Description
Technical field
The utility model relates to the protection fields of wellhead equipment, are specifically related to a kind of wellhead oil tree valve protection dress
It sets.
Background technique
The premise that effective protection is safety and stability production is carried out to wellhead oil tree valve.
On the one hand, valve exists by the danger of pirate of the open, can not only lower yield, but also it is higher to replace maintenance cost.
On the other hand, there is the danger accidentally injured in valve, and especially when carrying out the operation such as steam injection dosing, staff is usual
It will use sledgehammer and tighten or unload underground pipelines box cupling, be easy to accidentally injure lead screw and other valve members.
Utility model content
The purpose of this utility model is in view of the above technical defects, to provide a kind of wellhead oil tree valve protection device, solution
The certainly easily stolen technical problem opened and accidentally injured of wellhead oil tree valve.
Technical solution: a kind of wellhead oil tree valve protection device, including the small-bore cover that is welded with valve body and with
The heavy caliber cover that small-bore cover is threadedly coupled, which is characterized in that weld fixed plate, institute in the end face of the heavy caliber cover
The side for stating fixed plate opens up arc groove, and the surface of the fixed plate opens up strip groove, the internal activity setting of the strip groove
Pull rod, the upper end of the pull rod are fixedly connected with ball, and the top of the ball cooperates with the operation handle for being provided with magnetic tip, described
The lower end of pull rod is fixedly connected with elastic slice, and the elastic slice is fastened on the side of the fixed plate by screw, in the bottom of the elastic slice
Setting connecting rod is fixedly connected with key；Through-hole is arranged in the outer periphery of the small-bore cover, and the inner wall of the heavy caliber cover is opened
If groove.
The through-hole is aligned after the heavy caliber cover is screwed with the small-bore cover with the groove, to form use
In the cavity for accommodating the key.
The utility model has the advantages that the utility model structure is simple, and it is easy to operate, it can not only all avoid staff from accidentally injuring valve group
Part, and there is good anti-theft effect.
Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to attached drawing 1, a kind of wellhead oil tree valve protection device, including the small-bore cover 1 that is welded with valve body and
The heavy caliber cover 7 being threadedly coupled with small-bore cover 1, fixed plate 8 is welded in the end face of the heavy caliber cover 7, described solid
The side of fixed board 8 opens up arc groove 9, and the surface of the fixed plate 8 opens up strip groove 3, the internal activity setting of the strip groove 3
Pull rod 2, the upper end of the pull rod 2 are fixedly connected with ball 4, and the top of the ball 4 is matched with the operation handle 6 for being provided with magnetic tip 5
It closes, the lower end of the pull rod 2 is fixedly connected with elastic slice 14, and the elastic slice 14 is fastened on the side of the fixed plate 8, In by screw 15
The bottom setting connecting rod 10 of the elastic slice 15 is fixedly connected with key 11, and through-hole 13, institute is arranged in the outer periphery of the small-bore cover 1
The inner wall for the heavy caliber cover 7 stated opens up groove 12, the through-hole 13 and the groove 12 the heavy caliber cover 7 with it is described
Small-bore cover 1 is aligned after screwing, to form the cavity for accommodating the key 11.
The utility model is by small-bore cover 1 to achieve the purpose that valve member is avoided to be accidentally injured, while passing through osculum
Diameter cover 1 and heavy caliber cover 7, which cooperate, to be achieved the purpose that prevent to be had the prominent advantages that by pirate of the open, which is to pass through
The mode pulled makes key 12 be detached from the cavity that through-hole 13 and groove 12 are formed, when key 11 is embedded in the sky that through-hole 13 and groove 12 are formed
After chamber, key 11 can not be made to deviate from ball 4 using common instrumental purpose, push ball 4, ball 4 can be bonded with arc groove 9, pull ball 4
It can not be found again by means of force, the operation handle 6 with magnetic tip 5 only provided using the utility model is in a manner of pulling
Keep elastic slice 14 upwardly-deformed, to pull key 11 to deviate from by the connecting rod 10 connecting with elastic slice 14, and then screw off heavy caliber cover 7,
And the staff for not receiving pre-job training and other unwarranted personnel, it is not clear that this design, thus should
Utility model has good anti-theft effect.
The utility model still in development phase, has not been put to practical application at present, and because the utility model is submitted hastily,
Therefore many sport technique segments such as specific installation and operation are still needed to further improve.
