Description

Technical Field

[0001] This utility model relates to the field of pipe fittings technology, and in particular to a crossover tee assembly. Background Technology

[0002] In actual construction, when a pipeline crosses a parallel pipeline, a combination of tees and elbows is usually used to achieve the crossing between the pipelines. This crossing method has the following problems: In some narrow spaces, the lower side of the elbow often overlaps the lower pipeline. Even if some elbows are not in contact with the lower pipeline immediately after construction, factors such as soil settlement may cause the lower side of the elbow to come into contact with the lower pipeline. Under the action of fluid inside the pipeline, the pipeline will often vibrate. The vibration is transmitted through the elbow, which can easily lead to pipeline wear or loosening at the interface between the elbow and the tee. Utility Model Content

[0003] To address the shortcomings of existing methods for crossing pipelines, which easily cause pipe wear and loosening of joints, this invention proposes a crossing-type tee assembly to prevent pipe wear and improve joint reliability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A crossover tee assembly includes a tee, a connecting pipe, a reinforcing member, and an elastic sleeve. The tee includes a straight pipe section and a bend section. One end of the bend section is connected to the middle of the straight pipe section, and the other end of the bend section is provided with a socket. The socket has grooves on both the front and rear sides of its outer periphery. The reinforcing member includes a support ring and a locking key. The support ring is sleeved on the end of the connecting pipe, and the inner periphery of the support ring fits against the outer periphery of the connecting pipe. The locking key is fixedly connected to both the front and rear sides of the outer periphery of the support ring and engages with the grooves. The connecting pipe is sealed and inserted into the socket of the bend section. The elastic sleeve is sleeved on the outside of the connecting pipe and is located above the pipe to be crossed.

[0005] Furthermore, the slot and the key are reinforced with glue.

[0006] Furthermore, multiple fixing blocks are fixedly connected to the outer periphery of the socket, and the aforementioned slot is formed between two fixing blocks.

[0007] Furthermore, the distance between the lower side of the elastic sleeve and the pipe is d, 0 <d<10mm。

[0008] Furthermore, the end of the key is chamfered to facilitate insertion into the card slot.

[0009] Furthermore, the elastic sleeve is made of sponge material.

[0010] Furthermore, an annular groove is provided on the inner circumference of the socket, and a sealing ring is installed in the annular groove, which fits with the outer circumference of the end of the connecting pipe.

[0011] Through the above improvements, the tee assembly of this utility model has the following beneficial effects: 1. It can prevent pipe wear and make the joints more secure; 2. By cutting connecting pipes to different lengths, different distances can be traversed; 3. Easy to assemble and install. Attached Figure Description

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0017] Figures 1 to 4 This is a schematic diagram of the cross-type tee assembly of this utility model, wherein... Figure 1 The dimensions of the tee assembly are defined in the text for describing the technical solution. The tee assembly of this invention includes a tee, a connecting pipe 9, a reinforcing member, and an elastic sleeve 10. The tee includes a straight pipe section 3 and a bent pipe section 4. The tee assembly of this invention is used to cross a pipe 200 parallel to the side of the straight pipe section 3. One end of the bent pipe section 4 is connected to the middle of the straight pipe section 3, and the other end of the bent pipe section 4 extends upwards towards the pipe to be crossed and is provided with a socket 5. The socket 5 has grooves 6 on its outer periphery. The reinforcing member includes a support ring 7 and a retaining key. 8. The support ring 7 is fitted on the end of the connecting pipe 9. The support ring 7 can slide left and right along the connecting pipe 9. The inner circumference of the support ring 7 fits against the outer circumference of the connecting pipe 9. The aforementioned key 8 is fixedly connected to the front and rear sides of the outer circumference of the support ring 7. The key 8 is adapted to the slot 6. The key 8 is inserted into the slot 6. The upper and lower sides of the slot 6 support the key 8. The end of the connecting pipe 9 is coated with glue. The connecting pipe 9 is sealed and inserted into the socket 5 of the bend section 4. The end of the connecting pipe 9 is not easy to come out of the socket 5. The elastic sleeve 10 is fitted on the outside of the connecting pipe 9. The elastic sleeve 10 is located above the pipe to be crossed.

[0018] The working principle of the tee assembly is as follows: Figure 3, two tees are symmetrically placed on the left and right sides of the pipeline to be crossed, the bent pipe section 4 of the left tee faces right, and the right tee faces left. A connecting pipe 9 of appropriate length is selected according to the distance between the sockets 5 of the bent pipe sections 4 of the left and right tees. The connecting pipe 9 is a plastic round pipe, which is convenient for cutting according to the required crossing distance. An elastic sleeve 10 is sleeved on the connecting pipe 9, reinforcing members are sleeved at both ends of the connecting pipe 9, glue is applied to both ends of the connecting pipe 9, then the connecting pipe is inserted into the sockets 5 at the ends of the bent pipe sections 4 of the tees, and the clamping keys 8 of the reinforcing members are clamped into the clamping grooves 6. So far, the tee assembly is installed, as shown in Figure 1 . Through the above arrangement, the elastic sleeve 10 separates the connecting pipe 9 from the pipeline, preventing the connecting pipe 9 from directly contacting the pipeline. When the connecting pipe 9 or the pipeline vibrates, the elastic sleeve 10 functions to buffer and absorb vibration, avoiding pipeline wear, and at the same time reducing the vibration at the connection between the connecting pipe 9 and the socket 5 to prevent loosening between the connecting pipe 9 and the socket 5. In addition, since the upper and lower sides of the clamping key 8 are supported by the clamping grooves 6, up-down relative movement between the socket 5 and the end of the connecting pipe 9 is prevented, further avoiding leakage between the connecting pipe 9 and the socket 5.

[0019] In one embodiment, glue is used for reinforcement between the clamping groove 6 and the clamping key 8 to prevent the clamping key 8 from disengaging from the clamping groove 6.

[0020] In one embodiment, as shown in Figure 3 , a plurality of fixing blocks 11 are fixedly connected to the outer periphery of the socket 5, and the above-mentioned clamping groove 6 is formed between two adjacent fixing blocks 11. Specifically, two fixing blocks 11 are vertically and fixedly connected to the front side of the socket 5 by welding or fusion welding to form the front-side clamping groove 6, and two fixing blocks 11 are vertically and fixedly connected to the rear side of the socket 5 by welding or fusion welding to form the rear-side clamping groove 6.

[0021] In one embodiment, as shown in Figure 4 , when the tee assembly has just been installed, the distance from the lower side of the elastic sleeve 10 to the pipeline is d, where 0 < d < 10 mm, so that the elastic sleeve 10 is kept as far as possible out of contact with the pipeline to prevent vibration transmission between the pipeline and the tee assembly.

[0022] In one embodiment, as shown in Figure 2 , the end of the clamping key 8 is provided with a chamfer 12 that facilitates insertion into the clamping groove 6.

[0023] In one embodiment, the elastic sleeve 10 is made of sponge material.

[0024] In one embodiment, as shown in Figure 4 , an annular groove is provided on the inner periphery of the socket 5, and a sealing ring 13 is installed in the annular groove. The sealing ring 13 cooperates with the outer periphery of the end of the connecting pipe 9 to improve the sealing performance between the connecting pipe 9 and the socket 5.

[0025] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
