Pneumatic Square Slide Gate Valve
Product Description
Pneumatic slide gate valve is a main control equipment for the flow or conveying volume of powder, crystalline, granular, and small materials. It is widely used in industries such as metallurgy, mining, building materials, grain, chemical, etc. to control flow changes or quickly cut off.
Product Features
Structural Features
Simple structure, flexible operation, light weight, no jamming, especially suitable for the transportation and flow adjustment of various solid materials and about 50mm block and cluster materials. Installation is not limited by angle, operation is convenient, and scale can be adjusted at any time. Structural characteristics: simple structure, flexible operation, light weight, no jamming, fast cutting, especially suitable for various viscosity free solids, powders, and particles smaller than 10mm. The conveying and flow regulation of crystalline particles are not limited by angle, easy to operate, and the opening can be adjusted at any time. Mainly used for the top, bottom, and import and export of warehouses in industries such as building materials, metallurgy, mining, power, chemical, glass, light industry, and grain. It is an ideal device for controlling large flow changes, frequent startup, and quick shutdown.
Specification
Specification
1. The shell and sealing test media for the plug-in valve are water (including preservatives), kerosene, or other suitable liquids with a viscosity not greater than water.
2. The sealing pair is a non-metallic sealed plug-in valve, and the sealing shell test and requirements are in accordance with GB/T13927-92 Class D.
3. The sealing pair is a metal sealed plug-in valve. For those with sealing performance requirements, the leakage rate of the sealing test is calculated at 1 x DNmm/s. For those without sealing performance requirements, this test is not conducted.
4. The plug-in valve driven by electric, hydraulic, and pneumatic devices, after adjusting the closing position, is closed three times and subjected to shell and sealing tests according to the requirements of 1 and 3.
5. The cleanliness requirements of the plug-in valve shall comply with the provisions of JB/T7748.
6. Static pressure life test.
7. The number of static pressure life tests for the plug-in valve shall be in accordance with the regulations, while other technologies shall comply with the provisions of JB/Z 234
Working Principle
Working Principle
Using compressed air as power, the direction of the air path is changed by reversing the solenoid valve, pushing the cylinder piston and driving the gate plate to move back and forth in the horizontal direction, achieving the purpose of opening and closing the gate.
