A valve that can be finely adjusted

Abstract

The invention relates to the field of valves, specifically a valve that can be precisely adjusted, including a pressure roller carriage, a sealing structure, a chip removal structure, a spray structure, a valve structure, a flow rate control structure and an angle adjustment structure; the valve structure is equipped with There is a flow rate control structure for controlling the water flow velocity; the valve structure is equipped with a spray structure for spraying and cooling the formed winding pipe, and the inside of the valve structure is equipped with an angle adjustment structure for adjusting the angle of the spray structure, which is convenient. The spraying speed of the spraying structure to the pipeline is controlled by the flow rate control structure, which makes the adjustment of the water flow speed more convenient and fast, and at the same time makes the adjusted water flow rate more accurate and stable. At the same time, it is convenient to adjust the relationship between the spraying structure and the valve structure through the angle adjustment structure. The angle between them makes the spray structure adapt to pipes of different sizes, which greatly improves the cooling effect of the spray structure on the pipes and improves the forming quality of the pipes.

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
