Ash Discharge Valve

The opening and closing part of the electric plug valve is a gate plate, and the direction of movement of the gate plate is perpendicular to the direction of the fluid. The electric plug valve can only be fully opened and fully closed and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form a wedge, and the wedge angle varies with the valve parameters.

Principle: There is a round opening of a diameter on the gate, and the opening and closing of the gate makes the round opening on the gate to completely separate from and match with the diameter.

Electric three-way valves are used for air conditioning, thermal ventilation, heat treatment in heat treatment plants, and industrial fluid control.

Air-conditioning, heating, ventilation, domestic hot water and other civil systems and chemical, petroleum and metallurgical and fluid automation.


Manual insert valve is also called spiral gate valve, it is to control the discharge of materials. Often supporting electric feeder, rotary ash unloading valve and other use, mainly to facilitate the electric feeder, star unloader maintenance can be controlled when the material is closed in the silo does not leak out, it is compact, simple operation, long service life, not prone to failure.

Ash Discharge Valve Working Principle

Star unloader, also known as electric ash unloading valve, ash discharge valve, pneumatic discharge valve, rotary discharge valve, etc. This product is mainly the main equipment for bag filter conveying, ash discharge and other equipment unloading, suitable for powder materials, granular materials, widely used for environmental protection, mining, metallurgy, chemical industry, food, chemical and other industrial sectors.

Unloader is divided into three categories: common type, pressure resistant type and high temperature resistant type. Unloaders can be driven at a uniform speed to discharge materials continuously according to the controlled rate, or driven at a variable speed to use the unloader as a feeder.

Product features.

(1) The unloader adopts the principle of planetary rotation, the input and output are on the same axis, and it has the uniqueness of being directly connected with the motor, so the structure is compact, beautiful and novel, small volume and light weight.

(2) The unloader runs reliably and smoothly, with low noise, low failure and long life, and the gear housing parts are made of ductile iron and bearing steel. Good performance and high wear resistance.

(3) The bearing, gear box, away from the valve body, to avoid the influence of high temperature dust, good sealing performance of the front and rear end cover, to prevent dust leakage, prolong the service life of the transmission parts, lubrication system.

(4) The unloader has strong overload capacity, impact resistance, small inertia torque, suitable for frequent start/stop and forward/reverse rotation.

(5) Users need special specifications, motor, sprocket drive and other unloaders, can be made. According to the user needs to configure special special motor, such as explosion-proof, frequency control, speed control, marine motor, etc., to meet the special requirements of users. In the material can also be according to user needs for special processing, such as high temperature resistance, corrosion resistance, stainless steel, flexible blade, explosion-proof impeller, etc.

Electric Ventilation Butterfly Valve is mainly used in the dusty cold wind or hot air gas pipelines of ventilation, environmental protection projects in metallurgy, chemical industry, building materials, power stations, glass and other industries, as a gas medium to regulate the flow or cutting device.

Pneumatic plug-in valve is a main control equipment for the flow or delivery of powder, crystal grain, granular materials and small pieces of material. It is widely used in metallurgy, mining, building materials, food, chemical and other industries to control flow changes or cut off quickly. Pneumatic flapper valve has the advantages of simple structure, flexible operation, light weight, no jamming, and is especially suitable for the transportation and flow regulation of all kinds of solid materials and about 50mm block and lump materials. The installation is not limited by the angle and is easy to operate. Can adjust the scale at any time. Structural features: Simple structure, flexible operation, light weight, no jamming, fast cutting, especially suitable for all kinds of non-viscosity solids, powders, and granules less than Φ10mm, transportation of crystal grain and flow regulation, installation is not limited by the angle , Easy to operate, can adjust the opening degree at any time. Mainly used for building materials, metallurgy, mining, electricity, chemicals, glass, light industry, food and other industries, the top, bottom and import and export. It is the reason that the control flow changes greatly, starts frequently, and cuts off rapidly.
