Description

Technical Field

[0001] This utility model relates to the field of gas valve technology, and in particular to a gas stove anti-leakage valve. Background Technology

[0002] Gas stove valves are a new type of safety accessory for gas pipeline projects. They are used to cut off, connect, and regulate the gas in the pipeline, and have good control characteristics and sealing performance.

[0003] However, during use, the sealing performance of the connection between the gas stove valve and the gas pipeline is often unsatisfactory. The sealing performance of this connection directly affects the safety and stability of the entire gas system. Existing gas stove valves often have poor sealing at the connection, leading to easy gas leaks. Furthermore, these leaks often fail to alert the user, posing a potential safety hazard and constantly threatening the user's safety. Utility Model Content

[0006] The sealing cap is also equipped with a handle, and a sealing plate is provided at the lower end of the sealing cap;

[0007] The upper ends of the first and second housings are provided with grooves, which are sealed to the sealing plate.

[0008] Furthermore, the alarm components include a PLC controller and an infrared sensor and an alarm light controlled by the PLC controller. The infrared sensor and the PLC controller are located inside the second housing, while the alarm light is located outside the second housing.

[0009] Furthermore, a handle is provided at the upper end of the gas valve, a gas pipeline is connected to the gas valve, a connection mechanism is provided between the gas valve and the gas pipeline, and a limit ring is also provided on the gas pipeline.

[0010] Furthermore, ear plates are provided on both sides and the bottom of the first and second housings.

[0011] Furthermore, the cross-sections of the first and second shells are U-shaped.

[0012] Furthermore, annular shells are provided on both sides of the first and second shells. The annular shells are located below the ear plates. Annular grooves corresponding to the limiting rings are provided inside the annular shells, and sealing gaskets are provided on the annular grooves.

[0013] Furthermore, the connecting mechanism includes a first flange, a sealing ring, a sealing groove, and a second flange. The second flange is mounted on the gas valve, and the first flange is mounted on the gas pipeline. A sealing ring is provided between the first flange and the second flange.

[0014] Furthermore, both the first and second flanges have sealing grooves on the side closest to the sealing ring.

[0015] Furthermore, the sealing ring is provided with a first through hole, the sealing groove on the second flange is provided with a corresponding second through hole, and the sealing groove on the first flange is provided with a corresponding third through hole. Bolts are used to fix the first flange, the sealing ring, and the second flange in sequence through the third through hole, the first through hole, and the second through hole.

At the same time, a sealing gasket is set in the annular groove, and a sealing ring is set between the first flange and the second flange. Then, the first flange and the second flange are bolted together to achieve a multi-seal effect, prevent gas leakage, and enhance the sealing performance of the valve.

[0017] Different gas molecules absorb infrared light of different wavelengths. By measuring the absorption of infrared light at a specific wavelength using an infrared sensor, it is possible to determine whether there is a leak of a specific gas. The monitored data signal is then transmitted to the PLC controller, which controls the alarm light to sound an alarm and flash, thereby serving as a warning and preventing the accident from escalating.
