Description:

Productoverview:
A41Y series Spring micro open closed high-pressure safety valve The equipment and piping for working temperature are less than 200 air, nitrogen and hydrogen mixed gas, water and other media. A41Y-160P/320P, A41Y- 160R/320R for working temperature are less than 200 have the equipment and piping of corrosive gas or liquid medium, as the overpressure protection device. According to the JB/T2769-92 standard flange.
Two, A41Y Spring micro open closed high-pressure safety valve The paper discusses the structure of:
1, spring micro open type safety valve has the advantages of simple structure, good sealing performance, accurate open pressure, discharge capacity, back seat pressure difference is small, easy to adjust.
2, the nozzle type seat: the seat for a cut of the nozzle seat that reaches the speed of sound at the outlet of the steam flowing through the valve, discharge coefficient, surfacing Stellite seating, erosion abrasion resistance, long service life.
3, thermal elastic disc: disc design for thermal elastic structure, using the medium pressure tiny deformation, improve the sealing ability, overcome the safety valve setting of the pressure is near before discharge phenomenon in the medium pressure. The valve sealing surface using advanced laser quenching technology, improve the hardness, wear resistance, impact resistance.
4, the adjusting nut: by adjusting the adjusting nut, adjust the amount of compression spring, the valve can conveniently and quickly get accurate setting pressure.
5, back pressure adjusting sleeve valve back pressure adjustment: auxiliary mechanism, through the back pressure adjustment adjustment, can get the right back to a pressure difference. When raised, the back pressure reducing valve. Cut, make the valve back pressure increased.
Three, A41Y Spring micro open closed high-pressure safety valve Installation instructions:
1, the valve must be installed vertically, and best installed directly in the container or pipe joints. The import of the inner diameter of the joint should not be less than the safety valves.
2, the safety valve must be installed the export of appropriate expansion joint, to prevent the discharge pipe thermal expansion safety valve to bring unnecessary heat stress. The discharge pipe diameter than the valve outlet should be of large diameter and length as short as possible, avoid turn. Discharge pipe and expansion joint weight should not be in the safety valve should be fixed on the building.Distance between the center lines of the discharge tube and the valve between the as short as possible. For each set of safety valve should be installed separately discharge tube.
Exit 3, muffler to have enough area, prevent the discharge capacity of the valve back pressure effect.
