Hydraulic butterfly valve installation and maintenance guide
The hydraulic butterfly valve is a kind of control valve that controls the opening of the valve through hydraulic action, which is widely used in chemical industry, electric power, metallurgy, agriculture and other fields. In order to ensure the normal operation of the hydraulic butterfly valve and extend the service life of the valve, the installation and maintenance guide of the hydraulic butterfly valve is given below.
First, the installation of hydraulic butterfly valve
1. Determine the installation position
The hydraulic butterfly valve should be installed on a straight pipeline and perpendicular to the horizontal plane to ensure the stability of the hydraulic butterfly valve and the flexible opening and closing of the valve. In addition, during installation, please avoid installing the hydraulic butterfly valve at the turn of the pipeline and the direct contact of other pipeline components to avoid pressure fluctuations and flow rate changes.
2. Install the support
The mounting bracket should be firmly secured, the size matches the size of the valve, and should be installed at both ends of the pipeline.
3. Connect pipes
When connecting the liquid-controlled butterfly valve to the pipeline, follow the connection mode of the valve and pipeline. The connection method of the valve mainly includes flange connection, thread connection, clamp connection, etc. Special tools should be used when connecting, so that the tight connection shall not appear air leakage and water leakage problems.
4. Select pipe size
When installing the hydraulic butterfly valve, the appropriate pipe size should be selected to ensure the smooth flow of liquid and prevent the liquid flow speed from being too fast, affecting the control effect of the system.
Two, maintenance of hydraulic butterfly valve
1. Check the working condition of the valve regularly
Check the working condition of the hydraulic butterfly valve regularly, especially the opening and closing of the two aspects. If the valve is found to open or close too slowly or too fast, or the pressure is unstable, leakage and other problems, please promptly repair or replace the parts.
2. Clean parts regularly
The parts of the hydraulic butterfly valve are easy to accumulate sediment, dirt and other impurities in use, and regular cleaning can ensure its normal work. During the cleaning process, a safe and reliable cleaning agent with a cleaning effect should be used to ensure that the valve is not damaged.
3. Maintain the hydraulic butterfly valve regularly
Regular maintenance of the hydraulic butterfly valve can extend its service life. Maintenance should pay attention to the maintenance of various parts of the hydraulic system, and timely replacement of wearing parts.
4. Do a good job of anti-corrosion work of hydraulic control butterfly valve
The hydraulic butterfly valve is susceptible to corrosion in special environments, so it should be done according to the different medium properties and valve materials, such as spraying anti-corrosion paint on the valve surface.
In summary, the correct installation and regular maintenance of the hydraulic butterfly valve plays an important role in its normal use and extending its service life. In actual operation, users should be combined with pressure, temperature, media and other actual conditions, according to the actual situation selection, design, installation, maintenance and maintenance of valves.
