Le khasii-rubber ehlelwe i-butterfly valveUhlobo lwe-valve olusebenzisa ipuleti le-batterfly eliyindilinga njengokuvula nokuvala ingxenye futhi ujikeleze ngesiqu se-valve ukuvula, vala futhi ulungise isiteshi se-fluid. Ipuleti levemvane lei-rubber ehlelwe i-butterfly valveifakwe ekuqondisweni kobubanzi bepayipi. Esiteshini se-cylindrical of thei-rubber ehlelwe i-butterfly valveUmzimba, iplanethi enomugqa onomumo we-disc ujikeleza ezungeze i-eksisi, futhi i-angle yokujikeleza iphakathi kuka-0 ° no-90 °. Lapho ijikeleza ku-90 °, i-valve ivuleke ngokuphelele.
Amaphuzu wokwakha nokufaka

2. Kuzo zonke izinhlobo zama-valves wezandla ezifakwe kupayipi lokufakelwa okushisayo, isibambo ngeke sibe phansi.
3. Ukuhlolwa okubukwayo kufanele kwenziwe ngaphambi kokuthi i-valve ifakiwe, futhi igama le-valve kufanele lihlangabezane nezidingo ze-National Standard "General Valve Mark" GB1220. Nge-valve enengcindezi yayo engasebenzi kune-1.0MPA futhi idlala indima ekunciphiseni ipayipi eliyinhloko, amandla nokuhlolwa kokusebenza okuqinile kufanele kwenziwe ngaphambi kokufakwa, futhi kuvunyelwe ukusetshenziselwa ngemuva kokuphumelela isivivinyo. Ngesikhathi sokuhlolwa kwamandla, ingcindezi yokuhlola yisikhathi esingu-1.5 ukucindezelwa okushiwo, kanti isikhathi asikho ngaphansi kwemizuzu engu-5. Izindlu ze-valve kanye nokupakisha kufanele kube ukuqeqeshwa ngaphandle kokuvuza. Ekuhlolweni kokuqina, ingcindezi yokuhlola yisikhathi esingu-1.1 ukucindezelwa okushiwo; Ingcindezi yokuhlola kufanele ihlangabezane nezidingo ze-GB50243 standard ngesikhathi sokuhlolwa, kanye nendawo enophawu lwe-valve disc ifanelekile uma kungekho ukuvuvukala.
Amaphoyinti wokukhetha umkhiqizo
1. Amapharamitha aphezulu okulawula wei-rubber ehlelwe i-butterfly valveukucaciswa nobukhulu.
2. Ingasebenza ngesandla, ngogesi noma nge-zipper, futhi ingalungiswa kunoma iyiphi i-angle ngaphakathi kwebanga le-90 °.
