Embodiment Construction

[0020] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0021] Such as Figure 1-3 As shown, a pneumatic proportional adjustment device based on a solenoid valve array includes an upper end cover 2, a main valve body 18, a lower end cover 14, an intake solenoid valve array, an exhaust solenoid valve array, a first quick connector 11, and a second Quick connector 12, muffler 10, pressure sensor 5, pressure sensor pressing piece 4, circuit board 6, rubber seal 13 and other components. The left and right surfaces of the main valve body 18 are respectively installed with an intake solenoid valve array and an exhaust solenoid valve array for charging and exhausting the air cavity 25. The intake solenoid valve array includes a large diameter solenoid valve 15, a middle There are three types of solenoid valves, 16 and 17 small diameter solenoid valves. Each solenoid valve is composed of two and a total of six. The exhaus...

Abstract

The invention discloses a pneumatic proportion regulator based on an electromagnetic valve array, which comprises a main valve body, an upper end cover, a lower end cover, an air inlet electromagnetic valve array and an air outlet electromagnetic valve array, wherein an air cavity, an air inlet air path and an exhaust air path which are mutually separated and independent are arranged in the main valve body, the top of the main valve body is provided with a pressure sensor and a circuit board, in addition, the upper end cover is arranged on the top of the main valve body for accommodating the pressure sensor and the circuit board, the bottom of the main valve body is provided with the lower end cover, the left side and the right side of the main valve body are respectively provided with the air inlet electromagnetic valve array and the air outlet electromagnetic valve array, and the front side of the main valve body is provided with a first interface and a second interface which are respectively communicated with the air inlet air path and the air cavity. The pneumatic proportion regulator has the advantages that the control is flexible and variable, the fault redundancy is realized, the large-through-diameter and high-flow-rate air supply is realized, and simultaneously, the ideal response performance can be ensured.

Description

Technical field [0001] The invention belongs to the technical field of pneumatics, and relates to a pneumatic proportional adjustment device, in particular a pneumatic proportional adjustment device based on an electromagnetic valve array. Background technique [0002] At present, the response speed of large-diameter solenoid valves on the market is generally slow. For pneumatic solenoid valves, the smaller the diameter, the faster the response speed. Although the response speed of the medium and small diameter solenoid valve is relatively fast, the medium and small diameter solenoid valve cannot meet the requirement of large flow. In engineering applications, there is an urgent need for a pneumatic proportional adjustment device that can achieve large flow supply and exhaust, and at the same time have good response performance. Summary of the invention [0003] The purpose of the present invention is to provide a pneumatic proportional adjustment device based on a solenoid valve...
