Abstract
A kind of well head robs the Rapid connecting bolt of spray, aperture is arranged at the lower part of screw rod, through slot, symmetrically placed two panels limit is fast in the through slot, it limits fast lower part and is in the aperture lower part for being connected to screw rod by pin shaft, spring is installed between two panels limit is fast, spring by two panels limit fast outside pop-up through slot, make to limit fast lower platform and be seated on the lower plane of through slot, limiting fast outside is taper, the big lower end in the upper end is small, screw rod is downwardly into well head upper body, in the connecting hole of well head lower body, the top coupling nut of screw rod, two panels limits on the lower end surface for the ring flange that fast upper surface is stuck in well head lower body, spring flicks limited block after limited block reaches well head lower body, twisting nut in screw rod upper end can be by well head upper body, well head lower body links into an integrated entity, energy Fast Installation bolt, reduce the time of installation bolt, The requirement of installing wellhead device when meeting blowout, can prevent gas blowout accident, have significant economic benefit and social benefit.
Description
Technical field
The utility model is the equipment for installing oilfield oil well wellhead assembly, is the quick connection spiral shell that a kind of well head robs spray
Bolt.
Background technique
The oil-water well well head in oil field is made of being connected with as some special-purpose members, and oil-water well is in operation period
When, wellhead assembly is dismantled.Blowout can occur for the oil-water well having in operation process, when thering is blowout to show or blowout occurring,
Installing wellhead device is needed, so that oil-water well is in state of a control, avoids or prevent blowout.Installing wellhead device is exactly quickly by well
Mouth device has been connected not with bolt group.But current wellhead assembly connects bolt group by the bolt of TBE (threaded both ends) and is connected to two
The nut at end forms, and is first through bolt in the connecting hole of two components of wellhead assembly, then in the both ends band of double public bolts
Top nut, then nut is tightened is just able to achieve installation well head.From the above, it can be seen that the connection bolt of current wellhead assembly
Quick requirement is not achieved in connection when in use, the requirement of installing wellhead device when not being able to satisfy blowout.
Summary of the invention
The purpose of this utility model is the Rapid connecting bolt for designing a kind of well head and robbing spray, overcomes above-mentioned ask
Topic, energy Fast Installation bolt, reduces the time of installation bolt, and the requirement of installing wellhead device when meeting blowout prevents blowout thing
Therefore occur.
Purpose of the utility model is realized as follows: include well head upper body, screw rod, nut, spring, limit fast, pin shaft,
Well head lower body, well head upper body are seated on well head lower body, and the connecting hole on well head upper body, well head lower body is overlapped, and the top of screw rod has
Aperture, through slot are arranged at external screw thread, the lower part of screw rod, and symmetrically placed two panels limit is fast in the through slot, limit at fast lower part
The lower part of screw rod is connected to by pin shaft in the aperture, spring is installed between two panels limit fastly, spring limits two panels fast
Outside be ejected into outside the through slot, make to limit fast lower platform and be seated on the lower plane of through slot, limiting fast outside is
Taper, the big lower end in the upper end is small, screw rod be downwardly into well head upper body, well head lower body connecting hole in, the top of screw rod connects spiral shell
Cap, two panels limit on the lower end surface for the ring flange that fast upper surface is stuck in well head lower body.
Fast screw rod is limited from well head upper body, the connection of well head lower body the beneficial effects of the utility model are: will install
It being downwardly into hole, hole wall compressing limited block is contracted to less than aperture, and spring flicks limited block after limited block reaches well head lower body,
Well head upper body, well head lower body can be linked into an integrated entity by twisting nut in screw rod upper end, and therefore, the utility model can be connected quickly
Wellhead assembly, can Fast Installation bolt, reduce the time of installation bolt, the requirement of installing wellhead device when meeting blowout can be with
Gas blowout accident is prevented, there is significant economic benefit and social benefit.
Detailed description of the invention
Fig. 1 is the installation diagram of the utility model.
Specific embodiment
1 pair of the embodiments of the present invention is illustrated with reference to the accompanying drawing.
As shown in Figure 1, the embodiments of the present invention include well head upper body 1, screw rod 2, nut 3, spring 5, limit it is fast 6,
Pin shaft 7, well head lower body 8, well head upper body 1 are seated on well head lower body 8, and the connecting hole on well head upper body 1, well head lower body 8 is overlapped, spiral shell
External screw thread is arranged at the top of bar 2, and aperture 9, through slot 4 are arranged at the lower part of screw rod 2, and symmetrically placed two panels limit is fast in the through slot 4
6, the lower part of limit fast 6 is in the inner lower part that screw rod 2 is connected to by pin shaft 7 in aperture 9, installs between two panels limit fast 6
Spring 5(spring 5 is in the groove of limit fast 6, will not fall off), the outside that two panels limits fast 6 is ejected into described by spring 5
Outside through slot 4, it is seated at the lower platform for limiting fast 6 on the lower plane of through slot 4, the outside of limit fast 6 is taper, under the upper end is big
Hold it is small, screw rod 2 be downwardly into well head upper body 1, well head lower body 8 connecting hole in, the top coupling nut 3 of screw rod 2, two panels limit
Fast 6 upper surface is stuck on the lower end surface of the ring flange of well head lower body 8.
The outside for limiting fast 6 is taper, and the big lower end in the upper end is small, its lower end shape is less than well head upper body 1 when Fig. 1 state
Connecting hole, can from well head upper body 1, well head lower body 8 connecting hole in be downwardly into, two panels limits fast 6 and reaches well head lower body 8
After below connecting hole cannot from well head upper body 1, well head lower body 8 connecting hole in come out, tightening nuts 3 generate axial force by two
Piece limit fast 6 undertakes.
