Valve njengethuluzi sekutalwe iminyaka letinkhulungwane .

I valvelithulusi lelisetjentiswa ekudluliseleni nasekulawuleni igesi kanye neliketjezi lokungenani leminyaka leyinkhulungwane yemlandvo.

Kwanyalo, eluhlelweni lwemaphayiphi emanti, i-valve lecondzisako yintfo yekulawula, futsi umsebenti wayo lomkhulu kuhlukanisa imishini kanye neluhlelo lwemaphayiphi, kulawula kugeleta, kuvikela kugeleta emuva, kulawula kanye nekukhipha umfutfo. Njengoba kubaluleke kakhulu kukhetsa ivalve lefanele kakhulu yekulawula yeluhlelo lwemaphayiphi, kuphindze kubaluleke kakhulu kuvisisa timphawu tevalve kanye netinyatselo kanye nesisekelo sekukhetsa ivalve.

Umfutfo wevalvi

Umfutfo lobitwako wevalve ubhekisela umklamo loniketwe umfutfo lohlobene nemandla emishini yetincenye temaphayiphi, lokusho kutsi, ngumfutfo lovumelekile wekusebenta wevalve ngesikhatsi sekushisa lesicacisiwe, lokuhlobene netintfo tevalve. Umfutfo wekusebenta awufani, ngako-ke, umfutfo weligama uyipharamitha lencike etintfweni tevalve futsi ihlobene nekushisa lokuvumelekile lokusebenta kanye nemfutfo wekusebenta walentfo.

Ivalve yintfo leseluhlelo lwekujikeleta lolusemkhatsini noma luhlelo lwekucindzetela, lolusetjentiselwa kulungisa kugeleta noma kucindzetela kwemkhatsi. Leminye imisebenti ifaka ekhatsi kuvala noma kuvula imidiya, kulawula kugeleta, kushintja indlela yekugeleta kwemidiya, kuvikela kubuyela emuva kwemidiya, kanye nekulawula noma kukhipha umfutfo.

Lemisebenti izuzwa ngekulungisa isikhundla valve kuvalwa. Loku kulungisa kungentiwa ngesandla nobe ngekuzenzakalela. Kusebenta ngesandla kuphindze kufake kusebenta kwekulawula idrayivu ngesandla. Emavalvu lasebenta ngesandla abitwa ngekutsi ngemavalvu lasebenta ngesandla. I-valve levimbela kugeleta emuva ibitwa ngekutsi yi-valve yekuhlola; leyo lelawula umfutfo wekukhululeka ibitwa ngekutsi yivalve yekuphepha noma ivalve yekukhululeka yekuphepha.

Kuze kube manje, imboni yevalve ikhonile kukhicita uhla lolugcwele lwe .emavalvu esango, emavalvu e-globe, emavalvu e-throttle, emavalvu epulagi, emavalvu ebhola, emavalvu agezi, emavalvu ekulawula i-diaphragm, emavalvu ekuhlola, emavalvu ekuphepha, emavalvu ekunciphisa umfutfo, ticupho temfutfo kanye nemavalvu ekuvala ngesikhatsi lesiphutfumako. Valve imikhicito 12 tigaba, ngetulu 3000 imifuziselo, kanye ngetulu 4000 ukucaciswa; umfutfo lomkhulu wekusebenta ngu-600MPa, ububanzi lobukhulu lobubitwako ngu-5350mm, lokushisa lokusezingeni leliphakeme lokusebenta ngu-1200 .°C, lokushisa lokuncane lokusebenta ngu -196 .°C, futsi indlela lesebentako yiManti, umfutfo, oyili, igesi yemvelo, indlela lecinile yekubola (njenge nitric acid lecinile, i-sulfuric acid lesemkhatsini, njll).

Naka kukhetsa kwevalve:

1. Kute kuncishiswe kujula kwemhlabatsi lombonya liphayiphi,ivalvi yevivaneivame kukhetfwa iphayiphi lenkhulu lenebubanti; lokubi lokukhulu kwe valve ye butterfly kutsi ipuleti le butterfly litsatsa sigaba lesitsite sesiphambano semanti, lokukhulisa kulahlekelwa kwenhloko letsite;

2. Emavalvu lavamile afaka ekhatsi .emavalvu evivane, emavalvu esango, emavalvu ebhola kanye nemavalvu epulagi, njll Libanga lemavalvu lasetjentiswa kunethiwekhi yekuniketa emanti kumele licatjangelwe ekukhetseni.

3. Kulahlwa kanye nekucubungula emavalvu ebhola kanye nemavalvu epulagi kumatima futsi kuyabiza, futsi kuvame kulungele emaphayiphi lamancane nalasemkhatsini. Ball valve kanye ne plug valve kugcina tinzuzo valve lisango linye, emanti lamancane kugeleza ukumelana, kuvala letsembekile, sento lokugucugucuka, kusebenta elula kanye nekunakekelwa. I-valve yepulagi nayo inetinzuzo letifanako, kepha sigaba sekudlula emanti akusiyo umbuthano lophelele.

4. Uma kunemphumela lomncane ekujuleni kwemhlabatsi lovalako, zama kukhetsa ivalve yesango; kuphakama kwevalve yesango legezi ivalve yesango lemile lenebubanti lobukhulu ithinta kujula lokumbonya umhlabatsi kweliphayiphi, futsi budze bevalve yesango levundlile lenebubanti lobukhulu bukhulisa indzawo levundlile lehlalwa liphayiphi futsi butsintsa kuhleleka kwalamanye emaphayiphi ;

5. Eminyakeni yamuva, ngenca yekutfutfuka kwebuchwepheshe bekulahla, kusetjentiswa kwekulahla sihlabatsi se-resin kungagwema noma kunciphise kucubungula ngemishini, ngaleyo ndlela kunciphise tindleko, ngako-ke kungenteka kwemavalvu ebhola lasetjentiswa kumaphayiphi lamakhulu-diameter kufanelekile kuhlola. Njengobe umugca umkhawulo caliber usayizi, kufanele kucatshangelwe bese uhlukaniswe ngokuya isimo ethile.
