Compression couplings yog ib hom kev haum thiab tso cai rau koj kom sai thiab ua tau zoo ntawm lub raj xa dej tsis tas siv cov vuam lossis cov xov txuas. Kev siv hom kev sib txuas ua ke no ua rau lub siab nruj ntawm lub rooj sib txoos, thaum tuav lub peev xwm ntawm disassembling yog tias tsim nyog.

Kev npaj thiab kev tsim kho

Compression coupling suav nrog cov qauv hauv qab no:

  • collet - central lub cev threaded ntawm ob sab;
  • external ferrule ceev;
  • cua dab tshos;
  • thrust rings.

Type of couplings

Compression couplings muab faib ua:

  • Nyob ntawm cov khoom siv los ntawm cov couplings tau tsim: tooj dag, tooj liab, hlau (nrog rau txheej tiv thaiv corrosion), yas. Cov yas fittings feem ntau yog tsim los ntawm cov khoom siv tsawg-density polyethylene (HDPE). Kuj tseem muaj cov khoom siv polypropylene. HDPE coupling yog siv los ua haujlwm nrog cov yascev.
  • By configuration: ncaj thiab angled (rotary).
  • Los ntawm lub hom phiaj: txuas; kev hloov pauv (rau kev sib txuas ntawm cov kab sib txawv lossis cov kav dej sib txawv); couplings rau sanitary fittings.

kev xaiv xaiv

Thaum xaiv lub compression coupling, ua ntej ntawm tag nrho cov, lawv raug coj los ntawm cov xwm txheej ntawm nws txoj haujlwm. Yog li, cov khoom siv hlau yog siv rau cov cua sov, rau cov dej kub, nrog rau kev sib txuas lus nyob rau hauv lub teeb. Rau cov chav tsev thiab cov tshuab nyob hauv qab daus thiab hauv av, HDPE couplings yog siv, vim lawv tsis raug corrosion.

Ntxiv rau, thaum xaiv qhov sib txuas, nws yog qhov tsim nyog los xaiv cov khoom siv uas haum rau cov khoom siv ntawm cov yeeb nkab txuas. Txawm hais tias kev sib txuas ntawm cov kav dej polyethylene nrog polypropylene couplings tau txais.

Mounting Features

Kev teeb tsa cov kav dej siv hom kev sib txuas no yooj yim heev. Rau nws txoj kev siv, ntxiv rau cov kav dej yuav tsum tau txuas thiab fittings lawv tus kheej, ob lub wrenches adjustable ntawm qhov tsim nyog yuav tsum tau. Lawv qhov loj me yuav tsum sib haum rau txoj kab uas hla ntawm lub tes tsho compression.

Kev txiav txim ntawm cov txuas txuas thiab cov khoom siv:

  1. Txiav tawm qhov ntev ntawm lub workpiece, ntawm qhov kawg ntawm qhov uas ua tib zoo deburr, ob leeg sab nraud thiab sab hauv.
  2. Ntawm kawg ntawm cov yeeb nkab, muab cov ntsiab lus ntawm compression coupling hauv qab no: compression txiv ntseej, sealing nplhaib, thrust nplhaib.
  3. Muab tso rau ntawm lub collet thiab ntsia hlau rau ntawm cov txiv ntoo compression los ntawm tes. Nyob rau theem no, nws yog ib qho tseem ceeb kom paub meej tias cov txiv ntootsis warp. Nws yuav tsum clamp lub ferrule thiab o-ntiv nplhaib, tsim kom muaj kev sib txuas nruj.
  4. Siv tus ciaj ntswj kom nruj qhov kev sib txuas. Txhawm rau kom tsis txhob muaj kev puas tsuaj rau qhov haum, raws li txoj cai, nruj lub txiv ntoo nrog ib tus ciaj ntswj, thiab kho lub collet nrog lwm tus.

Cov kws tshaj lij cov kws tshaj lij tsis cuam tshuam qhov sib txuas tag nrho, tab sis tsuas yog me ntsis tshem tawm cov txiv ntoo compression, ntxig cov khoom ua haujlwm nrog qee qhov kev siv zog thiab nruj cov txiv ntoo rov qab. Vim yog lub zog siv thaum lub tshuab ua haujlwm tau teeb tsa hauv qhov sib txuas, qhov sib koom ua ke tau kaw.

Qhov zoo thiab qhov tsis zoo

Qhov zoo ntawm kev siv compression couplings piv rau welded thiab threaded kev sib txuas:

  • nrawm thiab yooj yim sib dhos ntawm cov pob caus;
  • nruj thiab kev cia siab;
  • durability - kev pabcuam lub neej tshaj 20 xyoo;
  • tsim cov kev sib txuas uas tshem tau (nrog rau txhua qhov sib dhos ntawm tib qhov kev sib txuas, tsuas yog hloov cov ntsaws ruaj ruaj);
  • ntau yam haum haum.

Qhov tsis zoo tseem ceeb uas txwv qhov kev sib txuas ntawm compression couplings yog:

  • Max haum txoj kab uas hla yog 110mm.
  • Siv hauv cov tshuab uas muaj siab tsis tshaj 1.6 MPa.
  • Rau HDPE couplings thiab polyethylene couplings, muaj qhov tsis zoo xws li tsis kam tiv thaiv hluav taws xob ultraviolet. Qhov no txwv lawv txoj kev siv nyob rau hauv qhov chaw uas lub hnub ncaj qha nkag mus. Tsis tas li ntawd, cov ntaub ntawv no muaj qhov tsis muaj cua sov.
