[0026] It also includes an air inlet pipe 3, an air inlet threaded pipe 4, an air outlet pipe 5 and an air outlet threaded pipe 6; the mounting portion 1 is connected to the outer shell 2, the side of the outer shell 2 is connected to the air inlet pipe 3, the side of the air inlet pipe 3 is connected to the air inlet threaded pipe 4, and the side of the outer shell 2 is connected to the air outlet pipe 5; a section of the air outlet pipe 5 away from the outer shell 2 is connected to the air outlet threaded pipe 6.

[0027] A positioning groove is provided on the bottom of the positioning member 106 , and multiple groups of positioning members 106 are arranged on both sides of the bottom of the mounting bracket 101 .

[0028] An air-sealing piece is provided on the air inlet threaded pipe 4 , an air-sealing piece is provided on the air outlet threaded pipe 6 , and an anti-slip layer is provided on the bottom of the fixing screw 103 .

[0029] A sliding groove is provided on the inner wall side of the spring housing 8, a sliding protrusion is provided on the side of the spring plate 10, the sliding groove is slidably connected with the sliding protrusion, a transmission groove is provided on the top of the spring housing 8, and the control rod 17 passes through the transmission groove and is connected to the top of the spring plate 10.

[0030] The length of the sealing sliding plate 18 is greater than the length of the control groove, and the width of the sealing sliding plate 18 is greater than the width of the control groove. The top of the sealing sliding plate 18 is in an arc shape, and the sealing sliding plate 18 contacts and squeezes the inner wall of the housing 2.

[0031] The inner wall width of the sealing groove 16 is the same as the width of the sealing ring 13 .

[0032] In this embodiment, the device can effectively improve the accuracy of gas control and reduce the risk of gas leakage. Compared with traditional devices, the device occupies a smaller area and is convenient for concealed installation. At the same time, the structure of the positioning member 106 can facilitate the positioning and installation of the device.

[0033] When the device is in working condition, the combination of the air inlet threaded tube 4 and the air outlet threaded tube 6 at both ends can facilitate the combined connection of the device. The combination of the mounting bracket 101 and the waist-shaped hole 102 can be adjusted according to the specific hole spacing at the installation site. When the mounting bracket 101 is accurately positioned, the structure of multiple sets of fixing screws 103 can facilitate the installation and fixing of the device in the groove, thereby achieving the concealed fixing effect of the device. The structure of the shell 104 can make the surface of the device flush with the wall, avoiding the problem of the ugly appearance of the device. When the gas is not yet turned on, the sealing plate 12 is in contact and squeezed with the rear blocking ring 15.

[0034] When the device is installed and fixed and both ends are stably connected to the pipeline, after the gas is turned on, the stove at the gas outlet end is turned on. At this time, due to the gas outlet of the stove, the air pressure on one side of the gas outlet pipe 5 is reduced, so that there is an air pressure difference on both sides of the sealing plate 12, so that the sealing plate 12 slides toward the gas outlet pipe 5. Since the sealing plate 12 slides towards the gas outlet pipe 5, the spring 9 inside the spring housing 8 is stretched outward. When the spring 9 is stretched, the elastic force of the spring 9 increases, so that the sealing plate 12 forms a new force balance after sliding. When the sealing plate 12 slides between the front blocking ring 14 and the rear blocking ring 15 due to the air pressure difference, the airflow is turned on inside the shell 2, thereby achieving the effect of turning on the device.

[0035] When the stove leaks, the air pressure on one side of the outlet pipe 5 drops sharply due to the large leakage airflow. At this time, the sealing plate 12 slides away from the spring 9 under the action of the air pressure difference. Due to the leakage, the air pressure difference cannot be kept stable like when the stove is in use. Therefore, the sealing plate 12 is in contact and squeezed with the side of the front blocking ring 14, thereby achieving the automatic sealing effect of the device. Before the air pressure in the outlet pipe 5 is restored, the inside of the device is always in a sealed state, avoiding problems such as gas leakage in the device.

[0036] When gas leakage occurs at the supply end, the reverse pressure difference causes the sealing plate 12 to contact and squeeze the rear blocking ring 15, thereby achieving a sealing effect inside the device, thereby preventing the gas inside the pipeline of the device from leaking in the reverse direction.

[0037] The sealing ring 13 on the side of the sealing plate 12 and the sealing grooves 16 on the sides of the front blocking ring 14 and the rear blocking ring 15 can ensure the sealing stability inside the device when the sealing plate 12 and the blocking ring are in contact and extrusion.

[0038] When the device needs to be tested, after the gas sensor is concealed at the outlet pipe 5, the operating rod 19 is manually turned to operate the spring plate 10 to slide manually, thereby realizing the effect of manual opening of the device. When the operating rod 19 of the device slides, the sealing sliding plate 18 slides. The combination of the sealing sliding plate 18 and the control groove can ensure the stability of the sealing of the outer shell 2 while the device is manually turned, thereby preventing gas leakage from the device. The bottom of the sealing sliding plate 18 drives the spring plate 10 to slide through the control rod 17, thereby realizing manual sliding unlocking of the sealing plate 12. At this time, a small amount of gas is discharged from the side of the outlet pipe 5, which is convenient for the sensor to detect, thereby judging whether the current state of the device is working normally.
