Description
Technical field
The utility model occurs entering the joint of spray of robbing when oil pipe emits spray during being related to a kind of oil-water well maintenance activity,
Specifically related to a kind of operation well oil pipe emits spray Quick blowout control joint.
Background technology
At present, in the oil in oil field, water well operation maintenance process, spray situation, one are emitted when playing oil pipe or lower oil pipe
As be all using the stop valve make-up with universal oil connection is connected in the tubing coupling for emitting spray, so to the closure of oil pipe
After turn off stop valve, just terminate the operation that oil pipe robs spray, because the oil temperature of ejection is high, oil gas upwards, send forth and cause to surrounding
Severe operational environment, or even people can not breathe and sight is influenceed, so it is difficult to being directed at screw thread in a short time.Therefore it is original
Robbing spray method, it has the disadvantage：With duration, operation difficulty is big, seriously polluted, to operating personnel the infringement that causes is big.
The content of the invention
In order to overcome oil well operation oil pipe of the prior art emit spray rob spray mode duration, cause it is seriously polluted, right
Operating personnel's damages big deficiency, and the utility model provides a kind of operation well oil pipe and emits spray Quick blowout control joint, can be quick
Oil gas is prevented to send forth everywhere, it is simple to operate, quick, small are damaged to operating personnel.
Its technical scheme is：A kind of operation well oil pipe emits spray Quick blowout control joint, including joint body, guiding cover and hand
Wheel, one end of joint body is provided with pin thread, and its other end is provided with box, and the handwheel is surround by dowel is welded on guiding cover
Periphery, the one end of the joint body with pin thread is located in guiding cover, and it is outer that one end with box is located at guiding cover, and connects
The middle part of head body is connected to guiding cover one end with one heart；Perisporium of the joint body with pin thread one end is provided with pressure relief opening.
Wherein, the middle part of the joint body with guiding cover one end is by screw thread or is welded to connect.
The pressure relief opening is rectangle structure, and it is set to 2-6 and is evenly distributed on the week that joint body carries pin thread one end
On wall.
There is at least three gusset on the inwall of the guiding cover, the end of gusset takes the form of inclined plane structure.
The beneficial effects of the utility model are：The utility model coordinates the stop valve for being already at closed mode to use, only
Rotation hand wheel is needed, whole operation process operation is simple, quick, time saving, laborsaving；Quickly the oil gas for emitting spray can be covered
Only spray downwards, prevents oil gas from sending forth everywhere, operating environment is improved, and operating personnel can be made to be damaged from oil gas.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the utility model；
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
A kind of 1-Fig. 2 of reference picture, operation well oil pipe emits spray Quick blowout control joint, including joint body 1, guiding cover 2 and hand
Wheel 3, one end of joint body 1 is provided with pin thread, and its other end is provided with box, and the handwheel 3 surround to be welded on and led by dowel 4
Draw the periphery of cover 2, the one end of the joint body 1 with pin thread is located in guiding cover 2, and one end with box is located at guiding cover
Outside 2, and the middle part of joint body 1 is connected to one end that guiding covers 2 with one heart by screw thread or welding；The joint body 1 is carried
The pressure relief opening 5 provided with 2-6 rectangle structures is uniformly distributed on the perisporium of pin thread one end.2 cylindrical cups of the guiding cover
There is at least three gusset 6 on shape structure, its inwall, the end of gusset 6 takes the form of inclined plane structure, can guide the oil pipe top of spray to be robbed
The section hoop in portion smoothly enter guiding cover 2 in, the external screw thread for the limitation scope energy righting joint body 1 that the inner face of gusset 6 is surrounded and
The interior spiral shell of section hoop aligns contact at the top of oil pipe.
During operation, a stop valve being closed is connected in female end of the joint body 1 provided with box first,
When oil pipe emits spray, the guiding cover 2 of the utility model device is covered on oil pipe section hoop, oil, gas be able to not will up spray again, and
It is that the spatial channel guided in cover 2 between each gusset 6 is entered by the pressure relief opening 5 opened up on the pin end perisporium of joint body 1,
Then the bottom from guiding cover 2 sprays downwards, as long as at this moment rotation hand wheel 3 drives guiding cover 2 and joint body 1 to rotate, makes to connect
The external screw thread of the head pin end of body 1 is screwed in into section hoop, when the pressure relief opening 5 opened up on the pin end perisporium of joint body 1 is by whole
During the internal thread of precession section hoop, pressure relief opening 5 is blocked, as long as then screw thread again, oil gas will have been sealed thoroughly, from
And complete to rob the task of spray.
The utility model coordinates the stop valve for being already at closed mode to use, it is only necessary to rotation hand wheel, whole behaviour
Make process operation simple, quick, it is time saving, laborsaving；The oil gas for emitting spray quickly can be covered into only spray downwards, prevent oil gas from spraying everywhere
Dissipate, operating environment is improved, operating personnel can be made to be damaged from oil gas.
