Hard seal ball valve classification: a one-way sealing: only in the direction of the valve seal sealing label direction. Bidirectional sealing: can be sealed in two directions
结构形式: 球阀的结构形式分为浮动球式和固定球式,连接形式为法兰连接、焊接连接及螺纹连接。
Structure: structure of ball valve is divided into floating ball and fixed ball type, connection form for the flange connection, welding connection and screw connection.
具有普通球阀的各项性能指标外、还特具备了耐高温、耐摩擦和双流项进、出口 自密封功能,其中二块式还备有了出口单向密封、由不锈钢弹簧来调节阀座,使阀门的扭矩更加均衡,阀门在 高频率、高温差、高压差的条件下,开关性能稳定。
The performance of the ordinary ball outside, also has high temperature resistance, friction resistance and double entry into, exit from the sealing function, of which two block is equipped with the outlet one-way sealing, the stainless steel spring to adjust the seat, the valve torque is more balanced, the valve in the high frequency, high temperature difference, pressure difference under the condition of stable performance, switch.
