The air compressor safety valve has the spring type and the rod type two big categories.
The spring-type safety valve works mainly by the force of the spring. In the spring-type safety Valve, there are closed and non-closed ones. Generally, the inflammable, explosive or toxic medium should be closed, and the steam or inert gas, etc. , can be non-closed, also available in spring-loaded relief valves are those with and without wrenches.
Lever-type safety valve mainly relies on the action of the lever hammer and work, but because of the large size of the lever-type safety valve often limits the scope of selection. When the temperature is high, choose the safety valve with radiator.
Air compressor safety valve is the main parameter of displacement, this displacement depends on the size of the valve seat and the opening height of the disc, by the opening height is different, and divided into micro-open and full-open two. Micro-opening means that the opening height of the disc is 1 / 40 ~ L / 20 of the seat throat diameter. Full opening means that the opening height of the disc is 1 / 4 of the seat throat diameter.
As the name suggests, safety valve is to ensure the critical safety of pressure pipelines and pressure vessels. In order to ensure the normal work of safety valve and extend the service life of safety valve, in the use of the safety valve should be regularly check whether the operation of leakage, blockage and spring rust and other abnormal phenomena and pay attention to observe whether the adjustment nut and the adjustment ring locking screw loose, take appropriate maintenance actions in time if problems are found.
Safety valve should also be removed regularly for full cleaning, inspection and re-grinding, setting before re-use. Safety valve installed in outdoor to take appropriate protective measures to prevent rain, fog, dust, rust and other debris into the safety valve and discharge pipeline when the environment is below zero degrees celsius, the necessary anti-freezing measures should also be taken to ensure the reliability of safety valve operation. This type of valve in the pipeline should generally be in accordance with the correct installation of operating conditions.
