The knob is a hand-operated, manual-operated component. According to the functional requirements are divided into continuous rotation, the rotation angle can reach 360 °; also do positioning rotation. Classification of its shape can be divided into circular knob, multi-knob, pointer knob, manual turntable and so on.
Process Analysis of Plastic Parts (PC / ABS) with a shrinkage of 0.5%. Its external dimensions are Φ 20 × 16 mm and the average thickness is 2.5 mm. It is a kind of polycarbonate / acrylonitrile-butadiene-styrene copolymer. The internal structure of the plastic parts more complex, both the ribs, but also with the structure of the assembly, requiring good electrical insulation properties, with a certain mechanical strength, abrasion resistance, flame resistance and dimensional stability. Plastic parts of the outer surface of the structure is simple, from the die molding can be. The internal structure of plastic parts, such as by the overall punch molding, will make the punch structure of the complex to the manufacturing difficulties, while the plastic parts is not easy to mold, so consider the post-mold insert and inlay molding plastic parts for internal assembly structure. At the same time, because after the molding of plastic molding parts on the back side of the larger holding force, using a mold easy to damage the plastic parts, so consider the second release structure.

Gas electromagnetic valve is a gas pipeline safety emergency cut off device. It can be connected with the gas leakage alarm system or with the fire and other intelligent alarm control terminal module connected to achieve on-site or remote automatic / manual emergency cut off the gas source to ensure gas safety. When a strong and harmful vibration occurs, the valve automatically closes. Open the valve to be subject to manual intervention, manually open to meet the safety management practices, in line with the characteristics of accident handling.
Installation 1. Valve installation unit should have the appropriate qualification and installation of the relevant gas pipeline construction specifications. 2. Valve should be installed in the indoor after the total intake valve for maintenance. 3. The valve body should be installed in the direction of the air flow, the valve coil can not be inverted, allowing horizontal and vertical installation. 4. Solenoid valve control line should be correct and reliable connection, the control line polarity: white line for the positive black line is negative, can not be reversed. 5. Pipeline purge, it is recommended to isolate the solenoid valve, so as not to damage the debris in the valve sealing material. 6. Pipeline in the test pressure test sealing performance, should first open the valve at the state of the solenoid valve. 7. Manually open the valve, should be in the valve inlet and outlet pressure balance operation. 8. Electric valve, avoid the wrong power supply, such as: the wrong polarity, the wrong voltage or long power, so as not to damage the electromagnetic coil.

An adapter is an interface converter that can be a standalone hardware interface that allows hardware or electronic interfaces to be connected to other hardware or electronic interfaces, or to information interfaces. For example: power adapter, tripod base adapter parts, USB and serial port switching equipment.
