Embodiment

[0014] Such as figure 1 As shown, a hydraulic oil control valve includes a valve body 1, and four oil passages are arranged in the valve body 1, which are respectively the first oil passage 2, the second oil passage 3, the third oil passage 4 and the fourth oil passage 5. The four oil passages are connected through the middle oil passage 6, and the middle oil passage 6 is equipped with a control and adjustment device. The control and adjustment device includes the left valve block 7, the side valve block 8, the middle valve block 9 and the right valve block 10. The position of the side valve block 8 is fixed, and the side valve block 8 is provided with a side valve block stopper 11, and the middle valve block 9 is provided for movement, and the middle valve block 9 is provided with a stopper 11 used in conjunction with the side valve block. The stopper 12 of the middle valve block, the middle of the middle valve block 9 is provided with a passage 13, the left valve block 7 is ...

Abstract

The invention provides a hydraulic oil control valve which comprises a valve body, wherein four oil channels are arranged in the valve body, and communicate with one another through a middle oil channel; a control regulating device is arranged in the middle oil channel, and comprises a left valve block, a side valve block, a middle valve block and a right valve block; the position of the side valve block is fixed; a side valve block stopper is arranged on the side valve block; the middle valve block is arranged movably; a middle valve block stopper cooperatively used with the side valve block stopper is arranged on the middle valve block; a through channel is arranged at the middle of the middle valve block; the left valve block is arranged movably; a through channel stopper is arranged on the side, close to the side valve block, of the left valve block; the position of the right valve block is fixed; and a strip groove and a movable stopper are arranged in the right valve block. The hydraulic oil control valve has the advantages that the oil channels are simplified; the quantity of elements is small; the communication among and the blocking control of the different oil channels can be simply achieved as required; and the actions of an actuating mechanism can be switched over.

Description

technical field [0001] The invention belongs to the hydraulic field, in particular to a hydraulic oil control valve. Background technique [0002] At present, ordinary hydraulic valves can only control the pressure and flow of the liquid flow at a fixed value through pre-adjustment, and then make the actuator act. Pressure and flow parameters can be adjusted or continuously controlled, which cannot be realized with ordinary hydraulic valves. Therefore, there is an urgent need for a simple in design, convenient and practical hydraulic oil control valve. Contents of the invention [0003] The invention proposes a hydraulic oil control valve, which solves the problem in the prior art that ordinary hydraulic valves cannot realize continuous control of oil circuit switching. [0004] The technical solution of the present invention is realized as follows: a hydraulic oil control valve, including a valve body, four oil passages are arranged in the valve body, which are respecti...
