Khoom Description

Npauj npaim valve, hu ua npauj npaim valve, hais txog lub valve uas nws cov tswvcuab kaw (valve disc lossis npauj npaim phaj) yog lub disc thiab tig ib ncig ntawm lub valve axis kom qhib thiab kaw. Nws yog tsuas yog siv rau kev txiav thiab throttling ntawm cov kav dej.

Npauj npaim valve, hu ua npauj npaim valve, yog ib hom throttle valve thiab yog ib qho khoom siv tseem ceeb hauv cov dej thiab cov kav dej. Nrog rau kev nce qib ntawm kev lag luam thev naus laus zis, cov kev xav tau sib txawv tau muab tso rau pem hauv ntej rau cov qauv thiab kev ua haujlwm ntawm npauj npaim li qub. Yog li ntawd, thaum tsim thiab xaiv, kev xaiv tsim nyog yuav tsum tau ua raws li hom, khoom siv, thiab daim ntawv sib txuas raws li kev ua haujlwm.

3 Hom Npauj Npaim Npauj Npaim Valve

Txawm hais tias lub luag haujlwm ntawm cov li qub no tseem ceeb ib yam, muaj ntau qhov kev hloov pauv hauv npauj npaim valve tsim kom haum rau kev ua haujlwm sib txawv. Cov hauv qab no yog peb lub ntsiab npauj npaim valve hom:

● Zero offset npauj npaim valve

"Concentric" lossis "rubber seat" yog lwm lub npe rau xoom-offset designs. Zero deflection txhais tau hais tias tsis muaj deflection hauv lub valve qia. Lub valve raug kaw los ntawm kev cuam tshuam ntawm lub disc thiab lub rooj zaum roj hmab raws ntug ntawm lub disc ntawm lub qia valve.

Roj hmab rooj zaum li qub muaj qhov ntsuas siab qis tshaj plaws (txog 250 PSI) thiab tuaj yeem tiv taus qhov kub txog li 400 degree F. Nws lub rooj zaum roj hmab puag ncig lub cev thiab tiv thaiv kev sib cuag nrog cov khoom siv, yog li tswj cov purity ntawm kev tshaj tawm.

● Kev ua haujlwm siab ob chav eccentric npauj npaim valve

Lub npauj npaim valve no yog hu ua ob chav eccentric vim hais tias qhov eccentricity nyob rau hauv ob qhov chaw: ntawm kab ntawm lub rooj zaum / lub cev foob thiab ntawm lub bore. Off-center positioning pab txhim kho lub sealing durability. Cov kev ua haujlwm siab tuaj yeem tiv taus siab txog 1440 PSI thiab kub txog 1200 degree F.

Thaum thawj 10 degrees ntawm kev qhib thiab 10 degrees ntawm kev kaw ntawm 90 degree kev sib hloov, lub valve qia rubs qab lub disc, tsim ib qho kev ua camming.

● Triple offset npauj npaim valve

Qhov zoo tshaj plaws npauj npaim valve hom rau kev kub siab tshuab yog triple offset npauj npaim valve. Ntawm peb hom, triple offset yog qhov siab tshaj plaws, muaj qis dua emissions, thiab yog tsim los siv rau ntau qhov chaw. Nws qhov kub tsis kam yog 1200 degree F vim nws tuaj yeem tiv taus 1,480 PSI ntawm lub siab.

Zoo li ob lub offset valve, triple offset valve muaj ob lub eccentric li qub nyob rau hauv qhov chaw, tab sis lub thib peb eccentric valve muaj ib tug cam kev txiav txim nrog lub kaum sab xis lub khob hliav qab foob. Txij li cov hlau sealing qhov chaw tsis tiv tauj mus txog qhov kawg taw tes, lawv tsis muaj kev sib txhuam thiab hnav-tiv taus.
