Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a fiberglass pipe that is easy to connect. Background Technology

[0002] Fiberglass reinforced plastic (FRP) pipes, also known as glass fiber reinforced plastic pipes, have been widely used in chemical, municipal water supply and drainage, sewage treatment, and oil and gas transportation fields due to their advantages such as corrosion resistance, light weight, high strength, and low fluid resistance. However, with the continuous expansion of their application scenarios and the increase in project scale, traditional FRP pipe connection methods have gradually revealed problems such as low efficiency, poor sealing, and insufficient adaptability. "Easy-to-connect FRP pipes" have been gradually developed to solve these pain points.

[0003] However, if the connection structure contains metal components (such as clamps and flanges), the material difference between metal and fiberglass will lead to different coefficients of thermal expansion. In environments with large temperature differences (such as open-air pipes exposed to the sun in summer and low temperatures in winter), gaps may be generated due to thermal expansion and contraction, affecting the sealing performance. At the same time, the corrosion of metal components may also indirectly weaken the connection strength.

[0004] Therefore, we provide a fiberglass pipe that is easy to connect to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fiberglass pipe that is easy to connect, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fiberglass pipe that is easy to connect, comprising a fiberglass pipe body and a plug-in snap-fit ​​fixing and auxiliary sealing fixing mechanism, wherein the plug-in snap-fit ​​fixing and auxiliary sealing fixing mechanism is provided on one side of the fiberglass pipe body; The plug-in snap-fit ​​fixing and auxiliary sealing fixing mechanism includes a one-sided plug-in fixing component, an embedded auxiliary snap-fit ​​component, and a threaded sealing snap-fit ​​secondary fixing component. A one-sided plug-in fixing component is provided on one side of the fiberglass pipe body, an embedded auxiliary snap-fit ​​component is provided on the inner side of the other side of the fiberglass pipe body, and a threaded sealing snap-fit ​​secondary fixing component is provided in the middle of the fiberglass pipe body.

[0007] Preferably, the one-sided insertion fixing assembly includes a first auxiliary snap-fit ​​collar, a steel snap-fit ​​sleeve, and an auxiliary snap-fit ​​fixing block. The first auxiliary snap-fit ​​collar is fixedly connected to the outer edge of the fiberglass pipe body, and a steel snap-fit ​​sleeve is fixedly connected to one side of the fiberglass pipe body. The auxiliary snap-fit ​​fixing block is fixedly connected to the surface of the steel snap-fit ​​sleeve by a threaded connection.

[0008] Preferably, the embedded auxiliary snap-fit ​​assembly includes a second auxiliary snap-fit ​​collar, a rubber sealing strip, and a fixed snap-fit ​​sleeve. The second auxiliary snap-fit ​​collar is fixedly connected to the other edge of the fiberglass pipe body, the rubber sealing strip is fixedly sleeved on the inner side of the fiberglass pipe body, and the fixed snap-fit ​​sleeve is threadedly fixed on the inner side of the fiberglass pipe body.

The sealing fixing collar is movably sleeved in the middle of the fiberglass pipe body. The limiting rubber gasket is adhered and fixed to the inner side of the sealing fixing collar. The edge of the sealing fixing collar is threadedly connected to the connecting threaded sealing rod, and the outer end of the connecting threaded sealing rod is threadedly connected to the adjusting threaded knob.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a plug-in snap-fit ​​fixing and auxiliary sealing fixing mechanism, this utility model achieves primary fixing of the fiberglass pipe through the inner snap-fit ​​rotational plug-in fixing, whereby the auxiliary snap-fit ​​fixing block and the inner fixing snap-fit ​​sleeve interlock. Furthermore, a rubber sealing strip is fixedly fitted inside the connection point of the two fiberglass pipe bodies, further ensuring a tight and sealed connection. After the two fiberglass pipes are connected and fixed, the outer threaded sealing snap-fit ​​secondary fixing component performs secondary snap-fit ​​fixing at the joint of the fiberglass pipe body. The limiting rubber gasket inside the sealing fixing collar assists in fixing the first and second auxiliary snap-fit ​​collars on the outer side of the fiberglass pipe body. Since the limiting rubber gaskets are all made of rubber, they can still achieve good fixing and sealing under different weather conditions. Attached Figure Description
