Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a novel gate valve with adjustable flow rate. Background Technology

[0002] A gate valve is an opening and closing element consisting of a gate. The direction of movement of the gate is perpendicular to the direction of fluid flow. The gate valve seals by contact between the valve seat and the gate. Usually, the sealing surface is overlaid with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc.

[0003] Currently, gate valves typically use a gate to isolate the pipeline. During use, the flow rate of the gate valve is usually adjusted by regulating the opening degree of the gate. However, when the opening degree of the gate is relatively small, the impact force of the water flow will be relatively large, which will damage the internal parts of the gate valve. At the same time, the pressure on the gate will also increase. Prolonged use will damage the gate, thereby reducing the service life of the gate valve. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel gate valve with adjustable flow rate, which solves the problem of increased water flow impact force when adjusting water flow in traditional gate valves. It avoids damage to internal components and gate plates caused by water flow impact force, and at the same time extends the service life of the gate valve.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel gate valve with adjustable flow rate, comprising a valve body, a limiting ring provided inside one end of the valve body, the outer surface of the limiting ring being fixedly connected to the inner wall of the valve body, a movable cup slidably provided inside the limiting ring, and a through hole opened on one side surface of the movable cup, the through hole being located on one side of the limiting ring, a hinge seat slidably connected to one end of the movable cup, and a hinge plate hinged inside the hinge seat, a drive shaft fixedly connected to one side surface of the hinge plate, and an adjusting mechanism connected to one end of the drive shaft passing through the valve body, and an outer valve plate rotatably connected to the other end inside the valve body, and an inner hole opened inside the outer valve plate, an inner valve plate rotatably connected inside the inner hole.

[0006] Preferably, an adjusting box is fixedly connected to one side surface of the valve body, and a drive box is fixedly connected to one side surface of the adjusting box. A worm gear II is rotatably connected inside the drive box, and one side surface of the worm gear II is fixedly connected to one end of the drive shaft. A worm II is meshed with the side surface of the worm gear II, and a rotating disk is fixedly connected to the upper end of the worm II through the adjusting box. The worm II is rotatably connected to the inner wall of the drive box.

[0007] Preferably, a rotating shaft I is fixedly connected to the side surface of the outer valve plate, and the upper end of the rotating shaft I passes through the valve body and is connected to a limit mechanism. A worm gear I is fixedly connected to the upper side surface of the rotating shaft I, and a worm I is meshed with the side surface of the worm gear I. A support plate is fixedly connected to the side surface of the worm I.

[0008] Preferably, a rotating shaft II is rotatably connected inside the rotating shaft I, and an adjusting disc is fixedly connected to the upper end of the rotating shaft II. A limit rod is fixedly connected to the lower surface of the adjusting disc, and the lower end of the rotating shaft II passes through the outer valve plate and is fixedly connected to the side surface of the inner valve plate.

[0009] Preferably, the limiting mechanism includes a limiting plate, and the limiting plate is fixedly connected to the upper end of the rotating shaft I. The upper surface of the limiting plate has multiple sets of limiting holes, and the limiting holes correspond to the limiting rods.

[0010] Preferably, sealing rings are fixedly installed on the side surface of the outer valve plate, the side surface of the inner valve plate, and the inner surface of the limiting ring.

[0011] This invention provides a novel gate valve with adjustable flow rate. Compared with the prior art, it has the following advantages:

[0012] The gate valve's flow rate is easily adjusted by the interaction between the inner hole inside the outer valve plate, the inner valve plate which is rotatably connected to the inner hole, the movable cup inside the limiting ring which is fixedly connected to the inner wall of the valve body, and the through hole on one side surface of the movable cup. After adjusting the flow rate, the movable cup can further block the water flow, thus reducing the impact force of the water flow on the outer and inner valve plates and preventing damage to the internal components of the valve body, as well as the outer and inner valve plates, thereby extending the service life of the gate valve.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a novel gate valve with adjustable flow rate, including a valve body 1. A limiting ring 3 is provided inside one end of the valve body 1, and the outer surface of the limiting ring 3 is fixedly connected to the inner wall of the valve body 1. A movable cup 301 is slidably provided inside the limiting ring 3, and a through hole 302 is opened on one side surface of the movable cup 301. The through hole 302 is located on one side of the limiting ring 3. A hinge seat 303 is slidably connected to one end of the movable cup 301, and a hinge plate 304 is hinged inside the hinge seat 303. A drive shaft 305 is fixedly connected to one side surface of the hinge plate 304, and one end of the drive shaft 305 passes through the valve body 1 and is connected to an adjustment mechanism. The other end inside the valve body 1 is rotatably connected to an outer valve plate 409, and an inner valve plate 401 is rotatably connected inside the inner hole 409.

[0021] As a technical optimization of this utility model, a regulating box 2 is fixedly connected to one side surface of the valve body 1, and a drive box 201 is fixedly connected to one side surface of the regulating box 2. A worm gear II 203 is rotatably connected inside the drive box 201, and one side surface of the worm gear II 203 is fixedly connected to one end of the drive shaft 305. A worm II 204 is meshed with the side surface of the worm gear II 203, and a rotating disk 202 is fixedly connected to the upper end of the worm II 204 through the regulating box 2. The worm II 204 is rotatably connected to the inner wall of the drive box 201. The drive shaft 305 is easily driven to rotate through the worm II 204 and the worm gear II 203. The through hole 302 slides inside the limiting ring 3 through the drive shaft 305 and the hinge plate 304, thereby adjusting the flow rate of the gate valve.

[0022] As a technical optimization of this utility model, a rotating shaft I403 is fixedly connected to the side surface of the outer valve plate 4, and the upper end of the rotating shaft I403 passes through the valve body 1 and is connected to a limit mechanism. A worm gear I103 is fixedly connected to the upper side surface of the rotating shaft I403, and a worm I102 is meshed with the side surface of the worm gear I103. A support plate 101 is fixedly connected to the side surface of the worm I102, which can drive the outer valve plate 4 to rotate, thereby adjusting the opening degree of the outer valve plate 4.

[0023] As a technical optimization of this utility model, a rotating shaft II 4010 is rotatably connected inside the rotating shaft I 403, and an adjusting plate 406 is fixedly connected to the upper end of the rotating shaft II 4010. A limit rod 407 is fixedly connected to the lower surface of the adjusting plate 406, and the lower end of the rotating shaft II 4010 passes through the outer valve plate 4 and is fixedly connected to the side surface of the inner valve plate 401. The inner valve plate 401 and the adjusting plate 406 facilitate the operator to drive the inner valve plate 401 to rotate, and can further adjust the flow of the gate valve.

[0024] As a technical optimization of this utility model, the limiting mechanism includes a limiting disk 405, and the limiting disk 405 is fixedly connected to the upper end of the rotating shaft I 403. The upper surface of the limiting disk 405 is provided with multiple sets of limiting holes 408, and the limiting holes 408 correspond to the limiting rod 407, which can limit the rotating shaft II 4010 and the inner valve plate 401, and prevent the impact force of the water flow from causing the inner valve plate 401 to rotate.

[0025] As a technical optimization of this utility model, sealing rings 402 are fixedly installed on the side surface of the outer valve plate 4, the side surface of the inner valve plate 401, and the inner surface of the limiting ring 3.

[0026] In use, the operator first rotates the worm gear II 204 via the rotating disk 202. This worm gear II 204 drives the worm wheel II 203 inside the drive box 201 to rotate. The rotating worm wheel II 203 then drives the drive shaft 305 to rotate. Therefore, the drive shaft 305, through the hinge plate 304 and hinge seat 303, pulls the movable cup 301 to slide inside the limiting ring 3, causing a portion of the through hole 302 at one end of the movable cup 301 to move to one side of the limiting ring 3. Then, the operator rotates the worm gear I 102. This worm gear I 102, through the worm wheel I 103, drives the outer valve plate 4 inside the other end of the valve body 1 to rotate. At this time, the inner valve plate 401 inside the inner hole 409 rotates along with the outer valve plate 4, causing the valve body 1 to rotate. The valve will be opened, and the water will then flow through the outer valve plate 4 and impact the other end of the moving cup 301. At the same time, it will flow through the through hole 302 on the side surface of the moving cup 301 to one end of the valve body 1. When it is necessary to increase the flow rate, the operator can move all the through holes 302 at one end of the moving cup 301 to one side of the limiting ring 3. At this time, the flow rate will increase, and vice versa. If it is necessary to reduce the flow rate again, the operator first closes the outer valve plate 4, then pulls the adjusting plate 406 upward so that the limiting rod 407 on the lower surface of the adjusting plate 406 disengages from the limiting hole 408. Then, the adjusting plate 406 and the rotating shaft II 4010 are rotated, so that the rotating shaft II 4010 will open the inner valve plate 401. At this time, the outer valve plate 4 can further reduce the water flow rate.
