As a further description of the above technical solution:
the valve rod is connected inside the butt joint column in a sliding mode.
As a further description of the above technical solution:
the valve rod sequentially penetrates through the butt joint column, the valve core inclination ring and the middle sealing gasket and is fixedly connected to the top end of the special-shaped block.
As a further description of the above technical solution:
The special-shaped block is connected inside the valve body in a sliding mode.
As a further description of the above technical solution:
The inclined surface of the flashboard is contacted with the valve cover.
As a further description of the above technical solution:
The valve cover is communicated with the valve body.
The utility model has the following beneficial effects:
according to the utility model, the valve cover is not required to be directly controlled when the gas is started through the cooperation of the components such as the middle sealing gasket, the cotter pin, the valve core inclined ring, the special-shaped block and the like, and the middle sealing gasket is controlled to be double-sided and is safer to use integrally.
