Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation pipeline technology, and more specifically, to an agricultural irrigation pipeline valve. Background Technology

[0002] Plastic valves, as key control components in agricultural irrigation pipelines, are widely used in field plastic pipe systems to achieve flexible opening and closing and flow regulation of localized irrigation areas. They have significant application value in large-scale farmland irrigation and precision irrigation scenarios such as small orchards and vegetable gardens. Currently, the agricultural irrigation field lacks dedicated valve structures and generally uses general-purpose ball valves as control switches. These ball valves achieve water flow interruption and flow regulation through the rotation of the central ball and the cooperation of an elastic sealing ring, and the pipeline is assembled and disassembled using structures such as pressure rings, pipe clamps, and nuts; the technology is relatively mature.

[0003] However, in engineering practice, it has been found that directly using general-purpose ball valves in agricultural irrigation scenarios has significant drawbacks: First, agricultural irrigation systems typically operate at lower pressures and have relatively relaxed sealing requirements; for some pipelines, valve installation positions only need to ensure no serious leakage occurs. While ball valves offer excellent sealing performance, their complex internal structure, comprising more than ten different parts, leads to cumbersome assembly processes, high mold development costs, and significant performance redundancy. This "using a sledgehammer to crack a nut" approach severely restricts production efficiency and increases installation costs in large-scale production applications. Second, ball valves require sealing designs at multiple critical locations, including the handle rotation area on the top of the valve body, port connections, the ball core rotation sealing interface, and the union structure. The excessive number of sealing points and the complex structure make troubleshooting and maintenance difficult, resulting in low maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the limitations of existing technologies in agricultural irrigation, which involve complex pipeline valve structures and high production and maintenance costs. This invention provides an agricultural irrigation pipeline valve that simplifies the valve structure, effectively reduces costs, and improves production and maintenance efficiency while meeting the sealing requirements of agricultural irrigation.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An agricultural irrigation pipeline valve is provided, comprising a first connecting pipe, a second connecting pipe, and a valve component. The axis of the first connecting pipe is offset from the axis of the second connecting pipe. A communication port is provided at the connection between the first connecting pipe and the second connecting pipe. The valve component is provided with an external interface and a valve plate portion. The valve component is rotatably connected to the first connecting pipe. The valve plate portion abuts against the inner wall of the first connecting pipe. The valve plate portion rotates around the axis of the first connecting pipe to open or close the communication port. The external interface connects the first connecting pipe to an external agricultural pipe.

[0006] During the operation of the above scheme, the agricultural pipeline is connected to the second connecting pipe of the valve and the external interface on the valve fitting during installation. When irrigation is required, the valve fitting is rotated so that the main body of the valve fitting moves away from the connection port, and the first connecting pipe and the second connecting pipe form a smooth water flow channel. When the water flow needs to be cut off, the valve fitting is simply rotated at a certain angle so that the valve plate of the valve fitting completely covers the connection port, thus achieving a sealed closure. Through the staggered arrangement of the axes and the rotary opening and closing method, reliable flow control is achieved with fewer moving parts. The valve fitting and the connecting pipe are directly connected by a rotary mechanism, eliminating the complex sealing structure and multi-part connection method of traditional ball valves. While ensuring the sealing requirements under low-pressure conditions, this significantly reduces processing costs and assembly complexity.

[0007] Furthermore, a sealing plate is installed on the valve plate. When the valve is in the closed state, the sealing plate seals the communication port. The valve also includes a connecting part, the edge of which is fixedly connected to the valve plate. The external interface is located inside the connecting part. The valve plate is an arc-shaped plate. When the communication port is opened, the valve plate fits against the inner wall of the first connecting pipe. When the communication port is closed, the sealing plate on the valve plate completely covers the communication port, achieving a sealed closure. During installation, the external agricultural pipe is connected to the external interface. The entire valve plate is installed between the first connecting pipe and the external agricultural pipe. The valve plate can rotate relative to the agricultural pipe and the first connecting pipe to achieve normal valve opening and closing functions.

[0008] Furthermore, the connecting part includes an abutting protrusion ring, which abuts against the end face of the first connecting pipe; the abutting protrusion ring completes the installation after abutting against the end face of the first connecting pipe. Since the external agricultural pipe is installed on the external interface of the valve component, the back pressure of the external agricultural pipe may push the valve component to slide in the cavity of the first connecting pipe. Therefore, the abutting protrusion ring is provided to limit the valve component.

[0009] Furthermore, it also includes a sealing ring. A first mounting groove is provided on the side of the connecting part near the abutting protrusion, and a second mounting groove is provided on the inner wall of the abutting protrusion. The sealing ring is installed in both the first mounting groove and the second mounting groove. The valve component is rotatably connected to the agricultural pipe and the first connecting pipe on both the inner and outer sides. Sealing rings need to be installed at both connection points to achieve basic sealing function and avoid serious water leakage problems. At the same time, the sealing ring itself has a certain degree of hardness and a certain degree of resilience. When under pressure, it can be installed on the valve component with small deformation, resulting in a good sealing effect.

[0010] Furthermore, the abutting protrusion is provided with a claw portion, and the outer wall of the first connecting pipe is provided with a snap-fit ​​protrusion, the claw portion abutting against the end face of the snap-fit ​​protrusion; along the axial direction of the first connecting pipe, the abutting protrusion can only achieve unidirectional limiting of the valve component, and the connection structure of the claw portion and the snap-fit ​​protrusion can lock the entire valve component onto the socket of the first connecting pipe, preventing it from detaching from the first connecting pipe along the axial direction of the first connecting pipe under the action of external pressure.

[0011] Furthermore, an installation arc is provided on the end face of the first connecting pipe, the abutting protrusion is connected to the installation arc, the abutting protrusion is provided with a limiting protrusion, the installation arc is provided with a limiting groove, and the limiting protrusion is inserted into the limiting groove; the valve needs to be completely closed and completely open. When the valve is rotated to the point where the limiting protrusion abuts against one end of the limiting groove, it can indicate to the operator that the valve plate has completely left the communication port, and when it is rotated to the other end of the limiting groove, it indicates that the valve plate has completely closed the communication port.

[0012] Furthermore, the mounting arc is provided with a clamping protrusion, which is used to abut against the outer wall of the external agricultural pipe. The external agricultural pipe is directly inserted into the external interface, and the strength of the connection is generally not very tight. After adding the clamping protrusion, when the agricultural pipe is inserted into the external interface, the clamping protrusion deforms, and the elastic force of the deformation clamps the agricultural pipe. At the same time, in conjunction with the back pressure outside the agricultural pipe, the pipe fitting is stably installed on the external interface.

[0013] Furthermore, the external interface is provided with a fence section, which is mesh-like; the water pressure in agricultural pipes may occasionally be high, and the fence section can divide the medium-high pressure water flow into smaller streams, thereby reducing the water pressure.

[0014] Furthermore, the valve plate portion is provided with reinforcing ribs on the surface facing the axis of the first connecting pipe, and one end of the reinforcing ribs extends to be fixedly connected to the fence portion; the plate of the fence portion near the valve plate portion extends to the surface of the valve plate portion to form reinforcing ribs (integral molding), which can improve the strength of the valve plate portion.

[0015] Furthermore, the abutting protrusion is also provided with a handle; the simple design of the handle makes it easy for the operator to turn the valve component and realize the basic function of opening and closing the valve.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. The axes of the first connecting pipe and the second connecting pipe are offset. A communication port is provided at the connection between the first and second connecting pipes. The valve component has an external interface. The valve component is rotatably connected to the first connecting pipe and rotates around the axis of the first connecting pipe. The external interface connects the first connecting pipe to an external agricultural pipe, achieving reliable flow control with fewer moving parts. The valve component and the connecting pipe adopt a direct rotary fit, eliminating the complex sealing structure and multi-part connection method of traditional ball valves. While ensuring the sealing requirements under low-pressure conditions, it significantly reduces processing costs and assembly complexity.

[0017] 2. The external interface is equipped with a fence section, which can divide the medium and high pressure water flow into smaller streams to reduce the water pressure; the plate extends to the surface of the valve plate to form reinforcing ribs, which can also improve the strength of the valve plate.

[0020] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0021] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0022] Example 1 This embodiment is a first embodiment of an agricultural irrigation pipeline valve, such as... Figures 1 to 3 as well as Figures 6 to 7 As shown, the device includes a first connecting pipe 100, a second connecting pipe 200, and a valve component 300. The axis of the first connecting pipe 100 is offset from the axis of the second connecting pipe 200. A communication port 400 is provided at the connection between the first connecting pipe 100 and the second connecting pipe 200. The valve component 300 is provided with an external interface 310 and a valve plate portion 320. The valve component 300 is rotatably connected to the first connecting pipe 100. The valve plate portion 320 abuts against the inner wall of the first connecting pipe 100. The valve plate portion 320 rotates around the axis of the first connecting pipe 100 and opens or closes the communication port 400. The external interface 310 connects the first connecting pipe 100 to an external agricultural pipe 500.

[0023] Here, misalignment refers to the absence of a common point between two axes, specifically the misalignment of the axis of the first connecting pipe 100 and the axis of the second connecting pipe 200. This misalignment can manifest as the two axes being perpendicular but not intersecting in space, parallel but not overlapping on the same plane, or neither perpendicular nor parallel in space, and not intersecting but forming an angle on a common projection plane. This embodiment employs the following method... Figure 1 The diagram shows misaligned forms that are parallel but not overlapping on the same plane.

[0024] A sealing plate 321 is installed on the valve plate 320. When the valve component 300 is in the closed state, the sealing plate 321 seals the communication port 400. Figure 6As shown, the valve component 300 also includes a connecting portion 330, the edge of which is fixedly connected to the valve plate portion 320, and the outer interface 310 is located inside the connecting portion 330. The valve plate portion 320 is an arc-shaped plate. When the communication port 400 is opened, the valve plate portion 320 fits against the inner wall of the first connecting pipe 100. When the communication port 400 is closed, the sealing element on the valve plate portion 320 completely covers the communication port 400, achieving a sealed closure. During installation, the external agricultural pipe 500 is connected to the outer interface 310, and the entire valve plate component is installed between the first connecting pipe 100 and the external agricultural pipe 500. The valve plate component can rotate relative to the agricultural pipe 500 and the first connecting pipe 100 to achieve normal valve opening and closing functions.

[0025] In addition, such as Figure 7 As shown, the back of the sealing sheet 321 is provided with several positioning protrusions 322. During installation, the positioning protrusions 322 are inserted into the mounting holes on the surface of the valve plate 320 to form an interference fit, which can effectively prevent the sealing sheet 321 from shifting during use.

[0026] Since the non-valve connection end of the external agricultural pipe 500 is fixed circumferentially along the pipeline axis, the rotation of the valve component 300 will not cause the external agricultural pipe 500 to rotate together.

[0027] Specifically, it also includes a sealing ring 600. The connecting part 330 is provided with a first mounting groove 332 on the side near the abutting protrusion 331, and a second mounting groove 312 is provided on the inner wall of the abutting protrusion 331. Both the first mounting groove 332 and the second mounting groove 312 are equipped with sealing rings 600. The valve component 300 is rotatably connected to the agricultural pipe 500 and the first connecting pipe 100 on both the inner and outer sides. Both connections need to be equipped with sealing rings 600 to achieve basic sealing function and avoid serious water leakage problems. At the same time, the sealing ring 600 itself has a certain hardness and a certain degree of resilience. When under pressure, it can be installed on the valve component 300 with small deformation, resulting in a good sealing effect.

[0028] The working principle of an agricultural irrigation pipeline valve in this embodiment is as follows: The agricultural pipe 500 is connected to the second connecting pipe 200 of the valve and the external interface 310 on the valve component 300. When the valve is closed, the valve component 300 is rotated, which drives the valve plate 320 to make the sealing plate 321 completely cover the communication port 400 between the first connecting pipe 100 and the second connecting pipe 200, thus achieving a sealed closure. When the valve is opened, the valve component 300 is rotated to make the valve plate 320 move away from the communication port 400, while maintaining the valve plate 320 in contact with the inner wall of the first connecting pipe 100, thus forming a smooth water flow channel.

[0029] The beneficial effects of this embodiment are: the arc-shaped valve plate structure maintains contact with the pipe wall during the opening and closing process, and the sealing and opening can be achieved by rotating the valve plate part 320 alone, which greatly simplifies the multiple sealing structure of traditional valves, effectively reduces costs and improves production and maintenance efficiency.

[0030] Example 2 This embodiment is a second embodiment of an agricultural irrigation pipeline valve, such as... Figures 3 to 6 As shown, the difference from Embodiment 1 is as follows: Specifically, the connecting part 330 includes an abutting protrusion 331, which abuts against the end face of the first connecting pipe 100. The abutting protrusion 331 is installed after it abuts against the end face of the first connecting pipe 100. Since the external agricultural pipe 500 is installed on the external interface 310 of the valve component 300, the back pressure of the external agricultural pipe 500 may push the valve component 300 to slide in the cavity of the first connecting pipe 100. Therefore, the abutting protrusion 331 is provided to limit the valve component 300.

[0031] Specifically, it also includes a sealing ring 600. The connecting part 330 is provided with a first mounting groove 332 on the side near the abutting protrusion 331, and a second mounting groove 312 is provided on the inner wall of the abutting protrusion 331. Both the first mounting groove 332 and the second mounting groove 312 are equipped with sealing rings 600. The valve component 300 is rotatably connected to the agricultural pipe 500 and the first connecting pipe 100 on both the inner and outer sides. Both connections need to be equipped with sealing rings 600 to achieve basic sealing function and avoid serious water leakage problems. At the same time, the sealing ring 600 itself has a certain hardness and a certain degree of resilience. When under pressure, it can be installed on the valve component 300 with small deformation, resulting in a good sealing effect.

[0032] Specifically, a handle 360 ​​is also provided on the abutting ring 331; the simple design of the handle 360 ​​makes it easy for the operator to turn the valve component 300 to realize the basic function of opening and closing the valve.

[0033] Installing the sealing ring 600 will inevitably increase the rotational resistance of the valve component 300. However, since the sealing requirements are not high, we selected a material with a low coefficient of friction to manufacture the O-ring with a smaller cross-sectional size, and used a precise groove design to control the compression ratio. At the same time, optimizing the surface finish and setting a handle 360 ​​of sufficient length can directly and effectively improve the operating feel of the final product.

[0034] Specifically, the abutting ring 331 is provided with a claw portion 340, and the outer wall of the first connecting pipe 100 is provided with a locking ring 110. The claw portion 340 abuts against the end face of the locking ring 110. Along the axial direction of the first connecting pipe 100, the abutting ring 331 can only achieve unidirectional limiting of the valve component 300. The connection structure between the claw portion 340 and the locking ring 110 can lock the entire valve component 300 onto the socket of the first connecting pipe 100, preventing it from detaching from the first connecting pipe 100 along the axial direction of the first connecting pipe 100 under the action of external pressure.

[0035] Specifically, such as Figure 5 As shown, an installation arc 120 is also provided on the end face of the first connecting pipe 100. The abutting protrusion 331 is connected to the installation arc 120. A limit protrusion 350 is provided on the abutting protrusion 331, and a limit groove 121 is provided on the installation arc 120. The limit protrusion 350 is inserted into the limit groove 121. The valve component 300 needs to be completely closed and completely opened. When the valve component 300 is rotated to the point where the limit protrusion 350 abuts against one end of the limit groove 121, it can indicate to the operator that the valve plate part 320 has completely left the communication port 400. When it is rotated to the other end of the limit groove 121, it indicates that the valve plate part 320 has completely closed the communication port 400.

[0036] Among them, such as Figure 3 As shown, the installation arc 120 is a semi-circular arc. When installing the valve component 300, first place the valve plate part 320 into the first connecting pipe 100, then clamp the claw part 340 onto the clamping protrusion ring 110, and finally press the valve component 300 so that the limiting protrusion 350 is pressed into the limiting groove 121 to complete the installation.

[0037] The working principle of an agricultural irrigation pipeline valve in this embodiment is as follows: During installation, the abutting protrusion 331 of the valve component 300 is aligned with the end face of the first connecting pipe 100. The axial positioning is completed by the engagement of the claw portion 340 with the outer wall of the first connecting pipe 100 and the engagement protrusion 110, thus preventing the valve component 300 from coming off under pipeline pressure.

[0038] During the rotation operation, the valve component 300 rotates around the axis of the first connecting pipe 100, and the valve plate portion 320 always remains in contact with the inner wall of the pipe. When the valve plate portion 320 rotates to contact one end of the limiting protrusion 350 and the limiting groove 121, the valve plate portion 320 completely leaves the connecting port 400, and the valve is in the fully open state; when the valve plate portion 320 rotates to the other end of the limiting groove 121, the sealing plate 321 on the valve plate portion 321 completely covers the connecting port 400, achieving a sealed closure.

[0039] The beneficial effects of this embodiment are: the two types of structural design, namely mechanical limiting and sealing, which are connected by a snap-fit ​​connection, not only ensure the convenience and stability of installation, but also ensure the sealing performance under low-pressure conditions in agricultural irrigation. At the same time, the tactile feedback of the limiting groove 121 indicates the opening and closing status of the valve, which significantly improves the intuitiveness and reliability of operation.

[0040] Example 3 This embodiment is a third embodiment of an agricultural irrigation pipeline valve, such as... Figure 3 and 6 As shown, the difference from Embodiment 1 is as follows: Specifically, the external interface 310 is provided with a fence section 311, which is mesh-like. In this embodiment, the fence section 311 is composed of several horizontal and vertical intersecting plates. The water pressure of the agricultural pipe 500 may occasionally be high. The fence section 311 can divide the medium and high pressure water flow into smaller water flows to reduce the water pressure.

[0041] In addition, if larger particles of impurities in the water get stuck on the fence section 311, the staff should first turn off the main water supply, then remove the agricultural pipe 500 from the valve 300 and remove the valve 300 to clean the impurities.

[0042] Specifically, a reinforcing rib is provided on the surface of the valve plate portion 320 facing the axis of the first connecting pipe 100, and one end of the reinforcing rib extends to be fixedly connected to the fence portion 311; the plate of the fence portion 311 near the valve plate portion 320 extends to the surface of the valve plate portion 320 to form a reinforcing rib (integral molding), which can improve the strength of the valve plate portion 320.

[0043] Specifically, a handle 360 ​​is also provided on the abutting ring 331; the simple design of the handle 360 ​​makes it easy for the operator to turn the valve component 300 to realize the basic function of opening and closing the valve.

[0044] The working principle of an agricultural irrigation pipeline valve in this embodiment is as follows: When valve 300 is in the open position, water flows from the second connecting pipe 200 to the first connecting pipe 100. When the water pressure in the agricultural pipe 500 occasionally rises, the higher-pressure water flow contacts valve 300 and first impacts the fence section 311. The grid structure of the fence section 311 divides, impacts, and guides a concentrated, high-flow-rate, high-speed water flow into multiple smaller, dispersed flows with relatively lower velocity. This process effectively dissipates the concentrated impact energy of the water flow and significantly reduces the local pressure of the water flow downstream (i.e., in the agricultural pipe 500 connected to valve 300).

[0045] The plates extending from the fence section 311 toward the valve plate section 320 have their ends in close contact with the surface of the valve plate section 320. These plates act as reinforcing ribs in the physical structure, transforming the valve plate section 320 from a potentially large flat plate into a reinforced structure supported at multiple points. This enhances the rigidity and deformation resistance of the valve plate section 320, enabling it to better withstand the impact of water pressure without bending or deforming.

[0046] The beneficial effects of this embodiment are: the setting of the fence part 311 not only plays a role in pressure reduction, rectification and protective sealing at the fluid level, but also strengthens the mechanical strength of the valve body at the structural level, ensuring the durability and reliability of the valve under low-pressure conditions in agricultural irrigation.

[0047] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
