Unnecessary element is eliminated in setting 5, reduces the manufacturing cost of water system；By between booster pump 3 and outlet pipe 7 simultaneously
Join emergency filter device 5, water system realizes that two-way supplies water, i.e., leads to filter device 4 under normal circumstances and supply water, emergent or
It is supplied water by emergency filter device 5 under inspecting state, is supplied water in the specific use process using two-way due to water system,
Emergency water supply can be carried out conveniently by switching flow route or maintenance of not cutting off the water, ensure that production line is overhauled in water system
Or normal operation is remained to when partial destruction, it is easy to use.
It is provided directly with a third check valve 31, booster pump 3 and sand filter 41 in booster pump 3 and emergent sand filter 51
Between this have the 4th check valve 32, but when supplying water under normal circumstances, open the 4th check valve 32, close third check valve 31, but
When needing repairing, third check valve 31 is opened, closes the 4th check valve 32, realization filter device is cut with emergency filter device
It changes.
Above-mentioned emergent sand filter 51, emergent charcoal filter 52, emergent cartridge filter 53, nanofiltration filtering of meeting an urgent need
The structure of device 54 with sand filter 41, charcoal filter 42, cartridge filter 43, the structure one of nanofiltration filter device 44
It causes.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should be included in the utility model
Within the scope of protection.
