Description
Technical field
The utility model relates to a kind of cassette mandrel boll-weevil hanger, is to be used for hanging oil pipe, the device of Seal Oil tube head body endoporus fitting face, upper flange endoporus fitting face.
Background technology
It is to finish by a plurality of jackscrew groups that present known boll-weevil hanger is fixed on the tubing head body, need a plurality of top wire holes of processing on tubing head, also to design the jackscrew sealing device, complex structure, complex operation, and the top wire hole hidden danger of exist leaking, boll-weevil hanger and upper flange cooperation place are rubber seal in addition, corrosion-resistant and anti-aging aspect have defective.
Summary of the invention
The purpose of this utility model is: a kind of cassette mandrel boll-weevil hanger is provided, and simplified structure, handled easily solves with a plurality of jackscrew groups boll-weevil hanger is fixed on the deficiency on the tubing head body and the defective of rubber seal.
Technical solution of the present utility model is: this boll-weevil hanger mainly is made up of boll-weevil hanger body, split ring collar, metal o-ring, the upper end endoporus of boll-weevil hanger body is established tubing round thread, processing one cannelure on the cylindrical of boll-weevil hanger body, the split ring collar is installed in the boll-weevil hanger body cannelure, and metal o-ring is installed in the upper end of boll-weevil hanger body.
In the utility model cassette mandrel boll-weevil hanger, metal o-ring is installed in boll-weevil hanger body upper end, it is hemispheric annular protrusion that the outer round surface of this metal o-ring has designed the cross section, be interference fit between metal o-ring and boll-weevil hanger body, the upper flange, boll-weevil hanger body, upper flange, metal o-ring be assembled together by bolt, the nut that connects upper flange and tubing head body.
In the utility model cassette mandrel boll-weevil hanger, on the periphery of metal o-ring, rubber seal is arranged; On the upper and lower side cylindrical of boll-weevil hanger body, rubber seal is arranged respectively; The control valve line interface is installed on the boll-weevil hanger body.
During use, split ring collar step surface contacts with cannelure upper surface on the tubing head body, and split ring collar lower surface contacts with boll-weevil hanger cylindrical cannelure lower surface, so just boll-weevil hanger is fixed on the relevant position on the tubing head body.
The utility model is fixed on the boll-weevil hanger body on the tubing head body by the split ring collar, and by metal o-ring sealing and tubing head body, upper flange fitting face, simple in structure, easy to operate, sealing effectiveness is lasting.
