A kind of above-mentioned sealed protective structure, the inner surface of the leaking medium accommodating chamber is sphere.
A kind of above-mentioned sealed protective structure, the quantity of the leaking medium accommodating chamber is at least one.
A kind of above-mentioned sealed protective structure, the lower end of the sealing gland is connected provided with guiding gutter and with guiding gutter
Discharge orifice.
A kind of above-mentioned sealed protective structure, the sealing gland is filling material seal gland or mechanical seal cover.
A kind of above-mentioned sealed protective structure, the quantity of the protrusion is at least one.
A kind of above-mentioned sealed protective structure, the surfaces externally and internally of the seal is respectively equipped with sealing inner sleeve, hermetically sealed case.
The utility model carries out deep processing on the basis of original part, without extra increase parts, without more
Installing space, had both solved the problem of medium after sealing leak is thrown out of splashes, and the medium that can be will leak out again is returned
Receive.
The utility model is described in further details below with reference to drawings and Examples.

Embodiment
Reach technological means and effect that predetermined purpose is taken for the utility model is expanded on further, below in conjunction with accompanying drawing
And embodiment is to embodiment of the present utility model, architectural feature and its effect, describe in detail as follows.
Embodiment 1：
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of sealed protective structure, including housing, sealing gland 1, rotary shaft 2, seal 3,
Axle sleeve 4, housing places the accommodating chamber of seal 3 with the formation of axle sleeve 4, and axle sleeve 4 is set in rotary shaft 2, and sealing gland 1 is set in
On axle sleeve 4, sealing gland 1 is fixed and compresses seal 3, and the inwall of the sealing gland 1 is provided with leaking medium accommodating chamber 11, axle
The outer circumference surface of set 4 is provided with protrusion 41, and the purpose that protrusion 41 is set on axle sleeve 4 is prevent leakage medium osmosis to housing；
The inner surface of leaking medium accommodating chamber 11 is sphere, and the leaking medium accommodating chamber 11 can approx regard bowl-shape as；Leakage
Medium accommodating chamber 11 is at least one.Leaking medium accommodating chamber 11 is used for accepting the medium of leakage.
The inner surface of the leaking medium accommodating chamber is sphere；The design of the sphere can together with whole leaking medium accommodating chamber
Approximately to see bowl-type cavity 2 as, operationally, sealing is once produce leakage, and the medium leaked out is rotating for rotary pump
Axle sleeve be thrown on bowl-type cavity inner wall face, by the bowl-type cavity in gland to being thrown out of the reaction of medium, stop a leak
The radial velocity of medium, now only the leaking medium of peripheral speed only carries out circular motion in bowl-type cavity, i.e., can not be by
The medium of leakage is thrown away.
Embodiment 2：
Part unlike the embodiments above, be also include positioned at the bottom of leaking medium accommodating chamber 11 guiding gutter 12 and
The discharge orifice 13 being connected with guiding gutter 12；Discharge orifice 13 is perpendicular to rotary shaft 2.
Axle sleeve 4 is arranged with rotary shaft 2, leaking medium accommodating chamber 11 is located between sealing gland 1 and axle sleeve 4.
In order to reach good sealing, seal 3 can be set between rotary shaft 2 and housing, inside and outside seal 3
Surface sets sealing inner sleeve 31, hermetically sealed case 32 respectively；Seal 3 can be mechanical parts or filler, corresponding sealing gland
Can be mechanical seal cover or filling material seal gland.
When rotary shaft 2 is running at high speed, seal 3 is once produce leakage, and the medium leaked out is thrown to by rotary shaft 2
On the inwall of leaking medium accommodating chamber 11, by the reaction on the inwall of leaking medium accommodating chamber 11, by medium of stopping a leak
Radial load, in the presence of leaking medium axial force, leaking medium moves in a circle in leaking medium accommodating chamber 11, so that logical
Guiding gutter 12, discharge orifice 13 is crossed to will leak out medium and discharge and be collected.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
