Two Piece PVC Irrigation Plastic Ball Valve With Stainless Steel Handle

PVC two-piece ball valve with stainless steel handle

Introduction

The working principle of the two-piece ball valve is to make the valve unblocked or blocked by rotating the valve. The ball valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, convenient maintenance, the sealing surface and the spherical surface are often closed, and are not easily eroded by the medium, and are widely used in various industries.

working principle

open process
1. In the closed position, the ball is pressed against the valve seat by the [wiki]mechanical[/wiki] of the valve stem.
2. When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and the angular plane at the bottom makes the ball disengage from the valve seat.
3. The valve stem continues to lift and interacts with the guide pin in the helical groove of the valve stem, so that the ball begins to rotate without friction.
4. 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.

shutdown process
1. When closing, turn the handwheel clockwise, the valve stem starts to descend and the ball leaves the valve seat and starts to rotate.
2. Continue to rotate the handwheel, the valve stem is acted by the guide pin embedded in the upper spiral groove, so that the valve stem and the ball rotate 90° at the same time.
3. When it is about to close, the ball has rotated 90° without contact with the valve seat.
4. During the last few turns of the handwheel, the angular plane at the bottom of the valve stem is mechanically wedged to press the sphere so that it is tightly pressed on the valve seat to achieve complete sealing.
