Abstract
The seal ring of bypass valve in a kind of diesel engine cooler, comprise a seal ring body, a conical surface is arranged in the position, middle and lower part of described seal ring body outer wall, and the minimum outer diameter of this conical surface is less than the internal diameter of fixed cover, and the maximum outside diameter of this conical surface is greater than the internal diameter of fixed cover; An inverted cone face is arranged in described seal ring inner body wall middle and lower part, and the minimum outer diameter in this inverted cone face is less than the external diameter of rotating shaft, and the maximum outside diameter in this inverted cone face is greater than the external diameter of rotating shaft.The designed bypass valve seal ring of the utility model, it greatly facilitates it and installs on the basis ensureing sealing ring tightness energy, and effectively can promote the flexibility of axis of rotation.
Description
Technical field
The utility model relates to a kind of bypass valve of diesel engine cooler, is specially the seal ring of bypass valve in diesel engine cooler.
Background technique
Whether wherein have a class diesel engine cooler, it is in order to tackle the needs of Under Different Work Condition of Engine, can arrange a bypass valve and cool to control waste gas, meet the needs of motor real work with this in cooler.
At this, as shown in Figure 1, for the structural representation of existing bypass valve, fixed plate 2 ' is wherein connected with adopting between fixed cover 3 ' to weld, and rotating shaft 1 ' and fixed cover 3 ', adopt Spielpassung between lubricating sleeve 4 ', to ensure that rotating shaft 1 ' can flexible rotating, and cover plate 6 ' is set at fixed cover 3 ' top.In above structure, due to rotating shaft 1 ', the existence in gap between fixed cover 3 ' and lubricating sleeve 4 ', waste gas will inevitably leak from this gap, for this reason, existing way is provided with a seal ring 5 ' above lubricating sleeve 4 ', but sealing circle 5 ' is a common elasticity 0 type circle, its structure as shown in Figure 2, the external diameter of seal ring 5 ' outer side surface and the internal diameter of inner side surface such as are all at the large structures, and in order to ensure sealing, seal ring 5 ' must with fixed cover 3 ', rotating shaft 1 ' seals respectively, namely the whole outer wall 51 ' of seal ring 5 ' will be sealed and matched with fixed cover 3 ' endoporus, the whole inwall 52 ' of seal ring 5 ' will be sealed and matched with rotating shaft 1 ', and the sealing configuration of this bump contact arranges and on the one hand brings difficulty to the installation of seal ring 5 ', the resistance that simultaneously rotating shaft 1 ' can be caused to rotate increases greatly, have a strong impact on the flexibility of rotating shaft 1 '.
Model utility content
For the problems referred to above, the utility model devises the seal ring of bypass valve in a kind of diesel engine cooler, and it greatly facilitates it and installs on the basis ensureing sealing ring tightness energy, and effectively can promote the flexibility of axis of rotation.
For achieving the above object, the utility model is by the following technical solutions:
The seal ring of bypass valve in a kind of diesel engine cooler, comprise a seal ring body, it is characterized in that: a conical surface is arranged in the position, middle and lower part of described seal ring body outer wall, the minimum outer diameter of this conical surface is less than the internal diameter of fixed cover, and the maximum outside diameter of this conical surface is greater than the internal diameter of fixed cover; An inverted cone face is arranged in described seal ring inner body wall middle and lower part, and the minimum outer diameter in this inverted cone face is less than the external diameter of rotating shaft, and the maximum outside diameter in this inverted cone face is greater than the external diameter of rotating shaft.
Further, above-mentioned seal ring body bottom portion is provided with the distortion groove increasing body inside and outside wall middle and lower part deformation performance.
Further, the skeleton that can increase bulk strength is provided with in above-mentioned seal ring body.
The inside and outside wall of seal ring body of the present utility model is not all wait gauge structure, but as required, the middle and lower part of body outer wall is arranged to part and the conical surface of fixed cover endoporus interference fit, the middle and lower part of inner body wall is arranged to part and the inverted cone face of rotating shaft outer wall interference fit, this vibrational power flow can ensure seal ring and fixed cover well, sealability between rotating shaft, and effectively can reduce seal ring and contact with sealing between the two long-pending, such vibrational power flow not only facilitates the assembling of seal ring, effectively can reduce the rotational resistance of rotating shaft simultaneously, promote the rotation flexibility of rotating shaft.
At this, for promoting the deformation performance in inverted cone face in upper conical of body outer wall and inner body wall further, described body bottom portion is provided with the distortion groove of indent.
In addition, for strengthening the bulk strength of whole seal ring and promoting working life, in described seal ring body, corresponding skeleton can be embedded.
Accompanying drawing explanation
The structural representation of Fig. 1, diesel engine bypass valve;
The structural representation of Fig. 2, existing bypass valve seal ring;
The structural representation of Fig. 3, the utility model seal ring;
Fig. 4, seal ring are arranged the structural representation of skeleton.
Embodiment
As shown in Figure 3, the seal ring of bypass valve in a kind of diesel engine cooler, comprise a seal ring body 1, a conical surface 11 is arranged in the position, middle and lower part of described seal ring body 1 outer wall, the minimum outer diameter of this conical surface 11 is less than the internal diameter of fixed cover, and the maximum outside diameter of this conical surface 11 is greater than the internal diameter of fixed cover.An inverted cone face 12 is arranged in described seal ring body 1 inwall middle and lower part, and the minimum outer diameter in this inverted cone face 12 is less than the external diameter of rotating shaft, and the maximum outside diameter in this inverted cone face 12 is greater than the external diameter of rotating shaft.
In above structure, the inside and outside wall of seal ring body 1 is not all wait gauge structure, but as required, the middle and lower part of body 1 outer wall is arranged to part and the conical surface 11 of fixed cover endoporus interference fit, the middle and lower part of body 1 inwall is arranged to part and the inverted cone face 12 of rotating shaft outer wall interference fit, this vibrational power flow can ensure seal ring and fixed cover on the one hand well, sealability between rotating shaft, effectively can reduce seal ring to amass with sealing contact surface between the two simultaneously, the vibrational power flow of such part contact sealing not only facilitates the assembling of seal ring, effectively can reduce the rotational resistance of rotating shaft simultaneously, promote the rotation flexibility of rotating shaft.
The distortion groove 13 of indent is provided with bottom described body 1, the design of this distortion groove 13, not only can promote the deformation performance in inverted cone face 12 in the upper conical face 11 of body 1 outer wall and inner body wall further, the rotational resistance that inverted cone face 12 countershaft is formed can be reduced simultaneously to a certain extent.
In addition, for strengthening the bulk strength of whole seal ring and promoting working life, can embed corresponding skeleton 14 in described seal ring body 1, its structure as shown in Figure 4.
The above, it is only better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solutions of the utility model.
