The model utility content
Technical problem to be solved in the utility model provides a kind of combustion gas hemisphere water-sealing valve device with the safe high-level water tank, can in water system abnormal fault, when stopping to supply water, supply water to the hemisphere water-sealing valve timely.Can effectively prevent from affecting the poorly sealed problem of hemisphere water-sealing valve and occur, ensure safety in production.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of combustion gas hemisphere water-sealing valve device with the safe high-level water tank is provided, comprise gas main, the hemisphere water-sealing valve, inlet valve, high-order buffer tank and automatic regulating valve, described gas main is communicated with the two ends, the left and right sides of hemisphere water-sealing valve, and hemisphere water-sealing valve upper end is equipped with relief valve; Hemisphere water-sealing valve lower end water pipe is connected with respectively three road devices, one tunnel series connection drain valve, one tunnel connect successively inlet valve and flowmeter also have one tunnel connect successively check valve, automatic stop valve, ball valve and high-order buffer tank, and high-order buffer tank position is higher than the hemisphere water-sealing valve; High-order buffer tank also is communicated with automatic regulating valve.
Described hemisphere water-sealing valve upper end is equipped with relief valve by relief sewer.
Connect with drain valve by the half ball valve waste pipe in described hemisphere water-sealing valve lower end.
Described inlet valve links to each other by the half ball valve water pipe with flowmeter.
Described flowmeter is electrically connected with automatic stop valve by control system.
Beneficial effect
The utility model can the hemisphere water-sealing valve breaks down when cutting off the water at normal water supply, supplies water toward the hemisphere water-sealing valve timely.Can effectively prevent hemisphere water-sealing valve lack of water, thereby avoid the not tight problem of valve seal to occur, ensure safety in production.
