Pressure test nzira yebhora vharafu

Kuedzwa kwesimba kwepneumatic ball valve kunofanira kuitwa pasi pemamiriro ebhora hafu yakazaruka. ① Chisimbiso bvunzo yeinoyangarara bhora vharafu: isa vharafu muhafu yakavhurika nyika, pinza yekuyedza yepakati kune imwe magumo uye wovhara imwe magumo; tenderedza bhora kakawanda, vhura magumo akavharwa kana vharafu iri munzvimbo yakavharwa kuti iongororwe, uye tarisa kuvharika kwekuita kwekurongedza uye gasket panguva imwe chete, pasina kubuda. Wobva wasuma svikiro rebvunzo kubva kune rumwe rutivi uye dzokorora bvunzo iri pamusoro. ② Chisimbiso bvunzo yeyakagadziriswa bhora vharafu: pamberi pekuyedzwa, tenderera bhora kakawanda pasina mutoro, uye yakagadziriswa bhora valve iri munzvimbo yakavharwa. Sumai test medium kubva kune imwe mugumo kusvika kune yakatarwa kukosha; tarisa kuvharwa kwechisimbiso chekutungamirira-mumagumo nekugadzirisa gauge. Iko kurongeka kweiyo pressure gauge ndeye 0.5-1, uye huwandu hwacho ndeye 1.5 nguva dzekumanikidza kwekuyedza. Kana pasina kumanikidzwa kudonha chiitiko mukati menguva yakatarwa, inokodzera; ipapo svikiro rebvunzo rinounzwa kubva kune rumwe rutivi, uye bvunzo iri pamusoro inodzokororwa. Zvadaro, vharuvhu iri mu semi yakazaruka mamiriro, migumo miviri yakavharwa, uye mukati memukati muzere nepakati. Pasi pekumanikidzwa kwekuyedza, tarisa kurongedza uye gasket, uye hapazove nekudonha. ③ Nzira nhatu dzebhora mavharuvhu anoyedzerwa kusimba panzvimbo dzese.
