Fig. 1 is the utility model structural representation.

Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.

Sleeve seal formula leakproof valve comprises T-valve body 1, water supply connector 2, water output connector 3, spool, valve rod 4.Spool is made up of the movable valve plug 5 and the quiet spool 6 of disc, movable valve plug 5, have the fan-shaped water port of pair of corresponding on the quiet spool 6, there is coupling shaft 7 at movable valve plug 5 one side centers, one section driving cog 8 is arranged on the top periphery, there is circular hole at quiet spool 6 centers, the fixed plate 9 that three protrusions are arranged on the periphery, after coupling shaft 7 on the movable valve plug 5 passes quiet spool 6 center holes, make by the spring 10 and the snap ring 11 that are enclosed within on coupling shaft 7 rearward end, quiet spool is close to and is combined into spool, spool is inserted in the waterexit end of valve body 1, screw in valve body 1 with on the step of fixed plate 9 roof pressures in valve body 1 on quiet spool 6 peripheries by water output connector 3, water supply connector 2 is threaded with valve body 1, advances, water output connector external port inwall has connecting thread.Valve rod 4 is the little stepped shaft broad in the middle in two, there is circular groove at the middle part, the bottom is connected with the plate gear 12 of diameter less than following shank diameter, inserting valve body 1 places on the interior step, the plate gear 12 of bottom and 8 engagements of the driving cog on the movable valve plug 5, the valve gap 13 that is threaded with valve body 1 is stretched out in the upper end, and in the circular groove at valve rod 4 middle parts, quiet spool 6, valve gap 13 are with seal ring respectively with valve body 1 joint.Inner handle 14 is the cylindrical shape of making of permeability magnetic material, and the bonding one deck permanent magnet 15 of outer side surface piecemeal has fixing rod 16 between the inboard, the square hole at fixing rod 16 centers is inserted on the square platform on valve rod 4 tops fixedly connected, gapped between lower end and the valve gap 13.Leak jacket 17 is the cover cap shape of making of non-magnet material, there is outer flanging the lower end, and cover cap is on inner handle 14 with a gap, and outer flanging places on 13 limits of valve gap, be fixed on the valve gap 13 with fixed card 18, bolt 19, outer flanging and valve gap 13 joints are with seal ring.Outdoor handle 20 is the cover cap shape of making of permeability magnetic material, there is interior flanging the lower end, bonding one deck of inner side surface piecemeal and the identical different pole permanent magnet 21 of inner handle 14 outer side surface permanent magnets 15 quantity, cover cap is on leak jacket 17 with a gap, the bottom surface of valve gap 13 peripheries is gone in the invagination checkpost, and upper and lower round angle place is with L shaped positioning ring 22 respectively.

The utility model is owing to adopt above design, when outdoor handle 20 moment effect is outside rotated down, because the magnetic attraction effect of its inner side surface permanent magnet 21 and inner handle 14 outer side surface permanent magnets 15, inner handle 14 and then rotates, transmission by valve rod 4, movable valve plug 5 is rotated, with valve opening or close.Because leak jacket 17, valve gap 13 and valve body 1 are connected as a single entity, and have fundamentally solved the problem of leaking outside, it is little to wear and tear, and long service life is suitable for various media and uses.
