Product Description
1. product introduction:
Manual flapper valve, also known as manual spiral gate valve, is easy to install by flange connection. The inlet and outlet are square and round. There are dozens of specifications according to the size of the caliber. It is installed on various powder-particle material pipelines with pressure to play the role of opening and closing. Its maximum operating pressure can reach 1MPa. Manual plug-in valve has the characteristics of good sealing without internal and external leakage, and the parts that are easy to wear are made of wear-resistant materials. At the same time, the structure of the valve takes full account of the characteristics of the powder material, so that the valve rarely appears to be stuck in the valve plate can not slide. Widely used in metallurgy, carbon, chemical, building materials and other industries.
Manual square flapper valve is also called manual knife gate valve. Knife gate valve is a valve in which the gate plate and the valve seat are always in close contact and sealed. Its principle is that the gate plate is provided with a round opening with a diameter. The opening and closing of the gate plate makes the round opening on the gate plate completely separate from the diameter and match the movement. Manual flapper valve is the main control equipment, widely used in metallurgy, mining, building materials, food. Manual flapper valve usually manual flapper valve is a kind of powder, grain material, granular material and small pieces of material flow or conveying amount of supporting the use of unloader, manual screw gate valve diameter and unloader feed port matching, there are two kinds of square and round.
The manual square flapper valve is installed on the pressure of various powder material pipelines to play the role of opening and closing. Its zui service pressure can reach 1MPa. Manual plug-in valve has the characteristics of good sealing without internal and external leakage, and the parts that are easy to wear are made of wear-resistant materials. At the same time, the structure of the valve fully considers the characteristics of the powder and granular materials, so that the valve rarely appears the phenomenon of being stuck in the valve plate and not sliding.

3. product installation method of use:
1. When the valve is installed on the pipeline, the valve stem can be upward or horizontal.
2, check whether the thread connection is loose, and adjust the tightening;
3, remove the valve channel at both ends of the cover, clean the inner cavity, remove grease;
4. After peeling off the protective oil paper of the valve stem, re-apply grease on the valve stem;
5. Flush and clean the pipeline to avoid damage to the sealing surface.
6. When the valve is opened and closed, the electric (pneumatic) actuator is opened and closed through the lifting of the valve stem. The force should be uniform during the opening and closing process. Before it is in place, it should be opened slowly and gradually in place or closed to seal.
4. manual square flashboard valve features:
Light weight: about 1/3 of the weight of the ordinary gate.
Corrosion resistance: acid and alkali resistance and most of the corrosive chemicals and sewage seawater.
Good sealing: rubber soft seal, good sealing effect
Small torque: due to the light weight of the gate and the small frictional resistance between the gate and the rail plate, the operating torque is small.
Long life: between the gate and the guide rail is equipped with anti-lock structure so that the sealing surface wear is very small.
