Abstract
The utility model discloses a polish rod sealing device for oil pumping well head, which is fit for pumping unit production well. The device comprises a rubber sluice gate, a body and a sealing mechanism. The sealing mechanism comprises an external press hat, a press sleeve, a packing set and a packing stand. The packing set is arranged on the lower part of the packing stand of the sealing mechanism. A diversion joint is arranged on the lower body of the rubber sluice gate. The utility model has secondary sealing function, thus avoiding crude oil leaking when an old packing is replaced by a new one. Because the packing stand structure is changed, the device also has bias-adjusting function, and can protect the environment, reduce pollution and decrease human labor intensity.
Description
Technical field
The utility model relates to petroleum industry petroleum production engineering wellhead equipment, and particularly a kind of production wellhead polish rod seal device is applicable to the pumping production well.
Background technology
In the exploitation of oil-gas field process, adopt oil pumper to drive the sucker rod pumping device mostly, wherein the used oil well polish rod seal device of Jue Daduoshuo sucker rod pumping oil well is the plain edition polished rod sealer, promptly conventional fixed rubber gate.In the production and management process of oil well, the plain edition polished rod sealer has exposed many problems, and during such as well head and oil pumper disalignment, the polished rod eccentric wear seriously causes seal failure, and packing is short application life, and crude oil runs and leaks contaminated environment; The often tight packing of operator stops well and changes packing, and labor strength increases, problems such as cost of production rising.Oil well production efficient is reduced greatly, influence crude output.Therefore the on-the-spot a kind of novel polish rod seal device of design that needs overcomes existing defective.
Summary of the invention
The purpose of this utility model provides a kind of production wellhead polish rod seal device, overcomes the defective of existing polish rod seal device, improves its sealing performance.Avoid the problem that the crude oil race is leaked when changing packing, and make it simplify the well head flow process, thereby reduce production costs and working strength of workers.
The present technique solution can reach above-mentioned purpose: a kind of production wellhead polish rod seal device, comprise rubber gate, main body and sealing mechanism, sealing mechanism has outer pressure cap, gland, goes up packing and packing seat, packing down is set below the packing seat of sealing mechanism, on the main body of rubber gate below, the water conservancy diversion joint is set.
Use the utlity model has following advantage:
1, this device has the secondary seal function, because packing down is set below its packing seat, has improved sealing performance, has avoided the problem that the crude oil race is leaked when changing packing.Change the structure of packing seat, had the oblique function of accent.Protect environment, reduced pollution, reduced cost of production.
2, below the rubber gate, increase the water conservancy diversion joint, saved clip head and well head threeway, reduced the production wellhead parts, reduced the height of well head, guaranteed the sealing of well head.
3, owing to reduced the height of well head, make that the distance between polished rod eye and the well head increases, the workman's that more helps recovering the oil operation has alleviated working strength of workers.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: main body 1, piston 2, adjusting rod 3, sealing ring 4,7 and 8, adjust nut 5, regulating sleeve 6, guider screw 9, following packing 10, lower pressing cap 11, unloading ring 12, packing seat 13, go up packing 14, gland 15, trip bolt 16, outer pressure cap 17, packing pad 18
The specific embodiment
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing, a kind of production wellhead polish rod seal device, comprise rubber gate, main body 1 and sealing mechanism, sealing mechanism has outer pressure cap 17, gland 15, goes up packing 14 and packing seat 13, is packing pad 18 below the last packing 14.Packing 10 down is set below the packing seat 13 of sealing mechanism, on the main body 1 of rubber gate below, the water conservancy diversion joint is set.Packing seat 13 is connected with unloading ring 12, and being connected by lower pressing cap 11 realizations and main body 1.The rubber gate comprises piston 2, adjusting rod 3, sealing ring 4,7 and 8, adjusts nut 5, regulating sleeve 6 and guider screw 9, and is identical with the plain edition polished rod sealer.The utility model is installed on the well head upper flange, well liquid can be directly water conservancy diversion joint on the main body 1 advance the well head flow process, water conservancy diversion joint pipe end cylindrical has screw thread to link to each other with well head gate valve flow process to realize the output of crude oil.Packing seat 13 bottom cylindricals structure spherical in shape, main body 1 top of Pei Heing is circle in the hemispherical with it, and this structure can rise and transfer tiltedly, the function of anti-eccentric wear.The outer pressure cap 17 of sealing mechanism is in radially being provided with screw hole, in load solid screw 16.When changing packing, by adjusting the position that trip bolt 16 reaches fixing outer pressure cap 17 and polished rod.
