Description

Technical Field

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

[0002] Gate valves are a type of on / off valve commonly used in pipeline systems, widely applied in industries such as petroleum, chemical, power, and water supply and drainage, for controlling the opening and closing of media. The main function of a gate valve is to cut off or connect fluid flow, controlling the flow rate in the pipeline by the up-and-down movement of the gate. Due to their simple structure and good sealing performance, gate valves are widely used in large-diameter, high-pressure pipeline systems. However, existing traditional gate valves have certain shortcomings, particularly in terms of adjustment accuracy, ease of operation, and control precision, limiting their application in some demanding situations.

[0003] First, existing gate valves have problems with the accuracy of opening and closing control. Traditional gate valves typically rely on handwheels, gears, hydraulic or electric actuators for operation. However, due to friction during the opening and closing process, insensitive operation, or equipment aging, existing gate valves often struggle to achieve precise opening and closing control. In applications requiring fine adjustment of flow or pressure, traditional gate valves often cannot provide sufficiently precise control, potentially leading to unstable flow control or over-switching.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a gate valve that is easy to adjust. Utility Model Content

[0005] The purpose of this invention is to provide a gate valve that is easy to adjust, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gate valve technology solution that is easy to adjust includes:

[0008] The valve body has a channel running through both sides inside, and a gate groove is opened on the inner wall of the channel.

[0009] The valve seat is fixedly installed on the top of the valve body, and the valve seat is provided with a gate guide port that communicates with the gate groove;

[0010] Valve stem support, mounted on the valve seat;

[0011] The rotary wheel is rotatably mounted on the valve stem bracket;

[0012] The screw is coaxially threaded to the impeller and extends into the valve stem holder.

[0013] The gate is located in the gate slot, with its top connected to the screw, and its two sides embedded in the gate slot and slidingly engaged with the gate guide opening.

[0014] As a preferred technical solution, the valve body has an inwardly inclined channel ramp at the channel inlet to guide and mitigate impact.

[0015] As a preferred technical solution, the valve body is provided with a valve body fixing connection part on the outer wall around the valve body, and the valve stem frame is detachably connected to the valve seat by an assembly bolt.

[0016] As a preferred technical solution, the edge of the gate is wrapped with a sealing strip, which is pressed against the gate groove to achieve a seal.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention relates to a gate valve that is easy to adjust. It features a rotating wheel and a screw working together. Rotating the wheel drives the screw to move up and down, which in turn causes the gate to slide up and down within a gate groove, thus controlling the opening and closing of the passage. Due to the threaded connection, there is a proportional relationship between the rotation angle of the wheel and the movement distance of the gate, enabling relatively precise flow control. Furthermore, the gate guide design makes the gate more stable during movement, reducing the risk of decreased control accuracy due to insensitive operation or equipment aging.

[0023] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a gate valve technical solution that is easy to adjust: it includes a valve body 1, which has a channel 12 that runs through both sides inside, and a gate groove 121 is opened in the inner wall of the channel. The inlet of the channel of the valve body 1 is provided with an inwardly inclined channel slope ring 101 to guide and reduce impact.

[0025] like Figure 2 As shown, valve seat 13 is fixedly installed on the top of valve body 1, and valve seat 13 is provided with gate guide port 131 communicating with gate groove 121. Valve stem bracket 2 is disposed on valve seat 13, and rotating wheel 21 is rotatably mounted on valve stem bracket 2. Screw 22 is coaxially threadedly connected to rotating wheel 21 and extends into valve stem bracket 2. Gate 23 is located in gate groove 121, its top is connected to screw 22, and its two sides are embedded in gate groove 121 and slide in cooperation with gate guide port 131.

[0026] like Figure 3 As shown, the valve body 1 has a valve body fixing connection part 11 on its outer wall, and the valve stem bracket 2 is detachably connected to the valve seat 13 by an assembly bolt 24. The use of the assembly bolt 24 makes the connection between the valve stem bracket 2 and the valve seat 13 more convenient, and facilitates maintenance and replacement of parts.

[0027] In a preferred embodiment, a sealing strip is wrapped around the edge of the gate 23 and pressed against the gate groove 121 to achieve a seal. The use of the sealing strip can improve the sealing performance of the gate valve and ensure effective prevention of fluid leakage under various operating conditions.

[0028] In practical applications, rotating the wheel 21 drives the screw 22 to move up and down, which in turn causes the gate 23 to slide up and down within the gate slot 121, thus controlling the opening and closing of the channel 12. Due to the threaded connection, there is a proportional relationship between the rotation angle of the wheel 21 and the moving distance of the gate 23, enabling relatively precise flow control. Simultaneously, the design of the gate guide port 131 makes the gate 23 more stable during movement, reducing the problem of decreased control accuracy caused by insensitive operation or equipment aging.

[0029] This utility model's easily adjustable gate valve achieves precise control over its opening and closing through the cooperation of a rotary wheel and a screw. At the same time, the design of the gate guide port improves the stability and sealing performance of the gate valve, meeting the application requirements of high-demand applications.
