Brief description of the drawings
Fig. 1 is the structure diagram of gas shutoff valve of the present invention.
Embodiment
Below in conjunction with attached drawing and specific embodiment, the present invention is further elaborated.
Such as the gas shutoff valve structure diagram that Fig. 1 is the present invention, including valve body 1 and valve deck 2,2 one end connection valve of valve deck
Body 1, the other end are connected with unidirectional valve assembly 3；Water storage cavity 4 is equipped with the valve deck 2,4 bottom of water storage cavity is equipped with diaphragm 7,
7 marginal end of diaphragm is removably fixed on the valve body 1, and the diaphragm 7 is used to separate combustion gas.
Preferably, 2 side of valve deck is equipped with the exhausting-gas hole 6 being connected with 4 side wall of water storage cavity, is additionally provided with water storage cavity 4
One floating ball 5 for being used to seal the exhausting-gas hole 6；When current enter water storage cavity 4, the air in water storage cavity is squeezed and passes through
The exhausting-gas hole 6 is discharged, and as water increases in water storage cavity 6, floating ball 5 starts to float, seal the exhausting-gas hole 6.
Preferably, it is to be bolted to be threadedly coupled between the check valve 3 and valve deck 2, between valve deck 2 and valve body 1.
Preferably, the gas shutoff valve further includes control unit, control unit include automatic controller, sensor and
The solenoid valve being connected on feed pipe；Described solenoid valve one end connects feed pipe, and the other end passes through water pipe and the check valve
Water pipe head end 8 is connected, and solenoid valve is connected with sensor with automatic controller.
Preferably, the sensor includes temperature sensor and/or the sensor for sensing gas leakage；The temperature
Sensor is arranged at the source of fire hazardous in kitchen furred ceiling or kitchen, and event occurs for sensing fire in time；It is described
The sensor of detection gas leakage is arranged at gas pipeline nearby or near fuel cartridge, can be by detecting gas component in air
Concentration or directly sense gas component so that in real time monitoring judge whether combustion gas leaks in kitchen.
Preferably, the sensor on automatic controller with being equipped with wireless communication module, sensor and automatic controller
Between wireless connection realized by the communication module, i.e. sensor automatically controls the signal detected by being wirelessly transmitted to
On device.
Preferably, 5 material of floating ball is plastics or rubber, is conducive to floating ball and floats.
Preferably, the exhausting-gas hole 6 and 5 contact jaw of floating ball be bell mouth shape, be conducive to floating ball energy it is more stable seal institute
State exhausting-gas hole.
The operation principle and process of gas shutoff valve of the present invention：When needing to block combustion gas, opening connects with the check valve
Head end 8 is connected the valve set on feed pipe, and current are entered in the water storage cavity 4 in valve deck 2 by check valve 3, at this time, unidirectionally
Air in valve 3, water storage cavity 4 and water supply line is discharged after being extruded by current by exhausting-gas hole 6.With entrance water storage cavity 4
Water increases, and the floating ball 5 in the water storage cavity 4 starts to float, and floating ball 5 is adsorbed at exhausting-gas hole under the guiding of current,
And exhausting-gas hole 6 is blocked, as water is expired in water storage cavity 4, simultaneously as the effect of check valve 3, current are not returned in feed pipe,
So that the hydraulic pressure that the diaphragm 7 touched with 4 bottom connection of water storage cavity is subject to gradually increases, diaphragm 7 starts to push, and seals combustion
Gas import, cuts off combustion gas.When needing to be again switched on combustion gas, the valve on feed pipe is closed, while can pass through row by one
The small tool of stomata 6 opens up floating ball 5, and the water in water storage cavity 4 is flowed out by exhausting-gas hole 6, and the pressure that diaphragm 7 is subject to gradually subtracts
Small, diaphragm 7 resets, and fuel gas inlet is opened, and recovers ventilation.
