Fine Smart Electric Actuator
Installation
Indoor installation matters at the installation site It is a non-explosion-proof product. Do not install it in a room with explosive gases. Please reserve space for incoming wires and manual operation.
Precautions for outdoor installation Please install a protective cover and make sure the wiring cover is tightly closed after wiring for safety precautions Note: Direct sunlight will cause high temperatures inside the machine and accelerate the aging of components. Rainwater will accelerate the aging of seals, causing water seepage and damaging the machine.
Match With Electric Ball Valve
Introduction To Ball Valve
The opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-shaped ball valve has a strong shear force between the V-shaped ball core and the metal valve seat with hard alloy surfacing. It is especially suitable for materials containing fibers and tiny solid particles. etc. media. The multi-way ball valve can not only flexibly control the confluence, divergence, and flow direction switching of media on the pipeline, but can also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in pipelines. Ball valves are divided into pneumatic ball valves, electric ball valves and manual ball valves according to the driving mode.
Installation And Maintenance Of Electric Ball Valve
1. When the electric ball valve is closed, there is still pressurized fluid inside the valve body;
2. Before maintenance, release the pipeline pressure and keep the valve in the open position; disconnect the power or air source; disengage the actuator from the bracket;
3. It is necessary to confirm that the pressure in the upstream and downstream pipelines of the electric ball valve has been relieved before disassembly and disassembly can be carried out;
4. When disassembling and reassembling, care must be taken to prevent damage to the sealing surfaces of parts, especially non-metallic parts. Special tools should be used when removing the O-ring;
5. During assembly, the bolts on the flange must be tightened symmetrically, gradually and evenly;
6. The cleaning agent should be compatible with the rubber parts, plastic parts, metal parts and working media (such as gas) in the ball valve. When the working medium is gas, gasoline (GB484-89) can be used to clean metal parts. Clean non-metal parts with pure water or alcohol;
7. The decomposed individual parts can be cleaned by dipping. Metal parts that still have undecomposed non-metallic parts can be scrubbed with a clean, fine silk cloth soaked in cleaning agent (to prevent fibers from falling off and adhering to the parts). During cleaning, all grease, dirt, glue, dust, etc. adhering to the wall surface must be removed;
8. Non-metal parts should be taken out of the cleaning agent immediately after cleaning and should not be soaked for a long time;
9. After cleaning, it is necessary to wait for the cleaning agent on the wall to be washed to evaporate (it can be wiped with a silk cloth not soaked in cleaning agent) before assembly, but it must not be left aside for a long time, otherwise it will rust and be contaminated by dust;
10. New parts also need to be cleaned before assembly;
11. Use grease for lubrication. Grease should be compatible with ball valve metal materials, rubber parts, plastic parts and working media. When the working medium is gas, special 221 grease can be used. Apply a thin layer of grease on the surface of the seal installation groove, apply a thin layer of grease on the rubber seal, and apply a thin layer of grease on the sealing surface and friction surface of the valve stem;
12. During assembly, metal chips, fibers, grease (except those specified for use), dust and other impurities, foreign matter, etc. should not be allowed to contaminate, adhere to, or stay on the surface of the part or enter the inner cavity.
Electric Ball Valve Structure
There are many types of electric ball valves. They are generally divided into two categories according to their structural forms, namely O-type structure and V-type structure. The ball openings of the two are different and their applications are also different. The O-type is generally suitable for shut-off use and occasional adjustment. , while the V-type is more suitable for adjustment (larger adjustable ratio).
O-type ball valve structure: The O-type ball valve has a ball with a middle through hole installed inside the valve body. The ball has a through hole with a diameter equal to the diameter of the pipe. When fully open, it is a non-blocking valve with large flow capacity and no directionality of fluid entering the valve. The ball can rotate in the sealing seat, and there is an annular elastomer on both sides in the direction of the pipeline to achieve sealing. By rotating the ball 90°, the direction of the through hole can be changed, thereby realizing the opening and closing of the ball valve.
V-shaped ball valve structure: The ball core of the V-type ball valve has a V-shaped structure. The valve core is a 1/4 spherical shell with a V-shaped notch. As the ball rotates, the opening area changes, but the shape of the opening surface always remains triangular, and the flow characteristics are similar to others. Percent, adjustable ratio is large. It has the characteristics of large flow capacity, large adjustable range, shear force, and tight closing ability. It is especially suitable for working conditions where the fluid material is fibrous. Generally, V-shaped ball valves are single-seal ball valves. Not suitable for two-way use.
Operation And Use Of Electric Flange Ball Valve
1. Make sure the pipelines and valves have been flushed before operation.
2. The operation of the valve is completed by rotating the valve stem (manual or automatic control mode): when rotated 1/4 turn (90°) clockwise, the valve is closed. When rotated 1/4 turn (90°) in the opposite direction, the valve opens.
3. When the groove direction at the top of the handle or valve stem is parallel to the pipeline, the valve is open.
4. The torque of the valve stem will vary depending on the following factors: the length of time the valve opens and closes, the medium of the pipeline system, the pipeline pressure and the type of valve seat, etc.
