Embodiment

Combine accompanying drawing and specific embodiment that the utility model is further specified at present.

With reference to figure 1, Fig. 2, present embodiment discloses a kind of magnetic locking ball valve, comprises valve body 1, valve gap 11, spheroid spool 2, valve rod 3; Said valve body 1 upper edge axial component is provided with water intake 12 and water outlet 13, and said valve gap 11 is located on the valve body 1 left side water intake, said spheroid spool 2 rotatable being installed between valve body 1 water intake and the water outlet; This spheroid spool 2 is provided with the fluid latus rectum 21 that is connected with entery and delivery port; Said valve body 1 upper side wall extends a stem bearing 14, and the stem bearing 14 that an end of said valve rod 3 passes valve body 1 upper side wall links to each other with spheroid spool 2, comprises that also the magnetic of the magnetic block of valve 4 and the control magnetic block of valve 4 lockings unblanks to take turns 5; Offer annular arc groove 141 on the periphery wall of said stem bearing 14; The said magnetic block of valve comprises outer cover 41 and inner cover 42, offers 4 spherical pores 421 on the madial wall of said inner cover 42 and the stem bearing 14 annular arc grooves 141 corresponding positions, and ball 422 is housed in each spherical pore; The diameter of said spherical pore 421 makes the ball can be movable in spherical pore greater than the diameter of ball 422; But can not the separable spherical hole, the external diameter of said ball 422 is greater than the sidewall thickness of inner cover 42, when the magnetic block of valve is in the lock state; Ball in the inner cover is under the roof pressure of the madial wall of outer cover; The part protrusion inner cover of ball is embedded in the annular arc groove of valve body stem bearing, makes the whole magnetic block of valve can not break away from lock body, the below that said outer cover 41 madial walls are positioned at ball 422 has annular cavity 411; On outer cover, move; Outer cover 51 annular cavities 411 are during over against the spherical pore 421 of inner cover 42, but in the part retraction annular cavity 411 of ball, also are provided with magnetic lock device between said inner cover 42 and the outer cover 41; Said magnetic lock device is on inner cover 42 that end periphery wall away from valve body, to be arranged with 2 lockholes 423; Have annular groove 412 on said outer cover 41 and the inner cover 42 lockholes 423 corresponding positions, magnetic 6 and Returnning spring 7 are housed in the said lockhole 423, said magnetic 6 free ends resist in outer cover 41 annular grooves 412 through Returnning spring 7; Make outer cover 41 not move relative to inner cover 42; Said magnetic is unblanked to take turns 5 and is provided with the magnet (not shown) identical with magnetic 6 magnetic, and said inner cover 42 is away from being laid with 6 springs 43 between that free end of stem bearing 14 and outer cover 41 madial walls, and two free ends of said each spring 43 resist respectively on the madial wall of the free end of inner cover 42 and outer cover 41; When not having magnetic to block outer cover, the elastic force through spring 43 can make outer cover 41 along axially upwards slippages of inner cover 42.

Said magnetic block of valve inner cover 42 is positioned on periphery wall and outer cover 41 annular grooves 412 opposite positions of lockhole 423 tops and also is arranged with two pin-and-holes 424; Locating stud 8 and Returnning spring 9 are housed in the said pin-and-hole 424; The free end of said locating stud 424 resists in outer cover 41 annular grooves 412 through Returnning spring 9, and said lockhole is to intersect up and down with pin-and-hole and is uniformly distributed with.Through this structure, can prevent that outer cover 41 breaks away from inner cover 42.

The free end of said valve rod 3 is provided with square protruding 31, and said magnetic is unblanked to take turns 5 and is provided with and the corresponding square open keyhole 51 of valve rod 3 square convexities.After the magnetic block of valve took off from valve body, protruding 31 rotary valve rods of square that the square open keyhole that magnetic is unblanked to take turns is aimed on the valve rod got final product Open valve.

When the magnetic block of valve was in the lock state, the ball in the inner cover was embedded in the annular arc groove 141 of valve body stem bearing the part protrusion inner cover of ball under the roof pressure of the madial wall of outer cover; Make the whole magnetic block of valve can not break away from lock body, when needing Open valve, magnetic unblanked to take turns being sheathed on the magnet valves side of locking and pushing and make the magnet of magnetic in unblanking to take turns corresponding with the magnetic position of the magnetic block of valve; Because of the magnetic pole of the magnetic of magnet and the magnetic block of valve of magnetic in unblanking to take turns is a homopolarity, under the effect that the magnetic homopolarity repels mutually, the magnetic of the magnetic block of valve produces in the complete retraction lockhole of pressure connected Returnning spring; Make magnetic block of valve outer cover to move relative to inner cover, simultaneously outer cover rises under the effect of spring 43, until its annular cavity during over against the spherical pore of inner cover; When ball does not receive the roof pressure part retraction outer cover annular cavity of outer cover madial wall, just can the whole magnetic block of valve be taken away from valve body, after the magnetic block of valve takes off from valve body; Protruding 31 rotary valve rods of square that the square open keyhole that magnetic is unblanked to take turns is aimed on the valve rod get final product Open valve; Behind the end of operation, put the magnetic block of valve, then; Push the magnetic block of valve; Annular cavity on the outer cover madial wall is moved down, makes ball be embedded in the annular arc groove of stem bearing, make simultaneously inner cover lockhole and outer cover the annular groove position over against; Magnetic in the lockhole makes magnetic be stuck between the inside and outside cover under the effect of Returnning spring, can this ball valve be locked.

The utility model magnetic locking ball valve has the Magnetic Induction anti-theft feature; Administrative staff can realize the locking to the magnetic block of valve through the control that magnetic is unblanked to take turns, and magnetic unblanks to take turns the open and close structure of having protected valve body with the magnetic block of valve simultaneously, have the function that the restriction ball valve opens and closes operation; Guarantee the keying of personal management's ball valve; Be convenient to public utilities and community's property management, make the allotment and planned the carrying out of conveying of the energy, practiced thrift the cost of use and the energy.In addition, the magnetic block of valve of this novel magnetic locking ball valve is that full-closed structure is located on the stem bearing of valve body upper side wall, and other people can be bored by voidlessness, has effectively prevented the illegal unlatching of valve; Simultaneously, can stop that again sand and dust, rainwater get in the lock body, it is impaired that valve is difficult for, and prolonged the working life of this novel magnetic locking ball valve.

The above record is merely the embodiment who utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
