Abstract
The utility model discloses a pressure buffering device of an underwater sealing mechanism. The pressure buffering device is used for buffering and balancing the pressure inside the sealing mechanism and comprises a cushioning disc, a buffering piece and a pressing device, wherein the buffering piece is connected with the cushioning disc, and the pressing device is connected with the buffering piece. The pressure buffering device is connected with the sealing mechanism, and a communicated sealing cavity is formed by the pressure buffering device and the sealing mechanism. The pressure buffering device is totally closed, and is small in size, good in durability, large in borne water pressure and convenient to install.
Description
Technical field
The utility model relates to a kind of pressure buffer device, specifically, relates to a kind of pressure buffer device for underwater sealing mechanism.
Background technique
Along with the ocean development activity is more and more frequent and deep, the marine oil and gas exploration that the mankind carry out and exploitation, ocean expedition, ocean engineering, submerged pipeline, cable lay exploitation with maintenance, ocean mineral etc., need to use underwater kit of all kinds, and all underwater kits have all configured seal arrangement, as sealing to electronic device, driver part and power supply etc., in order to strengthen the anti-pressure ability of seal casinghousing to deep-sea, usually fill sealing oil in seal arrangement.
But, change hugely from air to the deep-sea base pressure, the external and internal pressure that existing seal arrangement can not the balance underwater kit, cause the seal arrangement of underwater installation often by huge compression shock, shortened the working life of seal arrangement, so that the working life of having reduced whole underwater installation.
The model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of can reduce artificial delaying, and reduces costs the pressure buffer device of enhancing productivity.
For achieving the above object, the technical solution of the utility model is as follows: the pressure buffer device of a kind of underwater sealing mechanism, the pressure that is used for buffering and balance sealing mechanism inside, described pressure buffer device comprise the shock absorber of disc, the described disc of connection, the hold down gag of the described shock absorber of connection; Described pressure buffer device connects described sealing mechanism and with described sealing mechanism, forms the sealed chamber that communicates.
Further, described pressure buffer device also comprises Sealing, and described Sealing is arranged between described disc and described shock absorber.
Further, the junction surface of described disc and described shock absorber is provided with the groove that is complementary with described Sealing.
Further, described shock absorber is leather bag.
Further, described leather bag cross section is half elliptic.
Further, also be provided with the first through hole on described disc.
Further, described hold down gag is provided with the second through hole, and described the second through hole is at least 1.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is: the pressure buffer device of a kind of underwater sealing mechanism, the Underwater Pressure damping device keeps the seal arrangement inside and outside to have identical pressure, makes the seal arrangement body have good withstand voltage properties; The setting of Sealing and shock absorber simultaneously, make disc and press cover clamp sealing and pressure is cushioned, and reaches good sealing effect.
Description of drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment technology, below will the accompanying drawing of required use in embodiment's technical description be briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Wherein, 1, disc, the 11, first through hole, 2, shock absorber, 3, hold down gag, the 31, second through hole, 4, sealing mechanism, 5, Sealing.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment who obtains, and all belong to the scope of the utility model protection.
Embodiment 1
As shown in Figure 1 and Figure 2, the pressure buffer device of a kind of underwater sealing mechanism, be used for the pressure of buffering and balance sealing mechanism 4 inside, and pressure buffer device comprises disc 1, connects the shock absorber 2 of disc 1, the hold down gag 3 of connection shock absorber 2; Pressure buffer device connects sealing mechanism 4 and with sealing mechanism 4, forms the sealed chamber that communicates.
Pressure buffer device also comprises Sealing 5, and Sealing 5 is arranged between disc 1 and shock absorber 2, the preferred O type circle of Sealing 5; The junction surface of disc 1 and shock absorber 2 is provided with the groove that is complementary with Sealing 5 Sealing 5 is installed; The preferred leather bag of shock absorber 2; Also be provided with the first through hole 11 on disc 1, with sealing mechanism 4, form the sealed chamber that communicates.Hold down gag 3 is provided with the second through hole 31, is used for the external and internal pressure of balanced seal mechanism 4, and the second through hole 31 is at least 3.
All the other are same as the previously described embodiments, and difference is, the leather bag cross section is half elliptic, and leather bag can be one deck, also can be set to multilayer.
below introduce working principle of the present utility model: pressure buffer device is applied under water sealing mechanism, owing to being provided with the second through hole 31 on hold down gag 3, simultaneously, be provided with the first through hole 11 on disc 1, and with sealing mechanism 4, form the sealed chamber's (namely being equal to connecting vessels) that communicates, when pressure buffer device is positioned under water, the leather bag of pressure compressing under water, simultaneously, pressure in sealing mechanism 4 is also at the extruding leather bag, due to pressure action, leather bag can be out of shape left and right, until sealing mechanism internal and external pressure balance, avoided the compression shock in sealing mechanism 4 external worlds, thereby reach the effect of buffering and balance pressure.
Pass through technique scheme, the beneficial effect of technical solutions of the utility model is: the pressure buffer device of a kind of underwater sealing mechanism, the Underwater Pressure damping device keeps the seal arrangement inside and outside to have identical pressure, makes the seal arrangement body have good withstand voltage properties; The setting of Sealing and shock absorber simultaneously, make disc and press cover clamp sealing and pressure is cushioned, and reaches good sealing effect.
, to the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
