Description
Technical Field
[0001] This utility model belongs to the technical field of valve installation components, and in particular relates to a valve connector. Background Technology
[0002] Valve pipe fittings are key components used to connect valves to piping systems. They ensure the continuity and controllability of fluid transmission. When adding a valve to an existing pipeline, if there is a diameter difference between the valve's two ends and the pipeline, or if they cannot be matched for installation, valve fittings are needed. However, general valve fittings are only available in specific models and cannot be matched to the same type of valve for a certain range of pipe diameters. Using flexible hoses for connection is not very stable.
[0003] To address these issues, we provide a valve connector. Utility Model Content
[0004] The purpose of this utility model is to provide a valve connector that adapts to and fixes pipes within a certain diameter range using pipe fixing components, and connects pipes and valves using valve connection assemblies, thus solving the problem that existing valves and pipes cannot be connected using valve connectors when they are not compatible.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a valve connector, comprising a pipe fixing component and a valve connection assembly. The pipe fixing component includes a pipe sleeve and a clamping assembly disposed on the pipe sleeve. The valve connection assembly includes a conical rubber sleeve, a first sleeve, a second sleeve, and a flange sleeve. The left end of the first sleeve is screwed onto the right end of the pipe sleeve. The left end of the second sleeve is screwed onto the right end of the first sleeve. The left end of the flange sleeve is screwed onto the right end of the second sleeve. A flange is disposed on the right end of the flange sleeve. Both ends of the conical rubber sleeve are provided with extended annular rubber gaskets. The annular rubber gasket at the left end of the conical rubber sleeve is pressed against the left end of the first sleeve, and the annular rubber gasket at the right end is pressed against the right end of the second sleeve.
[0007] The present invention is further configured such that the pipe sleeve has a square hole around its perimeter, the square hole has a spring notch on the rear side wall of the inner side of the pipe sleeve, the square hole has symmetrical shaft notches on the two side walls of the outer side of the pipe sleeve near the rear side wall, the pipe sleeve has an external thread, and a threaded connector is connected to the right end of the pipe sleeve.
[0008] The clamping assembly includes an adjusting collar and a pressing block. The adjusting collar is screwed onto an external thread. The pressing block has a spring plate at its bottom rear end, and a return spring is fixed on the spring plate. The pressing block has symmetrical shafts on its two side walls near the bottom rear end. The return spring is engaged in a spring notch, and the two shafts are engaged in corresponding shaft notches. The pressing block is located in a square hole.
[0009] The present invention is further configured such that the bottom of the extrusion block is a horizontal plane, the top is an upwardly inclined slope, and the corner of the bottom of the extrusion block away from the spring plate is an arc corner.
[0010] The present invention is further configured such that a first extrusion platform is provided inside the left side end of the first sleeve, and the annular rubber pad at the left side end of the conical rubber sleeve is attached to the first extrusion platform. When the threaded joint is screwed into the left side end of the first sleeve, the annular rubber pad is extruded.
[0011] The present invention is further configured such that a second extrusion platform is provided inside the right side end of the second sleeve, the annular rubber gasket of the right side end of the conical rubber sleeve is attached to the second extrusion platform, and the annular rubber gasket is extruded when the left side end of the flange sleeve is screwed into the right side end of the second sleeve.

Detailed Implementation
[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-7This utility model relates to a valve connector, comprising a pipe fixing component and a valve connection assembly. The pipe fixing component includes a pipe sleeve 1 and a clamping assembly disposed on the pipe sleeve 1. The valve connection assembly includes a conical rubber sleeve 7, a first sleeve 4, a second sleeve 5, and a flange sleeve 6. The left end of the first sleeve 4 is screwed onto the right end of the pipe sleeve 1. The left end of the second sleeve 5 is screwed onto the right end of the first sleeve 4. The left end of the flange sleeve 6 is screwed onto the right end of the second sleeve 5. A flange 61 is disposed on the right end of the flange sleeve 6. Both ends of the conical rubber sleeve 7 are provided with an extended annular rubber gasket 71. The annular rubber gasket 71 at the left end of the conical rubber sleeve 7 is pressed against the left end of the first sleeve 4, and the annular rubber gasket 71 at the right end of the conical rubber sleeve 7 is pressed into the right end of the second sleeve 5.
[0029] In some pipelines, during later modifications, it may be necessary to find a matching valve for a specific pipeline, even though the valve fittings are designed for matching valves. When a matching valve cannot be found for a pipeline diameter, a valve fitting suitable for a certain range of pipe diameters is required for valve installation. This application involves passing the pipeline through the pipe sleeve 1, fitting the left side of the conical rubber sleeve 7 onto the pipeline until a section is fitted, and then securing it to the outside of the conical rubber sleeve 7 with wire or fastening strips to achieve a tight seal. The left end of the first sleeve 4 is then fitted onto the right end of the conical rubber sleeve 7 until its left end is positioned to the left of the conical rubber sleeve 7. The pipe sleeve 1 is then connected to the left end of the first sleeve 4, pressing against the conical rubber sleeve 7 to achieve a seal. Finally, a clamping assembly is used to clamp the pipeline. Next, insert the second sleeve 5 onto the conical rubber sleeve 7 and connect it to the first sleeve 4. Use a pull rod to pull the right end of the conical rubber sleeve 7 to the right so that it fits into the right end of the second sleeve 5. Then, screw the left end of the flange sleeve 6 into the right end of the second sleeve 5 to compress the conical rubber sleeve 7, thus completing the installation of the connector. The flange can then be connected to the matching valve.
[0030] The pipe sleeve 1 is provided with a square hole 13 around the perimeter. The square hole 13 has a spring notch 131 on the rear side wall of the inner side of the pipe sleeve 1. The square hole 13 has symmetrical shaft notches 132 on the two side walls of the outer side of the pipe sleeve 1 near the rear side wall. The pipe sleeve 1 is provided with an external thread 11. The right end of the pipe sleeve 1 is connected to a threaded connector 12.
[0031] The clamping assembly includes an adjusting collar 3 and a pressing block 2. The adjusting collar 3 is screwed onto the external thread 11. The pressing block 2 has a spring plate 21 at the rear end of the bottom. A return spring 23 is fixed on the spring plate 21. The pressing block 2 has symmetrical shafts 22 on both sides of the rear end near the bottom. The return spring 23 is locked in the spring notch 131. The two shafts 22 are locked in the shaft notches 132 respectively. The pressing block 2 is located in the square hole 13.
[0032] When the pipe is inserted into the pipe sleeve 1, since the inner diameter of the pipe sleeve 1 is larger than the outer diameter of the pipe to be connected, the inward movement of the pressing block 2 can be adjusted. When the adjusting collar 3 is rotated to the left, the pressing block 2 is simultaneously pressed downward, pressing it onto the pipe and fixing it in place, thus centering the pipe. The return spring prevents the pressing block 2 from falling when it is not being pressed; it can only move downward when pressed.
[0033] The bottom of the extrusion block 2 is horizontal, and the top is an upwardly sloping surface. The corner at the bottom of the extrusion block 2 away from the spring plate 21 is an arc-shaped corner. The arc-shaped corner facilitates the extrusion contact with the pipe. The upwardly sloping surface facilitates the downward movement of the extrusion block 2 during pushing.
[0034] The first sleeve 4 has a first extrusion platform 41 inside the left side end. The annular rubber pad 71 at the left side end of the conical rubber sleeve 7 is attached to the first extrusion platform 41. When the threaded joint 12 is screwed into the left side end of the first sleeve 4, it extrudes the annular rubber pad 71.
[0035] The threaded connector 12 is pressed between the end of the threaded connector 12 and the first pressing table 41 to form an annular rubber gasket 71, thereby achieving a seal.
[0036] The second sleeve 5 is provided with a second extrusion table 51 inside the right end. The annular rubber gasket 71 of the right end of the conical rubber sleeve 7 is attached to the second extrusion table 51. When the left end of the flange sleeve 6 is screwed into the right end of the second sleeve 5, the annular rubber gasket 71 is extruded.
[0037] Similarly, sealing is achieved by squeezing the annular rubber gasket 71.
[0038] Insert the pipe end connected to the valve through the left side of the conical sleeve 7 until a section of the conical sleeve 7 is tightly fitted onto the pipe end. Then, secure it to the outside of the conical sleeve 7 with a steel wire or fastening strip. At a certain section, the conical sleeve 7 can be opened to a certain extent before being secured with a steel wire or fastening strip, achieving a seal and thus completing the pipe connection.
