Double-gas source valve with adjustable gas door

Abstract

The invention relates to a double-gas source valve with an adjustable gas door. The double-gas source valve is connected with a gas interface through a joint and comprises a gas valve body, a nozzle, the gas interface, a venturi tube, an air window and the gas door, wherein the nozzle and the gas interface are arranged on the gas valve body, the venturi tube is sheathed on the nozzle, the air window is arranged on the venturi tube, and the gas door is arranged at the air window and can be used for rotatably adjusting the size of the air window; the double-gas source valve also comprises an air door adjustment device, a supporting point and a linkage device; the air door adjustment device is connected with the air door, the supporting point is arranged on the gas valve body, the linkage device is connected with the supporting point and can rotate around the supporting point, one end of the linkage device is movably connected with the air door adjustment device, and the other end of the linkage device is arranged at the side part of the gas interface of the gas valve; the gas interface is connected with the joint in a matching manner; and when the joint is connected into the gas interface, the side part of the joint props against the linkage device to drive the linkage device to rotate, thereby driving the air door adjustment device to drive the air door to rotate. When different joints are connected into the double-gas source valve, a linkage rod is touched, so that the size of the primary air door and the proportion of gas to air are changed and the best burning effect is achieved.

Description

technical field [0001] The invention relates to a dual gas source gas valve, more precisely a dual gas source integrated valve with an adjustable damper. Background technique [0002] The present invention is used for dual-gas source gas valves. A general dual-gas source gas valve has two gas source gas interfaces. When different interfaces are connected to corresponding gas connectors, the gas connectors will touch the relevant parts in the integrated valve, thereby Change the working state of the control valve, such as changing the pressure to the nozzle. However, different gas components are different, and the oxygen consumption during combustion is also different. If the relative ratio of gas and air is not adjusted during the mixing process, the combustion effect will be unsatisfactory. Contents of the invention [0003] Due to the above-mentioned shortcomings of the prior art, the present invention proposes an adjustable damper dual gas source integrated valve, whic...
