New description: [New technical field] This creation is related to a gas switch, especially a gas switch that can be used for various pressure gas. [Prior Art] In recent years, many gas stoves have begun to use higher pressure gas as gas supply gas to improve the firepower of the burner and improve cooking efficiency. The use of high pressure gas and gas as fuel can increase the firepower of the burner. Eli quickly fry or cook food to create a delicious dish, but it is easy to form a gas leak in the gas supply pipe or gas switch' to endanger the safety of use. As is known, the gas switch structure widely used at present is generally provided with a rotatable conical closure inside the gas switch body, and the through hole is preset on the closed body, so that the closed sub-option can be selected. Rotating to an angle and consuming with the gas supply pipe on the gas switch body, thereby dividing the gas gas into the gas burner head to provide combustion, and thereby controlling the gas supply volume to adjust the burner flame size. Generally, an elastic thrust is applied to the large end face of the cone of the closed body, so that the conical surface of the closed body is closely attached to the hole wall of the gas valve seat to prevent gas from leaking from the gap of the bonding surface; the gas switch The design of the structure is basically no problem when the gas is supplied by the low-pressure gas. However, when the gas is supplied in the medium and high-pressure gas, the strong high-pressure gas sometimes causes the conical closed body to face the large end face of the cone (ie, The displacement of the end face to which the elastic thrust is applied causes the conical surface of the closed body to be in close contact with the wall of the gas valve seat to form a problem of gap leakage. If the displacement of the closed cone's ® cone is increased to the increased elastic thrust in order to prevent the closure from being displaced by the gas pressure, the conical surface of the closure will be excessively attached to the gas valve seat. On the wall of the hole, the frictional resistance is doubled and the rotation operation is not carried out' even without the smooth operation of the gas switch. [New content] This creation provides a gas switch suitable for various gas pressures. It mainly changes the conventional gas __ substructure to be used with a resilient sealing unit to operate the ball, and the elastic unit makes the sealing unit Close to the ball-shaped closed-faced ball can reach difficult (four), so that the tile can be suitable for high-pressure gas occasions and because it has not changed, the main structure design, _ main components are no longer needed In addition, Cong manufactures, so it can reduce the cost of production.
