Abstract
The utility model discloses an anti-theft valve. The anti-theft valve comprises a valve body, wherein the valve body comprises a valve nut and a screw rod which is in threaded connection with the valve nut and used to open and close the valve; the valve body has the upper end provided with a rotating device used to rotate the screw rod, the rotating device comprises a cylindrical wheel and a spanner used to rotate the cylindrical wheel, the spanner comprises a handle and a sleeve; the cylindrical wheel is fixedly connected with the upper end of the screw rod and is provided with an eccentric ring groove, the cross sectional shape of which is U-shaped, the ring groove is smoothly transitioned from the widest part to the narrowest part; and the sleeve is matched with the ring groove in structure. The anti-theft valve of the utility model has the advantages of simple manufacturing technique, low cost, convenient and reliable use and good anti-theft performance; so the anti-theft valve is widely applied to various outdoor pipes and can ensure the normal production and pipe transportation.
Description
Technical field
The utility model relates to a kind of valve, and particularly a kind of valve for guarding against theft belongs to valve switch control field.
Background technique
At present, the on-the-spot valve that uses in oil field does not mostly possess antitheft effect, therefore usually stolen oil is stolen gas, the normal production order in oil supply district causes confusion, though some valve takes some measures, for example valve handle and pipeline is pinned with chain lock, but anti-theft effect is bad, mainly be that lockhole is easily dead by plug, causes valve to open because chain lock is easily cut (pounding) to break.The mode that employing casing sealing that also has or cipher lock are hidden is carried out antitheft, these are several to have played antitheft effect to a certain extent, but inconvenient operation, also destroyed easily, and handwheel removably connects with valve, often cause valve not open and close, make it can not guarantee to produce normal operation with line transportation because of handwheel stolen.
Summary of the invention
The object of the invention is exactly the easy robber's defective that overcomes existing valve, provides a kind of and can prevent stolen, as to guarantee production and the normal operation of line transportation valve for guarding against theft effectively.
For achieving the above object, the technological scheme that the utility model adopted is:
A kind of valve for guarding against theft, comprise valve body, described valve body comprises valve nut and the leading screw that is used for opening/shutting valve that is connected with the valve nut thread, it is characterized in that: the upper end of described valve body is provided with and is used for the slewing gear of rotational lead screw, the spanner that described slewing gear comprises cylindrical wheel body and is used for making cylindrical wheel body to rotate, described spanner comprises handle and sleeve, described cylindrical wheel body is fixedlyed connected with the upper end of leading screw, described cylindrical wheel body is provided with eccentric annular groove, the sectional shape of described annular groove is a U-shaped, to the narrowest rounding off, the structure of described sleeve and the structure of annular groove are complementary described annular groove from the widest position.
Below be further improvement to technique scheme:
The arranged outside of described cylindrical wheel body has the protecting jacket of annular, and the lower end of described protecting jacket body is provided with end face, and described end face is provided with through hole, and the upper end of described leading screw is passed through hole and fixedlyed connected with cylindrical wheel body.
Beneficial effect
The utility model adopts said structure; replaced with the handwheel on the early gate with cylindrical wheel body; on the cylindrical wheel body of valve, be provided with eccentric annular groove; make general extracting tool to be applied to it; can only could be under the special spanner effect supporting by degree of tightness with it; therefore has reliable theft protection; the arranged outside of described cylindrical wheel body has the protecting jacket of annular; prevented that also it from unclamping it by spanner or other destructive instrument from the outside or destroy; thereby improved the theftproof performance of valve; production technology of the present utility model is simple; cost is low; easy to use; reliably; have theftproof performance preferably, can be used in a large number be installed in open-air various pipes, guaranteed the normal operation of production and line transportation.
The utility model is described in further detail below in conjunction with drawings and Examples.
