产品结构特点 Construction features 1、操作省力:介质压力在球体上产生作用力全部传递给上下轴承,球体不会相对位置移动,两端阀座密封受力均匀,操作力矩低。 适用介质:水、气、油品、天然气和酸碱腐蚀性介质 技术规范 Technical specification 试验压力 Test prssure
2、采用弹簧预加载荷的可动金属阀座结构,能适用高温、高压以及各种介质管路。
3、根据客户要求,可以设计能适用于含颗粒、料浆等介质。
4、广泛适用于食品、医药、石油、化工、天然气、钢铁、环保、造纸等介质管路。
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.
