Description

Technical Field

The outer surface of the sealing plate is arc-shaped corresponding to the inner wall of the mounting cylinder. A rotating component is provided on one side of the mounting cylinder for rotating the connecting plate to drive the sealing plates to rotate, thereby gradually closing the flow holes.

[0009] As a preferred technical solution, the rotating component includes a housing fixedly installed at one end of the mounting cylinder. A mounting rod is rotatably and sealed in the middle of the housing. One end of the mounting rod penetrates the surface of the mounting cylinder. The other end of the mounting rod located inside the mounting cylinder is fixedly connected to the surface of the connecting disc. A worm gear is fixedly sleeved on the surface of the mounting rod located inside the housing. A worm is meshed on the surface of the worm gear. A bearing seat is fixedly installed on the inner wall of the bottom of one end of the housing. One end of the worm is fixedly inserted into the inner ring of the bearing in the bearing seat. The other end of the worm is fixedly connected to a connecting rod. One end of the connecting rod passes through the housing and the valve body in sequence and extends to the outside of the valve body. A handwheel is fixedly connected to the end of the connecting rod located on the outside of the valve body.

[0010] As a preferred technical solution, a connecting seat is fixedly connected to the surface of the valve body at a position corresponding to the outer circular surface of the connecting rod. One end of the connecting rod rotatably passes through the connecting seat.

[0013] As a preferred technical solution, the connecting component includes flanges that are respectively fixedly installed at the inlet and outlet ends of the valve body.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a sealing element to control the opening and closing of the flow hole by rotating the connecting disc and driving the sealing plate to rotate. It can evenly distribute the external driving force to the upper and lower sealing plates, ensuring that the two sealing plates move synchronously, thereby accurately controlling the opening and closing degree of the flow hole. At the same time, when the sealing plate opens or closes, the contact between the edge of the sealing plate and the area around the flow hole scrapes off some small particles of impurities or scale, allowing them to be washed away with the water flow, thus preventing blockage of the flow hole. Furthermore, the outer surface of the sealing plate is arc-shaped, corresponding to the inner wall of the mounting cylinder, which can increase the contact area between the sealing plate and the inner wall of the mounting cylinder, improve the sealing performance, and effectively prevent water leakage from the gap between the sealing plate and the mounting cylinder under certain water pressure.

[0016] 2. This utility model, through the setting of a rotating component, allows the handwheel to rotate the connecting rod, which in turn drives the worm gear to rotate. The worm gear, in turn, drives the connecting plate to rotate via a mounting rod fixedly connected to the middle of the worm gear. This precisely converts the rotational motion of the handwheel into the rotation of the connecting plate, enabling more precise adjustment of the sealing plate's opening. Furthermore, due to the self-locking characteristic between the worm gear and the worm, the valve can be stably maintained in the set position after the flow rate is adjusted, without changing the opening due to factors such as water pressure fluctuations, thus improving the accuracy and stability of flow control.

[0017] 3. By setting up a pointer and scale lines, the scale lines on the surface of the connecting seat cooperate with the pointer on the connecting rod. Operators do not need to use additional measuring tools. They can quickly and accurately understand the opening degree of the valve and the corresponding water flow rate simply by observing the position of the pointer on the scale lines. At the same time, the limiting pieces on the surface of the connecting seat at the beginning and end of the scale lines can prevent the connecting rod from rotating excessively.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-4 This embodiment provides an adjustable flow building water supply and drainage valve structure, including a valve body 101. An installation cylinder 103 is fixedly connected to the water inlet port of the valve body 101. Flow holes 104 for water flow are opened on the inner walls of the left and right sides of the installation cylinder 103. A sealing component for sealing the flow holes 104 is provided inside the installation cylinder 103. Both the water inlet and outlet ends of the valve body 101 are provided with connectors for connecting pipes.

[0028] The sealing assembly includes a connecting disc 110 rotatably connected to the inner wall of the bottom of the mounting cylinder 103. Sealing plates 105 for sealing the flow holes 104 are fixedly connected to both the upper and lower ends of the front side of the connecting disc 110. The outer surface of the sealing plates 105 is arc-shaped corresponding to the inner wall of the mounting cylinder 103. A rotating component is provided on one side of the mounting cylinder 103 for rotating the connecting disc 110, thereby driving the sealing plates 105 to rotate and gradually closing the flow holes 104. Through the sealing component, the rotation of the connecting disc 110 drives the rotation of the sealing plates 105 to control the opening and closing of the flow holes 104, and can evenly distribute the external driving force to the upper and lower sealing plates 105. On 05, the two sealing plates 105 move synchronously, thereby precisely controlling the opening and closing degree of the flow hole 104. At the same time, when the sealing plate 105 opens or closes, the contact between the edge of the sealing plate 105 and the area around the flow hole 104 scrapes off some small particles of impurities or scale, allowing them to be washed away with the water flow, thus preventing blockage of the flow hole 104. Furthermore, the outer surface of the sealing plate 105 is set in a corresponding arc shape with the inner wall of the mounting cylinder 103, which can increase the contact area between the sealing plate 105 and the inner wall of the mounting cylinder 103, improve the sealing performance, and effectively prevent water from leaking from the gap between the sealing plate 105 and the mounting cylinder 103 under a certain water pressure.

[0029] The rotating component includes a housing 106 fixedly mounted to one end of the mounting cylinder 103. A mounting rod 305 is rotatably connected to the middle of the housing 106. One end of the mounting rod 305 penetrates the surface of the mounting cylinder 103. The other end of the mounting rod 305, located inside the mounting cylinder 103, is fixedly connected to the surface of the connecting disc 110. A worm gear 304 is fixedly sleeved on the surface of the mounting rod 305 inside the housing 106. A worm 302 meshes with the surface of the worm gear 304. A bearing seat 303 is fixedly mounted on the inner wall of the bottom of one end of the housing 106. One end of the worm 302 is fixedly inserted into the inner ring of the bearing in the bearing seat 303. The other end of the worm 302 is fixedly connected to a connecting rod 301. One end of the connecting rod 301 passes through the housing 106 and the valve body 101 sequentially. Furthermore, extending to the outside of the valve body 101, a handwheel 300 is fixedly connected to the end of the connecting rod 301 located on the outside of the valve body 101. Through the setting of the rotating component, the handwheel 300 rotates the connecting rod 301, which drives the worm wheel 304 to rotate via the worm gear 302. The worm wheel 304 is then driven to rotate via the mounting rod 305 fixedly connected to the middle of the worm wheel 304. This precisely converts the rotational motion of the handwheel 300 into the rotation of the connecting plate 110, allowing for more precise adjustment of the opening of the sealing plate 105. Moreover, due to the self-locking characteristic between the worm wheel 304 and the worm gear 302, it can be ensured that after the flow rate is adjusted, the valve can be stably maintained in the set position, and the opening will not change due to factors such as water pressure fluctuations, thus improving the accuracy and stability of flow control.

[0030] The sealing and rotatable connection of the mounting rod 305 in the middle of the housing 106 is a well-known technical means for those skilled in the art, and will not be described in detail here.

[0031] A connecting seat 102 is fixedly connected to the surface of the valve body 101 at a position corresponding to the outer circular surface of the connecting rod 301. One end of the connecting rod 301 rotatably passes through the connecting seat 102. A scale line 201 is provided on the surface of the connecting seat 102 corresponding to the outer circular surface of the connecting rod 301. A pointer 200 is provided on the surface of the connecting rod 301 to point to the scale line 201. Limiting pieces 202 are fixedly connected to the surface of the connecting seat 102 at positions corresponding to the start and end of the scale line 201. With the setting of the pointer 200 and the scale line 201, the scale line 201 on the surface of the connecting seat 102 cooperates with the pointer 200 on the connecting rod 301. The operator can quickly and accurately understand the valve opening and the corresponding water flow rate by simply observing the position of the pointer 200 on the scale line 201 without the need for additional measuring tools. At the same time, the limiting pieces 202 on the surface of the connecting seat 102 at the start and end of the scale line 201 can prevent the connecting rod 301 from rotating excessively.

[0032] Among them, a protective tube 107 is sleeved on the surface of the connecting rod 301 located between the valve body 101 and the housing 106. One end of the protective tube 107 is fixedly connected to the surface of the housing 106, and the other end of the protective tube 107 is fixedly connected to the inner wall of the valve body 101. Through the setting of the protective tube 107, the protective tube 107 is sleeved on the surface of the connecting rod 301 between the valve body 101 and the housing 106, which plays a role in physical protection. At the same time, the protective tube 107 can also prevent the surface of the connecting rod 301 from being corroded.

[0033] The inner wall of the mounting cylinder 103 is provided with an annular limiting groove 109 corresponding to the end of the sealing plate 105. Limiting strips 108 are slidably connected to the upper and lower inner walls of the annular limiting groove 109. The two sets of limiting strips 108 are respectively fixedly connected to the ends of the corresponding sealing plates 105. Through the setting of the limiting groove 109 and the limiting strips 108, the movement of the sealing plate 105 is precisely limited, ensuring the accurate alignment of the sealing plate 105 and the flow hole 104 and a good sealing effect. At the same time, during long-term use, it can effectively prevent the sealing plate 105 from shifting or misaligning due to water flow impact, vibration and other factors.

[0034] The connecting components include flanges 100 that are fixedly installed at the inlet and outlet ends of the valve body 101, which greatly improves the convenience and versatility of connecting the device to external pipelines.

[0035] The inner cavities of the two sets of flow holes 104 are connected to the interior of the valve body 101, and the opening of the mounting cylinder 103 is connected to the inner cavity of the flange 100 installed at the water inlet.

[0036] Working principle;

[0037] When it is necessary to open the valve to regulate the water flow, the operator turns the handwheel 300 located on the outside of the valve body 101. The rotation of the handwheel 300 drives the connecting rod 301 fixedly connected to it to rotate. As the connecting rod 301 rotates, it drives the worm gear 302 to rotate. Through the meshing of the worm gear 302 and the worm wheel 304, the worm wheel 304 is driven to rotate, which in turn drives the mounting rod 305 to rotate, thereby driving the connecting disc 110 located inside the mounting cylinder 103 to rotate.

[0038] As the connecting plate 110 rotates, the sealing plates 105 at its upper and lower ends also rotate, gradually moving away from the originally closed flow holes 104. Thus, water can enter from the flow holes 104 on the left and right sides of the mounting cylinder 103, flow through the inside of the valve body 101, and finally flow out from the outlet end of the valve body 101, thereby opening the valve. Furthermore, when the sealing plate 105 is open or in operation, the contact between the edge of the sealing plate 105 and the area around the flow holes 104 scrapes off some small particles of impurities or scale, allowing them to be washed away with the water flow, thereby preventing blockage of the flow holes 104.

[0039] Meanwhile, a scale line 201 is provided on the connecting seat 102 on the surface of the valve body 101, and a pointer 200 is provided on the connecting rod 301. By pointing the pointer 200 to the scale line 201, the operator can intuitively know the degree of valve opening, that is, the approximate current water flow. The limiting piece 202 on the connecting seat 102 limits the rotation range of the connecting rod 301 to avoid over-opening or over-closing, and ensure that the valve operation is within a reasonable range.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
