Accompanying drawing explanation
Fig. 1 is the sectional drawing of the utility model Sealing.
Fig. 2 is the schematic diagram of the utility model Sealing while sealing.
Schematic diagram when Fig. 3 is the rear interference of the utility model Sealing 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 utility model is further illustrated, but the utility model is not limited to following examples.
As depicted in figs. 1 and 2, the Sealing that the utility model provides comprises a cylindrical body (not marking in figure), be provided with a Rotary-table 9, and the large bottom of this Rotary-table 9 is connected on the periphery wall of this cylindrical body with cylindrical body.In the utility model, the side of Rotary-table 9 comprises upper side 1 and the downside 2 being 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.
On downside 2, be provided with 4 breach triangular in shape 3, 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 a 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.Due to fluid passage 8 from Sealing inwall close to, internal protrusion 5 is provided to gain in strength.
On downside 2, be provided with 2 annular dovetail grooves 4, these 2 dovetail grooves 4 are symmetric centered by the axis of Rotary-table 9.In 2 dovetail grooves 4, be equipped with rubber ring, play secondary seal effect and prevent that outside seawater from entering, when carrying out sealing test, rubber ring 4 and upper side 1 form confined space, the reliability of installing for test seal.
In the utility model, 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 can matching connector main body realize this function.
The Sealing installation process that the utility model provides is as follows:
(1) seal is placed on the sealing surface of lower end hub seat of the vertical connector of deep water (fixing device of utilizing connector to carry).
(2) under the effect of connector setting tool, upper end hub seat is moved down, the side of the Rotary-table of Sealing is touched with the hub seated connection of upper/lower terminal respectively, now Sealing is in place.
(3) locking mechanism of connector starts action, promotes upper end hub seat and continues to move down, and Sealing is produced to axial compression, and 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) test liquid reaches after certain pressure, and pressurize certain hour checks and whether has the pressure drop higher than acceptable level.After inspection is passed through, sealing installation, starts to withdraw setting tool.
The Sealing that the utility model provides needs to change after using certain hour, and its Renewal process and installation process are similar.
As shown in Figures 2 and 3, be respectively sealing contact and interference schematic diagram.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, because the inclination of upper side 1 is less than the inclination of downside, so only there is the upper side 1 of Sealing to contact with the sealing contact surface of hub seat.Start after imposed load, top hub seat starts to move down, and Sealing two ends produce radial deformation, produce radially spring-back force and circumferential pressure simultaneously.It is compressed that rubber ring exceeds the part of metal, forms temporary sealing.Due to the effect of wing plate, the displacement of top hub seat is limited in the scope setting, so 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 as shown in Figure 3, wing plate has contacted and has born unnecessary pretightening force completely with hub seat in the position of hub seat.With before distortion, compare, 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 utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
