Magnetic lock ball valve, as shown in Figure 1 to Figure 3, it is the ball-valve structure of a kind of carrying magnetic lock, is mainly made up of structures such as valve body 1, valve gap 2, valve seat 3, ball valve core 4, valve rod 5, handle 7, spacing collar 8 and unlatching handwheels 9.
It is provided with, in described valve body 3, the valve pocket that level as shown in Figure 1, Figure 3 is through, can be used for the medium conveying in pipeline；The valve gap 1 that thread seal connects it is provided with in described valve body 3 right output port, this valve gap is hollow structure, the valve seat 2 sealing setting-in is set between valve gap 1 and valve body 3, and in valve seat, it is provided with the ball valve core 4 of rotary seal supporting, this ball valve core is provided with the through limbers of level 41, so that opening and closing valve pocket with the rotation of ball valve core 4, it is provided with flat groove at ball valve core 4 end face.
Described valve body 3 top is provided with upwardly extending installation base 31, the installing hole 32 being through in valve pocket along the rotational axis line of ball valve core 4 it is provided with in the middle part of this installation base, in installing hole, it is provided with vertically-mounted valve rod 5, between this valve rod 5 and installation base 31, is provided with the dynamic seal that two pass "O"-ring 6 rotates as valve rod 5；Described valve rod 5 is inner, namely lower end shown in Fig. 1 be provided with flat axle 51, this flat axle is fitted in the flat groove of ball valve core 4 to constitute being in transmission connection between valve rod 5 and ball valve core 4；Valve rod 5 outer end, i.e. upper end shown in Fig. 1 also are provided with flat axle 51, this flat axle stretches out installation base 31 and is connected with handle 7, and by alignment pin 71 make between the two connect further fixing, therefore operation handle 7 can drive ball valve core 4 to realize rotating and open and close through valve rod 5.
The installation base 31 at described valve body 3 top is respectively provided on two sides with spacing hole 33, two spacing holes are symmetrical arranged centered by installing hole 32, namely centered by valve rod 5, in two spacing holes 33, it is respectively arranged with limit spring 10 and spacing magnetic piece 11, and makes elasticity upwards pushing tow by the elastic force of limit spring 10 and make spacing magnetic piece 11 stretch out spacing hole 33 and expose；The lockhole 34 of the connected axial line side being additionally provided with on described installation base 31 between two spacing holes 33, specifically lockhole skew be arranged between two spacing holes 33 be connected axial line 45 ° of angles, in lockhole 34, it is provided with locking spring and locking magnetic piece 12, and is made elasticity upwards pushing tow by locking spring and make locking magnetic piece 12 stretch out lockhole 34 and expose.
Described installation base 31 is arranged over the spacing collar 8 being sleeved on outside valve rod 5, is provided with double; two flat departments centre bore 85, and is fitted on the flat axle 51 of valve rod 5 upper end by this pair of flat department centre bore in the middle of this spacing collar, so operate with valve rod 5 and synchronous axial system；Described spacing collar 8 outer rim is respectively equipped with centered by valve rod 5 and makes symmetrically arranged spacing fan platform 84, fan-shaped scarce 82 it are respectively equipped with between adjacent spacing fan platform, and two sectors lack and are also symmetrical arranged centered by valve rod 5, each sector lacks the two ends of 82 and is equipped with spacing end face 83, the rotation angle that between the spacing end face 83 at scarce 82 two ends of each sector, structure is in 90 °.
One of them spacing fan platform 84 of described spacing collar 8 is provided with hole 81, location, this hole, location is just on same diameter line with the lockhole 34 at valve body 3 top, therefore when spacing collar 8 with valve rod 5 turn to location hole 81 be positioned at directly over the lockhole 34 of installation base 31 time, locking magnetic piece 12 in lockhole will stretch out lockhole 34 and enter in hole 81, location, then valve is in the spacing state of locking, namely cannot freely rotatable valve opening and closing；When spacing collar 8 depart from locking states and rotate with valve rod 5 and when making valve be in switchable state, namely spacing collar 8 rotates with valve rod 5 and rotates, then the spacing magnetic piece 11 in two spacing holes 33 is respectively protruding into two sectors and lacks in 82, and the rotating switch lacking interior spacing end face 83 structure in 90 ° by each sector is spacing.
Described handle 7 top is provided with the unlatching handwheel 9 making positioning assembling respectively through single flat department axle 72 and single flat department hole 93, therefore handle 8 rotation can drive unlatching handwheel 9 synchronous axial system, described unlatching handwheel is in the form of annular discs, opening, handwheel 9 is provided with three open holes 92 corresponding with two spacing holes 33 on installation base, lockhole 34 position respectively, being equipped with hard-wired unlatching magnetic piece 91 in three open holes, the magnetic of this unlatching magnetic piece and spacing magnetic piece 11, locking magnetic piece 12 is repelled each other.
As shown in Figure 1, shown in Figure 5, when valve normally uses, spacing magnetic piece 11 stretches out spacing hole 33 under the elastic force effect of limit spring 10 and exposes, and the sector stretching into spacing collar 8 lacks in 82 simultaneously, then handle 7 rotates with ovable valve stem 2 and the ball valve core 1 being fitted on valve rod, spacing collar 8 synchronous axial system, then lack two of 82 by fan-shaped to make valve switch in 90 ° of spacing end faces 83 rotating angles be 90 ° of rotary spacings, thus avoiding conventional ball valve unrestricted defect that cannot accurately control keying situation when opening and closing operation.
Such as Fig. 3, shown in Fig. 6, when valve needs restriction to use, open handwheel 9 and be set on handle 8, open on handwheel 9 open magnetic piece 91 by the spacing magnetic piece 11 of opposing magnetic force pushing tow overcome limit spring 10 elastic force and from sector lack 82 depart from and in be reduced in spacing hole 33, then handle 7 with ovable valve stem 5 and spacing collar 8 counterclockwise to time directly over the lockhole 34 in hole 81, the location overlap on spacing collar to installation base 31, take off unlatching handwheel 9, locking magnetic piece 12 in lockhole 34 is stretched out lockhole 34 by locking spring push and enters in hole 81, location, now valve is in locking states, handle cannot rotate, valve cannot open and close.
When valve cancels restriction use, need to be set on handle 7 by opening handwheel 9, by opening magnetic piece 91 by spacing magnetic piece 11 and locking magnetic piece 12 respectively through being reduced in spacing hole 33 in opposing magnetic force pushing tow and in lockhole 34, then handle 7 band ovable valve stem 5 and spacing collar 8 rotationally clockwise to spacing hole 33 be again in fan-shaped lacking below 82 time, take off unlatching handwheel 9, then the spacing magnetic piece 11 in spacing hole 33 stretches into again fan-shaped lacking in 82, and namely valve can be at can 90 ° of limit switch state.
Simultaneously, this utility model needs to use in time changing valve lock closed state to be opened except handwheel 9, when being in locking states and switchable state at valve, all open handwheel 9 without using, also better prevent from opening handwheel 9 to lose or destroyed, thus greatly facilitating valve to be in the use of user during on off state.
The above is only better embodiment of the present utility model, therefore all equivalences done according to the structure described in this utility model patent claim, feature and principle change or modify, and are all included in this utility model patent claim.
