Ivalve yebhola yokungena ephezulu
Ithini ivalve yebhola yokungena ephezulu?
Uma kukhulunywa ngesitayela somzimba, ama-valve ebhola ngokuvamile angahlukaniswa abei-valve yebhola yokungena ohlangothini,i-valve yebhola yokungena ephezulufuthii-valve yebhola eshiselwe ngokuphelele.
Ama-valve amabhola okungena aphezulu aramavalvu e-e ahlanganise ibhola layo ukusuka engxenyeni ephezulu eseceleni.Kufana nevalvu yeglobhu enomzimba nebhonethi ngaphandle kwengxenye yokunquma esebenzisa uhlobo lwebhola.Yakha umzimba owodwa.Ama-valve amabhola okungena aphezulu asetshenziswa ezinhlelweni zamapayipi lapho ingxenye engaphezulu ye-valve ingasuswa ukuze kufinyelelwe ebholeni nasezihlalweni ngaphandle kokukhipha i-valve yonke ohlelweni lwamapayipi.Ama-valve amabhola okungena aphezulu avame ukusetshenziswa ezinhlelweni zenqubo lapho ukulungiswa kwe-in-line kukhethwa ngaphezu kokukhishwa okugcwele kwe-valve.Ngakho-ke kuvame kakhulu ukusebenzisa amavalvu ebhola okungena aphezulu ekufakweni komfutho ophezulu odinga ukulungiswa njalo okufana namavalvu e-HIPPS (High Integrity Pressure Protection System) njll. Ubuhle bamavalvu ebhola okungena aphezulu ukwakhiwa kwawo okuvumela ukuxhumana kwentambo okuncane ukuthi kuzophinde kunciphise indlela yokuvuza okungenzeka.
Kungenzeka ukususa ibhonethi yeI-valve yebhola yokungena ephezuluukuvumela ukufinyelela kwamahhala emgodini womzimba ngaphandle kokudiliza i-valve emgqeni.Iqoqo lamathuluzi okulungisa akhethekile livumela ukukhipha kokubili ibhola nezindandatho zokuhlala;lokhu kusebenza kokulungisa kudinga indawo encane kakhulu ezungeze i-valve, ngaleyo ndlela kuvumeleke ezindaweni lapho isikhala siyisici esilinganiselwe.
Ukwakhiwa kwebhola eliphezulu lokungenaitholakala ngokwenziwa komgunyathi noma okulingisi, umzimba olinganayo wocezu olulodwa ovalwe ngebhonethi eboshiwe.Iqinisekisa ukuthi inamandla anele kanye nokuqina ngaphansi kwengcindezi yokusebenza elinganiselwe ephezulu.Ububanzi buhlanganisa kokubili i-Full and Reduced bore, i-pressure class ANSI ukusuka ku-150 kuya ku-1500, nayo yonke inhlanganisela engenzeka yokuxhumana kwe-ENDS: flanged (RF-RTJ), i-butt welding futhi I-HUB iyaphela.

- I-graphite yenxeba evalekile evaleke ngokugcwele igcwalise i-gasket yomzimba engenasici.
- I-thrust washer elayishwa bukhoma ivimbela ukugabha futhi inikeza uphawu lwesibili lwesiqu.
- Isembozo se-ASME Isigaba 8/ukuxhumana kwe-flange yomzimba kanye nokufaka ibhawudi kunikeza ubuqotho bokuvalwa okuphezulu kwe-gasket yomzimba.
- Ivumela ukufinyelela kulayini ukuze kushintshwe isihlalo.
- Kungenziwa ashiselwe emgqeni ngaphandle disassembly ngokuhambisana Velan imiyalelo yokufaka.
- I-Stainless steel trim kuwo wonke ama-valve kuhlanganise nesibambo.
- Izibambo ezinedivayisi yokukhiya, kanye nezandiso ezitholakalayo.
- Amadivayisi okukhiya ajwayelekile.
- Ukuthepha okujwayelekile kwama-actuator.
- Amavaluvu angahlangabezana nokucaciswa kwe-NACE kwesevisi yegesi emuncu uma kudingeka.
- Umlilo uhlolwe ngokuvumelana ne-API 607 Rev. 5/ISO 10497.
Ukucaciswa kobuchwepheshe kwevalve yebhola yokungena ephezulu
I-NORTECHuthuthukise umklamo othuthukisiwe we ama-valve ebhola okungena phezuluebangeni elibanzi eliphelele lamadayamitha kanye namakilasi okucindezela.Ama-valve okungena phezulu ayisinqumo esihle uma ukugcinwa kwe-inthanethi kuyadingeka.

Ukusetshenziswa kwama-valve ebhola okungena aphezulu
Inezinzuzo ezinjengomsebenzi wokulungisa okuphezulu ku-inthanethi, ukumelana noketshezi oluncane, isakhiwo esilula, ukubekwa uphawu okuthembekile, ukusebenza okulula nokugcinwa, ukusebenza ngokushesha kokuvala, ukuvula nokuvala okuguquguqukayo, njll.
Lolu hloboIvalve yebhola yokungena ephezulu isetshenziswa kabanzi ohlelweni lokuxhaphaza, lokucwengisiswa nokuthutha uwoyela, igesi namaminerali.Ingase futhi isetshenziselwe ukukhiqiza imikhiqizo yamakhemikhali, imithi;uhlelo lokukhiqiza logesi ophehlwa ngamanzi, amandla ashisayo namandla enuzi;uhlelo lokudonsa amanzi, olusetshenziswa kakhulu kumapayipi kanye nasezinhlelweni zezimboni.ikakhulukazi ekufakeni isicelo uma ukugcinwa kwe-inthanethi kudingekile.
