Description
Technical field
The utility model relates to a kind of city tap-water water supply cleaning device, is specifically related to a kind of water supply line filter.
Background technology
The domestic water of urban subscriber mainly draws rivers and lakes and underground water by the water intake pumping station of water factory, surface water, according to national Drinking Water related sanitary standard, through the process of the technological processes such as precipitation, sterilization, filtration, be transported to each user finally by Energy Saving Measures of Pumping Station and piping network.Ducted water usually again can produce impurity in the process of circulation; these impurity mainly come from the long-term deposition of impurity in a small amount of running water and are formed; and the corrosion of water supply pipe formation long neglected and in disrepair comes off block, produce after also having the ducted aqueous metamorphism of minority cyclicity difference.This wherein larger solid impurity, what may make compressor water pump or instrument normally receives impact.
In order to solve these solid impurities contained in water supply pipe, usually need, on pipeline, filter is installed, traditional filter is mainly being connected in series a cylindrical shell on pipeline, then in cylindrical shell, screen pack is placed, when running water is by after screen pack, solid impurity particle is blocked in cartridge filter, and the fluid of cleaning is by cartridge filter, discharges through outlet.Although such cartridge filter can impurity screening preferably, impurity is saved bit by bit and filter efficiency can be caused constantly to reduce on screen pack, and it is also comparatively large to change screen pack difficulty, usually needs to interrupt supplying water, and is therefore badly in need of to improve existing filter.
Utility model content
The purpose of this utility model is to provide a kind of water supply line filter, makes not only to filter running water, and better can carry out cleaning regeneration to filter.
Water supply line filter in this programme, include the connecting cylinder that two ends are provided with ring flange, this connecting cylinder is serially connected on water supply line, the middle part caliber of described connecting cylinder is greater than two ends caliber, a cylindrical filter screen is provided with in connecting cylinder, one end of filter screen is fixedly connected with the water inlet end of connecting cylinder, the current deflecting valve of a sheet is provided with in this end filter screen, the shape of current deflecting valve is identical with filter screen inner hole section, current deflecting valve is connected on the handle of connecting cylinder outer wall by valve rod, the other end of filter screen is closed and is arranged, this filter screen blind end is provided with a blow-off pipe be connected in filter screen, it is outer and by sealing of lid that the other end of blow-off pipe is arranged on connecting cylinder, a stage clip is provided with between described filter screen blind end and current deflecting valve, the external diameter apical grafting of stage clip is on the inwall of filter screen.
The water supply line filter of this programme is adopted to have following advantage: because connecting cylinder is serially connected on water supply line, and expand in the middle part of it, one end of cylindrical filter screen is fixedly connected with the water inlet end of connecting cylinder, the other end is closed and is arranged, like this when current enter from connecting cylinder water inlet end, can through filter screen, then flow away from the water side of connecting cylinder, solid-state particle is left in filter screen, owing to being provided with the current deflecting valve of a sheet in filter screen, the shape of current deflecting valve is identical with filter screen inner hole section, current deflecting valve is connected on the handle of connecting cylinder outer wall by valve rod, when filter screen is dirtier, the valve rod of current deflecting valve is rotated by handle, make current deflecting valve closure filter screen, now current can pass space between connecting cylinder and filter screen from the filter screen of current deflecting valve front end, then a part flows away from the water side of connecting cylinder, another part is through the filter screen at current deflecting valve rear portion, enter in filter screen, thus the solid granulates on filter screen is taken away, discharge from blow-off pipe, owing to being provided with a stage clip between filter screen blind end and current deflecting valve, the external diameter apical grafting of stage clip is on the inwall of filter screen, it is flexible that current deflecting valve can make stage clip occur in the process of rotating, thus the inwall of the outer wall of stage clip to filter screen scrapes, the impurity sticking to filter screen inwall is allowed to fall down, blow-off pipe is flowed into current.
Preferably, the outer wall of described current deflecting valve is provided with a silica gel sealing layer, and when such arranging can make to close current deflecting valve, the outer wall of current deflecting valve is combined with filter screen inwall more closely, thus allows the better effects if of backwash.
Preferably, described connecting cylinder outer wall is provided with the groove holding the valve rod other end, such arranging can make the fixing more firm of valve rod.
Preferably, the two ends of described stage clip bend to center, and such arranging can make the end area of stage clip larger, and current deflecting valve extruding stage clip is more easy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment water supply line filter.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises, ring flange 1, connecting cylinder 2, filter screen 3, current deflecting valve 4, valve rod 5, handle 6, blow-off pipe 7, stage clip 8.
The water supply line filter of embodiment is as shown in Figure 1: mainly include two ends are serially connected in water supply line connecting cylinder 2 by ring flange 1, the material of connecting cylinder 2 is cast iron, its end is welded with ring flange 1, the middle part caliber of connecting cylinder 2 is greater than two ends caliber, a cylindrical filter screen 3 is provided with in connecting cylinder 2, one end of filter screen 3 is fixedly connected with the water inlet end of connecting cylinder 2, the current deflecting valve 4 of a sheet is provided with in this end filter screen 3, the shape of current deflecting valve 4 is garden sheet shape, outer wall is provided with a silica gel sealing layer, the size of current deflecting valve 4 is identical with filter screen inner hole section, when can make to close current deflecting valve 4, the outer wall of current deflecting valve 4 is combined more tight with filter screen 3 inwall, current deflecting valve 4 is connected on the handle 6 of connecting cylinder 2 outer wall by valve rod 5, connecting cylinder 2 outer wall is provided with the groove holding valve rod 5 other end, the other end of filter screen 3 is closed and is arranged, filter screen 3 blind end is provided with a blow-off pipe 7 be connected in filter screen, it is outer and by sealing of lid that the other end of blow-off pipe 7 is arranged on connecting cylinder 2, a stage clip 8 is provided with between filter screen 3 blind end and current deflecting valve, the external diameter apical grafting of stage clip 8 is on the inwall of filter screen, the two ends of stage clip 8 bend to center, to make the end area of stage clip larger, current deflecting valve is made to extrude stage clip 8 more easy.
