进口不锈钢法兰球阀，白钢球阀性能描述 Performance description 

不锈钢法兰球阀双关双断设计保证阀球完全开启和完全关闭。多种密封结构可选择，保证使用寿命及可靠性。密封结构可选用阀前阀座密封，阀后阀座密封，阀前阀后同时密封。密封有软硬密封可选择，密封表面可硬化处理，适用于多种工况 RETZ The stainless steel flanged ball valve is designed with double closing and double breaking to ensure that the valve ball is fully opened and closed. A variety of sealing structures can be selected to ensure service life and reliability. The sealing structure can be the front valve seat sealing, the rear valve seat sealing, and the front valve and the rear valve can be sealed at the same time. Soft and hard seals can be selected, and the sealing surface can be hardened, which is suitable for various working conditions

可设计阀座由圆柱弹簧或蝶簧预载，具有自动补偿、自密封和阀门中腔自动泄压功能，适用于高温、高压场合 The valve seat can be designed to be preloaded by cylindrical spring or butterfly spring, and has the functions of automatic compensation, self sealing and automatic pressure relief in the valve cavity, which is suitable for high temperature and high pressure occasions

阀球旋转设计能够保证阀球运行平稳，减少操作扭矩 The rotary design of the valve ball can ensure the smooth operation of the valve ball and reduce the operating torque

阀门中腔自动泄压设计，阀门体腔停留介质温度升高而引起异常升压时，不需通过安全阀，而仅靠阀座功能就可自动泄压，提高阀门在输送液体介质时安全性 The design of automatic pressure relief in the middle chamber of the valve. When the temperature of the medium in the valve chamber rises and causes abnormal pressure rise, it is not necessary to pass the safety valve, but only the valve seat function can automatically relieve the pressure, improving the safety of the valve when delivering liquid medium

产品结构设计特点 Product structure design features 

阀杆防吹出结构设计 Valve stem anti-blowing structure design

阀杆防吹出结构设计，下端大上端小的阀杆在上端盖和螺丝的定位下，即使在阀腔异常的情况下，也能保证阀杆不会被介质吹出 retz品牌 Valve stem anti-blowing structure design, the lower end is larger and the upper end is smaller Under the positioning of the upper end cover and screws, even in the valve cavity is abnormal In the case of, it can also ensure that the valve stem will not be blown out by the medium

防静电设计 Anti-static design

固定球阀通过防静电设计使球体、阀杆、阀体形成静电通道。从而将球体与阀座开关过程中由于摩擦产生的静电通过阀体引到大地，防止静电火花可能引起的火灾或爆炸危险The fixed ball valve adopts anti-static design to make the ball, stem and valve The body forms an electrostatic channel. So that the ball and the seat are switched During the process, static electricity generated by friction is led to the ground through the valve body, Prevent the risk of fire or explosion caused by static sparks.

防火结构设计 Fireproof structure design

当发生火灾时，当非金属材料制作的阀座及密封件在高温下损坏后，特别设计的金属对金属辅助密封结构，有限的防止介质大量泄漏 In the event of a fire, when the valve seats and seals made of nonmetallic materials are damaged at high temperatures, the specially designed metal-to-metal auxiliary sealing structure can prevent a large amount of medium leakage
