Description
A low-temperature water pipeline exhaust device Technical Field
[0001] This utility model relates to the field of pipeline venting technology, specifically to a low-temperature water pipeline venting device. Background Technology
[0002] Low-temperature water pipes are widely used in modern industrial and civil water supply and drainage systems, but their operation often faces numerous challenges. On the one hand, in low-temperature environments, dissolved gases in the water are prone to precipitate and accumulate at the top of the pipe, forming air pockets that obstruct water flow, increase resistance, reduce system efficiency, and may also cause pipe vibration and noise, affecting system stability and service life. On the other hand, minerals in the water are more likely to precipitate and deposit at low temperatures, forming blockage crystals that reduce the pipe's flow area, leading to localized water temperature increases, corrosion of the pipe's inner wall, and reduced pipe strength and durability. Although some venting devices and cleaning methods exist in existing technologies, traditional venting valves have limited venting effectiveness and are difficult to control precisely; chemical cleaning easily corrodes pipes and subsequent wastewater treatment is costly; manual cleaning is time-consuming, labor-intensive, and requires system shutdown and pipe disassembly, severely impacting normal system operation. Summary of the Invention
[0003] This utility model proposes a low-temperature water pipeline exhaust device, which solves the problems of existing technologies where chemical cleaning easily corrodes pipelines and subsequent wastewater treatment costs are high, while manual cleaning is time-consuming, labor-intensive, and requires shutdown and disassembly of the pipeline.
[0004] The technical solution of this utility model is as follows:
[0005] A low-temperature water pipe venting device includes a mounting base for mounting on a water pipe. The mounting base has a mounting cavity that is connected to the water pipe. A connecting pipe and a vent pipe are disposed within the mounting cavity. An opening and closing component is provided between the connecting pipe and the vent pipe to control the connection or disconnection of the connecting pipe and the vent pipe. When the connecting pipe and the vent pipe are not connected, one end of the vent pipe is connected to the mounting cavity, and the other end of the vent pipe is connected to the outside. A mounting cap for sealing the mounting cavity is threaded onto the mounting base. The device also includes a cleaning component disposed on the vent pipe for cleaning blockages and crystals within the vent pipe.
[0006] As a further technical solution, both the connecting pipe and the vent pipe have abutting ends. After the abutting ends of the connecting pipe and the vent pipe abut against each other, the connecting pipe and the vent pipe are connected. The opening and closing assembly includes a float that is movably disposed in the installation cavity. One end of the connecting pipe is disposed on the float. After the float moves in the installation cavity, it is used to drive the abutting ends of the connecting pipe and the vent pipe to disengage. It also includes a first elastic member with one end disposed on the connecting pipe and the other end disposed on the vent pipe. The first elastic member is used to provide the force for the abutting ends of the connecting pipe and the vent pipe to abut against each other.
[0007] As a further technical solution, the cleaning component includes a cleaning seat fitted inside the installation cavity and on the vent pipe. The cleaning seat has guide slopes on both sides of the vent pipe, and the guide slopes are connected to the inside of the vent pipe. A top block is slidably arranged on the guide slope. After the top block slides along the guide slope, it is used to slide into or out of the vent pipe. After the top block slides in the vent pipe, it is used to clean the blockage crystals in the vent pipe.
[0008] As a further technical solution, the cleaning component also includes a force-receiving plate that is slidably sleeved on the vent pipe. The force-receiving plate is connected to the top block. After the force-receiving plate slides, it is used to drive the top block to slide inside the vent pipe. It also includes a second elastic member with one end set on the force-receiving plate and the other end set on the vent pipe. The second elastic member is used to provide a force for the force-receiving plate to approach the connecting pipe.
[0009] As a further technical solution, a filter plate is installed on the mounting base inside the mounting cavity.
[0010] As a further technical solution, the inner wall of the mounting base has a first sliding groove, and the filter plate has a protrusion for sliding within the first sliding groove.
[0011] As a further technical solution, the bottom of the mounting base has external threads, and the mounting base threads are set on the water pipe.
[0012] As a further technical solution, the outer side of the mounting cap has an external hexagonal thread.
[0013] The working principle and beneficial effects of this utility model are as follows:
[0014] In this invention, the device includes a mounting base fixed to a water pipe, forming an internal mounting cavity that communicates with the inside of the water pipe. Within the mounting cavity, a connecting pipe and a vent pipe are arranged in parallel, connected by an opening / closing assembly for precisely controlling the connection or disconnection of the two vent pipes. When venting is required, the opening / closing assembly is opened, disconnecting the connecting pipe and the vent pipe, allowing gas to escape to the outside through the other end of the vent pipe. One end of the vent pipe communicates with the mounting cavity, while the other end extends to the outside of the mounting base and communicates with the outside atmosphere through a sealed interface. A threaded mounting cap is attached to the mounting base to seal the mounting cavity, preventing water leakage and the entry of external impurities. Furthermore, a cleaning assembly is installed on the vent pipe to periodically clean any blockages and crystals within the vent pipe, ensuring unobstructed venting. This design effectively solves the problems of gas accumulation and blockage / crystallization in low-temperature water pipelines, improving the operational efficiency and stability of the pipeline system.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0022] Example
[0023] As shown in Figures 1-4, a low-temperature water pipe venting device includes a mounting base 1, which is used to install on a water pipe. The mounting base 1 has a mounting cavity 2, which is connected to the water pipe. A connecting pipe and an vent pipe are installed inside the mounting cavity 2. An opening and closing component 5 is provided between the connecting pipe and the vent pipe. The opening and closing component 5 is used to control the connection or disconnection of the connecting pipe and the vent pipe. When the connecting pipe and the vent pipe are not connected, one end of the vent pipe is connected to the mounting cavity 2, and the other end of the vent pipe is connected to the outside. A mounting cap 6 for sealing the mounting cavity 2 is threaded on the mounting base 1. The device also includes a cleaning component 7 installed on the vent pipe, which is used to clean the blockage crystals in the vent pipe.
[0024] In this embodiment, the device includes a mounting base 1, which is fixed to the water pipe and forms a mounting cavity 2 inside, which communicates with the inside of the water pipe. A connecting pipe and a vent pipe are arranged in parallel within the mounting cavity 2, connected by an opening / closing component 5. This component 5 precisely controls the connection or disconnection of the two vent pipes. When venting is required, the opening / closing component 5 is opened, disconnecting the connecting pipe and the vent pipe, allowing gas to escape to the outside through the other end of the vent pipe. One end of the vent pipe communicates with the mounting cavity 2, and the other end extends to the outside of the mounting base 1, communicating with the outside atmosphere through a sealed interface. A mounting cap 6 is threaded onto the mounting base 1 to seal the mounting cavity 2, preventing water leakage and the entry of external impurities. Furthermore, a cleaning component 7 is provided on the vent pipe, used to periodically clean blockages and crystals within the vent pipe, ensuring unobstructed venting. Through this design, the device effectively solves the problems of gas accumulation and blockage crystals in low-temperature water pipes, improving the operating efficiency and stability of the pipeline system.
[0025] Furthermore, both the connecting pipe and the vent pipe have abutting ends 8. After the abutting ends 8 of the connecting pipe and the vent pipe abut against each other, the connecting pipe and the vent pipe are connected. The opening and closing assembly 5 includes a float 9 movably disposed in the mounting cavity 2. One end of the connecting pipe is disposed on the float 9. After the float 9 moves in the mounting cavity 2, it is used to drive the abutting ends 8 of the connecting pipe and the vent pipe to disengage. It also includes a first elastic member 10 with one end disposed on the connecting pipe and the other end disposed on the vent pipe. The first elastic member 10 is used to provide the force for the abutting ends 8 of the connecting pipe and the vent pipe to abut against each other.
[0026] In this embodiment, a connecting pipe and an exhaust pipe are provided within the mounting cavity 2, both having abutting ends 8. When the abutting ends 8 of the connecting pipe and the exhaust pipe disengage, gas can enter the exhaust pipe and be discharged. The opening and closing assembly 5 includes a float 9 movably disposed within the mounting cavity 2, with one end of the connecting pipe mounted on the float 9. When the water level in the pipe changes, the float 9 moves up and down accordingly, thereby causing the abutting ends 8 of the connecting pipe and the exhaust pipe to disengage or engage. Furthermore, the device also includes a first elastic element 10, with one end mounted on the connecting pipe and the other end mounted on the exhaust pipe. This elastic element provides the force for the abutting ends 8 of the connecting pipe and the exhaust pipe to engage with each other, ensuring a tight connection when the float 9 is not in motion. This design utilizes water level changes to automatically control the venting process, while the elastic element ensures the reliability of the connection, effectively solving the problem of gas accumulation in low-temperature water pipes.
[0027] Furthermore, the cleaning component 7 includes a cleaning seat 11 fitted inside the installation cavity 2 and fitted onto the vent pipe. The cleaning seat 11 has guide slopes 12 on both sides of the vent pipe, and the guide slopes 12 are connected to the inside of the vent pipe. A top block 13 is slidably disposed on the guide slope 12. After the top block 13 slides along the guide slope 12, it is used to slide into or out of the vent pipe. After the top block 13 slides in the vent pipe, it is used to clean the blockage crystals in the vent pipe.
[0028] In this embodiment, the cleaning component 7 includes a cleaning seat 11, which is fitted onto the vent pipe within the mounting cavity 2. The cleaning seat 11 has a unique structural design, with guide ramps 12 on both sides of the vent pipe, these guide ramps 12 communicating with the interior of the vent pipe. A top block 13 is slidably mounted on the guide ramp 12, allowing it to slide flexibly into or out of the vent pipe as it slides along the guide ramp 12. Once the top block 13 enters the vent pipe and slides along its inner wall, it efficiently clears blockages and crystals within the vent pipe, ensuring the exhaust channel remains unobstructed. This cleaning method is not only simple to operate but also highly effective, significantly improving the reliability and practicality of the low-temperature water pipe venting device.
[0029] Furthermore, the cleaning assembly 7 also includes a force-receiving plate 14 slidably sleeved on the air outlet pipe. The force-receiving plate 14 is connected to the top block 13. After the force-receiving plate 14 slides, it is used to drive the top block 13 to slide inside the air outlet pipe. It also includes a second elastic member 19 with one end set on the force-receiving plate 14 and the other end set on the air outlet pipe. The second elastic member 19 is used to provide a force for the force-receiving plate 14 to approach the connecting pipe.
[0030] In this embodiment, the cleaning component 7 includes a force-receiving plate 14 slidably sleeved on the vent pipe, and the force-receiving plate 14 is connected to the top block 13. When the force-receiving plate 14 slides along the vent pipe, it can drive the top block 13 to slide inside the vent pipe, thereby cleaning the inner wall of the vent pipe. In addition, the device also includes a second elastic member 19, one end of which is disposed on the force-receiving plate 14 and the other end of which is disposed on the vent pipe. The function of the second elastic member 19 is to provide a force to bring the force-receiving plate 14 close to the connecting pipe, ensuring that the top block 13 can automatically reset and remain at the entrance of the vent pipe when no external force is applied, ready for cleaning operation at any time. Furthermore, the force-bearing plate 14 is sealed and slidably mounted on the air outlet pipe. Because the force-bearing plate 14 and the air outlet pipe are sealed and slidably mounted, the air pressure on the other side of the force-bearing plate 14 is constant. When the air pressure in the installation cavity 2 increases, it will push the force-bearing plate 14 to drive the top block 13 to slide and push out the crystals located in the air outlet pipe. This design not only improves the cleaning efficiency, but also reduces manual intervention through the automatic reset function of the elastic element, thereby enhancing the reliability and service life of the device.
[0031] Furthermore, a filter plate 15 is provided on the mounting base 1 within the mounting cavity 2.
[0032] In this embodiment, a filter plate 15 is added to the mounting base 1 of the low-temperature water pipeline exhaust device inside the mounting cavity 2. The filter plate 15 is made of stainless steel with a porous material and a pore size of 0.5 mm. It effectively intercepts impurity particles in the water flow, prevents them from entering the mounting cavity 2 and the exhaust pipe, reduces the generation of blockage and crystallization, and at the same time ensures the water quality of the entire pipeline system, improving the overall performance and service life of the device.
[0033] Furthermore, the inner wall of the mounting base 1 has a first groove 16, and the filter plate 15 has a protrusion 17, which is used to slide within the first groove 16.
[0034] In this embodiment, the inner wall of the mounting base 1 is provided with a first sliding groove 16, and the edge of the filter plate 15 is provided with a matching protrusion 17. Through the cooperation of the protrusion 17 and the first sliding groove 16, the filter plate 15 can be stably slidably installed on the inner wall of the mounting base 1, which facilitates quick disassembly and cleaning, and further improves the ease of maintenance of the device.
[0035] Furthermore, the bottom of the mounting base 1 has external threads, and the threads of the mounting base 1 are set on the water pipe.
[0036] In this embodiment, the bottom of the mounting base 1 is designed with an external thread. By cooperating with the internal thread on the water pipe, the mounting base 1 can be securely threaded onto the water pipe, ensuring a tight connection and sealing between the venting device and the water pipe. At the same time, it is easy to install and disassemble, improving the practicality and maintenance convenience of the device.
[0037] Furthermore, the outer side of the mounting cap 6 has an external hexagonal thread 18.
[0038] In this embodiment, the mounting cap 6 is designed with an external hexagonal thread 18 on its outer side. By cooperating with the internal thread on the mounting base 1, the mounting cap 6 can be firmly screwed onto the mounting base 1 to achieve a seal on the mounting cavity 2. At the same time, the external hexagonal structure facilitates tightening and disassembly operations using tools, further improving the installation and maintenance efficiency of the device.
[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
