Description

Technical Field

[0001] This utility model relates to the field of valve body sealing technology, and in particular to a valve body sealing structure. 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. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications.

[0003] When the existing valve body, which uses threaded connections, is connected to the pipeline at both ends, a certain force is generated during the fluid transportation process. After long-term operation, the pipeline is prone to stripping, which may lead to leakage at the connection between the valve body and the pipeline after long-term use, affecting the sealing effect of the valve body.

[0004] Therefore, it is necessary to provide a new valve body sealing structure to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the valve body sealing structure provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the first electric telescopic rod and the lower clamping seat. Figure 3 for Figure 1 The diagram shows the structure of the valve body and valve core. The valve body sealing structure includes a first receiving box 1, a fixed seat 2 fixedly connected to the top of the first receiving box 1, a valve body 3 fixedly connected to the top of the fixed seat 2, and internal threaded cylinders 4 provided at both ends of the valve body 3.

[0022] The upper part of both ends of the top of the first receiving box 1 is provided with a lower clamping seat 10 that moves in the vertical direction. Both ends of the top of the first receiving box 1 are vertically fixedly connected to a support rod 11. The top of the support rod 11 is fixedly connected to a second receiving box 12. The lower part of the second receiving box 12 is provided with an upper clamping seat 14 that moves in the vertical direction.

[0023] The upper clamping seat 14 and the lower clamping seat 10 at the same end form a clamping part for fixing the pipeline. Both the upper clamping seat 14 and the lower clamping seat 10 are provided with sealing gaskets on the side near the valve body 3.

[0024] After the pipe is threadedly connected to the internal threaded cylinder 4, the lower clamping seat 10 and the upper clamping seat 14 can move closer to each other to clamp and fix the pipe after the threaded connection, thereby reducing the impact on the pipe during fluid transportation and improving the stability of the pipe after the threaded connection with the internal threaded cylinder 4.

[0025] During clamping, the sealing gasket abuts against the outside of the connection between the pipe and the internal threaded cylinder 4, which can effectively prevent leakage and improve the stability of the valve body 3 during use, thus facilitating fluid transportation.

[0026] Both ends of the inner cavity of the first receiving box 1 are vertically fixedly connected to the first electric telescopic rod 9. The top end of the first electric telescopic rod 9 is pulled out to the outside of the first receiving box 1 and is fixedly connected to the bottom of the lower clamping seat 10 at the same end.

[0027] The inner cavity of the second receiving box 12 is vertically fixedly connected to a second electric telescopic rod 13. The bottom end of the second electric telescopic rod 13 extends movably to the outside of the second receiving box 12 and is fixedly connected to the top of the clamping seat 14 at the same end.

[0028] During the extension and retraction of the first electric telescopic rod 9 and the second electric telescopic rod 13, the distance between the lower clamping seat 10 and the upper clamping seat 14 can be adjusted.

[0029] The lower clamping seat 10 is fixedly connected to the top of the lower positioning post 15, and the bottom of the upper clamping seat 14 is provided with an upper positioning groove 16 that is adapted to the lower positioning post 15.

[0030] When the lower clamping seat 10 and the upper clamping seat 14 approach each other, the lower positioning post 15 is driven to embed into the interior of the upper positioning groove 16, thereby positioning the lower clamping seat 10 and the upper clamping seat 14.

[0031] The side walls of the first container 1 and the second container 12 are both equipped with inspection covers 22 by means of several screws 21. Several mounting blocks 20 are fixedly connected to the bottom of the side wall of the first container 1.

[0032] The inner cavity of the first receiving box 1 is provided with a valve disc 7, and the top of the inner cavity of the valve body 3 is provided with a valve stem 5. The top of the valve stem 5 is fixedly connected with a torsion handle 8, and the top of the torsion handle 8 extends to the outside of the first receiving box 1.

[0033] A support plate 17 is fixedly connected to the side wall of the valve body 3. A third electric telescopic rod 18 is fixedly connected to the upper surface of the support plate 17. A contact block 19 that can abut against the surface of the torsion handle 8 is fixedly connected to the top of the third electric telescopic rod 18.

[0034] After the third electric telescopic rod 18 extends, it can contact the surface of the torsion handle 8 through the contact block 19 to fix the torsion handle 8, so as to prevent the valve core 6 from shifting due to the influence of external force on the torsion handle 8, and thus improve the stability of the valve body 3 after opening and closing.

[0035] The working principle of the valve body sealing structure provided by this utility model is as follows:

[0036] After the pipe is threadedly connected to the internally threaded cylinder 4, the distance between the lower clamping seat 10 and the upper clamping seat 14 can be adjusted during the extension and retraction of the first electric telescopic rod 9 and the second electric telescopic rod 13. By moving the lower clamping seat 10 and the upper clamping seat 14 closer to each other, the threaded pipe is clamped and fixed, reducing the impact on the pipe during fluid transportation and improving the stability of the pipe after the threaded connection with the internally threaded cylinder 4. During the clamping process, the sealing gasket abuts against the outside of the connection between the pipe and the internally threaded cylinder 4, which can effectively prevent leakage.

[0037] Compared with related technologies, the valve body sealing structure provided by this utility model has the following beneficial effects:

[0038] This utility model provides a valve body sealing structure. After the pipe is threadedly connected to the internal threaded cylinder 4, the lower clamping seat 10 and the upper clamping seat 14 can move closer to each other to clamp and fix the threaded pipe, reducing the impact on the pipe during fluid transportation and improving the stability of the pipe and internal threaded cylinder 4 after threaded connection. During the clamping process, the sealing gasket abuts against the outside of the connection between the pipe and the internal threaded cylinder 4, which can effectively prevent leakage and improve the stability of the valve body 3 during use, which is beneficial for fluid transportation. After the third electric telescopic rod 18 is extended, it can abut against the surface of the torsion handle 8 through the abutment block 19 to fix the torsion handle 8, avoiding the valve core 6 from being offset by external force, and improving the stability of the valve body 3 after opening and closing.
