Plug valve of novel ignition structure

Abstract

The invention discloses a plug valve of a novel ignition structure and relates to the technical field of gas equipment. The upper end of a valve body is fixedly connected to a valve seat through a bolt, a valve element is movably inserted and fixed to an inner cavity of the valve body, a pulling block is fixedly connected to the outer side wall of the upper end of the valve element in a clamping manner, a limiting plate is fixedly connected to the outer side wall of the bottom end of a rotating shaft in a clamping manner, the rotating shaft is inserted and fixed to an inner cavity of the valveseat through the limiting plate, the bottom end of the rotating shaft is inserted and fixed to an open slot in the upper end of the valve element, a connecting spring I is fixedly mounted between thepulling block and the limiting plate, and an igniter is fixedly mounted in the inner cavity of the valve seat through a bolt. In a pushing rotating process of the rotating shaft, the limiting plate is pushed to push to rotate to strike the igniter, so that the igniter works to generate a current, and then the rotating shaft is loosened to reset to rotate a small fire position anticlockwise so asto finish a working process of the plug valve. The quantity of accessories is reduced effectively, the product is simple in structure and easy to process, and the plug valve is low in manufacturing cost and convenient in after-sales repair.

Description

technical field [0001] The invention belongs to the technical field of gas equipment, and in particular relates to a plug valve with a novel ignition structure. Background technique [0002] Gas stoves are more common in daily life. There are ignition switches and cock valves installed on gas stoves. The plug body is used as the opening and closing part of the valve. The plug body rotates with the valve stem to realize the opening and closing action. Through the rotation, the channel port on the valve plug is the same as or separated from the channel port on the valve body to realize opening or closing. . [0003] The existing cock valve rotates 90 degrees by pressing down the rotating shaft, and the pulling block pulls the hammer, and the hammer is pushed backward. When the rotation reaches 90 degrees, the pulling block is separated from the hammer, and the hammer moves forward under the action of the spring force. After hitting the electrons, an electric current is gener...

Problems solved by technology

[0003] The existing cock valve rotates 90 degrees by pressing down the rotating shaft, and the pulling block pulls the hammer, and the hammer is pushed backward. When the rotation reaches 90 degrees, the pulling block is separated from the hammer, and the hammer moves forward under the action of the spring force. After hitting the electrons, the current flow is generated from the surface, which makes the valve body produce an ignition effect. Its structure is complicated, the number of accessories is large, the processing technology is complicated, and the processing cost is high.
