Abstract

The utility model discloses a setting device for detection pressurization of gas tightness of a casing pipe. The setting device comprises a piston-type sliding sleeve, a first hard ring, a setting rubber cylinder, a second hard ring, a first cone ring, a pressure energy storage ring and a second cone ring, wherein the piston-type sliding sleeve, the first hard ring, the setting rubber cylinder, the second hard ring, the first cone ring, the pressure energy storage ring and the second cone ring are sleeved on a pipe body in sequence, the piston-type sliding sleeve slides axially under driving by high pressure gas, and a cap which is in threaded connection with the pipe body and is axially located is arranged on one side of the second cone ring. The setting device for the detection pressurization achieves quick setting and deblocking when the gas tightness of the casing pipe is detected.

Description

The sleeve pipe tightness detects the seating and sealing unit of pressurization
Technical field
The utility model relates to the package seal checker field of the screw thread of the connecting portion in pipeline, and specifically a kind of sleeve pipe tightness detects the seating and sealing unit of pressurization.
Background technology
Be parts commonly used at oil gas field manufacturing process middle sleeve.Need to connect into the conveying that feed-line is completed oil, gas with pipe fittings such as sleeve pipe and aids thereof.In use need sleeve pipe to keep good tightness, and the tightness problem easily occurs at the threaded joints of sleeve pipe.Therefore, usually need the screw connection point of these sleeve pipes is carried out sealing propertytest, or the screw thread of the sleeve pipe after repairing is repaired the position carry out the tightness detection.
The way of tightness effect that detects the screw thread of sleeve pipe in prior art is: in the laboratory the pin thread of sleeve pipe and box, the box of being connected with standard respectively is connected with male joint, set up confined space, then inject a certain amount of high pressure detection gas in confined space, the detected pipe fitting of water submergence again, detected pipe fitting does not emit bubble within a certain period of time, illustrates that the sealing of detected pipe fitting reaches requirement.Detect qualified after, the more detected pipe fittings such as sleeve pipe are unloaded from joint, be transported to respectively the job site and use.And above-mentioned prior art can not realize in the oil gas field job site.The one, increased cost of transportation, the tightness after can not detecting it and connect for the sleeve pipe that connects at the scene or aid in addition.The utility model designer has researched and developed and a kind ofly can be at the scene carry out to sleeve pipe the instrument that tightness detects for this reason, the focusing on of this instrument arranges two relative seating and sealing units on a body, form airtight annular space so that the both sides that wish detects the position in sleeve pipe set.And existing seating and sealing unit is not suitable for using in this instrument.
Problem and defective in view of the existence in the sleeve pipe tightness detects of above-mentioned existing seating and sealing unit, the utility model designer relies on for many years working experience and abundant professional knowledge are actively studied and innovate, finally develop the seating and sealing unit that a kind of sleeve pipe tightness detects pressurization, set fast and deblocking when the sleeve pipe tightness is detected with realization.
The utility model content
In order to solve the above-mentioned problems in the prior art, the seating and sealing unit that the utility model provides a kind of sleeve pipe tightness to detect pressurization sets and deblocking when the sleeve pipe tightness is detected fast with realization.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
The sleeve pipe tightness detects the seating and sealing unit of pressurization, comprise: be sheathed on successively on body be subjected to drive of high-pressure gas and in axial sliding piston type sliding sleeve, first encircle firmly, set that packing element, second encircles firmly, the first conical ring, pressure accumulation of energy ring and the second conical ring, a side of the second conical ring also is provided with the axial location that is threaded with body and cap.
Further, described pressure accumulation of energy ring comprises annular body and elastic ring, wherein annular body axially is divided at least three lobes, has circumferential annular groove on the outer wall of annular body, described elastic ring is located in annular groove, and the both ends of the surface of described annular body are the inclined-plane that matches with the conical surface of described the first conical ring and the second conical ring respectively of indent.
Further, described annular body is divided into pintongs vertically.
Further, described annular body is made of metal.
Further, described elastic ring is rubber ring.
Compared with prior art, the beneficial effects of the utility model are:
Seating and sealing unit of the present utility model sets packing element by the extruding of gases at high pressure pushing piston formula sliding sleeve, due to and the location of cap, make the packing element that sets that is oppositely arranged expand and set respectively on the internal surface of sleeve pipe of both sides, detected position, set at two and form airtight annular space between packing element; Simultaneously, pressure accumulation of energy ring is subject to axial compression, and the inclined-plane of the end of pressure accumulation of energy ring is converted into radial load with axial force, pressure accumulation of energy ring storage power, when setting the packing element deblocking, the Conversion of Energy that pressure accumulation of energy ring stores is axial power, assists to set the quick deblocking of packing element.
Description of drawings
Fig. 1 is that the decomposition texture of the seating and sealing unit of sleeve pipe tightness detection pressurization of the present utility model cuts open figure;
Fig. 2 is the end face structure figure of preferred embodiment of the pressure accumulation of energy ring of the sleeve pipe tightness of the present utility model seating and sealing unit that detects pressurization.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Fig. 1 is that the decomposition texture of the seating and sealing unit of sleeve pipe tightness detection pressurization of the present utility model cuts open figure; Fig. 2 is the end face structure figure of preferred embodiment of the pressure accumulation of energy ring of the sleeve pipe tightness of the present utility model seating and sealing unit that detects pressurization.As depicted in figs. 1 and 2, the sleeve pipe tightness detects the seating and sealing unit of pressurization, comprise: be sheathed on successively on body be subjected to drive of high-pressure gas and in axial sliding piston type sliding sleeve 1, the first hard ring 2, the side that sets packing element 3, second hard ring the 4, first conical ring 5, pressure accumulation of energy ring 6 and the second conical ring 7, the second conical rings 7 also be provided with the axial location that is threaded with body and cap 8.
