Abstract
The utility model relates to a nodal point type side-teeth labyrinth air seal which comprises a sealing ring which is arranged between a casing and a rotary shaft and is positioned by a leaf spring, wherein the side surfaces of protruded straight teeth of the sealing ring are provided with side teeth which are parallel to the rotary shaft and are perpendicular to straight teeth. The utility model has the characteristics of simple structure, good sealing effect, etc., and is suitable for sealing liquid and air.
Description
Technical field the utility model relates to a kind of labyrinth seal structure.Especially a kind of node type side tooth labyrinth gland that is used for rotatingshaft axial seal.
Background technique is present, and extensively the labyrinth seal structure that adopts is the resistance that produces when utilizing fluid to pass through the labyrinth, and the fluid self kinetic energy is consumed gradually, and flow reduces thereupon; The final sealing state of realizing.But in actual applications because the restriction of many conditions, for example: occur situations such as vibration in the rotatingshaft operation process, cause the gap between labyrinth teeth and the axis body to become big, influence sealing effect, problems such as appearance leakage and seepage.
The summary of the invention the purpose of this utility model provides the node type side tooth labyrinth gland preferably of a kind of sealing effect.
For achieving the above object, the labyrinth gland of the utility model node type side tooth comprises between casing and rotatingshaft and by the seal ring of spring positioning, the outstanding straight-tooth side of described seal ring is provided with the side tooth.
After adopting said structure,, increased the length that fluid flows on the one hand, increased the resistance when fluid flows forward on the other hand owing to be provided with the side tooth in outstanding straight-tooth side; So can reduce self kinetic energy of fluid effectively, be translated into heat energy, reduce the displacement of fluid, reach and prevent the purpose revealing, seal.
As further improvement of the utility model, described side tooth is parallel with rotatingshaft and vertical straight-tooth setting.Adopt this structure the chamber, labyrinth can be radially non-connection node structure, can avoid fluid to enter the turbulation that occurs behind the chamber, labyrinth, improve the stability of rotatingshaft work.
The utility model has the advantages that: simple in structure, sealing effect is better; Below in conjunction with drawings and Examples the utility model is described in further detail.
Description of drawings Fig. 1 is the structural representation of the utility model node type side tooth labyrinth gland.
Fig. 2 is for showing the enlarged diagram of the adjacent outstanding straight-tooth of seal ring as Fig. 1.
Embodiment as shown in Figure 1.The labyrinth gland of the utility model node type side tooth comprises between casing 1 and rotatingshaft 2 and by the seal ring 4 of spring sheet 3 location, described seal ring 4 outstanding straight-tooth 5 sides are processed with side tooth 6.Described side tooth 6 is and rotatingshaft 2 parallel and vertical straight-tooth 5 layouts.Said structure has increased the length that fluid flows on the one hand owing to be provided with the side tooth in outstanding straight-tooth side, has increased the resistance when fluid flows forward on the other hand; In fluid enters Seal cage, because flow section enlarges, in the chamber, form vortex, this moment, the side tooth can reduce self kinetic energy of fluid effectively, was translated into heat energy, reduced the displacement and the amount of leakage of fluid; Prevent the purpose revealing, seal thereby reach.The chamber, labyrinth can be simultaneously non-connection node structure radially, can avoid fluid to enter the turbulation that occurs behind the chamber, labyrinth, improve the stability of rotatingshaft work.
The utlity model has characteristics such as simple in structure, that sealing effect is better; Be applicable to the sealing of liquid, gas.
