Respiratory valve for tanks of the filling station: function, construction, usage rules
safety, Security, efficiency of filling stations is directly dependent on the applied equipment, the accuracy of the placement and interconnect of all components. Every, even a minor component performs its role. Be sure the tanks equipped with respiratory valves. Their supply at a reasonable cost, the company offers PNSK.
Functions mechanical breathing valve
the Device comes with the tanks used for the storage and dispensing of diesel fuel, gasoline, and other petroleum products. On it rests several important functions. Among these are:
- regulation of the pressure inside the tank at the time of filling or pumping out content;
- system protection from the damaging effects of temperature fluctuations;
- prevent the entry of sparks or fire in the compartment with the fuel content.
Any kind of oil is exposed to natural evaporation. This has two negative consequences. A pair of oil into the atmosphere, polluting the environment. The owner of the station or the store loses money. Both problems effectively solves breathing valve of the tank, increases the tightness of the system.
Design and features
Breathing valve presented in the form of a metal body, inside which is located the working mechanism of the fire arrester. The shell is made from alloy steel, brass or aluminum. The tank he is joined by special threads. On the body is the cover. The main part of the valve consists of cage, rod, plates, and springs. Razor sparks and fire represented by a small magazine filled aluminum goreu.
the careful design of the mechanical valve allows it to be used in different conditions. The device is able to withstand fluctuations in temperature ranging from -50 to 50 degrees. High humidity (95%) does not violate its integrity and function. But before installing the valve, care must be taken ensuring molniezaschita.
a Mechanism for preserving the original indicators is in need of constant maintenance. It should be cleaned from solid clusters, to test for performance. It becomes impractical and unsafe use of defective valves. The frequency of their inspection depends on the external temperature conditions.
