Described downside is provided with at least 2 breach, and is provided with spacing between 2 described breach; 2 described breach are connected by the fluid passage be located in described Rotary-table.
In above-mentioned Sealing, the little bottom of described Rotary-table is connected with a wing plate, and described wing plate can be used for the rigidity strengthening described Sealing, and fixing when described Sealing is installed.
In above-mentioned Sealing, the two ends of described wing plate are provided with boss, and described boss can be used for the fixing of the seal, realize this function by coordinating perpendicular connectors main body.
In above-mentioned Sealing, described breach can be triangle.
In above-mentioned Sealing, the downside of described Rotary-table is provided with 4 described breach, and every 2 described breach are connected by fluid passage described in, and described breach can be used for carrying out sealing test with coordinating of described fluid passage.
In above-mentioned Sealing, every 2 described breach are symmetric centered by the axis of described Rotary-table.
In above-mentioned Sealing, described downside is provided with the draw-in groove of at least one annular, is provided with rubber ring in described draw-in groove, described rubber ring can be used for metallic sealing section lose seal action after secondary seal, and can be used for preventing external fluid from entering pipeline.
In above-mentioned Sealing, described downside is provided with 2 described draw-in grooves, and 2 described draw-in grooves are symmetric centered by the longitudinal axis of described Rotary-table.
In above-mentioned Sealing, described draw-in groove can be dovetail groove, and rubber ring can more firmly be fixed in described draw-in groove by described dovetail groove closely.
The present invention has following beneficial effect:
Sealing provided by the invention, wherein side tapering, breach and fluid passage the needs that can realize sealing test are set, enable the present invention realize sealing test function; Fluid channel structure in the present invention is simultaneously simple, is easy to manufacture, thus reduces manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of Sealing of the present invention.
Fig. 2 is the schematic diagram of Sealing of the present invention when sealing.
Schematic diagram when Fig. 3 is interference after Sealing of the present invention sealing.
In figure, each mark is as follows:
The sealing contact surface of 1 upper side, 2 downsides, 3 breach, 4 dovetail grooves, 5 internal protrusion, 6 wing plates, 7 times hub seats, 8 fluid passages, 9 Rotary-tables, 10 boss.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described, but the present invention is not limited to following examples.
As shown in Figure 1, Sealing provided by the invention comprises a cylindrical body (not marking in figure), and the periphery wall of this cylindrical body is provided with a Rotary-table 9, and the large bottom of this Rotary-table 9 is connected with cylindrical body.In the present invention, the side of Rotary-table 9 comprises the upper side 1 and downside 2 that are connected, and upper side 1 is near the large bottom of this Rotary-table 9, and the inclination of upper side 1 is less than the inclination of downside 2, as shown in Figure 3.
Downside 2 is provided with 4 breach 3 triangular in shape, when carrying out sealing test, as sealing test chamber, every 2 breach 3 are symmetric centered by the longitudinal axis of Rotary-table 9, and be provided with fluid passage 8 between every 2 symmetrically arranged breach 3, be communicated with 2 breach on downside, when carrying out sealing test, as the fluid passage of test.Because fluid passage 8 is close to Sealing inwall, internal protrusion 5 is provided to gain in strength.
Downside 2 is provided with 2 annular dovetail grooves 4, and these 2 dovetail grooves 4 are symmetric centered by the axis of Rotary-table 9.Be equipped with rubber ring in 2 dovetail grooves 4, play secondary seal effect and prevent outside seawater from entering, when carrying out sealing test, rubber ring 4 and upper side 1 form confined space, for the reliability that test seal is installed.
In the present invention, the little bottom of Rotary-table 9 is also connected with a wing plate 6, and the effect of wing plate 6 is spacing, prevents from executing carrying excessively.The two ends boss 10 of wing plate 6 is for strengthening Sealing rigidity, and fixing when Sealing is installed, and matching connector main body can realize this function.
Sealing installation process provided by the invention is as follows:
(1) on the sealing surface seal being placed in the lower end hub seat of underwater vertical connector (utilizing the fixing device that connector carries).
(2) under the effect of connector setting tool, moved down by upper end hub seat, the side of the Rotary-table of Sealing is touched with the hub seated connection of upper/lower terminal respectively, and now Sealing is in place.
(3) locking mechanism of connector starts action, and promote upper end hub seat and continue to move down, and produce axial compression to Sealing, Sealing (comprising rubber ring) produces micro-strain.
(4), after locking mechanism is locked completely, start to carry out sealing test.Sealing test liquid is injected in breach 3 by the passage on connector, and is full of upper and lower two breach 3(test cavity by the sealing test fluid passage 8 on Sealing).
(5), after test liquid reaches certain pressure, pressurize certain hour, checks whether the pressure drop higher than acceptable level.Check by rear, sealing installation, starts to withdraw setting tool.
Sealing provided by the invention needs after using certain hour to change, its Renewal process and installation process similar.
As shown in Figures 2 and 3, sealing contact and interference schematic diagram is respectively.Before seal preload applies, the upper side 1 of Sealing contacts with the sealing contact surface zero pressure of hub seat, as shown in Figure 3.Now, the inclination due to upper side 1 is less than the inclination of downside, therefore only has the upper side 1 of Sealing to contact with the sealing contact surface of hub seat.After starting imposed load, top hub seat starts to move down, and Sealing two ends produce radial deformation, produce radial spring-back force and circumferential pressure simultaneously.The part that rubber ring exceeds metal is compressed, and forms temporary sealing.Due to the effect of wing plate, the displacement of top hub seat is limited in the scope that sets, and therefore the two ends of Sealing can not produce excessive radial distortion, seals the two end part that contact range is still confined to Sealing simultaneously.Now the position of hub seat as shown in Figure 3, and wing plate has contacted completely with hub seat and born unnecessary pretightening force.Compared with before distortion, Sealing two ends radial compression, and its spring-back force bears hub seat sealing load.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
