The specific embodiment
Specific embodiment of the invention scheme is as follows: as shown in Figures 1 to 6, of the present inventionly exempt to unpick and wash filter and comprise filter body 1, described filter body 1 top is provided with valve pocket, in described valve pocket, be provided with spool 3, described spool 3 comprises base 30 and is located at the valve rod 31 of base 30 tops, and described valve rod 31 is connected with handle 6.Described spool 3 is driven and is rotated by valve rod 31, on described filter body 1, be provided with a water inlet 11, one delivery port 12 and a sewage draining exit 13, in described spool 3, be provided with filter chamber, in filter chamber, be provided with screen pack, inlet side 3011 and the outlet side 3021 of filter chamber are positioned at screen pack both sides, valve rod 31 band movable valve plugs 3 rotate filter are changed between filtration condition and blowdown state, at filter during in filtration condition, the inlet side 3011 of filter chamber is communicated with water inlet 11, the outlet side 3021 of filter chamber is communicated with delivery port 12, at filter during in blowdown state, the outlet side 3021 of filter chamber is communicated with water inlet 11, the inlet side 3011 of filter chamber is communicated with sewage draining exit 13.
Further, described filter chamber is located in base 30 bottoms, described filter chamber inside is divided into ante-chamber 301 and back cavity 302 by screen pack, the inlet side 3011 of filter chamber is positioned at ante-chamber, outlet side 3021 is positioned at back cavity, described ante-chamber 301 and back cavity 302 circumferentially arrange along base 30 bottoms, ante-chamber 301 and back cavity 302 bottoms are uncovered, described back cavity 302 is sealed by screen pack 303, described filter body 1 is provided with an intake antrum below base 30, described filter body 1 side is provided with a water inlet 11 and is communicated with intake antrum, described filter body 1 is upwards provided with delivery port 12 and sewage draining exit 13 week corresponding base 30 present positions, and be provided with a water chamber and be communicated with delivery port 12, described filter body 1 is provided with a blowdown chamber 10 and is communicated with sewage draining exit 13 below base 30.Delivery port 12 and sewage draining exit 13 arrange higher than water inlet 11.Described screen pack 303 is comprised of side filter screen 304 and bottom surface filter screen 305, and described bottom surface filter screen 305 is vertical with side filter screen 304, is provided with the positioning step that side filter screen is installed in the filter chamber of spool.In order to seal, between described base 30 bottom surfaces and valve pocket bottom surface, be provided with sealing ring 2, the uncovered opening that arranges in sealing ring corresponding intake antrum top, side filter screen 304 intercepts between ante-chamber 301 and back cavity 302, bottom surface filter screen 305 seals under filtration condition and between sealing ring 2, under blowdown state, intercept between back cavity 302 and intake antrum.
Described intake antrum, ante-chamber 301 and back cavity 302 cross sections are 120 degree fan shape.Described water inlet 11, delivery port 12, sewage draining exit 13 are in filter body upwards interval 120 degree settings in 1 week.Like this, spool 3 rotates after 120 degree, and ante-chamber 301 and the back cavity 302 uncovered shapes in bottom are the uncovered shape in corresponding intake antrum top just in time also, and water route is communicated with, and filter just can be changed between filtration condition and blowdown state.
Described base 30 tops are provided with gland 4 and compress, and gland 4 bottom surfaces are provided with a circle and compress boss 40 so that compress more reliable simultaneously.Be threaded clamp nut 5 of described valve pocket upside compresses glands 4.Described valve rod is square column, and insert in the slot of handle bottom described valve rod upper end.Described valve rod upper end is integrated by locking nut 7 and handle locking, between described locking nut and valve rod upper end, is provided with pad 8.
As shown in Figure 2, when handle rotation 120 degree make valve core rotation arrive filtration condition, the sewage of coming in from water inlet, filters through screen pack, and clean water flows out from delivery port, completes like this filtration to water.
As shown in Figure 3, when handle turns over 120 degree again, when making valve core rotation arrive blowdown state, now the bottom surface filter screen of screen pack bottom is transferred to intake antrum place, and side filter screen has forwarded sewage draining exit place to.At this moment by the bottom surface filter screen of screen pack bottom by the sewage at intake antrum place after filtering, recoil back in filter screen, to play the object of washing filter screen, simultaneously by the dirt originally filtering down, filter screen recoils away from the side, then from sewage draining exit, sewage is discharged, complete the process of cleaning blowdown, reach and need not dismantle the object that also can clean blowdown.
Certainly, also intake antrum can be set, and water inlet 11 delivery ports 12 and sewage draining exit 13 are all arranged at base 30 weeks laterally, corresponding with ante-chamber 301 and back cavity 302 positions.Like this, at filter during in filtration condition, ante-chamber 301 bottoms are directly communicated with water inlet 11, back cavity 302 sides are directly communicated with delivery port 12, sewage enters ante-chamber 301 from water inlet 11 is come in, and then filter through filter screen 303, clean water from delivery port 12 out, completes the filtration to sewage.At filter during in blowdown state, back cavity 302 sides are directly communicated with water inlet 11, and ante-chamber 301 sides are communicated with sewage draining exit 13, the water flushing-back filtering net 303 that water inlet 11 is come in, the dirt originally filtering down is rushed to sewage draining exit 13 and discharge, reach and need not dismantle the object that also can clean blowdown.
Above-described embodiment is to specific descriptions of the present invention; only be used to further illustrate the present invention; can not be interpreted as limiting the scope of the present invention, within the technician of this area makes some nonessential improvement according to the above-mentioned specific embodiment to the present invention and adjusts and all to fall into protection scope of the present invention.
