Abstract
The production tree pressure testing plugging device of the utility model, the stifled ball including valve body and in valve body；It is characterized in that：The inside of the valve body is the conical cavity that from top to bottom size is gradually reduced, and stifled ball is located in conical cavity；There are two auricles for the connection of valve body upper edge, block up on ball and are fixed with connecting rod；The outer diameter of the valve body is equal with the diameter of Christmas tree big four joint inner cavity, and the diameter of the stifled ball is equal with the diameter of cross section in conical cavity.The production tree pressure testing plugging device of the utility model, during use, by the way that valve body is placed in big four internal cavities, by impacting connecting rod, so that stifled ball generates compression to valve body so that the outer wall of valve body and the inner wall of big four are in close contact, and realize the sealing to big four lower port and oil well time, during so that carrying out pressure test to production tree, oil well will not be adversely affected.
Description
Technical field
The utility model is related to a kind of production tree pressure testing plugging device, more specifically, more particularly to it is a kind of can be to big by four
The production tree pressure testing plugging device that logical lower end is blocked.
Background technology
Production tree is both provided on production platform or drill ship, to realize the oil recovery to flowing well or machine-pumped oil well, production tree
Installation is complete or repair replace component after, be required to carry out pressure testing to it, with ensure it is subsequent safety recover the oil.During pressure testing, apply
The pressure added in production tree would generally be transferred in oil well, and oil well is adversely affected, if can be big from production tree bottom
Four-way is clogging by production tree, then only can carry out pressure testing to production tree, avoid adversely affecting producing well.
Invention content
The shortcomings that the utility model is in order to overcome above-mentioned technical problem, big four lower end can be blocked by providing one kind
Production tree pressure testing plugging device.
The production tree pressure testing plugging device of the utility model, the stifled ball including valve body and in valve body；It is characterized in that：Institute
The inside for stating valve body is the conical cavity that from top to bottom size is gradually reduced, and stifled ball is located in conical cavity；Valve body upper edge is connected with two
A auricle blocks up on ball and is fixed with connecting rod；The outer diameter of the valve body is equal with the diameter of Christmas tree big four joint inner cavity, the stifled ball
Diameter is equal with the diameter of cross section in conical cavity.
The production tree pressure testing plugging device of the utility model, the valve body are rubber material, and auricle is rubber, fabric or metal
Material blocks up ball and uses plastics or metal material.
The production tree pressure testing plugging device of the utility model, the outer end of the connecting rod are fixed with to match with Wrench
Hexagonal prism.
The beneficial effects of the utility model are：The production tree pressure testing plugging device of the utility model, by valve body, stifled ball, connecting rod
It is formed with auricle, stifled ball is located in valve inner conical cavity, in use, by the way that valve body is placed in big four internal cavities, leads to
Cross impact connecting rod so that stifled ball generates compression to valve body so that the outer wall of valve body and the inner wall of big four are in close contact, and are realized
Sealing to big four lower port and oil well time so that when carrying out pressure test to production tree, it is unfavorable to be caused to oil well
It influences.

Fig. 3 is the vertical view of the production tree pressure testing plugging device of the utility model；
Fig. 4 is the sectional view of Section A-A in Fig. 3；
Fig. 5 is the usage state diagram of the production tree pressure testing plugging device of the utility model.
In figure：1 valve body, 2 stifled balls, 3 connecting rods, 4 auricles, 5 inclined surface, 6 conical cavities, 7 hexagonal prisms, 8 big fours, 9 upper flanges,
10 lower flanges, 11 upper ports, 12 lower ports, 13 left ports, 14 right ports.
Specific embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, front view, the left side of the production tree pressure testing plugging device of the utility model is set forth
View and vertical view, Fig. 4 give the sectional view of Section A-A in Fig. 3, the production tree pressure testing plugging device of shown the utility model
It is made of valve body 1, stifled ball 2, connecting rod 3 and auricle 4, shown valve body 1 is cylindrical shape, and the inside of valve body 1 is from top to bottom
The conical cavity 6 that size is gradually reduced, stifled ball 2 are located in conical cavity 6.The upper edge of valve body 1 is fixedly connected there are two auricle（4）, block up
Ball 2 is fixed with 3 phase of connecting rod, and the upper end of connecting rod 3 is fixed with hexagonal prism 7, and hexagonal prism 7 can realize the cooperation with the tools such as spanner.
The outer diameter of shown valve body 1 is equal with the intracavity diameter of production tree bottom big four 8, so that valve body 1 is filled in valve body 1
In inner cavity.The diameter of stifled ball 2 is equal with the diameter of cross section in conical cavity 6 so that stifled ball 2 is in conical cavity 6, and can not
It falls, realizes the closure to 8 internal cavities of big four.
Shown valve body 1 use rubber material, so as in stifled ball 2 under the squeezing action of valve body 1, the outer wall of valve body 1 can be made
It is adjacent to inside big four 8, realizes plugging action.Plastics or metal material can be used in shown stifled ball 2, so as to block up ball 2 to valve body 1 into
Row compression.Auricle 4 is connect using rubber, fabric or metal material as long as auricle 4 can be realized with the secured of valve body 1.
As shown in figure 5, giving the usage state diagram of the production tree pressure testing plugging device of the utility model, shown production tree is big
The upper and lower side of four-way 8 is respectively arranged with upper flange 9, lower flange 10, and the upper and lower side of big four 8 is respectively upper port 11 and lower port
12, the left and right sides is respectively left port 13 and right port 14.In use, first fill in valve body 1 in 8 internal cavities of big four,
And ensure that valve body 1 is located at the lower section of left port 13 and right port 14, and two auricles 4 do not block left port 13 and right port 14；So
Stifled ball 2 is put into conical cavity 6 afterwards, 4 upper end of auricle is pushed down in upper end, by impacting hexagonal prism 7, stifled ball 2 is made tightly to press in valve
On the inner wall of body 1, and the outer wall by pressure holding position of valve body 1 is caused to be close to big four inner wall, to realize to 8 lower port of big four
11 sealing.In this way, pressure test can be carried out to production tree, without being impacted to producing well.
