Description

Technical Field

[0001] The utility model relates to the technical field of installing a switching valve, in particular to a switching valve which is easy to install. Background Art

[0002] An easy-to-install switching valve is a valve device with an optimized design that can reduce complex steps, installation difficulty and time costs during the installation process. It usually has a simple structure, clear installation instructions and good compatibility with common installation environments and interfaces. It is used to switch between different fluid pipelines, such as switching between cold water and hot water pipelines, to meet different usage requirements.

[0003] Most of the existing switching valves and water pipes are fixedly connected by threads, which is not convenient for installation. When the switching valve is blocked or damaged, it is troublesome for the staff to repair and disassemble it. Moreover, after the switching valve is used for a long time, the connection between the switching valve and the water pipe is easily corroded by the water inside the water pipe, which causes the connection between the switching valve and the water pipe to rust or even damage, thereby affecting the normal use of the switching valve.

[0004] The existing patent (publication number: CN219639584U) discloses a switching valve that is easy to install, including a switching valve body, a water pipe and a plurality of connecting ports opened on the switching valve body. A limiting device is arranged on the switching valve body near the connecting port. This switching valve that is easy to install, by pressing the rotating plate, the limiting block is lifted up, and the connecting pipe is inserted into the connecting port. After releasing the hand, the limiting block is engaged with the limiting groove, and the water pipe can be fixedly connected to the switching valve. When the staff needs to inspect or replace the switching valve, they only need to press the rotating plate to remove the water pipe from the inside of the switching valve body, thereby making the installation and disassembly of the switching valve more convenient.

[0005] In view of the above problems, existing patents have provided solutions, but most of the existing switching valves use complex installation structures for installation and connection. The complex installation process will consume a lot of time, resulting in delays in project progress and difficulties in subsequent maintenance and repair work. In addition, during the installation process, impurities can easily cause blockage inside the switching valve during use, or the corrosive components of the fluid can cause corrosion to the valve body.

[0006] To this end, a switching valve that is easy to install is proposed. Utility Model Content

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-6 , the utility model provides a technical solution:

[0029] A switching valve that is easy to install, comprising a switching valve structure 1 and a connecting pipe 5, wherein a sealing ring 6 is clamped inside the switching valve structure 1, and the surface of the sealing ring 6 is clamped with the inner wall of the connecting pipe 5, and a first limiting frame 7 is clamped on the surface of the switching valve structure 1, and a limiting block 8 is arranged on the front side of the first limiting frame 7, and a second limiting frame 9 is arranged on the top of the first limiting frame 7, and a limiting plate 10 is bolted to the front side of the second limiting frame 9, and a quick-installing mechanism 3 is connected to the inner thread of the limiting block 8, and the bottom of the quick-installing mechanism 3 is in close contact with the top of the limiting plate 10, and a filtering mechanism 2 is clamped on the inner wall of the switching valve structure 1, and a coarse filtering component 4 is clamped inside the filtering mechanism 2;

[0030] The quick-loading mechanism 3 includes a rotating rod 301, a rotating plate 302 and a threaded rod 303. The top of the threaded rod 303 is bolted to the bottom of the rotating plate 302, the bottom of the rotating rod 301 is bolted to the top of the rotating plate 302, the surface of the threaded rod 303 is threadedly connected to the inner wall of the limit block 8, and the bottom of the rotating plate 302 is in close contact with the top of the limit plate 10.

[0031] In this embodiment: by setting up the quick-installation mechanism 3, when in use, the rotating rod 301, the rotating plate 302 and the threaded rod 303 in the quick-installation mechanism 3 are used in coordination with the first limiting frame 7, the second limiting frame 9, the limiting block 8 and the limiting plate 10, so that the installation process of the switching valve structure 1 becomes extremely simple and quick. The setting of the rotating rod 301 is convenient for the operator to rotate manually, and the installation can be completed without complicated tools. The cooperation of the rotating plate 302 and the threaded rod 303 can stably press the limiting plate 10, ensuring the firm connection between the first limiting frame 7 and the second limiting frame 9, thereby greatly improving the efficiency and stability of the installation. When the industrial pipeline system is urgently repaired or the switching valve structure 1 is replaced, this quick installation feature can significantly shorten the downtime and reduce production losses. At the same time, since the installation process is simple and easy to understand, the requirements for the technical level of the installers are lowered, and the risk of failure caused by installation errors is reduced. By setting the filter mechanism 2 and the coarse filter component 4, the filter mechanism 2 can effectively intercept impurities and particulate matter in the fluid through the coordinated use of the filter mechanism 2 and the coarse filter component 4 during use, and the coarse filter component 4 further enhances the filtering effect, preventing larger particles from entering the switching valve structure 1, thereby reducing the blockage and damage caused by the accumulation of impurities in the switching valve structure 1. In addition, the card connection setting of the filter mechanism 2 and the coarse filter component 4 makes their installation and replacement very convenient, easy to maintain and clean regularly, and maintains good filtering performance, which helps to reduce maintenance costs and ensure that the switching valve structure 1 can work stably under various working conditions.

[0032] Specifically, Figure 3 As shown, the filter mechanism 2 includes a filter cartridge 201, a filter frame 202 and a filter screen 203. The surface of the filter screen 203 is fixedly connected to the interior of the filter frame, the surface of the filter frame 202 is fixedly connected to the inner wall of the filter cartridge 201, and the surface of the filter cartridge 201 is clamped to the interior of the switching valve structure 1.

[0033] Specifically, Figure 3 As shown, the inner wall of the filter cartridge 201 is fixedly connected to a limiting ring 11 , and the left side of the limiting ring 11 is in contact with the right side of the coarse filter assembly 4 .

[0034] Specifically, Figure 3 As shown, the coarse filter assembly 4 includes a coarse filter frame 401 and a pull rod 402, the surface of the pull rod 402 is bolted to the inside of the coarse filter frame 401, the surface of the coarse filter frame 401 is clamped to the inner wall of the filter cartridge 201, and the right side of the coarse filter frame 401 is in contact with the left side of the limit ring 11.

[0035] In this embodiment: through the cooperation of the filter cartridge 201, the filter frame 202 and the filter screen 203 in the filter mechanism 2, the filter screen 203 can effectively intercept tiny impurities in the fluid, thereby improving the filtration accuracy. The limit ring 11 on the inner wall of the filter cartridge 201 plays a role in positioning and supporting the coarse filter component 4, which can ensure that the coarse filter component 4 is installed in the correct position to prevent it from shifting under the impact of the fluid, thereby ensuring the stability of the filtering effect. The coarse filter frame 401 and the pull rod 402 of the coarse filter component 4 are reasonably designed. The pull rod 402 facilitates the installation and disassembly of the coarse filter frame 401, making the replacement of the coarse filter component 4 simple and quick. The coarse filter frame 401 can intercept larger particles of impurities, reduce the burden of subsequent filtering components, and extend the service life of the entire filter mechanism 2. At the same time, the clamping method with the inner wall of the filter cartridge 201 is convenient for operation and improves maintenance efficiency.

[0036] Specifically, Figure 4 , Figure 5 As shown, a fixing plate 12 is bolted to the front side of the first limiting frame 7 , a rotating shaft 13 is rotatably connected inside the fixing plate 12 , and a side of the rotating shaft 13 close to the limiting block 8 is bolted to the limiting block 8 .

[0037] Specifically, Figure 5 As shown, a bearing 14 is fixedly connected to the surface of the rotating shaft 13 , and the surface of the bearing 14 is fixedly connected to the inner wall of the fixed plate 12 . The rotating shaft 13 is rotatably connected to the fixed plate 12 via the bearing 14 .

[0038] In this embodiment: the fixed plate 12 on the front side of the first limit frame 7 provides stable support for the rotating shaft 13, and the rotating shaft 13 is connected to the limit block 8, so that the limit block 8 can be flexibly rotated through the rotating shaft 13. During the installation process, the angle of the limit block 8 can be adjusted according to actual conditions, which is convenient for connection and fixation with other components, thereby improving the flexibility of installation. The setting of the bearing 14 reduces the friction force when the rotating shaft 13 rotates, making the rotation of the rotating shaft 13 smoother, which not only reduces the difficulty of operation, but also reduces the wear and energy loss caused by friction, thereby extending the service life of the rotating shaft 13 and facilitating user use.

[0039] Specifically, Figure 4 , Figure 6 As shown, a rotating assembly 15 is bolted to the rear side of the first limiting frame 7 , and a front side of the rotating assembly 15 is bolted to the rear side of the second limiting frame 9 .

[0040] Specifically, Figure 1 , Figure 2 As shown, a switch switching component 16 is disposed on the top of the switching valve structure 1 , and a flow monitoring component 17 is disposed on the top of the switching valve structure 1 .

[0041] In this embodiment: the second limit frame 9 is connected to the first limit frame 7 by a rotating component 15 on the rear side, so that the second limit frame 9 can rotate relative to the first limit frame 7. During the installation process, the rotating component 15 can adapt to different installation angles and space requirements, thereby improving the adaptability and convenience of the installation. The switch switching component 16 can conveniently perform switch operations on the switching valve structure 1, making the valve switching faster and more accurate, meeting the flow control requirements under different working conditions. The flow monitoring component 17 can monitor the flow of the fluid in the switching valve structure 1 in real time, providing users with accurate flow data, and helping to promptly discover and solve abnormal flow problems.

[0042] Working principle: During the use of the switching valve structure 1 and the connecting pipe 5, a quick-installation mechanism 3 is provided. When in use, the rotating rod 301, the rotating plate 302 and the threaded rod 303 in the quick-installation mechanism 3 are used in coordination with the first limit frame 7, the second limit frame 9, the limit block 8 and the limit plate 10, so that the installation process of the switching valve structure 1 becomes extremely simple and quick. The setting of the rotating rod 301 is convenient for the operator to rotate manually, and the installation can be completed without complicated tools. The cooperation of the rotating plate 302 and the threaded rod 303 can stably press the limit plate 10, ensuring a firm connection between the first limit frame 7 and the second limit frame 9, thereby greatly improving the efficiency and stability of the installation. When the switching valve structure 1 is urgently repaired or replaced in the industrial pipeline system, this quick installation feature can significantly shorten the downtime. The filter mechanism 2 and the coarse filter component 4 are arranged so that the impurities and particulates in the fluid are effectively intercepted, and the coarse filter component 4 further enhances the filtering effect and prevents larger particles from entering the interior of the switching valve structure 1, thereby reducing the blockage and damage caused by the accumulation of impurities in the switching valve structure 1. In addition, the clamping setting of the filter mechanism 2 and the coarse filter component 4 makes their installation and replacement very convenient, and is convenient for regular maintenance and cleaning, so as to maintain good filtering performance, which helps to reduce maintenance costs and ensure that the switching valve structure 1 can work stably under various working conditions.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
