Flanged (Fixed) Mpira Valve
Muhtasari wa Bidhaa
Aina ya Q47 ya valve ya mpira ya kudumu ikilinganishwa na valve ya kuelea ya mpira, inafanya kazi, shinikizo la maji mbele ya nyanja ya yote hupitishwa kwa nguvu ya kuzaa, haitafanya tufe kwa kiti ili kusonga, hivyo kiti hakitabeba pia. shinikizo nyingi, hivyo fasta mpira valve moment ni ndogo, kiti cha deformation ndogo, imara kuziba utendaji, maisha ya huduma ya muda mrefu, husika na shinikizo la juu, kipenyo kikubwa. Advanced spring kabla ya mkutano wa kiti na sifa binafsi inaimarisha kufikia muhuri mto. .Kila valve ina viti viwili na inaweza kufungwa katika kila mwelekeo, hivyo ufungaji hauna vikwazo vya mtiririko.Je, ni kizazi kipya cha valve ya juu ya utendaji, valve ya mpira wa flange inafaa kwa mabomba ya muda mrefu na mabomba ya jumla ya viwanda, nguvu zake, usalama. , upinzani wa mazingira magumu katika kubuni ya kuzingatia maalum, yanafaa kwa aina mbalimbali za vyombo vya habari vya babuzi na visivyo na babuzi.
Kanuni ya kufanya kazi ya valves za mpira zisizobadilika:
Mpira wa valve ya mpira wa kudumu umewekwa na kuungwa mkono na shafts mbili zilizowekwa zilizounganishwa na mpira. Wakati imefungwa, chini ya hatua ya shinikizo la kati, mpira hautatoa uhamisho, kwa kawaida huunganishwa na mpira kwenye shimoni la juu, la chini. shimoni ina fani zinazoviringika, au fani za kuteleza. Ili kupunguza msuguano wa jarida wakati wa kufungua na kufunga. Punguza torque ya uendeshaji. Vali hii ya mpira isiyobadilika inafaa kwa vali za mpira zenye kipenyo kikubwa. Shina mbili za valve zimewekwa. Wakati wa kufanya kazi, shinikizo la maji halitafanya mpira kwenye harakati za kiti cha valve, kiti cha valve hakitakuwa na shinikizo nyingi na deformation. Sehemu ya shina ya valve ina fani za kulainisha binafsi ili kupunguza msuguano, na torque ya kubadili ni ndogo. Viti vyote viwili vya vali hupakiwa mapema na chemchemi. Muhuri hupitisha PTFE iliyochongozwa ndani ya kishikilia chuma, na chemchemi hutolewa nyuma ya pete ya chuma ili kuhakikisha kuwa kiti cha vali kiko karibu na mpira. Shinikizo kwenye chumba cha vali inapoongezeka. kwa njia isiyo ya kawaida na kuzidi nguvu ya chemchemi, kiti cha valve hutolewa kutoka kwa mpira ili kufikia athari ya misaada ya shinikizo la moja kwa moja, na kiti cha valve kinawekwa upya kiotomatiki baada ya shinikizo. -kuokoa na maisha marefu ya huduma. Inafaa sana kwa bomba la umbali mrefu na bomba la jumla.
