Installation and usage notes for air valve
Air valves are industrial valves that open and pressurize the pipeline to obtain and maintain a required pressure during the production operation. The installation and use of air valves are the basis for ensuring that the equipment has a reasonable pressure and preventing accidents. The following is a short introduction to the installation and use of air valves.
1. The overall installation of the air valve should be reasonable and reasonable, and the parts and accessories should be complete and in good condition.
2. The air valve should be accurately and reliably installed on the pipeline and plumbing system. The pipeline installation should be balanced. The air valve must not be tilted, and the connection should be firm and reliable.
3. When installing the air valve, it must be ensured that the direction of the valve is consistent with the direction of the material flow in the pipeline.
4. Each form of the air valve has a specific operating pressure. When installing and using, this pressure must be strictly controlled so as not to exceed the operating pressure of the air valve.
5. The air valve should be regularly checked and the reliability of the fixed connection and sealing should be confirmed to ensure the normal use of air valves.
6. Before the valve is opened, the vent screw of the connection should be screwed and the valve should be opened slowly, not too much too quickly, to prevent water hammers, water bursts and other phenomena.
7. After the valve is closed, the vent bolt should be tightened.
8. If the air valve is long-term unused, the valve should be regularly opened and closed to prevent the valve from being stuck or stuck.
9. The air valve should be regularly removed from the pipeline for cleaning and maintenance.
10. When using the air valve, it is strictly forbidden to open or close the entire valve in extreme weather such as wind, rain, snow and ice.
In general, the installation and use of air valves must be done strictly according to the corresponding technical requirements. In order to ensure the safety and reliability of its application, it is necessary to strengthen the inspection, maintenance and maintenance of air valves, periodically check and adjust the medium pressure and actively take preventive measures in order to avoid dangerous situations.
