Problems solved by technology

[0003] When the oil flows through the spool valve, the size and direction of the oil velocity change, and the sharp change of its momentum will not only cause the pressure of the local oil circuit to rise sharply, resulting in impact noise, but also affect the maneuverability of the spool valve and interfere with The signal causes the movement of the spool to be disordered, thus affecting the stability and reliability of the spool valve
When switching the oil circuit, due to the existence of static friction between the valve core and the valve seat, the action of the valve core will be later than the signal control, resulting in insensitive switching

Embodiment 1

[0041] See how Figure 1-6 , the invention discloses a control valve with low energy consumption and high frequency response, comprising a valve body 1, a valve core 2 is arranged in the valve body 1, one end of the valve core 2 is connected with a first valve core control mechanism 9, and the other end is connected with a rotating motor 6 connections.

[0042] The left and right sides of the valve body 1 are respectively provided with through holes, and the through hole on the left side is used to connect one end of the first spool control mechanism 9 with one end of the spool 2 located in the valve body 1, and the first spool 2 control mechanism 9 Used to control the left and right movement of the spool 2.

[0043] The bottom of the first spool control mechanism 9 is installed on the base 3 , and one end of the base 3 is connected to the side of the valve body 1 . The frame 3 is used to support the first spool control mechanism 9 .

[0044] Such as figure 1 As shown, one...

Embodiment 2

[0067] In the second aspect, the present application also discloses a method for controlling a control valve with low energy consumption and high response, and the specific steps are as follows:

[0068] S1: input the oil into the cavity of the valve body 1 through the first curved channel 13 of the valve body 1;

[0069] S2: The rotary motor 6 drives the spool 2 to rotate;

[0070] S3: The second spool control mechanism 10 moves to the side where the first spool control mechanism 9 is connected to the spool 2 by pushing the rotating motor 6; the first spool control mechanism 9 pushes the spool 2 to the second spool control mechanism The side where 10 is located moves; the oil passes through the second curved channel 14 on the side of the spool 2 close to the first spool control mechanism 9 to control the movement of the actuator connected to the second curved channel 14;

[0071] S3: The first spool control mechanism 9 moves to the side where the second spool control mechani...

Abstract

The invention relates to the technical field of control valves, in particular to a low-energy-consumption and high-frequency-response control valve. The low-energy-consumption and high-frequency-response control valve comprises a valve body, wherein a valve element is arranged in the valve body; one end of the valve element is connected with a first valve element control mechanism, the other end of the valve element is connected with an output shaft of a rotating motor, and the rotating motor is slidably connected to a motor base through a guide rail on the motor base; a first curve flow channel and a second curve flow channel are arranged at the positions, located below the valve element, of the valve body, and automatic adjusting blade sets are symmetrically arranged on the two sides of the upper portion of the first curve flow channel in the horizontal direction; the automatic adjusting blade sets comprises blades, the bottom faces of the blades are fixed to rotating shafts, and the rotating shafts are connected to the valve body in a hinged mode and used for driving the blades to rotate relative to the valve body; and one ends of springs are connected to the blades, and the other ends of the springs are fixedly connected to the valve body. The streamline flow channels are adopted inside the valve body so that fluid flow resistance can be reduced, and fluid pressure loss is reduced; and the valve element rotates slowly, so that reversing resistance is lower, response is faster, and control is more sensitive.

Description

technical field [0001] The present disclosure relates to the technical field of control valves, in particular to a control valve with low energy consumption and high frequency response. Background technique [0002] The reversing valve is a valve that uses the difference in the relative position between the valve core and the valve body to change the on-off relationship of each oil port on the valve body, thereby changing the direction of the liquid flow. [0003] When the oil flows through the spool valve, the size and direction of the oil velocity change, and the sharp change of its momentum will not only cause the pressure of the local oil circuit to rise sharply, resulting in impact noise, but also affect the maneuverability of the spool valve and interfere with The signal causes the movement of the spool to be disordered, thus affecting the stability and reliability of the spool valve. When switching the oil circuit, due to the existence of static friction between the ...
