I-valve yebhola ye-PVCiyivalvu eyenziwe ngezinto ze-PVC, esetshenziselwa kabanzi ukusika noma ukuxhuma imidiya kumapayipi, kanye nokulawula nokulawula uketshezi. Lolu hlobo lwe-valve lusetshenziswe ezimbonini eziningi ngenxa yokumelana nokugqwala okungasindi futhi okuqinile. Okulandelayo kuzonikeza isingeniso esiningiliziwe sesakhiwo esiyisisekelo kanye nezici zama-valve ebhola lepulasitiki le-PVC.
1. Umzimba we-valve
Umzimba we-valve ungenye yezingxenye eziyinhloko zeAma-valve ebhola e-PVC, okwenza uhlaka oluyisisekelo lwe-valve yonke. Umzimba we-valve we-valve yebhola ye-PVC uvame ukwenziwa ngempahla ye-PVC, enokumelana nokugqwala okuhle futhi engakwazi ukuzivumelanisa nokwelashwa kwemithombo yezindaba eyonakalisayo. Ngokwezindlela ezihlukene zokuxhuma, ama-valve ebhola e-PVC angahlukaniswa abe izinhlobo ezihlukahlukene ezifana nokuxhumeka kwe-flange nokuxhumana okufakwe imicu.
2. Ibhola le-valve
Ibhola le-valve litholakala ngaphakathi komzimba we-valve futhi liyingxenye eyindilinga, futhi eyenziwe ngezinto ze-PVC. Lawula ukuvulwa kanye nokuvala medium ngokuzungezisa ibhola valve. Lapho imbobo ebholeni levalvu ihambisana nepayipi, okuphakathi kungadlula; Lapho ibhola le-valve lijikeleza endaweni evaliwe, indawo yayo izovimba ngokuphelele indlela yokugeleza okuphakathi, ngaleyo ndlela ifinyelele umphumela wokuvala.
3. Isihlalo se-valve
Isihlalo se-valve siyisici esiyinhloko esithintana nebhola le-valve futhi sinikeze umphumela wokuvala. Kumavalvu ebhola e-PVC, isihlalo se-valve ngokuvamile senziwe ngezinto ze-PVC futhi siklanywe ngesakhiwo se-groove esiyindilinga esihambisana nebhola le-valve. Lokhu kungakha ukusebenza okuhle kokuvala lapho ibhola le-valve linamathele ngokuqinile esihlalweni se-valve, kuvimbele ukuvuza okuphakathi.
4. Indandatho yokuvala
Ukuze kuthuthukiswe ukusebenza kokuvala, ama-valve ebhola epulasitiki e-PVC nawo afakwe izindandatho zokuvala. Lezi zindandatho zokuvala ngokuvamile zenziwe ngezinto ezifana ne-EPDM noma i-PTFE, engagcini nje ngokuqinisekisa ukusebenza kahle kokuvala, kodwa futhi ingakwazi ukumelana noshintsho lokushisa ngaphakathi kwebanga elithile.
5. Isikhungo Esiphethe
OkagesiAma-valve ebhola e-PVC, ngaphezu kwezingxenye eziyisisekelo ezishiwo ngenhla, kukhona futhi ingxenye ebalulekile - i-actuator kagesi. Ama-actuator kagesi afaka izingxenye ezifana namamotho, amasethi egiya, namavalvu e-solenoid, anesibopho sokushayela ibhola le-valve ukuze lijikeleze futhi lilawule isimo sokugeleza kwendawo ephakathi nendawo. Ngaphezu kwalokho, ama-actuator kagesi angakwazi futhi ukusekela ukulawula okuzenzakalelayo okukude, okwenza ukusebenza kwalo lonke uhlelo kube lula futhi kusebenze kahle.
6. Indlela yokuxhuma
Ama-valve ebhola e-PVCukusekela izindlela eziningi zokuxhuma, kufaka phakathi kodwa kungagcini ekuxhumekeni kwentambo yangaphakathi, ukuxhumana kwentambo yangaphandle, ukuxhuma kwe-butt welding, uxhumano lwe-socket welding, nokuxhumeka kwe-flange. Ukukhethwa kwendlela yokuxhumana efanele kuncike esimweni sohlelo lokusebenza kanye nezidingo zobuchwepheshe.
