Mechanical air-gas linkage valve

Abstract

The invention relates to a mechanical air-gas linkage valve. The mechanical air-gas linkage valve comprises a T-shaped valve body and a ball valve body which are relatively fixed; the T-shaped valve body comprises a T-shaped shell, a total combustion-supporting air valve body, a first fixed valve plate, a second fixed valve plate, a first movable valve plate, a second movable valve plate and a linkage shaft, wherein the total combustion-supporting air valve body, the first fixed valve plate, the second fixed valve plate, the first movable valve plate, the second movable valve plate and the linkage shaft are arranged in the T-shaped shell; opening and closing of an air inlet passage formed between the first fixed valve plate and the first movable valve plate are opposite to opening and closing of a pressure relief passage formed by the second fixed valve plate and the second movable valve plate; the ball valve body comprises a ball valve shell and a ball body; a strip-shaped through hole penetrating through the ball body is formed in the ball body; the upper end and the lower end of the ball body are connected to the linkage shaft and a knob correspondingly; and opening and closingof the ball valve body are the same as opening and closing of the air inlet passage formed by the first fixed valve plate and the first movable valve plate. According to the mechanical air-gas linkagevalve, the gas flow and the combustion-supporting air flow can be synchronously adjusted by controlling the knob of the ball valve body, an air outlet passage and the pressure relief passage which are synchronously adjusted can also guarantee the stable supply of combustion-supporting air, the mechanical air-gas linkage valve is a pure mechanical adjusting device and is safe, stable and convenient to use.

Description

technical field [0001] The invention relates to a mechanical fuel valve and a blast valve, in particular to a linkage structure of the fuel valve and the blast valve. Background technique [0002] In addition to the fuel, the large-scale stove also needs a large amount of combustion-supporting air to be sent by the blower. The conventional fuel valve and the air valve are two independent parts, and they need to be operated separately at the same time during use, which is inconvenient to use. When the air valve does not move, the adjustment range of the gas valve is too small, which may easily lead to insufficient combustion. [0003] At present, electromagnetic valves are also applied to the furnace of gas pipes and blast pipes, and the size of fuel and blast is controlled electronically. However, solenoid valves are precision instruments, and the temperature has a great influence on the working conditions of the furnace. It is troublesome to use and maintain. [0004] In...

Problems solved by technology

Conventional fuel valve and air valve are two independent parts, which need to be operated separately at the same time, which is inconvenient to use

When the air valve does not move, the adjustment range of the gas valve is too small, which may easily lead to insufficient combustion

[0003] At present, electromagnetic valves are also applied to the furnace of gas pipes and blast pipes, and the size of fuel and blast is controlled electronically. However, solenoid valves are precision instruments, and the temperature has a great influence on the working conditions of the furnace. Troublesome to use and maintain

[0004] In addition, the above two control methods also have a common defect. The flow ratio of fuel and blast should be considered during the operation of the two valves, which is difficult to control precisely.
