Detailed Description

The invention will be further described with reference to the following specific embodiments:

referring to fig. 1 to 3, a filter device for water supply equipment comprises a main water inlet pipe 1, four branch water inlet pipes 2, a filter screen 5 and a water outlet pipe 6, wherein every two branch water inlet pipes 2 are connected end to end, the two branch water inlet pipes 2 at the head end are connected with the main water inlet pipe 1, the two branch water inlet pipes 2 at the tail end are connected with the water outlet pipe 6, two first stop valves 41 are respectively arranged at the head sides of the two branch water inlet pipes 2 at the head end, two drain pipes 32 are respectively arranged at the downstream of the two first stop valves 41, two second stop valves 42 are respectively arranged at the tail ends of the two branch water inlet pipes 2 at the tail end, and two backwashing pipes 31 are respectively arranged at the upstream of the two second stop valves 42; the water inlet branch pipes 2 connected in pairs are also provided with a filter screen 5, the filter screen 5 is of a circular structure, two bosses 51 in an annular structure are respectively formed on the front side surface and the rear side surface of the filter screen 5, two grooves 21 in an annular structure are respectively formed at the connection part of the two water inlet branch pipes 2 connected end to end, the two bosses 51 and the grooves 21 are mutually clamped, and meanwhile, the two bosses 51 are respectively sleeved with two rubber rings 52 (the rubber rings 52 are used for preventing water leakage and preventing water from leaking from the connection part between the two water inlet branch pipes 2 connected end to end).

Wherein, two third stop valves 43 are respectively arranged on the two sewage discharge pipes 32; the two backwashing pipes 31 are respectively provided with two fourth cut-off valves 44, the two third cut-off valves 43 and the two fourth cut-off valves 44 are respectively in a closed state, and the two first cut-off valves 41 and the two second cut-off valves 42 are respectively in an open state in normal water supply.

Two flanges 22 are respectively sleeved at the joint between the two water inlet branch pipes 2 which are connected end to end, and the two flanges 22 are mutually connected and fixed by matching nuts and bolts.

In this embodiment, two water inlet branch pipes 2 of end to end make up into a flow pipe, be provided with two flow pipes in this embodiment, water can be followed water inlet main pipe 1 and flowed to drain pipe 6 supply user respectively through two flow pipes and use, and after two filter screens 5 used a period, can gather many impurity on the filter screen 5, thereby block up filter screen 5 and influence the normal flow of water, influence normal water supply, still can pollute the running water, consequently need regularly wash or change filter screen 5, wherein the cleaning process of filter screen 5 specifically is: firstly, closing a first stop valve 41 and a second stop valve 42 which is positioned in the same branch pipe with the first stop valve 41 to stop the running water from passing through the branch pipe, and normally supplying water to the other branch pipe, so that the normal water supply cannot be influenced, then respectively opening a third stop valve 43 and a fourth stop valve 44 in the branch pipe in which the water supply is stopped, inputting cleaning liquid, clear water and the like for cleaning the filter screen 5 into the backwashing pipe 31 to flush the filter screen 5, discharging impurities and the cleaning liquid after flushing from the drain pipe 32, finally closing the third stop valve 43 and the fourth stop valve 44, and opening the first stop valve 41 and the second stop valve 42 to finish the cleaning of the filter screen 5 in one branch pipe; the cleaning process of the other branch pipe is the same as the above process.

When the filter screen 5 needs to be replaced, the operation process is similar to the cleaning process, the first stop valve 41 and the second stop valve 42 of one of the branch pipes are closed, then the nuts are unscrewed, the two flanges 22 are detached, the boss 51 is withdrawn from the groove 21, and the rubber ring 52 is detached, so that the filter screen 5 can be detached and replaced.
