Description

Technical Field

[0001] This utility model relates to the field of hydraulic check valve technology, and in particular to a hydraulic check valve that prevents clogging. Background Technology

[0002] Check valves are commonly used in irrigation systems and are installed on pipelines. A check valve is a valve whose opening and closing element is a circular valve disc that relies on its own weight and the pressure of the medium to prevent backflow, thus serving the purpose of preventing water backflow. Publication number CN212616542U discloses a check valve for irrigation, which, through its design, can prevent water backflow in farmland and protect water sources from pollution. It includes a valve body, an inlet pipe, a drain pipe, and a partition. The left end of the valve body is connected to the right end of the inlet pipe, and the right end of the valve body is connected to the left end of the drain pipe. The partition is fixedly installed inside the inlet pipe. It also includes a cover plate, a mounting bracket, a spring, a limit plate, a connecting rod, a plug, two sets of fixing bolts, two sets of washers, a filter box, a cartridge box, and a mounting bracket. The top of the valve body has an opening, and the cover plate... The device is fitted into the opening, with the top of the mounting bracket and the bottom of the cover plate fixedly connected. The spring is located inside the mounting bracket, with its top and the bottom of the cover plate fixedly connected. The limiting plate is located inside the mounting bracket, with its top and the bottom of the spring fixedly connected. The connecting rod passes through the bottom of the mounting bracket, with its top and the bottom of the limiting plate fixedly connected. The bottom of the connecting rod is fixedly connected to the top of the plug, and the bottom of the plug can be inserted into the plug hole. In practical applications, the water transported in irrigation is usually drawn from ponds or rivers. River water often contains sludge and debris. The valve body of the check valve is relatively small, and small debris and sludge in the water can easily cause blockage of the check valve, affecting the drainage and irrigation of the pipeline and reducing the efficiency of irrigation. Improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a hydraulic check valve for preventing clogging, comprising a check valve body and an inlet, an outlet fixedly installed on the surface of the check valve body, an anti-clogging chamber placed between the check valve body and the inlet, a first fixing sleeve threadedly connected between the anti-clogging chamber and the check valve body, a second fixing sleeve threadedly connected between the inlet and the anti-clogging chamber, a first extension ring fixedly installed on the surface of the anti-clogging chamber, a second extension ring fixedly installed on the surface of the inlet, a filter assembly placed inside the anti-clogging chamber, a filter plate fixedly installed on the surface of the filter assembly, a leakage hole opened on the surface of the filter assembly, and a handle rotatably connected to the surface of the filter assembly.

[0005] Preferably, an activated carbon plate is fixedly installed inside the anti-clogging chamber, and the activated carbon plate is located directly behind the filter assembly. Here, the activated carbon plate can further adsorb impurities in the river water, thereby preventing finer impurities from entering the interior of the check valve body and causing damage to the internal parts of the check valve.

[0006] Preferably, both the first and second fixing sleeves slide on the surface of the anti-clogging chamber, and both surfaces of the first and second fixing sleeves are provided with anti-slip textures. These anti-slip textures increase the friction between the user's hand and the first and second fixing sleeves, thereby facilitating the user to unscrew the first and second fixing sleeves and remove the anti-clogging chamber for maintenance.

[0007] Preferably, the anti-clogging chamber is located between the inlet and the check valve body. Here, water enters from the inlet, passes through the anti-clogging chamber, enters the interior of the check valve body, and finally flows out from the outlet. The anti-clogging chamber filters the water flow before it enters the check valve body, effectively preventing impurities from entering the check valve body and causing blockage.

[0008] Preferably, the filter assembly is cylindrical in shape, and the filter assembly and the anti-clogging chamber are slidably connected. This slidably connected filter assembly is easier to maintain. When water flows through the filter assembly, small debris and sludge are trapped inside. The cylindrical shape of the filter assembly facilitates the storage of small debris and sludge, and cleaning simply requires turning the handle to slide the filter assembly out.

[0009] Preferably, a protective retainer is mounted on the surface of the anti-clogging chamber, and a protective sleeve is rotatably connected to the surface of the protective retainer. A bolt is threadedly connected between the protective sleeve and the protective retainer. Here, the hydraulic check valve is generally exposed to the outdoor environment during use. Installing the protective sleeve and retainer effectively protects the anti-clogging chamber, preventing rainwater corrosion of the threads of the first and second fixed sleeves and thus affecting the service life of the check valve.

[0010] Preferably, the protective retainer is fitted with the first fixing sleeve and the second fixing sleeve. Here, the fitting of the first fixing sleeve and the second fixing sleeve with the protective retainer can increase the airtightness of the check valve body and prevent rainwater from entering the interior of the protective retainer.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting a check valve body, water outlet, water inlet, anti-clogging chamber, first fixed sleeve, second fixed sleeve, filter assembly, first extension ring, second extension ring, filter plate, leakage hole, and handle structure, water flows in from the water inlet. After passing through the anti-clogging chamber, small debris and sludge inside are blocked inside the filter assembly. The cylindrical filter assembly is conducive to storing small debris and sludge, effectively preventing impurities from entering the interior of the check valve body, causing the check valve to become blocked, affecting the drainage and irrigation of the pipeline, and reducing the efficiency of water conservancy irrigation. When cleaning, you only need to turn the handle to slide the filter assembly out. By setting a protective textured structure, the anti-slip texture can increase the friction between the personnel's hands and the first and second fixed sleeves, thereby making it convenient for personnel to turn the first and second fixed sleeves to remove the anti-clogging chamber for maintenance.

[0013] 2. In this utility model, by setting a protective sleeve, a protective seat, and a bolt structure, the hydraulic check valve is generally exposed to the outdoor environment during use. Installing the protective sleeve and seat can effectively protect the anti-clogging chamber and prevent the threads of the first and second fixed sleeves from being corroded by rainwater, thus affecting the service life of the check valve. The first and second fixed sleeves fit snugly with the protective seat, which can increase the airtightness of the check valve body and prevent rainwater from entering the interior of the protective seat.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-5 This utility model provides a technical solution: a hydraulic check valve for preventing blockage, comprising a check valve body 1 and an inlet 3. An outlet 2 is fixedly installed on the surface of the check valve body 1. An anti-blockage chamber 4 is placed between the check valve body 1 and the inlet 3. A first fixing sleeve 5 is threadedly connected to the anti-blockage chamber 4 and the check valve body 1. A second fixing sleeve 6 is threadedly connected to the inlet 3 and the anti-blockage chamber 4. A first extension ring 9 is fixedly installed on the surface of the anti-blockage chamber 4, and a second extension ring 10 is fixedly installed on the surface of the inlet 3. The inner surface of the anti-blockage chamber 4... A filter assembly 8 is installed in the part, and a filter plate 11 is fixedly installed on the surface of the filter assembly 8. Leakage holes 12 are opened on the surface of the filter assembly 8, and a handle 13 is rotatably connected to the surface of the filter assembly 8. An activated carbon plate 7 is fixedly installed inside the anti-clogging chamber 4, located directly behind the filter assembly 8. The activated carbon plate 7 can further adsorb impurities in the river water, thereby preventing finer impurities from entering the interior of the check valve body 1 and causing damage to the internal parts of the check valve. The first fixing sleeve 5 and the second fixing sleeve 6 are both on the surface of the anti-clogging chamber 4. The surfaces of both the first fixing sleeve 5 and the second fixing sleeve 6 are provided with anti-slip textures 14. These textures increase the friction between the user's hand and the first fixing sleeve 5 and the second fixing sleeve 6, facilitating the unslip operation of the first fixing sleeve 5 and the second fixing sleeve 6. The anti-clogging chamber 4 is located between the inlet 3 and the check valve body 1. Water enters from the inlet 3, passes through the anti-clogging chamber 4, and then enters the interior of the check valve body 1, finally flowing out from the outlet 2. The anti-clogging chamber 4 prevents water from entering the check valve body. When the water flows into the body 1, it is filtered first to effectively prevent impurities from entering the body 1 of the check valve and causing the check valve to become clogged. The filter assembly 8 is cylindrical in shape and is connected to the anti-clogging chamber 4 by a sliding connection. The sliding connection of the filter assembly 8 makes it easier to maintain. When the water flows through the filter assembly 8, small debris and sludge inside the filter assembly 8 will be blocked inside the filter assembly 8. The cylindrical shape of the filter assembly 8 is conducive to storing small debris and sludge. When cleaning, you only need to turn the handle 13 to slide the filter assembly 8 out.

[0025] Example 2

[0026] Please see Figure 2 A protective retainer 15 is mounted on the surface of the anti-clogging chamber 4. A protective sleeve 16 is rotatably connected to the surface of the protective retainer 15. A bolt 17 is threadedly connected between the protective sleeve 16 and the protective retainer 15. When the hydraulic check valve is in use, it is generally exposed to the outdoor environment. Installing the protective sleeve 16 and the retainer can effectively protect the anti-clogging chamber 4 and prevent the threads of the first fixed sleeve 5 and the second fixed sleeve 6 from being corroded by rainwater, which would affect the service life of the check valve. The protective retainer 15 fits into the first fixed sleeve 5 and the second fixed sleeve 6. The fit between the first fixed sleeve 5 and the second fixed sleeve 6 and the protective retainer 15 can increase the airtightness of the check valve body 1 and prevent rainwater from entering the interior of the protective retainer 15.

[0027] Working principle: In use, first align the first extension ring 9 on the surface of the anti-clogging chamber 4 with the check valve body 1, slide the connection, and then hold the first fixing sleeve 5 to fix the anti-clogging chamber 4 to the check valve body 1. Then connect the second extension ring 10 on the surface of the inlet 3 to the anti-clogging chamber 4, and hold the second fixing sleeve 6 to fix the anti-clogging chamber 4 to the inlet 3. Water flows in from the inlet 3. The anti-slip texture 14 increases the friction between the operator's hand and the first fixing sleeve 5 and the second fixing sleeve 6, making it easier for the operator to turn the first fixing sleeve 5 and the second fixing sleeve 6. After passing through the anti-clogging chamber 4, the water enters the check valve body. The water flows out from the outlet 2. The anti-clogging chamber 4 filters the water before it enters the body of the check valve 1, effectively preventing impurities from entering the body of the check valve 1. Then, the protective seat 15 and the protective sleeve 16 are attached to the anti-clogging chamber 4, and the protective seat 15 and the protective sleeve 16 are fixed with bolts 17. This effectively protects the anti-clogging chamber 4 and prevents the threads of the first fixed sleeve 5 and the second fixed sleeve 6 from being corroded by rainwater, which would affect the service life of the check valve. When cleaning, simply turn the handle 13 to slide the filter assembly 8 out.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
