Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a micro-balance valve for gas transmission. Background Art

[0002] A balancing valve is a valve with special functions. There is nothing special about the valve itself, except that its function and location are different. In some industries, due to the large pressure difference or flow difference between the media (various flowable substances) in various parts of the pipeline or container, in order to reduce or balance the difference, a valve is installed between the corresponding pipelines or containers to adjust the relative balance of pressure on both sides, or to achieve flow balance by diversion. This valve is called a balancing valve.

[0003] During use of the existing balancing valve, the user needs to measure the pressure difference and then manually adjust the opening and closing of the balancing valve to control the flow on both sides of the valve body. The operation process is complicated and requires the staff to spend a lot of time to adjust, which affects work efficiency. In addition, the adjustment accuracy is difficult to control, which affects the use effect of the balancing valve.

[0004] To this end, a micro balancing valve for gas transmission is proposed. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting the adjustment component, the user can monitor the air pressure at both ends of the valve tube body through the pressure gauge. When a pressure difference occurs at both ends of the valve tube body, the motor is started through the terminal, and the motor can drive the movable rod to rotate. At this time, the sealing disc at the bottom of the movable rod can rotate in the through hole. The flipping angle of the sealing disc can be adjusted by adjusting the number of rotations of the motor, which can change the flow of gas in the through hole and facilitate the adjustment of the pressure difference at both ends of the valve tube body.
