A reliable closed gas safety valve

By introducing an elastic element into the gas safety valve to provide restoring force to the drive control components, the problem of poor sealing caused by the inability of the hot metal sheet to return to its original shape is solved, reducing the risk of gas leakage and improving safety.

AI Technical Summary

Technical Problem

The hot metal strip of existing gas safety valves may not be able to return to its original shape after long-term use, causing the sealing block to fail to fit tightly with the regulating seat, resulting in a gas leakage safety hazard.

Method used

An elastic element is used to provide the restoring force for the vent hole of the sealing adjustment seat of the drive control component, ensuring that the drive end of the drive control component can reliably seal the vent hole and reduce the risk of gas leakage.

Benefits of technology

The restoring force provided by the elastic element eliminates the phenomenon that the drive control component cannot provide the initial sealing force after long-term use, reducing the risk of gas leakage and improving safety.

Abstract

The application discloses a reliable gas safety valve, which comprises a valve body, a driving control part, an adjusting seat and an elastic part. The valve body is internally provided with a valve cavity. The valve body is provided with a gas outlet joint. The gas outlet joint comprises a ventilation cavity. The ventilation cavity can be communicated with the valve cavity. The driving control part is arranged in the valve cavity and is used for controlling whether the gas outlet joint has gas flow. The adjusting seat is at least partially arranged in the ventilation cavity. The adjusting seat is provided with a ventilation hole. The ventilation hole can communicate the ventilation cavity with the valve cavity. The driving control part comprises a driving end part. The driving end part is arranged in correspondence with the ventilation hole and can block or open the ventilation hole. The elastic part can provide a restoring force for the driving control part to block the ventilation hole. The restoring force provided by the elastic part is smaller than the opening force of the driving end part. The gas safety valve can reliably block the ventilation hole by the driving end part of the driving control part, reduces the risk of abnormal state that the ventilation hole cannot be sealed, and reduces the risk of gas leakage.
