Ngokwesibonelo, cabangela ithangi elikhulu elinesivalo. Amanzi angena ethangini aphinde aphume ekhanda lesilinda. Ikhanda lesilinda lisebenza njengengxenye yokuvala yevalvu. Uma isandla sikhuphukela ekhanda le-cylinder, lilingana nomgomo wokusebenza we-valve yokumisa. Uma uhambisa ikhanda le-cylinder nxazonke, lisebenza ngendlela efanayo ne-valve yokumisa.

Ukucaciswa okubalulekile:
1. Ukucaciswa kwedizayini: GB/T 12235
2. Imininingwane yokuxhumana:
1) I-BW ye-butt welding end: cindezela i-GB/T 12224
2) I-Flange end RF: cindezela i-JB79; I-GB/T 9113; HG20592
3, ukutholwa kwe-valve nokuhlola :GB/T 13927; I-JB/T 9092
Sebenzisa ukwakhiwa okulandelayo:
Vula uhlobo lohlaka losekelo lwebha
Isikulufa esixhunywe i-valve eyodwa yokugeleza; I-gas pressure iqinisa i-valve yokugeleza eyodwa
Isihlalo esisodwa sokuvala esingaphezulu

Izingxenye ezivulayo nezivalayo zevalvu yembulunga ziyi-cylindrical disc, kanti i-protruder surface iplani noma iyindilinga. I-valve disc ihamba ngokufanayo eduze kwe-axis ewuketshezi ngomugqa oqondile. Imodi yokunyakaza yesiqu se-valve, kukhona uhlobo lwenduku yokusunduza kagesi (ukulungiswa kwe-valve stem, ukuphotha akulungisi), nokulungisa uhlobo lwenduku ejikelezayo (ukuphakamisa ukujikeleza kwe-valve stem, ibhawodi elakhiwe epuleti likawoyela). I-valve ye-globe ingeyokuvula nokuvala kuphela, eyenziwe ngokwezifiso ingashintshwa kanye ne-throttle valve.
Lapho i-valve yembulunga ivuliwe, ukuphakama okuhlobene kokuvula i-disc kungu-25% ~ 30% we-diameter yangaphandle, ukugeleza okuphelele kufinyelele endaweni enkulu kakhulu, okubonisa ukuthi i-valve ibe ngaphezu kokuvuleka ngokugcwele. Ngakho-ke, isikhundla esigcwele esivulekile se-valve yomhlaba kufanele sinqunywe yi-disc stroke.
Amathiphu evalvu: Akufundisa ukuhlonza ikhwalithi yevalvu uvemvane kanye nezinto ezivamile zokuvala izivalo zamavalvu embulunga yonke kanye nezinga layo lokuvuza lokuvala amapharamitha ayinhloko okuhlonza izinga lenani lenkomba levalvu. I-valve ayilungile noma ayimbi, i-valve yesicelo sesimo sokusebenza esiyingqayizivele ingasetshenziswa isikhathi eside futhi ingasetshenziswa isikhathi esifushane kakhulu. Ngakho ungahluleli ngokufaneleka. Kuya ngenhlanganisela yezimo zokusebenza. I-valve yeglobu ye-plunger: Ngale ndlela i-valve yembulunga iwukuhluka kwe-valve yeglobhu eyisisekelo. Kule valve, i-disc kanye nama-valve amasango omfutho ophezulu ngokuvamile enziwa ngokwezifiso ngokusho kwe-plunger rationale. I-disc ipholishwa ibe yi-plunger futhi ixhunywe esiqwini. Uphawu lutholakala ngezindandatho ezimbili ze-elastomer ezimuncelwe ku-plunger.
Thola ikhwalithi yevalve uvemvane
Ukuqina kwe-valve ukuhlola i-valve. Ingakwazi ukufeza ukubekwa uphawu okuphelele kakhulu kuncike ezintweni ze-valve, inqubo yokukhiqiza, inqubo yokukhiqiza kanye nesimo sokusebenza esisetshenzisiwe.
Izinto zokuvala ze-valve nezinga layo lokuvuza lokuvala yimingcele eyinhloko yenani lenkomba yokuhlonza ukuphakama kwe-valve. I-valve ayilungile noma ayimbi, i-valve yesicelo sesimo sokusebenza esiyingqayizivele ingasetshenziswa isikhathi eside futhi ingasetshenziswa isikhathi esifushane kakhulu. Ngakho ungahluleli ngokufaneleka. Kuya ngenhlanganisela yezimo zokusebenza.
I-valve uvemvane evula futhi evala ingxenye ipuleti uvemvane okumise okwediski, elizungeza umugqa walo oyingqayizivele omaphakathi emzimbeni wevalvu ukuze uvule futhi uvale noma ulungise i-valve ebizwa ngokuthi i-butterfly valve. I-valve uvemvane ngokuvamile ingaphansi kwamadigri angu-90 ukusuka ekuvuleni kuya ekuvaleni. I-valve yovemvane kanye nenduku yovemvane azikhiyiwe ngokuqinile. Ukuze ubeke ipuleti levemvane, kufanele kufakwe isinciphisi seplanethi esiqwini se-valve. Ukukhethwa kwe-reducer yeplanethi, akugcini nje ukwenza ipuleti ye-butterfly ngezinga lokukhiya, ukuze ipuleti ye-butterfly iphele endaweni engahleliwe, kodwa futhi ingathuthukisa izici zokusebenza ze-valve.
Izici ze-valve ye-butterfly yokukhiqiza izimboni zingamelana nokushisa, isigaba sokucindezela esitholakalayo sokusebenza siphezulu kakhulu, ububanzi obujwayelekile be-valve bukhulu, i-valve ye-solenoid yenziwa nge-carbon steel, i-valve plate yokuvala indandatho yenziwe ngensimbi esikhundleni indandatho yerabha. Amavalvu ovemvane amakhulu namasayizi amaphakathi aqhubekayo akhiwa ngamapuleti ensimbi ashiselayo, asetshenziswa kakhulu emhubheni wentuthu ophakathi nendawo nokushisa okuqhubekayo.
Izinhlobo zama-valve embulunga ezivamile
1, I-Angle globe valve ku-Angle globe valve, uketshezi ludinga kuphela ukushintsha umumo kanye, ukuze umfutho wegesi ngevalvu ube mncane kunesakhiwo esiyisisekelo se-valve yembulunga.
I-2, i-valve yeglobu yohlobo lwe-DC ekugelezeni okuqondile kanye ne-valve yembulunga emise okuka-Y, isango lepuleti lesiteshi sikawoyela kanye nendlela enkulu yokugeleza ingene kusihlibhi, izinga lokugeleza liphansi kune-valve yembulunga eyisisekelo, ngakho-ke ngokusho kwevalve ye-bamboo Ze ukumelana nokugeleza nakho kuhambisana nokuncane.
I-3, i-valve yeglobhu yohlobo lwe-plunger: le ndlela yevalvu yembulunga iwukuwohloka kwe-valve yembulunga eyisisekelo. Kule valve, i-disc kanye nama-valve amasango omfutho ophezulu ngokuvamile enziwa ngokwezifiso ngokusho kwe-plunger rationale. I-disc ipholishwa ibe yi-plunger futhi ixhunywe esiqwini. Uphawu lutholakala ngezindandatho ezimbili ze-elastomer ezimuncelwe ku-plunger. Izigxivizo ezimbili ze-elastomeric zihlukaniswa yi-clasp futhi zihlanganiswe eduze kwe-plunger ngomthwalo owengezwe ku-valve eyodwa yokugeleza ngamantongomane e-valve yokugeleza eyodwa. Ama-Elastoseal ayasuswa futhi angenziwa ngezinto ezihlukahlukene. I-valve isetshenziselwa kakhulu "ukuvula" noma "ukuvala" i-valve, kodwa ama-plungers aklanywe ngokukhethekile noma i-clasp ekhethekile nayo ingasetshenziswa ukulungisa i-valve.
