A gas shut-off valve
By introducing sealing elements and elastic components into the gas shut-off valve, the gas passage can still be reliably blocked even when the drive mechanism fails, solving the problem of insufficient safety and reliability of existing gas shut-off valves and improving the safety and reliability of the system.

AI Technical Summary
Technical Problem
Existing gas shut-off valves are highly dependent on the drive mechanism, which results in low safety and reliability, and cannot meet user needs.
Method used
A gas shut-off valve is designed, comprising a valve body, a drive mechanism, a sealing element, and an elastic component. The elastic component causes the sealing element to abut against the sealing gasket to achieve both blocking and opening of the gas passage. The drive mechanism only drives the sealing element to deviate from the gas passage when needed.
Benefits of technology
Even when the drive mechanism fails, it can still ensure the reliable cut-off of the gas passage, improving safety and reliability and avoiding the problem of the passage not being able to be cut off due to drive mechanism failure.

Abstract
This utility model discloses a gas shut-off valve, relating to the field of valves. It includes a valve body and a drive mechanism. The valve body has an inlet, an outlet, and a gas passage. A shut-off assembly is located within the valve body. The shut-off assembly includes a sealing element, an elastic component, and a sealing gasket located in the gas passage. Because the shut-off assembly is located within the valve body, the elastic component presses the sealing element against the sealing gasket in the gas passage, thus blocking the gas passage. Therefore, when gas flow is required, simply activating the drive mechanism to move the sealing element away from the gas passage allows the gas passage to flow. When the gas passage needs to be shut off, the drive mechanism stops, and the elastic component, due to its elasticity, presses the sealing element against the sealing gasket, thus blocking the gas passage. Therefore, it eliminates the problem of the gas passage not being shut off if the drive mechanism is damaged, resulting in higher safety and reliability, and meeting user needs.
