Install check valve is not afraid of water, in case the back of the water pollution?
The function of the check valve is to prevent water from flowing back. It is mainly installed at the outlet of the water pump to protect the water pump from reversing, so as to avoid the pump damage and mechanical accident.Usually between the water pump outlet pipe and the water tank inlet, must be equipped with check valve, to prevent water backflow!
The check valve is to prevent the backflow of water from the pipe after the pump stops. If the pipe is very large and the water is flowing back every time, isn't it a waste?If the water tank or tank pipe at the bottom of the pool, it must check valve, or a box of water will drain off, if the line is not big, the water inflow of the water is from the top of the box, it can also be installed check valve. Is not loaded with pipeline and process!
Install check valve is to prevent water in case of backflow, polluting water sources.A check valve or backflow preventer may be installed on the tap water supply pipe, which is not harmful to the system.Backflow prevention device according to tap water supply equipment, especially drinking water pipe back to serious pollution, and effectively prevent the pollution device under the condition of a strictly limited hydraulic control assembly pipeline water only one-way flow of development, its function is to prevent backflow pipeline media in any condition, in order to avoid the purpose of backflow pollution. The backflow preventer consists of low pressure backflow prevention device and vacuum type backflow prevention device two, according to the national standard of low pressure backflow prevention device of head loss is less than 3 meters, decompression type backflow prevention device of head loss is less than 7 meters.
The function of the check valve is to prevent water from flowing back. It is mainly used at the pump outlet to protect the water pump. Of course, it is also possible to prevent backwater pollution. Where to use it, mainly to function, is not necessarily to be applied in a traditional way!
