I-Top Entry Ball Valve
Iyini ivalvu yebhola yokungena ephezulu?
Uma kukhulunywa ngesitayela somzimba, ama-ball valve angahlukaniswa abeivalvu yebhola yokungena eceleni,ivalvu yebhola yokungena ephezulufuthii-valve yebhola ehlanganisiwe ngokugcwele.
Amavalvu ebhola okungena aphezulu arAma-valve e-e ahlanganisa ibhola lawo kusukela ohlangothini oluphezulu. Ifana ne-globe valve enomzimba kanye ne-bonnet ngaphandle kwengxenye yokunquma esebenzisa uhlobo lwebhola. Iqukethe umzimba owodwa.Amavalvu ebhola angena phezulu asetshenziswa ezinhlelweni zamapayipi lapho ingxenye ephezulu yevalvu ingasuswa ukuze kufinyelelwe ebholeni nasezihlalweni ngaphandle kokususa ivalvu yonke ohlelweni lwamapayipi.Amavalvu ebhola lokungena eliphezulu avame ukusetshenziswa ezinhlelweni zenqubo lapho ukulungiswa okusemgqeni kukhethwa khona kunokususwa kwamavalvu aphelele. Ngakho-ke kuvamile kakhulu ukusebenzisa amavalvu ebhola lokungena eliphezulu lapho kusetshenziswa umfutho ophezulu adinga ukulungiswa njalo njengamavalvu e-HIPPS (High Integrity Pressure Protection System) njll. Izinzuzo zamavalvu ebhola lokungena eliphezulu ukwakhiwa kwawo okuvumela ukuxhumeka okuncane kwentambo ukuze kuncishiswe nendlela yokuvuza okungenzeka.
Kungenzeka ukususa ibhonethi yeI-valve yebhola yokungena ephezuluukuvumela ukufinyelela mahhala emgodini womzimba ngaphandle kokudiliza ivalvu emgqeni. Isethi yamathuluzi okulungisa akhethekile ivumela ukukhipha kokubili ibhola kanye nezindandatho zezihlalo; lokhu kusebenza kokulungisa kudinga isikhala esincane kakhulu esizungeze ivalvu, ngaleyo ndlela kuyivumela ezindaweni lapho isikhala siyisici esinqunyelwe khona.
Ukwakhiwa kwebhola lokungena okuphezuluitholakala ngendlela yokwenziwa noma eyenziwe ngensimbi, umzimba olinganayo onengxenye eyodwa ovalwe yibhonethi eboshwe ngebhalti. Iqinisekisa ukuthi inamandla anele nokuqina ngaphansi kwengcindezi yokusebenza elinganisiwe ephezulu. Ububanzi buhlanganisa kokubili ibhore eligcwele nelincishisiwe, isigaba se-ANSI sokucindezela kusukela ku-150 kuya ku-1500, nazo zonke inhlanganisela ezingaba khona zokuxhumeka kwe-ENDS: i-flanged (RF-RTJ), i-butt welding kanye ne-HUB ends.

- Ilungu elimboza umzimba alithinteki ngenxa yokucindezeleka kwamapayipi.
- Iziqondiso zesiqu esisembozweni kanye nasesigxotsheni se-gland zisusa ukuphonswa eceleni. I-flange kanye ne-gland ezizilungisayo ezizicucu ezimbili.
- I-gasket yomzimba engagqwali egcwele i-spiral wound graphite evalwe ngokuphelele.
- I-washer ethwala izinto eziphilayo ivimbela ukugabha futhi inikeza isivalo sesibili sesiqu.
- Ukuxhumeka kwe-ASME Section 8 kwe-flange yesembozo/umzimba kanye ne-bolting kunikeza ukuqina okuphezulu kokuvala kwe-gasket yomzimba.
- Ivumela ukufinyelela okuqondile kokushintsha isihlalo.
- Ingashintshwa ibe yintambo ngaphandle kokuyiqaqa ngokuhambisana nemiyalelo yokufaka ye-Velan.
- Ukuhlobisa ngensimbi engagqwali kuwo wonke amavalvu kufaka phakathi isibambo.
- Izibambo ezinedivayisi yokukhiya, kanye nezandiso ezitholakalayo.
- Amadivayisi okukhiya ajwayelekile.
- Ukuthepha ukuze ufake ama-actuator ajwayelekile.
- Amavalvu angahlangabezana nezimfuneko ze-NACE zesevisi yegesi emuncu uma kudingeka.
- Umlilo uhlolwe ngokuvumelana ne-API 607 Rev. 5/ISO 10497.
Ukucaciswa kobuchwepheshe kwe-valve yebhola yokungena ephezulu
I-NORTECHyakha umklamo othuthukisiwe we amavalvu ebhola angena phezulukububanzi obuphelele bezigaba zobubanzi kanye nengcindezi. Amavalvu aphezulu ayisinqumo esifanele uma kudingeka ukulungiswa ku-inthanethi.

Imikhiqizo iboniswa
Ukusetshenziswa kwama-valve ebhola lokungena eliphezulu
Inezinzuzo ezifana nomsebenzi wokulungisa osezingeni eliphezulu ku-inthanethi, ukumelana noketshezi okuncane, isakhiwo esilula, ukuvalwa okuthembekile, ukusebenza okulula nokugcinwa, ukusebenza okusheshayo kokuvula, ukuvulwa nokuvala okuguquguqukayo, njll.
Lolu hlobo lweI-Top Entry Ball Valve Isetshenziswa kabanzi ohlelweni lokusebenzisa, lokuhlanza nokuthutha uwoyela, igesi kanye namaminerali. Ingasetshenziswa futhi ukukhiqiza imikhiqizo yamakhemikhali, imithi; uhlelo lokukhiqiza ugesi wamanzi, amandla okushisa kanye namandla enuzi; uhlelo lokukhipha amanzi, olusetshenziswa kabanzi emapayipini nasezinhlelweni zezimboni. Ikakhulukazi ekusetshenzisweni lapho kudingeka ukulungiswa kwe-inthanethi.
