Pneumatic switchproduct description:

It is mainly used for track switching in mines and railways. The cost of pneumatic switch is relatively reasonable and labor-saving.

Pneumatic switch product parameters:

This product is a mining pneumatic (turnout) switch, with dimensions of 600mm in length, 550mm in width, and 140mm in height.

Used on 22Kg/m; 24Kg/m; 30Kg/m turnouts, track gauge 600mm/900mm, air pump is Ф80X150.

Pneumatic switchinstallation method:

During installation, connect the pneumatic switch device to the connecting rod at the switch point rail, find the appropriate position, and fix the pneumatic switch device on the sleeper firmly and reliably. Then fix the white operating box to the appropriate position (the operating box is equipped with a pressure regulating valve and a conversion valve), then connect the blue high-pressure air bag to the air source, and connect the other end to the air inlet of the operating box to test the pressure. When using the pressure regulating valve, first pull out the black rotating cap about 2-3mm, rotate it clockwise to increase the pressure to 0.4-0.6mPa, and then press the rotating cap back. Then connect the other two air bags to the conversion valve, and the other end to the cylinder of the pneumatic (switch) switch (one is connected to the intake air and the other is connected to the return air). The conversion valve handle is divided into three positions: left, middle and right. When the handle is on the left or right, the pneumatic switch device is open or closed, and when the handle is in the middle position, it is locked.

Basic parameters of pneumatic switch:

Scope of application: Change the direction of mine car at the fork of mine car

Buffer stroke: 32mm

Pneumatic type: piston type

Cylinder pipe diameter: G3/8

Piston rod diameter: 25mm

Dimensions: 600*800*500mm

Cylinder diameter: 80mm

Weight: 48kg

Working principle of pneumatic switch:

The main air duct of the mine tunnel is connected to the check valve and pressure vessel; one end of the two-position four-way valve is connected to the pressure vessel, and the other end is connected to the cylinder. The cylinder body must be reliably fixed on one side of the track to prevent loosening and hinder vehicle driving. The length of the linkage rod should be appropriate (adjustable bolt rod, firmly connected to the cylinder body and track.
