Features of manual board valve
A flapper valve is a device used to block the transport of fly ash and powdered dry matter in a system. It can be installed under fossil-fuel power station, grey drums such as economizers, air preheaters, dry cleaners, flues, etc. , can also be used with armature. The maximum operating temperature is 200 °C. The device has the advantages of light weight, small volume, no fly ash, electric, pneumatic and manual operation. The advantages of manual valve and installation of dust removal valve are introduced.
1. Manual flapper valve has the following advantages:
1. The fluid resistance is small, and the resistance coefficient is equal to the pipe section.
2, the structure is simple, the volume is small, the weight is light.
3, strong and reliable, at present the ball valve sealing surface material widely used plastic and sealing, vacuum system has been widely used.
4, easy to operate, switch cabinet fast, from the front hall to the front hall only 90 rounds, easy to remote control.
5, maintenance is convenient, the ball valve structure is simple, the seal is generally in the active state, disassembly is more convenient.
6, completely open or completely closed, the ball and the sealing surface of the valve and media isolation, media through will not cause the valve sealing, sealing surface erosion.
7, wide range of application, from small to a few millimeters, large to a few meters, high vacuum and high pressure can be applied.
Manual knife-type smell gate valve, scientific name plate valve, a gate and seat always close contact with the sealing valve, scientific name insert plate valve. Gate valves are commonly used in non-particle liquid pipelines, causing damage to the sealing surface, or in steam pipelines sealed better. Its advantages are small fluid resistance, sealing surface by medium friction and erosion less, medium flow is not limited, does not hinder the flow, does not reduce the pressure, simple and easy. But the size of the larger shape, the need for a certain amount of space to open, and switch a long time. Between the sealing surface, easy to cause erosion and abrasions, so maintenance is more difficult. The gate valve is a kind of gate valve, which is usually used in the pipes of big granular liquid or solid or powder materials, better than environmental processing pipeline. But the plug, the valve has a precision structure, good workmanship, rigorous structure and other characteristics. K electric plug valve is a gate always close contact with the seat and sealed the valve. The opening and closing part is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, and can only be fully opened and closed, can not be adjusted and throttled. The gate has two sealing surfaces, the common mold gate valve has two, the sealing surface wedge angle changes with the valve parameters. The plug valve is installed on the outlet of all kinds of powder hopper or on the pipe to open and close, can also be adjusted to control the size of the opening, material flow, drive device can be used electric, pneumatic and manual devices. Suitable for metallurgical, chemical, grain industries, is an ideal material separation equipment.
