Problems solved by technology
The air-supplementing air pressure water tank can better solve this problem, but few use the air-enhancing air pressure water tank at present, because it is difficult to control the gas-stopping effect when it is disconnected from the electricity.
At present, there is no report on the use of ring-type fire prevention and anti-gas valve devices.

Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] A ring-type fire prevention and anti-air valve device, such as figure 1 , figure 2 , image 3 and Figure 4 As shown, it is a mechanical valve suitable for automatic opening and closing in the fire-fighting air pressure water tank. It prevents the compressed gas from continuing to flow into the fire-fighting pipe network when the liquid in the fire-fighting air pressure water tank is exhausted when it is used for initial fire extinguishing. It does not have the effect of extinguishing the fire, but plays a role of supporting combustion. The device can automatically close the valve body in time when the pressurized water in the fire-fighting air pressure water tank is exhausted, so as to prevent the compressed gas from flowing into the fire-fighting pipe network. Its specific structure is: the valve core lower seat 4 and the bottom of the valve ou...

A ring type anti-air valve device, the valve core seat and the bottom of the valve outer body are equipped with a valve base flange, the valve outer body is provided with a valve water inlet, the rubber ring is embedded in the valve seat, and the valve water inlet There is a guide rail between the outer body of the upper valve and the upper seat of the valve core. There is a floating ball connecting plate inside the ring type floating ball. There is a floating ball connecting plate fixing hole at the center of the floating ball connecting plate. There is a transmission connecting rod fixing hole, the bottom of the transmission connecting rod passes through the transmission connecting rod fixing hole and is fixed on the valve core upper seat, and the top of the transmission connecting rod passes through the floating ball connecting plate fixing hole and is movably connected with the floating ball connecting plate by bolts. This device overcomes the siphon effect caused by too fast water flow and large internal and external pressure difference, and can smoothly discharge fire-fighting water, and at the same time eliminates the harmful effect of compressed gas entering the fire-fighting pipe network. It is suitable for fire-fighting pressurized water tanks with high flow rate and large flow rate to prevent compressed gas from entering the fire-fighting pipe network, which will not only fail to extinguish the fire, but also cause combustion-supporting phenomena.
Description
technical field [0001] The invention relates to an air-stop valve, in particular to a ring-type fire-fighting and air-stop valve device for an air-supplementing fire-fighting air pressure water supply device. Background technique [0002] At present, bladder-type air-pressure water tanks are used in fire-fighting air-pressure water tanks, but the service life of the bladder-type air-pressure water tanks is short, the maintenance cost is high, and the valve cannot realize automatic switching. When the fire is extinguished at the initial stage, if the valve cannot be automatically opened and closed, when the liquid in the fire pressure water tank is exhausted, the compressed gas will continue to flow into the fire pipe network. Air-supplementing air pressure water tanks can better solve this problem, but at present, few use air-enhancing air pressure water tanks, because it is difficult to control the gas-stopping effect without electricity. The invention provides a ring-type...
