The surface of described valve body hard sealing gasket and spool hard sealing gasket is loop configuration, and the width of annular surface is the 3-5 millimeter.
When combining closely, spool hard sealing gasket and valve body hard sealing gasket be the closed condition of left and right passage.Move upward under the drive of spool at cylinder, spool hard sealing gasket is the opening state of left and right passage when leaving valve body hard sealing gasket.
The utility model has the advantages that:
1) owing to two hard sealing gaskets of employing closely contact, and the area of contact of sealing gasket is few, and is wear-resistant so sealability is better, long service life.
2) the craspedodrome synchronized movement of valve rod and cylinder, quick action, and adjustable-speed.
3) because the valve rod of moving element has seal ring and stuffing box packing protection, exempt the pollution of the rough gas that contains tar and water, guaranteed that start is flexible, therefore be specially adapted to contain the rough gas pipeline of big water gaging and tar.
