Fais npauj npaim valve yog hom kev tswj kev ntsuas valve. Nws cov nres nres yog ib qho qub lossis disc, thiab nws qhov tseem ceeb yog tsim los ntawm kev lag luam roj Circuit Court, lub tog raj txuas, lub disc thiab lub nplhaib sib khi. Cov roj Circuit Court board yog cylindrical, radial thiab luv nyob rau hauv ntev, thiab muaj ib lub npauj npaim phaj. Npauj npaim phaj ntawm npauj npaim valve yog tsau rau ntawm txoj kab uas hla ntawm cov yeeb nkab. Nyob rau hauv txoj kev nyab xeeb cylindrical txoj kab npauj npaim valve roj Circuit Court board, disc-puab npauj npaim phaj phaj tig ncig ntawm txoj kab nruab nrab nrog kev sib hloov kaum ntawm 0 ° txog 95 °. Thaum tig mus rau 95 °, lub rooj vag lub rooj vag yuav puv. Nws tau qhib.
Cov hluav taws xob npauj npaim valve yog yooj yim hauv cov qauv, pom hauv qhov hnyav, lub teeb heev, thiab muaj ntau ntu. Tsis tas li ntawd, nws siv tau yooj yim vim tias nws tuaj yeem qhib thiab kaw sai sai los ntawm tsuas yog tig 95 °. Nyob rau tib lub sijhawm, lub rooj vag valve muaj hluav taws xob zoo ua haujlwm. Thaum npauj npaim npauj valve nyob rau hauv txoj haujlwm qhib tag nrho, qhov kev sib txhuam tsis sib haum thaum cov khoom ntws los ntawm cov roj Circuit Court phaj tsuas yog tuab ntawm npauj npaim phaj, yog li cov cua siab tsim los ntawm lub rooj vag valve tsis loj thiab zoo. Ntws xyuas feature. Npauj npaim li qub muaj ob hom ntsaws ruaj ruaj: ntsaws ruaj ruaj thiab cov ntsaws ruaj ruaj rau hlau. Rau malleable kaw rooj vag li qub, lub nplhaib sib txuas tuaj yeem ntsia tau rau hauv cov roj Circuit Court board los yog ze ntawm npauj npaim phaj.
