Umahluko phakathi kweValve yeBhola edadayo kunye neTrunnion eMounted valve yeBhola

1. Imbonakalo

1.1.Ivalve yebhola edadayo kunye nevalve yebhola efakwe kwitruni kuselula ukwahlula ngenkangeleko.Ukuba umzimba wevalve uneshafti esezantsi ezinzileyo, kufuneka ibe ivelufa egxunyekiweyo yebhola.(Ungabhekisa kwinkangeleko yevalve yebhola esuka kwi-RXVAL Valves).

1.2.Ukuba kukho ivalve yegrisi kumzimba wevalve yebhola, ngokuqhelekileyo yivalve yebhola efakwe kwitrunnion.

Kodwa okuchaseneyo akuyonyani.Akulunganga ukuba nevalve yebhola edadayo ngaphandle kwevalve yegrisi, kuba ubungakanani obuncinci obufana ne-1″ 300LB trunnion valve yebhola egxunyekweyo ayinaso ivalve yegrisi.(Ungabhekisa kwinkangeleko yevalve yebhola ye-RXVAL)

2. UmGaqo wokuSebenza

2.1 Ibhola yevalve yebhola edadayo inesiqu esiphezulu kuphela, kwaye ibhola ayinayo i-shaft exhasayo.Ngaphantsi kwesenzo somohluko woxinzelelo, ibhola inokususwa kancinane, ngoko ibizwa ngokuba yivalve yebhola edadayo.

Kukho kwakhona i-shaft esisigxina emazantsi e-trunnion efakwe kwi-valve yebhola, elungisa indawo yebhola, ngoko ayikwazi ukukhutshwa, ngoko ibizwa ngokuba yi-valve yebhola efakwe kwi-trunnion.

2.2 Ibhola yevalve yebhola edadayo iyasuswa ngenxa yoxinzelelo lwe-medium, kwaye incamathele ngokuqinileyo kwisitulo sevalve ukufezekisa ukutywinwa.Kuyimfuneko ukuqwalasela ukuba izinto eziphathekayo zesihlalo zinokumelana noxinzelelo lokusebenza.

Ibhola ye-trunnion efakwe kwi-valve yebhola igxininiswe, kwaye isihlalo sishukunyiswa nguxinzelelo lwe-medium, kwaye ifakwe ngokuqinileyo kwibhola ukufezekisa ukutywinwa.

3. Umsebenzi kunye nokusebenzisa

3.1 Ivalve yebhola edadayo ifanelekile kuxinzelelo oluphakathi kunye noluphantsi, kwaye ububanzi buncinci;Ivalve yebhola efakwe kwitrunnion inokumelana ukuya kuthi ga kwi-2500LB, kwaye ubungakanani bunokufikelela kwi-intshi ezingama-60.Umzekelo, ivalve yebhola enedayamitha enkulu kunye noxinzelelo oluphezulu lwe-RXVAL yivalve yebhola ene-trunnion.

3.2 Ivalve yebhola efakwe kwi-Trunnion inokuqonda ukusebenza kweGazi eliphindwe kabini kunye nokuBopha, ngelixa ivalve yebhola edadayo ubukhulu becala ivalwa indlela enye.Ivalve yebhola efakwe kwi-trunnion inokuvalela okuphakathi kuzo zombini iziphelo zomlambo ezisezantsi nasezantsi ngaxeshanye.Xa uxinzelelo kumngxuma womzimba wevalvu lungaphezulu kwamandla okuqinisa entwasahlobo yesitulo sevalvu, isitulo sevalvu siya kutyhala sivuleke ukukhulula uxinzelelo kumngxuma ukuqinisekisa ukhuseleko.

3.3 Iivalvu zebhola ezifakwe kwi-trunnion zikholisa ukuba nobomi obude kuneevalvu zebhola ezidadayo.Ngokwengxelo yomsebenzisi, ivalve yebhola esisigxina ye-RXVAL isetyenziswe iminyaka eyi-10 ngaphandle kweengxaki.

3.4 Itorque yevalve yebhola efakwe kwitrunnion incinci kunaleyo yevalve yebhola edadayo, ngoko ke ukusebenza kusindisa abasebenzi ngakumbi.

3.5 Ivalve yebhola efakwe kwi-trunnion ngaphezu kwee-intshi ezi-4 ifakwe ivalve yesitulo segrisi, kodwa ivalve yebhola edadayo ayinayo.

3.6 Ukusebenza kokutywinwa kwevalve yebhola efakwe kwi-trunnion ithembeke ngakumbi: i-PTFE ikhonkco lokutywina enye into ifakwe kwisihlalo sevalve yensimbi engenasici, kwaye isiphelo somsila wesihlalo sevalve yesinyithi sinikezelwa ngentwasahlobo ukuze kuqinisekiswe amandla okwaneleyo okuqinisa kwangaphambili. womsesane wokutywina.I-valve iyaqhubeka nokuqinisekisa ukusebenza kakuhle kokutywinwa phantsi kwesenzo sentwasahlobo.

3.7 Ivalve yebhola efakwe kwitrunnion inevalve yegrisi, enomsebenzi wokutofa igrisi yokutywina xa ivelufa ivuza.

3.8 Isikhumbuzi sobuhlobo se-RXVAL, Ukuba ivalve yebhola ekwingcaciso efanayo, ivalve yebhola efakwe kwitrunnion ixabisa ngokubanzi kunevalve yebhola edadayo.
