API 6A Wellhead manual na hydraulic Choke Valves

Ibisobanuro bigufi:

Valve yo gufunga ni igice cy'ingenzi cy'igiti cya Noheli kandi yagenewe kugenzura umusaruro w'amazi y'ikigega cy'amavuta, ibikoresho by'umubiri n'ibice bya valve yo gufunga bihuye neza na API 6A na NACE MR-0175 Standard Specifications, kandi ikoreshwa cyane mu gucukura peteroli mu nyanja no mu nyanja. Valve yo gufunga ikoreshwa cyane cyane mu guhindura imiterere n'umuvuduko wa sisitemu ya manifold; Hari ubwoko bubiri bwa valve zo kugenzura ubwiyongere bw'amazi: zihamye n'izishobora guhindurwa. Valve zo gufunga zishobora guhindurwa zigabanyijemo ubwoko bw'inshinge, ubwoko bw'ingofero y'ingofero, ubwoko bw'ingofero y'ingofero n'ubwoko bw'ikigega cy'ingofero hakurikijwe imiterere; Dukurikije uburyo bwo gukora, ishobora kugabanywamo ibice bibiri by'intoki n'iby'amazi. Iherezo ry'ingofero ya Valve yo gufunga ni umugozi cyangwa Flange, ihujwe na non cyangwa flange. Valve yo gufunga igwamo: valve yo gufunga, valve yo gufunga, valve yo gufunga, valve yo gufunga na valve yo gufunga, n'ibindi.

Ibisobanuro birambuye ku gicuruzwa

Ibirango by'ibicuruzwa

Ibiranga

1.Umuvuduko w'akazi: 2000-15000 psi
2. Imbere mu gipimo cy'izina: 1 13/16”~7 1/16”
3. Ubushyuhe bw'akazi: PU
4. Urwego rw'ibicuruzwa: PSL1 ~ 4
5. Ibisabwa mu mikorere: PR1
6. Icyiciro cy'ibikoresho: AA - FF
7. Uburyo bwo gukorera: peteroli, gaze karemano, nibindi.

Ibyuma bigenzura amazi bigengwa n’amazi bihindura ingano y’umunwa w’umunwa kugira ngo bihindure agace k’umunwa w’amazi. Umunwa w’umunwa ukozwe muri karubide ya ceramic cyangwa sima, ifite ubushobozi bwo kudashira no kudashwanyagurika, kandi iyisimbura ikoresha ibikoresho byihariye, byihuse kandi byoroshye. Igice cy’umunwa w’umunwa n’ingofero bihuzwa na non, byoroshye gusenya.

Vali zo ku ruziga za Orifice plate zikoresha ikanya izunguruka kugira ngo zikoreshe ihuriro ry’intebe, muri rusange zikenera kuzunguruka ikanya kuri dogere 90 cyangwa 180 kugira ngo zifungure kandi zifunge vali. Impera ebyiri z’ikanya zishyirwamo kandi zigashyirwa mu myanya yazo, ibyo bikanoza ubukana bw’ikanya kandi bikagabanya guhindagura kwayo, kugira ngo imikorere y’ikanya ibe yoroshye kandi itekanye. Hamwe n’ibikoresho bikoresha amazi, umwuka n’amashanyarazi, vali yo ku ruziga ya orifice plate ishobora kugera ku buryo bwo kuyihindura neza, bityo vali yo ku ruziga ya orifice plate ikoreshwa cyane.

Valve yo mu bwoko bwa "throttle" ikoresha agace ka "valve" gakozwe mu buryo bw'ibumba, karwanya umuvuduko mwinshi no gukaraba. Ikoreshwa n'intoki, imiterere yoroshye, ikiguzi gito cyo kuyisana. Uburyo bwo kuyikoresha ni bwinshi.

Ibanjirije iyi: Umuyoboro w'amazi uzungurutse

Ibikurikira: Umuyoboro w'umurongo wa API 5L udafite umugozi kandi uhujwe

Andika ubutumwa bwawe hano hanyuma ubwoherereze
