Valve y'Irembo ry'Icyuma Cyakozwe mu Cyuma Gikozwe mu Cyuma Gifite Impera Ifite Ibara
✧ Ibisobanuro
Amavali y'irembo ry'icyuma acuzwe akunze gukoreshwa mu nganda bitewe n'uko yubatswe neza kandi akabasha kwihanganira umuvuduko mwinshi n'ubushyuhe. Akenshi akunze gukoreshwa mu nganda za peteroli na gaze, inganda z'amashanyarazi, n'inganda zikora peteroli. Dore bimwe mu bintu by'ingenzi n'ibyiza bya vali z'irembo ry'icyuma zicuzwe: Akomeye kandi Aramba: Amavali y'irembo ry'icyuma acuzwe akorwa hakoreshejwe uburyo bwo gucukura, butuma akomeye cyane kandi arwanya imihangayiko ya mekanike. Ibi bituma aba akwiriye ahantu hakomeye aho kuramba ari ingenzi. Kurwanya umuvuduko mwinshi n'ubushyuhe: Izi vali zagenewe guhangana n'umuvuduko mwinshi n'ubushyuhe bwinshi, zitanga igisubizo cyizewe cyo kugenzura amazi mu bihe bigoye. Imiterere myiza yo gufunga: Atanga imiterere myiza yo gufunga, akarinda gusohoka mu gihe vali ifunze. Ibi ni ingenzi cyane mu kubungabunga ubuziranenge bw'imikorere no gukumira gutakaza amazi. Gutakaza umuvuduko muke: Iyo ifunguye neza, imvange z'icyuma zikozwe mu buryo bwa "forged gate" zitanga igihombo gito, bigatuma habaho uburyo bwo kugenzura neza amazi no kugabanya ikoreshwa ry'ingufu. Guhindagurika: Zikwiriye ubwoko bwinshi bw'amazi, bigatuma zikoreshwa mu buryo butandukanye mu nganda. Gukurikiza amahame ngenderwaho: Imvange z'icyuma zikozwe mu buryo bwa "forged gate" akenshi zikorwa kandi zigakorwa hakurikijwe amahame ngenderwaho mu nganda, zigatuma zizewe kandi zikora neza. Muri rusange, imvange z'icyuma zikozwe mu buryo bwa "forged gate" zihabwa agaciro kubera imbaraga zazo, kuramba kwazo, kudatakaza umuvuduko mwinshi n'ubushyuhe, imiterere myiza yo kuzifunga, no gukoresha ibintu byinshi bitandukanye, bigatuma ziba amahitamo meza mu nganda zikenera cyane.
✧ Ibiranga valve y'icyuma ikoze muri API 602
1.Inyubako yayo yoroshye kurusha valve y'irembo, kandi yoroshye kuyikora no kuyibungabunga.
2.Ubuso bwo gufunga ntabwo bworoshye kwambara no gushwanyaguza, kandi ubushobozi bwo gufunga ni bwiza. Nta kintu na kimwe kigenda hagati ya disiki ya valve n'ubuso bwo gufunga bw'umubiri wa valve iyo ufunguye cyangwa ufunga, bityo gushwanyaguza no gushwanyaguza ntibikomeye, ubushobozi bwo gufunga ni bwiza, kandi igihe cyo kuyikoresha ni kirekire.
3.Mu gufungura no gufunga, umurongo wa disiki uba muto, bityo uburebure bwa valve yo guhagarika ni buto ugereranije n'ubw'irembo, ariko uburebure bw'imiterere ni burebure ugereranyije n'ubw'irembo.
4.Umuvuduko wo gufungura no gufunga ni munini, gufungura no gufunga biragoye, kandi igihe cyo gufungura no gufunga ni kirekire.
5. Ubudahangarwa bw'amazi ni bwinshi, kuko umuyoboro uri hagati mu gice cy'umubiri wa valve urimo guhindagurika, ubudahangarwa bw'amazi ni bwinshi, kandi ingufu zikoreshwa ni nyinshi.
6. Icyerekezo cy'umuvuduko uri hagati Iyo umuvuduko wa nominel PN ≤ 16MPa, muri rusange ifata umuvuduko ugana imbere, naho umuvuduko ugana hejuru uturutse hasi kuri disiki ya valve; iyo umuvuduko wa nominel PN ≥ 20MPa, muri rusange ifata umuvuduko ugana inyuma, naho umuvuduko ugana hasi uturutse hejuru kuri disiki ya valve. Kugira ngo wongere imikorere ya seal. Iyo ikoreshwa, umuvuduko wa valve ugana hejuru ushobora gutembera mu cyerekezo kimwe gusa, kandi icyerekezo cy'umuvuduko ntigishobora guhindurwa.
7.Disiki ikunze kwangirika iyo ifunguye neza.
✧ Ibyiza bya API 602 forged steel gate valve
Mu gihe cyo gufungura no gufunga valve y'icyuma gikozwe mu cyuma, kubera ko ubushyuhe buri hagati ya disiki n'ubuso bw'inyuma bw'umubiri wa valve ari buto ugereranije n'ubw'inyuma, ntabwo iramba.
Uburyo bwo gufungura cyangwa gufunga igice cy'umugozi wa valve ni bugufi cyane, kandi bufite imikorere yizewe yo gukata, kandi kubera ko guhindura aho intebe y'umugozi ihurira bingana n'uburyo icyuma gifata disiki ya valve, birakwiriye cyane mu guhindura umuvuduko w'amazi. Kubwibyo, ubu bwoko bwa valve burakwiriye cyane mu gukata cyangwa kugenzura no gufunga.

✧ Serivisi nyuma yo kugurisha
Nk'umwuga mu gukora no kohereza hanze valve z'icyuma zikozwe mu bucuzi, dusezeranya guha abakiriya serivisi nziza nyuma yo kugurisha, harimo ibi bikurikira:
1. Gutanga amabwiriza yo gukoresha ibicuruzwa n'ibitekerezo ku bijyanye no kubungabunga.
2. Ku bibazo byatewe n'ubuziranenge bw'ibicuruzwa, twizeza gutanga ubufasha bwa tekiniki no gukemura ibibazo mu gihe gito gishoboka.
3. Uretse ibyangiritse bitewe n'ikoreshwa risanzwe, dutanga serivisi zo gusana no gusimbuza ku buntu.
4.Turasezeranya gusubiza vuba ibyifuzo by'abakiriya mu gihe cy'ingwate y'ibicuruzwa.
5. Dutanga ubufasha bw'igihe kirekire mu bya tekiniki, serivisi zo gutanga inama no guhugura kuri interineti. Intego yacu ni uguha abakiriya serivisi nziza no gutuma uburambe bw'abakiriya burushaho kuba bwiza kandi bworoshye.
