Ivalve yokulawula ubushushu be-LNG
Ti-LNG i-valve yokulawula ubushushu obuphantsi iyasebenza kulawulo lokuhamba kwe-LNG phantsi kweemeko zokushisa eziphantsi.Kukho ikakhulu iindidi ezimbini: ivalve yesitulo esinye kunye nevalve yomkhono.Kwinkqubo yokulawula, injongo yoxinzelelo kunye nokulawulwa kokuhamba kufezekiswa ngokuguqula ubungakanani bendawo yokuhamba kwevalve.Olu luhlu lweevalvu zokulawula ubushushu obuphantsi zisetyenziselwa ukulawula ulwelo kunye negesi kunye nobushushu obuphantsi njenge-198℃.

Uhlobo lweCage iValve yoLawulo
Uhlobo lwekhejiulawuloivalve luhloboulawuloivelufa esebenzisa ikheji ebanzi yangaphakathi kunye nepiston ukulawula ukuhamba.Ulwakhiwo lomzimba olubanzi lunengqiqo, kwaye umjelo obanzi wangaphakathi wamanzi ulungelelaniswa.Ikwaxhotyiswe ngephiko lesikhokelo sokuphucula ukuhamba kwe-fluid balance, enokulahlekelwa kwengcinezelo encinci, ukuhamba okukhulu kwaye kunokulungiswa ngokubanzi.I-curve yeempawu zokuhamba inokuchaneka okuphezulu kunye nokuzinza okulungileyo okuguquguqukayo.Ingxolo ephantsi, i-cavitation corrosion ephantsi, ilungele ukulawula ulwelo lwenkqubo eyahlukeneyo.

Isitulo sokulawula iValve yesitulo esinye
Ivalve yokulawula isihlalo esinye yivalve yolawulo lwesakhiwo sesikhokelo esiphezulu.Isakhiwo somzimba samahhala siqinile, kwaye ukuhamba ngumzila we-S-streamline.Yonaincinciukwehla koxinzelelo,enkuluukuhamba, uluhlu olubanzi oluhlengahlengiswayo, ukuchaneka okuphezulu kweempawu, kunye nokumelana nokungcangcazela.Ivalve elawulayo inokuxhotyiswa nge-multi spring diaphragm actuator, ngamandla amakhulu aphumayo.Ilungele ukulawula ulwelo kunye nemidiya ephezulu ye-viscosity kunye noxinzelelo oluhlukeneyo kunye namaqondo obushushu.
