Description

A kind of plugging device for the connection of surface pipe double male joint
Technical field
The present invention relates to oil exploration and extraction technical field, leakage closure when being connected more particularly to surface pipe double male joint Device.
Background technology
In oil exploration & development field, widely used double male joint carries out the connection of oil pipe line.
But find in the application, when in use, the screwing position at both ends is it occur frequently that leakage, a side for double male joint Face causes oil liquid leakage to run damage, and the pressure loss in pipeline, on the other hand also becomes security risk.
For this leakage situation, widely used close measure is:Set in double male joint both ends junction upper and lower close Sealing assembly, fastener is set between upper and lower seal assembly, and upper and lower seal assembly, upper and lower sealing group are compressed using fastener The sealing ring that part is pressed further by seam crossing setting has the function that sealing and anti-leakage.
Currently used fastening means includes:
(1)Wedge compresses:Using sledgehammer, wedge is manually tapped, upper and lower seal assembly crush seal is driven using wedge Circle;
(2)Screwing screw is held out against:It is small to act on the pressure of upper and lower seal assembly, effect cannot be lasting.
Fastening means above is all to use mechanical presses mode, fully relies on the experience construction of operating personnel, reliability Difference, airtight quality are difficult to ensure that.
Moreover, most plugging construction needs to carry out in just cheating, side hole size is smaller, is unfavorable for the progress of construction.
This closure mode, can not accurately measure the pressure condition at closure, be unfavorable for installing blasting protection facilities, leave safety Hidden danger.
Utility model content
For defect existing in the prior art and deficiency, the purpose of this utility model is to provide it is a kind of it is safe and reliable, Easy to operation is used for surface pipe double male joint both ends connection leakage blocking device.
The technical solution of the utility model is as follows:
A kind of plugging device for the connection of surface pipe double male joint, including it is arranged at double male joint both ends junction Upper seal assembly and lower seal assembly, the seaming position of double male joint both ends junction are both provided with sealing ring, its feature It is:Hydraulic package is provided between the upper seal assembly and lower seal assembly, is driven after the hydraulic package injection pressure upper close Sealing assembly and/or the movement of lower seal assembly, and extrude corresponding sealed ring deformation closure.
Optionally, the inlet of each hydraulic package is connected with an injection device, and is injected and flowed by the injection device State resin.
Optionally, some hydraulic packages, each hydraulic package edge are provided between the upper seal assembly and lower seal assembly Surface pipe circumference uniform distribution is set.
Optionally, any hydraulic package includes at least a hydraulic cylinder, and the hydraulic cylinder includes outer cylinder body and inner cylinder body, Inner cylinder body back-off is arranged in outer cylinder body, and the inner cavity of two cylinder bodies communicates, and respectively with upper seal assembly and lower seal assembly It is connected.
Optionally, each cylinder chamber is all connected with being provided with hydralic pressure gauge.
The utility model has technical effect that:
The utility model between upper and lower seal assembly by setting hydraulic package, using being produced after hydraulic package injection pressure Movement drive the movement of upper and lower seal assembly, and extrude the sealing ring being arranged at the connecting sewing of double male joint both ends and be deformed To block connecting sewing, prevent leakage.
Hydraulic package is used to replace the driving such as wedge, screwing screw fashion of extrusion in the prior art, is greatly improved The force way and motion mode of upper and lower seal assembly, correspondingly, elastic seal ring at the connecting sewing of double male joint both ends by Power state and mode of texturing are obtained for huge improvement.
In the utility model, injection device is provided with hydraulic cylinder, fluid resin is injected simultaneously by hydraulic cylinder by injection device Driving hydraulic cylinder works.
Different from traditional hydraulic mode, the technical solution of the utility model replaces traditional liquid using fluid resin Pressure oil, can be to avoid corrosion of the hydraulic oil to oil pipe line.
, can also be by setting liquid on hydraulic cylinder using hydraulic package as the power source for driving upper and lower seal assembly Table is pressed, directly displays detection pressure.
Moreover, upper and lower seal assembly is driven using hydraulic way, compared with sledgehammer impact method of the prior art, gram Taken square defect subspaces it is narrow and small be not easy to very much personnel operation the defects of.
Brief description of the drawings
Fig. 1 show the structure diagram of the utility model.
Embodiment
The utility model is described further below in conjunction with attached drawing.
As shown in Figure 1 be the utility model structure diagram, 2 both ends of double male joint respectively with 8 screw thread of pipeline 1 and pipeline Connection.
2 both ends threaded connection place of double male joint leaks in order to prevent, is respectively arranged with lower seal assembly 4 and upper seal assembly 7, correspondingly, lower seal assembly 4 is provided with elastic seal ring 3, upper seal assembly 7 is provided with elastic seal ring 9.
Between lower seal assembly 4 and upper seal assembly 7 some hydraulic packages 5, this implementation are evenly equipped with along pipeline circumferencial direction In example, preferably 8 sets of hydraulic packages 5 are uniformly arranged.
Hydraulic package 5 includes outer cylinder sheath and inner cylinder liner, and inner cylinder liner back-off is arranged in outer cylinder sheath, inside and outside cylinder sleeve joint face On be provided with sealing ring 10.
It is provided with inlet on outer cylinder sheath casing wall, inlet is provided with injection device 6, and during work, fluid resin is passed through note To mould device 6 and inject hydraulic package 5, the lower seal assembly 4 of the driving of hydraulic package 5 and upper seal assembly 7 compress elastic seal ring 3 and 9, with Achieve the purpose that to seal anti-leak.
The mode of operation that tight or screwing screw holds out against is pounded compared to existing wedge, the utility model is using hydraulic package drive The mode of upper and lower seal assembly is moved, not only alleviates the labor intensity of site operation personnel, and injection pressure mechanism is compact-sized, It is very suitable for the constructing operation in the Fang Jing of narrow space, work efficiency can be effectively improved, reduce the time of constructing operation, also The instruments such as pressure gauge can be utilized, monitor the change of hydraulic pressure in real time, ensure sealing effect reliably and with long-term.
Fluid resin is injected hydraulic package 5 by the utility model using injection device, both be ensure that sealed reliable, be turn avoid It may cause the hidden danger of oil circuit pollution using normal hydraulic oil.
