Maintenance and commissioning of pneumatic butterfly valve
1. The inspection and maintenance plan of the cylinder is to clean the cylinder surface and add oil to the cylinder shaft circlip at ordinary times, and open the cylinder end cover regularly every 6 months to check whether there are sundries and moisture in the cylinder and whether the lubricating grease is in good condition. If the grease is insufficient or dry, the cylinder shall be disassembled for comprehensive maintenance and cleaning before adding grease.
2. Valve body inspection Every six months, check whether the valve body appearance is good, whether the installation flange has leakage, if it is convenient to check whether the valve body seal is good, whether there is wear, whether the valve plate operates flexibly, and whether the valve has foreign matters stuck.

Do you know what to do after plastic coated pneumatic butterfly valve is split
Plastic coated pneumatic butterfly valves are more and more widely used in society, and play an indispensable role in our life, especially in professions such as steel, petroleum, chemical industry, and even in harsh environments with a lot of dust, flammable and explosive gases.
Therefore, in order to prevent problems in the application of plastic coated pneumatic butterfly valves, we have thought of some precautionary measures according to various elements in advance, and always improve them from time to time. Now let's take you to know what to do after the plastic coated pneumatic butterfly valve is united? Plastic coated pneumatic butterfly valve
1. Restructuring method:
Saw off Tuanjie plastic coated pneumatic butterfly valve; Find the ability, length and unity under pressure
Approximate substitute hose and saw off its pipe joint; Weld the sight point of the pneumatic butterfly valve connector of the uniting hose on the alternative hose; The welded hose can be used after cleaning.
2. Bone connection:
Wipe and clean the bonding part of plastic coated pneumatic butterfly valve and cut off the bonding part; Insert the self restrained steel "boning" into the blocked hose. When the situation is particularly urgent, the steel pipe with the same outer diameter as the hose bone diameter can also be used as the "boning"); Clamp the hose and the "bone connection" with a steel plate clamp (when the situation is extremely urgent, No. 8 iron wire can be used to replace the steel plate clamp); The connected plastic coated pneumatic butterfly valve can be used after cleaning.
3. Binding method:
Apply one of the common adhesives for construction machinery to the joint of plastic coated pneumatic butterfly valve; Wrap 2-3 layers of oil resistant rubber with width 2-3 times the length of the bonding part (each layer shall be coated with glue); Bind the wrapped oil resistant rubber with No. 12 iron wire; Let it coagulate.
