| description | The utility model relates to a waterproof hammer air inlet and outlet valve which comprises a valve body, an air outlet barrel is arranged at the top of the valve body, an air outlet hole is formed in the side wall of the air outlet barrel, an air outlet plate is fixedly arranged above the inner wall of the valve body, vent holes are symmetrically formed in the air outlet plate, the top end of a hollow pipe penetrates through the air outlet plate, and a flow dividing valve element is fixedly arranged on the outer wall of the hollow pipe. When a pipeline starts to be filled with liquid (such as water), when the water filling speed of the pipeline is too high, the gas flow speed is increased, the flow dividing valve element ascends, high-speed gas can be decelerated through the flow guiding plates, the speed is prevented from being too high, and the flow dividing valve element is prevented from being damaged. When the vent hole is plugged by the plugging block, the gas displacement in unit time is reduced, and |
