Description

Technical Field

[0001] The utility model relates to a valve, more particularly to a fluid control valve which can be used for irrigation. Background Art

[0002] In the field of agricultural irrigation technology, a valve is usually used to control the opening and closing of a flow channel. The pipeline system is expensive and has the disadvantage of being inconvenient to operate. For irrigation of large areas of farmland, some use a water outlet to divide it into two or four pipelines, and install a valve on each pipeline for control; some use three-way or five-way valves to control each pipeline. During the irrigation process, the water inlet pipe is generally located below the ground, while the water outlet nozzle is located above the ground. Therefore, most of the multi-way valves currently used, such as three-way valves, four-way valves, and five-way valves, have a structure with a single input port and multiple output ports. The valve core assembly is arranged between the single input port and the multiple output ports. The valve core assembly is used to connect the single input port to one of the multiple output ports to achieve the switching of the channel. The existing valve core assembly design mainly uses the valve core assembly to convert the direction of the water channel to achieve the switching of the water channel. When water passes through the valve core assembly channel, the change of the water channel direction will cause a large water resistance problem. Utility Model Content

[0090] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0091] Reference Figure 1 As shown, the fluid control valve that can be used for irrigation of this embodiment includes:

[0092] A valve body 1 has at least one input interface 2, at least one output interface 3 and a valve seat body 4. The valve seat body 4 has a DC channel. The input interface 2 and the output interface 3 are respectively arranged at both ends of the DC channel, and the input interface 2 and the output interface 3 are connected through the DC channel.

[0093] A valve core assembly 5, which is arranged in the valve seat body 4 in a direct current channel, is used to control the direct current channel to conduct the input interface 2 and the output interface 3, or to close the input interface 2 and the output interface 3. During the use of the control valve, the fluid can enter the valve seat body 4 through the input interface 2, and then reach the valve core assembly 5, and finally enter the output interface 3. Due to the direct current channel design in the valve seat body 4, the flow path of the fluid through the valve core assembly 5 to the output interface 3 can be approximated as a direct current channel. This is compared with the curved flow channel designed in the prior art to cooperate with the reversing of the valve core assembly 5, which causes less resistance to the fluid.

[0094] Furthermore, the valve core assembly 5 includes:

[0095] A fixed valve disc 51 is fixedly mounted in the valve seat body 4 and is located in the direct current channel. The fixed valve disc 51 is provided with at least one through hole.

[0096] A movable valve disc 52 is rotatably mounted on the fixed valve disc 51. The movable valve disc 52 is provided with at least one guide hole. As the movable valve disc 52 rotates on the fixed valve disc 51, the DC channel is controlled by the alignment of the guide hole with the through hole in the fixed valve disc 51. During operation, the movable valve disc 52 rotates. When the guide hole overlaps with the through hole in the fixed valve disc 51, the DC channel is open, allowing fluid to pass through. If the alignment is not achieved, the DC channel is closed. In this embodiment, a fixed valve disc 51 and a movable valve disc 52 are combined into a planar valve structure. The on-off control of the flow channel is achieved by whether the guide hole and the through hole overlap. At the same time, the flow rate of the flow channel can be accurately controlled by partial overlap. By providing multiple through holes on the fixed valve disc 51, the effect of a group of valve core components 5 controlling multiple passages can be achieved. The valve seat body 4 in this embodiment is a part of the valve body 1 that is only used to install the valve core component 5. The direct current channel is a straight channel formed by the fluid passing through the valve core component 5, that is, the flow channel from one end of the valve core component 5 to the other end of the valve core component 5 is a straight-through structure. Figure 1 Taking the case of applying a flat valve core as shown in the figure as an example, during the use of the valve, the fluid first enters the input interface 2, and then passes directly through the guide holes and through holes overlapped by the fixed valve plate 51 and the movable valve plate 52, with minimal contact with the hole walls of the guide holes and through holes. In this way, compared with the prior art method of using a spherical core to change the flow direction by using the internal channel of the sphere and the method of blocking the stop valve core by the valve disc, the resistance encountered by the fluid is lower. During the use of irrigation, it has a better resistance reduction effect for fluids with higher viscosity such as water and fertilizer integrated.

[0097] Furthermore, the movable valve disc 52 is located at the end of the fixed valve disc 51 facing the input port 2. This arrangement ensures that when the fluid enters the direct flow channel, it first contacts the movable valve disc 52. The fluid pressure presses the movable valve disc 52 toward the fixed valve disc 51, thereby ensuring that the sealing effect between the movable valve disc 52 and the fixed valve disc is effectively maintained even after long-term use.

[0098] Furthermore, a blind hole is provided on the fixed valve disc 51. The blind hole and the guide hole are aligned to control whether the direct current channel is closed. When the blind hole and the guide hole overlap, fluid flow is blocked. The blind hole design not only achieves a closed valve effect, but also effectively stores foreign matter scraped off when the movable valve disc 52 operates on the fixed valve disc 51, preventing foreign matter from becoming stuck between the movable valve disc 52 and the fixed valve disc 51, causing the valve core assembly 5 to malfunction.

[0099] Furthermore, the blind hole can be formed directly in the fixed valve disc 51, or by combining a through hole in the fixed valve disc 51 with a closed cavity 6 in the valve seat body 4. In actual applications, ceramic discs are most suitable for the fixed valve disc 51 and the movable valve disc 52. Therefore, the blind hole is designed to pass through the through hole in the fixed valve disc 51 and the closed cavity 6 in the valve body, which can effectively facilitate the production of the fixed valve disc 51.

[0100] Furthermore, the output interface 3 is provided at the upper end of the valve seat body 4, and the input interface 2 is provided at the lower end of the valve seat body 4. The lower end of the control valve stem penetrates the valve seat body 4 from top to bottom, passes through the fixed valve disc 51, and is connected to the movable valve disc 52. With the above structure, the movable valve disc 52 can be located at the bottom and the fixed valve disc 51 can be located at the top. In this way, during use, the gravity of the movable valve disc 52 can offset part of the fluid pressure, avoiding the problem of the movable valve disc 52 and the fixed valve disc 51 being too tightly fitted, resulting in difficulty in rotation. In this embodiment, in order to effectively realize the control valve stem driving the movable valve disc 52, a circular hole is provided at the center of the fixed valve disc 51 for the control valve stem to pass through, and a waist-shaped hole, a hexagonal groove, a square hole, or a spline is provided at the center of the movable valve disc 52. This transmission structure cooperates with the control valve stem, so that the control valve stem can accurately and effectively drive the movable valve disc 52 to rotate.

[0101] Based on the basic structure of the fluid control valve that can be used for irrigation, the following embodiments are provided.

[0102] Example 1

[0103] Reference Figures 2 to 4 As shown, a bifurcated, two-way valve, one inlet and one outlet, with an adjustable valve core opening and a closing function of the fluid control valve structure is provided. In this embodiment 1, the input interface 2 of the valve body 1 includes a first input interface 21, and the output interface 3 includes a first output interface 31. The fixed valve plate 51 is provided with a first through hole 511 and a second blind hole 1512. The first through hole 511 is connected to the first output interface 31. The movable valve plate 52 is provided with a first guide hole 521. Figure 3 As shown in a to b, the first guide hole 521 is connected to the first input interface 21, and the fixed valve plate 51 and the movable valve plate 52 have the following matching relationship: Figure 3As shown in c and e, the first guide hole 521 is connected after coinciding with the first through hole 511, which is the valve open state. The fluid passes through the first input interface 21, then passes through the first guide hole 521, and then enters the output interface 3 through the first through hole 511, and is then delivered to the external device through the first output interface 31. Alternatively, the first guide hole 521 is closed after coinciding with the second blind hole 1512, which is the valve closed state. The fluid passes through the input interface 2, then passes through the first guide hole 521, and is blocked by the second blind hole 1512, so it cannot enter the first output interface 31 through the first through hole 511. , and then delivered to the external device through the first output interface 31, or the first guide hole 521 and the first through hole 511 are partially overlapped and connected to the valve opening adjustment state, the fluid passes through the first input interface 21, then passes through the first guide hole 521, and then enters the first through hole 511 into the first output interface 31, and then is delivered to the external device through the first output interface 31. The difference from the above is that by changing the size of the overlapping area between the first guide hole 521 and the first through hole 511, the size of the fluid flow rate can be changed, and the valve opening can be adjusted.

[0104] In the above-mentioned embodiment 1, the second blind hole 1512 is implemented as a blind hole structure directly opened on the fixed valve plate 51, or is composed of a through hole opened on the fixed valve plate 51 and a closed cavity 6 set in the valve seat body 4. At the same time, when the closed cavity 6 is set in the valve seat body 4, a water outlet cavity is also set accordingly to connect the first through hole 511 and the output interface 3. The number and position of the closed cavity 6 correspond one-to-one to the through holes on the fixed valve plate serving as blind holes, and the number and position of the water outlet cavity correspond one-to-one to the through holes on the fixed valve plate. Generally speaking, the water outlet cavity and the first through hole 511 are in a coincidence relationship, and the water outlet cavity is a direct current channel structure. The part connecting the water outlet cavity and the output interface 3 adopts an elbow design to achieve adaptive connection according to the actual position of the irrigation nozzle, which can be conveniently used in situations where the direction of the existing farmland irrigation flow channel changes, and can reduce the resistance strength caused by the change in flow channel direction.

[0105] Example 2, reference Figures 5 and 6 As shown, a three-part, three-way valve with one inlet and two outlets, an adjustable valve core opening, and a fluid control valve with a closing function is provided. In this embodiment 2, the input interface 2 of the valve body 1 includes a first input interface 21, and the output interface 3 includes a first output interface 31 and a second output interface 32. The fixed valve plate 51 is provided with a first through hole 511 and a second through hole 512 and a third blind hole 1513. The first through hole 511 and the second through hole 512 are respectively connected to the first output interface 31 and the second output interface 32. The movable valve plate 52 is provided with a first guide hole 521, as shown in FIG. Figure 6 As shown in a to b, the first guide hole 521 is connected to the first input interface 21, and the fixed valve plate 51 and the movable valve plate 52 have the following matching relationship: Figure 6 As shown in c to g, the first guide hole 521 is connected after overlapping with the first through hole 511, which is the open state of the first output interface 31. The fluid enters through the first input interface 21, and then enters the first output interface 31 after passing through the first guide hole 521 and the first through hole 511, and is output from the first output interface 31. Or the first guide hole 521 is connected after partially overlapping with the first through hole 511, which is the opening and flow adjustment state of the first output interface 31. The fluid enters through the first input interface 21, and then enters the first output interface 31 after passing through the first guide hole 521 and the first through hole 511, and is output from the first output interface 31. In the process of the fluid passing through the first guide hole 521 and the first through hole 511, the flow rate will change with the change of the overlap between the two. The overlap between the first guide hole 521 and the first through hole 511 is high, and the overlap between the third blind hole 1513 is low, then the flow rate The larger the value, the smaller the flow rate. Alternatively, the first guide hole 521 and the second through hole 512 are overlapped and connected, which is the open state of the second output interface 32. The fluid flow mode is similar to the open state of the first output interface 31, and is ultimately output through the second output interface 32. Alternatively, the first guide hole 521 and the second through hole 512 are partially overlapped and connected, which is the opening and flow adjustment state of the second output interface 32. The fluid flow mode is similar to the opening and flow adjustment state of the first output interface 31, and is ultimately output through the second output interface 32. Similarly, flow adjustment is achieved by the overlap between the first guide hole 521, the second through hole 512 and the third blind hole 1513. Alternatively, the first guide hole 521 and the third blind hole 1513 are overlapped and closed, which is the closed state. After the fluid enters the first guide hole 521 through the first input interface 21 and reaches the first guide hole 521, it will be blocked by the third blind hole 1513.

[0106] In the above-mentioned embodiment 2, the third blind hole 1513 is a blind hole structure directly provided on the fixed valve disc 51 , or is formed by providing a through hole on the fixed valve disc 51 and providing a closed cavity 6 in the valve seat body 4 .

[0107] Example 3, reference Figure 7 As shown, a three-part, three-way valve with one inlet and two outlets is provided, with single water outlet and double water outlet functions, and a fluid control valve without closure. In this embodiment 3, the structure of the valve body 1 is the same as that of embodiment 2. The input interface 2 of the valve body 1 includes a first input interface 21, and the output interface 3 includes a first output interface 31 and a second output interface 32. The fixed valve plate 51 is provided with a first through hole 511 and a second through hole 512 and a third blind hole 1513. The first through hole 511 and the second through hole 512 are respectively connected to the first output interface 31 and the second output interface 32. The movable valve plate 52 is provided with a first guide hole 521 and a second guide hole 522. Figure 7As shown in a to b, the first guide hole 521 and the second guide hole 522 are connected to the first input interface 21, and the fixed valve plate 51 and the movable valve plate 52 have the following matching relationship: Figure 7 As shown in c to e, the first guide hole 521 is connected after coinciding with the first through hole 511, and the second guide hole 522 is connected after coinciding with the second through hole 512, which are the first output interface 31 and the second output interface 32. The fluid passes through the first input interface 21, the first through hole 511 and the second through hole 512, and the first guide hole 521 and the second guide hole 522 into the first output interface 31 and the second output interface 32, realizing dual-channel synchronous output, or the first guide hole 521 is connected after coinciding with the second through hole 512, and the second guide hole 522 is closed after coinciding with the third blind hole 1513, which is the open state of the second output interface 32. , the third blind hole 1513 replaces the above-mentioned first through hole 511, so the fluid cannot enter the first through hole 511 through the second guide hole 522. At this time, the first output interface 31 is closed, and the fluid can enter the second through hole 512 through the first guide hole 521. Alternatively, the first guide hole 521 overlaps with the third blind hole 1513 and is closed, and the second guide hole 522 overlaps with the first through hole 511 and is connected, which is the open state of the first output interface 31. Referring to the above-mentioned fluid flow method, the second through hole 512 corresponding to the second output interface 32 is replaced by the third blind hole 1513, so the second output interface 32 is now in the closed state.

[0108] In the above embodiment 3, the third blind hole 1513 is a blind hole structure directly opened on the fixed valve plate 51 , or is composed of a through hole opened on the fixed valve plate 51 and a closed cavity 6 set in the valve seat body 4 .

[0109] Example 4, reference Figures 8 and 9 As shown, a three-part, four-way valve is provided, with one inlet and three outlets and no closing function. In this embodiment 6, the input interface 2 of the valve body 1 includes a first input interface 21, the output interface 3 includes a first output interface 31, a second output interface 32 and a third output interface 33, and the fixed valve plate 51 is provided with a first through hole 511, a second through hole 512 and a third through hole 513. The first through hole 511, the second through hole 512 and the third through hole 513 are respectively connected to the first output interface 31, the second output interface 32 and the third output interface 33, and the movable valve plate 52 is provided with a first guide hole 521. Figure 9 As shown in a to b, the first guide hole 521 is connected to the first input interface 21, and the fixed valve plate 51 and the movable valve plate 52 have the following matching relationship: Figure 9In steps c to e, the first guide hole 521 is connected after overlapping with the first through hole 511, which is the open state of the first output interface 31, or the first guide hole 521 is connected after overlapping with the second through hole 512, which is the open state of the second output interface 32, or the first guide hole 521 is connected after overlapping with the third through hole 513, which is the open state of the third output interface 33. During the process of the above three output interfaces 3 being open, the fluid flow mode is the same as that in Example 3.

[0110] Example 5, with reference to Figures 10 and 11 As shown, a four-part, two-way valve is provided, one inlet and one outlet, the valve core opening is adjustable, and it has a closing function.
