[description of drawings]
Sectional drawing when Fig. 1 is in open mode for the utility model permanent magnetism outlet valve.
[embodiment]
See also Fig. 1, the utility model permanent magnetism outlet valve is installed on the valve seat 5, and it comprises housing 1, control piece 2, Sealing 3, first permanent magnet 4, second permanent magnet 61, spool 6 and valve pad 7.Housing 1 inside is formed with host cavity 11, and the top of this housing 1 and bottom be respectively equipped with first, second opening 12,13, and this first opening 12, host cavity 11 and second opening 13 are connected.Control piece 2 can move up and down, it cooperates with first opening 12 and host cavity 11 is stretched in the bottom of this control piece 2, in the present embodiment, the inwall of this first opening is provided with internal thread, the outer wall of control piece is provided with outside thread, make control piece be installed on first opening of housing by the screw-thread fit between this internal and external screw thread, thus can be by realizing moving up and down of control piece along being rotated counterclockwise control piece; Certainly, can screw thread be set yet and directly control piece be connected with the ball float of water tank, move up and down thereby drive control piece by ball float.First permanent magnet 4 is made by permanent-magnet material, and it is located on the outer wall 21 of control piece 2 for ring-type and adapter sleeve, and in the present embodiment, first permanent magnet 4 is a permanent-magnetic clamp.
The shape of the shape of valve pad 7 peripheries and the inwall of second opening 13 matches, and makes second opening 13 of these valve pad 7 energy seal casinghousings 1.Valve pad 7 is made by elastic material, when making this valve pad 7 be subjected to external force resiliently deformable can take place.Valve pad 7 is provided with kink 73, water intake 71 and water outlet 72, this kink 73 can increase the elasticity of valve pad 7, this water intake 71 and water outlet 72 all run through this valve pad 7 up and down, water intake 71 is communicated with the water-inlet cavity 9 of valve seat 5, water outlet 72 is communicated with the water chamber 10 of valve seat 5, and the bore of water intake 71 is less than the bore of water outlet 72.In order to increase the intensity of valve pad 7, surface attachment at this valve pad 7 has reinforcer 8, this reinforcer 8 is a plastic cement material, it is provided with the locating piece 81 of band barb 82, this locating piece 81 passes water intake 71 and water outlet 75 and detains the lower surface 75 of holding valve pad 7 by barb 82, thereby reinforcer 8 and valve pad 7 are clasped.Sealing 3 lids are established this valve pad 7, and form balance cavity 31 between sealing part 3 and the valve pad 7, and the kink 73 of valve pad 7 promptly protrudes out setting to the direction of this balance cavity 31.In the present embodiment, valve pad 7 is recessed on and is provided with locating slot, protrude out on the Sealing 3 and be provided with positioning block 32, this positioning block 32 snaps in this locating slot 71, thereby the end 76 of valve pad 7 is pushed down in the end 33 that makes Sealing 3, when valve pad 7 is subjected to external force, owing to pushing down sealed 3 of its end, so the middle part of valve pad 7 raises up.
Spool 6 is placed in the balance cavity 31 and is positioned at the top of water outlet 72, and second permanent magnet 61 is located on this spool 6, and the polarity of first, second permanent magnet 4,61 is identical.In the present embodiment, this second permanent magnet 61 is the permanent magnetism post, and the one or both ends of this permanent magnetism post are provided with cushion 62.
In the utility model, housing 1 is provided with stepped part 14, control piece 2 is provided with first groove 22 towards a side of Sealing 3, Sealing 3 is provided with second groove 34 towards a side of spool 6, this second groove 34 is the part of balance cavity 31, first groove 22 is covered with Sealing 3, and the stepped part 14 of housing 1 is pushed down Sealing 3, the second grooves 34 and is covered with spool 6.
The working principle of this permanent magnetism outlet valve is as follows: first permanent magnet 4 moves up along with control piece 2 and when moving down, according to the principle that there is a natural attraction between the sexes of repelling each other of the same sex between the magnet, second permanent magnet 61 that first permanent magnet 4 is repelled in the spool 6 moves up or down thereby drive spool 6; When control piece 2 moves up, first permanent magnet 4 repels second permanent magnet 61, spool 6 is fallen and seal water outlet 72, water-inlet cavity 9 and water chamber 10 are not communicated with, the pressure of the pressure of water-inlet cavity 9 and balance cavity 31 equates, realized the balance of water-inlet cavity 9 and balance cavity 31, valve pad 7 does not move, and outlet valve is closed; When control piece 2 moves down, first permanent magnet 4 repels second permanent magnet 61, spool 6 is moved up and leave water outlet 72, water in the balance cavity 31 flows into water chamber 10 and makes 31 pressure releases of balance cavity from water outlet 72, again because the bore of water intake 71 less than the bore of water outlet 72, so the pressure of water-inlet cavity 9 is greater than the pressure of balance cavity 31, the middle part projection of valve pad 7, this outlet valve is opened, thereby current can flow directly into water chamber 10 from water-inlet cavity 9, and the direction of current is shown in arrow among Fig. 1 in this process.
The utility model permanent magnetism outlet valve can be widely used in family and outdoor water valve, can well realize full-automatic water filling for solar water heater, high-order water storage box and cistern and not have water clock.In addition and since the utility model adopt be between permanent-magnetic clamp and the permanent magnetism post, two kinds pairs of interactive balances between balance cavity and the water-inlet cavity, make outlet valve more effectively prevent to leak.
