When the winter temperature approaches zero, the water supply pipeline will freeze. The water supply pipelines for residential vehicles also face the same problem. When the living water supply pipelines of vehicles are cracked, the normal life order of the whole vehicle will be plagued. In order to prevent the water pipes of the RV from being frozen, the first thing that needs to be done is to cut off the water heater power supply of the vehicle. When checking the next work, it is necessary to ensure that the water tank of the water heater is intact and in a state of heated water. under. The exhaust valve is opened by the resident car with the exhaust valve. If there is no exhaust valve, the plug is pulled out. In order to accelerate the speed of drainage, the pressure relief valve can be opened first to allow smooth circulation of air and to break the vacuum state of the hot water tank of the vehicle. Wait until the water in the water tank is exhausted, and then close the exhaust valve and the safety valve of the RV. The water discharge in the clean water tank and the water heater can be operated together. After the water in the clean water tank is almost completely eliminated, all the water remaining in the water connection pipe needs to be wiped clean, and then it is disassembled and stored. it is good. After the water in the tank is completely drained, antifreeze measures can be started. There are two ways to prevent freezing. One is to use an anti-freeze agent to fill all the water supply systems of the RV. The second is to use air to completely remove the water from the pipeline. In fact, use the second one. The freezing method is more economical. Then, the car owners must pay attention to the purchase of antifreeze. Do not substitute the antifreeze used in the vehicle for the antifreeze in the water supply system in order to take advantage of the low cost or ease of use. This is not worth the loss. . Then adjust the water heaters of the RVs to the splitters. After pouring the antifreeze into the clean water tanks and pouring the antifreezes down, turn on the water pump in the RV and the equipment that is playing with the water. There is liquid coming out of the tap. After preparing for this precautionary preparation, close the pump again. Then adjust the air pressure of the air compressor of the RV to 40 lbs, which can prevent it from blowing the piston valve of the water pipeline. If the air compressor of a residential vehicle is capable of being adjusted, a blocking device should be added to the water supply pipe and air pipe for a long time. Next, turn the water heater into a diversion and pour antifreeze into the water tank or install a pump anti-freeze directly. After the antifreeze is put in place, turn on the water pump and all the water-related RV equipment, knowing that there is liquid dripping from the faucet. After completing this work, close the pump. Adjusting the air compressor pressure to 40 pounds will effectively prevent it from blowing the piston gate valve of the water pipeline. If the air compressor cannot be adjusted, a blocking device should be added between the air pipe and the water supply pipe. In addition, the above steps are repeated in the grey water tank and the black water tank for antifreeze treatment. As for the anti-ventilation valve and the toilet, it is best to add some antifreeze. Our product lines cover all series of stepper motor since NEMA8/20mm to NEMA42/130mm.
