Embodiment 1

[0021] Such as figure 1 As shown, a hydraulic regulating valve device of the present invention includes a three-way valve body, the first channel 1 on the left side of the three-way valve body and the second channel 2 on the right are on the same horizontal line, and the third channel 8 is connected to the first channel 1 intersects with the second channel 2 and communicates vertically. A spool seat 13 is installed at the junction of the third channel 8 and the first channel 1 and the second channel 2. A spool 3 is installed on the spool seat 13. The bottom surface of the spool 3 The contact surface with the valve core seat 13 is in sealing contact, and the inside of the valve core 3 is processed with a "T"-shaped sixth channel 12 that penetrates through each other; the outlets of the two channels on the same straight line of the sixth channel 12 are installed with fan-shaped valves with the same shape. The first blade 4 and the second blade 5 are provided with a fourth passag...

Embodiment 2

[0024] Such as image 3 As shown, on the basis of Embodiment 1, the outlet of the third passage 8 is connected to the pressure storage tank 10, and when the first vane 4 and the second vane 5 rotate to adjust the pressure, the hydraulic oil discharged from the third passage 8 can be recovered, A piston 16 is installed at the bottom of the pressure storage oil tank 10. When the pressure storage oil tank 10 is filled with hydraulic oil, the hydraulic oil pushes the piston 16 to compress the second spring 17, converting the pressure of the hydraulic oil into the elastic force of the second spring 17. When the internal pressure of the first channel 1 and the second channel 2 are unbalanced, the piston 16 pushes the hydraulic oil to adjust the pressure in the pipeline.

Embodiment 3

[0026] On the basis of Embodiment 2, a rubber pad is installed on the inner wall of the groove 9. When the first blade 4 and the second blade 5 are in contact with the rubber pad, the rubber pad can better connect the fourth passage 6 and the fifth passage 7 The seal can prevent the hydraulic oil from flowing out through the fourth channel 6 and the fifth channel 7 when the hydraulic system is working, thereby reducing the pressure change in the channel.

Abstract

The invention belongs to the technical field of hydraulic equipment, and particularly discloses a hydraulic regulating valve device. The device comprises a three-way valve body and a valve core, the three-way valve body is provided with a first channel, a second channel and a third channel, wherein the first channel and the second channel are arranged on the same straight line, and the third channel is intersected with the first channel and the second channel and is perpendicular to the first channel and the second channel; and a valve core seat is arranged at the joint of the third channel and the first channel and the second channel, the valve core is arranged on the valve core seat, the bottom of the valve core is in sealing contact with the valve core seat, the valve core is provided with a first blade and a second blade which are the same in shape, and the first blade and the second blade are each provided with a channel communicating with the valve core. The device is mainly applied to a hydraulic pipeline and solves the problem that the pressure in the hydraulic pipeline cannot be automatically adjusted.

Description

technical field [0001] The invention belongs to the technical field of hydraulic equipment, and specifically discloses a hydraulic regulating valve device. Background technique [0002] In hydraulic equipment, hydraulic valves are commonly used to adjust the pressure in the hydraulic device. Through the adjustment of hydraulic valves, the adjustment function can be realized quickly and accurately. The use of hydraulic valves can ensure the stability of the transmission force of the hydraulic system. [0003] However, in the process of using the hydraulic valve, manual adjustment of the hydraulic valve is prone to action delay, which can lead to increased action range during the working process of the hydraulic equipment, and ultimately fail to achieve the effect of operation. In the prior art, there are many types of hydraulic valves and complex structures, which are easy to be damaged during use, and the processing cost is high, which makes it difficult for users to choose....
