进口平衡式全焊接球阀，全焊接球型平衡阀性能描述 Performance description

平衡式全焊接球阀(全焊接球型平衡阀)阀体采用碳钢或不锈钢无缝钢管/钢板压制成形的全焊结构，球体有浮动式和固定式两种结构；阀座结构采用活塞效应和磨损补偿的设计，密封结构设计为单道和双道软密封圈和金属密封面与球体形成多级密封，保证该系列球阀安全可靠长期稳定的运行 RETZ  The balanced all welded ball valve (all welded ball type balance valve) body is made of carbon steel or stainless steel seamless steel pipe/steel plate pressed into a fully welded structure, and the ball has floating and fixed structures; The valve seat structure adopts the design of piston effect and wear compensation. The sealing structure is designed to form a multi-stage seal between single and double soft sealing rings, metal sealing surface and ball, ensuring the safe, reliable, long-term and stable operation of this series of ball valves
