Abstract
The utility model discloses an antitheft gate threaded spindle protector which is composed of a threaded spindle protective sleeve, an antitheft jackscrew and a gate threaded spindle and is characterized in that the threaded spindle protective sleeve takes a shape of cylinder, the surrounding side of the bottom of the cylinder is provided with a reverse female thread, the reserve female thread is provided with the antitheft jackscrew which is vertical to the reserve female thread, the head of the antitheft jackscrew sinks into a concave hole which is arranged at a position corresponding to the threaded spindle protective sleeve as well as a dedicated opener. The utility model not only prevent the threaded spindle protective sleeve from being stolen but also avoids the problems of the gate is not closed and oil stolen caused by flow guiding and pressure building. The utility model has the advantages of simple structure and convenient use, maintains the normal production of oil fields and prevents serious accidents from happening.
Description
One, technical field
The utility model relates to the anti-theft gate leading screw protector of using in a kind of oil gas water gathering and transportation technology flow process.
Two, background technique
At present great majority all are the rise-fall type gate valves of usefulness in the oilfield water gathering and transportation technology, and the characteristics of these valves are that to open in application be to reach the end, the pass be complete shut-down on earth, do not allow half-open half pass, otherwise flashboard can come off.The valve of standard-sized sheet like this is outside leading screw is exposed to throughout the year, through the precipitation etch of exposing to the weather; the meeting corrosion, when really needing the water conservancy diversion journey, motionless with regard to switch; especially because of collecting defeated problem water conservancy diversion journey being arranged, all is anxious, in case the water conservancy diversion journey is slow; can cause serious accident, for this reason, the oil worker smears a little butter on leading screw; put casing protection, but casing puts soon, just stolen smoothly by the lawless person; butter has also been washed off by strong wind and heavy rain, loses protective action.Lawless person's oil and gas larceny also is to commit theft from gate in addition, and often the gate of frequent switch will prevent that also the lawless person from closing upper lock gate and building the pressure and commit theft, and need both protect the gate leading screw will prevent that also the lawless person from committing theft.
Three, summary of the invention
The purpose of this utility model provides a kind of anti-theft gate leading screw protector, solves the problem that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of leading screw sheath, antitheft jackscrew and gate leading screw, it is characterized in that the leading screw sheath is a drum shape, all sides are provided with the reverse box thread that cooperates with the leading screw male thread in the drum bottom, be provided with the vertical oppositely antitheft jackscrew of box thread at reverse box thread place, in the corresponding set shrinkage pool of the recessed leading screw sheath of antitheft jackscrew head, antitheft jackscrew is furnished with the special opening instrument.
Diameter more than the reverse box thread of leading screw sheath is greater than the diameter of leading screw.
The utility model had both solved the leading screw sheath and had not gone adrift, and had solved gate again and had not been shut the water conservancy diversion journey or build the pressure the problem of oil steathily.Simple in structure, easy to use, safeguarded the ordinary production in oil field, prevented the generation of serious accident.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
The antitheft jackscrew 3-of 1-leading screw sheath 2-gate leading screw among the figure
Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of leading screw sheath 1, antitheft jackscrew 2 and gate leading screw 3, leading screw sheath 1 is a drum shape, all sides are provided with the reverse box thread that cooperates with the leading screw male thread in the drum bottom, be provided with at reverse box thread place perpendicular to the reverse antitheft jackscrew 2 of box thread, in the corresponding set shrinkage pool of the recessed leading screw sheath of antitheft jackscrew head, antitheft jackscrew is furnished with the special opening instrument.When using the utility model, earlier will spread butter on the gate leading screw 3, again leading screw sheath 1 is enclosed within on the gate leading screw 3, oppositely twist the leading screw sheath, be screwed to the end, antitheft jackscrew 2 is screwed on, hold out against the gate leading screw and get final product, the lawless person thinks leading screw sheath or pass gate water conservancy diversion journey or the oil steathily that builds the pressure steathily, does not have antitheft jackscrew special opening instrument and the structure of not making clear in the leading screw sheath to accomplish.
Claims (2)
