Description

Technical Field

[0001] The utility model relates to the technical field of pipeline closing, in particular to a glass fiber reinforced plastic pipeline closing connection device. Background Art

[0002] FRP pipes are widely used in the water supply and drainage industry due to their light weight, high strength, corrosion resistance and good hydraulic performance. The length of a FRP pipe is generally 12m. The pipes are mainly connected by socket. The inner diameter of one end of the FRP pipe is larger, which is the socket, and the outer diameter of the other end is slightly smaller than the inner diameter of the socket, which is the spigot. The spigot is slotted to place a rubber ring for sealing. In the actual construction of FRP pipe projects, due to reasons such as segmented construction, it is often necessary to close the two sections of FRP pipelines. Since the socket connection has a length of spigot inserted into the socket, the total length of the pipeline will be less than the actual connection length. If the traditional socket connection method is used for closing, the length of the pipe that can be put in can only be the connection length. When the pipe is connected by socket, there will be a gap at the closing point, and the closing connection cannot be achieved. At this time, the on-site butt-jointing paste process can only be used for manual operation, which is not only time-consuming and labor-intensive, but also limited by the on-site environment and conditions, and the quality cannot be effectively guaranteed.

[0018] Through the closing connection method of the double intubation tube 4 and the straight tube 5, a double intubation tube 4 with sockets 2 at both ends and a straight tube 5 with sockets 1 at both ends are prepared, and the double intubation tube 4 is inserted into the straight tube 5 so that the total length is less than the closing length, and they are hoisted together to the closing position, such as Figure 5 (a); move the double cannula 4 and insert its socket 2 into the glass fiber reinforced plastic pipe to be closed ( Figure 4 The figure shows the socket 1 of the glass fiber reinforced plastic pipe. Figure 5 (b) as shown; then pull out the straight tube 5 to a certain length and sleeve it onto the socket 2 of the glass fiber reinforced plastic pipe to be closed, thereby achieving a closed connection, such as Figure 5 As shown in (c), it saves time and effort and has good connection effect;

[0019] The total length of the double-insertion tube 4 is less than the length of the position to be closed, and the sum of the length of the straight tube 5 and the length of the double-insertion tube 4 is greater than the length of the position to be closed.

[0020] The double-insert pipe 4, the straight pipe 5 and the glass fiber reinforced plastic pipe to be closed are connected by a socket connection through a sealing ring 3. The connection size of the double-insert pipe 4 and the straight pipe 5 matches the socket size of the glass fiber reinforced plastic pipe to be closed, meeting the connection sealing requirements.

[0021] It also includes two clamping structures 6 , which are symmetrically assembled on one side of the inner wall of the straight tube 5 , and the clamping structures 6 play the role of clamping the double insert tubes 4 .
