Description
Technical field
The utility model is related to a kind of pressure testing blocking device, specifically a kind of simple in construction, easy to operate, sealing effect
Really good, blanking plug is easily removed, the replaceable pressure testing blocking device for blocking device assembly.
Background technology
Calker when blanking plug for testing pressure is drilling well, mining site casing string and preventer group pressure testing.And sleeve pipe is being tried
During pressure, blanking plug is set in sleeve pipe, prevents liquid or gas from leaking, overpressure is maintained to a certain degree.It is existing
Blanking plug be made up of fishing head, oil nozzle, main body, sealing ring, plug, profile is respectively to be set above and below cylinder, liquid pass hole
Be equipped with sealing ring, but the scalable amount very little of external diameter of sealing ring, remove very inconvenient, sealing ring is easily routed up, make to remove be difficult into
OK, and sealing effectiveness is also poor.Traditional blanking plug for testing pressure is that different gage cannulas need the blanking plug for testing pressure of different size, very
It is inconvenient.
Utility model content
The purpose of this utility model be in view of the deficienciess of the prior art, provide a kind of simple in construction, it is easy to operate, it is close
Envelope effect is good, and blanking plug is easily removed, the replaceable pressure testing blocking device for blocking device assembly.Including main body sleeve；The main body set
Extension bar is provided with cylinder；Sealing ring is provided with below the upper extension bar；Blocking device assembly is provided with the main body sleeve；Institute
Stating blocking device assembly includes housing；Two bodies are provided with the housing；Ringfeder is provided between described two bodies；It is described
Main body sleeve lower end is provided with lower interface；First through hole is provided with the upper extension bar；It is provided with the main body sleeve body
First cavity；The second through hole is provided with the housing；The second cavity is provided with the ringfeder；Described first through hole 6 with
First cavity 7 is connected；The second described through hole 8 is connected with the second cavity 9.
Wherein, the material of the sealing ring is rubber.
Wherein, the material of the ringfeder is rubber.
Wherein, the main body sleeve is connected through a screw thread with upper extension bar.
Wherein, the main body sleeve is connected through a screw thread with blocking device assembly.
Beneficial effect：The utility model is simple in construction, be easily installed, good sealing effect, blanking plug are removed conveniently, using rising
Set blocks and solves the problem of sealing ring is easily routed up well；Block device assembly to be connected with main body bush whorl, can change not
Same model, it is adaptable to which the sleeve pipe of different caliber sizes, applicability is wider.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, the present embodiment is with the utility model
It is lower premised on technical scheme to be implemented, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality
With new scope.
As shown in figure 1, a kind of pressure testing blocking device, including：Main body sleeve 1；Extension bar is provided with the main body sleeve 1
2；The lower section of upper extension bar 2 is provided with sealing ring 3；Blocking device assembly 4 is provided with the main body sleeve 1；The blanking plug group
Part includes housing 4-1；Two body 4-2 are provided with the housing 4-1；Ringfeder 4- is provided between described two body 4-2
3；The lower end of main body sleeve 1 is provided with lower interface 5；First through hole 6 is provided with the upper extension bar 2；1, the main body sleeve
The first cavity 7 is provided with body；The second through hole 8 is provided with the housing 4-1；The second cavity is provided with the ringfeder 4-3
9.Described first through hole 6 is connected with the first cavity 7；The second described through hole 8 is connected with the second cavity 9.
The material of the sealing ring 3 is rubber；Ringfeder 4-3 material is rubber；Main body sleeve 1 passes through spiral shell with upper extension bar 2
Line is connected；Main body sleeve 1 is connected through a screw thread with blocking device assembly 4.
Main body sleeve 1 of the present utility model is connected through a screw thread with upper extension bar 2；Main body sleeve 1 passes through with blocking device assembly 4
Threaded connection.When the sleeve pipe applied to different bores, upper extension bar 2 can be unloaded together with sealing ring 3, then change different shaped
Number blocking device assembly 4.
In use, drilling rod is connected to main body sleeve upper end by upper extension bar, pressure test tool is connected to main body by lower interface
Sleeve lower end.Then blanking plug is lowered into the sleeve pipe in well by drilling rod, be connected with the drilling rod at well head
Valve is provided with compression pump, compression pump.After in blanking plug tripping in sleeve pipe, the gas closed in the valve being located at well head, well
Body or liquid are entered in sleeve pipe and entered again by the second through hole in the second cavity of ringfeder, and gas or liquid rise by ringfeder
Rise, until rising ringfeder is tightly withstood on internal surface of sleeve pipe, prevent gas to be flowed into the sleeve pipe of ringfeder upper end, positioned at main body
The pressure test tool of sleeve lower end just can carry out underground pressure testing to sleeve pipe exactly.After pressure testing is complete, by the valve at well head
Door is opened, and the gas or liquid being sealed in ringfeder first pass through the second through hole flow direction external world, by between interface and pressure test tool
Gap, first through hole, the gas in the first cavity or liquid flow outwardly, thus complete pressure leak process, treat pressure release complete
Drilling rod, which is above carried, afterwards to propose blanking plug from sleeve pipe.
