Description
Technical field
The utility model relates to a kind of oil field pipe plugging devices, belong to machinery equipment field.
Background technique
Usually need to install oil field pipe in oil field in oil field geologic work, the port of oil field pipe is sometimes for making
It is blocked with plugging device.Existing plugging device mostly uses thread forms to connect with oil field pipe greatly, installs cumbersome.
Summary of the invention
The utility model provides a kind of oil field pipe plugging device, by the way that inserting with preloading spring is arranged in lid portion inside
Pin, and corresponding pin hole is opened up in oil field pipe side, it is convenient to lid is fixedly mounted on oil field pipe.
The technical solution of the utility model is: a kind of oil field pipe plugging device, including cylinder-shaped lid open at one end, lid
Sealing column is equipped at body center, sealing column is uniformly provided with preloading spring at center in outwardly convex shape at center, lid inner wall,
Preloading spring end is respectively and fixedly provided with cylinder plugs, and the head of bolt is hemispherical, and bolt head is directed to sealing column
Axis.
The lid is made of stainless steel.
The sealing column is manufactured by anti-corrosive rubber material, and sealing column is fixed by screws in lid portion inside.
By spring steel making, preloading spring is fixed with lid and bolt respectively by welding for the bolt and preloading spring
Connection.
The preloading spring is equipped with four.
The beneficial effects of the utility model are: being uniformly provided with four preload bullets at the lid inner wall center of the utility model
Spring, four preloading spring ends are respectively and fixedly provided with cylinder plugs.Four corresponding pin holes are opened up in oil field pipe side, are installed
When sealing column can be clogged to the inner wall of oil field pipe, push lid, after bolt alignment pins hole, preloading spring can be by bolt
It is fixed in push-in pin hole, it is convenient to lid is fixedly mounted on oil field pipe, and can ensure that lid will not be easily
It is slid from oil field pipe.
Detailed description of the invention
Fig. 1 is the top view of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
Each label in figure: 1-lid, 2-sealing columns, 3-bolts, 4-preloading springs.
Specific embodiment
Embodiment 1: as shown in Figs. 1-2, a kind of oil field pipe plugging device, including cylinder-shaped lid 1 open at one end, lid
Sealing column 2 is equipped at 1 center, sealing column 2 is uniformly provided with preload bullet at 1 inner wall center in outwardly convex shape at center, lid
Spring 4,4 end of preloading spring are respectively and fixedly provided with cylinder plugs 3, and the head of bolt 3 is hemispherical, and 3 head of bolt is directed to
The axis of sealing column 2.
It is made of stainless steel it is possible to further which the lid 1 is arranged.
It is manufactured it is possible to further which the sealing column 2 is arranged by anti-corrosive rubber material, sealing column 2 is fixed by screw
Inside lid 1.
It is possible to further which the bolt 3 and preloading spring 4 is arranged by spring steel making, preloading spring 4 passes through welding
It is fixedly connected respectively with lid 1 and bolt 3.
It is possible to further which the preloading spring 4 is arranged equipped with four.
The use process of the utility model is: opening up four bolts corresponding with bolt 3 in matched oil field pipe side
Hole, and the depth of pin hole is equal to the round end radius of bolt 3.Sealing column 2 can be clogged to the inner wall of oil field pipe when installation, pushed
Lid 1, after 3 alignment pins hole of bolt, bolt 3 can be pushed into pin hole and fix by preloading spring 4, it is convenient to will cover
Body 1 is fixedly mounted on oil field pipe, and can ensure that lid 1 will not slide from oil field pipe easily.It can when needing to remove
Directly lid 1 is extracted, since the head of bolt 3 is spheroidal, and the depth of pin hole is equal to the round end radius of bolt 3, inserts
Pin 3 can skid off after by pulling force from pin hole, can remove lid 1 from oil field pipe.Novel oilfield pipeline envelope
Stifled device installation and dismounting are very convenient.
The specific embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the utility model is not
Be limited to above embodiment, within the knowledge of a person skilled in the art, can also do not depart from it is practical
Various changes can be made under the premise of novel objective.
