Abstract
The utility model relates to a theftproof plug for pipeline comprises body and the cylindricality nut that has the external screw thread, and it has the type of calligraphy cavity to open on the body, and the cylindricality nut vertically and transversely respectively opens porosely, and vertical downthehole key that is equipped with dials the post, horizontal downthehole spring that is equipped with, the both sides of spring are equipped with the spring bolt. The two lock tongues extend out of the nut under the action of the spring, are clamped on the inner step of the convex cavity on the plug body and are shifted by a key, so that the lock tongues can be retracted into the transverse holes of the cylindrical nut. Because the screw cap can be retracted into the pipeline, the screw cap can not be extended out of the pipeline opening without a key, and the anti-theft performance of the plug is improved.
Description
The utility model relates to the screws valve for preventing illagel application that uses on a kind of pipeline, belongs to the device of blocking pipe outlet.
The plug that on existing pipeline, uses, plug body and nut are one, be installed on the pipe outlet after, nut is exposed to outside the mouth of pipe, other people use spanner or other instruments, are easy to plug is laid down.At present, in the outlet of the blow-off line of oilfield, what generally use is exactly this plug, and annual plug is unloaded, and causes number stolen with hundred tons crude oil.
The purpose of this utility model is in order to overcome after plug is installed on the pipeline opening in the prior art, and nut is exposed to outside the mouth of pipe, and the defective that plug is disassembled easily designs a kind of screws valve for preventing illagel application with lock.
The purpose of this utility model is achieved in that it by having externally threaded body and the cylindricality nut is formed, has the chamber of " protruding " font, in this chamber can be installed in the cylindricality nut on the body of plug; Respectively have a hole on the vertical and horizontal of cylindricality nut, two holes intersect " " shape, vertically in the hole key reversed column is being installed, one spring is installed in transverse holes, the both sides of spring respectively are equipped with a dead bolt, two dead bolts stretch out outside the nut under the effect of spring, and be stuck on the interior step of " protruding " font chamber on the plug body, nut is locked in the plug body " protruding " in the font chamber, if need unload plug, only need to stir key reversed column on the nut, in the nut of dead bolt can being withdrawn with key, make nut protruded tube road junction, just plug can be dismantled with spanner or other instrument.
But advantage of the present utility model is just can not make nut protruded tube road junction without key within the nut retraction pipeline opening, has improved the theftproof performance of plug.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1--pipeline opening, 2--plug body, 3--dead bolt, 4--cylindricality nut, 5--key reversed column, 6--spring, 7--spring.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is formed by having externally threaded body 2 and nut 4, has the chamber of " protruding " font on the body 2 of plug, and this chamber can be installed in cylindricality nut 4 in the body 2; On the vertical and horizontal of cylindricality nut 4, respectively have a hole, two holes intersect " " font, vertically in the hole key reversed column 5 is being installed, one spring 6 is installed in transverse holes, a dead bolt 3 is respectively installed in the both sides of spring 6, two dead bolts 3 stretch out nut 4 under the effect of spring 6 basis is external, and is stuck on the interior step of " protruding " font chamber on the plug body 2, simultaneously nut 4 is locked in " protruding " font chamber of plug body 2.The shape of cylindricality nut (4) matches with the shaped upper part of " protruding " font chamber of plug body 2, can be hexagon or tetragonal cylinder, between the bottom of " protruding " the font cavity bottom of plug body 2 and cylindricality nut 4, spring 7 is installed in addition, after dead bolt 3 being opened with key, cylindricality nut 4 is protruded tube road junction automatically just, and then, plug can be dismantled with spanner or other instrument.
Claims (2)
1, screws valve for preventing illagel application, it is formed by having externally threaded body and nut, it is characterized in that having on the body (2) of plug the chamber of " protruding " font, the shaped upper part of this chamber matches with the shape of cylindricality nut (4), can be hexagon or quadrangle, it can be installed in cylindricality nut (4) in the body (2); Respectively have a hole on the vertical and horizontal of cylindricality nut (4), two holes intersect " " shape, vertically in the hole key reversed column (5) being installed, a spring (6) are installed in transverse holes, and the both sides of spring (6) respectively are provided with dead bolt (3).
