Abstract
The utility model discloses a gas check water seal valve, which comprises a sealed container, wherein an air inlet and an air outlet are arranged at the top of the sealed container, and a flushing valve is arranged at the upper part of one side of the sealed container; a non-impact water filling device is arranged at the upper part of the other side of the sealed container, and a water drain valve is arranged at the lower part of the sealed container; a lens through which the water level can be observed is arranged in the sealed container, and a water seal water tank with an upper opening is arranged below the air inlet in the sealed container; and an adjusting device is arranged below the water seal water tank and is connected with the flushing valve through a connecting hose. The gas check water seal valve is characterized in that: a U-shaped pipe is connected onto the non-impact water filling device, and one end of the U-shaped pipe is connected with the non-impact water filling device; and a port of the other end of the U-shaped pipe is in a conical shape, and the height of the port of the other end of the U-shaped pipe is lower than that of the non-impact water filling device. The gas check water seal valve has the advantages that: the sealing effect is reliable, the degree of automation is high, the cost is low, and the gas check water seal valve can replace a complicated gas check water seal valve.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of adjustable coal gas check water-sealing valve.
Background technique
Traditional coal gas check water-sealing valve adopts water-stop mostly.Adopt easy to operate, the good sealing effect of water-stop.But coal gas is easy to go out from the priming valve internal leakage when adding water, causes environmental hazard.Therefore need provide a kind of new technological scheme to address the above problem.
The model utility content
The purpose of this utility model provides a kind of coal gas check water-sealing valve of good sealing effect.
The technical solution adopted in the utility model is:
A kind of coal gas check water-sealing valve, comprise seal container, described seal container top is provided with suction port and air outlet, described seal container one upper lateral part is provided with flush valve, opposite side top is provided with does not have the priming apparatus of impact, the bottom is provided with Draw off valve, described sealed container interior is provided with the lens of observable water level height, the suction port below is provided with unlimited seal water tank suitable for reading in the described seal container, be provided with adjustable apparatus below the described seal water tank, described adjustable apparatus is connected with flush valve by connecting flexible pipe, described nothing is impacted on the priming apparatus and is connected with one " U " type pipe, an end that is somebody's turn to do " U " type pipe impacts priming apparatus with nothing and is connected, and the port of the other end is coniform and highly is lower than does not have the height that impacts priming apparatus.
The utility model has the advantages that: sealing effect is reliable, automaticity is high, cost is low, alternative baroque coal gas check water-sealing valve.
