The pressure reducing valve is an important component in the hydraulic system. Its main function is to keep the outlet pressure of the system at a level lower than the inlet pressure, to keep the outlet pressure of the system stable, and the system outlet pressure is not affected by the inlet pressure and flow fluctuation. However, once the pressure reducing valve leaks, it not only affects the normal production, but also causes the loss of hydraulic oil and pollutes the environment. In the marine hydraulic system, the pressure reducing valve is the main control component, and the importance of sealing is not to be underestimated. of.
1. Analysis of the static seal failure problem of the pressure reducing valve After research and analysis by related experts, it is found that the seal between the connecting sleeve of the pressure reducing valve and the valve body mainly depends on the O-ring between the connecting sleeve and the inner wall of the valve body. The circumferential seal, once the seal is effective, its external leakage is unavoidable.
2. Measures to solve the problem of pressure reducing valve sealing (1) Improve the surface quality of the pressure reducing valve.
(2) Ensure that the pressure reducing valve seals the amount of compression of the O-ring.
(3) Increase the pressure reducing valve end face seal (4) to reduce the friction between the O-ring of the pressure reducing valve and the sealing surface.
