Pressure Vacuum Relief valve
 

 Single-call valves are generally installed horizontally in pipelines. The single-call valve makes full use of the pressure-bearing capacity of the oil tank itself to reduce the discharge of oil vapor. Its principle is to control the positive expiratory pressure and negative inspiratory pressure of the oil tank by using the weight of the valve disc. The single-call valve makes full use of the pressure-bearing capacity of the oil tank itself to reduce the discharge of oil vapor, so that the pressure in the tank does not continue to decrease.

superiority

 

   Compact structure, small leakage, good sealing performance, easy cleaning and other advantages, and with the continuous refinement of the general category of breathing valves, it will also be applied to different industries according to its own design, providing security for more industrial production.

function

It makes full use of the pressure-bearing capacity of the oil tank itself to reduce the discharge of oil vapor, so that the pressure in the tank does not continue to decrease.

care and maintenance

Necessary maintenance can not only ensure the safe operation of industrial production, but also prolong the service life of breathing valve; Secondly, understand the steps of maintenance: usually once a month, and in winter we will do it twice a month on average; Maintenance method: after the valve cover is opened, take out the vacuum valve disc and pressure valve, and then check whether the sealing part of the valve disc and the guide rod are stained with oil stains and stolen goods. If oil stains appear, they should be cleaned up, and then reassembled after everything is cleaned up, and check whether they are reliable; Of course, if the valve disc is scratched or cracked during use, it should be replaced immediately or contacted with the supplier.
