The utility model discloses an inside has the cylinder type rifle head of cross oilhole to insert the interior oiling of oil pipe box, screw thread oil is not not beyond the scope of the hourglass when adopting the spring compression casing to make the operation, adopt the rubber scraper ring to make screw thread oil paint evenly to reach and paint even, fuel -efficient, efficient mesh.
Description
Technical field
The utility model relates to a kind of dope application device, belongs to petroleum industry underground operation tool technical field.
Background technology
Oil field is in well during lower oil pipe operation, and will get up the screwed connection of oil pipe one by one G.I.H, before screwed connection, will smear dope on oil pipe thread, play a part to protect screw thread prevent screw thread adhesion and get rusty.The method of smearing at present dope on oil pipe box is that artificial brush is stained with dope and spreads upon on oil pipe box, and this method is affected by human factors comparatively large, there will be the problem of smearing inequality.Some screw threads can not get the protection of dope, and cause oil pipe thread short for service life, make oil well production cycle time, oil well needs frequent workover treatment, and increase workover cost, need to change large dipping tube, economic loss is serious.Also make work operations labour intensity large by manually smearing dope, inefficiency, job scheduling is slow.
The patent No. is a kind of dope application device of 201220267632.0, and can carry out dope to the pin thread of oil pipe and smear, simple to operate, operating efficiency is high, there is not dope and smears uneven problem, but there is the shortcoming that cannot use the box of oil pipe.
Utility model content
The utility model technical issues that need to address are that artificial brush is stained with dope and is smeared oil pipe box, there will be and smear inequality, labour intensity is large, the shortcomings such as inefficiency, object be to provide one smear even, fuel-efficient, efficiency is high, the dope application device that can use oil pipe box.
The utility model is become with rifle head group by nozzle, oil guide pipe, housing, and housing is half-open shape of the mouth as one speaks cylinder, and there is outer openend, and blind end center has through hole; Rifle head is column type nylon rod, is placed in housing, and one end corresponding with the through hole of housings close end has central oil passage, and has the cross oilhole be communicated with its central oil passage, and central oil passage is provided with screw thread; Oil guide pipe is hollow circular-tube, and threaded one end is connected on the central oil passage of rifle head, and other end screw thread is threaded with nozzle.
The cross oilhole both sides of described rifle head are provided with O-ring seal and vulcanite scraper oil ring.
Described oil guide pipe is welded with circular baffle plate, the oil guide pipe between circular baffle plate and housing is provided with spring.
Described shell nozzle end outer is provided with seal gasket.
The utility model adopts oiling in the inner column type rifle head insertion oil pipe box having cross oilhole; When adopting spring-compressed housing to make operation, dope does not leak outside; Adopt vulcanite scraper oil ring that dope is smeared evenly, thus reach and smear even, fuel-efficient, that efficiency is high object.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart;
Fig. 2 is utility model works state diagram.
Detailed description of the invention
Composition graphs 1, Fig. 2, be described further the utility model.
As shown in Figure 1, the utility model is made up of nozzle 1, oil guide pipe 2, housing 5 and rifle head 9, and housing 5 is half-open shape of the mouth as one speaks cylinder, and there is outer openend, and blind end center has through hole; Rifle head 9 is column type nylon rod, is placed in housing 5, and one end corresponding with the through hole of housing 5 blind end has central oil passage, and has the cross oilhole be communicated with its central oil passage, and central oil passage is provided with screw thread; Oil guide pipe 2 is hollow circular-tube, and threaded one end is connected on the central oil passage of rifle head 9, and other end screw thread is threaded with nozzle 1.
The cross oilhole both sides of described rifle head 9 are provided with O-ring seal 6 and vulcanite scraper oil ring 8.
Described oil guide pipe 2 is welded with circular baffle plate 3, the oil guide pipe 2 between circular baffle plate 3 and housing 5 is provided with spring 4.
Described outer, housing 5 openend is provided with seal gasket 7.
As shown in Figure 2, the utility model operationally, housing 5 first pushes up on the outer face of oil pipe box 10 by hand-held oil guide pipe 2, then is pushed in oil pipe box 10 by rifle head 9, and dope is injected in oil pipe box 10 by the cross oilhole of rifle head 9 and smears screw thread by last operation nozzle 1.Screw thread in vulcanite scraper oil ring 8 deformation retract sealing oil pipe box 10, the seal gasket 7 of housing 5 openend seals the outer face of oil pipe box 10, the opposite side of the O-ring seal 6 sealer gun head on rifle head 9, forms a sealed cavity, ensures that the dope injected does not leak outside.It is reliable that spring 4 ensures shell 5, seal gasket 7 is pressed on the sealing of oil pipe box 10 outer face.When extracting rifle head 9 in oil pipe box 10, the expansion of vulcanite scraper oil ring 8 recoverable force can make the dope in oil pipe box 10 smear evenly, unnecessary dope can be brought back in housing 5 simultaneously and seal.When transfering to rifle head 9, spring 4 can promote shell 5 and continue to be enclosed within outside rifle head 9, ensures that the unnecessary dope that vulcanite scraper oil ring 8 scrapes does not leak outside.
