Pneumatic valve body

Abstract

The invention discloses a pneumatic valve body. The pneumatic valve body comprises a shell, at least two cavities communicated with each other are arranged in the shell, communicating pipes used for being inserted into an external air path are arranged on the cavities in a communicating mode, air outlet holes distributed in an array mode are formed in the shell, a circuit piece is arranged in the shell, at least two coil assemblies are arranged on the circuit piece, a valve moving assembly is arranged on each coil assembly, a magnetism isolating film is arranged between each coil assembly and the corresponding valve moving assembly, each valve moving assembly is attracted and separated through power-on and power-off of the corresponding coil assembly, air discharging of the air outlet holes is controlled, the cavities correspond to the coil assemblies in a one-to-one mode, and more air outlet holes are formed in a valve body base per unit length. According to the valve body, the at least two coil assemblies and corresponding air holes are arranged in the shell, the installation space of the pneumatic valve body is reduced, more air outlet holes can be formed in the base of unit length, the installation number of the pneumatic valve body is reduced, and the installation efficiency is improved.

Description

technical field [0001] The invention relates to the field of valve bodies, in particular to a pneumatic valve body. Background technique [0002] In the field of color sorting machines, multiple nozzles integrated in the nozzle blow air to change the running track of the material to be selected, so as to realize the sorting of materials. In the color sorting machine, the fluid access part, solenoid valve and nozzle part Connect in sequence by using external pipes (such as hoses) at the interface. The setting of the external pipes will increase the transmission line of the fluid (in the application of the color sorter, the fluid is compressed gas), which will cause the fluid pressure to be unstable. . In the application number: 202021882754.1, a spraying device is disclosed. The spraying device is installed on the base to screen the products. The length of the base is limited during use. How to set more air outlets on the base per unit length ; At the same time, according t...
