PURPOSE: A gas control valve is provided to couple a metallic pin part to a shaft in order to compensate incomplete combustion due to not closely adjusting gas shielding with an eccentric effect due to the loss of centrality from lightening a valve head and a shaft. CONSTITUTION: A gas control valve includes a valve main body, a valve unit, a valve head, and a shaft(7). The valve unit is mounted inside the valve main body. The valve head is integrally attached to the upper end of the valve unit, and the shaft is integrally attached to the lower end of the valve unit. A connector is formed at the lower end of the shaft, and a plunger reciprocates up and down inside a cylinder sleeve. A metallic pin part(2) is coupled to the shaft in order to compensate incomplete combustion due to not closely adjusting gas shielding with an eccentric effect due to the loss of centrality from lightening a valve head and a shaft at the upper side of the plunger. The upper end of the pin part is coupled to the connector(12) of the lower end of the shaft. The other end of the pin part, which is adjacent to the lower end of the shaft, penetrates the hole bored on the center of a diaphragm(3). A support is adjacent to the lower end of the shaft, and is inserted with a disc(4) and an elastic body(5) coupled with a fastening nut(6). |
