Umehluko phakathi kweValve Yebhola Elintantayo kanye Nevalve Yebhola Elikhweziwe I-Trunnion

1. Ukubukeka

1.1.Ivalve yebhola elintantayo kanye nevalve yebhola efakwe ku-trunnion kuselula ukuhlukanisa ngokubukeka.Uma umzimba we-valve une-shaft engashintshi ephansi, kufanele kube i-valve yebhola efakwe nge-trunnion.(Ungabhekisela ekubukeni kwe-valve yebhola kusuka ku-RXVAL Valves).

1.2.Uma kune-valve yamafutha emzimbeni we-valve yebhola, ngokuyisisekelo i-valve yebhola efakwe nge-trunnion.

Kodwa okuphambeneyo akulona iqiniso.Akulungile ukuba ne-valve yebhola elintantayo ngaphandle kwevalve yamafutha, ngoba usayizi omncane ofana nevalvu yebhola engu-1″ 300LB trunnion egijiswe ngokuvamile ayinayo ivalvu yamafutha.(Ungabhekisela ekubukeni kwe-valve yebhola ye-RXVAL)

2. Isimiso Sokusebenza

2.1 Ibhola le-valve yebhola elintantayo linesiqu esiphezulu kuphela, futhi ibhola alinayo i-shaft esekelayo.Ngaphansi kwesenzo somehluko wengcindezi, ibhola lingasuswa kancane, ngakho libizwa ngokuthi i-valve yebhola elintantayo.

Kukhona ne-fixed shaft ezansi kwe-trunnion mounted ball valve, elungisa indawo yebhola, ukuze ingakwazi ukususwa, ngakho ibizwa ngokuthi i-trunnion mounted ball valve.

2.2 Ibhola le-valve yebhola elintantayo liyasuswa ngenxa yokucindezela kwe-medium, futhi linamathiselwe ngokuqinile esihlalweni se-valve ukuze kutholakale ukuvala.Kuyadingeka ukucabangela ukuthi impahla yesihlalo ingakwazi ukumelana nokucindezela kokusebenza.

Ibhola le-trunnion mounted ball valve lilungisiwe, futhi isihlalo sinyakaziswa ukucindezela kwe-medium, futhi linamathele ngokuqinile ebhola ukuze kuzuzwe uphawu.

3. Umsebenzi kanye nokusetshenziswa

3.1 I-valve yebhola elintantayo ifanele ukucindezela okuphakathi nendawo nokuphansi, futhi ububanzi buncane;ivalve yebhola efakwe ku-trunnion ingamelana nokufika ku-2500LB, futhi ubukhulu bungafinyelela kuma-intshi angu-60.Isibonelo, i-valve yebhola enobubanzi obukhulu kanye ne-high-pressure ye-RXVAL i-trunnion mounted ball valve.

3.2 I-valve yebhola efakwe ku-Trunnion ingabona ukusebenza kweGazi eliphindwe kabili kanye Nokuphuma kwegazi, kuyilapho i-valve yebhola elintantayo ngokuvamile iyindlela eyodwa.I-valve yebhola efakwe ku-trunnion ingavimba okuphakathi kuzo zombili iziphetho ezikhuphuka nomfula ngesikhathi esisodwa.Lapho ukucindezela emgodini womzimba we-valve kungaphezu kwamandla aqinisayo entwasahlobo yesihlalo se-valve, isihlalo se-valve sizophushwa sivuleke ukuze sikhulule ukucindezela emgodini ukuze kuqinisekiswe ukuphepha.

3.3 Amavalvu ebhola afakwe ku-Trunnion avamise ukuba nempilo ende kunamabhola antantayo.Ngokwempendulo yomsebenzisi, i-valve yebhola engashintshi ye-RXVAL isetshenziswe iminyaka engu-10 ngaphandle kwezinkinga.

3.4 I-torque ye-valve yebhola efakwe ku-trunnion incane kunaleyo ye-valve yebhola elintantayo, ngakho-ke ukusebenza kusindisa umsebenzi.

3.5 Ivalve yebhola efakwe ku-trunnion ngaphezu kwama-intshi angu-4 ifakwe i-valve yamafutha esihlalo, kodwa i-valve yebhola elintantayo ayinayo.

3.6 Ukusebenza kokuvalwa kwe-valve yebhola efakwe ku-trunnion kunokwethenjelwa kakhulu: indandatho eyodwa ye-PTFE yokuvala impahla ishunyekwe esihlalweni sevalvu yensimbi engagqwali, futhi umsila wokuphela kwesihlalo se-valve yensimbi unikezwa isiphethu sokuqinisekisa amandla anele okuqinisa ngaphambi kokuqina. kwendandatho yokuvala.I-valve iyaqhubeka nokuqinisekisa ukusebenza okuhle kokuvala ngaphansi kwesenzo sentwasahlobo.

3.7 Ivalve yebhola efakwe ku-trunnion ine-valve yagrisi, enomsebenzi wokujova igrisi yokuvala uma i-valve ivuza.

3.8 Isikhumbuzi sobungani se-RXVAL, Uma i-valve yebhola yokucaciswa okufanayo, ivalve yebhola efakwe ku-trunnion ngokuvamile ibiza kakhulu kune-valve yebhola elintantayo.
