Description

TECHNICAL FIELD

[0001] The present application relates to a sealing device, more particularly to a flexible pipe sealing device. BACKGROUND

[0002] Pipe sealing is an effective sealing and protection operation on the connecting end of the pipe conveying dangerous gas and liquid, and the connecting end is sealed by secondary sealing equipment, so that when the gas and liquid leak, the secondary protection can be realized through the sealing equipment to avoid environmental pollution caused by dangerous gas and liquid leakage.

[0003] However, the existing sealing device is very diverse, in order to meet market demand, how to reduce the cost of the sealing device, how to make the sealing device easy to install. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a flexible pipe sealing device which can reduce production cost and make installation more convenient.

[0005] To achieve the above purpose, the present application provides the following technical scheme: a flexible pipe sealing device comprising a film, the film is fixedly connected along the length direction of the middle line of the width direction of the two sides, and a storage part is formed in the middle and a pipe part is formed on both sides.

[0006] The first connecting piece is arranged on the inner side of the storage part and the pipe part, and the second connecting piece is arranged on the outer side of the storage part and the pipe part.

[0007] A method for using the flexible pipe sealing device, comprising installing the sealing device on the pipe.

[0008] The sealing device is pumped by a vacuum device.

[0009] The sealing device is concave inward.

[0010] The sealing device is closed.

[0011] In summary, the present application has the following advantages: the first layer sealing operation is realized by high-strength glue, the outer edge of the film is adsorbed and double-sided pasted by magic tape, double-layer fixation is realized by one layer of magic tape, the installation method is not only simple, but also effectively reduces the product cost while ensuring the sealing performance.

[0012] In addition, through the design of the film, the film is preferably a transparent film, and the leakage amount of liquid can be directly observed. For gas leakage, the film is deflated by preforming a negative pressure in the film, and when the gas leaks, the film expands, so that the gas leakage condition can be known in the first time, without the need to design other observation devices, thereby greatly reducing the cost.

[0020] The application will be further described in detail below in combination with the drawings and examples. Identical parts are denoted by identical reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular part.

[0021] REFERENCE Figures 1 to 6 To achieve the above object, the application provides the following technical scheme: a flexible pipe sealing device, comprising a film 1, the two sides of the film 1 in the width direction are fixedly connected along the length direction of the middle line, and a storage part 2 located in the middle and a pipe part 3 located on both sides are formed.

[0022] A first connecting piece is arranged on the inner side of the storage part 2 and the pipe part 3, and a second connecting piece is arranged on the outer side of the storage part 2 and the pipe part 3.

[0023] The design of the present application has the following 5 implementation methods, and has the following effects:

[0024] The first layer sealing operation is realized by high-strength glue, and then the outer edge of the film 1 is adsorbed and double-sided pasted by the magic tape 4. Double-layer fixation can be realized by one layer of magic tape 4. This installation method is not only simple, but also effectively reduces the product cost while ensuring the sealing performance.

[0025] In addition, through the design of the film 1, the film 1 is preferably a transparent film 1. For liquid leakage, the leakage amount can be observed directly. For gas leakage, the film 1 is made into negative pressure in advance, so that the film 1 is concave. When the gas leaks, the film 1 expands, so that the gas leakage condition can be known in the first time without the need to design other observation equipment, thereby greatly reducing the cost.

[0026] As shown in Figure 1 , the first connecting piece is glue, which is used for pasting and arranging along the length direction center line of the two sides of the film 1 in the width direction.

[0027] The second connecting piece is a magic tape 4, one end of which is pasted to one side of the film 1, and the other end is bent and pasted to the other side of the film 1.

[0028] Further design, a cut is arranged at the magic tape 4 between the pipeline part 3 and the storage part 2, which is used for improving the sealing effect of the magic tape 4.

[0029] As shown in Figure 2 , the first connecting piece includes a connecting plate 5 arranged inside the film 1, a plurality of connecting holes 51 are arranged on the connecting plate 5, and mounting holes 11 are arranged on both sides of the film 1.

[0030] The film 1 and the connecting plate 5 are stably connected by bolts or fasteners, snaps and the like.

[0031] As shown in Figure 3 , the connecting plate 5 and the two ends of the film 1 are provided with mounting gaps 12.

[0032] The design of the mounting gap 12 facilitates the formation of a flat mounting surface when the adhesive tape and the clamp are installed, thereby ensuring the long-term durability of the equipment.

[0033] The second connecting piece includes an adhesive tape and a clamp which are bound at the mounting gap 12.

[0034] As shown in Figure 4 , the connecting plate 5 is provided with mounting grooves at both ends, and a U-shaped gasket 6 is arranged inside the film 1.

[0035] As described above, the pipeline part 3 of the above-mentioned four embodiments can be additionally provided with the design of the adhesive tape and the clamp, thereby further improving the overall anti-leakage capability of the equipment.

[0036] As shown in Figure 5 and Figure 6 The outer side of the film 1 is provided with a protective cover 7. Corresponding to the square pipe and the circular pipe respectively, a shell is additionally arranged on the outer periphery of the pipe, which comprises an upper shell and a lower shell, a ring for connecting the two, and a fixing bolt.
