Rexroth ASME Hydraulic Relief Valve Pressure Relief Valve DBDS10K1X315 IN010

Relief valve description

The pressure reducing valve, also known as the safety valve, is a valve that adjusts the inlet pressure to the pre-set outlet pressure through its own mechanical components, and relies on the energy of the medium itself to automatically maintain the outlet pressure.

Structure of pressure reducing valve

Pressure reducing valve according to the structure can be divided into film type, piston type, bellows type, etc., according to the working mode can be divided into positive action type, reaction type, unloading type and auxiliary valve type.

Measures to reduce or eliminate noise and vibration of pilot operated relief valves

All kinds of damping holes are provided on the damping sleeve to increase the damping and eliminate the vibration. In addition, due to the addition of parts in the resonator, the volume of the resonator is reduced, and the stiffness of the oil is increased at negative pressure. According to the principle that the components with large stiffness are not easy to resonance, the possibility of resonance can be reduced.

The anti-vibration pad is generally cooperated with the resonant cavity and can move freely. There is a throttling groove on both the front and back of the vibration cushion, which can produce damping effect when the oil flows to change the original flow situation. Due to the addition of the anti-vibration pad, a vibration element is added, which disturbs the original resonance frequency. The damping pad is added to the resonator, which also reduces the volume and increases the stiffness of the oil under pressure to reduce the possibility of resonance

A small air storage hole and a throttling edge are arranged on the damping screw plug. Because there is air in the small air storage hole, the air is compressed under pressure, and the compressed air has a suction function, which is equivalent to a miniature vibration absorber. When the air in the hole is compressed, the oil is filled in, and when it is expanded, the oil is hydraulically discharged, which adds an additional flow to change the original flow. Therefore, it can also reduce or eliminate noise and vibration.
