when high-pressure liquid is introduced into the pressure reducing valve, the buffer block 205 is impacted firstly, the buffer block buffers the liquid through the first connecting rod 204 and the first spring 210, after the liquid fills the inside of the outer shell 2, the internal pressure is increased, the valve port 310 is pressed and opened, the internal high-pressure liquid flows out in a small amount, and the released liquid impacts the supporting rod 108 to enable the detecting spring 107 to bear force to display the pressure value on the pressure gauge through data.
The valve block 302 is driven by the second connecting rod 303 to open upwards, the second spring 304 is compressed by extrusion deformation, the non-newtonian fluid 308 in the cavity 307 is hardened when being impacted greatly due to the fact that the valve is opened, the buffer plate 306 is unchanged in position under the extrusion of the second spring 304, after the pressure is stable, the non-newtonian fluid 308 begins to soften slowly, the buffer plate 306 moves slowly in the non-newtonian fluid 308, the second spring 304 returns to the original state, the powerful spring 312 is extruded and deformed when the second connecting rod 303 moves, hydraulic oil is arranged in the hydraulic cavity 315, and when the clamping plate 313 moves, the inside of the hydraulic cavity 315 is extruded to send the hydraulic oil into the impact base 203 through the hydraulic cavity 315 to lubricate the impact base 203.
The replacement can be performed by opening the cover 211 when the strong spring 312 is continuously pressed to cause fatigue damage.
When the pressure in the pressure reducing valve is too large, the buffer block 205 is excessively pressed to press the diamond-shaped block 208 downwards so that the diamond-shaped block is not sealed with the outer shell 2, and liquid in the pressure reducing valve can be output through a pressure reducing component on the other side of the pressure reducing valve.
