Abstract
The utility model relates to a sealing technique under the deep water pressure environment of full sea, specifically speaking are sealing device under the super high water pressure environment. The test cylinder is arranged between a connector transition sleeve of the test cylinder for the myriameter hydrostatic test and a test cylinder end cover, and adopts a structure of a small-space O-shaped groove and an O-shaped rubber sealing ring; the method specifically comprises the following steps: one end of the transition sleeve is provided with a 90-degree two-side open ring groove, and an O-shaped ring is arranged in the groove. After the end cover is assembled on the end cover of the test cylinder, a small-space sealing ring groove is formed with the end cover, and sealing in two directions of the end face and the radial direction is realized. The utility model discloses can cover full sea depth, sealing performance is reliable. The structural design is novel and compact; the use is safe and reliable.
Description
Technical field
The utility model relates to the sealing technique under the complete extra large deep water downforce environment, the seal arrangement under specifically a kind of ultra high water pressure environment.
Background technique
At present, pressure experimental device under the pressure environment mostly is rubber seal sealing under water, the Bolt Connection fastening structure, and high test pressures is 75MPa, Maximum operating pressure is 72MPa, and connecting by a plurality of bolts of manually tightening circumference between end cap and the test tube cylindrical shell realizes.Metal o-ring is adopted in high pressure in the past and the sealing under the ultra-high voltage environment more.Metal o-ring not only costs an arm and a leg, and not reproducible use, and promptly metal o-ring is owing to its expendable plastic deformation, disposable only use.
The model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides that a kind of energy is nonexpondable, the seal arrangement under the reliable ultra high water pressure environment of sealability, and it is specially adapted to the myriametre hydrostatic testing machine.
To achieve these goals, technical solutions of the utility model are: be installed between the connector assembly spacer shell and test tube end cap of the myriametre hydrostatic test with the test tube, adopt little space " O " groove to add " O " type rubber seal coil structures; Be specially: at an end that excessively overlaps, have the open annular groove in-90 ° of two sides, lay " O " circle in the groove.After being assemblied on the test tube end cap,, and realize end face and the radially sealing of both direction with the little space sealing annular groove of its formation.
The utlity model has following characteristics:
1. can be used for simulating in the testing apparatus in complete extra large deep water pressure ring border.Adopt the utility model technology, high test pressures is 120MPa, and Maximum operating pressure can reach 110MPa, is applicable to that full sea is dark.The underwater electrical connector that it can be used for the different depth of waters (the darkest ten thousand metres under water that reach) grade carries out corresponding pressure test, with verify its structural strength, sealability and in working order under electrical properties etc.
2. good seal performance.The present invention utilizes combination little space " O " groove to add the sealing means of " O " type rubber seal, has solved the sealing problem between connector assembly and the test tube end cap, can realize end face and the radially sealing of both direction.Belong to sealing (the reaching 120Mpa) technology under the ultra high water pressure.
3. structural design novelty of the present invention, compactness; Safe in utilization, reliable.
Description of drawings
Fig. 1 is one embodiment of the invention test tube (containing two end cap) structural drawing.
The sealing device structure figure of Fig. 2 for amplifying between connector assembly among Fig. 1 and the test tube end cap.
Embodiment
Shown in Fig. 1-2, be installed between the connector assembly and test tube end cap on the myriametre hydrostatic test tube 4, be specially: at an end that excessively overlaps 7, have the open annular groove in-90 ° of two sides, lay " O " rubber seal 31 in the groove.After being assemblied on the test tube end cap,, at end face and radially be tightly connected between both direction and connector assembly spacer shell and the test tube end cap, realize that end face reaches the radially sealing of both direction with the little space sealing annular groove of its formation.3 for connecting locating stud.
Above-mentioned sealing belongs to sealing (the reaching 120Mpa) technology under the ultra high water pressure, does not see application in the past.Facts have proved, above-mentioned two kinds of sealing configurations, not only simple in structure, be easy to processing, and good sealing effect, and reusable.Compare with metal o-ring, user cost reduces greatly.
Claims (1)
1. the seal arrangement under the ultra high water pressure environment is characterized in that: be installed in the myriametre hydrostatic test with between the connector assembly spacer shell of test tube and the test tube end cap, employing " O " groove adds " O " type rubber seal coil structures; Be specially: at an excessive end of cover (7), have the open annular groove in one 90 ° of two sides, lay " O " circle in the groove, at end face and radially be tightly connected between both direction and a connector assembly spacer shell and the test end cap.
