Quick unloading valve works

Quick unloading valve works: it is connected to the upper part of a cup-mounted slide valve, the lower chamber of the slide valve and the lower part of the oil motive piston high pressure oil pipeline, and by the role of high pressure oil in the bottom of the cup valve slide A small hole in the middle, so that a small amount of pressure oil flow to the upper part of the spool of the oil chamber, the oil chamber has two, all the way through the check valve and the emergency cut off the oil connected to the normal operation due to cut off the oil on the Explorer equal to High pressure oil pressure it withstand check valve and make it closed, the upper part of the spool valve can not discharge the pressure oil from the road, the other oil through the needle valve control of the shrinkage hole, the control passed to the oil motor piston Cavity of the oil channel, regulating the opening of the needle valve can adjust the hydraulic pressure on the spool for debugging purposes. In normal operation, the upper part of the slide valve with the force of the spring plus the spring force is greater than the force of the lower part of the slide valve to make the cup valve slide on the base, and the oil return port is closed. When the steam turbine is faulty Solenoid valve action, cut off the oil pipe loss of pressure, the role of the cup-shaped slide valve on the top of the open check valve and drain, so that the valve pressure drops sharply the lower part of the high-pressure oil to promote sliding valve sliding, sliding The upper drain port of the valve sleeve is opened, so that the high pressure oil in the oil motor loses its pressure and rapidly drops under the action of the spring force. The main steam valve is closed and the unit is shut down.

Sensor Tri-proof Light

There are two types of sensors for Tri-proof Light; one is infrared induction, and the other is microwave induction.

Both types of sensors can control the following values through the remote control shown in the picture below:

1. Can set the light value. If the value of the ambient light meets the light value you set, it will not turn on even if there is a moving signal. When the ambient light does not meet the set value, the light will turn on.

2. The waiting time can be set. That is, how long the light stays low after the person leaves the sensing area.

3. Set the delay time, that is, how long the light stays in the full-on state after the person leaves the sensing area.

4. Set the preset brightness: you can set the full brightness and low brightness.

5. Set the detection range.

6. Remote control distance: You can set the distance range of the remote control sensor.

The function:

1.Switch function (stand-by period is set to "0s")

2.Two-stage dimming function (stand-by period is set to "+∞")

3.Three-stage dimming function (stand-by period is set to "0s/30s/10min/ +∞")

In addition, the LED Tri-proof Light can be waterproof, dustproof and anti-corrosion. Therefore, the Sensor Tri-Proof Light is especially suitable for parking lots.
