Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a valve that is easy to adjust. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in extremely complex automated control systems, with a wide variety of types and specifications.

[0003] Traditional valves suffer from poorly designed regulating mechanisms, resulting in unclear tactile feedback during adjustment and difficulty in accurately judging valve opening, especially in applications requiring precise flow control, thus failing to meet production process requirements. Furthermore, some valves require significant operating force for adjustment, which can lead to operator fatigue over prolonged use and compromises adjustment accuracy. Additionally, the rotating parts, being critical components for valve operation, are prone to damage due to wear and corrosion after extended use. The connection between the rotating parts and the valve body in traditional valves is complex, typically requiring the valve to be removed from the pipeline for replacement, resulting in cumbersome procedures, high maintenance costs, and prolonged equipment downtime, disrupting production continuity. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the valve adjustment mechanism is poorly designed, the adjustment process is not clear, and it is difficult to accurately judge the valve opening. Therefore, this invention proposes a valve that is easy to adjust.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a valve that is easy to adjust, comprising a valve body, a ball sleeve inside the valve body, a ball valve embedded inside the ball sleeve, a first circular hole at the top of the valve body, a second circular hole at the top of the ball sleeve, a valve stem embedded inside the first and second circular holes, a groove at the top of the ball valve, the bottom of the valve stem embedded in and adapted to the groove, a rotating part covering the top of the valve body, a first circular groove at the bottom of the rotating part, a square groove at the top inner wall of the first circular groove near the center, a square plate embedded inside the square groove, the bottom of the square plate being fixedly connected to the top of the valve stem, a trapezoidal arc plate fixedly connected to the inner wall of the first circular groove, a fan-shaped plate fixedly connected to the top of the valve body at the second circular hole, the fan-shaped plate being located inside the first circular groove, a second circular groove at the top of the rotating part, a stud penetrating through the bottom inner wall of the second circular groove, the bottom of the stud being embedded in the top of the square plate and threadedly connected to it.

[0006] Preferably, one end of the ball sleeve is embedded with an annular cover, and an annular groove is formed inside the ball sleeve and near one end and the inner wall of the annular cover, and a sealing ball gasket is embedded inside the annular groove.

[0007] Preferably, the first circular hole and the second circular hole are aligned with each other.

[0008] Preferably, a first sealing ring is embedded on the surface of the valve stem at both the first and second circular holes, and the first sealing ring is in contact with the inner wall of the first and second circular holes.

[0009] Preferably, a limiting ring groove is formed inside the second circular hole, and a limiting ring plate is embedded and rotatably connected inside the limiting ring groove. The limiting ring plate is fixedly connected to the valve stem.

[0010] Preferably, the central angle of the trapezoidal arc plate is 180 degrees, and the central angle of the sector plate is 90 degrees.

[0011] Preferably, the top of the rotating component is embedded with and snapped together with an arc-shaped cover.

[0012] Preferably, the valve body is provided with a first connecting pipe and a second connecting pipe at both ends, and a screw ring sleeve is installed at both ends of the valve body.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the rotating component and the valve stem are connected by a structure such as a square plate and a square groove. When the rotating component is rotated, it can directly drive the valve stem to rotate, thereby facilitating the control of the opening and closing of the ball valve. At the same time, the trapezoidal arc plate and the fan-shaped plate can accurately control the degree of opening and closing of the ball valve, thereby achieving precise regulation of the fluid flow rate.

[0017] 2. In this utility model, the rotating component is connected to the valve body through components such as studs. When the rotating component is damaged, there is no need to disassemble the valve from the pipeline. Simply use a simple tool to unscrew the studs, and the rotating component can be quickly removed from the valve body for replacement. This greatly shortens the maintenance time, reduces maintenance costs, and ensures the normal operation of the equipment and the continuity of production. Attached Figure Description
