Ball valve and gate valve are the same type of valve, the difference is that its closing member is a sphere, and the sphere rotates around the center line of the valve body to achieve opening and closing. The three-way ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Three-way ball valve is a new type of valve that is widely used. The high platform ball valve can be divided into straight-through type, three-way type and right-angle type according to its channel position. The latter two ball valves are used to distribute the medium and change the flow direction of the medium.
(1) The three-way ball valve has a long service life, large flow capacity and small resistance.
(2) The pneumatic 3 way ball valve and the three-way ball valve adopt an integrated structure in structure, the sealing type of the 4-face valve seat, less flange connections, high reliability, and lightweight design.
(3) The three-way ball valve is divided into two types: single-acting and double-acting according to the action type. The single-acting type is characterized in that once the power source fails, the ball valve will be in the state required by the control system.
(1) The pneumatic 3 way ball valve is easy to maintain, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
(2) When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
(3) It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
(4) The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length.
(5) Simple structure, small size and light weight.
(6) It is tight and reliable, with good sealing performance, and has been widely used in vacuum systems.
(7) The three-way ball valve is easy to operate, opens and closes quickly, and only needs to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
(1) The ball valve with transmission mechanism should be installed upright.
(2) Leave the position where the valve handle rotates.
(3) Can not be used as throttling.
The working principle of the three-way ball valve is to make the valve unblocked or blocked by rotating the valve core. The ball valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often in a closed state, not easy to be eroded by media, and are widely used in various industries. The three-way ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The three-way ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as no friction on the switch, the seal is not easy to wear, and the opening and closing torque is small. This reduces the size of the fitted actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict shut-off of the medium. It is widely used in petroleum, chemical industry, urban water supply and drainage and other working conditions that require strict cut-off.
