Powder system analysis of powder butterfly system

When we talk about the powder system analysis of the powder butterfly valve, we first analyze some characteristics and characteristics of the powder butterfly valve, and have a new understanding of the powder butterfly valve in many directions.

The powder butterfly valve is a valve used to quickly cut off solid materials, such as cement, stone powder, etc. Let's take a look at the powder system of the powder butterfly valve. The powder butterfly valve is composed of a pneumatic piston actuator and a butterfly valve body: the structure is simple, the volume is small, the weight is light, the cost is low, and the pneumatic flange valve is particularly remarkable. It is installed in the high-altitude dark channel and passes through the two-position five-way solenoid valve. The control operation is convenient, and the flow medium can also be adjusted.

The powder butterfly valve is mainly used for the agitation of the powder or the like and the uniform mixing in the powder.

The butterfly valve is used for the control of solid materials, and is often used as a discharge valve at the bottom of the tank, such as a tank bottom of a cement tank or a stone powder tank, for discharging and quick cutting. Because most of the dust materials contain large or small particles, the wear of the valve sealing surface is unquestionable. If the selection is improper, the service life of the valve will be greatly reduced, or the valve leakage will be caused quickly, which will affect the continued use. The working principle of the powder butterfly valve: the powder butterfly valve is opened and closed with a circular disc rotating with the valve, so that the powder butterfly valve that is activated is mainly used as a shut-off valve, and can also be designed to have an adjustment or a segment. Valve and regulating function, the current use of powder butterfly valve in the low pressure large and medium diameter pipe is more and more.

Due to these characteristics of the powder butterfly valve, the powder butterfly valve has unique characteristics compared to other butterfly valves. From many aspects, we can see that various powder butterfly valves are used in different occasions when used. The powder butterfly valve looks round and round on the outside, and the surface is slightly yellow and slightly cute. Since the fluid resistance of the powder butterfly valve is small, the effective circulation area of the large and medium-sized powder butterfly valve is large when opening, the opening and closing is quick and labor-saving, and the disk plate can be rotated and rotated by 90 degrees to complete the opening and closing, due to the disc plate medium on both sides of the rotating shaft. The functions are nearly equal, and the generated torque directions are opposite, so that the opening and closing torque is small, and a good seal can be achieved at a low pressure, which has excellent sealing performance at low temperatures.

After using it for a period of time, the inside of the valve leaked, causing the stone powder to leak into the workbench frequently in piles. This is because the medium is very thin and a little sticky. Although the compounding trolley is equipped with a vibration motor, many materials are attached to the tank. On the wall and in the valve part, when the valve is closed, it is stuck around the sealing surface, so that the valve can not be completely closed, so that the leakage occurs after reloading the material. Over time, the sealing surface is worn very badly, and even the groove is present. .
