Description

The cipher lock valve

One, technical field: the utility model relates to a kind of valve, particularly a kind of valve that has cipher lock.

Two, background technique: the consistent people of being of the antitheft problem of valve pay close attention to and problem anxious to be solved, in recent years, people are around this problem, taked several different methods, summing up to get up mainly is to increase anti-theft device on valve body, and this device need use special instrument to finish, and the thief only need solve special tool, anti-theft device is just ineffective, thereby pipeline, the stolen phenomenon of valve happen occasionally.

Three, summary of the invention: the purpose of this utility model is exactly to be difficult to antitheft problem outside, the cipher lock valve that provides a kind of integrated design to utilize password locking at the naked leakage of opening mechanism in the existing valve anti-theft device.

Its technological scheme is: existing valve comprises valve body 6, spool 7 and valve core link rod 13 compositions.Feature of the present utility model is: valve body 6 upwards is provided with the rectangular projecting platform around valve core link rod 13 external parts, the centre is provided with annular groove, and rotating shaft 15 underparts of cipher lock place in the annular groove and with the protruding bolt grafting of valve core link rod 7 ends and cooperate rotation fixing.Fixedlyed connected with valve body 6 by the bolt 10 that is distributed in periphery by the pin clamp 5 of living in the cipher lock bottom.The housing 2 of cipher lock is " U " shape cuboid, and the centre is equipped with shaft seat 1.Be with several mutually stacked number plates 3 outside shaft seat 1, the number plate 3 after stacked just in time places in " U " shape groove of housing 2, and is fixed in the housing 2 by peripheral bolt 10 by mandrel 4.Number plate 3 internal surfaces are trapezoidal, and outer surface is provided with ten numerals of 0-9.To offering circular groove, rotating shaft 15 is inserted has behind the shaft seats 1 pin 14 that the two is fixed, and simultaneously the mandrel 4 and the pin clamp 5 of living is clipped in wherein in the lower shaft of shaft seat 1.Groove is axially offered in the same side at rotating shaft 15, shaft seat 1, number plate 3 and mandrel 4, axially inserts the pin 9 of living along groove.Insert in the groove prefabricated on the housing 2 pin 9 upper ends of living, and the lower end has the conical surface, with the conical surface groove fit on the pin clamp 5 of living in advance, offers the serrated slot with number plate 3 radial fit in the outside of the pin 9 of living.In live pin 9 tops and groove that housing 2 grafting cooperate, spring 8 is installed.Be provided with protrusion on shaft seat 1 top axis, projection cooperates with circular groove on the housing 2, connects pad 12 and nut 11 at valve core link rod 13 extensions.

The utility model is realized the valve locking by the password combination on the combination disk, and housing and valve body are to synthetic seal during lock state, and fixing bolt is covered by in the body, and appropriator is opened nowhere, has thoroughly solved the antitheft problem of valve.

Four, description of drawings:

Fig. 1 is an overall structure sectional view of the present utility model;

Fig. 2 is the A-A sectional view among Fig. 1.

Five, embodiment:

With reference to accompanying drawing: the valve body 6 at existing valve upwards is provided with the rectangular projecting platform around valve core link rod 13 external parts, and the centre is provided with annular groove, connects pad 12 and nut 11 at valve core link rod 13 extensions.Rotating shaft 15 underparts of cipher lock place in the annular groove and with the protruding bolt grafting of valve core link rod 7 ends and cooperate rotation fixing.The cuboid that cipher lock is made up of housing 2, mandrel 4, pin clamp 5, rotating shaft 15, shaft seat 1, the combination disk 3 of living and the pin 9 of living etc., fixedlyed connected with valve body 6 by the bolt 10 that is distributed in periphery by the pin clamp 5 of living in its underpart.The housing 2 of cipher lock is " U " body, and the centre is equipped with shaft seat 1.Be with 3 mutual stacked number plates 3 outside shaft seat 1, number plate 3 internal surfaces are trapezoidal, and outer surface is carved with ten numerals of 0-9.Number plate 3 after stacked just in time places in " U " shape groove of housing 2, and is fixed in the housing 2 by peripheral bolt 10 by mandrel 4.Be provided with protruding axle at the top of shaft seat 1 and be inserted in the groove that is provided with in the housing 2, lower shaft is to offering circular groove.Rotating shaft 12 bottoms are provided with the convex edge, and it is interior fixing by pin 14 that the circular trough of shaft seat 1 is inserted on top, simultaneously the mandrel 4 and the pin clamp 5 of living are stuck in wherein.Groove is axially offered in the same side at rotating shaft 15, shaft seat 1, number plate 3 and mandrel 4, axially insert the pin 9 of living along groove, insert in the groove prefabricated on the housing 2 pin alive 9 upper ends, in live pin 9 tops and groove that housing 2 grafting cooperate, spring 8 is installed, the lower end has the conical surface, with the pre-conical surface groove fit on the pin clamp 5 of living, offer serrated slot in the outside of the pin 9 of living with number plate 3 radial fit.Note, the number number (as 3,1,8) of one group of correspondence is set on each number plate this moment.After setting is finished, this moment is during roll-shell 2, after the conical surface groove interaction of the conical surface of pin alive 9 bottoms and the pin clamp 5 of living, make the pin 9 of living up along the groove in the combination disk 3, pin 9 bottoms thoroughly break away from the pin clamp 5 of living until living, drive rotating shaft 15 when housing rotates and rotate, rotating shaft 15 drives valve core link rod 13 and rotates, thereby with valve open.Otherwise, after roll-shell 2 drives valve closing, any rotational password dish 3, the relative position number of change combination disk 3 makes the grooves in the combination disk 3 leave position of selling 9 outer openings grooves alive, the opening slot of pin 9 alive is just blocked by the projections in the combination disk 3, this moment roll-shell, the pin 9 of living is axially blocked by combination disk 3, the conical surface groove on the conical surface of pin 9 bottoms of living and the pin clamp 5 of living can not separate, housing 2 can not rotate, and valve also just can not be opened.Because fixing bolt 10 is to be embedded in mandrel 4 and to live pin clamp 5 involutory surfaces, bolt 10 is closed simultaneously behind valve closing, after having only password that correct roll-shell 2 is set, bolt could expose, therefore the valve of this structure is not being known under the situation of password, remove the non-destructive cutting, otherwise can't open, thoroughly solved problem by the valve theft.
