Product Description

Product Description

It is suitable for liquid and gas medium pipeline and equipment, used to cut off and connect the medium in the pipeline. Has a good seal, easy to operate, the sealing surface is not easy to damage, long service life, not easy to produce water hammer phenomenon and so on. Clockwise rotation of the handwheel for the closure, and vice versa for the open, without the aid of any lever

Features

Cast iron stop valve, including the valve body and valve cover installed in the valve body, the valve body is equipped with inlet and outlet cavities, inlet and outlet cavities are set at the connection of the valve seat, the valve seat is set under the sealing cushion layer, the valve body and the valve cover is equipped with a sealing gasket between the valve body and the valve cover, the valve body and the valve cover through the bolts fixed connection, the valve cover is installed in the valve cover inserted into the stem, the valve stem is installed at the upper end of the handwheel, hand wheel and fixed connection with the valve stem through the bolts. The valve stem is equipped with a stem nut, a packing pressure plate, a packing pressure sleeve, a packing layer and an upper sealing ring in order from the bottom to the top, and the lower end of the valve stem is equipped with a valve disk, which is fixedly connected to the valve stem through screws, and the lower end of the valve disk is installed with a sealing ring, and an elastic sealing layer is provided on the lower surface of the valve disk

Detailed Photos

  1 In the closed position, the valve body is tightly pressed on the valve seat by the mechanical pressure exerted by the valve stem.
2 When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and the angular plane at its bottom causes the ball to disengage from the seat.
3The stem continues to lift and interacts with the guide pins in the stem's spiral groove, causing the ball to begin to rotate frictionlessly.
4 Until it reaches the fully open position, the stem lifts to the limit position and the ball rotates to the fully open position.
Closing process
1When closing, rotate the handwheel clockwise, the valve stem begins to descend and causes the ball to leave the seat and begin to rotate.
2 Continue to rotate the handwheel, the valve stem is embedded in the role of the guide pin in the spiral groove, so that the valve stem and gate at the same time rotate 90 °.
3 When the valve is about to close, the gate has rotated 90° without contact with the seat.
4 The last few revolutions of the handwheel rotation, the angular plane at the bottom of the valve stem mechanically wedge to compress the ball, so that it is tightly pressed against the valve seat to achieve a complete seal.
