Kev txiav tawm valve feem ntau yog siv los txiav tawm lossis txuas qhov nruab nrab ntws.suav nrogrooj vag li qub, ntiaj teb li qub, diaphragm li qub,pob li qub, ntsaws li qub,npauj npaim li qub, plunger li qub, pob ntsaws li qub, koob-hom ntsuas li qub, thiab lwm yam.

Regulating li qub feem ntau yog siv los kho qhov ntws thiab siab ntawm qhov nruab nrab.Xws li regulating valve, throttle valve, siab txo valve, thiab lwm yam.

Kos li qub yog siv los tiv thaiv qhov nruab nrab ntawm ntws rov qab.Xws li kos li qub ntawm ntau yam qauv.

Shunt li qub yog siv los cais, faib lossis sib xyaw cov xov xwm.Nrog rau ntau yam qauv ntawm kev faib tawm li qub thiab ntxiab, thiab lwm yam.

Kev nyab xeeb li qub yog siv rau kev tiv thaiv kev nyab xeeb thaum nruab nrab yog overpressured.Xws li ntau hom kev nyab xeeb li qub.

Classified los ntawm lub ntsiab parameter

(1) Muab faib los ntawm kev siab

Lub valve uas nws ua hauj lwm siab yog qis dua tus qauv atmospheric siab.

Tsis tshua muaj siab valve yog lub valve uas nws lub npe siab PN yog tsawg dua 1.6MPa.

Lub nominal siab ntawm nruab nrab siab valve yog PN2.5 ~ 6.4MPa.

Lub siab siab valve muaj lub siab nominal ntawm PN10.0 ~ 80.0MPa.

Ultra-siab siab valve yog lub valve uas nws nominal siab PN siab tshaj 100MPa.

(2) Muab faib los ntawm qhov nruab nrab kub

Lub siab kub valve t yog siab tshaj 450C.

Qhov nruab nrab qhov kub thiab txias valve 120C yog tsawg dua li lub valve uas nws t yog tsawg dua 450C.

Qhov ntsuas kub li qub -40C tsawg dua t tsawg dua 120C.

Qhov ntsuas kub qis -100C yog tsawg dua t yog tsawg dua -40C.

Lub ultra-low kub valve t yog tsawg tshaj li -100C.

(3) Kev faib tawm los ntawm cov khoom siv lub cev valve

Cov ntaub ntawv uas tsis yog xim hlau: xws li ceramic li qub, iav steel li qub, yas li qub.

Cov khoom siv hlau: xws li tooj liab alloy li qub, aluminium alloy li qub, txhuas alloy li qub, titanium alloy li qub, Monel alloy li qub

Cam khwb cia hlau li qub, carbon steel li qub, cam khwb cia steel li qub, qis alloy steel li qub, siab alloy steel li qub.

Hlau lub cev hauv ob sab phlu li qub: xws li cov hlau lead-lined li qub, yas-lined li qub, thiab enamel-lined li qub.

General taxonomy

Qhov kev faib tawm no tau muab faib ua raws li txoj cai, kev ua haujlwm thiab cov qauv, thiab tam sim no yog cov txheej txheem kev faib tawm thoob ntiaj teb thiab hauv tsev.General rooj vag valve, ntiaj teb valve, throttle valve, ntsuas valve, plunger valve, diaphragm valve, ntsaws valve, pob valve, npauj npaim valve, kos valve, siab txo valve, kev nyab xeeb valve, ntxiab, tswj valve, ko taw valve, lim, Blowdown valve , lwm.
