Valve nk'igikoresho imaze imyaka ibihumbi ivutse

Valveni igikoresho gikoreshwa mu kohereza no kugenzura gazi n'amazi gifite nibura amateka y'imyaka igihumbi.

Muri iki gihe, muri sisitemu y'imiyoboro y'amazi, valve igenzura ni yo igenzura, kandi inshingano yayo nyamukuru ni ugutandukanya ibikoresho n'imiyoboro, kugenzura amazi atemba, gukumira gusubira inyuma kw'amazi, kugenzura no gusohora umuvuduko. Kubera ko ari ingenzi cyane guhitamo valve igenzura ikwiriye sisitemu y'imiyoboro, ni ingenzi cyane gusobanukirwa imiterere y'iyi valve n'intambwe n'ishingiro ryo guhitamo valve.

Igitutu cy'agace k'ingufu

Igitutu cy’umuvuduko w’imvange yerekeza ku gitutu cyatanzwe kijyanye n’imbaraga za mekanike z’ibice by’imiyoboro, ni ukuvuga ko ari igitutu cyemewe cy’imvange ku bushyuhe bwagenwe, kijyanye n’ibikoresho bya vange. Igitutu cy’umuvuduko w’umuvuduko ntabwo ari kimwe, bityo, igitutu cy’umuvuduko ni igipimo gishingiye ku bikoresho bya vange kandi kijyanye n’ubushyuhe bwemewe bw’umuvuduko w ...

Valve ni igikoresho kiri muri sisitemu yo kuzenguruka cyangwa sisitemu yo gushyushya, gikoreshwa mu guhindura uburyo umwuka utembera cyangwa umuvuduko w'umwuka. Izindi nshingano zirimo kuzimya cyangwa gucana ibyuma, kugenzura uburyo umwuka utembera, guhindura icyerekezo cy'uburyo umwuka utembera, gukumira ko umwuka usubira inyuma, no kugenzura cyangwa gusohora umwuka.

Iyi mirimo igerwaho binyuze mu guhindura aho valve ifunga. Uku guhindura bishobora gukorwa n'intoki cyangwa mu buryo bwikora. Umurimo wo gukoresha intoki ukubiyemo no kugenzura intoki. Valve zikoreshwa n'intoki zitwa valve zikoreshwa n'intoki. Valve ibuza gusubira inyuma yitwa valve yo kugenzura; iyo igenzura umuvuduko wo gutabara yitwa valve y'umutekano cyangwa valve yo gutabara umutekano.

Kugeza ubu, inganda zikora valve zashoboye gukora ubwoko bwose bwavalve zo mu irembo, valve z'isi, valve zo kugosora, valve zo kuziba, valve z'umupira, valve z'amashanyarazi, valve zo kugenzura diaphragm, valve zo kugenzura, valve z'umutekano, valve zigabanya umuvuduko, imitego y'umwuka n' valve zo kuzimya byihutirwa. Ibikoresho bya valve by'ibyiciro 12, moderi zirenga 3000, n'ibipimo birenga 4000; umuvuduko ntarengwa wo gukora ni 600MPa, umurambararo ntarengwa ni 5350mm, ubushyuhe ntarengwa bwo gukora ni 1200℃, ubushyuhe buke bwo gukora ni -196℃, kandi uburyo bukoreshwa ni Amazi, umwuka w'umwuka, peteroli, gazi karemano, ibikoresho bikomeye byangiza (nk'aside nitrike yikubise, aside sulfure iringaniye, nibindi).

Witondere guhitamo valve:

1. Kugira ngo ugabanye uburebure bw'ubutaka butwikiriye umuyoboro,agace k'ikinyugunyugumuri rusange itoranywa mu muyoboro munini w'umurambararo; ikibazo gikomeye cya valve y'ikinyugunyugu ni uko icyuma cy'ikinyugunyugu gifata igice runaka cy'amazi, ibyo bikaba byongera igihombo runaka ku mutwe;

2. Utwuma dusanzwe tugizwevalve z'ibinyugunyugu, valve zo mu irembo, vali z'umupira n'amavali yo kuziba, n'ibindi. Ubwoko bw'amavali akoreshwa mu miyoboro y'amazi bugomba kwitabwaho mu guhitamo.

3. Gutunganya no gutunganya valves z'umupira n'ama-plugs biragoye kandi birahenze, kandi muri rusange bikwiranye n'imiyoboro mito n'iciriritse. Valve y'umupira n'ama-plugs bikomeza ibyiza bya valve imwe y'irembo, kudakora amazi menshi, gufunga neza, gukora neza, gukora no kubungabunga byoroshye. Valve y'ama-plugs nayo ifite ibyiza bisa, ariko igice cyo kunyuramo amazi si uruziga rwiza.

4. Niba ntacyo bitwaye cyane ku bujyakuzimu bw'ubutaka butwikiriye, gerageza guhitamo valve y'irembo; uburebure bwa valve y'irembo y'amashanyarazi valve nini y'irembo ihagaze igira ingaruka ku bujyakuzimu bw'umuyoboro utwikiriye ubutaka, kandi uburebure bwa valve nini y'irembo ihagaze yongera ubuso butambitse bwinjizwa n'umuyoboro kandi bukagira ingaruka ku miterere y'indi miyoboro;

5. Mu myaka ya vuba aha, bitewe n’iterambere ry’ikoranabuhanga ryo gucukura, ikoreshwa rya resin casting rishobora kwirinda cyangwa kugabanya itunganywa ry’imashini, bityo bikagabanya ikiguzi, bityo rero ubushobozi bwo gukoresha valves z’umupira zikoreshwa mu miyoboro minini bukwiye gusuzumwa. Ku bijyanye n’umurongo w’ingano y’imbibi, ugomba gusuzumwa no kugabanywa hakurikijwe uko ibintu bimeze.
