The invention relates to a sealing ring sealing device which is used for sealing a plastic part (8) and other parts (11); the plastic part (8) is provided with an accommodating groove (9) and a gas exhausting channel (10); and the sealing ring sealing device comprises a rubber sealing ring (1) which is positioned in the accommodating groove (9) and matched with the accommodating groove (9) in dimension, a metal guide tube (7), a metal framework (6) and the gas exhausting channel (10). The lower part of the rubber sealing ring (1) is provided with a groove (4); two bosses (3) are arranged at the two sides of the rubber sealing ring (1); a gas exhausting space is formed between the upper part of the rubber sealing ring (1) and the inner wall of the accommodating groove (9); a gas guide hole (5) is formed in the rubber sealing ring (1); the metal guide tube (7) is placed in the gas guide hole (5); and the metal framework (6) is placed in the groove (4). The sealing ring sealing device modifies the original plastic part a little, can obviously prevent the sealing ring from being deformed, and is good in sealing performance.
Description
Technical field
The present invention relates to a kind of seal ring seal arrangement, particularly relate to being tightly connected of engine body and periphery case class plastic items.
Background technique
In the connection of case class working of plastics and engine body, generally by rectangle or " O " RunddichtringO as in the groove in case class working of plastics, the extruding force applied by bolt realizes the sealing of connection part.But in the connection of working of plastics and body, due to reasons such as pretightening force are large, body vibration is large, potted line is long, seal ring easily deforms and poor sealing performance, the problems such as leakage are caused to produce.
At present, generally this kind of problem is improved by improving the methods such as ring structure, improvement sealing ring material, increase seal ring number.But in actual use, increase seal ring number and groove number corresponding in plastic items also will be increased, larger to the change of original plastic items; And for sealing ring material and architecture advances, although achieve certain effect at present, effect is unsatisfactory.
Summary of the invention
The object of the invention is the deficiency in order to overcome above-mentioned background technology, providing a kind of structure simple, change less to original working of plastics and can obviously prevent sealed ring deformation, increase the service life, improving sealing, prevent the seal ring seal arrangement of seepage.
In order to realize above object, the invention provides a kind of seal ring seal arrangement, for the sealing between working of plastics 8 and miscellaneous part 11, working of plastics 8 offers containing groove 9 and bleed-off passage 10, one end of bleed-off passage 10 is connected with outside, and one section is connected with the top of containing groove 9, and described seal ring seal arrangement comprises and is positioned at containing groove 9 and the rubber seal 1, metal catheter 7, metal frame 6 and the bleed-off passage 10 that match with its size, wherein
The bottom of described rubber seal 1 offers groove 4, and the both sides of the groove 4 of bottom are two boss 3, leave air extraction space between the top of rubber seal 1 and containing groove 9 inwall; In rubber seal 1, offer gas port 5, the number of gas port 5 is determined according to seal ring length, is placed with metal catheter 7 in gas port 5; In the groove 4 of described rubber seal 1 bottom, be placed with metal frame 6, one end of metal catheter 7 is connected with air extraction space, and the space that the other end surrounds with metal frame 6 is connected.
Wherein, metal frame can be made up of wire netting, has certain rigidity; Match with the groove 4 of described rubber seal 1 bottom.
Metal catheter and rectangular metal skeleton when mounted, are placed in the air guide channel in rubber seal and bottom groove by the present invention; Again whole assembly is placed in the containing groove of working of plastics, utilizes bolt to be arranged in body.Realize sealing first by extruding force; Finally by bleed-off passage, sealing ring lower potion groove and top residual space are vacuumized with vaccum-pumping equipment, realize secondary seal by vacuum environment.
Wherein, the arcuate structure at the upper end trapezium structure of rubber seal and the upper and lower two ends of boss builds multiple-sealed when extruding, and contributes to sealing; Rectangular metal skeleton plays a supportive role to rubber seal, effectively can prevent the distortion of rubber ring under vacuum environment and ambient pressure; Metal catheter plays a supportive role to gas port, effectively can prevent the connection of gas port under vacuum environment and ambient pressure; Sealing ring lower potion groove and top residual space are vacuumized and can be strengthened the sealing of seal arrangement.
The present invention is compared with the prior art, and fully its superiority of display is: change less to original working of plastics, obviously can prevent sealed ring deformation, good seal performance.
Accompanying drawing explanation
Fig. 1 is the schematic three dimensional views of the rubber seal segment in the present invention
Fig. 2 is the schematic cross-section of apparatus of the present invention
Concrete implementing measure
Below in conjunction with accompanying drawing, sealing ring seal device is described in further details.
The schematic three dimensional views of the rubber seal segment in Fig. 1 the present invention, Fig. 2 is the schematic cross-section of apparatus of the present invention.
Sealing ring seal device is used for the sealing between working of plastics 8 and body 11, comprises rubber seal 1, metal catheter 7, rectangular metal skeleton 6, the containing groove 9 corresponding with rubber ring and bleed-off passage 10.
Top, rubber seal 1 cross section is trapezoidal 2, and trapezoidal gradient is 15 ° ~ 20 °; Two ends, left and right, bottom are two boss 3, and boss upper and lower surface is curved, form rectangular recess 4 between two boss; Gas port 5 containing air guide in rubber seal.Metal catheter 7 and above-mentioned gas port 5 match, and conduit number is corresponding with gas port.
Rectangular metal skeleton 6 is made up of wire netting, has certain rigidity; Match with above-mentioned groove 9.Containing groove 9 is arranged in the working of plastics that will install, and upper end, cross section is trapezoidal, wants to mate but trapezoidal higher than in rubber seal of height with rubber seal; Lower end, cross section is rectangular, and for placing boss 3 and the groove 4 of rubber ring, rectangular elevation is lower than boss 3 height, and width is greater than boss 3 and groove 4 entire length, leaves certain interval.Bleed-off passage 10 is arranged in the working of plastics of installation, and one end is connected with containing groove top, and one end is connected with vaccum-pumping equipment.
During installation, metal catheter 7 and rectangular metal skeleton 6 are placed in the gas port 5 in rubber seal 1 and bottom groove 4; Again whole assembly is placed in the containing groove 9 of working of plastics, utilizes bolt to be arranged in body 11, realize sealing first by extruding force; Finally by bleed-off passage 10, sealing ring lower potion groove 4 and top residual space are vacuumized with vaccum-pumping equipment, realize secondary seal by vacuum environment.Wherein, the upper end trapezium structure 2 of rubber seal and the arcuate structure at boss about 3 two ends build multiple-sealed when extruding, and contribute to sealing; Rectangular metal skeleton 6 pairs of rubber seal 1 play a supportive role, and effectively can prevent the distortion of rubber ring 1 under vacuum environment and ambient pressure; Metal catheter 7 pairs of gas ports 5 play a supportive role, and effectively can prevent the distortion of gas port 5 under vacuum environment and ambient pressure; Sealing ring lower potion groove 4 and top residual space are vacuumized and can be strengthened the sealing of seal arrangement.
