Abstract
The utility model relates to a deviation-adjusting anti-leak wellhead protector, belonging to an associated component of an oil extractor in an oil field. Ball-type packing boxes and a main ball seat are in rotatable connection; a spheric adjusting pressure cap is threaded to the main ball seat; sealing rubber blocks are disposed between the main ball seat and the ball-type packing boxes; a spray-preventing ball is located in a pressure cap in the middle of the main ball seat; a spring is arranged between the spray-preventing ball and the pressure cap; O-shaped rings are arranged on end parts of the pressure cap and the main ball seat; packings are arranged in the ball-type packing boxes; packing pressure caps are pressed on the packings; and top packing box pressure caps are threaded to the ball-type packing boxes. The deviation-adjusting anti-leak wellhead protector is novel in structure, uniform in bearing, environment-friendly and energy-saving, increases production, has no eccentric wear or leakage, and can prolong service life of a rubber packing and increase working efficiency.
Description
Technical field
The utility model belongs to the oil-field oil pumper associated components, refers in particular to a kind of well head tuningout anti-leak tree protector that is used for.
Background technology
During oil producing operation, well head sealing and eccentric wear directly affect the working efficiency of oil recovery, the installation of the oil pumping unit base that has is difficult to realize fully overlapping of polished rod axis and well head axis, cause oil pumper polished rod in operation process to produce lateral shift, polished rod and well head are not point-blank, impel well head packing eccentric wear to cause leakage of oil, gas, contaminated environment, the output that reduces.The fixed conventional type wellhead polish rod sealing device that use in present some oil field, actually being exactly one is tied and can not dissolves the fulcrum that laterally moves, cause that encapsulant is one-sided to cause crude oil leakage being subjected to sizable side-friction, need frequently compress and change packing.Oil pumper inefficiency, workload are strengthened.
Summary of the invention
The utility model provides a kind of tuningout anti-leak tree protector, to solve the oil pumping lubricating oil leakage, need frequently compress and change packing, the problem that inefficiency, workload are strengthened.
The technical scheme that the utility model is taked is: ball-type packing box and main body ball seat are rotationally connected, spheroid is adjusted pressure cap and is threaded with the main body ball seat, between spheroid ball seat and the ball-type packing box caulking gum piece is arranged, spray-proof ball is arranged in main body middle part pressure cap, between spray-proof ball and pressure cap spring is arranged, there is O type circle pressure cap and main body ball seat end, in the ball-type packing box packing are arranged, the packing pressure cap is pressed on the packing, and last packing box pressure cap is threaded with the ball-type packing box.
Advantage of the present utility model is: novel structure, have that stressed evenly eccentric wear does not leak, and the characteristics of free from environmental pollution and Increasing Production and Energy Saving can prolong the rubber packing and double to increase the service life, and have improved operating efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Ball-type packing box 6 is rotationally connected with main body ball seat 4, spheroid is adjusted pressure cap 7 and is threaded with main body ball seat 4, between spheroid ball seat 4 and the ball-type packing box 6 caulking gum piece 5 is arranged, spray-proof ball 2 is arranged in main body middle part pressure cap 11,11 of spray-proof ball 2 and pressure caps have spring 1, and there is O type circle 3 pressure cap and main body ball seat 4 ends, and packing 8 is arranged in the ball-type packing box 6, packing pressure cap 9 is pressed on the packing 8, and last packing box pressure cap 10 is threaded with ball-type packing box 6.
Working method of the present utility model is: the main body ball seat is threaded with the wax removal valve, polished rod is passed from the centre, the ball-type packing box can vertically rotate by 360 degree at random automatically, also can move the direction finding central point by 360 degree tuningouts, make packing box and polished rod point-blank, prevent well head packing eccentric wear, fracture, the blowout prevention effect in the packing box blowout-proof pressure cap as polished rod.
