Description

A kind of push key type water tap

Technical field the invention belongs to a kind of of valve, especially a kind of water tap.

The background technique magnetic control valve, the fire hose is first-class all is the switch of controlling spool by magnetic force indirectly, is a kind of non-contact type control, and biggest advantage is that medium can not leak from valve handle.In such technology, especially the patent No. with the claimant is: 99252886.0, name is called: " a kind of Magnetic control valve parts ", and the patent No. is: 02234173.0, name is called: " a kind of gooseneck type magnetic control water tap " two patent documents are detailed especially to this type of technology elaboration, except comprising Figure of description, in specification, this class technology has been done fully openly in the patent document, do not explained in addition at this.

The model utility content is in existing ordinary faucet technology, there is a problem can't solve always, Here it is when water tap discharges water with the speed of drip, existing civilian measure water-meter all can not be metered into, though the water of a water tap loss is not very many, but when finally being reflected on total water meter of tap water supply side, this number is just quite surprising.Address this problem from technological layer and consider still to be relatively more real.At first to design a kind of water tap that does not have intermediateness, has only standard-sized sheet or complete shut-down two states, can not occur can the minimum velocity water outlet state, solved this technical problem from structure.It can adopt in the following technological scheme any:

One, faces a side of valve core housing at valve body, by upright dividing plate, connect in the cavity that base plate, button sheath three parts form the button of adorning magnet in one be installed, between button and connection base plate, a spring is housed, a positive stop hook is housed in the annular slide track of button.Button is the square cylinder that there is the edge upper end, front in the Lower Half of square cylinder has an arch inner groovy, the front of arch inner groovy is processed a sub-circular slideway once more, there is an inwardly prominent guiding point upper edge of annular slide track, the following anchor ring of annular slide track holds stepped, and the centre of annular slide track is the guide table of an arrow-shaped projection.About two blocks of magnet in the button hold, side by side, and the two magnetic pole holds in the magnet chamber that oppositely is contained in separately.The anchor ring of annular slide track presents following rule and distributes: a face, b face, c face, d face reduce one by one; Under the e face high low, i.e. d ₁Face is higher than the d face; And e ₁The last relative superiority or inferiority of face is low; d ₁Face is higher than adjacent a ₁Face.Positive stop hook is right angle " U " shape, and the upper end of positive stop hook places in the annular slide track, and the lower end is installed in the dog hole that connects the base plate leading edge.

Two, on the epitaxy part of valve body one side valve core retainer plate, be provided with push-boutton hole, and be installed with the magnet key that a limited nail control energy straight line moves within it.

Have a spacing slideway on the magnet key, the upper dead center of spacing slideway is positioned at the center of top magnet, and lower dead centre is positioned at the center of following magnet.

By above two technological schemes as can be known, two magnet like poles repel each other the control spool when closing, and can only be Close Alls; Otherwise also can only be the complete opening spool, because two blocks of magnet in case in the magnetic force distance with interior or adhesive closely contacts, repel each other beyond decisive range, do not have other intermediateness and distance existence, so can solve the problem that drip is stolen water by one of above technological scheme.

Description of drawings Fig. 1 is the sectional drawing of scheme one along center line, and Fig. 2 is the left view of button 13, and Fig. 3 is an A-A face sectional view, and Fig. 4 is a M-M face sectional view, and Fig. 5 is a B-B face sectional view, and Fig. 6 is the worm's eye view of Fig. 1, and Fig. 7 is the sectional view of scheme two along center line.

Embodiment embodiment one: a connecting plate 24 is arranged below valve body 21, fix both by screw hole 23, with dividing plate 14 of connecting plate 24 one and perpendicular to being connected base plate 24, in the front end of valve core housing 17 of dress magnet 16 be assemblied in the spool bore 14.1 on the dividing plate 14, a part that connects base plate 24 extend to button 13 below, it and dividing plate 14, button sheath 1 three surround and form a cavity that button 13 is installed.Button sheath 1 and dividing plate 14, be connected base plate 24 linkage structure as shown in Figure 6, rely on joint tongue 25 to cooperate to form between them and be connected with tongue-and-groove 26.Being provided with a spring 10 and erectility below the button 13 installs, there are two polarity that are installed in parallel in the magnet chamber 2 to be reverse magnet 3,9 in the button 13, there is button the upper end along 12, be provided with the groove part 4 of an arch in the front of button 13, the front of magnet 3,9, its shape as shown in Figure 2.Be processed with the annular slide track 5.1 that a plaque goes in ring on the lower plane of groove part 4, the upper edge of this slideway is provided with a guiding point 5.2, is a sagittate guide table 7 in the middle of this slideway.Distributing from high to low on the bottom surface of annular slide track 5.1 a, b, four mutual stepped faces of c, d, its regularity of distribution is shown in Fig. 3～5: i.e. d ₁Face is higher than the d face; a ₁Face is higher than a face; d ₁Face is higher than adjacent a ₁Face, the upper end of positive stop hook 6 can only be done counterclockwise to move along annular slide track 5.1 like this.When button downwards on time, the upper end of positive stop hook 6, from the lower dead centre 8 of annular slide track 5.1, along the right side of annular slide track 5.1 from a ₁Slide into the b face, when button 13 was upspring by spring 10, the upper end edge b face of positive stop hook 6 dropped into upper dead center 7.1 places that the c face enters into guide table 7 at last.At this moment the position of button 13 as shown in Figure 1, magnet 16 is repelled by magnet 3, spool 19 is shut by the sealing gasket 18 of magnet 16 front ends, water tap is in closed condition.When pushing button once more 13 the time, the upper end of positive stop hook 6 slides to the left side of guiding point 5.2, the upper end of c face, the upper end of d face successively; When unclamping button 13, button 13 is upspring once more, and position-limited nail 6 is slipped to a from d face upper end ₁The place is lower dead centre 8 places of annular slide track.At this moment, magnet 9 and magnet 16 over against because opposite pole inhales mutually, magnet 16 is inhaled to spool 19 by magnet 3, water tap is opened, and there are flowing out.

Embodiment two: as shown in Figure 7, the structure of valve body 21 and embodiment's one basically identical, just difference is that the front end of spool 17 extends to outside the valve body 21, and be provided with a push-boutton hole 1.1 thereon, also be that two blocks of arranged side by side and opposite magnet of magnetic pole are installed in the magnet key 13.1, as a same embodiment.The limited nail of magnet key 13.1 6.1 is spacing, and it can only do moving up and down of translation, and magnet key 13.1 is provided with spacing slideway 5.3, and the upper dead center of spacing slideway 5.3 is the center of magnet in the above, and lower dead centre is the center of magnet below.Magnet key 13.1 just can be done in push-boutton hole 1.1 like this and move up and down, thereby realizes the control to water tap.
