Choke valve chinhu chikuru chemuti weKisimusi uye chakagadzirirwa kudzora kugadzirwa kwemafuta mutsime, zvinhu zvemuviri uye zvikamu zvechivharo chevhavha zvinonyatsoenderana neAPI 6A uye NACE MR-0175 Standard Specifications, uye inoshandiswa zvakanyanya. yekuchera peturu pamahombekombe nepamhenderekedzo. Iyo throttle valve inonyanya kushandiswa kugadzirisa kuyerera uye kumanikidzwa kwemaitiro akawanda; Kune marudzi maviri ekuyerera ekudzora mavharuvhu: yakagadziriswa uye inogadziriswa. Anogadziriswa throttle mavharuvhu akakamurwa kuita tsono mhando, yemukati cage sleeve mhando, yekunze keji sleeve mhando uye orifice ndiro mhando maererano chimiro; Zvinoenderana nemaitiro ekushanda, inogona kukamurwa kuita bhuku uye hydraulic maviri. Mhedziso yekubatanidza yekuvhara Valve ishinda kana Flange, yakabatana neasina kana flange. Choke valve inowira mukati: yakanaka choke valve, tsono choke valve, inogadziriswa yakachinga vharafu, cage choke valve uye orifice choke valve, nezvimwe.
