Abstract
The utility model relates to a gas pressure water tank overpressure self-relieving device for top gas pressure emergency fire water-supply devices. A check valve is connected in series with a gas inlet pipe; a gas outlet pipe is by-passed on the gas inlet pipe at the rear end of the check valve; a ball valve 5 is installed at the tail end of the air outlet pipe; and an outlet of the ball valve is connected in parallel with a ball valve and a solenoid valve. The gas pressure water tank overpressure self-relieving device has the advantages of realizing manual and automatic gas exhausting, guaranteeing a make-up water pump to normally supplement water for the gas pressure water tank, and preventing water inside the gas pressure water tank from flowing backward into a top gas pressure device and a pressure stabilizing air compressor.
Description
Technical field
The utility model relates to the emergent fire water supply equipment air pressure tank superpressure automatic decompression device of a kind of gas roof pressure.
Background technology
The emergent fire water supply equipment of existing gas roof pressure such as Fig. 1, auto-pneumatic cylinder 11 directly is communicated with by air inlet pipe 12 with jack unit 16, this structure is often in commissioning test, following problem usually takes place: 1, the water in the auto-pneumatic cylinder 11 pours in down a chimney into jack unit 16 by air inlet pipe 12, and enter the pressure-reducing valve group through jack unit 16, cause the corrosion of jack unit and the obstruction of pressure-reducing valve group; 2, when voltage stabilizing air compressor machine 15 operation, because the water level in the air pressure tank 11 is higher, the water in the auto-pneumatic cylinder 11 also can pour in down a chimney in the cylinder of voltage stabilizing air compressor machine 15 into, causes the damage to air compressor machine 15; 3, hypertonia often occurring for auto-pneumatic cylinder 11 moisturizing processes, normally moisturizing and do not reach the liquid level upper limit of small pump, thus cause pump motor to transship.
Summary of the invention:
The purpose of this utility model is to solve emergent existing the problems referred to above of fire water supply equipment of gas roof pressure in the prior art, and a kind of gas roof pressure fire water supply equipment air pressure tank superpressure automatic decompression device of meeting an urgent need is provided.The utility model designs the emergent fire water supply equipment air pressure tank superpressure automatic decompression device of a kind of gas roof pressure, comprise auto-pneumatic cylinder, air inlet pipe, stop valve, check-valves, voltage stabilizing air compressor machine, jack unit, it is characterized in that: be connected in series a check-valves in air inlet pipe, the other blast pipe that connects on the air inlet pipe of check-valves rear end, at the terminal mounting ball valve 5 of blast pipe, the ball valve outlet also connects a ball valve and a magnetic valve.The utility model has the advantages that and can realize manually and automatic vent, guaranteed the normal moisturizing of small pump to auto-pneumatic cylinder, the water in the auto-pneumatic cylinder can not pour in down a chimney in the jack unit and voltage stabilizing air compressor machine.
Description of drawings:
Fig. 1 is the prior art constructions schematic diagram,
Fig. 2 is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and construction embodiment the utility model is made detailed operation instruction.
The specific embodiment:
Comprise auto-pneumatic cylinder 1, air inlet pipe 2, stop valve 8, check-valves 3, voltage stabilizing air compressor machine 10, jack unit 6 among the figure, it is characterized in that: at air inlet pipe 2 serial connections one check-valves 3, the other blast pipe 4 that connects on the air inlet pipe 2 of check-valves 3 rear ends, at blast pipe 4 terminal mounting ball valves 5, ball valve 5 outlets also connect a ball valve 6 and a magnetic valve 7.
One check-valves 3 is set on air inlet pipe 2, prevents that the water in the auto-pneumatic cylinder 1 from pouring in down a chimney in the jack unit 6 and voltage stabilizing air compressor machine 10 by air inlet pipe 2; On blast pipe 2, down draw a blast pipe 4, at blast pipe 4 ends (height of handled easily) mounting ball valve 5, and again and access valve 6 and magnetic valve 7.Ball valve 5 is used for debugging, maintenance magnetic valve 7, and ball valve 6 is used for manual exhaust and simulation fire-fighting signal when debugging.With the pressure sensor control magnetic valve 7 that is contained on the equipment pipe network, when the pressure in the auto-pneumatic cylinder 1 was higher than setup pressure value, magnetic valve 7 was opened, and carried out pressure release, and when pressure dropped to setting value, magnetic valve 7 cut out.
