Pneumatic slurry valve

Pneumatic slurry valve

Pneumatic slurry valve This product continuously digests and absorbs the advanced features of similar product structures and manufacturing processes at home and abroad during production and application. Continuously improve the scientific and technological content of the products, starting from some technical details, and improve the comprehensive performance of the valve.

product description

The product can be automatically controlled to open and close the two positions by using accessories such as solenoid valves. Users can choose according to actual needs. Z673H series pneumatic slurry valve is complete. The main body is cast iron, cast copper, stainless steel, etc. The path is from DN50 to DN10000. Products are widely used in chemical, coal, sugar, sewage, paper and other fields, is an ideal sealing valve. Particularly suitable for the paper industry to adjust and throttle on the pipeline.

The valve is mainly composed of left and right valve body, U-shaped sealing ring, gate plate, steel nut, valve stem, bracket, hand wheel, etc. The valve opening and closing is completed by rotating the hand wheel, and when the valve rotates, the valve is closed. The opposite is to open the valve.

Product structure and characteristics

1. It adopts the clip-on structure, which is small in size and light in weight.

2. A fully open channel prevents media from depositing inside the valve.

3. The newly developed U-shaped sealing ring can ensure the good sealing of the valve.

4. The outer seal of the ram is realized by a sealing strip embedded in the valve body and can be adjusted by means of screws and pressure plates.

5. The flow resistance is small.

6, easy to install and maintain.

Gas and electricity control function description

1. The double-operated three-position five-way solenoid valve is used to control the pneumatic slurry valve cylinder. The three-position switch can be used to control the gate valve to stay at the upper limit, lower limit and any position.

2. When the valve stays at the upper limit position and the lower limit position, the limit switch of the upper limit position and the lower limit position issues a set of independent signal contacts that are normally open or normally closed. Can be used as a status indicator.

3. When the valve stays at the lower limit position of the upper limit position, the limit switch of the upper limit position and the lower limit position automatically cut off the power supply of the corresponding control coil of the solenoid valve. When the valve stays in the upper limit position and the lower limit position for a long time, the electric control coil of the electromagnetic valve is not energized, which can avoid the heating of the electromagnetic coil and improve the service life of the electromagnetic valve, thereby greatly improving the reliability.

4. When the valve stays in the upper limit position and the lower limit position for a long time; the gas source is cut off without gas consumption, but the air pressure of the cylinder of the lock valve is still kept in the cylinder, which can ensure reliable stop position.

5. During the cylinder switch process, when the control power is cut off, the cylinder inlet and outlet gas are also cut off at the same time. The air pressure of the cylinder of the lock valve is still kept in the cylinder. If the cylinder piston, solenoid valve and joint are leak-free, the gate valve can be in any position for a long time. Stay.
