Abstract
The invention relates to a layer-merged sealing structure of a separator. The layer-merged sealing structure comprises a sealing member arranged between an end cover and a separator body, wherein the sealing element comprises sealing rings which are symmetrically arranged; a middle flange and side flanges are arranged on a contacted surface between each sealing ring and the end cover; the side flanges are symmetrically arranged at two sides of the corresponding middle flange and are in tight contact with the end cover; a deformation gap is reserved between each middle flange and the end cover; a groove is formed in the inner side of each sealing ring; a spring and a gasket are arranged in each groove; each gasket is in contacted with the bottom of the corresponding groove; and the end part of each spring is in contacted connection with the separator. According to the layer-merged sealing structure disclosed by the invention, by adopting a layer-merged sealing ring structure, dual-layer sealing between the end cover and the separator body is realized, and a good sealing effect is realized; and the sealing rings are provided with the deformation gaps and spring buffer structures, so that the condition that a sealing effect is lost due to hard extrusion is prevented, and the reliability in use is improved.
Description
Technical field
The present invention relates to marine engine fuel system, particularly the seperator of marine engine fuel system.
Background technology
Boats and ships discharge oily waste water after combustion material in navigation process, if oily waste water directly discharges meeting sternlyHeavily contaminated environment, therefore needs waste water to carry out water-oil separating processing, generally realizes by oil-water separator.The shortcoming that existing oil-water separator exists is that the sealing effectiveness between end cap and the body of seperator is not good, due toVibration when ship's navigation and engine operation, causes hermetically-sealed construction absent-mindedness, occurs oil leakage phenomenon, impact pointThe work of disembarking.
Summary of the invention
The above-mentioned shortcoming that the applicant exists for boats and ships seperator, studies and designs, and provides a kind of pointThe also layer hermetically-sealed construction of disembarking, it has feature simple in structure, sealing property is good.
In order to address the above problem, the present invention adopts following scheme:
An also layer hermetically-sealed construction for seperator, comprises the seal being installed between end cap and seperator body,Described seal comprises symmetrically arranged sealing ring, and the contact-making surface of described sealing ring and end cap is with intermediate flangeAnd lateral flanges, described lateral flanges is symmetricly set in the both sides of intermediate flange, described lateral flanges and end capClose contact, has deformation gap between described intermediate flange and end cap; The inner side of described sealing ring is with fluted,In groove, device has spring and pad, and pad contacts with the bottom surface of groove, the end of spring and seperator bodyTouch.
Technique effect of the present invention is:
The present invention adopts and the close ring structure of layer, realizes the double-layer seal between end cap and seperator body, and it is closeSeal effective; Sealing ring arranges deformation gap and spring buffer structure, prevents that hard extruding from losing sealing effectiveness,Improve the reliability using.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1, the also layer hermetically-sealed construction of the seperator of the present embodiment, comprises being installed on end cap 1 and dividingThe disembark seal of 2 of bodies, seal comprises symmetrically arranged sealing ring 3, sealing ring 3 and end cap 1Contact-making surface with intermediate flange 31 and lateral flanges 32, lateral flanges 32 is symmetricly set in intermediate flange31 both sides, lateral flanges 32 and end cap 1 close contact, have deformation between intermediate flange 31 and end cap 1Gap 6; It is fluted 33 that be with the inner side of sealing ring 3, and in groove 33, device has spring 4 and pad 6, pad6 contact with the bottom surface of groove 33, and the end of spring 4 and seperator body 2 touch.
The present invention adopts and the close ring structure of layer, realizes the double-layer seal between end cap and seperator body, and it is closeSeal effective; Sealing ring arranges deformation gap and spring buffer structure, prevents that hard extruding from losing sealing effectiveness,Improve the reliability using.
