Water cooling device, flow control device and cooling method of flow control device

Abstract

A flow control device comprises a flow control valve and a water cooling device; the flow control valve comprises a valve body and a flow adjusting piece, and the flow adjusting piece is arranged in the valve body; the water cooling device comprises a shell, the shell is arranged on the outer wall of a valve body of the flow control valve, the inner wall of the shell and the outer wall of the valve body jointly define a cavity, the shell is provided with at least one water inlet and at least one water outlet, and at least one water inlet and the at least one water outlet are communicated with the cavity. After cooling water is injected into the cavity from at least one water inlet, the cooling water is in contact with the outer wall of the valve body to absorb heat energy of the outer wall of the valve body, and then the cooling water with the heat energy is discharged from at least one water outlet to achieve the purpose of reducing the temperature of the valve body.

Description

technical field [0001] The present invention is related to a cooling device; in particular, it refers to a water cooling device suitable for a flow control valve. Background technique [0002] The known flow control valve is a control switch assembled on the pipeline to control the flow of fluid in the pipeline or change the flow and direction of the fluid. [0003] In response to different operating environments and fluid types, the structural design and material usage of flow control valves are significantly different. For example, most of the common flow control valves on the market are made of plastic materials or metal materials. Flow control valves made of plastic materials have the advantages of simple manufacture and low price. However, flow control valves made of plastic materials Valves cannot be used in high temperature environments. [0004] Compared with the flow control valve made of plastic material, the flow control valve made of metal material can be used ...

Problems solved by technology

[0003] In response to different operating environments and fluid types, the structural design and material usage of flow control valves are significantly different.

For example, most of the common flow control valves on the market are made of plastic materials or metal materials. Flow control valves made of plastic materials have the advantages of simple manufacture and low price. However, flow control valves made of plastic materials The valve cannot be used in high temperature environment

[0004] Compared with the flow control valve made of plastic material, the flow control valve made of metal material can be used in a higher temperature environment by taking advantage of the high temperature resistance of the metal material itself, but the high temperature environment still has advantages for the flow control valve. Quite destructive, for example, when the flow control valve is placed in a high-temperature environment for a long time, it is easy to cause the rapid deterioration of the leak-proof parts inside the flow control valve, which will cause the problem of loss of sealing

[0005] In addition, in order to reduce the temperature of the flow control valve, a water-cooling tube can also be installed adjacent to the flow control valve. After the cooling water flowing in the water-cooling tube absorbs the heat energy in the air outside the tube wall of the water-cooling tube, the heat energy It is separated from the flow control valve, but because there is usually a gap between the water-cooled pipe and the flow control valve, there is a problem of poor cooling effect. In summary, the existing flow control valve is still not perfect in the design of temperature control Perfect, room for improvement
