Cholinga chogwiritsa ntchito valavu yowunika ndikuletsa kubwereranso kwapakati. Nthawi zambiri, valavu yoyendera iyenera kukhazikitsidwa potuluka pampu. Kuphatikiza apo,valavu yowunikira iyeneranso kuikidwa pamtundu wa compressor. Mwachidule, pofuna kupewa kubwereranso kwa sing'anga, valve yowunikira iyenera kuikidwa pazida, chipangizo kapena payipi.Kawirikawiri, valavu yowunikira yowunikira imagwiritsidwa ntchito paipi yopingasa yokhala ndi 50mm mwadzina. Mavavu owongolera molunjika amatha kuyikidwa pamapaipi opingasa komanso oyima. Valavu yapansi nthawi zambiri imayikidwa papaipi yoyima polowera polowera, ndipo sing'angayo imayenda kuchokera pansi kupita pamwamba. Chovala choyang'ana cha swing chingapangidwe kukhala chovuta kwambiri chogwira ntchito, PN ikhoza kufika ku 42MPa, ndipo DN ingakhalenso yaikulu kwambiri, mpaka 2000mm kapena kuposa. Kutengera ndi zinthu za chipolopolo ndi chisindikizo, chingagwiritsidwe ntchito pa sing'anga iliyonse yogwira ntchito komanso kutentha kulikonse. Sing'anga ndi madzi, nthunzi, gasi, sing'anga zikuwononga, mafuta, chakudya, mankhwala, etc. sing'anga kutentha osiyanasiyana ntchito ndi pakati -196 ~ 800 ℃. Kuyika kwa valavu ya swing check valve sikuletsedwa. Nthawi zambiri imayikidwa paipi yopingasa, koma imathanso kuyikidwa papaipi yoyima kapena paipi yopendekera.

Nthawi zovomerezeka zavalavu ya butterflyndi otsika kuthamanga ndi lalikulu m'mimba mwake, ndipo nthawi unsembe ndi ochepa. Chifukwa kuthamanga kwa ntchito ya valve yoyang'ana gulugufe sikungakhale kwakukulu, koma m'mimba mwake mwadzina ukhoza kukhala waukulu kwambiri, womwe ukhoza kufika kuposa 2000mm, koma kuthamanga kwadzina kuli pansi pa 6.4MPa. Valovu yoyang'ana gulugufe imatha kupangidwa kukhala mtundu wochepetsera, womwe nthawi zambiri umayikidwa pakati pa mbali ziwiri za payipi, pogwiritsa ntchito mawonekedwe olumikizira agulugufe. Malo oyika agulugufe samaletsa. Ikhoza kuikidwa pa payipi yopingasa, kapena paipi yoyima kapena paipi yolowera.
Vavu yoyang'anira diaphragm ndiyoyenera mapaipi omwe amakonda nyundo yamadzi. The diaphragm imatha kuthetsa nyundo yamadzi chifukwa cha kubwereranso kwa sing'anga. Chifukwa kutentha kogwira ntchito ndi kupanikizika kwa ma valve ogwiritsira ntchito diaphragm kumachepetsedwa ndi zida za diaphragm, nthawi zambiri zimagwiritsidwa ntchito pamapaipi otsika komanso otsika, makamaka oyenera mapaipi amadzi apampopi. Kutentha kwapakati pa ntchito kuli pakati pa -20 ~ 120 ℃, ndipo kuthamanga kwa ntchito ndi <1.6MPa, koma valavu yoyang'ana diaphragm ikhoza kupangidwa ndi mainchesi akuluakulu, ndipo DN yapamwamba imatha kufika kupitirira 2000mm. kukana nyundo, kapangidwe kosavuta komanso mtengo wotsika wopanga, kotero akhala akugwiritsidwa ntchito kwambiri m'zaka zaposachedwa.
Popeza chisindikizo chavalavu yoyang'ana mpira ndi gawo lopangidwa ndi mphira, ili ndi ntchito yabwino yosindikiza, ntchito yodalirika komanso kukana nyundo yabwino yamadzi; ndipo popeza chisindikizocho chikhoza kukhala mpira umodzi kapena mipira yambiri, ikhoza kupangidwa kukhala lalikulu lalikulu. Komabe, chisindikizo chake ndi dzenje lozungulira yokutidwa ndi mphira, amene si oyenera mapaipi mkulu-anzanu, koma mapaipi sing'anga ndi otsika-anzanu. dzenje dzenje la chisindikizo chitha yokutidwa ndi polytetrafluoroethylene engineering mapulasitiki, itha kugwiritsidwanso ntchito mapaipi ndi ambiri zikuwononga TV. Kutentha kwa ntchito ya mtundu uwu wa valve cheke kuli pakati pa -101 ~ 150 ℃, kuthamanga mwadzina ndi ≤4.0MPa, ndipo m'mimba mwake mwadzina ndi pakati pa 200 ~ 1200mm.
