Mumamiriro ezvinhu akajairika, mavharuvhu eindasitiri haaite bvunzo dzesimba paanenge achishandiswa, asi mushure mekugadzirisa muviri wevhavha uye chivharo chevhavha kana kukuvadzwa kwekuora kwemuviri wevhavha uye chivharo chevhavha chinofanira kuita miedzo yesimba.Kune mavharuvhu ekuchengetedza, iyo yekumisikidza kudzvanywa uye kudzoserwa kumanikidzwa uye mamwe maedzo anozoenderana nezvakatemwa uye zvinoenderana nemitemo.Ivhavha inofanira kuongororwa simba uye kusimba isati yaiswa.Mavharuvhu epakati nepakati anofanira kuongororwa .Valve pressure test inowanzo shandiswa midhiya imvura, oiri, mhepo, chiutsi, nitrogen, etc. Mhando dzese dzemaindasitiri mavharuvhu anosanganisira pneumatic mavharuvhu kumanikidza bvunzo nzira dzinotevera:

1.Ball valvepressure test method

Muedzo wesimba wepneumatic ball valve unofanirwa kuitwa mubhora hafu yakavhurika nyika.

(1)Bhora rinoyangararavalve tightness test: valve iri hafu yakazaruka, imwe mugumo inounzwa mukati meyedzo yepakati, uye imwe magumo yakavharwa;Shandura bhora kakawanda, vhura magumo akavharwa kana vharuvhu yakavharwa, uye tarisa kuvharika kwekuita kwekurongedza uye gasket, uye hapafanirwe kuve nekudonha.Wobva wasuma svikiro rebvunzo kubva kune rumwe rutivi uye dzokorora bvunzo iri pamusoro.

(2)Fixed ball valve tightness test: pamberi pekuedzwa, bhora rinoshandurwa kakawanda pasina mutoro, uye iyo yakagadziriswa bhora valve iri munzvimbo yakavharwa, uye chiyero chekuedza chinotorwa kubva kune imwe mugumo kusvika kune yakakosha;Iyo yekumanikidza geji inoshandiswa kutarisa kusevha kwekuita kweiyo inlet end.Iko kurongeka kweiyo geji yekumanikidza ndeye 0.5 ~ 1, uye iyo yekuyera chiyero ndeye 1.5 nguva yekumanikidza kwekuyedza.Munguva yakatarwa, hapana depressurization phenomenon inokodzera;Wobva wasuma svikiro rebvunzo kubva kune rumwe rutivi uye dzokorora bvunzo iri pamusoro.Zvadaro, vharuvhu iri hafu yakazaruka, migumo yose yakavharwa, mukati memukati muzere ne media, uye iyo yekurongedza uye gasket inotariswa pasi pekumanikidza kwekuyedza pasina kubuda.

(3)Iyo nzira nhatu dzebhora vharafu sinofanira kuongororwa kusimba munzvimbo dzakasiyana-siyana.

2.Tarisa vharafupressure test method

Chengetedza valve test state: simudza rudzi cheki cheki dhisiki axis iri munzvimbo yakatwasuka uye yakatwasuka;Iyo axis ye swing cheki yevhavha chiteshi uye axis ye disc inenge yakaenzana nemutsara wakatwasuka.

Munguva yekuyedzwa kwesimba, svikiro rekuyedza rinounzwa kune yakatsanangurwa kukosha kubva kumagumo ekupinza, imwe magumo yakavharwa, uye muviri wevharuvhu nevhavhavhavha yevhavha inokodzera pasina kubuda.

Muedzo wekuisa chisimbiso uchaunza bvunzo yepakati kubva kumagumo ekubuda, tarisa nzvimbo yekuisa chisimbiso kumagumo ekupinza, uye kurongedza uye gasket zvichave zvinokodzera kana pasina kuvuza.
