產(chǎn)品結(jié)構(gòu)特點 Construction features
1、操作省力:介質(zhì)壓力在球體上產(chǎn)生作用力全部傳遞給上下軸承,球體不會相對位置移動,兩端閥座密封受力均勻,操作力矩低。
2、采用彈簧預(yù)加載荷的可動金屬閥座結(jié)構(gòu),能適用高溫、高壓以及各種介質(zhì)管路。
3、根據(jù)客戶要求,可以設(shè)計能適用于含顆粒、料漿等介質(zhì)。
4、廣泛適用于食品、醫(yī)藥、石油、化工、天然氣、鋼鐵、環(huán)保、造紙等介質(zhì)管路。
1. Operation saving force: the force of the medium pressure on the sphere is transmitted to the upper and lower bearings, the ball will not move relative position, the seating seal on both ends is uniform and the operating moment is low.
2. The movable metal seat structure with spring preloading can be used for high temperature, high pressure and various medium pipes.
3. According to customer requirements, it can be designed to be suitable for particles, slurry and other media.
4. It is widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, paper, etc.
