The application discloses multi-functional domestic pipeline gas is shut off valve regularly. Referring to fig. 1, the gas valve comprises a gas valve body 20, a timing cut-off device 30, a timer 40, a multifunctional protection device 50, a first sealing diaphragm 60, a second sealing pressure plate 70, a timing dial 80 and a timing hand wheel 90. The valve body 20 comprises an air inlet passage 1, an air outlet passage 2, a first air inlet 3, a second air inlet 4, a first air outlet 5, a second air outlet 6, a first inner cavity 7, a second inner cavity 8, a third inner cavity 9, a first guide hole 10 and a third guide hole 11. The timing cutting device 30 is installed in the first inner cavity 7 of the valve body. The cutting device 30 comprises a first transmission shaft 21, a spring 22, a sealing washer 23, an O-ring 24 and a first sealing plate 25. The sealing plate 25 is designed with a second guide hole 251 and a vent hole 252.

Referring to fig. 1, a sealing plate 25 is installed at the upper end of the valve body first air outlet hole 5, and a compacted O-ring 24 is fixed by a first screw 253. The lower end of the first transmission shaft 21 is placed in the first guide hole 10 of the valve body 100, passes through the spring 22, the sealing washer 23 and the second guide hole 251 upwards, and contacts with the first sealing diaphragm 60. The first sealing diaphragm 60 is mounted intermediate the first and second

internal chambers

7, 8 of the valve body. The second sealing plate 70 comprises a sealing plate 61, a pressure plate 62 and a second screw 63, wherein the second sealing plate 70 is arranged on the first sealing diaphragm 60, and the first sealing diaphragm 60 is fixedly compacted through the second screw 63 to realize the sealing of the first inner cavity 7. The pressure plate 62 is mounted on the second sealing plate 61.

Referring to fig. 1, the timer 30 includes a timer center shaft 31, a timer cover plate 32, a timer ejector rod 33, and a third screw 34. The timer is mounted in the second interior chamber 8 of the valve body 100 and the cover plate 32 of the timer 40 is secured to the valve body 100 by the third screw 34. The timing dial is installed at the upper end of the valve body 100, the timing hand wheel is installed on the timing dial 80, and is fixedly connected with the center shaft 31 of the timer 40. The multifunctional protector 50 comprises a transmission shaft 41, a second sealing membrane 42, a nut 43, a valve cover 44, a magnet plate 45, a magnet 46, a third fixing screw 47 and a handle 48. The second sealing membrane is placed in the third inner cavity 9 of the valve body 100, the second sealing membrane 42 and the second transmission shaft 41 are compacted and sealed by screwing the nut 43, and the second sealing membrane 42 is compacted through the valve cover 44, so that the third inner cavity 9 is sealed.

Referring to fig. 1, a magnet plate 45 is installed at the middle of the valve cover 44, and a magnet 46 is placed on the magnet plate 45. The lower end of the transmission shaft 41 is placed in the third guide hole 11 of the valve body 100, passes through the nut 43, the second sealing membrane 42, the magnet plate 45 and the magnet 46, and the upper end is connected with the handle 48. The handle 48 is fixed to the top end of the second transmission shaft 41 by a third screw 42. The timing hand wheel 90 is rotated clockwise to start the timer 40, so that the ejector rod 33 of the timer 40 pushes the pressure plate 62 forwards to generate pressure downwards, the first sealing membrane 60 is driven to move downwards, the first transmission shaft 21 is driven to move downwards, the sealing gasket 23 for sealing the vent hole 252 is driven to move downwards, the gas leaves the first sealing plate 25, and the gas input from the gas inlet passage 1 passes through the first gas inlet 3, passes through the first gas outlet 5, is output from the vent hole 252 and enters the first inner cavity 7 of the valve body. The handle 48 is pulled upwards to drive the transmission shaft 21, the magnet 46 arranged on the transmission shaft 21 and the second sealing diaphragm 42 to move upwards, so that the gas entering the first inner cavity 7 is output from the second air outlet 6 through the second air inlet 4 and enters the third inner cavity 9, the gas entering the inner cavity 9 forms stable air pressure, the second sealing diaphragm does not move downwards any more, and the multifunctional protection device is in an open state.

Referring to fig. 2, if gas leakage occurs in the direction of the gas outlet passage 2, the gas pressure in the third inner cavity 9 is reduced, the gas pressure is reduced, the transmission shaft 41 moves downward, the magnet 46 is attracted downward by the magnet plate 45, and the pressure generated by the magnet downward presses the second sealing membrane 42 against the second gas outlet hole 6, so that the function of automatically cutting off the gas leakage is realized. If accidental air cut-off occurs, because no air flow is input, the air pressure of the third inner cavity 9 can suddenly decrease, when the pressure of the third inner cavity 9 is smaller than the suction force of the suction plate 45, the magnet 46 is sucked downwards by the suction plate 45, the pressure generated downwards by the magnet drives the second transmission shaft 41 to move downwards, so that the second sealing diaphragm compresses and seals the second air outlet 6, and when air is supplied again, because the multifunctional protection device is in a closed state, even if the kitchen range is still in an open state, gas leakage cannot occur, thereby realizing the protection function of accidental air cut-off. If the air pressure of the air supply cannot meet the air consumption requirement, the air pressure of the third inner cavity 9 can be reduced when the under-pressure occurs, and the multifunctional protection device can be triggered to be automatically closed, so that the under-pressure protection function is realized.

Referring to fig. 2, when the multifunctional domestic pipeline gas timing cut-off valve is used, when the set time is up, the ejector rod 33 of the timer 40 is reset, the downward pressure of the pressure plate 63 is relieved, the upward supporting force of the spring 22 is restored, the first transmission shaft 21 is moved upward, the sealing washer 23 arranged on the transmission shaft is driven to abut against the vent hole 252, and the timing cut-off function is realized. After the timing cut-off device 30 is automatically closed, since no air source is input into the third inner cavity 9 of the valve body 20, the third inner cavity 9 has no air pressure, the multifunctional protection device 50 can automatically fall back to close the second air outlet 6, and when the gas is used, the multifunctional protection device can also be automatically closed at the same time after the timing cut-off device is automatically closed.

The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
