Description

Technical Field

[0001] This utility model relates to the field of directional valve technology, specifically a slanted directional valve. Background Technology

[0002] A directional control valve is a directional control valve with two or more flow patterns and two or more ports. It is a valve that realizes the communication, cut-off and reversal of hydraulic oil flow, as well as pressure unloading and sequential action control. It is a directional control valve that relies on the relative movement of the valve core and the valve body.

[0003] The prior art patent document CN214999557U provides a reversing valve, including a hollow valve body, which is connected to an external fan through a first connecting pipe, and a connecting rod is connected to an external drive source. The external drive source drives the connecting rod to move, so that the air guide cavity is connected to the first and third connecting pipes, or to the first and third connecting pipes, thereby realizing the switching between exhaust and blower operation between the second and third connecting pipes. The structure is simple, and one set of fans can realize the switching of two pipelines, eliminating the need for two sets of fans, which facilitates the control of fan operation and reduces energy consumption. One end of the connecting rod extends to the valve body and is connected to the external drive source. Setting the external drive source outside the valve body is simpler in structure and easier to install than setting the external drive source inside the valve body, and can reduce the volume of the valve body.

[0004] Although the device has many beneficial effects, the following problems still exist: During the use of the device, the right-angle reversing structure is easily subjected to fluid impact and eddies, resulting in high pressure loss and insufficient reversing response speed; secondly, the direct threaded connection between the pipe and the external pipeline during the use of the device is prone to loosening, affecting the connection stability and sealing effect, which needs to be improved. In view of this, we propose an oblique reversing valve. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the issues of the aforementioned right-angle reversing structure being susceptible to fluid impact and eddies, resulting in high pressure loss, insufficient reversing response speed, and the direct threaded connection between the pipe and external pipeline being prone to loosening and affecting connection stability and sealing performance, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a slanted reversing valve. The slanted outlet structure can reduce fluid impact and eddies, reduce pressure loss, improve response speed, make the connection between the pipe and the external pipeline more stable, avoid loosening, and effectively improve the sealing effect.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A diagonal directional control valve includes a valve body with a first connecting pipe at the bottom and second connecting pipes on both sides of the outer circumference of the valve body. A directional control assembly is located at the top of the valve body, comprising two fixed plates. A hydraulic cylinder is mounted on the top of each fixed plate, and a movable plate is located at the output end of the hydraulic cylinder. A limit ring is rotatably connected to the outer circumference of the movable plate, and a valve core is located at the bottom of the limit ring. A through hole is formed on the outer circumference of the valve core, and a spiral groove is formed on the other side of the outer circumference of the valve core. A guide block is slidably connected to the spiral groove on the inner circumference of the valve body. Connecting assemblies are located at the other ends of both the first and second connecting pipes. The hydraulic cylinder is electrically connected to an external power source. The asymmetrical design of the two second connecting pipes results in a non-linear change in the inlet and outlet flow characteristics under the same displacement, making it suitable for hydraulic systems requiring rapid response.

[0012] In a preferred embodiment of the oblique-port directional valve of this utility model, the connecting assembly includes a first flange ring, a positioning groove on the side wall of the first flange ring, a receiving groove at one end of the side wall of the positioning groove, a second flange ring on the side wall of the first flange ring, and multiple positioning plates on the side wall of the second flange ring. A sealing ring located on the side wall of the second flange ring is provided on the inner circumference of each positioning plate. Both the side walls of the first and second flange rings have multiple connecting holes. Inserting the sealing ring into the positioning groove facilitates positioning and ensures alignment of the first and second flange rings, preventing misalignment from affecting the connection seal.

[0013] In a preferred embodiment of the oblique-port directional valve of this utility model, the output end of the hydraulic cylinder is slidably connected to the top of the valve body, and the cross-section of the limiting ring is inverted L-shaped.

[0014] In a preferred embodiment of the oblique-port reversing valve of this utility model, the size of the through hole matches the inner diameter of the second connecting pipe, and the distance between the through hole and the bottom of the valve core is greater than the height difference between the two second connecting pipes.

[0015] In a preferred embodiment of the oblique-port reversing valve of this utility model, the two second connecting pipes are inclined, the two second connecting pipes are inclined at the same angle and in the same direction, and the valve core is open at the bottom.

[0016] In a preferred embodiment of the oblique-port reversing valve of this utility model, the cross-section of the positioning plate is L-shaped, and the dimensions and positions of the ends of the positioning plate match the dimensions and positions of the receiving groove.

[0017] In a preferred embodiment of the oblique-port directional valve of this utility model, the sealing ring is made of silicone rubber, and the connecting holes on the sidewalls of the first flange ring and the second flange ring are staggered. Silicone rubber has strong weather resistance, is easy to resist aging, and effectively improves service life.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of oblique-port directional valve moves by opening a hydraulic cylinder to move a moving plate, which in turn moves a limit ring and then a valve core. A guide block moves the valve core along a spiral groove, causing the through hole to move and rotate to another second pipe. The fluid input from the first pipe flows from the valve core into the other second pipe, facilitating the switching of fluid outlets for directional changes. The oblique outlet structure of the second pipe reduces fluid impact and eddies, lowers pressure loss, and effectively improves response speed.

[0021] This type of oblique-port directional valve connects the second flange ring at one end of the external pipeline to the first flange ring. After inserting the positioning plate into the positioning groove, the second flange ring is rotated, causing the end of the positioning plate to rotate and insert into the receiving groove. This aligns the connecting hole on the side wall of the first flange ring with the connecting hole on the side wall of the second flange ring. Tightening in the bolts improves stability and prevents loosening that could lead to separation. The sealing ring effectively improves the sealing performance and prevents fluid leakage.

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural schematic diagram of an embodiment of a slanted-port reversing valve, including:

[0035] Please see Figures 1-5This embodiment of a diagonal directional valve includes a valve body 1. A first connecting pipe 2 is welded to the bottom of the valve body 1, and second connecting pipes 3 are welded to both sides of the outer circumference of the valve body 1. A directional assembly 4 is fixedly mounted on the top of the valve body 1. The directional assembly 4 includes two fixed plates 401. A hydraulic cylinder 402 is fixedly mounted on the top of the fixed plate 401. A movable plate 403 is fixedly mounted on the output end of the hydraulic cylinder 402. A limit ring 404 is rotatably connected to the outer circumference of the movable plate 403. A valve core 405 is fixedly mounted at the bottom of the limit ring 404. A through hole 406 is opened on the outer circumference of the valve core 405. A spiral groove 407 is opened on the other side of the outer circumference of the valve core 405. A slidable connection between the valve core 1 and the spiral groove 407 is fixedly mounted on the inner circumference of the valve body 1. The guide block 408 is connected to the other end of the first pipe 2 and the second pipe 3, and the connecting component 5 is fixedly provided. The hydraulic cylinder 402 is electrically connected to an external power source. By opening the hydraulic cylinder 402, the moving plate 403 is moved, thereby moving the limit ring 404 and driving the valve core 405 to move. The guide block 408 drives the valve core 405 to rotate along the spiral groove 407, thereby moving the through hole 406 and rotating it to the other second pipe 3. The fluid input from the first pipe 2 flows from the valve core 405 into the other second pipe 3, which facilitates switching the fluid outlet for reversal. The inclined outlet structure of the second pipe 3 can reduce fluid impact and eddy current, reduce pressure loss, and effectively improve response speed.

[0036] It is worth noting that, to prevent loosening from affecting the stability and sealing of the connection, the connecting assembly 5 specifically includes a first flange ring 501. The first flange ring 501 has a positioning groove 502 on its side wall, and a receiving groove 503 is formed at one end of the side wall of the positioning groove 502. A second flange ring 504 is threadedly connected to the side wall of the first flange ring 501. Multiple positioning plates 505 are fixedly mounted on the side wall of the second flange ring 504. A sealing ring 506 located on the side wall of the second flange ring 504 is fixedly mounted on the inner circumference of each positioning plate 505. The side wall of the first flange ring 501 and the second flange ring 504... Multiple connection holes 507 are provided on the side wall of flange 504. The second flange ring 504 at one end of the external pipe is spliced ​​with the first flange ring 501. After the positioning plate 505 is inserted into the positioning groove 502, the second flange ring 504 is rotated, so that the end of the positioning plate 505 is rotated and inserted into the receiving groove 503. Then, the connection hole 507 on the side wall of the first flange ring 501 is aligned with the connection hole 507 on the side wall of the second flange ring 504. The bolts are screwed in to improve stability and prevent loosening and separation. The sealing ring 506 effectively improves the sealing performance and prevents fluid leakage.

[0037] Next, in order to prevent the valve core 405 from detaching, specifically, the output end of the hydraulic cylinder 402 is slidably connected to the top of the valve body 1, and the cross-section of the limiting ring 404 is inverted L-shaped. The inverted L-shaped limiting ring 404 helps to limit the moving plate 403 and prevent the limiting ring 404 from detaching from the valve core 405 and affecting the use.

[0038] Meanwhile, to prevent fluid from flowing out from multiple second connectors 3 simultaneously, specifically, the size of the through hole 406 matches the inner diameter of the second connector 3, and the distance between the through hole 406 and the bottom of the valve core 405 is greater than the height difference between the two second connectors 3. Because the distance between the through hole 406 and the bottom of the valve core 405 is greater than the height difference between the two second connectors 3, it is convenient for the valve core 405 to move to align the through hole 406 with the higher second connector 3. The bottom of the valve core 405 can block the lower second connector 3, thus preventing fluid from flowing out from multiple second connectors 3 simultaneously and affecting the use of the reversing valve.

[0039] Furthermore, to facilitate fluid flow, specifically, the two second connecting pipes 3 are inclined at the same angle and in the same direction. The valve core 405 has an opening at the bottom. The two second connecting pipes 3, which are inclined at the same angle and in the same direction, help to reduce the impact force of the fluid received by the oblique reversing valve. The valve core 405 with the bottom opening facilitates the formation of a fluid flow channel with the first connecting pipe 2.

[0040] It is worth noting that, in order to improve the movement stability of the positioning groove 502, the positioning plate 505 has an L-shaped cross-section. The size and position of the end of the positioning plate 505 match the size and position of the receiving groove 503. By matching the size and position of the end of the positioning plate 505 with the receiving groove 503, the L-shaped positioning plate 505 can be installed more securely, avoiding loosening that could affect the connection between the oblique reversing valve and the external pipeline.

[0041] Finally, to improve sealing performance, the sealing ring 506 is made of silicone rubber. The connecting holes 507 on the side wall of the first flange ring 501 and the connecting holes 507 on the side wall of the second flange ring 504 are staggered. The silicone rubber sealing ring 506 provides a good sealing effect. The staggered connecting holes 507 make it easy for the second flange ring 504 to rotate and be aligned with the bolts for fixing.

[0042] In addition, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this utility model does not involve improvements to the internal structure and methods.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] Hydraulic cylinder 402: HS01-210L.

[0045] Combination Figures 1-5 The following is a specific usage process of a slanted reversing valve according to this embodiment:

[0046] 1: According to the actual use, start the hydraulic cylinder 402 to drive the moving plate 403 to move, thereby moving the limit ring 404 and driving the valve core 405 to move. Through the guide block 408, the valve core 405 is driven to rotate along the spiral groove 407, thereby moving the through hole 406 and rotating it to another second pipe 3. The fluid input from the first pipe 2 flows from the valve core 405 into the other second pipe 3.

[0047] 2: Connect the second flange ring 504 at one end of the external pipeline to the first flange ring 501. After the positioning plate 505 is inserted into the positioning groove 502, rotate the second flange ring 504 so that the end of the positioning plate 505 is rotated and inserted into the receiving groove 503. Then, align the connecting hole 507 on the side wall of the first flange ring 501 with the connecting hole 507 on the side wall of the second flange ring 504 and screw in the bolt.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
