DN50-300 Emavalvu lakhipha umoya ngesivinini lesikhulu lahlanganisiwe eKulahleni Insimbi Lecinile GGG40 , PN10/16

Wonkhe lilunga lelivela ecenjini letfu lelikhulu lenzuzo yekusebenta kahle liyatitsatsa njengaletiligugu tidzingo temakhasimende kanye nekuchumana kwenhlangano ye-2019 intsengo ye-wholesale ductile ironIvalvu Yekukhipha Umoya, Kutfolakala lokuchubekako kwetisombululo telizinga leliphakeme ngekuhlanganiswa netinsita tetfu letinhle kakhulu tekucala nangemuva kwekutsengisa kucinisekisa kuncintisana lokucinile endzaweni yemakethe lekhulako yemhlaba wonkhe.
Wonkhe lilunga lelivela ecenjini letfu lelikhulu lenzuzo yekusebenta kahle liyatitsatsa njengaletiligugu tidzingo temakhasimende kanye nekuchumana kwenhlangano kweIvalvu Yekukhipha Umoya, Sitfole win ludvumo loluhle emkhatsini wemakhasimende langesheya kwetilwandle nasekhaya. Ngekunamatsela emfundzisweni yekulawula yekutsi “kugcila esikweletini, emakhasimende kucala, kusebenta kahle lokusezingeni leliphakeme kanye netinsita letivutsiwe”, semukela ngemfutfo bangani labavela kuto tonkhe tigaba temphilo kutsi babambisane natsi.

Incazelo:

Le valve yekukhipha umoya ngesivinini lesikhulu lehlanganisiwe ihlanganiswe netincenye letimbili te-valve yemoya ye-diaphragm lephakeme kanye nekucindzeteleka lokuphansi kwekungena kanye nevalve yekukhipha ,Inemisebenti yekukhipha kanye nekutsatsa.
I-valve yekukhipha umoya we-diaphragm lenemandla lamakhulu iyakhipha ngekuzenzakalela umoya lomncane lobutfwe kulephayiphi uma leliphayiphi lingaphansi kwemfutfo.
Le low-pressure intake kanye ne exhaust valve ayikhoni kuphela kukhipha umoya ephayiphini uma liphayiphi lelite lutfo ligcwele emanti, kepha futsi uma liphayiphi lingagcwaliswa noma kucindzeteleka lokubi kwenteka, njengangaphansi kwesimo sekuhlukana kwekholomu yemanti, kutawuvuleka ngekuzenzakalela bese kungena ephayiphini kucindzetela lokubi.

Lomunye wemisebenti lebalulekile ye-vent valve kukhipha umoya lovalelekile kuloluhlelo. Nangabe lutfuli lungena emaphayiphini, umoya ungavaleleka etindzaweni letiphakeme, njengekugoba, tindzawo letiphakeme, kanye netihloko tetintsaba. Njengoba lutfuli lugeleta ngemaphayiphi, umoya ungagcwala bese wakha emaphakethe emoya, lokungaholela ekuncipheni kwekusebenta kahle kanye nekukhuphuka kwemfutfo.

Emavalvu lakhipha umoya, njengalamanye e-TWS Valveemavalvu lahlala ngerabha, futsi badlale indzima lebalulekile ekugcineni kusebenta kahle kanye nekusebenta kahle kwemaphayiphi netinhlelo letitfwala tintfo letimanti. Likhono labo lekukhipha umoya lovalelekile kanye nekuvikela timo te vacuum kucinisekisa kusebenta kahle kweluhlelo, kuvikela kuphazamiseka kanye nekulimala. Ngekuvisisa kubaluleka kwemavalvu ekukhipha umoya kanye nekutsatsa tinyatselo letifanele tekufaka kanye nekunakekela, basebentisi beluhlelo bangacinisekisa kuphila sikhatsi lesidze kanye nekwetsembeka kwemapayipi abo kanye netinhlelo.

Tidzingo tekusebenta:

Low pressure umoya release valve (float + float type) itheku lelikhulu lekukhipha umoya licinisekisa kutsi umoya ungena futsi uphuma ngesilinganiso lesiphakeme sekugeleta ngesivinini lesikhulu lesikhishwa ngumoya, ngisho nemoya lohamba ngesivinini lesikhulu lohlanganiswe nenkungu yemanti,Ngeke uvale itheku lekukhipha umsindvo ku adva. kukhishwa ngalokuphelele.
Noma ngabe ngusiphi sikhatsi, uma nje umfutfo wangekhatsi waleluhlelo ungaphansi kwemfutfo wemkhatsi, sibonelo, uma kwehlukaniswa kwekholomu yemanti kwenteka, ivalve yemoya itawuvele ivule umoya ungene kulenchubo kuvikela kukhicitwa kwe vacuum kulenchubo. Ngesikhatsi lesifanako, kutsatsa umoya ngesikhatsi uma lendlela ikhipha kungasheshisa sivinini sekukhipha. Letulu kwevalve yekukhipha ifakwe ipuleti lelilwa nekutfukutsela kwentela kushelela inchubo yekukhipha, lekungavikela kugucugucuka kwemfutfo noma letinye tintfo letibhubhisako.
Le valve yekukhipha umfutfo lomkhulu yekulandzelela ingakhipha umoya lobutfwe etindzaweni letisetulu kuloluhlelo ngesikhatsi lapho khona loluhlelo lungaphansi kwemfutfo kugwema letintfo letilandzelako letingabangela kulimala kuloluhlelo: kukhiya umoya noma kuvimba umoya.
Kukhulisa kulahleka kwenhloko yalendlela kunciphisa lizinga lekugeleta futsi ngisho nasetimeni letimbi kakhulu kungaholela ekuphazamisekeni lokuphelele kwekuletsa emanti. Kucinisa umonakalo we-cavitation, kusheshisa kugcola kwetincenye tensimbi, kukhulisa kugucugucuka kwemfutfo eluhlelweni, kukhulisa emaphutsa emishini yekulinganisa, kanye nekuqhuma kwegesi. Nconota kusebenta kahle kwekuniketwa kwemanti kwekusebenta kwemaphayiphi.

Umtsetfo wekusebenta:

Inchubo yekusebenta yevalve yemoya lehlanganisiwe uma liphayiphi lelite lutfo ligcwele emanti:
1. Dlulisa umoya ephayiphini kwenta kutsi kugcwaliswa kwemanti kuchubeke kahle.
2. Ngemuva kwekutsi umoya losephayiphini sewuphelile, emanti angena ku-valve lephansi yekutsatsa kanye nekukhipha, bese kuntanta kuphakanyiswa yi-buoyancy kuvala emachweba ekutsatsa nekukhipha.
3. Umoya lokhishwa emantini ngesikhatsi senchubo yekuletsa emanti utawubutfwa endzaweni lephakeme yeluhlelo, lokusho kutsi, ku-valve yemoya kute kutsatfwe sikhundla semanti ekucala emtimbeni wevalve.
.
5. Ngemuva kwekutsi umoya sewukhululiwe, emanti angena ku-valve yekukhipha umoya lencane lenemfutfo lomkhulu futsi, antanta ibhola lelintantako, bese avala umnyango wekukhipha umoya.
Uma luhlelo lusebenta, letinyatselo letingenhla letingu-3, ​​4, 5 titawuchubeka tijikeleta .
Inchubo yekusebenta yevalve yemoya lehlanganisiwe uma umfutfo kuloluhlelo ungumfutfo lophansi kanye nemfutfo wemkhatsi (lokhicita umfutfo longakalungi):
1. Ibhola lelintantako le-valve yekutsatsa kanye nekukhipha umfutfo lophansi litawuwela ngekushesha kute livule emachweba ekutsatsa kanye nekukhipha.
2. Umoya ungena eluhlelweni kusuka kuleliphuzu kucedza umfutfo lomubi kanye nekuvikela leluhlelo.

Tilinganiso:

Njalo lilunga linye kusuka ecenjini letfu lelikhulu lenzuzo yekusebenta kahle liyatitsatsa njengaletibalulekile tidzingo temakhasimende kanye nekuchumana kwenhlangano ye-2019 intengo ye-wholesale ductile iron Air Release Valve, Kutfolakala lokuchubekako kwetisombululo letisezingeni lelisetulu ngekuhlanganiswa netinsita tetfu letinhle kakhulu ngaphambi kwekutsengisa nangemuva kwekutsengisa kucinisekisa kucudzelana lokucinile endzaweni lekhulako yemhlaba wonkhe.
