Isimiso sokusebenza kanye nezindawo zokwakha kanye nokufakwa kwe-rubber ehlezi uvemvane valve

Ii-rubber ehlezi uvemvane valveiwuhlobo lwevalvu esebenzisa ipuleti levemvane eliyindilinga njengengxenye yokuvula neyokuvala futhi izungeza nesiqu se-valve ukuze ivule, ivale futhi ilungise uketshezi olumanzi. Ipuleti butterfly of thei-rubber ehlezi uvemvane valveifakwe ohlangothini lobubanzi bepayipi. Ku-cylindrical channel ye-i-rubber ehlezi uvemvane valveumzimba, ipuleti uvemvane okumise okwediski lizungeza i-eksisi, futhi i-engeli yokuzungeza iphakathi kuka-0° no-90°. Uma ijikeleza ku-90 °, i-valve ivuleke ngokugcwele.

Amaphuzu wokwakha nokufaka

1. Indawo yokufaka, ubude, kanye nesiqondiso sokungenisa nokuthekelisa kufanele kuhlangabezane nezidingo zedizayini, futhi ukuxhumana kufanele kuqine futhi kuqine.

2. Kuzo zonke izinhlobo zamavalvu enziwa ngesandla afakwe epayipini lokufakwa kwe-thermal, isibambo akufanele sibe phansi.

3. Ukuhlolwa okubonakalayo kufanele kwenziwe ngaphambi kokuba i-valve ifakwe, futhi i-nameplate ye-valve kufanele ihlangabezane nezidingo zezinga lamanje likazwelonke elithi "General Valve Mark" GB12220. Ukuze i-valve ingcindezi yayo yokusebenza ingaphezu kuka-1.0MPa futhi idlala indima ekunqamuleni ipayipi elikhulu, amandla nokuhlolwa kokusebenza okuqinile kufanele kwenziwe ngaphambi kokufakwa, futhi kuvunyelwe ukusetshenziswa ngemva kokuphumelela ukuhlolwa. Ngesikhathi sokuhlolwa kwamandla, ingcindezi yokuhlola iphindwe izikhathi ezingu-1.5 ingcindezi encane, futhi ubude besikhathi abukho ngaphansi kwemizuzu emi-5. Izindlu ze-valve kanye nokupakishwa kufanele zifaneleke ngaphandle kokuvuza. Ekuhlolweni kokuqina, ingcindezi yokuhlola iphindwe izikhathi ezingu-1.1 ingcindezi yokulinganisa; ingcindezi yokuhlola kufanele ihlangabezane nezidingo zezinga le-GB50243 ngesikhathi sokuhlolwa, futhi indawo yokuvala i-valve disc ifanelekile uma kungekho ukuvuza.

Amaphuzu okukhetha umkhiqizo

1. Imingcele yokulawula eyinhloko ye-i-rubber ehlezi uvemvane valvekukhona ukucaciswa nobukhulu.

2. Ingasetshenziswa ngesandla, ngogesi noma ngoziphu, futhi ingalungiswa kunoma iyiphi i-engeli ngaphakathi kwebanga elingu-90°.

3. Ngenxa ye-shaft eyodwa kanye ne-valve plate eyodwa, umthamo wokuthwala ulinganiselwe, futhi impilo yesevisi ye-valve ifushane ngaphansi kwezimo zomehluko omkhulu wengcindezi kanye nesilinganiso esikhulu sokugeleza.
