Abstract
The utility model relates to a leading style electromagnetic water valve with a filtering net, which comprises an electromagnetic drive mechanism, a guiding valve, and a main valve. The seat of the guiding valve is fixed on the film of the main valve; the outlet and the inlet of the guiding valve are respectively arranged at the center and the outside circle. The utility model is characterized in that a ring filtrating net with a cross section of a groove type is arranged at the inlet of the guiding vale and the circle where the guiding valve is positioned. The utility model has the advantages of reasonable structure and safety for operation. The filtrating net can be free of cleaning.
Description
The utility model relates to the electromagnetism water valve.More particularly, be a kind of leading type electromagnetism water valve.
Leading type electromagnetism water valve is made of electromagnetic drive mechanism, pilot valve and main valve.Electromagnetic energy only need be controlled the unlatching of pilot valve or close, and is induced the keying of main valve again by pilot valve, thereby reaches the effect of " four liang are pulled out very heavy ".In this structure, a large amount of current have only very a spot of current through pilot valve through main valve.And the water yield of the pilot valve of flowing through is few more, and the required energy of Electromagnetic Control is promptly more little.Thereby pilot valve is gone into, water outlet all designs as far as possible for a short time.So, pilot valve is not as taking appropriate filtration measure, in case the arbitrary aperture in the intake-outlet is stopped up by the grit in the water, pilot valve lost efficacy immediately, caused whole valve out of control.So filter screen is indispensable parts in the leading type electromagnetism water valve.Because the narrow space of pilot valve inlet is difficult to directly install filter screen.Common way is in the main passage of valve filter screen to be installed, and the water yield is carried out hundred-percent filtration treatment.Like this, in the relatively poor environment of water quality, not only filter screen often will clean, trouble very, and because to take, put filter screen improper unavoidably sometimes, and bleeding to grit has had opportunity, becomes the important hidden danger that pilot valve lost efficacy.Another kind of way is that pilot valve water channel and main valve are separated, and makes the pilot valve inlet that narrow enough installation filter screen be arranged, and significantly reduces the water yield that needs filtration.Like this, almost can accomplish to exempt to clean filter screen.But this split pilot valve structure is a cost to increase the valve volume.This reduces in the product (as integrated induction tap) of volume at needs as far as possible is to adopt.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, provide a kind of simple in structure, volume is little, the leading type electromagnetism water valve of the band filter screen of reliable operation.
The purpose of this utility model is achieved through the following technical solutions:
The utility model is made of electromagnetic drive mechanism, pilot valve and main valve, and guide's valve seat connects firmly on the main valve film, and the pilot valve outlet is positioned at central authorities, and the pilot valve inlet is positioned at periphery.
Structural feature of the present utility model is corresponding to the pilot valve inlet ring-type filter screen to be set, and described ring-type filter screen cross section is a groove shaped, and this groove shaped ring-type filter screen be located on pilot valve inlet and the residing circumference thereof.
Compared with the prior art, the utlity model has following advantage:
1, the employing of ring-type filter screen in the utility model, expand the filter space of pilot valve water inlet to greatest extent, be implemented in the pilot valve water inlet filter screen directly is installed, increased filter capacity greatly, greatly prolong the life time of filter screen, exempted the trouble of cleaning filter screen.
2, the utility model need not to change the structural type of original guide's valve seat, and the valve usability is not affected.
3, groove shaped ring-type filter structure of the present utility model is tight, and reliable operation can guarantee effectively to filter, its simple installation, and highly versatile, easy to utilize.
Fig. 1 is the utility model general structure schematic representation.
Fig. 2 is the utility model filter structure schematic representation.
Fig. 3 is Fig. 2 A-A sectional drawing.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to Fig. 1, present embodiment is made of electromagnetic drive mechanism, pilot valve and main valve.Guide's valve seat 1 connects firmly on main valve film 2, and pilot valve outlet 3 is positioned at central authorities, and pilot valve inlet 4 is positioned at periphery.
Referring to Fig. 1, Fig. 2, in the present embodiment, ring-type filter screen 5 is set corresponding to pilot valve inlet 4, these ring-type filter screen 5 cross sections are groove shaped, groove shaped ring-type filter screen 5 be located on pilot valve inlet 4 and the residing circumference thereof.
Referring to Fig. 2, Fig. 3, for filter screen 5 is installed, in the present embodiment, setting is similarly the filter screen seat 6 of annular recess shape, filter screen 5 is nested with filter screen seat 6 make-ups, other has rivet 7 to pass filter screen 5, filter screen seat 6 and main valve film 2 successively to be fixed on guide's valve seat 1, makes filter screen 5, filter screen seat 6, main valve film 2 and guide's valve seat 1 form integrated linkage structure.Fig. 2 illustrates, and establishes four rivets 7 altogether, and is uniform along ring-type filter screen 5.
In addition, present embodiment has Electromagnetic Drive structure and the course of action identical with prior art.Its guide's spool 8 connects firmly in the bottom as the moving iron core 9 of valve rod.
In the opening process, moving iron core 9 rises, and drives guide's spool 8 and mentions, and pilot valve outlet 3 is at first opened, and the current that flow in the pilot valve inlet 4 at first obtain filtering in ring-type filter screen 5.Pressure medium in guide's valve pocket reduces thereupon.Since the pressure medium among the main valve inlet A, 2 arches of main valve film, main valve outlet B is communicated with main valve inlet A, and valve is opened.
Close in the closed procedure, moving iron core 9 falls, and guide's spool 8 is closed pilot valve outlet 3, and at this moment, because pilot valve inlet 4 is communicated with main valve inlet A, the pressure medium in guide's valve pocket presses down main valve film 2, and main valve outlet B is closed then with the passage of inlet A.
