Abstract

The invention discloses a water hammer air valve and a water hammer gas discharging method during pipeline use. The water hammer air valve comprises a valve body, a bonnet and a protective cover, wherein the bonnet is provided with an opening, the protective cover is disposed on the opening, the valve body is provided with a valve opening for being communicated with a pipeline, a high-speed gas feeding and discharging device which is used for discharging gases stayed in the pipeline during water filling to the outside and shutting down the valve after pipeline water filling is completed is disposed in the inner cavity of the valve body, the output end of the high-speed gas feeding and discharging device is communicated with the outside through the opening of the bonnet, and the valve opening of the valve body is communicated with a bottom gas discharging throttling device for limiting the gas displacement of the pipeline to the inner cavity of the valve body; a trace gas discharging device for discharging mixed, residual and / or precipitated gases in the pipeline to the outside through the opening of the bonnet after the high-speed gas feeding and discharging device shuts down the valve is further disposed in the high-speed gas feeding and discharging device. By the water hammer air valve, water hammer reduction and pipeline safety protection are achieved, blowing blocking during high-speed gas discharging is avoided, and valve closing water hammer is eliminated.

Description

technical field [0001] The invention relates to the field of water pipeline valves, in particular to a bottom-mounted throttling and exhaust type anti-hammer air valve. In addition, the invention also relates to a waterproof hammer exhaust method during pipeline use. Background technique [0002] In long-distance water pipelines, the accumulated gas in the pipeline will reduce the efficiency of pipeline water filling and even make it difficult to complete it smoothly. Therefore, high-speed intake and exhaust valves (air valves) need to be used to remove the gas in the pipeline when filling the pipeline. At the same time, due to the single structure and function of the existing high-speed exhaust valve (air valve), another micro-exhaust valve needs to be installed on the pipeline to discharge the air precipitated in the water when the pipeline is full; Suction valve (or vacuum breaker valve), when the pipeline stops the pump, vents, or explodes, it can avoid problems such as...
