Pressure Safety Valve Inspection, Maintenance and Fault Elimination

1. Safety valve is an important safety accessory for special pressure equipment. Safety valve inspection is essential, as well The safety valve is an automatic valve, which does not rely on any external force but uses the force of the medium itself to discharge a rated amount of fluid to prevent the pressure from exceeding […]

Precautions to the Use of Safety Valves

The function of safety valves is to prevent the pressure of the medium in the pipeline or device from exceeding the specified value, so as to achieve the purpose of safety protection. The safety valve is a safety protection valve. Its opening and closing parts are normally closed under the action of external force. When […]

3PC Ball Valves Working Principle

The working principle of the three-piece ball valve is as follows: 1. Opening process  In the closed position, the ball is pressed against the valve seat by the mechanical pressure of the valve stem. When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and its bottom angular plane makes the […]

Ball Valve Installation and Maintenance

There are manual ball valves, pneumatic ball valves, electric ball valves   1. Installation of ball valve Preparation before installation: The pipelines before and after the ball valve are ready. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to […]

Ball Valves Application Fields

Since the ball valve usually uses rubber, nylon and polytetrafluoroethylene as the seat sealing ring material, its use temperature is limited by the seat sealing ring material. The cut-off function of the ball valve is achieved by pressing the metal ball against the plastic seat under the action of the medium (floating ball valve). Under […]

Ball Valves Structure, Characteristics, Advantages & Classification

The ball valve is evolved from the plug valve, which has the same lifting action of 90 degrees. The ball valve can be closed tightly with only a 90-degree rotation and a small torque. The completely equal internal cavity of the valve provides a straight flow channel with little resistance for the medium. The main […]
