First, check the appearance of the original car before the refit, whether the near and far lights are normal, and it is necessary to further modify the original car under normal conditions. (Note that the near light will not be on when the far light is on, and the near light will be on when some of the cars are in the far light state. The far light will be on at the same time when the far light state is installed. This is a normal situation. Some models are far and near. Bright). According to the user's requirements for modification, the original car headlight control line is first unplugged, the power-on inspection instrument panel has no fault lamp alarm, and the high beam indicator is off or flashing. If normal can be directly installed next step. If the fault light or other abnormal conditions should be confirmed with the professional manufacturer before further modification.
Second, disassemble the original car halogen bulb must be very careful when dismantling, can not damage the appearance of the lamp cup and the line, check the type of halogen bulb removed and the xenon lamp model is the same. (If different models can not be modified)
Third, the fixed xenon bulb xenon lamp holder should be closely attached to the car's lamp cup, if the installation xenon lamp holder and the car's lamp cup does not closely adhere to the problem of astigmatism, the installation must pay attention, it is recommended to remove the lamp cup installation more intuitive. Note: Since the original car seat holders of some models are quite special, ordinary lamp holders cannot be fixed after installation, and the original car lamp cups need to be installed with special fixing seats. The models that need to install special lamp holders are BMW series models, 04, 05 Odyssey, Volkswagen Sagitar, Touran, New Bora and others.
4. Open a hole with a diameter of 22-25mm on the waterproof cover, pass the lead of the xenon lamp through the hole from the hole, and block the hole with a rubber ring. If the rubber ring blocks the hole and the virtual bit is large, the rubber ring must be sealed with adhesive. Note: If you remove the halogen bulb of the original car without removing the waterproof cover, you do not need to open the hole in the waterproof cover.
Fifth, the fixed ballast installed ballast as far as possible away from the car engine (such as engines, tanks, etc.), so as not to affect the ballast's life, the best location for the installation is in the bumper, headlight assembly below or beside. Note: Use a screw or mounting bracket to fasten the stabilizer when possible.
6. Connect the plug of the original vehicle socket and the input power cord of the xenon bulb, connect the plug of the stabilizer and the xenon bulb input power cable, and connect the high voltage plug of the ballast and the bulb.
Note: Dual lamp products (H4, H13, 9004, 9007) must be powered on the battery. When connecting, it is necessary to ensure that the original car's line cannot be powered off. When connecting the negative electrode to the car body, be sure to use a blade or The blade will set a new surface and make the body contact with the wire ear.
7. Check whether the xenon bulb is fixed in place; whether the waterproof rubber ring is sealed; if the ballast is stable; whether the connection is correct, the original car accessories screws are all stable, clean the installation site, so that the tools or other items are not close to the engine. Turn on the engine and check whether the power-on test light is on or not. In the determination of no adverse circumstances, the harness, lead wire with a cable tie fixed to the body, in particular, the ballast of the high pressure output line must be fixed to the body of the car, so as to avoid the high frequency vibration of the car in the work of causing the disconnection And the ballast cannot work.
Eighth, electricity test Open the engine, adjust the lamp lighting, check the light is correct, do a good record of installation, ready for the next installation or maintenance inspection.
Globe valve, also known as cut-off valve, is a mandatory sealing valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from under the valve disc, the resistance that the operating force needs to overcome is the friction force between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve stem The diameter of the valve should be large, otherwise the failure of the top of the valve stem will occur. According to the connection method, it is divided into three types: flange connection, thread connection and welding connection. After the appearance of the self-sealing valve, the medium flow direction of the globe valve is changed from the top of the valve disc into the valve cavity. At this time, under the action of the medium pressure, the force to close the valve is small, but the force to open the valve is large, and the diameter of the valve stem can be adjusted accordingly. decrease. At the same time, under the action of the medium, this form of valve is also tighter. my country's valve "Three Chemicals" once stipulated that the flow direction of the globe valve should be from top to bottom. When the globe valve is opened, the opening height of the valve disc is 25% to 30% of the nominal diameter. The flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the globe valve should be determined by the stroke of the valve disc.
