When the medium flows leftwards from the right side, the medium passes through the pressure plate flow channel, passes through the valve plate and the sealing ring, enters the valve, and when the valve needs to be closed, the valve rod is driven to rotate by the adjusting valve body support, the valve plate is driven to rotate by the rotation of the valve rod, the valve plate is rotated by 90 degrees, and the sealing ring is extruded by the valve plate. The sealing ring generates certain deformation and displacement, and the sealing ring is simultaneously leaned against the left side in the valve body seal under the action of a medium, so that the sealing effect is achieved.
Preferably, the valve body support is provided with a packing pressing plate in a sliding manner, the packing pressing plate is fixed on the valve body through a bolt, and the bottom of the packing pressing plate is filled with sealing packing
By adopting the technical scheme, the valve body is filled with the sealing filler, the sealing of the valve rod and the valve plate is ensured, and the sealing filler is extruded and protected by the filler pressing plate.
Preferably, a sealing gasket is fixed at the joint of the bottom plug and the valve body.
By adopting the technical scheme, the sealing washer plays a role in sealing and waterproofing.
Preferably, the top of the valve body is provided with a groove, and the packing pressing plate is arranged in the groove.
By adopting the technical scheme, the valve bracket is convenient to mount, the neck of the valve is specially sunken, and the packing pressing plate is mounted in the concave pit, so that the valve bracket is attractive and practical.
Preferably, the pressing plate is provided with a plurality of threaded holes.
By adopting the technical scheme, the pipe fitting is connected with the valve body through the threaded hole.
