Description

Technical Field

[0001] This utility model relates to the field of poultry farming water line technology, specifically a one-way drainage device for the end of a poultry farming water line. Background Technology

[0002] In large-scale farms, high-pressure flushing is required to ensure the cleanliness of the water line system. As the scale of farming continues to expand, the number of chickens per house increases, the number of cage layers increases, and the number of water lines per house increases accordingly. When flushing the water lines, the farm workers need to first open the drain valve at the end of the water line, and then open the flushing valve at the front end of the water line. After flushing, the flushing valve at the front end needs to be closed first, and then the drain valve at the end needs to be closed.

[0003] In actual production, operational errors are easily made. For example, closing the drain valve before closing the flushing valve can cause excessive pressure within the water line, leading to damage to the equipment. Furthermore, closing the front flushing valve after flushing can prevent the complete removal of residual contaminants from the pipes, affecting the cleanliness of the water line. Additionally, during the flushing of the upper water line, wastewater may flow backward through the drain pipe and the lower water level indicator pipe into the lower water line, also affecting its cleanliness. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a one-way drainage device for the end of a water line in poultry farming, so as to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a one-way drainage device for the end of a water line in poultry farming, comprising a water line body and a flushing valve, wherein the flushing valve is connected to one end of the water line body, and a three-way connector is fixedly connected to the other end of the water line body. A water level display tube for observing the water level is installed in the vertical interface of the three-way connector, and a connecting pipe is installed in the horizontal interface of the three-way connector. The other end of the connecting pipe is connected to a drain pipe, and a one-way drain valve for preventing sewage backflow is provided between the connecting pipe and the drain pipe.

[0006] As an optimization, the one-way drain valve includes a housing, a connecting pipe installed inside one end of the housing, a connecting part installed inside the other end of the housing, a drain connector fixedly installed at the end of the connecting part, a guide sleeve fixedly installed inside the housing, a through hole opened inside the guide sleeve, a valve core slidably inserted into the center of the guide sleeve, a blocking plate fixedly installed on the inner wall of the housing corresponding to the valve core, and a transmission component between the valve core and the guide sleeve for driving the valve core to press against the blocking plate. The housing can be blocked by the transmission component, thereby preventing sewage backflow.

[0007] As an optimization, the transmission component is a spring fixedly installed between the valve core and the guide sleeve, and the spring force value of the spring is less than the drainage water pressure. The spring force itself can drive the valve core to abut against the blockage plate and close, thereby blocking the outer shell to prevent sewage backflow.

[0008] As an optimization, the transmission component includes a cylindrical shell fixedly installed at the center of the guide sleeve. A magnetic slider is slidably connected inside the cylindrical shell, and one end of the valve core inserted into the cylindrical shell is fixedly connected to the magnetic slider. A tension spring is fixedly installed between the magnetic slider and the top wall of the cylindrical shell. An electromagnet is fixedly installed inside the cylindrical shell. By activating the electromagnet to generate magnetism, the magnetic slider can be attracted, thus pulling the valve core away from the blockage plate, thereby ensuring unobstructed drainage inside the outer shell.

[0009] As an optimization, the transmission component includes a sealing shell fixedly installed in the center of the guide sleeve, an electric push rod fixedly installed inside the sealing shell, and the valve core fixedly installed in the telescopic end of the electric push rod. By activating the electric push rod to extend or retract, the valve core can be driven to close against the side of the blocking plate or open away from the blocking plate.

[0010] As an optimization, a rubber sealing gasket is provided on one side of the inclined surface of the valve core, and the side of the plug plate that abuts against the valve core is also inclined and is provided with a rubber sealing gasket. The sealing performance can be improved by the abutment between the valve core and the plug plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The one-way drain valve opens automatically during rinsing due to the pressure of the rinsing water and closes after rinsing is complete. The water pressure in the water line naturally releases, causing the one-way drain valve to close automatically. When rinsing the upper water line, the sewage will be discharged along the drain pipe, and the one-way drain valve is in the closed state at this time, so it will not flow back into the lower water line, thus ensuring the cleanliness of the inside of the water line. When the water pressure inside the water line is greater than the elastic force of the spring in the drain valve, the valve core will separate from the plug plate. At this time, the water inside the water line will be discharged outward through the through hole and drain joint in the guide sleeve. When the pressure inside the water line is less than the elastic force of the spring, the valve core will automatically close, and the valve core will fit tightly with the plug plate to ensure the normal operation of the water line equipment.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 A one-way drainage device for the end of a water line in poultry farming includes a water line body 1 and a flushing valve 2. The flushing valve 2 is connected to one end of the water line body 1, and a three-way connector 3 is fixedly connected to the other end of the water line body 1. A water level display tube 4 for observing the water level is installed in the vertical interface of the three-way connector 3, and a connecting pipe 5 is installed in the horizontal interface of the three-way connector 3. The other end of the connecting pipe 5 is connected to a drain pipe 6, and a one-way drain valve 7 for preventing sewage backflow is provided between the connecting pipe 5 and the drain pipe 6. Please see Figure 5-6The one-way drain valve 7 includes a housing 8, a connecting pipe 5 installed inside one end of the housing 8, a connecting part 9 installed inside the other end of the housing 8, a drain connector 10 fixedly installed at the end of the connecting part 9, a guide sleeve 11 fixedly installed inside the housing 8, a through hole 12 opened inside the guide sleeve 11, a valve core 13 slidably inserted into the center of the guide sleeve 11, a blocking plate 14 fixedly installed on the inner wall of the housing 8 corresponding to the valve core 13, a transmission component is provided between the valve core 13 and the guide sleeve 11 to drive the valve core 13 to press against the blocking plate 14, the transmission component will drive the valve core 13 to close against the side of the blocking plate 14, thus blocking the housing 8 and preventing sewage backflow. A rubber sealing gasket is provided on one side of the inclined surface of the valve core 13, and the side of the blocking plate 14 that abuts against the valve core 13 is also inclined and is also provided with a rubber sealing gasket. The sealing performance can be improved by the abutment between the valve core 13 and the blocking plate 14. First embodiment of the transmission component: Please refer to Figure 5-6 The transmission component is a spring 15 fixedly installed between the valve core 13 and the guide sleeve 11. The spring force of the spring 15 is less than the drainage water pressure. The spring force of the spring 15 itself can drive the valve core 13 to abut against the block plate 14 and close, thereby blocking the outer shell 8 to prevent sewage backflow. When the connecting pipe 5 drains water, it can push the valve core 13 away from the block plate 14 and compress the spring 15, thereby ensuring that the drainage from the outer shell 8 is unobstructed. Second embodiment of the transmission component: Please refer to Figure 7-8 The transmission component includes a cylindrical shell 16 fixedly installed in the center of the guide sleeve 11. A magnetic slider 17 is slidably connected inside the cylindrical shell 16, and one end of the valve core 13 inserted into the cylindrical shell 16 is fixedly connected to the magnetic slider 17. A tension spring 18 is fixedly installed between the magnetic slider 17 and the top wall of the cylindrical shell 16. An electromagnet 19 is fixedly installed inside the cylindrical shell 16. By activating the electromagnet 19 to generate magnetism, the magnetic slider 17 can be attracted, thus pulling the valve core 13 away from the blockage plate 14. At the same time, the tension spring 18 is stretched, which ensures that the drainage inside the outer shell 8 is unobstructed. Through the elastic force of the tension spring 18, after the electromagnet 19 is closed, the valve core 13 will reset and press against the side of the blockage plate 14 to close, thereby preventing sewage backflow. The third embodiment of the transmission component: The transmission component includes a sealing shell fixedly installed in the center of the guide sleeve 11. An electric push rod is fixedly installed inside the sealing shell, and the valve core 13 is fixedly installed in the telescopic end of the electric push rod. By starting the electric push rod to extend and retract, the valve core 13 can be driven to close against the side of the blocking plate 14 or open away from the blocking plate 14. Therefore, the inside of the outer shell 8 will be blocked or cleared, thereby preventing sewage backflow.

[0016] Electromagnets, electric actuators, and other components are references to existing technologies, and will not be described in detail in this application. When using them, the preferred option can be selected provided that the driving conditions are met.

[0017] Working principle: When a single water line is not flushing, neither flushing valve 2 nor one-way drain valve 7 is open. During flushing, only flushing valve 2 at the front end is opened, while one-way drain valve 7 at the end automatically opens due to the pressure of the flushing water. After flushing is completed, flushing valve 2 at the front end closes, and the water pressure in the water line naturally releases, causing one-way drain valve 7 to close automatically. When multiple water lines are not flushing, neither flushing valve 2 nor one-way drain valve 7 is open. During flushing, only flushing valve 2 at the front end is opened, while one-way drain valve 7 at the end opens automatically due to the pressure of the flushing water. After flushing is completed, flushing valve 2 at the front end closes. After the water pressure in the water line naturally releases, one-way drain valve 7 will close automatically. When flushing the upper water line, sewage will be discharged along drain pipe 6. Since one-way drain valve 7 is closed at this time, it will not flow back into the lower water line, thus ensuring the cleanliness of the inside of the water line. The spring 15 inside the one-way drain valve 7 uses its own elasticity to drive the valve core 13 to close against the blockage plate 14 in the initial state when it is not subjected to external force. When the water pressure in the water line is greater than the elastic force of the spring 15 inside the drain valve, the valve core 13 will separate from the blockage plate 14. At this time, the water in the water line will be discharged outward through the through hole 12 and drain connector 10 opened in the guide sleeve 11. When the pressure in the water line is less than the elastic force of the spring 15, the valve core 13 will automatically close. The valve core 13 and the blockage plate 14 are tightly fitted to ensure the normal use of the water line equipment.

[0018] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
