Japan CKD pneumatic ball valve 2? 3-way ball valve can be divided into: single gate type, double gate type and elastic gate type; parallel gate type gate valve can be divided into single gate type and double gate type. According to the thread position of the valve stem, it can be divided into two types: open gate valve and dark gate valve. When the gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the shutter is pressed against the valve seat of the other side only by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most of the gate valves are forced to seal, that is, when the valve is closed, the external force is forced to press the gate to the valve seat to ensure the sealing of the sealing surface. The gate of the gate valve moves linearly with the valve stem, which is called the lift gate valve (also called the open gate valve). Usually there is a trapezoidal thread on the lifting rod, and the rotary motion is changed into a linear motion by the nut at the top end of the valve and the guide groove on the valve body, that is, the operating torque is changed to the operating thrust.

When the valve is opened, when the lifting height of the shutter is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely unblocked, but this position cannot be monitored during operation. In actual use, the apex of the valve stem is used as a mark, that is, the position where the valve is opened, as its fully open position. Performance requirements of Japan CKD pneumatic ball valve 2? 3-way ball valve

1. Commutation performance: Under the specified working conditions, can the solenoid valve be reliably reversible after being energized, and can be reliably reset after power failure.

2. Internal leakage: The internal leakage of the electronically controlled reversing valve refers to the leakage from the high pressure chamber to the low pressure chamber under different working conditions under the specified working conditions.

3. Commutation and reset time: The time required from the energization of the electronically controlled iron to the termination of the spool reversal. The reset time is the time from the electromagnetic power-off to the return of the spool to the initial position.

4. Pressure loss: The pressure loss of the electronically controlled directional control valve is composed of the flow loss and the throttling loss generated when the liquid flow flows through the valve port of the electronically controlled directional control valve.

5. Commutation frequency: the maximum number of commutations allowed per unit time. 6. Service life: The solenoid valve is used until the main components are damaged, normal commutation and resetting actions cannot be performed, or the main performance indicators are obviously deteriorated. Exceeded the number of commutations experienced by the specified indicators.

Japan CKD pneumatic ball valve 2? 3-way ball seat adjustment ring is used to change the size of the passage between the valve flap and the adjustment ring, thereby changing the amount of pressure accumulated in the chamber between the valve flap and the adjustment ring when the valve is initially opened. When the valve seat adjustment ring is raised, the degree of pressure buildup is increased, so that the phase of the valve proportional opening is reduced and the sudden rapid opening is achieved relatively quickly. Therefore, raising the seat adjustment ring can reduce the discharge pressure. It should be noted that the seat adjustment ring must not rise too close to the valve flap. In this way, the leakage at the sealing surface may cause the valve to suddenly open prematurely, but since the medium pressure is not enough to keep the valve flap in the open position, the valve flap is closed again, and the valve jumps.
