Description

Technical Field

[0001] This utility model relates to the field of irrigation two-way valve technology, and in particular to an assembled agricultural irrigation two-way valve. Background Technology

[0002] In the current technology, with the further development of agricultural modernization and large-scale production, various agricultural machinery has been gradually applied to the agricultural field. In the field of agricultural irrigation, mechanized irrigation operations have also begun. Currently, when irrigating farmland, devices are used to generate high water pressure, which then flows through water pipes and valves for efficient irrigation. However, existing irrigation valves can only meet the fluid passage requirements and do not have metering functions. They cannot detect the flow rate of liquid materials, nor can they simultaneously monitor the flow rate and pressure in real time. Furthermore, their valve bodies are usually composed of an integrated structure, which is not convenient for assembly and use. If any part is damaged, the entire valve will be scrapped, making it inconvenient for subsequent disassembly and maintenance, shortening its service life, and increasing the cost of use.

[0003] Chinese utility model patent application number 202022320588.2 discloses a water-hydraulic two-way threaded metering and regulating valve, including a valve body, an electric actuator, and a feed pipe. The electric actuator is fixed to the top of the valve body by bolts. A feed pipe is welded to one end of the valve body. A circular structural plate is fixed inside the feed pipe by a groove. A connecting rod is sleeved inside the circular structural plate. A small rubber plate is fixed to one end of the connecting rod by bolts, and a large rubber plate is fixed to the other end of the connecting rod by bolts. An arc-shaped groove is opened through one side of the circular structural plate. A discharge pipe is welded to the other end of the valve body. However, although this water-hydraulic two-way threaded metering and regulating valve can detect the flow rate of liquid, it cannot simultaneously monitor the flow rate and pressure in real time. Furthermore, its valve body is usually composed of a one-piece structure, which is inconvenient for assembly and use. If any part is damaged, the entire valve will be scrapped, which is not convenient for subsequent disassembly and maintenance, shortens its service life, and increases the cost of use.

[0025] Example 1:

[0026] An assembled agricultural irrigation two-way valve includes a valve body 1, which adopts a ball valve structure.

[0027] The valve housing mechanism includes a valve housing body 2 and mounting ports 3. The valve housing body 2 is disposed outside the valve body 1 and sleeved with the valve body 1. The valve housing body 2 is conformally designed to fit the valve body 1. Two sets of mounting ports 3 are symmetrically arranged at both ends of the valve housing body 2 and integrally formed with the valve housing body 2. The valve housing mechanism, through the cooperation of the valve housing body 2 and the mounting ports 3, constitutes an assembled valve housing structure outside the valve body 1. The valve housing body 2 serves as the valve housing structure on the outside of the valve body 1 for assembly and cooperation with the detection mechanism and the valve cover mechanism. The mounting ports 3 serve as the mounting structure at the end of the valve housing body 2 to meet the connection and installation requirements of the two-way valve with pipeline components or flanges in agricultural irrigation systems. A cross-sectional view of embodiment one of this utility model is shown below. Figure 2 As shown.

[0028] The end of the installation port 3 is set as an open structure and its inner side is provided with an internal thread structure. The two-way valve is connected and installed to the pipeline components or flanges in the agricultural irrigation system through the internal thread structure. The internal thread is used as the installation connection structure inside the installation port 3 to meet the installation requirements of the two-way valve.

[0029] The detection mechanism includes a flow detection port 4, a flow pressure cap 5, and a pressure detection port 6. The flow detection port 4 is located between one set of mounting ports 3 and the valve body 2, and penetrates the side wall of the corresponding mounting port 3. The flow pressure cap 5 is located at the flow detection port 4 and is fixedly connected to the corresponding mounting port 3 by screws. The pressure detection port 6 is located between the mounting port 3 away from the flow detection port 4 and the valve body 2, and penetrates the side wall of the corresponding mounting port 3. A turbine flow detector is press-fitted onto the inner side of the flow detection port 4 through the flow pressure cap 5. A pressure gauge is assembled onto the inner side of the pressure detection port 6 through an internal thread structure. The detection mechanism, through the cooperation of the flow detection port 4, the flow pressure cap 5, and the pressure detection port 6, forms a built-in detection structure to detect the flow rate and pressure of the fluid in the two-way valve. The flow detection port 4 provides mounting support for the turbine flow detector, the flow pressure cap 5 presses the turbine flow detector onto the flow detection port 4, and the pressure detection port 6 provides a mounting base for the pressure gauge to cooperate with the corresponding internal thread to provide mounting support for the pressure gauge. A schematic diagram of the cooperation between the detection mechanism and the valve body mechanism in Embodiment 1 of this utility model is shown below. Figure 3 As shown.

[0030] The valve cover mechanism includes a valve cover body 7 and mounting screws 8.

The two sets of mounting screws 8 are symmetrically arranged on both sides of the connection between the valve cover body 7 and the valve body body 2 and are threaded through the valve cover body 7 and the valve body body 2. The valve cover body 7 is fixedly connected to the valve body body 2 by the mounting screws 8. The valve cover mechanism, through the cooperation of the valve cover body 7 and the mounting screws 8, forms a detachable valve cover structure at the upper end of the valve body body 2. The valve cover body 7 is used to form a detachable valve cover structure at the upper end of the valve body body 2 to communicate with the valve body body 2 to form an assembled valve body 1 structure. The mounting screws 8 are used to realize the detachable installation connection between the valve cover body 7 and the valve body body 2.

[0031] It also includes a valve ball 9 and a drive rod 10. The valve ball 9 is disposed inside the valve body 1 and is rotatably connected to the valve body 1. The drive rod 10 is disposed at the upper end of the valve ball 9 and is fixedly connected to the valve ball 9. The drive rod 10 protrudes from the valve body 1 and the valve cover body 7. The valve ball 9 is used as an opening and closing structure inside the valve body 1. The valve ball 9 can be driven to rotate relative to the valve body 1 by the drive rod 10 to control the opening and closing of the valve body 1. The drive rod 10 is used to drive the valve ball 9 to rotate relative to the valve body 1.

[0032] Example 2:

[0033] Based on Embodiment 1, a flange mechanism is also included. The flange mechanism includes a connecting end pipe 11 and a mounting flange 12. The connecting end pipe 11 is assembled at the end of the mounting port 3 away from the valve body 2, and part of it protrudes from the mounting port 3.

The flange mechanism, through the cooperation of the connecting end pipe 11 and the mounting flange 12, constitutes a detachable flange structure at the end of the two-way valve. The connecting end pipe 11 provides mounting support for the mounting flange 12 and detachably assembles the mounting flange 12 onto the mounting port 3. The mounting flange 12, under the action of the connecting end pipe 11, constitutes a detachable flange structure at the end of the two-way valve. A cross-sectional view of Embodiment 2 of this utility model is shown below. Figure 4 As shown.

[0034] It also includes mounting through holes 13, which are provided in several groups. These groups of mounting through holes 13 are evenly spaced and arranged around the side of the mounting flange 12, penetrating the mounting flange 12. The mounting through holes 13 serve as through-hole structures on the mounting flange 12, thereby meeting the installation requirements of the mounting flange 12. A schematic diagram of the cooperation between the mounting through holes 13 and the mounting flange 12 in Embodiment 2 of this utility model is shown below. Figure 5 As shown.

[0035] In this technical solution, the two-way valve is made of PVC material.

[0036] Working principle:

[0037] In use, the two-way valve can be directly installed in the agricultural irrigation system through the internal thread on the inside of the installation port 3, or the flange mechanism can be assembled in the installation port 3 and the two-way valve can be installed in the agricultural irrigation system through the flange mechanism. In use, the flow rate and pressure of the fluid in the two-way valve can be detected by a turbine flow detector and a pressure gauge.

[0038] The beneficial effects of this utility model are that the valve shell mechanism and the valve cover mechanism cooperate to form an assembled shell structure, which avoids the whole being scrapped due to damage to a certain part, facilitates the subsequent disassembly and maintenance work, increases the service life of the two-way valve, reduces the cost of use, and the inner side of its end is set with a threaded structure, which facilitates the assembly and use with other pipeline components or flanges. It is equipped with a detection mechanism, which can simultaneously detect flow and pressure through the built-in detection structure, making it highly functional.
