Gas connector with pressure stabilization and super-flow protection functions

Abstract

The invention discloses a gas connector with pressure stabilization and super-flow protection functions. According to the gas connector, when the pressure of external fed air is too high, an ejector rod is moved towards a first piston under action of the air feeding thrust, the airflow space between a bulge loop part and a first valve port is gradually deceased, and accordingly, the flow rate of the first valve port is not increased suddenly; after the pressure of the external fed air is lowered, the air feeding thrust to the ejector rod is decreased, at the moment, a first spring presses theejector rod to move reversely through the first piston under the elastic reset action of the first spring, thus, the airflow space between the bulge loop part and the first valve port is gradually increased, accordingly, the flow rate of the first valve port is not decreased suddenly, and pressure stabilization control is facilitated; and when the super-flow phenomenon occurs to the outer end of asecond valve port, if a gas appliance connected with the gas connector is subjected to too fast flame combustion, a second piston overcomes the elastic force of a third spring under action of high negative pressure so that the second valve port can be sealed, only direct-communicating small holes are open for ventilation, thus, flames of the gas appliance become low fire, and the super-flow protection function is achieved.

Description

technical field [0001] The invention relates to a gas connector with the functions of voltage stabilization and overflow protection. Background technique [0002] In daily life, people often use gas appliances for cooking, heating, lighting, etc. Therefore, gas safety is a problem that people attach great importance to. At present, the gas appliances on the market generally adopt a simple connection structure with the gas source, which cannot deal with some emergencies. For example, the connectors between some gas appliances and the gas source do not have the current limiting function. When the output air flow is too high, the combustion flame of the gas appliance will become abnormally high, which is prone to dangers such as overloading of the gas appliance, burning out or even fire; in addition, when a fire occurs, the general gas appliance and its connection structure cannot The gas flow is cut off at the root, and the safety is poor. [0003] Therefore, how to overcome...
