Electric flange ball valve installation instructions

The working principle of the electric flange ball valve is to open and close the valve through the power drive and rotate the valve stem. It has the characteristics of light switch, small size, reliable sealing, simple structure and convenient maintenance. Due to the sealing surface and spherical surface of the electric flange ball valve Often in the closed state, it is not easy to be eroded by the medium, and it is widely used in various industries. As for the correct installation of the electric ball valve is related to the operating conditions of the working conditions and the safety during use, the user should understand the instructions for use.

1. Preparation before installation
1. The front and back pipelines of the electric flange ball valve have been prepared. The front and rear pipes should be coaxial, and the sealing surfaces of the two flanges should be parallel. The pipeline should be able to bear the weight of the ball valve, otherwise the pipeline must be equipped with proper support.
2. Purge the pipelines before and after the valve to remove the oil, welding slag and all other impurities in the pipe belt.
3. Check the mark of the ball valve to find out that the ball valve is intact. Fully open and close the valve several times to verify that it is working properly.
2. Installation method and steps of electric flange ball valve
1. Remove the protective covers on both sides of the flange, and rinse and clean with the valve fully opened.
2. Check the valve hole, and then clean the valve hole. Flush and remove all accumulated impurities in the pipeline (these substances may damage the valve seat and ball).
3. During installation, please do not use the valve stem or handle (handwheel) part of the valve as a fulcrum for lifting objects to avoid collapse and other accidents.

4. Install the valve on the pipeline. This type of valve can be placed in any position and direction of the pipeline. The two ends are each fixed on a flange piece, and then flange gaskets are added between the two flange plates to fix it.
5. The pipeline near the installation point should not be drooping or bear external forces. Pipe supports or supports can be used to remove the deviation of the pipeline.
6. Finally, use bolts to align the two flange pieces with the flange holes and tighten them to make them tightly connected. (Some pipes or pipe fittings have their own flanges.)
3. Operation and use of electric flange ball valve
1. Make sure that 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 it rotates 1/4 turn (90°) clockwise, the valve is closed. When the reverse rotation is 1/4 turn (90°), the valve opens.
3. When the direction of the handle or the groove on the top of the valve stem is parallel to the pipeline, the valve is open.
4. The torsion of the valve stem will vary according to the following factors: the length of time the valve is opened and closed, the medium of the pipeline system, the pipeline pressure and the type of valve seat, etc.

Installation instructions for ball valves

Installation instructions for ball valves:

1. Indoor devices or outdoor applications with protective methods;

2. Outdoor installations are corroded by wind, sand, rain, dew, and sunlight;
3. Have flammable, explosive gas or dust environment;
4. Humid tropical and dry tropical environment;
5. The temperature of the pipeline medium is as high as 450℃;
6. The ambient temperature is lower than -20℃;
7. Easy to be flooded or immersed in water;
8. Possess a radioactive material (nuclear power plant and radioactive material test device) environment;
9.The environment on the ship or dock (with salt spray, mold, humidity);
10.Occasions with severe vibration; occasions prone to fire;

For the electric ball valve in the above environment, the electric device structure, material and protection method are different. Therefore, the corresponding valve electric device should be selected according to the above-mentioned obligation environment. According to engineering control requirements, for electric ball valves, their control functions are completed by electric devices. The purpose of applying electric ball valves is to complete non-manual electrical control or computer control of valve opening, closing and adjustment linkage. The application of electric devices is not just for diligence and labor saving. Since the functions and quality of products from different manufacturers are quite different, the selection of electric devices and the selection of valves are equally important to the project. As the requirements of industrial automation level are constantly improving, on the one hand, the application of electric valves is increasing, and on the other hand, the control requirements for electric valves are getting higher and higher and more complicated. Therefore, the design of electric valves in electrical control is always updated. With the continuous improvement of use requirements and the popularization and application of computers, new and diverse electrical control methods will always appear. Regarding the overall control of the electric valve, attention should be paid to the selection of the control method of the electric valve. For example, depending on the needs of the project, whether to use a centralized control method or a single control method, whether to link with other equipment, sequence control or application computer sequence control, etc., the control principles are different. The sample of valve electric device manufacturers only gives standard electric control principles, so the application department should make technical clarifications with the electric device consumer to understand the technical requirements.
