Abstract
The present invention uses the theory of fluid mechanics to provide a full-new sealing structure.
Description
Field under the present invention is a mechanical field
The present invention utilizes hydromechanical principle, and purpose is to provide a kind of effective seal mode, and concrete characteristics show following several aspect:
1, on relative two sealing surfaces that reasonable clearance arranged, is covered with semicircular pitting,, can reaches to intercept and leak when fluid is under pressure or during two sealing surface relative movement, forms vortex at a high speed in the pitting
2, the invention belongs to a kind of dynamic seal (packing) mode, the big I of its semicircle pitting is rationally arranged according to the area that sealing strip provides, and it intercepts the ability of leaking and is directly proportional with the pressure of fluid and the speed of relative movement.
For realizing above-mentioned purpose of the present invention, its concrete technological scheme is as follows:
1, cellular-shaped densely covered semicircle pitting can adopt the mode of cast form, can also process with drill bit.
2, cellular densely covered semicircle pitting, can on any relative cambered surface or plane, arrange by, staggered with pitting is good, can guarantee bigger flow-disturbing like this, reaches better sealing effect
3, cellular densely covered pitting can be arranged on a relative face, can also arrange on two relative faces
According to above characteristics and technological scheme, provide structure principle chart of the present invention and position view.
Fig. 1 is a position view of the present invention
Fig. 2 is a structure principle chart of the present invention
Each several part title among the figure:
1, semicircle pitting;
2, motion sealing surface;
3, relative sealing surface;
Below in conjunction with accompanying drawing, provide most preferred embodiment of the present invention.
A, embodiment one are most preferred embodiment of the present invention as shown in Figure 1 and Figure 2, and its structure division is familiar with by Fig. 1, Fig. 2 and above accompanying drawing.
It below is working principle explanation of the present invention.
Fluid is under pressure or relative movement state, and the fluid of storage in semicircle pitting changes the direction of escape of liquid with the rotation of certain speed, reaches the counteracting of self power, realizes sealing.
Claims (2)
1, the sealing in two relatively reasonable gaps of the present invention and on, be covered with semicircle pitting simultaneously on the face or on two faces, be cellular structure, the fluid that the pressurized that passes through or relative movement are formed produces vortex and causes to intercept and leak
2, according to claim 1, the corresponding sealing surface of the present invention can be any type of arc shaped surface or plane
