Lead to the mounting groove；
The outer edge protrusion of the sealed body has sealing pair cutting edge, and the level height of the sealing pair cutting edge is higher than described
Seal the level height of main cutting edge；Pressure bearing and seal slot is formed between the sealing pair cutting edge and the main cutting edge of sealing, it is described close
The peripheral wall upper end for sealing main body is equipped with an at least lubrication groove；
The support guide way is installed on the mounting groove, and the support guide way is in the shape of a " convex ", the support guiding
The centre of body offers the second axis hole, and the mounting groove is equipped with stage portion, and the support guide way is equipped with matches with the stage portion
The L-shaped groove of conjunction.
Further, the upper end aperture of the first shaft hole is less than lower end aperture, and the upper end opening of the first shaft hole
Edge is in inverted "eight" shape.
Further, the smallest radial size of the mounting groove is greater than the lower end aperture of the first shaft hole.
Further, the bottom of the pressure bearing and seal slot is oblique.
Further, the aperture of second axis hole and the lower end aperture of the first shaft hole are equal.
Compared to the prior art, the high pressure resistant Wellendichtring of the utility model at the lip of sealed body by being arranged
An at least lubrication groove avoids blocking during use to effectively improve the greasy property of high pressure resistant Wellendichtring
Dead phenomenon.In addition, by the way that stage portion, the setting of support guide way and stage portion cooperation are arranged in the mounting groove of sealed body
L-shaped groove so that support guide way plays good support and guiding role, and can be fitted close with sealed body, be improved
The stability of high pressure resistant Wellendichtring, it is high pressure resistant.
Detailed description of the invention
Attached drawing is to be used to provide a further understanding of the present invention, and constitute part of specification, and following
Specific embodiment is used to explain together the utility model, but should not constitute limitations of the present invention.In the accompanying drawings,
Fig. 1: the assembling schematic diagram of the high pressure resistant Wellendichtring of the utility model；
Fig. 2: the decomposition diagram of the high pressure resistant Wellendichtring of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
As depicted in figs. 1 and 2, the high pressure resistant Wellendichtring of the utility model includes sealed body 1 and is installed on close
Seal the support guide way 2 of main body 1.
Specifically, sealed body 1 is in circular ring shape, the top center of sealed body 1 is equipped with lug boss 101, and bottom is equipped with peace
Tankage 102；Lug boss 101 offers first shaft hole 103, and the upper end aperture of first shaft hole 103 is less than lower end aperture, and first axle
The upper end opening edge in hole 103 is in inverted "eight" shape, and the upper end of first shaft hole 103, which is formed, seals main cutting edge 104, is effectively improved resistance to
The sealing performance of high pressure Wellendichtring.Further, the smallest radial size of mounting groove 102 is greater than the lower end of first shaft hole 103
Aperture, and first shaft hole 103 penetrates through mounting groove 102；After support guide way 2 is installed on mounting groove 102, due to first shaft hole
The smallest radial size that 103 lower end aperture is less than mounting groove 102 effectively avoids support to play good position-limiting action
Guide way 2 is mobile to first shaft hole 103.
In addition, the outer edge protrusion of sealed body 1 has sealing pair cutting edge 105, and the level height of sealing pair cutting edge 105 is high
In the level height for sealing main cutting edge 104.Pressure bearing and seal slot 106 is formed between sealing pair cutting edge 105 and the main cutting edge 104 of sealing,
And the bottom of pressure bearing and seal slot 106 is oblique, effectively increases the leakproofness of sealed body 1.The peripheral wall upper end of sealed body 1
An at least lubrication groove 107 is equipped at lip, to effectively improve the greasy property of high pressure resistant Wellendichtring, to keep away to hide oil
Exempt from high pressure resistant Wellendichtring and occurs stuck phenomenon during use.
Support guide way 2 is in the shape of a " convex ", and the centre of support guide way 2 offers the second axis hole 201, and the second axis hole
201 aperture is equal with the lower end aperture of first shaft hole 103.When support guide way 2 is installed on mounting groove 102, first shaft hole 103
It is communicated with the second axis hole 201.Further, mounting groove 102 is equipped with stage portion 108, and support guide way 2 is equipped with matches with stage portion 108
The L-shaped groove 202 of conjunction, so that support guide way 2 plays good support and guiding role, and can be close with sealed body 1
Cooperation, improves the stability of high pressure resistant Wellendichtring, high pressure resistant.
To sum up, the Wellendichtring of the utility model has the advantage that
