Problems solved by technology

[0003] At present, the existing internal structure of the valve on the market does not have continuous curvature, which will lead to unnecessary energy loss; and the angle of the flow channel in the existing valve is a fixed value, and the angle of the flow channel in the valve cannot be adjusted according to the working conditions. In addition, the set pressure adjustment of the existing valve depends on the set spring, and the adjustable range is small

Embodiment 1

[0044] A curvature continuous valve with adjustable flow path, 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 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 through screw connections. The valve body module 200 includes a valve top 210 , a base body 220 , a valve core 230 and a valve bottom 240 . The valve top 210 is fixed above the base body 220 by bolts, and the valve bottom 240 is fixed below the base body by bolts. The connection module 300 includes an upper washer 310 , a lower washer 311 , a bolt one 321 , a bolt two 322 , a bolt three 323 , and a bolt four 324 .

[0046] In this embodiment, the flow channel adjustment module 400 includes a right flow channel 410, a left flow channel 42...

Embodiment 2

[0048] A curvature continuous valve with adjustable flow path, such as image 3 , Figure 4 As shown, the curvature continuous valve with adjustable flow path is in working state at this time. Taking the adjustment process of the right flow path 410 as an example, the technical solution of the present invention is described. The adjustment technical solution of the left flow path 420 is similar to that of the right flow path 410. I won't repeat them here.

[0049] In this embodiment, the air pump module 100 charges and deflates the valve through the air pump output hole 130 , so as to realize the preset of the set pressure. When the pressure of the fluid medium under the spool 230 exceeds the set pressure, the spool 230 moves up under the pressure, the curvature continuous valve opens, and the valve enters the working state.

[0050] At this time, the angle of the right channel can be adjusted according to the working conditions to reduce the pressure loss when the fluid med...

Embodiment 3

[0052] A curvature continuous valve with adjustable flow path, such as Figure 5 Shown 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, and will not be repeated here .

[0053] In this embodiment, the right cylinder rod 432 is connected to the right adjustment slider 431 through a ball joint structure. When the relative position (angle) between the right cylinder rod 432 and the right adjustment slider 431 changes, the ball joint structure ensures that the right cylinder The rod 432 is always connected with the right adjusting slider 431; the right adjusting slider 431 is connected with the right runner 410 through the right runner dovetail groove 413, forming a linear motion pair, ensuring that the ...

Abstract

The invention discloses a curvature continuous valve with an adjustable flow channel. The curvature continuous valve comprises an air pump module, a valve body module, a connecting module and a flow channel adjusting module; the air pump module comprises an air pump power interface, an air pump main body and an air pump output hole; the valve body module comprises a base body, a valve top, a valve bottom and a valve element; the connecting module comprises an upper gasket, a lower gasket, a valve body fixing bolt and an air cylinder fixing bolt; a flow channel adjusting module comprises a right flow channel adjusting module and a left flow channel adjusting module; and the air pump module is connected to the valve top through the valve body fixing bolt, and the flow channel adjusting module is connected to the base body through the air cylinder fixing bolt. The inclination angles of a right flow channel and a left flow channel in the valve are adjustable, and the angles of the right flow channel and the left flow channel can be adjusted according to the flowing-out angle of a fluid medium so as to facilitate flowing-out of the fluid medium; and the air pump module is adopted to replace an existing setting spring to achieve adjustment of the setting pressure, and the adjustable range of the setting pressure is larger.

Description

technical field [0001] The invention relates to the technical field of hydraulic and pneumatic control, in particular to a curvature continuous valve with adjustable flow path. Background technique [0002] The valve is a key component in direct contact with the fluid in the hydraulic and pneumatic control system. By controlling the flow rate and pressure of the fluid, it can realize the functions of cutting, regulating, diverting, stabilizing and releasing the pressure. 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 the fluid flow state, resulting in laminar flow and turbulent flow in different states, resulting in unnecessary energy loss of the fluid. Therefore, the internal structure of the valve has a significant impact on the flow state of the fluid medium and the stability and economy of the hydraulic and pneumatic control systems. [0003] At present...
