Amakuru - Ni bande batanga amashanyarazi 10 ya Shutdown Valve ku isi?

Abatanga serivisi 10 za mbere zo gufunga valve barimo ibigo bizwi bikurikira

Emerson, muri Amerika:

Ikirango cya Fisher kiri munsi ya Emerson cyibanda ku miyoboro igenzura ibikorwa, ikoreshwa cyane muri peteroli, gaze, imiti n'ibindi.

Schlumberger, muri Amerika:

Cameron uyobowe na Schlumberger atanga ibikoresho byo mu bwoko bwa valves n'ibikoresho byo mu ruganda rwa peteroli na gaze.

Flowserve, muri Amerika:

Itanga ubwoko butandukanye bw'amavali yo mu nganda, harimo amavali yo kugenzura, amavali y'umupira, amavali y'ibinyugunyugu, n'ibindi, bikorera inganda zitunganya ingufu, imiti n'amazi.

Tyco International, muri Amerika:

Ikirango cyayo cya Tyco Valves & Controls gitanga valves zo kurinda inkongi, ibikorwa byo mu nganda no mu bucuruzi.

KITZ, Ubuyapani:

Imwe mu nganda nini zikora valve mu Buyapani, ifite ibicuruzwa bikubiyemo inganda, ubwubatsi n'ibikorwa bya gisivili.

IMI, Ubwongereza:

IMI Critical Engineering yibanda ku nganda zigezweho, zikorera inganda zikora ingufu, ingufu n'ibinyabutabire.

Crane, muri Amerika:

Ikirango cyayo cyitwa Crane ChemPharma & Energy gitanga ibisubizo by'uturindantoki ku nganda zikora imiti, peteroli n'ingufu.

Velan, Kanada:

Yibanda ku mavali y'inganda, harimo amavali y'irembo, amavali y'umupira, amavali y'ibinyugunyugu, n'ibindi.

KSB, Ubudage:

Itanga ibisubizo bya pompe na valve, bikoreshwa cyane mu gutunganya amazi, ingufu n'inganda.

Itsinda rya Weir, mu Bwongereza:

Ikirango cyayo cya Weir Valves & Controls cyibanda ku mavali akora neza cyane mu bucukuzi bw'amabuye y'agaciro, amashanyarazi n'inganda za peteroli na gaze.

Inama:NUruganda rwa SW Valveni ikigo kizwi cyane gitanga serivisi zo gufunga amavali mu Bushinwa. Bafite uruganda rwabo bwite rukora ibikoresho byo gufunga amavali n'uruganda rukora ibikoresho byo gufunga amavali. Bashobora kuguha ubufasha bw'umwuga mu bya tekiniki n'ibiciro by'uruganda rukora ibikoresho byo gufunga amavali.

Valve yo kuzimya (SDV)

Valve yo kuzimya (SDV) ni iki?

Valve yo kuzimya ni ubwoko bwa actuator muri sisitemu yo kwikora. Igizwe na actuator ya diaphragm ifite umuyaga mwinshi cyangwa actuator ya piston igenda n'actuator igenzura. Ikoreshwa cyane cyane mu guca cyangwa guhuza amazi mu muyoboro vuba (nk'umwuka, umwuka utwika, umwuka ukonje na gaze y'amazi, nibindi). Ikoreshwa cyane mu buryo bwo kugenzura umutekano mu nganda no mu guhangana n'impanuka zihutirwa.

Imikorere y'ingenzi n'amahame y'imikorere ya Valve yo kuzimya

Akamaro k'ingenzi ka valve yo kuzimya ni uguca vuba, guhuza cyangwa guhindura amazi ari mu muyoboro wifashishije ikimenyetso cy'igikoresho kiwugenzura (nk'umuvuduko w'amashanyarazi, ubushyuhe cyangwa inzogera yo gusohora amazi). Imikorere yayo isanzwe ikubiyemo:

Itera ry'ibimenyetso:Iyo sensor ibonye ikintu kidasanzwe (nk'ibyuka biva, umuvuduko urenze urugero), ikimenyetso cyoherezwa kuri actuator.

Igisubizo cya tekiniki:Diaphragm cyangwa uburyo bwa piston butuma igice cy'umubiri wa valve kigenda (nk'imvange y'umupira, valavu y'intebe imwe), bigahindura imiterere y'ifungura n'ifunga rya valve.

Urufunguzo rw'umutekano:Nyuma y'uko valve yo gufunga byihutirwa ifunzwe, akenshi iba igenewe kuba iri mu buryo bwo kwifunga ubwayo kugira ngo hirindwe ko ifungurwa ku bw'impanuka.

Ubwoko bw'ingenzi n'ingero z'ikoreshwa rya valve yo kuzimya

Vali zo kuzimyabishobora kugabanywamo ubwoko bukurikira busanzwe bitewe n'imiterere n'icyo bugamije:

‌Valves zisanzwe zo gufunga:ikoreshwa mu kugenzura ibikorwa by'inganda (nk'inganda zikora imiti n'ibyuma), ahanini ikoresha icyuma gikingira imipira cyangwa imiterere y'icyuma gikingira imipira kugira ngo hagerwe ku buryo buciriritse bwo kuyihagarika.

Valve yo gufunga byihutirwa:byibanze ku buryo bw'umutekano (nk'imiyoboro ya gazi na sisitemu za SIS), hamwe n'umuvuduko wihuse wo gusubiza no kwifunga kugira ngo hirindwe ko impanuka zaguka.

Valve yo kuzimya diyafrog ya pneumatic:Valve igenzurwa na diaphragm itwarwa n'umuvuduko w'umwuka, ikwiriye gukoreshwa mu kugenzura imikorere y'ikoranabuhanga (nk'inganda zikora peteroli n'ingufu).
