Description

Technical Field

[0001] The invention relates to the technical field of hydraulic and pneumatic control, and in particular to a curvature continuous valve with adjustable flow channel. Background Art

[0002] Valves are key components in direct contact with fluids in hydraulic and pneumatic control systems. They control the flow rate and pressure of the fluid to achieve functions such as cutoff, regulation, flow diversion, pressure stabilization and pressure relief. When the fluid medium passes through the valve, its energy loss is closely related to the flow state. Different valve internal structures will lead to differences in fluid flow states, resulting in laminar flow and turbulence in different states, causing unnecessary energy loss of the fluid. Therefore, the valve internal structure has a significant impact on the flow state of the fluid medium and the stability and economy of the hydraulic and pneumatic control system.

[0003] The existing valve structures on the market do not have continuous curvature, which will lead to unnecessary energy loss. The flow channel angle in the existing valve is a fixed value and cannot be adjusted according to the working conditions. The valve's adaptability to working conditions is greatly limited. In addition, the set pressure adjustment of the existing valve depends on the set spring, and the adjustable range is small. Summary of the invention

[0043] Embodiment 1:

[0044] A continuous curvature valve with adjustable flow channel, such as Figure 1 , Figure 2 As shown, it is composed of an air pump module 100, a valve body module 200, a connection module 300 and a flow channel adjustment module 400.

[0045] In this embodiment, the air pump module 100 is composed of an air pump power interface 110, an air pump body 120 and an air pump output hole 130, and the air pump module is fixed above the valve top 210 by threaded connection. The valve body module 200 includes a valve top 210, a base 220, a valve core 230 and a valve bottom 240. The valve top 210 is fixed above the base 220 by bolt connection, and the valve bottom 240 is fixed below the base by bolt connection. The connection module 300 includes an upper gasket 310, a lower gasket 311, a bolt 1 321, a bolt 2 322, a bolt 3 323, and a bolt 4 324.

[0046] In this embodiment, the flow channel adjustment module 400 includes a right flow channel 410, a left flow channel 420, a right flow channel adjustment module 430, and a left flow channel adjustment module 440; the right flow channel adjustment module 430 includes a right adjustment slider 431, a right cylinder rod 432, a right cylinder body 433, a right cylinder air inlet 434, and a right cylinder air outlet 435; the right flow channel adjustment module 430 is fixed to the base 220 by bolt connection, and a ball joint is provided on the top of the right cylinder rod 432, which is connected to the right adjustment slider 431 through the ball joint, and the right adjustment slider 431 is connected to the right flow channel 410. The right cylinder rod 432 drives the right adjustment slider 431 to slide, so as to adjust the angle of the right flow channel 410. The left flow channel adjustment module 440 includes a left adjustment slider 441, a left cylinder rod 442, a left cylinder body 443, a left cylinder air inlet 444, and a left cylinder air outlet 445. The left flow channel adjustment module 440 is fixed to the base 220 by bolt connection. A ball joint is provided on the top of the left cylinder rod 442, which is connected to the left adjustment slider 441 through the ball joint. The left adjustment slider 441 is connected to the left flow channel 420. The left cylinder rod 442 drives the left adjustment slider 441 to slide, so as to adjust the angle of the left flow channel 420.

[0047] Embodiment 2:

[0048] A continuous curvature valve with adjustable flow channel, such as Figure 3 , Figure 4 As shown, at this time, the adjustable curvature continuous valve of the flow channel is in a working state. Taking the adjustment process of the right flow channel 410 as an example, the technical solution of the present invention is explained. The adjustment technical solution of the left flow channel 420 is similar to that of the right flow channel 410 and will not be repeated here.

[0049] In this embodiment, the air pump module 100 performs the inflating and deflation operations in the valve through the air pump output hole 130, thereby realizing the preset set pressure. When the fluid medium pressure below the valve core 230 exceeds the set pressure, the valve core 230 moves upward under the pressure, the curvature continuous valve opens, and the valve enters the working state.

[0050] At this time, the right flow channel angle can be adjusted according to the working conditions to reduce the pressure loss when the fluid medium flows out. The specific technical solution is that the external control module sends a signal to the flow channel adjustment module 400, and the right flow channel adjustment module 430 starts to work, and the pressure in the right cylinder body 433 is increased through the cooperation of the right cylinder air inlet hole 434 and the right cylinder air outlet hole 435, thereby pushing the right cylinder rod 432 to move upward, and the right cylinder rod 432 transmits the movement to the right adjustment slider 431 through the ball joint, and the right adjustment slider 4 31 cooperates with the dovetail groove 413 of the right flow channel to realize linear motion, and the ball joint ensures that the orientation of the right adjusting slider 431 remains unchanged, thereby pushing the right flow channel 410 to move upward. Since the spherical surface 411 of the right flow channel is always matched with the spherical surface 221 of the base, the upward movement of the right flow channel 410 is converted into a rotational movement around the center of the spherical surface 411 of the right flow channel, thereby realizing the adjustment of the angle of the right flow channel 410 to adapt it to the outflow angle of the fluid medium, reduce pressure loss, and improve the working efficiency of the present invention.

[0051] Embodiment 3:

[0052] A continuous curvature valve with adjustable flow channel, such as Figure 5 It is a side view of the present invention, taking the working process of the right flow channel adjustment module 430 as an example to illustrate the technical solution of the present invention. The technical solution of the left flow channel adjustment module 440 is similar to that of the right flow channel adjustment module 430, which will not be repeated here.

[0053] In this embodiment, the right cylinder rod 432 is connected to the right adjusting slider 431 through a ball joint structure. When the relative position (angle) of the right cylinder rod 432 and the right adjusting slider 431 changes, the ball joint structure ensures that the right cylinder rod 432 and the right adjusting slider 431 are always connected; the right adjusting slider 431 is connected to the right flow channel 410 through the right flow channel dovetail groove 413, forming a linear motion pair, ensuring that the right adjusting slider 431 can only make linear motion along the right flow channel dovetail groove 413.

[0054] In this embodiment, when the right flow channel adjustment module 430 starts to work, the pressure in the right cylinder body 433 is increased through the cooperation of the right cylinder air inlet hole 434 and the right cylinder air outlet hole 435, thereby pushing the right cylinder rod 432 to move upward, and the right cylinder rod 432 pushes the right adjustment slider 431 through the ball joint structure. Since the right adjustment slider 431 can only move in a straight line along the right flow channel dovetail groove 413, that is, the right adjustment slider 431 is limited in the direction of its own force, and then the right adjustment slider 431 pushes the right flow channel 410 to move upward, thereby realizing the adjustment of the angle of the right flow channel 410. During the upward movement of the right flow channel 410, the direction of the right flow channel dovetail groove 413 changes. Since the right adjusting slider 431 can only move linearly along the right flow channel dovetail groove 413, the direction of the right adjusting slider 431 also changes. Thanks to the ball joint structure, although the relative position (angle) between the right cylinder rod 432 and the right adjusting slider 431 changes, a reliable connection is still maintained to ensure the transmission function.

[0055] In this embodiment, when the right adjustment slider 431 makes a linear motion along the right flow channel dovetail groove 413 away from the base 220, the right flow channel 410 makes a counterclockwise rotation motion with the center of the right flow channel spherical surface 411 as the center, thereby increasing the angle of the right flow channel 410; when the right adjustment slider 431 makes a linear motion along the right flow channel dovetail groove 413 close to the base 220, the right flow channel 410 makes a clockwise rotation motion with the center of the right flow channel spherical surface 411 as the center, thereby reducing the angle of the right flow channel 410.

[0056] Embodiment 4:

[0057] A continuous curvature valve with adjustable flow channel, such as Figure 6 , Figure 7 As shown, the base 220 is provided with a base spherical surface 221 and a base curvature continuous surface 222 ; the right flow channel 410 is provided with a right flow channel spherical surface 411 , a right flow channel curvature continuous surface 412 and a right flow channel dovetail groove 413 .

[0058] In this embodiment, the base spherical surface 221 cooperates with the right flow channel spherical surface 411. The use of spherical surfaces for cooperation can effectively ensure the reliability and sealing of the connection between the right flow channel 410 and the base 220 during rotation; the inner envelope surface of the base spherical surface 221 is larger than the outer contour of the right flow channel spherical surface 411, which can ensure that the right flow channel 410 can form a consistent cooperation with the base 220 at any rotation angle. The base curvature continuous surface 222 and the right flow channel curvature continuous surface 412 together constitute the outflow channel of the fluid medium in the valve, and are not affected by the rotation angle of the right flow channel 410, which ensures that the fluid medium is always in the valve structure with continuous curvature, reduces the pressure loss in the valve, reduces the cost, and improves the working efficiency of the present invention.

[0059] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
