Alumina Ceramics:

Alumina ceramic controlled check valves are often used in pressure holding, pressure relief, and locking circuits. Due to the pressure in the system, the oil is compressed, the pipe is expanded, the components are elastically deformed, etc., and the energy is stored. When the pressure is released, the amount of kidney is suddenly released, and when the reversing valve is from the neutral position to the left position. Because the pressure in the upper chamber of the hydraulic cylinder is large, the pressure in the lower chamber has risen at this time, and the unloading valve and the main valve are opened at almost the same time, so that the pressure oil in the upper chamber is suddenly released to the returning oil passage through the hydraulic control check valve. Because of these two reasons, the pressure-reducing small tea pressing machine is too fast, causing impact vibration and noise. For this reason, we have improved this type of hydraulic circuit.
   Due to the high pressure and large flow hydraulic control check valve, the pressure relief is too fast, and the impact is increased. Therefore, a throttle valve is added to the circuit, so that the pilot valve unloading valve is opened first, then opened again. The main valve, because the throttle valve has a sufficient flow control range, can ensure a stable small flow, easy adjustment, small leakage, temperature and pressure have little effect, so by adjusting the throttle valve, control the oil in the upper chamber of the hydraulic cylinder The liquid pressure relief time is also extended accordingly, the pressure-reducing capacity is also enhanced, and the impact and noise of the hydraulic oil on each component are returned.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
