Wholesale Knife Slide Gate Valve

Slide gate valves help control gravity batch unloading when handling dry free flowing materials.powder, pellets, and granules,aggregates, clinker, coal, frac sand, fly ash, gravel, sand and whole grains.


We supply 3 gate valves:
1. Manual slide gate valve

2. Electric slide gate valve

3. Pneumatic slide gate valve
Electric plug-in valve: Electric plug-in valve is widely used in pipelines for the flow control of dust materials in metallurgy, mining, building materials and other industries, and is an ideal device for controlling the flow of dust materials. Structural features of electric one-way flat gate valve: Electric one-way flat gate valve adopts steel plate welding structure, self-resetting mechanism of counterweight rod, compact structure and stable operation. Electric plug-in valve, electric two-way flat gate valve The gate is mainly composed of a frame, a gate and a manual electric drive mechanism. The motor drives the gate to reciprocate in the horizontal direction through the rotation of the speed reducer through the sprocket to achieve the purpose of opening and closing the valve. The gate valve is simple in structure, light in weight, flexible in operation, and easy to assemble and disassemble. It is made of carbon steel, which has high strength, good performance and long service life. The screw and nut use a soft shield structure, which is not affected by external dust.
Electric plug-in valve is also called electric screw gate valve. Electric plug-in gate is usually used in combination with the unloader. The diameter of the electric screw gate valve is matched with the feeding port of the unloader, and there are two types: square and round. The advantage of this valve is that there is no groove in the valve body diameter, the medium will not be blocked, and it has the characteristics of full-bore flow, which is suitable for use in pipelines with powder and granular media. The sealing structure of the plug-in valve can be divided into soft sealing structure and hard sealing structure. The electric plug-in valve has the characteristics of good manufacturability and compact structure. The sealing valve seat is designed with a movable structure, which has the functions of anti-wear and automatic compensation, so it has a long service life. During the closing and opening process of the plug-in valve, the valve seat and the gate are always in close contact with each other, which makes the opening and closing force of the valve stable and has the characteristics of cutting off the medium.
The electric plug-in valve is the main equipment for the flow control of powder, crystal grain and small granular material. Electric slide valve is widely used in metallurgy, mining, building materials, food, chemical and other industries. The gate is equipped with electric, pneumatic and electro-hydraulic push rods as the driving device, which is an ideal device for controlling the flow rate and cutting off quickly. The plug-in valve has the advantages of compact structure, small leakage, easy operation, flexible action and labor saving, etc. It can work normally in the environment of high temperature, high dust and strong magnetism.
      Matters needing attention in the use of electric plug-in valve and its characteristics: the opening and closing part of the plug-in valve is the gate, and the direction of movement of the gate is perpendicular to the direction of the fluid. The plug-in valve can only be fully opened and fully closed, and cannot be adjusted and closed. Throttling. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50. The gate of the wedge gate valve can be made into a The whole is called a rigid gate; it can also be made into a gate that can produce a small amount of deformation. With its craftsmanship, it can make up for the deviation of the sealing surface angle during processing. This gate is called an elastic gate when the plug-in valve is closed. The sealing surface can be sealed only by the medium pressure, that is, relying on the medium pressure to press the sealing surface of the gate to the valve seat on the other side to seal the sealing surface, which is self-sealing. Most plug-in valves are forced to seal. That is, when the valve is closed, it is necessary to rely on external force to force the gate to the valve seat to ensure the tightness of the sealing surface.
Electric plug-in valve is the main equipment for the flow conveying control of powder, grain material and small granular material. Electric plug-in valve is widely used in metallurgy, mining, building materials, food, chemical industry and other industries. The gate is equipped with electric, pneumatic, electric As a driving device, the hydraulic push rod is an ideal device for controlling the flow rate and cutting off quickly. The plug-in valve has a compact structure, small leakage, easy operation, flexible action and labor saving. It can be used in high temperature, high dust, strong magnetic It can work normally in the environment. The nominal pressure of the electric plug-in valve: 0.05Mpa Applicable temperature: ≤600 ℃
