Three way water ball valve

Q644F-16CThree way water ball valveThe principle of performance

A、 Opening process

In the closed position, the ball is tightly 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 causes the ball to detach from the valve seat.

The valve stem continues to lift and interacts with the guide pin in the spiral groove of the valve stem, causing the ball to start rotating frictionlessly.

Until it reaches the fully open position, the valve stem is lifted to the limit position, and the ball rotates to the fully open position.

B、 Closing process

When closing, rotate the handwheel clockwise and the valve stem begins to descend, causing the ball to move away from the valve seat and begin to rotate.

Continuing to rotate the handwheel, the valve stem is subjected to the action of the guide pin embedded in its spiral groove, causing both the valve stem and the ball to rotate 90 ° simultaneously.

When it was about to close, the sphere had already rotated 90 degrees without contact with the valve seat.

After a few turns of the handwheel, the angular plane at the bottom of the valve stem mechanically wedges and presses the ball tightly against the valve seat, achieving * sealing.

1. Leave a position for the valve handle to rotate.

2. Cannot be used for throttling.

Ball valves with transmission mechanisms should be installed upright.

The working principle of a three-way ball valve is to rotate the valve to make it open or close. Ball valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by media. They are widely used in various industries.

Three way ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of media.

Three way ball valve is a relatively new type of ball valve, which has some unique structural characteristics such as frictionless opening and closing, low sealing wear, and small opening and closing torque. This can reduce the specifications of the accompanying actuator. Equipped with a multi turn electric actuator, it can achieve adjustment and tight cutting of the medium. Widely applicable to working conditions such as petroleum, chemical, urban water supply and drainage that require strict cut-off.
