Power Station Steam Ball Valve (One-piece)
Features
1. 1/4 rotation greatly reduces the wear and friction of packing to prevent leakage.
2. The anti scour ball structure ensures that the opening area is larger at the same opening degree at the initial stage of the adjustment, reduces the differential pressure faster, reduces the scouring time of the differential pressure, and effectively extends the service life.
3. The graphite packing and seat adjustment alarm are pre-tightened by the butterfly spring to avoid locking under high temperature.
4. Under some special working conditions (such as the drain valve of the main steam pipe, which is also responsible for the discharge of steam from the startup heat pipe in addition to the drainage), due to the high flow rate and large impact force, the ball in the ceramic cavity will produce high-frequency reciprocating vibration to impact the valve rod. The torque increases sharply, which is easy to cause the adjusting rod to break and twist, which makes it unable to be used normally. The throttling orifice is used for decentralized adjustment the energy when the valve is opened at the beginning to minimize the erosion and cavitation.
5. More exquisite with integrated design.
