Ivalvu yeBhola yokuNgena ephezulu
Ithini ivalvu yebhola yokungena ephezulu?
Xa kufikwa kwindlela umzimba osebenza ngayo, iivalvu zebhola zihlala zahlulwe zibeivalvu yebhola yokungena ecaleni,ivalvu yebhola yokungena ephezulukwayeivalvu yebhola edityanisiweyo ngokupheleleyo.
Iivalvu zebhola zokungena eziphezulu arIivalvu ezidibanisa ibhola yazo ukusuka kwicala eliphezulu. Zifana nevalvu yehlabathi enomzimba kunye nebhonethi ngaphandle kokuba inxalenye yokutrima isebenzisa uhlobo lwebhola. Zinomzimba omnye.Iivalvu zebhola zokungena eziphezulu zisetyenziswa kwiinkqubo zemibhobho apho umphezulu wevalvu unokususwa ukuze kufikelelwe kwibhola nakwizihlalo ngaphandle kokususa ivalvu yonke kwinkqubo yemibhobho.Iivalvu zebhola zokungena eziphezulu zihlala zisetyenziswa kwiinkqubo zenkqubo apho ukugcinwa kwemigca kukhethwa kunokususwa ngokupheleleyo kweevalvu. Ke ngoko kuqhelekile ukusebenzisa iivalvu zebhola zokungena eziphezulu xa kusetyenziswa uxinzelelo oluphezulu ezifuna ukugcinwa rhoqo njengeevalvu zeHIPPS (High Integrity Pressure Protection System) njl. Iingenelo zeevalvu zebhola zokungena eziphezulu kukwakhiwa kwazo okuvumela unxibelelwano oluncinci lwentambo ukuze kuncitshiswe nendlela enokwenzeka yokuvuza.
Kunokwenzeka ukususa ibhonethi yeIvalvu yebhola yokungena ephezuluukuvumela ukufikelela ngokukhululekileyo kwi-body cavity ngaphandle kokuqhawula ivalvu kumgca. Iseti yezixhobo ezikhethekileyo zokulungisa ivumela ukukhupha zombini iibhola kunye neeringi zezihlalo; olu lungiso aludingi sithuba sininzi kakhulu esijikeleze ivalvu, ngaloo ndlela luvumela ukuba ibekwe kwiindawo apho indawo ingumda.
Ulwakhiwo lwebhola lokungena eliphezuluIfumaneka ngendlela yokwenziwa okanye eyenziwe nge-cast, umzimba olinganayo one-piece enye uvalwe yibhonethi ebotshiweyo. Iqinisekisa ukuba inamandla aneleyo kunye nokuqina phantsi koxinzelelo oluphezulu lokusebenza olulinganisiweyo. Uluhlu luquka zombini i-Full kunye ne-Reduced bore, udidi lwe-ANSI loxinzelelo ukusuka kwi-150 ukuya kwi-1500, kunye nayo yonke indibaniselwano enokwenzeka ye-ENDS connections: i-flanged (RF-RTJ), i-butt welding kunye ne-HUB ends.

- Izikhokelo zesiqu kwisigqubuthelo kunye ne-gland bushing zisusa ukutyhala ecaleni. I-flange kunye ne-gland ezizilungelelanisayo ezimbini.
- I-gasket yomzimba engenasici evalwe ngokupheleleyo yi-spiral wound graphite.
- Isixhobo sokuhlamba esithwala izinto eziphilayo sithintela ukurhawuzelelwa kwaye sibonelela ngesitywino sesibini sesiqu.
- Uqhagamshelo lwe-ASME Section 8 kunye ne-bolting ye-cover/body flange zibonelela ngokuthembeka okuphezulu kwe-body gasket.
- Ivumela ukufikelela kwi-intanethi ukuze kutshintshwe isihlalo.
- Ingadityaniswa ibe yintambo ngaphandle kokuyiqhaqha ngokwemiyalelo yokufakela yeVelan.
- I-trim yentsimbi engenasici kuzo zonke iivalvu kuquka nesiphatho.
- Izibambo ezinesixhobo sokutshixa, kunye nezandiso ezikhoyo.
- Izixhobo zokutshixa ezisemgangathweni.
- Ukucofa ukuze ufake ii-actuators ezisemgangathweni.
- Iivalvu zinokuhlangabezana neemfuno ze-NACE zenkonzo yegesi emuncu xa kuyimfuneko.
- Umlilo uvavanywe ngokwe-API 607 Rev. 5/ISO 10497.
