It is fixedly connected in bar nut 13.Wherein for the length of bar 12, it can be determined according to practical valve situation, generally may be used
So that the length of bar 12 is slightly longer than valve length is advisable.
Valve anti-open device provided by the embodiment of the utility model includes fixation kit 1 and locked assembly 2, structure letter
It is single, can self manufacture so as to save the cost solve the problems, such as that valve for guarding against theft is at high cost；In addition, passing through setting bar nut
13 connect bar 12 in cabinet, so that common spanner cannot be used for the fastening and disassembly of bar nut 13, need using dedicated
Wrench socket is operated, and the versatility of accessory is thus avoided, and makes external staff that can not open valve, or increases opening valve
The difficulty of door, avoids crude oil from losing, it is ensured that oil well normally produces to the greatest extent.
In the prior art, also carried out frequently with the mode for being welded valve export plug antitheft, but external staff is generally
Weld seam, and forged scene can be destroyed, makes to be not easy to be found when employee Cha Jing.And apply valve provided by the embodiment of the utility model
Anti-open device, if scene is not easy to pretend by strong destruction, employee can have found and deal in time in patrol.
In above-mentioned valve anti-open device, for the ease of fixation of the fixation kit 1 on valve handle, such as Fig. 1 institute
Show, the first locating slot 1101 can be provided on top plate 11, and the first locating slot 1101 is adapted with the handwheel outer profile of valve；
First locating slot 1101 and bar 12 are ipsilateral, and bar 12 is located at the inside of the first locating slot 1101.
In application, the bar 12 of fixation kit 1 to be each passed through to the gap of valve handle, the handwheel of valve can be made to be located at the
In a positioning groove 1101, consequently facilitating fixation kit 1 is fixed on handwheel.Meanwhile first locating slot 1101 cell wall also opponent
Wheel plays a protective role, and avoids the rotation of valve handle.
Further, as shown in Figure 1, the second locating slot 1102 can also be arranged on top plate 11, the second locating slot 1102 with
Fixture nut in the middle part of the handwheel of valve is adapted；
Second locating slot 1102 and bar 12 are ipsilateral, and the second locating slot 1102 is between at least two bars 12.
In application, the bar 12 of fixation kit 1 to be each passed through to the gap of valve handle, it is fixed that the handwheel of valve is located at first
In the slot 1101 of position, meanwhile, the cell wall of the second locating slot 1102 blocks the fixture nut in the middle part of the handwheel of valve, thus can realize pair
Valve handle further fixes.
Similarly, the fixation for the ease of locked assembly 2 on valve handle, as shown in figure 3, can also be set on backboard 22
Backboard fixation hole 2202 is set, backboard fixation hole 2202 is adapted with the bottom boss of valve.
In application, the bottom boss of valve can be made to be stuck on backboard fixation hole 2202, so that locked assembly 2 is fixed on valve
On handwheel, it is convenient for subsequent operation.Wherein, backboard fixation hole 2202 can be set to have shape compatible with the bottom boss of valve
Shape, for example, being rectangular.
Furthermore, it is contemplated that security insurance can also be designed further following on the basis of above-mentioned valve anti-open device
Antitheft details.
Since the exterior contour of common fixture nut is hexagon (i.e. " hex nut "), in order to increase opening difficulty,
It can make bar nut 13 that there is unconventional exterior contour, such as make external shape in triangle (triangle nut) or quadrangle (four
Angle nut) or pentagon (pentagon nut) or any other unconventional shape.Correspondingly, operator can be according to bar nut
13 exterior contour designs corresponding wrench socket, and the exterior contour of the inside groove and bar nut 13 that make wrench socket is adapted,
And it can be used to specially opening or tightening bar nut 13.
Further, in order to increase the opening difficulty of chamber door 23, thus the anti-theft effect of stiffening device, as shown in Fig. 2, can
Making locked assembly 2 further includes the first bolt 24；And

End has interior polygonal connected in star, and interior polygonal is triangle, or is quadrangle, or is pentagon.
In application, after closing chamber door 23, the first screw thread of the second threaded hole 2301 and the inside of cabinet on chamber door 23
Hole 2101 is corresponding, then passes through the second threaded hole 2301 using the first bolt 24 and is fixed in the first threaded hole 2101.
Since the second threaded hole 2301 is counterbore, the end of the first bolt 24 will be submerged in counterbore, and needing to use has
First spanner 3 (as shown in Figure 4) of stopper is opened, and the shape of stopper will be with the groove shapes of the end of the first bolt 24
It is adapted.
For example, when the end of the first bolt 24 has interior pentagon, as shown in figure 4, the stopper of the first spanner 3 can be made
Exterior contour is in pentagon.
More specifically, as shown in Fig. 2, can make to be provided with the first convex block towards box house, the first screw thread on coaming plate 21
Hole 2101 is provided on the first convex block；
The second convex block towards the box house is provided on chamber door 23, the second threaded hole 2301 is provided with the second convex block
On.
Similarly, in order to further strengthen the anti-theft effect of device, as shown in Fig. 2, locked assembly 2 can be made to further include second
Bolt 25；And
Cabinet is internally provided with third threaded hole 2102；
The 4th threaded hole 2302 is provided on chamber door 23, the 4th threaded hole 2302 is counterbore；
Second bolt 25 passes through the 4th threaded hole 2302 and is fixed in third threaded hole 2102, and the end of the second bolt 25
Profile is in polygonal, and polygonal is triangle, or is quadrangle, or is pentagon.
In application, after closing chamber door 23, the third screw thread of the 4th threaded hole 2302 and the inside of cabinet on chamber door 23
Hole 2102 is corresponding, then passes through the 4th threaded hole 2302 using the second bolt 25 and is fixed in third threaded hole 2102.
Since the 4th threaded hole 2302 is counterbore, the end of the second bolt 25 will be submerged in counterbore, and needing to use has
Second spanner 4 (as shown in Figure 5) of sleeve is opened, and the inner cylinder shape of sleeve will be with the outside of the end of the second bolt 25
Profile is adapted.
For example, when the end profile of the second bolt 25 is in pentagon, as shown in figure 5, can make in the sleeve of the second spanner 4
Cylinder is in pentagon.
More specifically, as shown in Fig. 2, being provided with the third convex block towards box house, third threaded hole on coaming plate 21
2102 are provided on third convex block；
The 4th convex block towards box house is provided on chamber door 23, the 4th threaded hole 2302 is provided with the 4th convex block
On.
When needing to close valve, after bar nut 13 being fixed, chamber door 23 is closed, by special spanner (example
Such as the first spanner 3) it is fixed on the first bolt 24 in first threaded hole 2101 across the second threaded hole 2301, by special spanner
(such as second spanner 4) is fixed on the second bolt 25 in third threaded hole 2102 across the 4th threaded hole 2302, then utilizes
The fixed locking of chamber door 23 is realized multiple-protection by lockset；When needing to open valve, operator needs first to be opened with key and lock
Tool backs out the first bolt 24 and the second bolt 25 by the first spanner 3 and the second spanner 4 respectively, opens chamber door 23, then using special
Bar nut 13 is unscrewed with wrench socket, removes locked assembly 2, then removes fixation kit 1, handwheel could be operated and opened
It closes.Make external staff that can not open valve as a result, or increase the difficulty for opening valve, avoids crude oil from losing to the greatest extent,
Ensure that oil well normally produces.
The above is merely for convenience of it will be understood by those skilled in the art that the technical solution of the utility model, not to
Limit the utility model.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
