Sealing element is that fluid is prevented from the important spare part leaked between adjacent faying face, to be widely used though sealing element is small, aviation, boat
The industries such as sea, oil, chemical industry, machinery, power generation, metallurgy, mine all be unable to do without sealing element.Common sealing element is had by shape to divide
O-ring seal, y-type seal ring, V-shaped seal ring, YX types sealing ring, square seal ring, U-shaped sealing ring etc., different type sealing
Part action principle is different, according to different working conditions select use, there are the problem of be single sealing ring sealing effect
Limited, if be applied in combination with multiple separated sealing rings, sealing position is oversized, while also is difficult to what is be optimal
Matching and best sealing effect.
The content of the invention
The utility model provides a kind of interior bag skeleton composite seal, to reach more effectively sealing anti-leak purpose.
The technical solution adopted in the utility model is：A kind of interior bag skeleton composite seal seals 1 He including compounded rubber
Interior Baogang's skeleton 2, compounded rubber sealing 1 are internally provided with interior Baogang's skeleton 2；The compounded rubber sealing 1 includes the V-arrangement at both ends
Sealing ring11 and v-ring12 and slot sealing ring 13 between the two, three in one forms circular ring shape；The interior bag
Steel skeleton 2 includes V-arrangement skeleton21st, V-arrangement skeleton22 and ring skeleton 23, respectively with the v-ring in compounded rubber sealing 111st, v-ring12 and 13 position of slot sealing ring correspond to, ensure that sealing element has higher intensity and rigidity, avoid making
Being easily deformed in causes seal failure.
Further, the v-ring11 include v-ring endoporus lip111st, v-ring end face112 Hes
V-ring outer circle lip113；The v-ring12 include v-ring endoporus lip121st, v-ring end
Face122 and v-ring outer circle lip123；The slot sealing ring 13 includes slot ring inner hole face 131 and slot
Sealing ring arc groove 132.
The operation principle of the utility model is：The utility model is packed into static mechanical seal slot and the rotation axis rotated
Between, the v-ring end face of compounded rubber sealing 1112nd, v-ring end face122nd, v-ring outer circle lip
113rd, v-ring outer circle lip123 cell wall respectively with static mechanical seal slot contacts, and compounded rubber sealing 1 connects
Thixotroping shape has deadened fluid and has been leaked from the gap between stationary parts；Compounded rubber sealing 1 and the sealing function point of rotation axis
To deaden the effect of fluid leakage and increasing the effect of leakage path resistance, v-ring endoporus lip111 and v-seal
Enclose endoporus lip121 contact respectively with rotation axis, play the role of deadening fluid leakage, v-ring11st, v-ring12 are arranged on sealing element both ends face-to-face, and pipe fluid is not from which direction leakage, and total lip there are one v-seal is in face of stream
Body leak direction, make under the action of leak fluid pressure differential v-ring endoporus lip be more adjacent in rotation axis so as to
Increase sealing effect, therefore two way seal can be played the role of；Slot ring inner hole face 131 and slot sealing ring arc groove
The slot gap of fluid leak pressure can be reduced step by step by being formed between 132 and rotation axis, play the work for increasing leakage path resistance
With.
The beneficial effects of the utility model are：The utility model is reasonably combined with two v-rings and a slot
Sealing ring is integrated, and is played the role of deadening fluid leakage and is reduced leak pressure step by step and increase leakage path resistance, this reality
With it is new the characteristics of be simple and compact for structure, easy to use, integrated combination sealing function is with strong complementarity, and interior Baogang's skeleton causes
Sealing element has higher intensity and rigidity, the occasion more demanding applied to rotation axis seal anti-leak.
