Abstract
Disclosed is a pressure controller of the coal gas valve. The controller comprises a valve body, a valve lever, a valve lever support and a press spring. The major points are that gas inlet and outlet cavities are respectively arranged at two sides of the valve body. An inward withdraw way of internal wall at the coal gas outlet port of the valve body forms a circular convex platform. An external wall at one side of the coal gas outlet port of the valve body is provided with an outer thread and a circular groove with sealing ring. A side of the valve lever is extended to the outside and is provided with a umbrella type skeleton. The valve lever support is in a cylinder-shaped, one side of the valve lever is an open end and the other side is a closed end. A circle hole penetrating from the valve lever is opened on the closed end face. The valve lever support is arranged in the valve body. The external wall of the valve body is tightly coordinated with the internal wall of the valve body. The valve lever passes through the circle hole on the valve lever support and the valve lever extended part is inserted into the cavity of the valve body. The umbrella type skeleton of the valve lever is located in the cylinder of the valve rod frame and the valve lever in the cavity of the valve body is wrapped with a press reed. The utility model can automatically close the gas source as the gas is leaked, greatly improving the gas security in use and giving the customer the safe sense.
Description
(1) technical field
The utility model relates to a kind of valve member, particularly relates to a kind of gas relief valve pressure controller, and this pressure controller is installed in the ingress of Safety valve body, utilizes the switching of the pneumatic control valve door in the pipeline.
(2) background technique
Gas relief valve is a requisite crux matching parts on the gas appliance.Family uses coal gas at present, getting more and more of liquid gas, in use, occur sometimes forgetting closing valve or stove fire being extinguished because of boiling water in the pot overflows because of the gas appliance leakage or because of careless, cause empty race accidents such as coal gas, liquid gas leakage, close as untimely, cut off source of the gas and call a halt, bring serious harm will for people's life and property.And the gas leakage warning device that market provides can only point out people to take emergent accordingly protective measures in the mode of alarm equipment alarm the information of gas leakage, but can not immediately, automatically stop the empty race accidents such as leakage of coal gas, thereby be difficult to guarantee coal gas user's safety.
(3) summary of the invention
Sign in above-mentioned reason, the utility model provides a kind of gas valve pressure controller that can cut off source of the gas when gas leakage automatically.
The technological scheme that adopts:
Gas valve pressure controller of the present utility model comprises valve body, valve rod, valve rod support and stage clip.Valve body is the cavity body that both sides are arranged with gas inlet and gas exit, and the inside undergauge of inwall at the gas exit place of valve body forms an annular boss, the annular groove that the outer wall of valve body gas exit one side is provided with outside thread and inserts for seal ring; One epitaxial lateral overgrowth of valve rod is provided with umbrella skeleton, and the valve rod support is cylindric, and the one side is an opening end, opposite side is a closed end, and offer a circular hole that supplies valve rod to penetrate on the end face of its closed end, the valve rod support is arranged in the valve body, and the inwall of its outer wall and valve body closely cooperates; Valve rod passes the circular hole on the valve rod support, and its portion of passing is positioned at the chamber of valve body, and its umbrella skeleton is positioned at the cylinder of valve rod support, is positioned on the endoceliac valve rod of valve to be equipped with a stage clip.
The interior sidewall surface of the annular boss of gas exit one side is intilted domatic on the above-mentioned valve body.
The middle part of the outer side surface of above-mentioned valve rod support Closed End convexes with the baffle ring that a voltage supply spring one side is inserted.
Working principle
Gas pressure controller of the present utility model is installed in the gas relief valve that connects fuel gas pipeline and gas range, when the operation gas range, when the air pressure in the fuel gas pipeline reaches regulation numerical value, leave the normal slit of passing through that gives gas between the Closed End of the umbrella skeleton of valve rod one side and valve rod support one side, the stage clip of this moment is not compressive state yet, coal gas can from the gas inlet of valve body on the one side closed end face of valve rod support circular hole and arrive gas-fired boiler through the gas exit of valve body, (abnormal state) valve rod is pushed when the air pressure in the fuel gas pipeline surpasses the regulation permitted value, and the umbrella skeleton that passes through valve rod one side seals the gas exit on the valve body, block the outflow of combustion gas, thereby prevented the leakage of combustion gas.
The utility model can be arranged on the ingress of gas safety valve body, utilize the air pressure in the pipeline to promote moving of valve rod, thereby can when gas leakage, close source of the gas automatically, and then improve the Security that coal gas uses widely, the sense of security is provided for the coal gas user.
