DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] Reference Figure 1-Figure 5 As shown, a multifunctional volumetric gas water heater comprises a shell 1, a water heater body 2 is fixedly installed in the shell 1, a pressure relief pipe 3 communicating with the interior is fixedly connected to the upper end of the water heater body 2, and one end of the pressure relief pipe 3 passes through the shell 1; a sealing ring 4 is fixedly installed in the pressure relief pipe 3, a first spring rod 5 is fixedly installed in the pressure relief pipe 3 through a mounting rod, a sealing plate 6 is fixedly installed at the lower end of the first spring rod 5, and the sealing plate 6 contacts the sealing ring 4. Under the action of the elastic force of the first spring rod 5, the lower surface of the sealing plate 6 contacts the upper surface of the sealing ring 4, thereby blocking the pressure relief pipe 3. Pressure relief pipe 3, as the temperature and air pressure in the water furnace increase, the vertical upward pressure on the sealing plate 6 will also increase, and the elastic force of the first spring rod 5 is greater than the pressure on the sealing plate 6, so that the sealing plate 6 will not separate from the sealing ring 4; a mounting hole is provided on the water furnace body 2, and a pressure pipe 7 is fixedly installed in the mounting hole, and a push block 8 is vertically and slidably installed in the pressure pipe 7 through an elastic component, and a push rod 9 is vertically fixedly installed on the lower surface of the push block 8, and an L-shaped push rod 10 is fixedly installed at the lower end of the push rod 9, and one end of the push rod 10 is located just below the sealing plate 6 On the other hand, a locking assembly for locking the sealing plate 6 is provided on the pressure relief pipe 3, and the elastic assembly includes a fixing frame 11 fixedly installed at the lower end of the pressure pipe 7 and a telescopic spring 12 sleeved on the push rod 9, and the two ends of the telescopic spring 12 are respectively fixedly connected to the push block 8 and the fixing frame 11, and a moving hole is opened on the fixing frame 11, and the push rod 9 is slidably inserted in the moving hole; and as the pressure in the water boiler increases, the push block 8 will be subjected to a vertical upward thrust, and this thrust is greater than the elastic force of the telescopic spring 12, thereby driving the push block 8 to move vertically upward, and the push block 8 moves vertically upward. When the water boiler is in motion, the push rod 9 will drive the push rod 10 to move vertically upward until one end of the push rod 10 contacts the lower surface of the sealing plate 6. The push rod 10 exerts a vertical upward force on the sealing plate 6. Under the combined force of the force exerted by the push rod 10 and the pressure in the water boiler, it is greater than the elastic force of the first spring rod 5. At this time, the sealing plate 6 will be driven to separate from the sealing ring 4, thereby opening the pressure relief pipe 3. At this time, the gas in the water boiler will be discharged from the pressure relief pipe 3 for pressure relief treatment, thereby preventing the gas pressure in the water boiler from being too high and posing a risk of explosion, thereby effectively improving the safety of the device.

[0018] A rectangular hole is provided on the side of the pressure relief pipe 3, and the locking assembly includes a trapezoidal limit block 13 slidably inserted in the rectangular hole and two second spring rods 14 symmetrically fixedly mounted on the trapezoidal limit block 13, one end of the second spring rod 14 is fixedly mounted on the pressure relief pipe 3, and the inclined end of the trapezoidal limit block 13 is located above the sealing plate 6. A transmission assembly for driving the trapezoidal limit block 13 to move is provided on the pressure relief pipe 3, and the transmission assembly includes an inclined plate 15 obliquely fixedly mounted on the upper surface of the trapezoidal limit block 13, a vertical rod 16 vertically fixedly mounted on the upper surface of the push block 8, and an L-shaped rod 17 fixedly mounted on the upper end of the vertical rod 16, one end of the L-shaped rod 17 is slidably connected to the inclined surface of the inclined plate 15; when the sealing plate 6 moves vertically upward to open the pressure relief pipe 3, the sealing plate 6 will contact the inclined surface end of the trapezoidal limit block 13, and under the action of the inclined surface, the trapezoidal limit block 13 will be driven to move horizontally, and the second spring rod 14 will stretch until the sealing plate 6 moves to the upper side of the trapezoidal limit block 13 When the pressure in the water boiler is restored to normal, one end of the L-shaped rod 17 contacts with the inclined surface of the inclined plate 15, and the trapezoidal limit block 13 is separated from the sealing plate 6. At this time, under the action of the elastic force of the first spring rod 5, the sealing plate 6 contacts with the sealing ring 4, thereby blocking the pressure relief pipe 3. Only when the pressure in the water boiler returns to normal, the pressure relief pipe 3 will be closed.

[0019] The elastic coefficient of the telescopic spring 12 is greater than the elastic coefficient of the second spring rod 14, ensuring that when the pressure of the water boiler returns to normal, under the action of the elastic force of the telescopic spring 12, the L-shaped rod 17 can drive the trapezoidal limit block 13 to move through the inclined plate 15.

[0020] A sealing gasket is fixedly installed on the lower surface of the sealing plate 6 , and the sealing gasket is in contact with the sealing ring 4 . When the sealing plate 6 is in contact with the sealing ring 4 , the sealing gasket can ensure the sealing between the two to prevent gas from overflowing from the pressure relief pipe 3 .

[0021] As the pressure in the water boiler increases, the push block 8 will be subjected to a vertical upward thrust, and then the push rod 9 will drive the push rod 10 to move vertically upward until one end of the push rod 10 contacts the lower surface of the sealing plate 6. The push rod 10 exerts a vertical upward force on the sealing plate 6, which will drive the sealing plate 6 to separate from the sealing ring 4, thereby opening the pressure relief pipe 3. At this time, the gas in the water boiler will be discharged from the pressure relief pipe 3 for pressure relief, thereby preventing the gas pressure in the water boiler from being too high and posing a risk of explosion, thereby effectively improving the safety of the device.
