Described flat key lower end is connected with locating column, and spring housing is located on locating column.
Described flush end Cock screw is counterbore anti-theft screw.
Described magnet is cylindric permanent magnet.
Described valve gap is provided with groove, and Anti-theft cap lower end is arranged in groove.
Described stuffing box gland comprises the first stuffing box gland and the second stuffing box gland, and the first stuffing box gland is pressed on positioning table, and the second stuffing box gland is arranged on the first stuffing box gland top.
In the utility model, magnet, spring, flat key and valve rod form burglar-proof mechanism, only have when moving up and down by the handwheel promotion magnet of coupling, just can realize the rotation of valve rod, its anti-theft effect is better, and general personnel cannot open, and professional workforce is easy to open and close.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is cross-sectional schematic of the present utility model.
1. valve gap, 2. valve rod, 3. groove, 4. Anti-theft cap, 5. the first stuffing box gland, 6. the second stuffing box gland, 7. positioning table, 8. locating column, 9. flush end Cock screw, 10. spring, 11. slip pearls, 12. flat keys, 13. magnets.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of magnetic anti-theft gate valve, comprise valve body, valve gap 1 and valve rod 2, between valve rod 2 and valve gap 1, be provided with stuffing box gland, valve rod 2 is provided with positioning table 7, positioning table 7 is arranged in the locating slot of valve gap 1, in the center hole of valve rod 2, be provided with spring 10, spring 10 tops are provided with flat key 12, flat key 12 tops are provided with magnet 13, magnet 13 and valve rod 2 upper ends are covered with Anti-theft cap 4, are provided with flush end Cock screw 9 in the bolt hole of Anti-theft cap 4, and flush end Cock screw 9 is pressed on slip pearl 11 in the groove of valve rod 2 sidewalls.Described slip pearl 11 is steel ball.Described Anti-theft cap 4 tops are multicolumn shape, or other nonstandard shapes, and ordinary person cannot turn Anti-theft cap by instruments such as conventional spanners like this.
The utility model use principle is as follows: when use, need to there be handwheel or the spanner of cooperation, the form fit of the cavity geometry of handwheel and Anti-theft cap 4, when use, handwheel sleeve is located on Anti-theft cap 4, just can realize the rotation of Anti-theft cap 4, simultaneously, the below of handwheel is also provided with permanent magnet, the magnetic direction of this permanent magnet is contrary with magnet 13, in the time handwheel being placed on Anti-theft cap 4, magnet 13 is subject to downward repulsive force, magnet 13 drives flat key 12 to move downward, at this moment rotate handwheel, Anti-theft cap 4 and valve rod 2 link, valve rod 2 is in the process of rotating, open amount that can regulation gate valve.After adjusting is complete, handwheel is removed, now under the restoring force effect of spring 10, flat key 12 moves up, and flat key 12 enters in the cavity of Anti-theft cap 4 completely, and now flat key 12 and valve rod 2 depart from, even if rotate Anti-theft cap 4, valve rod 2 still cannot rotate, and Anti-theft cap 4 is in idling conditions, keying that cannot regulation gate valve.
