Description
Technical field
The utility model relates to the safety protection fields of wellhead equipment, are specifically related to a kind of removable well head vent valve guarantor
Protection unit.
Background technique
Vent valve is the component that oil extraction operation personnel often operate, in level pressure air-bleed operation, if it is larger in casing pressure
In the case where operated, there is very big risk, especially adjust jackscrew screw-in depth it is shallower in the case where, or even meeting
Occur adjusting jackscrew and flying out causing the situation of safety accident.
Currently, the vent valve of most of well heads is all not equipped with safety device, staff is merely able to by virtue of experience
It is operated, if especially operated in the case where no decompression because careless and inadvertent cause safety accident, work people
The personal safety of member is unable to get guarantee, does not meet the stable objective of oil recovery production safety.
Utility model content
The purpose of this utility model is in view of the above technical defects, to provide a kind of removable well head vent valve protective device,
Solving the problems, such as current operating process, there are security risks, avoid staff that safety accident occurs.
Technical solution: a kind of removable well head vent valve protective device, it includes the positioning for being welded on the upper surface of valve body
Set, setting locating rod are fastened on the inside of the positioning sleeve, a fixing axle are transversely arranged across the locating rod, described
Backplate is arranged in fixing axle, connecting rod is fixedly installed in the lower part of the backplate；It is to be arranged in the connecting pipeline of valve body by bolt
Support rod is fixedly installed in the clamp of fastening, the top of the clamp along longitudinal direction, and the top of the support rod is arranged positioning plate, passes through
Push rod is arranged in the positioning plate, and in the tail portion of push rod, setting shaft is flexibly connected the connecting rod.
External screw thread is arranged in the head of the push rod, and the push rod is fastened on the positioning plate by setting locking nut.
The utility model has the advantages that the utility model is using using backplate as protecting component, it can when staff operates
The generation of safety accident is effectively avoided, and the utility model structure is simple, it is easy to operate, it can also be torn open in the case where not using
Under.
Detailed description of the invention
Attached drawing 1 is the schematic view of facade structure of the utility model；
Attached drawing 2 is the planar structure schematic diagram of the utility model.
Specific embodiment
Referring to attached drawing 1 and attached drawing 2, a kind of removable well head vent valve protective device, it includes be welded on valve body 11 upper
The positioning sleeve 10 of end face, setting locating rod 9 are fastened on the inside of the positioning sleeve 10, are transversely arranged across the locating rod 9
One fixing axle 7, is arranged backplate 8 in the fixing axle 7, and connecting rod 12 is fixedly installed in the lower part of the backplate 8；It is in valve body
The clamp 2 by bolt fastening is arranged in 11 connecting pipeline 1, support rod 3, institute is fixedly installed in the top of the clamp 2 along longitudinal direction
The top setting positioning plate 4 for stating support rod 3, passes through the positioning plate 4 and push rod 6 is arranged, and in the tail portion of push rod 6, setting shaft 13 is living
The dynamic connection connecting rod 12；External screw thread is arranged in the head of the push rod 6, and the push rod 6 is fastened on described by setting locking nut 5
On positioning plate 4.
The utility model is to avoid adjusting jackscrew 14 to fly out under stress using backplate 8 to cause the generation of safety accident, is had
During gymnastics is made, staff only needs to push push rod 6, makes backplate 8 at level angle, can be used after tightening locking nut 5
Spanner operation adjusts jackscrew 14, even if staff is because carelessness safety accident, Er Qie will not occur without emptying casing pressure
Replacement vent valve or connecting flange and other without using that the utility model can be removed in the case where the utility model, only
11 top of valve body retains the positioning sleeve 10 of welding.
