Description
The utility model relates to a kind of anti-theft device that oilfield uses, and belongs to the antitheft packing box on the production tree.
Packing box is the visual plant on the production tree.In recent years, the lawless person steals the crude oil phenomenon and is on the rise, and one of means are exactly the Polish rod packing that unclamps on the production tree.Because the packing box that generally use in the oil field is adjusted on the cap two handles are arranged, adjust several circles of cap pine as long as pull hadle, will make packing loosening, under the oil pumper pumping action, substantial oil sprays along polished rod, flows to ground, reaches the purpose of stealing crude oil.This process only needs a few minutes, and the oil recovery workman is extremely difficult to be taken precautions against.Substantial oil is stolen, and national wealth is sustained a loss; Crude oil flows on production tree and the well site simultaneously, has polluted equipment and environment, increases oil recovery workman's workload, has seriously disturbed field produces.
The purpose of this utility model is to avoid the deficiency of above-mentioned technology, and a kind of antitheft packing box that can't become flexible packing is provided.
The purpose of this utility model can reach by the following technical programs: this antitheft packing box is to constitute on the basis of production tree packing pressure cap, form by adjusting pressure cap, packing pressure cap and bulb, it is characterized in that: the internal thread hole that adjustment pressure cap sidewall is fixed a reeded helmet and helmet aligns mutually with the hole that adjustment pressure cap sidewall has; Packing pressure cap external screw thread is fixed with and is adjusted pressure cap behind recessed the bulb and screws bulb and cover the packing pressure cap.
Above-mentioned helmet is symmetrically distributed in the both sides of adjusting pressure cap; The bulb wall is symmetrically distributed with four recessed.
The utility model has following advantage than above-mentioned prior art: owing at the adjustment pressure cap sidewall of this packing box the groove helmet is housed, make special bolt fix bulb, the lawless person is not when having the special bolt spanner, can't become flexible packing, thereby make the lawless person steal crude oil from packing, practical.
Accompanying drawing 1 is that structure of the present utility model is cutd open figure;
Accompanying drawing 2 is A-A sectional views of Fig. 1.
Below in conjunction with accompanying drawing the utility model is further described:
1-in the accompanying drawing adjusts pressure cap; 2-packing pressure cap; The 3-helmet; The 4-bolt; The 5-bulb; Recessed of 6-.
As Fig. 1 in conjunction with shown in Figure 2, this antitheft packing box is to constitute on the basis of production tree packing pressure cap 2, form by adjusting pressure cap 1, packing pressure cap 2 and bulb 5, adjust pressure cap 1 sidewall symmetry and fix 2 helmets 3, helmet 3 has a groove, and purpose is conventional instrument swivel bolt for the lawless person can't use; And helmet 3 has a female hole, cooperates anti-theft bolt 4, and this hole aligns mutually with the hole that adjustment pressure cap 1 sidewall has; Packing pressure cap 2 external screw threads are bulb 5 fixedly, and bulb 5 outer walls have 4 recessed 6 of symmetry, and purpose makes anti-theft bolt 4 withstand recessed 6 from the hole precession of helmet 3.If the special tool that does not match with anti-theft bolt 4 then can't become flexible anti-theft bolt 4, thereby stopped the oil field lawless person steals crude oil from packing problem.Adjust pressure cap 1 and screw bulb 5, make recessed 6 head end that aligns anti-theft bolt 4 of bulb 5, make it firmly, and packing pressure cap 2 is adjusted pressure cap 1 and covers.When needing repairing or change packing, only need to use the special tool loose bolts 4 supporting with anti-theft bolt 4, make bolt 4 leave recessed 6, opposite spin is adjusted pressure cap 1 and pressure cap 1 is unloaded along the external screw thread of bulb 5 get final product then.
