus yam tsis muaj kev ua haujlwm ntxiv.

Cov yam ntxwv ntawm kev kho couplings
Cov yam ntxwv tseem ceeb ntawm kev kho cov couplings suav nrog lawv qhov ntev (lossis cov kav dej hauv cheeb tsam) thiab txoj kab uas hla ntawm cov kav dej yuav tsum tau txuas nrog.Rigid convolution thiab collet couplings feem ntau yog tsim los rau cov kav dej ntawm ib txoj kab uas hla, thiab lub tes tsho convoluted ua los ntawm lub plhaub tapes tuaj yeem ntsia tau rau ntawm cov kav dej ntawm qee qhov ntawm txoj kab uas hla (feem ntau qhov no yog 5-20 hli nyob ntawm qhov loj ntawm qhov sib txuas) .Txoj kab uas hla ntawm cov couplings yog qhia nyob rau hauv millimeters, thiab rau cov kav dej thiab roj - nyob rau hauv nti.Qhov ntev ntawm cov couplings rau ntau lub hom phiaj yog nyob rau hauv thaj tsam ntawm 70-330 mm, convoluted couplings muaj standardized lengths ntawm 200 thiab 330 mm, zawv zawg couplings rau HDPE thiab PP kav - mus txog 100 mm los yog ntau tshaj, thiab collet - tsis ntau tshaj 100 mm.
Cais, nws yog ib qho tsim nyog los qhia tias muaj collet thiab zawv zawg couplings ntawm qhov sib txawv ntawm txoj kab uas hla, tsim los txuas cov kav dej sib txawv.Kho convolutions tsuas yog ntawm qhov tsis tu ncua.
Kev xaiv thiab cov yam ntxwv ntawm kev siv cov couplings kho
Thaum xaiv kev kho lossis kev sib txuas, ib tus yuav tsum coj mus rau hauv tus account hom thiab txoj kab uas hla ntawm cov kav dej yuav tsum tau txuas nrog, nrog rau qhov xwm txheej ntawm kev ua haujlwm.Qhov yooj yim tshaj plaws yog xaiv collet couplings rau hoses - nyob rau hauv xws li pipelines muaj tsawg pressures, yog li txawm ib tug yooj yim yas khoom yuav muab ib tug txhim khu kev qha kev twb kev txuas yam tsis muaj leaks.Qhov tseem ceeb ntawm no yog nrhiav kev sib txuas rau txoj kab uas hla ntawm cov hoses uas twb muaj lawm.
Rau kev kho tshiab ntawm cov kav dej phwj thiab cov kav dej raws li cov kav dej yas, zawv zawg txuas yuav tsum tau siv.Tsis tas li ntawd, txoj kab uas hla ntawm cov khoom yuav tsum tau raws nraim qhov sib txawv ntawm cov kav dej, nrog rau qhov me me los yog qhov loj me, qhov sib txuas yuav tsis poob rau hauv qhov chaw, los yog kev sib txuas yuav raug xau.Yog tias koj npaj yuav ua ib qho kev sib txuas, ces koj yuav tsum tau yuav cov kua nplaum tshwj xeeb.Yog tias koj xav tau kho cov yeeb nkab yas yam tsis muaj kev txiav nws, koj tuaj yeem siv daim kab xev convolution coupling.
Rau kev kho cov kav hlau thiab cam khwb cia hlau, nws yog ib qho tsim nyog yuav tsum siv cov couplings.Raws li twb tau hais lawm, cov khoom lag luam nruj yuav tsum raug xaiv kom raug raws li txoj kab uas hla ntawm cov kav dej, thiab qhov loj ntawm qhov hloov pauv tuaj yeem sib txawv los ntawm ob peb millimeters ntawm txoj kab uas hla ntawm cov yeeb nkab.Yog tias koj xav tau kev kho mob ceev (kub ceev), nws yog qhov zoo dua los siv cov hlua khi ib leeg, vim lawv tso cai rau koj kom tshem tawm cov xau sai sai los ntawm kev zawm ob lossis peb lub bolts.Couplings ntawm cov hom no yog muag tag nrog roj hmab foob, yog li kev yuav khoom ntawm cov khoom ntxiv yog xav tau nyob rau hauv tsawg zaus.
Kev txhim kho cov txuas txuas yog yooj yim, tab sis yuav tsum tau ua tib zoo saib xyuas txhua qhov kev ua.Cov zawv zawg coupling yog muab tso rau ntawm cov yeeb nkab thiab txav raws nws mus rau qhov chaw ntawm kev puas tsuaj, qhov twg nws yog tsau.Lub convolution coupling yog ntsia rau hauv qhov chaw: lub foob yog qhov txhab ntawm cov yeeb nkab, ib nrab couplings yog superimposed rau nws, uas yog bolted crosswise kom zoo crimping.Thaum txhim kho ib lub xauv daim kab xev txuas, nws yog ib qho tsim nyog yuav tsum tau nteg ib lub foob, muab ib co coupling rau ntawm cov yeeb nkab, thiab muab ib tug liner nyob rau hauv lub xauv qhov chaw, thiab ces nruj nreem bolts tusyees.
Nrog rau txoj kev xaiv thiab kev teeb tsa ntawm kev kho qhov sib txuas, cov kav dej yuav ua rau muaj kev ntseeg siab, tsis tas yuav tsum tau kho qhov nyuaj thiab kim rau lub sijhawm ntev.
