Installation and maintenance of electric ball valves and daily maintenance

The electric ball valve has the action of rotating 90 degrees, the body is a sphere, there is a circular through hole or channel through its axis.
the main features of the electric ball valve itself are compact, reliable sealing, simple structure, easy maintenance, sealing surface and spondy often in a closed state, not easy to be eroded by the media, easy to operate and repair.
ball valve in the pipeline is mainly used to do electric ball valve cut-off, distribution and change the flow direction of the medium, it only needs to rotate 90 degrees of operation and a small torque of torque to close tight.
the installation and maintenance of the electric ball valve 1, only to remove the pressure before and after the ball valve, the ball valve can be removed and decomposed operation.
be tightened symmetrically, gradually and evenly when the ball valve body is reassembled.
3, cleaning agent should be compatible with rubber parts, plastic parts, metal parts and working media (e.g. gas) in the ball valve.
can be used to clean metal parts with gasoline (GB484-89) when the working medium is gas.
non-metallic parts are washed with pure water or alcohol.
4, decomposed individual parts can be washed by way of immersion.
cleaning, remove all grease, dirt, glue, dust, etc. that adhere to the wall.
Electric ball valve daily maintenance 1, with a long service life and repair-free period, will rely on the following factors: normal working conditions, maintain a harmonious temperature/pressure ratio, as well as reasonable corrosion data 2, ball valve in the closed state, the valve body still exists under pressure fluid 3, before repair: lifting the pipeline pressure and leaving the valve in the open position; The downstream pipe has indeed removed the pressure, in order to remove the decomposition operation 5, decomposition and reassembly must be careful to prevent damage to the sealing surface of the part, especially non-metallic parts, when removing the O-ring should use special tools 6, the bolts on the french flan at assembly time must be symmetrical, gradually and uniformly tightened 7, the cleaning agent should be compatible with the rubber parts in the ball valve, plastic parts, metal parts and working media (e.g. gas).
can be used to clean metal parts with gasoline (GB484-89) when the working medium is gas.
Non-metallic parts with pure water or alcohol cleaning 8, non-metallic parts should be immediately removed from the cleaning agent after cleaning, not long-term immersion 9, cleaning need to wait for the wall cleaning agent volatile (can be used un-immersed cleaning agent silk cloth rub) for assembly, but not for a long time, otherwise it will rust, dust Contamination 10, new parts before assembly also need to clean 11, assembly should not allow metal debris, fibers, grease (except for the prescribed use) dust and other impurities, foreign objects and other pollution, adhesion or stay on the surface of the part or into the inner cavity, if there is a slight leakage at the filler, the valve rod nut must be locked again.
electric ball valve electric ball valve is suitable for switching, cutting off valve use, but recent developments have designed the ball valve to make it with throttle and control flow, such as V-type ball valve.
is suitable for general working media such as water, solvents, acids and natural gas, as well as for mediums with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, and is widely used in various industries.
ball valve body can be holistic or combined.
