Abstract

A gas transmission switch comprises a T-shaped tee joint body. A bushing and a plug are installed at the two ends of a cross arm of the T-shaped tee joint body respectively, and a fixed coincidence piece is installed at the inner end of the bushing in a sealed mode. A lead screw sequentially penetrates through the plug and the fixed coincidence piece in a sealed mode and then is in clearance connection with the bushing, and a movable coincidence piece is fixedly connected to the lead screw and makes contact with the fixed coincidence piece. Via holes which are arranged in a staggered mode areformed in the fixed coincidence piece and the movable coincidence piece. A baffle is fixedly connected to the portion, above the inner end of the plug, of the lead screw,the portion, between the baffle and the inner end of the plug, of the lead screw is sleeved with a compression spring, a hand wheel is mounted at the end, at the outer end of the plug, of the lead screw , and the plug is movably mounted at one end of the cross arm of the T-shaped tee joint body. By means of the movably connected plug, the pressing degree between the fixed coincidence piece and the movable coincidence piece isadjusted, and gas in a pipeline can be controlled and used according to needs.

Description

technical field

[0001] The invention relates to the field of a water gas heating switch, in particular to a gas transmission switch. Background technique

[0002] At present, the gas transmission switches on the market are mainly ball valves and gate valves. Since straw gas is self-made gas, the gas contains water vapor, smoke, tar, etc., which are easy to deposit on the wall of the switch valve, causing the above-mentioned conventional switches to be easily blocked and jammed. Living, maintenance and repair is also very inconvenient. Contents of the invention

[0003] The invention provides a gas transmission switch, which solves the problem that ball valves and gate valves in the current market cannot transport slag gas.

[0004] In order to achieve the above goals, the following technical solutions are adopted:

[0005] A gas transmission switch, comprising a T-shaped tee body, the two ends of the cross arm of the T-shaped tee body are respectively equipped with a bus...

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing.

[0012] refer to figure 1 , a gas transmission switch, including a T-shaped three-way body, the two ends of the cross arm of the T-shaped three-way body 5 are respectively equipped with a bushing and a plug, and the inner end of the bushing 1 is sealed and fixed with a overlapping piece 2; the screw rod 6 is in turn After the seal passes through the plug 8 and the fixed overlapping piece 2, it is connected to the gap of the bushing 1. The movable overlapping piece 4 is fixed on the screw rod 6 and is in contact with the fixed overlapping piece 2. The fixed overlapping piece 2 and the movable overlapping piece 4 have mutual Displaced via holes; a baffle 7 is fixedly connected to the screw rod 6 above the inner end of the plug 8, and a compression spring 8 is set on the screw rod 6 between the baffle plate 7 and the inner end of the plug 9, and the screw rod 6 is in the The t...
