Ivalvu yebhabhathane ephindwe kabili iwukuthi i-axis yesiqu sevalvu iphambuka kokubili phakathi kwepuleti lebhabhathane kanye naphakathi komzimba. Ngokusekelwe ekungangeni okuphindwe kabili, i-sealing pair yevalvu yebhabhathane ephindwe kathathu iguqulwa ibe yi-integrated cone.

Ukuqhathaniswa kwesakhiwo:

Zombili ivalvu yebhabhathane ephindwe kabili kanye nevalvu yebhabhathane ephindwe kathathu engavamile zingenza ipuleti lebhabhathane liphume ngokushesha esihlalweni sevalvu ngemva kokuvulwa, ziqede kakhulu ukuphuma ngokweqile okungadingekile kanye nokuklwebheka phakathi kwepuleti lebhabhathane nesihlalo sevalvu, zinciphise ukumelana kokuvulwa, zinciphise ukuguguleka futhi zithuthukise impilo yesihlalo sevalvu.

Ukuqhathaniswa kwezinto ezibonakalayo:

Izingxenye eziyinhloko zokucindezela zevalvu yebhabhathane ephindwe kabili zenziwe ngensimbi ethambile, kanti izingxenye eziyinhloko zokucindezela zevalvu yebhabhathane emithathu ethambile zenziwe ngensimbi ethambile. Amandla ensimbi ethambile kanye nensimbi ethambile ayalingana. Insimbi ethambile inamandla aphezulu okukhiqiza, enamandla aphansi okukhiqiza angu-310mpa, kanti amandla okukhiqiza ensimbi ethambile angama-230MPa kuphela. Eziningi zezicelo zikamasipala, njengamanzi, amanzi anosawoti, umusi, njll., ukumelana nokugqwala kanye nokumelana nokushiswa kwensimbi ethambile kungcono kunokwensimbi ethambile. Ngenxa yesakhiwo se-graphite esiyisiphepho sensimbi ethambile, insimbi ethambile ingcono kunensimbi ethambile ekunciphiseni ukudlidliza, ngakho-ke ilungele kakhulu ukunciphisa ukucindezeleka.

Ukuqhathanisa umphumela wokuvala:

Ivalvu yebhabhathane ephindwe kabili engavamile isebenzisa isihlalo esibanzi nesintantayo. Ngaphansi kwengcindezi enhle, ukuvuleka okubangelwa ukubekezelelana komshini kanye nokuguquka komgodi we-valve kanye nepuleti lebhabhathane ngaphansi kwengcindezi ephakathi kwenza ubuso obuyindilinga bepuleti lebhabhathane bulingane kakhulu ebusweni bokuvala besihlalo se-valve. Ngaphansi kwengcindezi embi, isihlalo esintantayo siya ekucindezelweni okuphakathi ngaphansi kwengcindezi ephakathi, sibuyisela ngempumelelo ukuvuleka okubangelwa ukubekezelelana komshini kanye nokuguquka komgodi we-valve kanye nepuleti lebhabhathane ngaphansi kwesenzo sengcindezi ephakathi, ukuze kufezwe ukuvalwa okuphambene.

I-valve ye-butterfly eqinile engavamile emithathu isebenzisa isihlalo se-valve esiqondile esiqondile kanye nendandatho yokuvala enamazinga amaningi. Ngaphansi kwengcindezi enhle, ukuvuleka okubangelwa ukubekezelelana komshini kanye nokuguquguquka komgodi we-valve kanye nepuleti le-butterfly ngaphansi kwengcindezi ephakathi kwenza indandatho yokuvala enamazinga amaningi ilingane kahle ebusweni bokuvala besihlalo se-valve, kodwa ngaphansi kwengcindezi ebuyela emuva, indandatho yokuvala enamazinga amaningi izoba kude kakhulu nobuso bokuvala besihlalo se-valve, Ngakho-ke, ukuvala okubuyela emuva akukwazi ukufezwa.
