Abstract
The utility model relates to a high pressure vessel perforation sealing member, including seal face, seal and sealed bottom surface, it is corrugated that the overall structure of seal is the tubulose, the seal is hollow structure, vertically is provided with multiunit arcuation fold on the seal side by side, seal face and sealed bottom surface set up respectively in the upper and lower port department of seal. The seal face be the end face seal ring sealed with high -pressure pipe interference, sealed bottom surface includes the cyclic annular clamp plate of rigidity, evenly offers a plurality of screws at the cyclic annular clamp plate of rigidity. The utility model discloses the compressing deformation that utilizes corrugated seal compensates the vibrations and the skew of pipeline, plays protection of high -pressure vessel perforation position and sealed effect.
Description
Technical field
The utility model belongs to aircraft air supply system technical field of sealing technology, particularly a kind of high-pressure conduit aperture seal part, and the utility model is applicable to protection and the sealing of the vessel perforation of aircraft air supply system.
Background technique
Aircraft air supply system high-pressure conduit operationally internal gas maximum temperature can reach 260 DEG C, during work, vibrations and displacement are 10mm to the maximum, conduit extends to aircraft exterior, catheter interior is even has liquid to spray, internal body is entered by the perforation of body for preventing the liquid in pipeline and rainwater, increase high-pressure conduit aperture seal part to play seal action, the operational safety of aircraft is promoted, urgently designs a effective Sealing.
Summary of the invention
For solving the technical problem of existing existence, the purpose of this utility model is to provide a kind of high-pressure conduit aperture seal part, solves protection and the seal request of current aircraft air supply system high-pressure conduit site of perforation.
For achieving the above object, the technical solution of the utility model is:
A kind of high-pressure conduit aperture seal part, comprises seal face, seal and sealing bottom surface; The overall structure of described seal is corrugated in a tubular form; Seal is hollow structure, and seal is longitudinally set side by side with many group arcuation folds; Seal face and sealing bottom surface are arranged at the upper and lower port of seal respectively.
Described seal face is the end face sealing ring with high-pressure conduit interference seal; Sealing bottom surface comprises rigid annular pressing plate, and multiple screw evenly offered by rigid annular pressing plate.
The beneficial effects of the utility model are:
1. the utility model utilizes the compressive strain of corrugated seal to compensate the vibrations of pipeline and skew, plays the effect to the protection of high-pressure conduit site of perforation and sealing;
2. the utility model takes into account the requirement of the performances such as intensity, fire-retardant and anti-damp and hot, mould, salt fog, meets flight usage requirement.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the worm's eye view of Fig. 1;
Fig. 3 is longitudinal sectional view of the present utility model;
Fig. 4 is using state schematic diagram of the present utility model;
In figure, 1-seal face, 2-seal, 3-seals bottom surface.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further detailed, a kind of high-pressure conduit aperture seal part as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprises seal face 1, seal 2 and sealing bottom surface 3; The overall structure of described seal 2 is corrugated in a tubular form; Seal 2 is hollow structure, and seal 2 is longitudinally set side by side with many group arcuation folds; Seal face 1 and sealing bottom surface 3 are arranged at the upper and lower port of seal 2 respectively.
Seal face 1 is the end face sealing ring with high-pressure conduit interference seal; Sealing bottom surface 3 comprises rigid annular pressing plate, and multiple screw evenly offered by rigid annular pressing plate.
The fluorosioloxane rubber material that high-pressure conduit aperture seal part main body of the present utility model is 50 degree by hardness rank is made, high-pressure conduit aperture seal part is fixedly mounted on aircraft air supply system high-pressure conduit site of perforation, when high-pressure conduit is through high-pressure conduit aperture seal part, by the interference fit of seal face 1 with high-pressure conduit, rainwater and liquid outside aircraft is stoped to flow into internal body, because high-pressure conduit during flight exists vibrations and displacement, by the compressible of seal 2 with stretching structure characteristic can come vibrations and the displacement of compensation conduit, the part of sealing bottom surface 3 is connected with airframe by bolt, realize the fastening of Sealing, as shown in Figure 3.By the flight seal request that seal face 1 and the two-part acting in conjunction of seal 2 are bored a hole to ensure high-pressure conduit.
Because high-pressure conduit inside is high-temperature gas, conduit has aircraft runoffs splash simultaneously, for ensureing that Sealing can meet all kinds of environmental requirement under flying condition and resistant to liquid performance, select fluorosioloxane rubber as high-pressure conduit aperture seal part material of main part formula, the high-pressure conduit aperture seal part that the resistance to environment produced, medium-resistance are superior.
Research and development of the present utility model are protection for solving current ARJ21-700 aircraft air supply system high-pressure conduit site of perforation and seal request.Analog structure product is both at home and abroad at present all without application example, research staff is according to the concrete service condition of ARJ21-700 aircraft air supply system high-pressure conduit site of perforation, according to flight environment and park actual demand, consider the impact of the various weather in high low latitude, the performance reliability under typical environmental conditions is run into during in order to ensure that product works aboard, the working environment pressure requiring ARJ21-700 aircraft air supply system high-pressure conduit aperture seal part product performance satisfied is at-1700ft ~ 39000ft, and ambient temperature range is-55 DEG C ~+260 DEG C.And design high-pressure conduit aperture seal part can meet the amount of deformation that all directions are not more than 10mm, to compensate contingent pressure duct displacement in-flight.Realize the protection of ARJ21-700 aircraft air supply system high-pressure conduit perforated portion and sealing effect.
For ensureing that Sealing product can meet the oil-water media of all kinds of environmental requirement under flying condition and contact, hardness rank is selected to be that the fluorosioloxane rubber of 50 degree is as material of main part, under the prerequisite of physical and mechanical properties not affecting fluorosioloxane rubber material, make it take into account the requirement of the performances such as intensity, fire-retardant and anti-damp and hot, mould, salt fog through formula adjustment, meet usage requirement of flying.Test through stand test and installation installation, respond well; The specific performance index that Products Institute will reach is as shown in table 1, table 2.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model specification to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
