Description

Technical Field

[0001] The utility model relates to the field of valve installation, in particular to a connecting base suitable for a cylindrical valve of a wet alarm valve group. Background Art

[0002] When installing the wet alarm valve group, it is necessary to set up electrical circuits between the valve and the control box. Generally, only corrugated sleeves are used for protection of these electrical circuits. However, the corrugated sleeves are hoses and cannot provide rigid constraints on the routing of the circuits, resulting in random hanging and connection of wires, which poses a risk of short circuits and affects the appearance.

[0003] In the prior application of the applicant, a wet alarm valve control wire restraint scheme was proposed. For details, please refer to patents 202110833854.8, 202121680559.5, and 202121680521.8. In this scheme, hard PVC pipes are used to make restraint pipelines to restrain electrical circuits. At the same time, two connection bases connected to the valve and the control box are provided to achieve connection with the restraint pipeline.

[0004] However, the connection base with the valve in the above solution adopts a flat bottom structure, which is not suitable for connection and installation with a cylindrical valve.

[0005] Based on this, this case is brought forward. Utility Model Content

[0006] The utility model aims to provide a connection base suitable for a cylindrical valve of a wet alarm valve group, so as to realize a fixed connection between a restraining pipeline and the cylindrical valve of the wet alarm valve group.

[0007] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A connection base suitable for a cylindrical valve of a wet alarm valve group comprises a connection column, the lower part of which is provided with an integrally formed arc base, the arc base is used to be connected to the cylindrical valve, and a threading hole is passed through the connection column and the arc base.

[0009] Furthermore, the inner diameter of the threading hole gradually decreases from the end away from the arc-shaped base to the end of the arc-shaped base.

[0010] Furthermore, the inner radius of the threading hole is between 8.0 mm and 8.5 mm.

[0011] Furthermore, a connection reinforcement portion is provided between the connection column and the arc-shaped base.

[0012] Furthermore, the arc-shaped base is provided with a countersunk screw hole.

[0013] Furthermore, a rubber cushion layer is provided on the surface of the arc-shaped base that contacts the cylindrical valve.

[0014] Furthermore, a sealing ring is installed at the end of the threading hole away from the arc-shaped base.

[0015] Furthermore, a topological honeycomb structure is adopted inside the connection base.

[0016] The advantages of the utility model are: a specially designed and manufactured matching base enables a fixed connection between the cylindrical valve and the constraint pipeline, realizes guided constraint of the control wires, can prevent oxidation corrosion in a high humidity environment, rodent gnawing, and prevent short circuits, and can also increase service life, simplify later maintenance, and be beautiful and tidy.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the embodiments.

[0026] This embodiment provides a method for controlling wire restraint of a wet alarm valve group, comprising the following steps:

[0027] S10. Based on the actual situation on site, use modeling software to model the wet alarm valve group;

[0028] S20. Design the constraint pipeline 3 of the electrical circuit on the modeling software, and determine the direction and required size of the constraint pipeline 3;

[0029] S30. The straight pipe and elbow copper pipe fittings constraining the pipeline 3, and the connecting base connected to the cylindrical valve 1 and the control box 2 are designed using modeling software;

[0030] S40. Printing the base using 3D printing technology according to the designed base model;

[0031] S50. According to the design model of the constraint pipeline 3, the wires that originally need to be inserted into the corrugated casing are inserted into the constraint pipeline 3. The constraint pipeline 3 is connected and fixed with the alarm valve and the control box 2 through the connection base, such as Figure 5 and Figure 6 shown.

[0032] like Figure 1 As shown, the base designed by the modeling software includes a connecting base 4 at the cylindrical valve, and the connecting base 4 includes a connecting column 401, and the lower part of the connecting column 401 is integrally formed with an arc base 402, and the arc base 402 is used to connect to the cylindrical valve 1, and the connecting column 401 and the arc base 402 are penetrated by a threading hole 403. In this embodiment, the outer radius of the connecting column 401 is 11.5mm, and at the same time, the inner diameter of the threading hole 403 gradually decreases from the end away from the arc base 402 to the end of the arc base 402. During installation, the constraint pipeline 3 is inserted into the threading hole 403, and the changing inner diameter makes the constraint pipeline 3 more and more tight. In addition, because the copper pipe will be slightly deformed after on-site cutting, the design of the changing inner diameter of the threading hole 403 can ensure smooth installation. Preferably, the inner radius of the threading hole 1 403 away from the arc-shaped base 402 is 8.5 mm, and the inner radius of the end close to the arc-shaped base 402 is 8 mm.

[0033] When threading, the wire enters from the opening of the threading hole 1 403 away from the arc base 402, and passes out from the opening of the arc base 402 to enter the cylindrical valve 1. In order to improve the waterproof performance, the present embodiment also installs a sealing ring at the threading hole 1 403 away from the arc base 402.

[0034] Preferably, the arc base 402 of this embodiment is provided with a countersunk screw hole 405, which facilitates the screw connection and fixation of the arc base 402 and the cylindrical valve 1, and the countersunk screws ensure that the surface is flat after installation. A rubber cushion layer is provided on the surface where the arc base 402 contacts the cylindrical valve 1 to increase the connection tightness and waterproofness of the arc base 402 and the cylindrical valve 1.

[0035] Since the copper restraint pipe 3 is heavy, the connection column 401 and the arc base 402 are prone to breakage. In this embodiment, a connection reinforcement part 404 is provided between the connection column 401 and the arc base 402. Figure 2 As shown, the cylindrical valve of this embodiment is connected to the base 4 and adopts a topological honeycomb structure inside, which reduces its own weight, reduces materials and ensures structural strength.

[0036] like Figure 3 As shown, the base designed by the modeling software includes a connection base 5 at the control box. In the previously applied patent 202121680521.8, the original connection base 5 at the control box has two parts: a connection column and a wiring box. The overall structure is relatively high and narrow. When the constraint pipeline 3 connected to the base is replaced with a copper pipe, the pipeline has a large weight. After installation, the copper pipe is easy to shake, and the connection column and the wiring box are also easy to break. To solve this defect, the connection base 5 at the control box of this embodiment includes an integrally formed connection column 2 501 and a connection plate 502. A connection reinforcement part 2 503 is provided between the connection column 2 501 and the connection plate 502. The overall height of the base is 23mm, the height of the connection plate 502 is 8mm, the width of the connection plate 502 is 33mm, and the length of the connection plate 502 is 65mm. The wide and long connecting plate 502 provides a stable mounting surface for the connecting base 5. At the same time, the thin plate design makes the overall height of the connecting base 5 not too high, lowers the center of gravity, and increases the stability after being connected to the restraining pipeline 3. The second connecting column 501 and the connecting plate 502 are penetrated by a second threading hole 504, and the connecting plate 502 is used to connect and fix with the wet alarm valve group control box 2.

[0037] The outer radius of the second connecting column 501 of this embodiment is 11.5 mm, and at the same time, the inner diameter of the second threading hole 504 gradually decreases from the end away from the connecting plate 502 to the end of the connecting plate 502. During installation, the constraint pipe 3 is inserted into the second threading hole 504, and the changing inner diameter makes the constraint pipe 3 tighter and tighter. In addition, because the copper pipe will be slightly deformed after on-site cutting, the design of the changing inner diameter of the second threading hole 504 can ensure smooth installation. Preferably, the inner radius of the second threading hole 504 away from the end of the connecting plate 502 is 8.5 mm, and the inner radius close to the end of the connecting plate 502 is 8 mm.

[0038] When threading, the wire enters from the opening of the second threading hole 504 away from the connecting plate 502, and passes out from the opening of the connecting plate 502 to enter the control box 2. To improve the waterproof performance, the present embodiment also installs a sealing ring at the second threading hole 504 away from the connecting plate 502.

[0039] Preferably, the connection plate 502 of this embodiment is provided with a second countersunk screw hole 505, which is convenient for screw connection and fixing of the connection plate 502 and the control box 2, and the countersunk screws ensure a flat surface after installation. A rubber cushion layer is provided on the surface where the connection plate 502 contacts the control box 2 to increase the connection tightness and waterproofness of the connection plate 502 and the control box 2.

[0040] like Figure 4 As shown, the control box of this embodiment is connected to the base 5 with a topological honeycomb structure to reduce its own weight, reduce materials and ensure structural strength.

[0041] The above embodiments are only used to explain the concept of the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention using this concept shall fall within the protection scope of the present invention.
