Cholinga chogwiritsa ntchito valavu yoyezera ndikuletsa kuti cholumikiziracho chisabwerere m'mbuyo. Nthawi zambiri, valavu yoyezera iyenera kuyikidwa pamalo otulukira pampu. Kuphatikiza apo,valavu yowunikira iyeneranso kuyikidwa pamalo otulukira compressorMwachidule, kuti tipewe kubwerera kwa cholumikiziracho, valavu yowunikira iyenera kuyikidwa pa chipangizocho, chipangizocho kapena paipi. Nthawi zambiri, valavu yowunikira yoyimirira imagwiritsidwa ntchito paipi yopingasa yokhala ndi mainchesi 50. Mavalavu owunikira olunjika amatha kuyikidwa pa mapaipi onse opingasa komanso olunjika. Vavu yapansi nthawi zambiri imayikidwa paipi yopingasa yokha pamalo olowera pa pampu, ndipo cholumikiziracho chimayenda kuchokera pansi kupita pamwamba. Vavu yowunikira yozungulira imatha kupangidwa kukhala ndi kuthamanga kwakukulu kogwira ntchito, PN imatha kufika 42MPa, ndipo DN ikhozanso kukhala yayikulu kwambiri, mpaka 2000mm kapena kuposerapo. Kutengera ndi zinthu zomwe zili mu chipolopolocho ndi chisindikizo, ingagwiritsidwe ntchito pa cholumikizira chilichonse chogwirira ntchito komanso kutentha kulikonse kogwirira ntchito. Cholumikiziracho ndi madzi, nthunzi, gasi, cholumikizira chowononga, mafuta, chakudya, mankhwala, ndi zina zotero. Kutentha kwapakati kogwirira ntchito kuli pakati pa -196 ~ 800℃. Malo oyika valavu yowunikira yozungulira siwoletsedwa. Nthawi zambiri imayikidwa paipi yopingasa, koma imathanso kuyikidwa paipi yopingasa kapena paipi yopendekera.

Zochitika zoyenera zavalavu yoyezera gulugufendi amphamvu komanso amphamvu, ndipo nthawi zoyikira zimakhala zochepa. Chifukwa mphamvu yogwira ntchito ya valavu yowunikira gulugufe singakhale yokwera kwambiri, koma m'mimba mwake mwa nomineyumu ikhoza kukhala yayikulu kwambiri, yomwe imatha kufika pa 2000mm, koma mphamvu yowunikira ndi yochepera 6.4MPa. Vavu yowunikira gulugufe imatha kupangidwa kukhala mtundu wa clamp, womwe nthawi zambiri umayikidwa pakati pa ma flange awiri a payipi, pogwiritsa ntchito mawonekedwe olumikizira clamp. Malo oyika valavu yowunikira gulugufe si oletsedwa. Itha kuyikidwa pa payipi yopingasa, kapena pa payipi yoyima kapena payipi yopendekera.
Valavu yoyezera diaphragm ndi yoyenera mapaipi omwe amatha kugwidwa ndi nyundo yamadzi. Diaphragm imatha kuchotsa nyundo yamadzi yomwe imayamba chifukwa cha kubwerera kwa sing'anga. Chifukwa kutentha kogwira ntchito ndi kupanikizika kwa valavu yoyezera diaphragm zimachepetsedwa ndi zinthu za diaphragm, nthawi zambiri imagwiritsidwa ntchito m'mapaipi okhala ndi mphamvu yochepa komanso kutentha kwabwinobwino, makamaka oyenera mapaipi amadzi apampopi. Kutentha kwapakati kogwira ntchito kuli pakati pa -20~120℃, ndipo kuthamanga kogwira ntchito ndi <1.6MPa, koma valavu yoyezera diaphragm imatha kupangidwa ndi mainchesi akulu, ndipo DN yayikulu imatha kufika pa 2000mm. Mavavu oyezera diaphragm ali ndi kukana bwino kwa nyundo yamadzi, kapangidwe kosavuta komanso mtengo wotsika wopanga, kotero akhala akugwiritsidwa ntchito kwambiri m'zaka zaposachedwa.
Kuyambira chizindikiro chaValavu yoyezera mpira ndi chozungulira chophimbidwa ndi rabala, ili ndi magwiridwe antchito abwino otsekera, ntchito yodalirika komanso kukana bwino kugwiritsa ntchito nyundo yamadzi; ndipo popeza chisindikizocho chingakhale mpira umodzi kapena mipira ingapo, chingapangidwe kukhala chokulirapo chachikulu. Komabe, chisindikizo chake ndi chozungulira chopanda kanthu chophimbidwa ndi rabara, chomwe sichiyenera mapaipi amphamvu kwambiri, koma mapaipi apakati ndi otsika mphamvu. Popeza zinthu zomangira za valavu yoyezera mpira zitha kupangidwa ndi chitsulo chosapanga dzimbiri, ndipo chozungulira chopanda kanthu cha chisindikizocho chikhoza kuphimbidwa ndi pulasitiki ya polytetrafluoroethylene engineering, chingagwiritsidwenso ntchito m'mapaipi okhala ndi zinthu zowononga. Kutentha kwa mtundu uwu wa valavu yoyezera ndi pakati pa -101~150℃, kuthamanga kwapadera ndi ≤4.0MPa, ndipo kukula kwapadera ndi pakati pa 200~1200mm.
