我们的固定球阀具有以下特点:1.       弹簧加载阀座密封结构:因介质本身的压力不能确保阀座可靠密封,而预紧力长期使用后又会衰减时,特别设计的弹簧加载阀座密封结构,能确保阀门长期可靠使用.2.       辅助密封结构:根据用户的需要,球阀的阀座及阀杆的密封部位可加装注脂阀.当密封部位因擦伤而引起泄露时,通过注脂阀注入密封脂,可起瞬时密封作用.3.       阀杆防吹出结构及有效密封结构:阀杆采用下装式,设置带有密封垫片的倒密封结构,倒密封的密封力随阀腔压力的增高而增大,从而确保阀杆的密封效果.当阀腔异常升压时,阀杆不会被冲出.填料采用设计合理的V型结构,能将阀腔内部的介质压力及外部压盖的锁紧力有效的转化成阀杆的密封力.4.       防火结构:根据用户的需要,球阀可设计成防火结构.当万一发生火灾而使密封圈烧损时,球阀的各个密封部位均能形成金属的硬密封结构,有效阻止介质的扩散,防止火灾的扩大.5.       防静电结构:球体与阀杆、阀杆与阀体之间设置导电弹簧,使阀门在开启过程中产生的静电能通过所设置的静电通道传入地下,达到清除静电的目的.避免静电打火点燃易燃介质,确保系统安全.6.       自动泄压结构:当滞留于阀腔内的液体介质因温度升高而产生气化使中腔压力异常升高时,中腔介质能依靠本身的推力推动阀座向后靠而自动泄压,确保阀体安全.7.       防止误操作结构:在阀的全开或全关位置设有锁定孔,需要时可加锁,起到安全保险作用.  另外,固定球阀可根据压力大小选择不同的密封形式:进口端密封;出口端密封;进、出口端双向密封.批发说明了解批发详情请联系卖家Ball Valve Specifications:Feature Type: 1PC / 2PC / 3PC, Investment casting, fire safe design, reduce bore / full boreFloating Type/ Trunning Mounted* Design: BS5351, MSSSP72, API6D* Size Range: 2"-36"* Pressure Rating: ANSI 150LB-1500LB / PN16-PN100* End Connection:  RF / RTJ / BW* Trim: Soft seal / Metal seal* Testing: BS 6755(Part-I)Also known as flow valves, which are quarter-turn and straight through apparatus. Ball valves have round closure element that contains a matching pair of rounded seats that allow necessary sealing to take place. The ball valves are used in various industries like chemical, oil, textile, petrochemical and pharmaceutical industries. Cast iron, cast steel, cast stainless steel, alloy steel and many other metals are used while manufacturing the ball valves. The ball valves manufactured and supplied by Balsara Engineering are easy to use and can maintain high pressure, high flow of temperature and high volume. The various types of ball valves manufactured and supplied by us are 1PC ball valves, 2PC ball valves and 3PC ball valves etc.
