Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically to a flanged rising stem gate valve. Background Technology

[0002] Flanged gate valves are gate valves with flanges as the connection method. This connection method is the most common. Flanged gate valves are stable and reliable when used in pipelines, so they are often used in high-pressure pipelines. According to the configuration of the sealing surface, they can be divided into wedge gate valves and parallel gate valves. Wedge gate valves can be further divided into single gate, double gate, and resilient gate types. Parallel gate valves can be divided into single gate and double gate types. According to the position of the valve stem thread, they can be divided into rising stem gate valves and non-rising stem gate valves.

[0003] In the use of gate valves, due to the limitations of the gate shape, the gate can only be fully opened or fully closed during its movement, and cannot be adjusted or throttled. As a result, the gate valve cannot accurately control the flow rate of the liquid during use. To address this, a flanged rising stem gate valve is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the gate valve can only be fully opened or fully closed during the movement of the gate, and cannot be adjusted or throttled, which makes it impossible to accurately control the flow rate of the liquid during the use of the gate valve. This utility model provides a flanged rising stem gate valve.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A flanged rising stem gate valve, comprising:

[0007] A fixed shell, wherein the fixed shell is open on one side, the opening end of the fixed shell is provided with a mounting cover, and the outside of the fixed shell is provided with multiple connecting pipes, which are connected to the fixed shell.

[0008] A control mechanism, located inside the fixed housing, is used to control the flow of water. The control mechanism includes a seal and an adjusting component. The seal is located inside the fixed housing and is used to control the water flow. The adjusting component is located inside the fixed housing and is used to adjust the position of the seal. The adjusting component works with the seal to adjust the water flow rate.

[0009] Furthermore, the adjusting component includes a threaded rod connected to the mounting cover, with the axis of the threaded rod parallel to the opening direction of the fixed shell. One end of the threaded rod is provided with a connecting rod and a sliding plate in sequence.

[0010] Furthermore, the sealing element includes a gate plate that slides inside the fixed housing. The sliding direction of the gate plate is parallel to the axis of the connecting rod. A sliding groove is provided inside the gate plate, and a sliding plate slides inside the sliding groove. A through hole is provided on the outside of the gate plate, which penetrates the gate plate and is connected to the sliding groove. The opening direction of the through hole is parallel to the opening direction of the connecting pipe.

[0011] Furthermore, a guide groove is provided inside the sliding groove, and a guide block is slidably connected inside the guide groove, and the guide block is connected to the sliding plate.

[0012] Furthermore, the gate is provided with a spring and a connecting plate in sequence on the side opposite to the mounting cover, and the connecting plate is connected to the mounting cover.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model, through the setting of adjusting components and sealing components, realizes the coordination of sliding plate, threaded rod, connecting rod, gate plate, sliding groove and through hole, so that the water flow rate can be adjusted during use. This avoids the situation where the gate plate can only be fully open or fully closed during the movement of the gate valve, which would prevent the gate valve from accurately controlling the liquid flow rate during use.

[0025] like Figures 1 to 4 As shown, a flanged rising stem gate valve includes: a fixed shell 1, which is open on one side, with a mounting cover 101 at the open end; multiple connecting pipes 102 are provided on the outside of the fixed shell 1, and the connecting pipes 102 are connected to the fixed shell 1; and a control mechanism, disposed inside the fixed shell 1, for controlling the flow of water. The control mechanism includes a sealing element 3 and an adjusting element 2. The sealing element 3 is disposed inside the fixed shell 1 for controlling the water flow, and the adjusting element 2 is disposed inside the fixed shell 1 for adjusting the position of the sealing element 3. The adjusting element 2 works with the sealing element 3 to adjust the water flow rate. Specifically, when it is necessary to adjust the water flow... During control, the water flow inside the connecting pipe 102 is first controlled by the cooperation of the adjusting component 2 and the sealing component 3, so that the water flow can be controlled according to the actual use requirements. At the same time, the water flow rate through the sealing component 3 is adjusted by the movement of the adjusting component 2 relative to the sealing component 3, so that the water can meet the use requirements. The fixed shell 1 and the mounting cover 101 can be connected by a bolt or clamp, which facilitates the maintenance and replacement of the adjusting component 2 and the sealing component 3 during use. During use, the connecting pipe 102 is connected to the water pipe through a flange to ensure that the water can flow stably inside the fixed shell 1.

[0026] like Figures 1 to 4 As shown, the adjusting component 2 includes a threaded rod 202, which is connected to the mounting cover 101. The axis of the threaded rod 202 is parallel to the opening direction of the fixed shell 1. One end of the threaded rod 202 is provided with a connecting rod 203 and a sliding plate 201 in sequence. Specifically, a control disc is also provided on the outside of the threaded rod 202. The control disc is rotatably connected to the mounting cover 101. The control disc and the threaded rod 202 are connected by threads. In use, the rotation of the control disc drives the threaded rod 202 and the connecting rod 203 to move linearly relative to the mounting cover 101. While the connecting rod 203 moves with the threaded rod 202, it drives the sliding plate 201 to move relative to the sealing component 3, thereby realizing the control of water flow. There are no restrictions on the shape of the connecting rod 203. It can be cylindrical, hexagonal prism, or elliptical prism, etc.

[0027] like Figures 1 to 4 As shown, the sealing element 3 includes a gate plate 301, which slides inside the fixed housing 1. The sliding direction of the gate plate 301 is parallel to the axis of the connecting rod 203. A sliding groove 302 is provided inside the gate plate 301, and the sliding plate 201 slides inside the sliding groove 302. A through hole 306 is provided on the outer side of the gate plate 301, which penetrates the gate plate 301 and communicates with the sliding groove 302. The opening direction of the through hole 306 is parallel to the opening direction of the connecting pipe 102. Specifically, during the process of controlling the water flow, the gate plate 301 moves relative to the fixed housing 1 through the cooperation of the connecting rod 203 and the threaded rod 202, thereby controlling the flow of water. During the movement of the gate plate 301, the fixed housing 1 provides guidance for the moving gate plate 301. To ensure stable water flow control, the gate 301 first cuts off the water flow inside the connecting pipe 102 by cooperating with the threaded rod 202 and the connecting rod 203. Then, the sliding plate 201 moves along the sliding groove 302 by cooperating with the threaded rod 202 and the connecting rod 203. By adjusting the overlap range between the sliding plate 201 and the through hole 306, the water flow inside the through hole 306 can be controlled. The size of the through hole 306 can be adjusted according to actual usage requirements, and the shape of the through hole 306 can be a directional hole, a circular hole, or a hexagonal hole. During use, the sliding plate 201, in conjunction with the sliding groove 302, can seal the through hole 306 to prevent water leakage during the cutoff process.

[0028] like Figures 1 to 4As shown, a guide groove 305 is provided inside the sliding groove 302, and a guide block is slidably connected inside the guide groove 305. The guide block is connected to the sliding plate 201. Specifically, during the movement of the sliding plate 201 relative to the gate 301, the movement direction of the sliding plate 201 is guided by the cooperation of the guide groove 305 and the guide block, so as to ensure that the sliding plate 201 can move stably relative to the gate 301.

[0029] like Figures 1 to 4 As shown, the gate 301 is provided with a spring 303 and a connecting plate 304 on the side opposite to the mounting cover 101, and the connecting plate 304 is connected to the mounting cover 101. Specifically, during the position adjustment of the sliding plate 201, the connecting plate 304 and the spring 303 provide support for the gate 301, so that the position of the gate 301 relative to the fixed shell 1 is stable during the movement of the sliding plate 201, and the water flow can be stably controlled. The connecting plate 304 and the mounting cover 101 can be connected by bolts or buckles. When the sliding plate 201 moves to the top of the sliding groove 302, the threaded rod 202 and the connecting rod 203 cooperate with the sliding plate 201 to drive the gate 301 to move relative to the fixed shell 1. At the same time as the gate 301 moves, the water flow inside the connecting pipe 102 is controlled.
