Branch valve in pneumatic conveying system
? ? ?There is a particularly important device in pneumatic conveying, which is the switching device of the pipeline material in the conveying system. It can change the direction of the material during conveying, and this device must have very good reliability.Pneumatic shunt valveIt is a plug type structure with reliable sealing and flexible reversing, which can transport powders, particles, and liquid materials.
In terms of control, a gear rack swing cylinder is used to drive the direction change of the plug, and a magnetic switch is installed to indicate and control the direction change of the cylinder; The main control is the electromagnetic directional valve that controls the intake and exhaust to achieve directional control. There are two models and 16 specifications of this shunt valve, with diameters ranging from millimeters. The pressure range is+1.0MPa, the temperature range is ℃, and the materials are carbon steel, stainless steel, and aluminum alloy, which can meet the requirements of different industries, media, and working conditions. The pneumatic shunt valve is shown in Figure 1:

Protection of oil sources:
1. According to the operating condition of the machine and the service life of the oil, regularly replace the oil suction filter and filter element, and replace the hydraulic oil.
2. Regularly check whether there is any oil leakage at the host and oil source. If oil leakage is found, the sealing ring or combination gasket should be replaced in a timely manner;
3. When not conducting experiments for a long time, pay attention to turning off the power supply of the host. If the machine is in standby mode, the switch should be set to the "load" position. If the switch is set to the "fast reverse" position, the electromagnetic reversing valve will remain powered on, which will affect the service life of the equipment.
? ? ?Branch valves are a very important part of pneumatic conveying. If inferior branch valves are used, problems may occur during the operation of the pneumatic conveying system, which may lead to pipe blockage or even paralysis of the entire line. Therefore, it is recommended that everyone choose to use themShandong Juheng Environmental Protection Equipment Co., LtdThe pneumatic conveying equipment manufactured by us is a strong manufacturer with stable operation and one-year warranty.
