Abstract
An offset adjustment automatic compensation sealer consists of an upper spring, an upper gland bush, an exterior gland bush, an upper sealing element, a seal cavity, a lower gland bush, a lower seal element, a pressing sleeve, a lower spring, an offset adjustment upper joint, an offset adjustment gland bush and an offset adjustment lower joint. When a slipstick reciprocates, the upper sealing element is working; eccentric wear between the slipstick and the sealing elements is prevented by adjusting radial positions of the offset adjustment upper joint and the offset adjustment lower joint. After the upper sealing element or the lower sealing element is worn, compensation can be made automatically under the spring action. When the upper sealing element is to be replaced, the lower sealing element is in sealing state, at this moment, the upper sealing element can be replaced. Workers are not required to turn an element tight for sealing, the labour intensity of workers is reduced. Centers of the sealing elements are superposed with the center of the slipstick by adjusting the radial position of the offset adjustment upper joint and the offset adjustment lower joint to prevent eccentric wear between the slipstick and the sealing elements; the friction between the slipstick and the sealing elements is accordingly reduced. In this way, energy is conserved, and service lives of the sealing elements are increased.
Description
One, technical field:
The utility model is the pumpingh well wellhead assembly that oil exploitation is used, particularly a kind of tuningout automatic compensation sealing device.
Two, background technology:
Existing pumpingh well polished rod sealer kind is more, but all exist certain defective, if any the tuningout ability not enough, require oil recovery workman screwing hermetic at any time, the inconvenience of sealing degree of tightness is grasped, sealing part abrasion is very fast on the one hand, needs often to change seal, and operator's labour intensity is bigger, the friction of seal and polished rod is serious on the other hand, application life is short, has increased the load of oil pumper, and oil machinery efficient is low.
Three, summary of the invention:
The purpose of this utility model provides a kind of tuningout automatic compensation sealing device, has bigger tuningout ability, does not need frequent screwing hermetic, oil well management is convenient, and workload is few, and the frictional force between polished rod and the seal is little, long service life alleviates the oil pumper load, energy conservation.
The purpose of this utility model is achieved in that by upper spring, upper press cover, outer gland, last seal, annular seal space, lower cover, lower seal, gland, lower spring, the tuningout top connection, the tuningout gland, the tuningout lower contact is formed, upper spring, upper press cover is in the outer gland, upper spring is on upper press cover, last seal is installed in the upper port of annular seal space, last seal upper end is a upper press cover, lower cover, lower seal is installed on the lower thread of annular seal space, gland, lower spring is installed in the endoporus of tuningout top connection top, gland is on lower spring, it on the gland lower seal, outer gland bottom connects with annular seal space top, the annular seal space bottom connects with tuningout top connection top, tuningout top connection lower surface contacts with tuningout lower contact upper surface, the circular bead surface of tuningout top connection is pushed down in tuningout gland endoporus bottom surface, and tuningout gland internal thread connects with the external screw thread of tuningout lower contact.
The beneficial effects of the utility model: upper spring, lower spring can play automatic compensating action, and the workman's screwing hermetic at any time that do not need to recover the oil has alleviated working strength of workers.By adjusting the radial position of tuningout top connection, tuningout lower contact, the center of seal is overlapped with the center of polished rod, prevent polished rod and seal eccentric wear, reduced the friction between polished rod and the seal, both can energy conservation, can prolong the application life of potted component again.
Four, description of drawings:
Accompanying drawing is a complete section assembled view of the present utility model.
Five, embodiment:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
As seen from the figure, embodiment of the present utility model is by upper spring 1, upper press cover 2, outer gland 3, last seal 4, annular seal space 5, lower cover 6, lower seal 7, gland 8, lower spring 9, anti-rotation pin 10, tuningout top connection 11, tuningout gland 12, tuningout lower contact 13 is formed, upper spring 1, upper press cover 2 is in the outer gland 3, upper spring 1 is on upper press cover 2, last seal 4 is installed in the upper port of annular seal space 5, last seal 4 upper ends are upper press covers 2, lower cover 6, lower seal 7 is installed on the lower thread of annular seal space 5, gland 8, lower spring 9 is installed in the tuningout top connection 11 top endoporus, gland 8 is on lower spring 9, it on the gland 8 lower seal 7, outer gland 3 bottoms connect with annular seal space 5 tops, annular seal space 5 bottoms connect with tuningout top connection 11 tops, tuningout top connection 11 lower surfaces contact with tuningout lower contact 13 upper surfaces, the circular bead surface of tuningout top connection 11 is pushed down in tuningout gland 12 endoporus bottom surfaces, and tuningout gland 12 internal threads connect with the external screw thread of tuningout lower contact 13.Between annular seal space 5 and the tuningout top connection 11 anti-rotation pin 10 is arranged.
Tuningout lower contact 13 bottoms connect production tree.When polished rod is reciprocating, last seal 4 is in running order, play the sealing polished rod, lower seal 7 is in off working state, by adjusting the radial position of tuningout top connection, tuningout lower contact, the center of seal is overlapped with the center of polished rod, and connect 13 under the tuningout and do not overlap, prevent polished rod and seal eccentric wear.After last seal or the wearing and tearing of lower seal part, under spring action, can compensate automatically, make it still be in sealing state, through after the long-time seal operation, if last seal 4 has damaged when needing to change, take anti-rotation pin 10 away, rotatory sealing chamber 5, make lower seal 7 be in sealing state, can replace with seal 4.
