Description

Technical Field

[0001] This utility model belongs to the field of pipe fitting sealing inspection technology, specifically relating to a sealing inspection device applicable to various pipe diameters and capable of simultaneously inspecting multiple pipe fittings. Background Technology

[0002] Currently, most devices for testing the seal of pipe fittings use radial sealing, which involves inserting a plug with a sealing ring into the inner hole of the pipe end to achieve a seal. Radial sealing is necessary for thin-walled pipe fittings with a diameter less than 19mm. However, for thicker-walled pipe fittings with a diameter greater than 19mm, radial sealing presents the following problems: 1. The existence of a sealing blind zone affects the accuracy of the test; 2. Different diameter pipe fittings require different specifications of sealing plugs, resulting in a wide variety of parts, high manufacturing costs, and frequent replacements, which affects testing efficiency.

[0003] Therefore, there is an urgent need for a pipe sealing testing device that can adapt to different pipe diameters, reduce the number of parts, and improve testing efficiency. Utility Model Content

Multiple pipe end sealing devices are provided on the upper part of both ends of the base frame. Two pipe end sealing devices facing each other at both ends form a group for sealing both ends of a pipe fitting. Thus, multiple groups of pipe fitting sealing assembly groups capable of simultaneously sealing multiple pipe fittings are formed on the base frame. Each of the pipe end sealing devices includes a cylinder, the rear end of which is fixed to a rear cylinder mounting seat on the base frame, and the front end of which is fixed to a front cylinder mounting seat on the base frame; The front cylinder mounting base is provided with a guide sleeve in the middle, and the piston rod of the cylinder passes through the guide sleeve for telescopic guidance; A sealing element mounting plate is fixedly connected to the piston rod of the cylinder, and a sealing top cover or radial plug is detachably connected to the sealing element mounting plate.

[0006] Further defining the above solution, the sealing top cover is connected to the sealing element mounting plate by screws, and the sealing top cover has a disc-shaped structure with an outer diameter larger than the outer diameter of the pipe being sealed.

[0007] As a further limitation of the above scheme, the sealing top cover is made of plastic.

[0008] Further defining the above solution, the radial plug includes a plug body, which is connected to the sealing mounting plate by screws, and a sealing ring is fitted around the outer periphery of the plug body.

[0009] Further specifying the above solution, the sealing top cover is suitable for pipe fittings with a diameter of 19 mm or more, and the radial plug is suitable for thin-walled pipe fittings with a diameter of less than 19 mm.

[0010] As a further limitation of the above scheme, a protective cover is provided on the upper part of the base frame and outside the pipe end sealing device.

[0017] Please see Figure 1-5 The embodiments of this utility model are described in detail below.

[0018] like Figure 1-2 As shown, the general-purpose multi-pipe synchronous sealing testing device includes a base frame 1. Multiple pipe end sealing devices 2 are installed on the upper parts of both ends of the base frame 1. Each group consists of two opposing sealing devices used to seal both ends of a pipe fitting. Multiple groups can be installed on the base frame 1 to achieve simultaneous testing of multiple pipe fittings.

[0019] like Figure 1As shown, each pipe end sealing device 2 includes a cylinder 3. The rear end of the cylinder 3 is fixed to the rear cylinder mounting seat 4, and the front end is fixed to the front cylinder mounting seat 5. A guide sleeve 6 is provided in the middle of the front cylinder mounting seat 5. The piston rod of the cylinder 3 passes through the guide sleeve 6 for telescopic guidance. A sealing element mounting plate 7 is fixedly connected to the piston rod. A sealing top cover 8 or a radial plug 9 can be installed on the sealing element mounting plate 7 according to the pipe diameter and wall thickness specifications.

[0020] like Figure 3 As shown, the sealing top cover 8 is a disc-shaped plastic part, which is connected to the sealing mounting plate 7 by screws. It is suitable for pipes with a diameter of 19mm or more, and its outer diameter is larger than that of the pipe. The seal is achieved by pressing the end face.

[0021] like Figure 4 As shown, the radial plug 9 includes a plug body 10 and a sealing ring 11, which are connected to the sealing mounting plate 7 by screws. It is suitable for thin-walled pipes with a diameter of less than 19 mm and achieves radial sealing by inserting into the inner hole of the pipe.

[0022] like Figure 5 As shown, a clamping mechanism 12 is provided in the middle of the base frame 1 for clamping pipe fittings and improving testing stability. The clamping mechanism 12 includes a slide rail 13, on which multiple sets of clamp assemblies 14 are provided corresponding to the number of sets of pipe end sealing devices 2. Each set of clamp assemblies 14 includes a fixed clamp 15 and a movable clamp 16 arranged opposite to each other. The fixed clamp 15 is fixed to the slide rail 13 by screws and oblong holes, and its fixed position can be adjusted. The movable clamp 16 is slidably connected to the slide rail 13 through a lower T-shaped slider 17. A clamp cylinder 18 is fixed to one end of the slide rail 13. The piston rod of the clamp cylinder 18 is connected to the adjacent movable clamp 16 through a connecting rod 19. Adjacent movable clamps 16 on the slide rail 13 are also connected to each other through connecting rods 19. The clamp cylinder 18 drives multiple movable clamps 16 to move synchronously through the connecting rods 19, cooperating with the fixed clamps 15 to clamp the pipe fittings.

[0023] The upper part of the base frame 1 is equipped with a protective device 20 for safety protection and to ensure safe operation.

[0024] Working principle: During operation, select either the sealing cap 8 or the radial plug 9 based on the pipe diameter. Place the pipe in the clamping mechanism 12, and activate the clamp cylinder 18 to clamp the pipe between the moving clamp 16 and the fixed clamp 15. Then, activate the cylinder 3 of the pipe end sealing device 2 to push the sealing mounting plate 7 forward, causing the sealing cap 8 or radial plug 9 to contact and seal the end of the pipe. Introduce a test medium (such as air or water pressure) and observe the pressure change to determine the sealing performance. After the test is completed, the cylinder 3 retracts, the clamp releases, and the pipe is removed.

[0025] This utility model has a reasonable structure, is easy to operate, and is highly adaptable, making it particularly suitable for sealing testing of pipe fittings of various specifications and in large quantities.
