Description

Technical Field

[0001] This utility model relates to the field of pipeline valve structure technology, and in particular to a PE pipeline valve that is easy to install. Background Technology

[0002] In municipal water supply, agricultural irrigation, and industrial fluid transportation, PE pipes have become the mainstream fluid transportation carrier due to their advantages of corrosion resistance, light weight, and long service life. As the core component for controlling the flow of media, the connection performance of PE pipe valves directly affects the stability of the system.

[0003] Existing PE pipe valve connection methods have obvious defects: flange connection requires multiple accessories such as flanges and bolts. During installation, precise alignment and bolt tightening are required one by one, which is cumbersome and the bolts are prone to corrosion later, making maintenance and disassembly difficult; hot melt welding has extremely high requirements for operating parameters. Improper temperature or time control can easily cause leakage at the weld. Moreover, the valve and pipe cannot be separated after welding. Replacement or maintenance requires cutting the pipe, resulting in material waste and project delays. In addition, although some valves with simple connection structures simplify the installation process, their sealing performance is insufficient. During long-term use, they are prone to loosening and leakage due to fluctuations in medium pressure and environmental vibrations. At the same time, the fixed structure lacks a stable locking design, making the pipeline prone to displacement.

[0004] Therefore, a PE pipe valve that is easy to install is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems and propose a PE pipe valve that is easy to install, has reliable sealing, is stable to fix, and is easy to maintain.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PE pipe valve that is easy to install, comprising a PE pipe valve body, a valve handle in the middle of the PE pipe valve body, and connecting components fixedly assembled at both ends of the PE pipe valve body, with flat limiting pins detachably assembled between the connecting components.

[0007] Preferably, the connecting assembly includes two short pipe sleeves, a rubber embedded ring, an internal hexagonal threaded limiting head, a first-tooth curved surface clamping plate, a rubber bending pad, and a second-tooth curved surface clamping plate. The two short pipe sleeves are integrally formed with both ends of the PE pipe valve body. The rubber embedded ring is bonded and fixed inside the short pipe sleeve and located at one end close to the PE pipe valve body. The internal hexagonal threaded limiting head is rotatably assembled in the threaded through hole on the bottom surface of the short pipe sleeve. The first-tooth curved surface clamping plate is sleeved on the clamping head at the upper end of the internal hexagonal threaded limiting head. The rubber bending pad is bonded and fixed in the internal groove of the short pipe sleeve and corresponds to the position of the first-tooth curved surface clamping plate. The second-tooth curved surface clamping plate is bonded and fixed to the bottom surface of the rubber bending pad.

[0008] Preferably, the inner side of the rubber embedded ring has multiple annular grooves evenly distributed.

[0009] Preferably, the lower end of the internal hexagonal threaded limiting head has a through hole, through which the flat limiting pin passes to achieve detachable assembly between the connecting components and to lock the internal hexagonal threaded limiting head to prevent it from rotating.

[0010] Preferably, the material hardness of the first and second toothed curved surface clamps is higher than that of the PE pipe material.

[0011] The beneficial effects of this utility model are as follows: By setting the connecting component and the flat limiting long nail, the core function of the connecting component and the flat limiting long nail is to achieve a firm and sealed connection between the PE pipe and the valve, and to ensure a stable fixed state and facilitate maintenance.

[0012] The connection is strong and the seal is reliable: the connection component provides an installation base through a short pipe sleeve, the rubber embedded ring enhances the sealing and limiting performance, and the No. 1 and No. 2 toothed curved surface clamps hold the pipe in both directions; combined with the elastic buffer of the rubber bending pad, it not only avoids pipe damage, but also ensures that the pipe will not loosen or shift, while preventing media leakage.

[0013] Long-lasting and stable fixed state: The flat limiting pin penetrates the internal hexagonal thread limiting head and bends to lock it, which can prevent it from rotating due to vibration, medium pressure and other factors, thereby maintaining the clamping force of the clamp on the pipe, ensuring the long-term stability of the connection and avoiding loosening problems during use.

[0014] Easy installation and maintenance: During installation, simply insert the pipe, rotate the internal hexagonal limit head, and insert the long nail to complete the fixation; during disassembly and maintenance, simply pull out the long nail and rotate the limit head in the opposite direction to loosen the pipe, without the need for complicated tools or destructive operations, greatly simplifying the process.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] See Figure 1-4 As shown, the PE pipeline valve body 1, as the core load-bearing component of the entire PE pipeline valve, is the installation basis for the valve handle 2 and the connecting assembly 3. It integrates the valve's control and connection functions, ensures the stability of the overall valve structure, and provides the main support for the on / off control of the PE pipeline.

[0019] The valve handle 2 is installed in the middle of the valve body 1 of the PE pipeline and is an operating component for manually controlling the opening and closing of the PE pipeline. By rotating the valve handle 2, the valve core inside the valve can be rotated, thereby changing the opening and closing state of the pipeline channel, allowing operators to adjust the flow of the medium in the PE pipeline as needed.

[0020] The connecting component 3 includes a short pipe sleeve 301, a rubber embedded ring 302, an internal hexagonal thread limit head 303, a first toothed curved surface clamp 304, a rubber bending pad 305, and a second toothed curved surface clamp 306. It is assembled at both ends of the PE pipe valve body 1 and is the key component for realizing the detachable connection between the PE pipe and the valve body 1. Through the synergistic effect of each sub-component, the firmness and sealing of the connection between the PE pipe and the valve are ensured, while simplifying the installation process.

[0021] The short sleeve 301 is integrally formed with both ends of the PE pipe valve body 1, providing space for the insertion of the PE pipe. It also serves as the mounting carrier for the rubber embedded ring 302, the internal hexagonal thread limit head 303, and the rubber bending pad 305, defining the installation position of each component and ensuring that the sub-components of the connecting assembly 3 are assembled in an orderly manner, laying a structural foundation for the subsequent fixing of the PE pipe.

[0022] The rubber-embedded circular ring 302 is bonded and fixed inside the short sleeve 301 and close to one end of the PE pipe valve body 1. The multiple annular grooves evenly distributed on its inner side increase the contact area and friction between the PE pipe and the outer wall of the PE pipe when the PE pipe is inserted into the short sleeve 301 and abuts against the component. On the one hand, it limits the depth of the PE pipe inserted into the short sleeve 301 to ensure accurate pipe installation. On the other hand, the elasticity of the rubber material and the annular groove structure enhance the sealing between the PE pipe and the short sleeve 301 to prevent leakage of the medium inside the pipe. The internal hexagonal threaded limiting head 303 is rotatably mounted in the threaded through hole on the bottom surface of the short pipe sleeve 301, and has a through hole at its lower end for the flat limiting long pin 4 to pass through. During installation, rotating this component with a hexagonal wrench can move the first toothed curved surface clamp 304 up and down, thereby squeezing and fixing the PE pipe. After installation, the flat limiting long pin 4, inserted into its through hole, can prevent itself from rotating, ensuring the stability of the PE pipe's fixed state. It is the core component in the connecting assembly 3 for adjusting and locking the fixing force of the PE pipe. The first-tooth curved clamping plate 304 is fitted onto the clamping head at the upper end of the internal hexagonal threaded limiting head 303. Its material hardness is higher than that of the PE pipe material. When the internal hexagonal threaded limiting head 303 rotates and moves upwards, the tips of its clamping teeth can press into the surface of the PE pipe. The higher hardness enhances the gripping force on the PE pipe, preventing displacement during use. Simultaneously, the curved structure provides a higher degree of contact with the outer wall of the PE pipe, ensuring even pressure distribution during fixing and preventing excessive local pressure from damaging the pipe. The rubber bending pad 305 is bonded and fixed in the internal groove of the short pipe sleeve 301, and is located between the short pipe sleeve 301 and the second toothed curved surface clamp 306, corresponding vertically to the first toothed curved surface clamp 304 below, forming a clamping space for the PE pipe. When the first toothed curved surface clamp 304 presses against the PE pipe, the PE pipe will push the second toothed curved surface clamp 306 upward, thereby causing the component to be squeezed and deformed. On the one hand, it can transmit the squeezing force back to the second toothed curved surface clamp 306 through its own elastic deformation, forcing the second toothed curved surface clamp 306 to fit tightly against the surface of the PE pipe. On the other hand, the rubber material can prevent the second toothed curved surface clamp 306 from making direct hard contact with the short pipe sleeve 301, reducing wear between the two during the force process. At the same time, the elastic buffer weakens the impact of the clamping force on the PE pipe, indirectly protecting the surface of the PE pipe from excessive squeezing damage.

[0023] The second-type toothed curved surface clamp 306 is bonded and fixed to the bottom surface of the rubber bending pad 305, and its material hardness is higher than that of the PE pipe material. Used in conjunction with the first-type toothed curved surface clamp 304, when the first-type clamp 304 presses against the PE pipe, the second-type toothed curved surface clamp 306, under the squeezing action of the rubber bending pad 305, also adheres tightly to the surface of the PE pipe. Its toothed tips, together with the toothed tips of the first-type clamp 304, are pressed into the surface of the PE pipe, forming a bidirectional fixation from both top and bottom, significantly improving the stability of the fixation and preventing the PE pipe from loosening or falling off under stress.

[0024] The flat limiting pin 4 is detachably assembled between the internal hexagonal thread limiting heads 303 of the connecting assembly 3, passing through the through hole at the lower end of the internal hexagonal thread limiting head 303. After the PE pipe is fixed, it is inserted into the through hole of the two internal hexagonal thread limiting heads 303, and the front end is bent with pliers or other tools to lock the internal hexagonal thread limiting head 303, preventing it from rotating due to vibration, medium pressure, or other factors during use. This ensures that the fixing state of the connecting assembly 3 for the PE pipe remains stable, and its detachable design also facilitates the subsequent disassembly and maintenance of the PE pipe.

[0025] The operation procedure of this utility model is as follows: When inserting the PE pipe, align the PE pipe to be connected with the openings of the short sleeves 301 at both ends of the valve body, slowly insert it into the short sleeves 301, and continue to push it until the end of the PE pipe is completely in contact with the rubber embedded ring 302 inside the short sleeves 301, and then stop the insertion operation.

[0026] When disassembling the flat limiting pin 4, observe the through hole at the lower end of the internal hexagon thread limiting head 303, pull out the flat limiting pin 4 that passes through the through hole, and release the rotation lock on the internal hexagon thread limiting head 303. When fixing the pipe by rotating the internal hexagonal threaded limit head 303, select a matching hexagonal wrench and insert the wrench head into the internal hexagonal groove of the internal hexagonal threaded limit head 303. Rotate the hexagonal wrench clockwise to rotate the internal hexagonal threaded limit head 303. As the internal hexagonal threaded limit head 303 rotates, the first toothed curved surface clamp 304 connected to its upper end will gradually move upward until the tips of the teeth of the first toothed curved surface clamp 304 press into the surface of the PE pipe, and the hexagonal wrench can no longer be rotated, so stop the rotation operation. At this time, under the compression of the first toothed curved surface clamp 304, the PE pipe pushes the second toothed curved surface clamp 306 upward, causing the rubber bending pad 305 to be compressed and deformed. Under the reaction force of the rubber bending pad 305, the second toothed curved surface clamp 306 is tightly attached to the surface of the PE pipe, forming a bidirectional clamping fixation.

[0027] When reinstalling the locking pin 4, take the previously removed flat limiting pin 4 and insert it into the through hole at the lower end of the internal hexagon thread limiting head 303, ensuring that the pin completely penetrates the through holes of the two opposing internal hexagon thread limiting heads 303. Then, use pliers to clamp the front end of the flat limiting pin 4 protruding from the through hole and bend it to one side to relock the internal hexagon thread limiting head 303 and prevent it from rotating during subsequent use.

[0028] When operating the valve for on / off control, to adjust the flow of medium in the PE pipeline, hold the valve handle 2, which is installed in the middle of the valve body 1, and rotate the valve handle 2 clockwise or counterclockwise. Rotating the valve handle 2 causes the valve core inside the valve to rotate, changing the on / off state of the pipeline and thus opening or closing the PE pipeline. Rotating the valve handle 2 to the corresponding position according to actual needs will control the flow of the medium.
