Abstract
An antitheft screw plug for the oil drain hole of a booster pump gearbox is composed of a cylindrical screw plug and a special wrench for detaching the screw plug. The screw plug has an upper part with large diameter and a lower part with small diameter, wherein pin threads are formed on the periphery of the upper part; a cylinder is arranged at the center and is provided with an annular cavity at the periphery; two symmetric crescent grooves are formed on the bottom of the annular cavity; a crisscross-shaped via-hole is formed on the cylinder on the lower part of the screw plug; and a retaining bolt is inserted in the via-hoe. The special wrench has a cylindrical shape with a diameter slightly smaller than the diameter of the annular cavity of the screw plug, wherein a center hole is formed at the center and has a diameter slightly larger than the diameter of the cylinder of the screw plug; wrench edges are arranged on the upper part of the wench; and two symmetric crescent convex edges are formed on the lower part and are matched with the crescent grooves of the screw plug. The antitheft screw plug solves the theft problem of the lubricating oil in the booster pump gearbox, and the screw plug cannot be detached without the special wrench or even by forcedly detachment. The retaining bolt inserted in the crisscross-shaped via-hole at the lower part is retained on a pump body to achieve secondary theft prevention.
Description
One, technical field
The utility model relates to a kind of oil-field flooding suction booster gearbox drain oil screws valve for preventing illagel application.
Two, background technique
At present water injection in low-permeability oilfield needs very high pressure, the pressure of general water injection pump is incompatible, and these low permeability oil fields belong to little fault block character, the well number is few, can not build a cover high pressure water injection system for this reason,, drop into much larger than output because of investment is too big, also can only on individual well, set up supercharging equipment, the plug at the suction booster gearbox drain oil place that uses on the current individual well is non-anti-theft, and the lawless person often dismantles plug and steals lubricant oil, as untimely discovery, will burn out suction booster, influence water filling.
Three, summary of the invention
The purpose of this utility model provides a kind of suction booster gearbox drain oil screws valve for preventing illagel application, solves the stolen problem of suction booster gear-box lubricating oil 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 plug and the special spanner that unloads plug, and it is cylindrical to it is characterized in that plug is made as, and upper diameter is big, and lower diameter is little; Upper periphery is provided with male thread, and the center is made as cylindrical body, and the cylindrical body periphery is made as the annular space chamber, establishes the crescent of two symmetries in bottom surface, annular space chamber; On plug lower cylindrical body, be provided with the cross through hole, be inserted with retaining bolt in the through hole, special spanner is made as cylindrical, diameter is slightly less than the ring lumen diameter of plug, the center is provided with center hole, and center-hole diameter is slightly larger than the cylinder diameter of plug, and special spanner top is provided with the spanner rib, the bottom is provided with two crescent moon fins of symmetry, with the crescent coupling of plug.
The utility model has solved the stolen problem of suction booster gear-box lubricating oil, does not have special spanner to unload to fall plug, has both made to unload that movable wire is stifled to be unloaded yet, and the solid retaining bolt that is inserted with in the cruciform vent of bottom keeps off on the pump housing, plays the antitheft effect of secondary.

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 plug and the special spanner that unloads plug, and it is cylindrical to it is characterized in that plug is made as, and upper diameter is big, and lower diameter is little; Upper periphery is provided with male thread, and the center is made as cylindrical body, and the cylindrical body periphery is made as the annular space chamber, establishes the crescent of two symmetries in bottom surface, annular space chamber; On plug lower cylindrical body, be provided with the cross through hole, be inserted with retaining bolt in the through hole, special spanner is made as cylindrical, diameter is slightly less than the ring lumen diameter of plug, the center is provided with center hole, and center-hole diameter is slightly larger than the cylinder diameter of plug, and special spanner top is provided with the spanner rib, the bottom is provided with two crescent moon fins of symmetry, with the crescent coupling of plug.
When using, the crescent moon fin 6 of special spanner 5 is inserted in the crescent 3 at the bottom of the cylindrical body 2 peripheral annular chambeies of screws valve for preventing illagel application 1, screws valve for preventing illagel application is installed in the drain oil of gearbox, retaining bolt is inserted in the cross bore 4, install pump housing side plate and get final product with spanner.
