Description

Technical Field

[0001] This utility model relates to the field of valve installation and sealing structure technology, and in particular to the valve installation and sealing structure for water supply and drainage pipes. Background Technology

[0002] In drainage systems, valves are key components for controlling water flow. They are used to regulate, guide, or prevent fluid flow. The valve installation and sealing structure ensures a reliable sealing connection between the valve and the pipeline and maintains good performance under complex operating conditions. They are mainly used in water supply and drainage pipeline networks inside and outside buildings to ensure the reliability of water flow control, or to regulate the flow of hot or cold water to ensure efficient pipeline operation. In industries such as chemical and pharmaceutical, they are used to transport various media to ensure the safety and stability of the production process.

[0003] During the process of regulating water flow through valves, the impact of water flow or vibrations caused by external vehicles can cause continuous disturbances to the pipeline structure. Due to the lack of effective shock absorption measures for the existing structure, multiple bolts are usually installed at the connection between the valve and the pipeline. These vibrations can easily cause the bolts connecting the valve and the pipeline to loosen, thereby affecting the sealing performance and valve stability. At the same time, the valve installation sealing structure generally suffers from insufficient freedom of movement and lacks sufficient offset adaptability. In winter and summer when the temperature changes greatly, the stress generated by the thermal expansion and contraction of the pipeline cannot be effectively released, which can easily damage the connection parts and affect the service life of the pipeline.

[0004] Therefore, the lack of effective shock absorption measures for the floating space in the aforementioned valve installation sealing structure can easily lead to loosening of the bolts connecting the valve and the pipeline, thereby affecting the sealing performance and valve stability. There is an urgent need to design a new type of valve installation sealing structure for water supply and drainage pipes. Utility Model Content

[0005] To overcome the common problem that valve installation sealing structures lack effective shock absorption measures for floating space, which can easily lead to loosening of bolts connecting valves and pipelines, thus affecting sealing performance and valve stability.

[0006] The technical solution of this utility model is as follows: a sealing structure for installing a water supply and drainage pipe valve, including a valve body mounting pipe; and a mounting plate disposed on the upper end face of the valve body mounting pipe, the mounting plate providing a fulcrum for valve installation, four fixing screw holes and a fixing groove provided on the upper end face of the mounting plate, the fixing groove providing installation space for the valve installation, a floating connection component disposed at each end of the valve body mounting pipe, an installation component disposed on the floating connection component, and a shock-absorbing component disposed on the outside of the valve body mounting pipe, the installation component being used to connect the valve body mounting pipe to an external drainage pipe, the floating connection component providing a floating effect at the connection between the valve body mounting pipe and the drainage pipe, and the shock-absorbing component providing a shock-absorbing effect at the connection between the valve body mounting pipe and the drainage pipe.

[0007] Preferably, the valve body mounting pipe is used to connect the valve to the pipeline structure to realize fluid on / off control. The mounting plate is fixedly set on the upper end face of the valve body mounting pipe, providing a stable mounting support for the valve. The fixing screw holes on it are used to cooperate with the bottom flange of the valve to achieve a tight connection. The fixing groove provides positioning and installation space for the valve, enhancing installation stability. The floating connection assembly includes bellows, which are respectively set at both ends of the valve body mounting pipe. It has good angular expansion and contraction capacity and can effectively absorb displacement stress caused by installation errors, thermal expansion and contraction, or foundation settlement, improving connection flexibility and adaptability. The mounting assembly consists of a flange and bolt holes, which are installed on the outer end of the bellows and provide a standard flange interface for easy sealing connection with external drainage pipes, ensuring the overall sealing performance of the system. The shock absorption assembly includes a fixing ring, a damper, and a spring, which are set on the outside of the valve body mounting pipe. The fixing ring provides a mounting base for the damper and spring. The damper and spring work together to absorb vibration and impact from the pipeline system and prevent sealing failure or structural fatigue caused by vibration.

[0008] Preferably, the floating connection assembly includes bellows connected to both ends of the valve body mounting pipe, the bellows being angularly expandable and contractible to reduce stress changes caused by errors in the mounting assembly.

[0009] Preferably, the mounting components include a flange installed at the end of the bellows away from the valve body mounting pipe, and bolt holes distributed in a ring on the surface of the flange.

[0010] Preferably, the flange provides a flat connection surface for connecting to an external drain pipe, and the bolt holes are used to connect bolts and nuts to form a sealed connection.

[0011] Preferably, the damping assembly includes a fixing ring disposed on the outside of the valve body mounting pipe, a damper annularly disposed on the surface of the fixing ring, and a spring movably sleeved on the surface of the damper.

[0012] Preferably, the retaining ring provides the mounting point and space for the damper, which absorbs vibration, impact force and displacement, and the spring is used to restore the damper to its original shape after the vibration disappears.

[0013] Preferably, a connecting cover is installed on the side of the flange near the valve body mounting pipe. The end of the spring away from the valve body mounting pipe is connected inside the connecting cover. An internal universal joint is installed inside the connecting cover. The output end of the damper is connected to the surface of the internal universal joint. The connecting cover provides a connection point for the spring and provides installation space for the internal universal joint. The internal universal joint, as a flexible connecting element, works in conjunction with the damper and the spring to achieve angle compensation and vibration reduction functions.

[0014] The beneficial effects of this utility model are: 1. By setting up shock-absorbing components, including fixed rings, dampers and springs, and combining them with built-in universal joints, good vibration reduction and buffering functions are achieved, effectively absorbing vibration and impact forces during pipeline operation, preventing the sealing structure from failing due to external forces, improving the stability of valve connections and sealing reliability, and extending service life. 2. The floating connection assembly adopts a bellows structure, which has good angular expansion and contraction capacity, and can adapt to the displacement changes caused by installation errors and thermal expansion and contraction of pipelines. This allows the valve to maintain a stable connection under complex working conditions, improves installation tolerance and construction efficiency, and ensures the long-term safe operation of the valve.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5This utility model provides an embodiment of a sealing structure for installing a valve in a water supply and drainage pipe, including a valve body mounting pipe 1; and a mounting plate 2 disposed on the upper end face of the valve body mounting pipe 1. The mounting plate 2 provides a fulcrum for valve installation. Four fixing screw holes 4 are formed on the upper end face of the mounting plate 2, and a fixing groove 3 is formed on the upper end face of the mounting plate 2, providing installation space for the valve. A floating connection assembly is disposed at each end of the valve body mounting pipe 1, and an installation assembly is disposed on the floating connection assembly. A shock-absorbing assembly is disposed on the outside of the valve body mounting pipe 1. The installation assembly is used to connect the valve body mounting pipe 1 to an external drainage pipe. The floating connection assembly provides a floating effect at the connection between the valve body mounting pipe 1 and the drainage pipe, and the shock-absorbing assembly provides a shock-absorbing effect at the connection between the valve body mounting pipe 1 and the drainage pipe. This embodiment requires the use of a drainage pipe and a valve. The valve body mounting pipe 1 is used to connect the valve and the pipe structure to achieve fluid flow control. The mounting plate 2 is fixedly disposed on the valve body mounting pipe. The upper end face of pipe 1 provides a stable mounting point for the valve; the fixing screw hole 4 on it is used to cooperate with the bottom flange of the valve to achieve a tight connection; the fixing groove 3 provides positioning and installation space for the valve, enhancing installation stability. The floating connection assembly includes bellows 6, which are respectively set at both ends of the valve body mounting pipe 1. It has good angular expansion and contraction capacity and can effectively absorb displacement stress caused by installation errors, thermal expansion and contraction or foundation settlement, improving connection flexibility and adaptability. The mounting assembly consists of flange 7 and bolt holes 8, which are installed on the outer end of bellows 6 and provide a standard flange interface for easy sealing connection with external drainage pipes, ensuring the overall sealing performance of the system. The shock absorption assembly includes a fixing ring 5, a damper 9 and a spring 10, which are set on the outside of the valve body mounting pipe 1. The fixing ring 5 provides a mounting base for the damper 9 and the spring 10. The damper 9 and the spring 10 work together to absorb vibration and impact from the pipeline system and prevent sealing failure or structural fatigue caused by vibration.

[0019] Please see Figures 1-4In this embodiment, the floating connection assembly includes bellows 6 connected to both ends of the valve body mounting pipe 1. The bellows 6 can extend and retract angularly, reducing stress changes caused by installation errors (the bellows 6 can absorb stress changes caused by installation errors, thermal expansion and contraction, or foundation settlement, providing a flexible connection, avoiding deformation or leakage of the flange sealing surface caused by rigid connection, protecting the valve and pipeline interface, and improving the adaptability of the pipeline structure). The installation assembly includes a flange 7 installed at the end of the bellows 6 away from the valve body mounting pipe 1, and bolt holes 8 distributed in a ring on the surface of the flange 7 (the flange 7 provides a flat and stable sealing contact surface, facilitating the installation of sealing gaskets, ensuring good sealing performance of the connection, and supporting standardized installation methods). The flange 7 provides a flat connection surface for connection with the external drain pipe. The bolt holes 8 are used to connect bolts and nuts to form a sealed connection (the bolt holes 8 realize a detachable fastening connection between flanges, evenly distribute the force, ensure uniform pressure on the sealing gasket, prevent leakage, support multiple standard bolt specifications, and adapt to different engineering needs).

[0020] Please see Figures 1-5 In this embodiment, the vibration damping assembly includes a fixing ring 5 disposed on the outside of the valve body mounting pipe 1, a damper 9 annularly disposed on the surface of the fixing ring 5, and a spring 10 movably sleeved on the surface of the damper 9 (the fixing ring 5 provides the mounting point and installation space for the damper 9, ensuring that the damper 9 is evenly distributed around the valve body to achieve force balance). The fixing ring 5 provides the mounting point and installation space for the damper 9, which absorbs vibration, impact force, and displacement. The spring 10 is used to restore the damper 9 to its original state after the vibration disappears (the damper 9 reduces structural disturbances caused by water flow impact, equipment vibration, or external vibration, preventing vibration from being directly transmitted to the connection between the valve and the flange 7, improving the operational stability and sealing reliability of the structure; the spring 10 restores the damper 9 to its original position after the vibration or impact disappears, working in synergy with the damper 9 to form a damping and elastic vibration reduction structure). The flange 7 is close to the valve body. A connecting cover 11 is installed on one side of the mounting pipe 1. The end of the spring 10 away from the valve body mounting pipe 1 is connected inside the connecting cover 11. An internal universal joint 12 is installed inside the connecting cover 11. The output end of the damper 9 is connected to the surface of the internal universal joint 12. The connecting cover 11 provides a connection point for the spring 10 and provides installation space for the internal universal joint 12. The internal universal joint 12, as a flexible connecting element, works in conjunction with the damper 9 and the spring 10 to achieve angle compensation and vibration reduction functions. (The connecting cover 11 provides a connection end point for the spring 10 to form a complete vibration reduction circuit and provides installation space for the internal universal joint 12 to achieve structural integration. The internal universal joint 12, as a flexible connecting element, allows the connecting structure to deflect freely in multiple directions, achieving angle compensation functions, adapting to small offsets of the flange connection surface, and working in conjunction with the damper 9 and the spring 10 to improve the overall vibration reduction effect and structural adaptability.)

[0021] During operation, the valve body mounting pipe 1 serves as the main structure, connecting the valve to the external drainage pipe for fluid flow control. The mounting plate 2 is positioned on the upper surface of the valve body mounting pipe 1, providing a mounting support for the valve. The fixing groove 3 provides positioning space for the valve. Fixing bolt holes 4 are used for connection to the valve flange, enhancing installation stability. Both ends of the valve body mounting pipe 1 are equipped with floating connection components, bellows 6, which possess excellent angular expansion and contraction capabilities, absorbing stress changes caused by installation errors, thermal expansion and contraction, or foundation settlement. This prevents deformation of the sealing surface due to rigid connections and improves connection flexibility. The end of the bellows 6 furthest from the valve body mounting pipe 1 connects to a flange 7. The flange 7 has annularly distributed bolt holes 8 for sealing connection to the external drainage pipe using bolts and nuts, ensuring uniform stress on the connection surface and preventing... To prevent leakage, a shock-absorbing assembly is provided on the outside of the valve body mounting pipe 1, including a fixing ring 5, a damper 9, and a spring 10. The fixing ring 5 provides the mounting point and space for the damper 9, allowing it to be evenly distributed around the valve body. The damper 9 absorbs vibration and impact from the pipeline system, preventing vibration from being transmitted to the connection parts. The spring 10 restores the damper 9 to its original position after the vibration disappears, achieving elastic reset. A connecting cover 11 is installed on the side of the flange 7 near the valve body mounting pipe 1. The end of the spring 10 away from the valve body is connected to the inside of the connecting cover 11. The connecting cover 11 also has a built-in universal joint 12 inside, and the output end of the damper 9 is connected to its surface. The built-in universal joint 12, as a flexible connecting element, can achieve multi-directional deflection, compensate for angle deviation, and work together with the damper 9 and the spring 10 to improve the overall shock absorption effect and structural adaptability.

[0022] Through the above steps, by setting the fixed ring 5, damper 9, spring 10 and built-in universal joint 12, the vibration reduction and buffer function is realized, which effectively absorbs vibration and impact force, improves valve connection stability and sealing reliability, and extends service life. This solves the problem that common valve installation sealing structures lack effective floating space for vibration reduction measures, which can easily lead to loosening of bolts connecting valves and pipelines, thereby affecting sealing performance and valve stability.
