Ukubuka konke

I-valve yebhola elintantayo isetshenziswa kakhulu ekusetshenzisweni komfutho ophakathi noma ophansi (ngaphansi kuka-900LB), futhi imvamisa ithola umzimba wama-pcs amabili noma ama-pcs amathathu. Nakuba isakhiwo salolu chungechunge silula kodwa ukusebenza kokuvala kuthembekile.

• Ibhola Elintantayo

• Umzimba Ohlukanisiwe, Umzimba Oyizingcezu Ezi-2 noma Ezi-3

• Ukuphela Kokungena

• Isivikelo Somlilo ku-API 607

• Umklamo Ongaguquki

• Ukuvimbela ukushaqeka

• I-torque ephansi

• Khiya idivayisi

a) Ukuklama Nokukhiqiza: I-API 6D, i-BS 5351, i-ASME B16.34, i-API 608

b) Ubuso Nobuso: API 6D, API B16.10, EN 558, DIN 3202

c) Ukuxhumana Kokugcina: ASME B16.5, ASME B16.25, EN 1092, GOST 12820

d) Ukuhlolwa Nokuhlolwa: I-API 6D, EN 12266, i-API 598

Blisiqu esingenasiqiniseko

Ngenhloso yokuvimbela isiqu ukuba singandizi okuholela ekukhuphukeni okungavamile kwengcindezi yangaphakathi yevalvu, ihlombe liqiniswa engxenyeni engezansi yesiqu. Ngaphezu kwalokho, ukuze kuvinjelwe ukuvuza okubangelwa ukusha kwesethi yokupakisha yesiqu emlilweni, i-thrust bearing ibekwa endaweni yokuxhumana yehlombe engxenyeni engezansi yesiqu kanye nomzimba wevalvu. Ngakho-ke kwakhiwa isihlalo sokuvala esiphambene esizovimbela ukuvuza futhi sigweme ingozi.

Idizayini ephephile yokulwa nomlilo

Uma kwenzeka umlilo ngesikhathi kusetshenziswa i-valve, indandatho yesihlalo eyenziwe ngezinto ezingezona ezensimbi izolimala ngaphansi kokushisa okuphezulu. Lapho isihlalo kanye nendandatho ye-O kushiswa, isibambi sesihlalo kanye nomzimba kuzovalwa nge-graphite evikela umlilo.

Idivayisi elwa nokungaguquguquki

I-valve yebhola inikezwe isakhiwo esilwa nokuma futhi isebenzisa idivayisi yokukhipha ugesi ongaguquki ukuze yakhe ngqo isiteshi esingaguquki phakathi kwebhola nomzimba noma yakhe isiteshi esingaguquki phakathi kwebhola nomzimba ngesiqu, ukuze ikhiphe ugesi ongaguquki okhiqizwa ngenxa yokungqubuzana ngesikhathi sokuvulwa nokuvalwa kwebhola nesihlalo ngepayipi, igweme umlilo noma ukuqhuma okungase kubangelwe yinhlansi engaguquki nokuqinisekisa ukuphepha kohlelo.

I-NSEN ilandela ngokuqinile ukulungiswa kwamahhala, ukushintshwa kwamahhala kanye nezinsizakalo zokubuyiselwa kwamahhala zingakapheli izinyanga eziyi-18 ngemuva kokuthi ivalvu isisebenzile noma izinyanga eziyi-12 ngemuva kokufakwa nokusetshenziswa epayipini ngemuva kokusebenza kwangaphambilini (okuzofika kuqala). 

Uma kwenzeka ivalvu yehluleka ngenxa yenkinga yekhwalithi ngesikhathi sokusetshenziswa epayipini ngaphakathi kwesikhathi sewaranti yekhwalithi, i-NSEN izohlinzeka ngensizakalo yewaranti yekhwalithi yamahhala. Insizakalo ngeke iphele kuze kube yilapho ukwehluleka sekulungisiwe futhi ivalvu ivame ukusebenza futhi iklayenti lisayina incwadi yokuqinisekisa.

Ngemva kokuphela kwesikhathi esishiwo, i-NSEN iqinisekisa ukuhlinzeka abasebenzisi ngezinsizakalo zobuchwepheshe ezisezingeni eliphezulu ngesikhathi noma nini lapho umkhiqizo udinga ukulungiswa nokunakekelwa.
