The principle of the blade lock is to use a tooth with a different angle of the bevel on the key to rotate and align the blade with different angle changes in the lock core, thereby realizing a lock in which the lock cylinder is rotated and opened.
Please pay attention to the direction of insertion of the key when using it: the key handle must be vertical, and the raised dot on the key handle (the key is correctly inserted into the direction mark) above can be inserted into the keyhole. After confirming that the key has been fully inserted, turn the key clockwise to unlock it. Never open the key when the key is not inserted, forcibly unlocking the key, causing the key to die in the lock cylinder and unplugging or twisting the key. The key cannot be pulled out during the rotation. Only when the key is turned counterclockwise, the key can be pulled out.
Since the lock cylinder adopts the structure of the springless blade, the blade lock can be freely rotated within the rotation range of 90 degrees after being subjected to strong vibration and impact, so that the key cannot be inserted, so the safe lock and the cabinet are locked by the blade. A plastic rod similar to the key is inserted in the hole to prevent the blade from rotating freely. Please keep this plastic rod, move, transport safe, cabinet or when unused for long periods safes, cabinets when the plastic rod inserted into the keyhole, can prevent free rotation of the blade but also prevent foreign matter into the keyhole, do both.
Pneumatic valve is a kind of valve controlled by air pressure, which is widely used in industrial automation control system. Its main applications include the following aspects:
1. Fluid control: pneumatic valve can be used to control the flow and direction of liquid or gas, such as controlling the flow in the pipeline, exhaust gas emission, etc.
2. Pressure control: pneumatic valve can be used to control the pressure of fluid, such as controlling the pressure of compressed air, regulating the pressure in the hydraulic system, etc.
3. Temperature control: pneumatic valve can be used to control the temperature of fluid, such as the temperature of heating or cooling system.
4. Automatic control: pneumatic valve can be linked with sensors, PLC and other equipment to realize automatic control, such as automatic production lines, robots, etc.
5. Safety control: pneumatic valve can be used for safety control, such as controlling emergency stop, preventing overload, etc.
In general, pneumatic valve plays an important role in industrial automation control system, which can improve production efficiency, reduce costs, and ensure safety.
