Technical Field
The utility model relates to the technical field of self-sealing valve structures for preventing gas leakage, in particular to a self-sealing valve structure for preventing gas leakage.
Background
The self-sealing valve is a valve which automatically opens and closes a valve clack by means of the flow of a medium and is used for preventing the medium from flowing backwards, and the self-sealing valve only allows the medium to flow in one direction and prevents the medium from flowing in the opposite direction. Typically such valves are automatically operated, with the valve flap opening under the pressure of fluid flowing in one direction; when fluid flows in the opposite direction, the self-weight of the valve clack acts on the valve seat by the pressure of the fluid and the self-weight of the valve clack, thereby cutting off the flow. It is not suitable for use with media containing solid particles and having a relatively high viscosity.
In the installation and use process of the existing self-sealing valve, the internal structure is simple and single, the flowing speed of gas and liquid in the valve cannot be regulated, the condition that the gas and the liquid are not sealed in place and leaked can occur in the gas and liquid backflow process, the personal safety of people is damaged, and certain adverse effects are brought to the use process of people.
