Abstract
The invention discloses a tire type puncture-proof eccentric packing box. The tire type puncture-proof eccentric packing box is formed by taking a packing cavity (1) as a main body; the outer wall of the packing cavity is provided with an aerating nozzle (18); a tire frame (6), a tire (8) and a packing (20) are arranged inside the cavity; an enclosed space is formed between the tire (8) and the inner wall of the packing cavity (1); the lower end of a thin pipe is connected integrally with a middle disk (4) of an eccentricity finding flange; a gland (10) and a pressure cap (12) are arranged above the tire (8) and the packing (20); and the pressure cap (12) and a set of puncture-proof packing box (16) are combined to construct a set of complete tire type puncture-proof eccentric packing box. When an inflation sleeve is used for inflating air into the cavity (19) and the enclosed space of the tire (8) through the aerating nozzle (18), the tire (8) wall plumps up towards the center through a vent hole (7) in the tire frame (6) along with the increase of the air amount, centering transverse pressure is applied to the packing (20), and the packing (20) is driven to clamp a polished rod tightly, so that the aim of sealing is fulfilled.
Description
Affiliated technical field
The present invention relates to a kind of rod-pumped well production tree packing box.
Background technology
At present, known packing box is packing mostly with the oil resistant rubber, and leaning on vertically, extruding rubber packing causes elastic deformation to hold polished rod realization sealing effectiveness tightly.This type packing box exists that low, the tight packing of packing utilization rate is frequent, sealing effectiveness is poor.Some high water-cut wells and coal seam water pumping gas production well, because the poor lubrication of water, polished rod has reduced the sealing effectiveness of packing box significantly to the serious wear of rubber packing.Utilize other material to do packing, but do not have elastic deformation to be difficult to realize sealing.
Summary of the invention
In order to overcome the deficiency of existing packing box, the present invention provides a kind of tire formula anti-stab eccentric packing box, and this packing box has improved not only in the past that packing box vertically pushes the defective that the oil resistant rubber packing exists, and can adopt inelastic materials to do packing.
The technical solution adopted for the present invention to solve the technical problems is: a pipe joint, the outer wall of pipe are equipped with a hole, and the outside in hole is airtight to connect a tire charging connector; There is the end lower end; Form cavity, the middle part has individual concave station, following middle part connecting a joint tubule on the bottom surface, and the lower end of tubule connects as one with the telophragma of looking for eccentric flange again; The hole that the center has polished rod to pass constitutes a complete packing cavity.Individual cast moulding bed is arranged in the packing cavity; Air-vent is arranged on the tube wall; The centre is installed with the tubulose tire that oil resistant rubber is processed, and the two ends of tire are joint rings, and it is turned up is enclosed within on the outer at moulding bed two ends; Tire cooperates the airtight annular space of formation through the sealed at both ends ring with the packing cavity inner wall, be packing in the middle of the tire.Insert in the concave station on the cavity bottom surface lower end of packing, and packing top exceeds a tire upper edge part.Being a gland above tire and the packing, also is a concave station in the middle of below the gland, and insert in the concave station on packing top, the hole that the center has polished rod to pass.Be a pressure-pad above the gland, be the cap type and be buckled on the gland that pressure-pad is connected with the packing cavity by screw thread, top is connecting the common packing box of a cover by a pipe joint, is equipped with outage on the middle part sidewall of pipe, forms anti-stab packing box, and the center is the hole that polished rod passes through.So with look for that eccentric flange is common to constitute the complete anti-stab eccentric packing box of tire formula of a cover.When using inflator, when in the confined space of packing cavity and tire, inflating, along with the increase of gas flow through charging connector; Impel tyre sidewall to heave through the air-vent on the cast moulding bed to the center; Packing is applied the lateral pressure to the center, impel packing to hold polished rod tightly, reach the purpose of sealing.
The invention has the beneficial effects as follows that vertical compressive strain of packing has changed over the pressure that laterally tightens to the center, compressed-air actuated elastic deformation amount is bigger than rubber, and packing can be non-elastic material, and is simple in structure.
