Description
Technical field
The utility model provides a kind of oil well to regulate polished rod sealer automatically, is specially adapted to all kinds of producing wells of reciprocating type suction.
Background technology
In the oil recovery process of current oil field, the polished rod sealer of pumpingh well well head is made up of packing and packing box mostly, polished rod and top packing box seal during use, polished rod pumps, polished rod and packing friction, wearing and tearing along with packing, especially when oil pumper and well head centering are bad, polished rod and packing eccentric wear, packing loses sealing function soon, therefore necessary frequent fastening packing box or replacing packing, increased the oil recovery working strength of workers, reduced the application life of sealed packing, usually because packing box is fastening untimely, produce and run, emit, drip, leak phenomenon, cause environment pollution easily.
Summary of the invention
The purpose of this utility model provides a kind of new type of rod sealing unit, is specially adapted to all kinds of producing wells of reciprocating type suction, can effectively improve the application life that prolongs sealed packing, prevents the generation of oil leakage phenomenon and environment pollution.
A kind of oil well of the utility model is regulated polished rod sealer automatically, and it comprises lower house, lower ball base, bulb, upper ball base, gland, one-level packing, blowout prevention section, secondary packing, secondary packing box, pressure ring; Wherein, lower ball base, bulb, upper ball base are slidably mounted in the lower house, and bulb is stuck in the space of upper ball base and lower ball base composition; Gland is fixed on the lower house upper outside, and compresses ball seat; The one-level packing is coaxial to be installed in the bulb; The blowout prevention section is installed on the bulb, and the secondary packing box is installed on the blowout prevention section; The secondary packing is installed, the coaxial secondary packing top that is arranged at of pressure ring in the secondary packing box.
The spring of wear extent compensating action wherein, has been installed in the described secondary packing box.
Wherein, described secondary packing box upper outside is provided with the flap valve that prevents that crude oil leaks behind the disconnected bar.
A kind of oil well of the utility model is regulated polished rod sealer automatically, and its advantage and effect are: be specially adapted to all kinds of producing wells of reciprocating type suction, can effectively improve the application life that prolongs sealed packing, prevent the generation of oil leakage phenomenon and environment pollution.

The specific embodiment
Below in conjunction with accompanying drawing the new technical scheme of this practicality is described in detail.
Referring to Fig. 1, the utility model oil well is regulated polished rod sealer automatically, comprises lower house 1, lower ball base 2, bulb 5, upper ball base 3, gland 4, one-level packing 6, blowout prevention section 7, secondary packing 9, secondary packing box 10, pressure ring 11, flap valve 12 etc.; Wherein, lower ball base 2, bulb 5, upper ball base 3 are slidably mounted in the lower house 1, and bulb 5 is stuck in the space of upper ball base 3 and lower ball base 2 compositions; Gland 4 is fixed on the lower house upper outside, and compresses ball seat 3; When polished rod and well head misaligned, lower ball base 2, bulb 5, upper ball base 3 can make polished rod be in the packing center all the time with polished rod horizontal sliding in lower house 1, reduced the packing eccentric wear, improved the packing life-span; The one-level packing is coaxial to be installed in the bulb; Blowout prevention section 7 is installed on the bulb 5, and secondary packing box 10 is installed on the blowout prevention section 7; Spring 8, secondary packing 9 are installed, pressure ring 11 coaxial secondary packing 9 tops that are arranged in the secondary packing box 10; Spring 8 elongations and compression secondary packing 9 make secondary packing 9 carry out wear-compensating when secondary packing 9 is worn; Flap valve 12 is contained in secondary packing box 10 upper outside, and when polished rod is disconnected when taking off, the valve ball 13 of this flap valve ejects to flap valve 12 centers, and sealing flap valve 12 prevents the generation that crude oil leaks.
