Valve capable of being precisely adjusted

Abstract

The invention relates to the field of valves, in particular to a valve capable of being precisely adjusted. The valve comprises a pressing wheel sliding frame, a sealing structure, a scrap removing structure, a spraying structure, a valve structure, a flow speed control structure and an angle adjusting structure; the valve structure is provided with the flow speed control structure used for controlling the water flow speed; the valve structure is provided with the spraying structure used for spraying and cooling the formed winding pipe, and the angle adjusting structure used for adjusting theangle of the spraying structure is arranged in the valve structure, so that the spraying speed of the spraying structure on the pipeline is conveniently controlled through the flow speed control structure, and the adjustment of the water flow speed is more convenient and faster; and meanwhile, the flow speed of the adjusted water flow is more accurate and stable, the angle between the spraying structure and the valve structure can be conveniently adjusted through the angle adjusting structure, so that the spraying structure is suitable for pipelines of different sizes, the cooling effect of the spraying structure on the pipelines is greatly improved, and the forming quality of the pipelines is improved.

Description

technical field [0001] The invention relates to the field of valves, in particular to a valve capable of precise adjustment. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. The pressure relief valve is composed of needle valve, pressure gauge, main valve, pilot valve and connecting pipe, etc. It can be opened and closed automatically according to the working pressure of the system. It is generally installed on the equipment or pipeline of the closed system to protect the safety of the system, for example: In the production process of the winding pipe, the valve and the bellows are used to spray and cool the pressure roller to prevent the material from sticking to the pressure roller and to make the forming...

AI Technical Summary

Problems solved by technology

[0003] However, most of the valves connected to the bellows are installed on the side wall of the water tank, and it is easy to wet the operator when adjusting the water flow rate. At the same time, the accuracy of the adjustment is relatively poor, which is not convenient for quick adjustment. At the same time, the stability of the bellows is poor. After connecting with the valve, it is also easy to touch and bend under the change of water pressure, which makes the effect of cooling spray less. The bonding effect of the strip, when the water flow is small, the cooling effect on the rubber strip and the pressure wheel is poor, and the rubber strip is easily bonded to the pressure wheel, which affects the extrusion molding effect of the pressure wheel on the winding tube
