Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline connection technology, specifically relating to an adapter for a continuous fiber reinforced thermoplastic material CBF composite pipe. Background Technology
[0002] Continuous fiber reinforced polyethylene (CBF) socket flange connection pipe is a coaxial balanced flow pipe, mainly used in fluid transmission and control systems. It is commonly found in hydraulic and pneumatic systems. In hydraulic systems, it is primarily used for liquid transmission, while in pneumatic systems, it is mainly used in automated equipment and production lines for transmitting compressed air. CBF composite pipe is a commonly used pipe material in urban water diversion and transmission, municipal water supply networks, urban stormwater and sewage networks, farmland irrigation, water conservancy and hydropower, petrochemical and other fields.
[0003] Currently, during the use of CBF composite pipes, due to the practical application requirement to connect two CBF composite pipes, there are situations where the connection is not tight and the sealing is poor, resulting in leakage of transported liquid into the pipe body and causing damage to the entire pipeline system.
[0004] Based on this, an adapter for a continuous fiber reinforced thermoplastic (CBF) composite pipe is researched and relates to. Utility Model Content
[0005] This utility model provides a continuous fiber reinforced thermoplastic (CBF) composite pipe adapter. In practical applications, when connecting two CBF composite pipes, this adapter is used. The adapter itself is a ring-shaped structure with an annular groove between the outer and inner circles. A rubber sealing gasket is placed inside the annular groove. Both ends of the adapter body have identical structures. Therefore, the two CBF composite pipes can be tightly connected to the two ends of the adapter body, respectively, resulting in strong sealing. This solves the problems of poor pipe end sealing, leakage of the transported medium, and pipe leakage that exist in existing continuous fiber reinforced polyethylene composite pipe connections.
[0006] This utility model is achieved through the following technical solution:
[0007] A continuous fiber reinforced thermoplastic (CBF) composite pipe adapter includes an adapter body, which is a ring structure. An annular groove is formed between the outer and inner rings of the adapter body. A rubber sealing gasket is installed in the annular groove, and the rubber sealing gasket is in close contact with the inner surface of the annular groove. After installation, the top of the inner ring is higher than the top of the rubber sealing gasket. The two end faces of the adapter body have the same structure.
[0008] Furthermore, in some embodiments of this utility model, the top height of the outer ring of the adapter body is the same as the top height of the inner ring of the adapter body.
[0009] Furthermore, in some embodiments of this utility model, the cross-section of the aforementioned rubber sealing ring gasket is circular.
[0010] Furthermore, in some embodiments of this novel plow, the circumference of the outer circle of the adapter body is greater than the width of the outer circle of the adapter body.
[0011] Furthermore, in some embodiments of this utility model, the circumferential width of the above-mentioned annular groove is greater than the wall thickness of the rubber sealing ring gasket.
[0012] Furthermore, in some embodiments of this novel plow, both ends of the adapter body are adapted and connected to CBF composite pipes.
[0013] Furthermore, in some embodiments of this utility model, the diameter of the CBF composite pipe is greater than or equal to the minimum diameter of the annular groove of the adapter body, and the diameter of the CBF composite pipe is less than or equal to the maximum diameter of the annular groove of the adapter body.
[0014] Furthermore, in some embodiments of this novel plow, the adapter body is an integrated plow structure.
[0015] Furthermore, in some embodiments of this utility model, when the CBF composite tube is connected to the adapter body, one end of the adapter body is first inserted into the interior of the CBF composite tube, guiding the end face of the CBF composite tube into the annular groove of the adapter body. Under the guidance of the adapter body, the CBF composite tubes connected to both ends of the adapter body form a clearance fit between the annular groove and the rubber sealing gasket installed in the annular groove and the contact end of the CBF composite tube, thus completing the sealed connection between the two CBF composite tubes and the two end faces of the adapter body respectively.
[0016] Furthermore, in some embodiments of this utility model, the adapter body is made of plastic, metal, or a composite material of plastic and metal.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1) The CBF composite pipe adapter described in this application is mainly for application scenarios where continuous fiber reinforced polyethylene composite pipes need to be connected, that is, it is specifically used for connecting continuous fiber reinforced thermoplastic CBF composite pipes.
[0019] 2) The continuous fiber reinforced thermoplastic CBF composite pipe adapter device described in this application has a ring-shaped body with an annular groove for installing a rubber sealing gasket between its outer and inner circles. After installation, the rubber sealing gasket is in close contact with the inner surface of the annular groove. Simultaneously, the top height of the rubber sealing gasket is lower than the inner circle height of the adapter body. This structural design of the adapter body facilitates a tight connection between one end face of the continuous fiber reinforced thermoplastic CBF composite pipe and the annular groove of the adapter body. Similarly, the other end of the adapter body is tightly connected to the other end of another CBF composite pipe. This allows for quick connection of two continuous fiber reinforced thermoplastic CBF composite pipes, achieving a sealing effect on the connection end faces of the continuous fiber reinforced thermoplastic CBF composite pipes.
[0020] 3) The adapter body in the CBF composite pipe adapter device of this application has the same structure on both ends, and can be connected to one CBF composite pipe respectively, so as to achieve a sealed connection of two CBF composite pipes with good sealing performance and no leakage.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the embodiments. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0025] Example 1:
[0026] like Figure 1 , Figure 2 As shown, an adapter for a continuous fiber reinforced thermoplastic (CBF) composite pipe includes an adapter body 1, which is a ring structure. An annular groove 2 is formed between the outer and inner rings of the adapter body 1. A rubber sealing gasket 3 is installed in the annular groove 2, and the rubber sealing gasket 3 is in close contact with the inner surface of the annular groove 2. After installation, the top of the inner ring is higher than the top of the rubber sealing gasket 3. The two end faces of the adapter body 1 have the same structure.
[0027] One end face of the adapter body 1 is a ring structure, and an annular groove is formed between the outer and inner circles of the adapter body 1. A rubber sealing gasket 3 is provided in the annular groove, and the rubber sealing gasket 3 is in close contact with the inner surface of the annular groove 2. When one end of the CBF composite tube is connected to one end face of the adapter body 1, one end of the adapter body 1 is first inserted into the interior of the CBF composite tube, guiding the end face of the CBF composite tube into the annular groove 2 of the adapter body 1. Under the guidance of the adapter body 1, the CBF composite tube connected to one end of the adapter body 1 forms a clearance fit between the annular groove 2 and the contact end of the rubber sealing gasket 3 installed in the annular groove 2 and the CBF composite tube, thus completing the sealed connection between the CBF composite tube and one end face of the adapter body 1.
[0028] Similarly, since the two end faces of the adapter body 1 have the same structure, both have an annular groove 2 between the inner and outer circles of the annular structure. A rubber sealing gasket 3 can be installed in the annular groove 2. The top height of the rubber sealing gasket 2 located in the annular groove 2 is lower than the top height of the inner circle. The side end of the adapter body 1 can be guided to be inserted into one end of the CBF composite tube, thus completing the connection of the two CBF composite tubes.
[0029] The top height of the outer circle of the adapter body 1 is the same as the top height of the inner circle of the adapter body 1.
[0030] Further specified, the cross-section of the rubber sealing gasket 3 is circular, and the circular rubber sealing gasket is an O-ring, which is installed in the annular groove 2 and in close contact with the inner surface of the annular groove 2 to form a clearance fit.
[0031] Further specified, the circumference of the outer circle of the adapter body 1 is greater than the width of the outer circle of the adapter body 1, the circumference of the annular groove 2 is greater than the wall thickness of the rubber sealing gasket 3, and both ends of the adapter body 1 are adapted and connected to the CBF composite pipe.
[0032] The diameter of the CBF composite pipe is greater than or equal to the minimum diameter of the annular groove 2 of the adapter body 1, and the diameter of the CBF composite pipe is less than or equal to the maximum diameter of the annular groove 2 of the adapter body 1.
[0033] The adapter body 1 is an integrated molding structure, and the adapter body 1 is made of plastic, metal, or a composite material of plastic and metal.
[0034] Example 2:
[0035] The continuous fiber reinforced thermoplastic (CBF) composite pipe adapter device described in Example 1, and the CBF pipe installation process are as follows: the CBF composite pipe adapter device plays a guiding role during the installation and connection of the CBF composite pipe. The smaller end of the adapter device first enters the interior of the CBF composite pipe, guiding the end face of the CBF composite pipe into the annular groove in the adapter device. Under the guidance of the CBF composite pipe adapter device, the CBF composite pipes connected to the two end faces of the CBF composite pipe adapter device can achieve rapid end-to-end alignment, realizing the connection of two CBF composite pipes together through the CBF composite pipe adapter device.
[0036] The CBF composite pipe end face is sealed. The CBF composite pipe adapter has annular grooves inside both end faces. Rubber sealing gaskets are installed in the annular grooves. After connection, the end face of the CBF composite pipe is in close contact with the rubber sealing gaskets in the annular grooves of the CBF composite pipe adapter, thus sealing the end face of the CBF composite pipe.
[0037] In this embodiment, the CBF composite pipe refers to a continuous fiber reinforced thermoplastic material pipe, preferably a continuous fiber reinforced polyethylene composite pipe.
