Lapho i-Check valve efanelekile.

Inhloso yokusebenzisa i-valve yesheke ukuvikela ukugeleza okubuyiselwe okuphakathi nendawo, futhi i-valve yesheke ivame ukufakwa endaweni ephumayo yepompo. Ngaphezu kwalokho, i-valve yesheke kufanele futhi ifakwe endaweni ephumayo ye-compressor. Ngamafuphi, ukuze uvikele ukuhamba okubuyiselwe okuphakathi nendawo, kufanele kufakwe i-Check Valve emishini, kudivayisi noma ngepayipi.

Ngokuvamile, ama-valve aphezulu okuphakamisa ama-mpo asetshenziswa kumapayipi avundlile anobubanzi obungama-50mm. I-Valve eqondile ye-Lift I-valve engezansi ivame ukufakwa kuphela kwipayipi elithe mpo lwe-inlet yepumpu, kanye nokugeleza okuphakathi kusuka phansi kuya phezulu.

I-Swing Check valve ingenziwa ngengcindezi ephezulu kakhulu yokusebenza, i-PN ingafinyelela ku-42mpa, futhi i-DN nayo ingenziwa inkulu kakhulu, inani elikhulu lingafinyelela ngaphezu kwe-2000mm. Ngokuya ngezinto ezahlukahlukene zegobolondo nophawu, lungasetshenziswa kunoma yiluphi oluphakathi nendawo nanoma yiliphi ibanga lokushisa lokushisa. I-Medium amanzi, umusi, igesi, okuphakathi nendawo, i-oyela, ukudla, umuthi, njll. Izinga lokushisa elisebenzayo laphakathi liphakathi kwe -116 ~ 800 ℃.

Isikhundla sokufaka se-Swing Check valve asikhawulelwe, kuvame ukufakwa epayipini evundlile, kepha futhi kungafakwa kwipayipi elithe mpo noma ngepayipi elithambekele.

Umcimbi osebenzayo we-Butterfly Check valve ingcindezi ephansi kanye nobubanzi obukhulu, futhi umcimbi wokufaka ulinganiselwe. Ngoba ingcindezi yokusebenza ye-Butterfly Check Valve ayikwazi ukuba phezulu kakhulu, kepha ubukhulu bendawo bungaba bukhulu kakhulu, obungafinyelela ngaphezu kwe-2000mm, kepha ingcindezi ephakeme ingaphansi kuka-6.4MPA ingaphansi kuka-6.4MPA. I-valve yokuhlola uvemvane ingenziwa ngohlobo lwe-wafer, oluvame ukufakwa phakathi kwama-flanges amabili epayipi ngesimo sokuxhumeka kwe-wafer.

Isikhundla sokufaka se-Butterfly Check valve asikhawulelwe, singafakwa epayipini elivundlile, ipayipi elimile noma ngepayipi elithambekele.

I-valve ye-diaphragm i-valve ilungele amapayipi athambekele kwisando samanzi. I-diaphragm ingasusa kahle isando samanzi esibangelwa ukugeleza okuguqukayo kwe-medium. Njengoba izinga lokushisa elisebenzayo kanye nengcindezi esebenzayo yama-valves okuhlola i-diaphragm lilinganiselwe nge-diaphragm ezibonakalayo, ngokuvamile zisetshenziswa kumapayipi aphansi okushisa kanye namaphipiti ajwayelekile okushisa, ikakhulukazi amapayipi amanzi empompo. Ngokuvamile, izinga lokushisa elisebenzayo laphakathi liphakathi kuka-20 ~ 120 ℃, futhi ingcindezi yokusebenza ingaphansi kwe-1.6mpagm, kepha i-valve yokuhlola i-valve ingafinyelela ubukhulu obukhulu, futhi i-DN ephezulu ingaba ngaphezu kwe-2000mm.

I-Vappragm Check valve isetshenziswe kabanzi eminyakeni yamuva ngenxa yokusebenza kwayo okuhle kakhulu kwamanzi, isakhiwo esilula kanye nezindleko zokukhiqiza eziphansi.

I-valve ye-BALL CHECK inokusebenza okuhle kokubekwa uphawu, ukusebenza okuthembekile nokumelana nesando samanzi ngoba uphawu luyindawo embozwe yinjoloba; Futhi ngoba uphawu lungaba ibhola elilodwa noma amabhola amaningi, kungenziwa ububanzi obukhulu. Kodwa-ke, uphawu lwalo luyindawo eyize embozwe ngerabha, engalungele amapayipi aphezulu kakhulu, kepha ilungele kuphela amapayipi aphakathi nendawo aphansi.

Njengoba impahla yegobolondo ye-ball Check valve ingenziwa ngensimbi engenasici, futhi umkhawulo we-aze ungambozwa ngopulasitiki wobunjiniyela be-PTFE, futhi ungasetshenziswa kumapayipi ajwayelekile anemidiya ejwayelekile.

Ukushisa okusebenzayo kwalolu hlobo lwe-valve ye-Check valve kuphakathi kwe--101 ~ 150 ℃, ingcindezi yokuphakama yi-≤4.0MPA, kanye nobubanzi be-Micronal Diansing buphakathi kwama-200 ~ 1200mm.
