Classification ntawm li qub

Muaj ntau hom li qub, thiab muaj ntau txoj hauv kev faib tawm: hauv qab no yog kev qhia txog kev faib tawm los ntawm lub hom phiaj, siab, ua haujlwm kub ntawm nruab nrab, hom kev ua haujlwm, thiab kev faib tawm dav dav
(1) Classified los ntawm lub hom phiaj:
(1) Thaiv li qub: feem ntau yog siv los txiav tawm thiab ua qhov nruab nrab ntws. Hom valve no suav nrog: rooj vag valve, lub ntiaj teb valve, diaphragm valve, ntsaws valve, pob valve, npauj npaim valve, thiab lwm yam.
(2) Regulating li qub: feem ntau yog siv los tswj cov dej ntws thiab siab ntawm qhov nruab nrab, nrog rau kev tswj cov li qub, lub tshuab valve, lub siab txo qhov qub, thiab lwm yam.
(3) Kos li qub: feem ntau yog siv los tiv thaiv kev rov qab ntawm cov xov xwm, suav nrog ntau hom kev kos li qub nrog cov qauv sib txawv.
(4) Diverter valve hom: siv rau kev faib tawm, sib cais, lossis kev sib xyaw ua ke, suav nrog ntau yam kev faib tawm li qub, cov dej ntws tawm, thiab lwm yam.
(5) Kev nyab xeeb li qub: siv rau kev tiv thaiv kev ruaj ntseg overpressure, suav nrog ntau hom kev nyab xeeb li qub.
(2) Muab faib los ntawm kev siab:
(1) Tsis tshua muaj siab valve: nominal siab PN Tsawg dua los yog sib npaug rau 1.6Mpa
(2) Nruab nrab siab valve: nominal siab 1.6 Mpa ＜ PN Tsawg dua lossis sib npaug rau 6.4 Mpa
(3) Siab siab valve: nominal siab 6.4 Mpa ＜ PN Tsawg dua lossis sib npaug li 100 Mpa
(4) Ultra siab siab valve: nominal siab PN Ntau dua los yog sib npaug rau 100Mpa
(3) Muab faib los ntawm kev ua haujlwm kub ntawm qhov nruab nrab:
(1) Qhov kub thiab txias li qub: -40 degree Tsawg dua lossis sib npaug t Tsawg dua lossis sib npaug li 120 degree
(2) Nruab nrab qhov kub thiab txias: 120 degree Tsawg dua lossis sib npaug t Tsawg dua lossis sib npaug li 450 degree
(3) Siab kub valve: t Ntau dua lossis sib npaug li 450 degree
(4) Tsawg kub valve: -100 degree Tsawg dua lossis sib npaug t Tsawg dua lossis sib npaug rau -40 degree
(5) Ultra low temperature valve: t Tsawg dua lossis sib npaug rau -100 degree
(4) Muab faib los ntawm kev ua haujlwm:
Nws muab faib ua phau ntawv, pneumatic, hydraulic, hluav taws xob thiab lwm yam li qub.
(5) Kev faib tawm dav dav:
Txoj kev faib tawm no feem ntau siv tsis yog los ntawm kev ua haujlwm thiab lub hom phiaj, tab sis kuj los ntawm cov qauv. Nws feem ntau muab faib ua: rooj vag valve, lub ntiaj teb valve, throttle valve, pob valve, npauj npaim valve, diaphragm valve, ntsaws valve, kos valve, kev ruaj ntseg valve, tus kheej ua haujlwm siab tswj valve, ntws valve, thiab lwm yam.
