Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, a hydraulic valve device is characterized in that: it includes a hydraulic valve, the hydraulic valve has a housing 1, on the housing there is a first passage 2 through the left and right, the first passage has a left port 3 and Right port 4, there is a second channel 5 that penetrates up and down on the housing, the first channel and the second channel intersect to form a cavity with a "ten" structure, and the second channel is under the "ten" structure The lower passage 6 has an electromagnet 7 above the second passage, a spool 8 that can slide up and down along the second passage below the electromagnet, a first spring 9 supporting the spool below the spool, and a spring 9 below the second passage. The exit of lower channel 6;

[0018] In the middle of the spool is a thinning neck portion 11. There is a sealing ring 12 below the s...

Abstract

The invention relates to a hydraulic device which comprises a hydraulic valve. The hydraulic valve is provided with a shell. The shell is provided with a first channel penetrating through the shell horizontally. The first channel is provided with a left opening and a right opening. The shell is provided with a second channel penetrating through the shell vertically. The first channel and the second channel intersect with each other to form a cavity of a cross structure. The portion, below the cross structure, of the second channel is provided with a lower channel. An electromagnet is arranged above the second channel. A valve element capable of sliding along the second channel vertically is arranged below the electromagnet. A first spring for supporting the valve element is arranged below the valve element. An outlet of the lower channel is formed below the second channel. The middle of the valve element is the neck portion which becomes thinner. A sealing ring matched with the lower portion of the second channel is arranged below the valve element. A side seam is arranged below the sealing ring. The hydraulic device has the advantages that whether the lower channel and the first channel are communicated with each other or not can be controlled by controlling the electromagnet, and the hydraulic device further has the advantages of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to a hydraulic valve device, which is widely used in some machine equipment, such as bending machines, cutting machines and the like. Background technique [0002] In the prior art, there are many kinds of hydraulic valves, but they have the disadvantages of complex structure and high cost, which makes the hydraulic valves easily damaged, and the price is unacceptable to users. Contents of the invention [0003] The object of the present invention is to provide a hydraulic valve device with simple structure and low cost to solve the above disadvantages. [0004] The technical solution of the present invention is realized in the following way: a hydraulic valve device, which is characterized in that it includes a hydraulic valve, the hydraulic valve has a housing, and on the housing there is a first passage through the left and right, the first passage It has a left port and a right port, and there is a second channel that penet...
