Description
Technical field
The present invention relates to the pressure experimental device of complete extra large deep water downforce environment, specifically a kind of myriametre water test unit.
Background technology
At present, pressure experimental device under the pressure environment mostly is rubber seal sealing under water, the bolted on connection fastening structure, and high test pressures is 75MPa, maximum working pressure (MOP) is 72MPa, and the connection between end cap and the test tube cylindrical shell is realized by a plurality of bolts of manually tightening circumference.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 because its expendable plastic yield, disposable only use, and the pressure experimental device that can simulate complete extra large deep water downforce environment does not also still have report in China.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this invention is to provide and a kind ofly can contain that full sea is dark, the reliable myriametre water test unit of sealing property.
To achieve these goals, technical solution of the present invention is: be made up of longeron, sealed cylinder, end cap, test tube etc., wherein: described longeron is can rotating Γ type, and the bottom and the support of Γ type are hinged, and the position, intermediate portion is connected with fluid power system; Sealed cylinder and longeron are installed together, and the test tube is rack-mount, between sealed cylinder, is equipped with end cap;
Described end cap and hydraulic pressure system join by spacer shell; Described test tube is installed together by fixed pin with end cap; Hermetically-sealed construction between described test tube and the end cap is: have a seal groove on end cap, be disposed with sealing copper ring and " O " type rubber seal in seal groove, leave the space in " O " type rubber seal outside; Is arcwall face at the sealing copper ring with the contacted surface of contact of " O " type rubber seal; Hermetically-sealed construction between described connector and the test tube end cap is: have a seal groove being installed on excessively putting of test tube, be embedded with " O " type rubber seal at seal groove.
The present invention has following characteristics:
1. can be used for simulating complete extra large deep water pressure ring border.Adopt the technology of the present invention, high test pressures is 120MPa, and maximum working pressure (MOP) can reach 110MPa, and it is dark to contain full sea.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, sealing property and in working order under electric property etc.Domestic still do not have the testing equipment that this ultra high water pressure can be provided at present.
2. adopt brand-new test tube cylindrical shell and the automatic encapsulation technology of end cap of the present invention, the whole process of suppressing need not turning of any bolt can be carried out, and encapsulation is reliable, accurate, quick, has shortened greatly and has suppressed the working time.The present invention provides new technology path for the application on the related pressure testing apparatus.
3. 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 and the test tube end cap; Utilize swing-in seal groove sealing copper ring and the sealing means that " O " type rubber seal makes up, solved the sealing problem between end cap and the test tube cylindrical shell.The sealing at above-mentioned two places all belongs to sealing (the reaching 120Mpa) technology under the ultra high water pressure.
4. structural design novelty of the present invention, compactness; Safe in utilization, reliable.

Fig. 2 is the side view of Fig. 1.
Fig. 3 tests tube (containing two end cap) structural drawing for the present invention.
The sealing device structure figure of Fig. 4-1 for amplifying between end cap among Fig. 3 and the test tube cylindrical shell.
The sealing device structure figure of Fig. 4-2 for amplifying between connector among Fig. 3 and the test tube end cap.
Embodiment
Shown in Fig. 1～3, the myriametre water test unit, it is made up of longeron 1, sealed cylinder 2, end cap 3, test tube 4 etc., wherein: described longeron 1 is can rotating Γ type, the bottom of Γ type and support 5 are hinged, middle part be connected with the oil pressure actuated system (comprise and drive oil cylinder, Hydraulic Station and oil pressure gauge); Sealed cylinder 2 is installed together with longeron 1, and test tube 4 is installed on the support 5, between two sealed cylinders 2, is equipped with end cap 3, and end cap 3 joins by spacer shell 7 with hydraulic pressure system (comprising pressure pump and water pressure gauge).End cap 3 is fixed on test tube 4 two ends by fixed pin 8.
Be the hermetically-sealed construction between test tube 4 and the end cap 3 as Fig. 4-1, the myriametre hydraulic testing with test tube 4 adopt be swing-in seal groove sealing copper ring and the sealing means realization of " O " type rubber seal combination seals; Promptly on end cap 3, have a seal groove, in seal groove, be disposed with sealing copper ring 31 and " O " type rubber seal 32, leaving the space in " O " type rubber seal 32 outsides, is arcwall face at sealing copper ring 31 with " O " type rubber seal 32 contacted surface of contact.
As Fig. 4-2 is hermetically-sealed construction between connector and the test tube end cap, and the myriametre hydraulic testing adopts combination little space " O " grooves to add the sealing means of " O " type rubber seal with test tube 4, realizes sealing.On the spacer shell 7 that is installed on test tube 4, have a seal groove, be embedded with " O " type rubber seal 32 at seal groove.
The sealing at above-mentioned two places all 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 hermetically-sealed constructions, not only simple in structure, be easy to processing, and good sealing effect, and reusable.Compare with metal o-ring, use cost reduces greatly.
The course of work of the present invention is as follows:
When not suppressing, longeron 1 can be in open configuration; When suppressing, earlier the connector of desiring to suppress (or other parts) is contained on the end cap 3 at test tube 4 two ends, and end cap 3 is contained in test tube 4 two ends, fixing with fixed pin 8, then under the effect that drives oil cylinder 6, with longeron 1 and on sealed cylinder 2 pendulum be back to and suppress position (sealed cylinder 2 aligns with the central axis of test tube 4).The piston motion of sealed cylinder 2 is test tube 4 sealing stations (being that piston end surface and end cap 3 end faces are to closing) extremely, and will test an interior fills with water.After above-mentioned steps is finished, just can carry out bulge test by the pressurization program.Suppress finish after, press the decompression program release, operation steps is opposite when suppressing.
This device is underwater units such as underwater robot and equipment with development, the test of the underwater electrical connector equipment indispensable with production.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, sealing property and in working order under electric property etc.
