Eventually by gross blow hole, speed control valve mounting hole and speed control valve and external atmosphere, holding piston lower surface is atmosphere
Pressure.
When gas spring is replied, piston rod is not under by external force, and piston, which pushes back, drives piston rod to move downward, at this time
Inner casing upper cavity pressure is greater than atmospheric pressure, i.e. pressure of the atmospheric pressure of piston upper surface greater than lower surface, piston upper and lower surface
The pressure difference of generation promotes that piston moves downward, and gas spring just has from recovery characteristic, and the reply speed of gas spring depends on here
In the speed of speed control valve inner air flow, air passage rates are fast, and gas spring is replied fastly, and air passage rates are slow, gas bullet
Spring is replied slow.
When needing real-time monitoring and adjusting inside of air spring air pressure, controller gets gas by pressure sensor
Gas pressure value in spring cylinder, controls the inflation of high-pressure inflating pump and dies, and controls the ventilation of 3 position-5 way solenoid valve and puts
Gas reaches the adjustment of inner pressure of air cylinder, and digital keys input our preparatory setting values, and the left side shows setting value on display screen,
The right shows real-time pressure value in the cylinder obtained from pressure sensor, and chip stores lower sensor data, and will press in real time
Force value is compared with setting value, then issues dependent instruction.
When real-time pressure value is less than setting value, chip, which issues instruction, allows high-pressure inflating pump to inflate, and opens simultaneously three five
The breather valve of three-way electromagnetic valve, air-flow reach air filter from high-pressure inflating pump transtracheal, then followed by five threeway electromagnetism
Valve, T-type pipe, quick-release connector and quick-release connector mounting hole reach outer shell, complete inflation, wherein mutual connection uses tracheae
Connection.
When real-time pressure value is equal with setting value, allows high-pressure inflating pump to stop inflating and close 3 position-5 way solenoid valve
Breather valve
When real-time pressure value is greater than the set value, chip issues the vent valve of instruction unpack 3 position-5 way solenoid valve, gas spring cylinder
Interior gas successively passes through, quick-release connector mounting hole, quick-release connector and T-type pipe, finally reaches 3 position-5 way solenoid valve, gas from
Gas outlet releases, and completes to deflate.
The inside that controller passes through controller to the control of high-pressure inflating pump and 3 position-5 way solenoid valve and pressure sensor
Circuit and external connection circuit are realized.
