Valve capable of changing gas flow direction

Abstract

The invention discloses a valve capable of changing a gas flow direction and relates to the technical field of valves, in particular to a valve capable of changing the gas flow direction. The valve comprises a rotary control device and a transmission control device. The valve body is arranged below the rotary control device which comprises a driving wheel, a fixed sleeve, a transmission gear, a fixed shaft, a built-in rack and a spindle sleeve. The spindle sleeve is arranged in the driving wheel, the fixed shaft is arranged in the transmission gear, and an air flow adjusting device is arrangedbelow the transmission control device. The valve capable of changing the gas flow direction improves the service performance of equipment greatly while increasing a structure. The improved equipmentcan be connected to a plurality of pipelines simultaneously to achieve a splitting operation. A guiding and adjusting operation to gas can be carried out in the valve body, so that the flow directionof gas is changed. Pavement of the pipelines and huge application of the valve bodies are reduced as much as possible, so that the using demand of people is met effectively.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve capable of changing the flow direction of gas. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. The valve can be used to control various types of air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. The flow of fluid has the functions of diversion, cut-off, throttling, check, diversion or overflow and pressure relief, etc. Valves used for fluid control, from the simplest cut-off valve to various valves used in extremely complex automatic control systems There are many varieties and specifications. The nominal diameter of the valve ranges from a very small instrument valve to a valve for industrial pipelines with a diameter of 10m. The control of the valve can adopt a variety of transmission methods, such as manual, electric, hydraulic, pneumatic , turbine...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a valve that can change the direction of gas flow, which solves the problem that the internal and external structures of the existing valves proposed in the above-mentioned background technology are mostly relatively unified, and its functionality is also relatively single. The general valve can only close It is difficult to adjust and control the gas flow direction, resulting in the need for more pipeline laying and more valve bodies to control the pipeline flow in real time during use, and the cost of use is significantly higher. High, and the operation is not fast and convenient enough, and it cannot meet people's needs and other issues.
