整体焊接球阀
DISC (THERMO-DYNAMIC) TRAP
 
结构:
1.阀体采用碳钢或不锈钢无缝管压制成形。
2.球体材质可采用不锈钢304、316制作。研磨精细不锈钢球体,具有优良的抗腐蚀性能和密封性能。
3.采用浮球结构,斜面弹性密封圈紧压在球体之上,即使在压力不稳定的情况下,阀门可以保证严密。
4.本阀门可以提供对焊、法兰、承插焊、内缧纹等连接形成。开闭采用手柄、蜗轮传动、电动等传动方式。
 
Structure:
1.The valve body is made from carbon steel or seamless stainless steel pipe by pressed forming;
2.The valve body material can be stainless steel 304 and 316. The finely grind stainless steel ball has excellent performance in anti-corrosion and tightness.
3.The float-ball structure is applied with the beveled elastic sealing ring tightly pressed against the ball body so that the valve is kept tight even if the pressure is unstable.
4.The valve can be connected by butt-welding, flanged connection, socket welding and inner threaded connection. It can be opened/closed by a handle, turbine drive, and motorized drive.
 
特点:
1.SZQ球阀在工作过程中,密封面能够自补偿作用,它能延长球阀使用寿命。
2.SZQ自密封式球阀关键零件。它是由高强度极限,耐高温。耐腐蚀、耐磨损、无毒,经受长期高压高温而不丧失弹性且能保持稳定尺寸的复合材料所制造。
3.密封圈是高科技耐磨产品,经受几十万次往复运动的测试,仍可提供良好的密封性能,才能保证阀门的使用寿命。
4.阀门密封圈可以在摄氏-10℃-250℃的条件下,连续使用而不会失效。
5.产品阀体、阀杆可根据各种长度加长、易于保温、便于安装。
6.SZQ阀门特点无泄漏,开闭快、结构新颖,用途广泛,是工程项目首选的新品种。
 
Features:
1.When the SZQ ball valve is at work, its sealing face can play a role in self-compensation, extending the service life of the ball valve;
2.Key parts of the SZQ self-sealed ball vale are of high strength, resistant to high temperature. It is made from composite materials, resistant to corrosion and abrasion, nontoxic, without losing elasticity, and keeping stable dimensions under long-time high pressure and high temperature.
3.The sealing ring is a kind of high-tech resistant-to-abrasion product, capable of maintaining good sealing performance after undergone testing by reciprocal movements of hundreds of thousands times, ensuring service life of the valve.
4.The valve sealing ring can be used continuously without any effect under the temperature of -10℃~ -250℃.
5.The valve body and stem can be extended, easy for heat preservation and installation;
6.Features of SZQ valve: no leakage, quick opening/closing, novel structure, wide uses, a preferred new product in projects.
