Embodiment Construction

[0014] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0015] Such as figure 1 As shown, a stacked sequence valve includes a valve body 1 with a certain thickness, a valve core 3 is arranged in the valve body 1, and a pressure detection port 2 is arranged on one side of the valve body 1 (the left side in the figure). The other side of the valve body 1 (the right side in the figure) is provided with a spring 7, and the tail of the spring 7, that is, the right side of the spring 7, is provided with an adjusting screw 8. The spring 7 force of the spring 7 can be adjusted by adjusting the screw 8, thereby controlling The status of each outlet. The spring 7 is arranged on one side of the valve body 1 thro...

Abstract

The invention discloses a stacked sequence valve which comprises a valve body in certain thickness. A valve core is arranged in the valve body. The stacked sequence valve is characterized in that a pressure detection port is arranged on one side of the valve body, a spring is arranged on the other side of the valve body, an adjusting screw is arranged at the tail of the spring, the spring is arranged on one side of the valve body through a valve cover outside, a sealing block is fixedly arranged on the end portion of the spring, an oil inlet is arranged at the bottom of the valve body, an axial hole is formed between the oil inlet and the pressure detection port, at least two oil outlets are arranged at the top of the valve body and connected through a connecting passage, and the sealing block can be hermetically inserted into the connecting passage and can move along the same. Opening or closing states of the oil outlets are controlled through the valve core and the spring respectively, and the stacked sequence valve is simple in structure, low in cost and small in control deviation.

Description

technical field [0001] The invention relates to a stacked sequence valve. Background technique [0002] Sequence valve is a valve that controls the action sequence of actuators according to the pressure of the circuit in a system with more than two branch circuits. Among them, the superimposed sequence valve is a commonly used sequence valve. [0003] When the conventionally designed superimposed sequence valve has multiple oil outlets, the valve core controls the opening or closing state of each oil outlet. This structure leads to a complex sequence valve structure, high cost, and large control deviation. Contents of the invention [0004] In view of the above problems, the present invention provides a superimposed sequence valve, which controls the opening or cutting state of each oil outlet through the valve core and spring respectively, with simple structure, low cost and small control deviation. [0005] In order to achieve the above-mentioned technical purpose and a...
