Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipeline reconstruction, and in particular to a joint for reconstruction of water supply pipelines in old residential areas. Background Art

[0002] Water supply pipeline refers to the pipeline system used to transport and distribute drinking water or industrial water. The specifications of water supply pipelines are determined by factors such as the amount of water to be transported, pressure requirements, pipeline length and layout. The diameter of the pipeline generally ranges from a few millimeters to several meters. Choosing the right specifications can ensure smooth water flow and water supply quality. In the water supply pipeline renovation project, pipe joints play a vital role. They are responsible for connecting and fixing each section of the pipeline to ensure the continuity and stability of the water supply. However, in the process of renovating old communities, traditional pipe joint designs are often directly exposed to the external environment and are easily affected by temperature changes and moisture erosion.

[0003] At present, there are some pipe joints on the market, which are usually made of metal materials and have a certain degree of durability. However, it is difficult to add insulation layers to the curved parts of these traditional joints, which makes it easy for water sources to freeze in low temperature environments. At the same time, due to the effects of moisture and condensation in the environment, the surface of the joints is prone to rust, thereby shortening their service life.

[0004] The water supply pipe joints in the existing technology have obvious deficiencies in anti-freeze and anti-corrosion, and cannot effectively cope with the environmental challenges faced by the pipe joints after the renovation of old communities, such as temperature changes and moisture erosion. At the same time, during the water pipe renovation, water flow back may occur, thus affecting the progress of the renovation work. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a joint for the renovation of water supply pipes in old communities, aiming to improve the problem that the pipe joints in old communities cannot effectively cope with the environmental challenges faced by them after the renovation, such as temperature changes and moisture erosion, and water backflow may occur during the renovation of water pipes, thereby affecting the renovation work.

[0007] Through the above technical scheme: the insulation layer and the joints made of corrosion-resistant materials can prevent water freezing and joint rust and rot, thereby extending the service life of the joints. By engaging the blocking column with the blocking groove, the limiting block slides in the slide groove, ensuring the stable movement of the check block, thereby effectively avoiding the occurrence of water flow backflow.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Reference Figure 2 , Figure 3 and Figure 4, the utility model provides an embodiment: a joint for the reconstruction of water supply pipelines in old communities, comprising two shells 1 and a check block 6, adjacent sides of the two shells 1 are fixedly installed with an insulation layer 3, the front and rear sides of the inner wall of the bottom insulation layer 3 are fixedly connected with a blocking block 4, adjacent sides of the two blocking blocks 4 are fixedly connected with a blocking column 5, the front and rear ends of the right side of the check block 6 are provided with a blocking groove 9, the left sides of the two blocking columns 5 are respectively engaged with the corresponding blocking grooves 9, the right bottom of the check block 6 is fixedly connected with a limiting block 7, the middle part of the inner bottom wall of the bottom insulation layer 3 is provided with a sliding groove 8, the bottom of the limiting block 7 is slidably connected with the sliding groove 8, the left and right sides of the bottom shell 1 are fixedly connected with a filter plate 11, the front and rear sides of the two shells 1 are fixedly connected with a transverse plate 10, and the two transverse plates 10 are provided with a disassembly mechanism 2 on the far side thereof;

[0041] Specifically, by providing the thermal insulation layer 3, the thermal insulation effect of the water flow temperature is effectively improved. The thermal insulation layer 3 is made of high-efficiency thermal insulation material, which can significantly reduce heat loss and ensure that the water flow maintains a stable temperature during transmission. This not only helps to reduce energy consumption, but also reduces the risk of water freezing, thereby ensuring the stable operation of the water supply system. Secondly, the connector adopts a shell 1 made of corrosion-resistant material, so that the connector can maintain good durability even in harsh environments. The corrosion-resistant material has excellent corrosion resistance and can resist the erosion of chemicals, microorganisms, etc. in the water, thereby effectively extending the service life of the connector. When the water flow is reversed, the check block 6 will be impacted by the reverse flow. The check block 6 will hit and move along the direction of the slide groove 8 under the guidance of the limiting block 7. As the check block 6 moves, it will engage with the two blocking blocks 4, and the two blocking columns 5 will also engage with the corresponding blocking grooves 9. In this way, the internal space of the joint is completely blocked, thereby effectively avoiding the occurrence of water backflow. The design of this backflow protection device not only improves the work efficiency, but also reduces the potential losses caused by backflow. During the water supply pipeline renovation, backflow may cause pollutants and impurities in the pipeline to flow back to the water supply system, thereby affecting the water supply quality. By adopting this joint with backflow protection function, this problem can be effectively avoided to ensure the smooth progress of the renovation process.

[0042] Reference Figure 1 and Figure 2 , a protective shell 208 is provided on the left side of the two movable rods 206, and the right side of the two protective shells 208 is rotatably connected to the corresponding top connecting shell 201 through a hinge; the upper and lower sides of the two shells 1 are fixedly connected with flanges 12, and the inner walls of the multiple flanges 12 are equidistantly provided with multiple mounting holes;

[0043] Specifically, the protective shell 208 can protect the left side of the movable rod 206, and the flange 12 makes it easier to install and fix the joint.

[0044] Reference Figure 1 , Figure 2 and Figure 5 The disassembly mechanism 2 includes a plurality of connection shells 201, and the adjacent sides of the plurality of connection shells 201 are fixedly connected to the middle part of the opposite side of the corresponding horizontal plate 10, and the front and rear sides of the inner top walls of the two top connection shells 201 are fixedly connected with a clamping rod 202, and the front and rear ends of the right sides of the inner walls of the two bottom connection shells 201 are fixedly connected with a return spring 203, and the left sides of the plurality of return springs 203 are fixedly connected with a movable plate 204, and the front and rear ends of the left sides of the two movable plates 204 are provided with a clamping groove 205, and the bottoms of the plurality of clamping rods 202 are respectively clamped with the corresponding clamping grooves 205, and the left sides of the two movable plates 204 are fixedly connected with a movable rod 206;

[0045] Specifically, by pressing the two movable rods 206 to the right, the movable plate 204 can be driven to move to the right together. When the movable plate 204 moves to the right, the locking groove 205 and the locking rod 202 are gradually separated, thereby releasing the locked state. After the locking rod 202 and the movable plate 204 are unlocked, the multiple connecting shells 201 are in an openable state. At this time, only the outer shell 1 needs to be pulled upwards to easily separate the multiple connecting shells 201 from the outer shell 1 to complete the disassembly work. Conversely, the installation of the joint can be achieved. Since there is no need to use additional tools, the operator only needs to complete the installation and disassembly of the joint through simple pressing and pulling actions, which greatly reduces the labor cost of the operator.

[0046] Reference Figure 2 and Figure 5 The left and right sides of the top walls of the two bottom horizontal plates 10 are provided with fixing grooves 16, and the left and right sides of the bottom walls of the two top horizontal plates 10 are fixedly connected with fixing columns 15, and the bottom ends of the two fixing columns 15 are respectively engaged with the corresponding fixing grooves 16; the front and rear sides of the bottom wall of the top shell 1 are fixedly connected with sealing plates 13, and the front and rear sides of the top wall of the bottom shell 1 are provided with sealing grooves 14, and the bottoms of the two sealing plates 13 are respectively engaged with the corresponding sealing grooves 14;

[0047] Specifically, the bottom ends of the two fixing columns 15 are respectively engaged with the corresponding fixing grooves 16, so that the connection stability between the two shells 1 is improved, and the bottom ends of the two sealing plates 13 are respectively engaged with the corresponding sealing grooves 14, so that the sealing between the shells 1 is improved, and the sealing effect is effectively improved.

[0048] Reference Figure 4 and Figure 5 The front and rear sides of the check block 6 and the adjacent sides of the two barrier blocks 4 are provided with inclined surfaces, and the front and rear sides of the check block 6 and the adjacent sides of the two barrier blocks 4 are engaged with each other; the outer wall bottoms of the two top connection shells 201 are fixedly connected with wear-resistant rings 207;

[0049] Specifically, by providing inclined surfaces on the front and rear sides of the check block 6 and the adjacent sides of the two barrier blocks 4, the check block 6 has a better effect in preventing backflow, and the wear between the multiple connection shells 201 is reduced by the wear-resistant ring 207.

[0050] Working principle: When it is used, the joint is fixed in the required position by the flange 12. The setting of the insulation layer 3 improves the insulation of the water temperature, thereby reducing the possibility of water freezing. The outer shell 1 made of corrosion-resistant material makes the joint less prone to rust and rot, thereby extending the service life of the joint. When the water supply pipeline is renovated and the water flow is reversed, the check block 6 is impacted by the reverse flow, and thus moves along the chute 8 under the guidance of the limiting block 7, so that the check block 6 is engaged with the two barrier blocks 4, and the two barrier columns 5 are engaged with the corresponding barrier grooves 9. At this time, the internal space of the joint is blocked, thereby avoiding the reverse flow of water and causing The situation that affects the transformation of the water supply pipeline occurs, the work efficiency is improved, and by pressing the two movable rods 206 to the right, the movable plate 204 and the movable rod 206 are moved to the right together, so that the locking groove 205 opened on the left side of the movable plate 204 is separated from the corresponding locking rod 202, and then the locking rod 202 and the movable plate 204 are unlocked. At this time, the multiple connecting shells 201 are in an openable state, and by pulling the outer shell 1 upwards, the multiple connecting shells 201 and the two outer shells 1 are disassembled, and vice versa, the installation is completed, so that the joint is easy to install and disassemble, avoids the situation of using additional tools for installation and disassembly, and reduces the labor cost of operators.
