Abstract
The invention discloses a diesel oil filter seal ring. The diesel oil filter seal ring comprises a fixing screw, a front washer, a pressing flange, a pressing sleeve, a seal ring body, an annular seal seat and a back washer, wherein the back washer is mounted at the bottom of the seal seat in a pressed manner, the seal ring body is mounted on the back washer in a pressed manner, the pressing sleeve is mounted on the seal ring body in a pressed manner, the pressing flange is mounted on the pressing sleeve in a pressed manner, and the front washer is fixedly mounted on the pressing flange through the fixing screw. The diesel oil filter seal ring has the advantages of exquisite structure, high sealability and capability of well preventing diesel oil leakage.
Description
Technical field
The present invention relates to seal ring field, particularly a kind of diesel-oil filter seal ring.
Background technique
The selection of sealing ring material to its sealability and working life important in inhibiting.The performance of material directly affects the usability of seal ring, and the performance that seal ring should possess comprises high resilience and rebound elasticity; Suitable mechanical strength, comprises tensile strength, elongation percentage and tearing toughness etc.Stable performance, not easily swelling in media as well, thermal pinch (joule effect) is little.Easy machine shaping, and accurate size can be kept.Do not corrode surface of contact, not pollution medium etc.Applicable and the most the most frequently used material meeting above-mentioned requirements is rubber, so the large multiplex rubber material of seal ring is made.The kind of rubber is a lot, and constantly has new rubber clone to occur, designs with when selecting, should be appreciated that the characteristic of various rubber, choose reasonable.Seal ring, in working pressure and certain temperature range, should have good sealability, and automatically can improve sealability along with the increase of pressure.. the frictional force between gasket set and movement parts is little, and friction factor will be stablized.Seal ring anti-corrosion capacity is strong, and not easily aging, long working life, wear resistance is good, to a certain extent can auto-compensation after wearing and tearing.Structure is simple, uses, easy to maintenance, makes seal ring have the longer life-span.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of delicate structure, good seal performance, can be good at the diesel-oil filter seal ring preventing diesel oil from leaking, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technological scheme: a kind of diesel-oil filter seal ring, be made up of retaining screw, front packing ring, supported flange, gland, seal ring, sealing seat and rear packing ring, the shape of sealing seat is annular, and rear packing ring compresses and is arranged on sealing seat lowest part, and seal ring compresses and is arranged on above rear packing ring, gland compresses and is arranged on above seal ring, supported flange compresses and is arranged on above gland, and front packing ring is arranged on supported flange, is fixed by retaining screw.
Preferably, described sealing seat is three grades of cascade loop configuration.
Preferably, the inwall of described sealing seat is provided with polytetrafluorethylecoatings coatings.
Preferably, described gland surface is provided with hackle mark.
Preferably, described seal ring is " J " RunddichtringO.
Preferably, described front packing ring and rear washer face are provided with PP film.
Adopt the beneficial effect of above technological scheme to be: sealing seat is three grades of cascade loop configuration, such design by cutting unit in seal ring, can not affect the effect of its sealing, the sealing effect of whole seal ring is improved greatly each other; The inwall of sealing seat is provided with polytetrafluorethylecoatings coatings, and such design can prevent oil pollution seal ring, reduces its sealability; Gland surface is provided with hackle mark, the gap that such design can make gland be filled with a sealing between the interior each part of circle, lift-off seal; Seal ring is " J " RunddichtringO, and such design makes seal ring and compacting between gland and sealing seat, prevents seal ring from occurring to loosen; Front packing ring and rear washer face are provided with PP film, and such design has completely cut off moisture and air to the corrosive action of part, extends the working life of seal ring; The overall structure of sealing circle is exquisite, and the design of front and back packing ring makes each part compacting of seal ring, enhances the sealing effect of seal ring.
