Abstract
The utility model discloses a mechanical seal comprising a flange plate, wherein the middle of the flange plate is provided with a rotating shaft, a static ring is arranged between the flange plate and the rotating shaft and at the periphery of the lower end of the rotating shaft, a dynamic ring is arranged above the static ring, the periphery of the upper end of the rotating shaft is provided with an oil seal, a bearing and a fixing assembly from top to bottom, and a spring is connected between the bearing and the fixing assembly. The mechanical seal is favorable in sealing performance, free of addition of redundant substances polluting materials, convenient to carry because of small size, and convenient to operate because no racks are additionally installed in actual application.
Description
Technical field
The utility model relates to a kind of seal arrangement, is specifically related to a kind of mechanical seal.
Background technique
At present, glassed steel reaction vessels is by the glass containing high silicon dioxide in the prior art, lining is at the internal surface of Steel Vessel, through high temperature sintering and securely adherence becomes composite product on metal surface, it has the stability of glass and the two-fold advantage of metal strength, it is a kind of good corrosion resistant apparatus, existing vesselseals is all with cooling jacket, in cooling jacket, to pass into cold water and reach cooling effect, so just have an opportunity to the material contamination in reactor, and this mechanical seal volume and weight is all very large, be inconvenient to carry, in addition, during the actual use of existing mechanical seal, need other installation frame, then speed reducer and motor are installed in frame, operation is trouble comparatively.
Model utility content
The purpose of this utility model is the deficiency existing in order to overcome prior art, and a kind of mechanical seal is provided, and it does not have cooling jacket, good airproof performance and can not add unnecessary material contaminated materials, the little convenient carrying of volume, does not need to settle in addition frame, easy-to-operat during actual use.
For achieving the above object, the technical solution of the utility model is as follows:
, comprising flange plate, the middle part of flange plate is provided with rotating shaft, it is characterized in that, and between described flange plate and described rotating shaft and be positioned at peripheral place, this rotating shaft underpart and be provided with stationary ring, this stationary ring top is provided with rotating ring; Be positioned at periphery, described rotating shaft upper end portion oil sealing, bearing and fixing-assembly are installed from top to bottom, between described bearing and described fixing-assembly, be connected with a spring.
Preferably, described stationary ring cover has O type circle, and above this stationary ring, is surrounded with stationary ring pad.
Preferably, between described rotating ring and described rotating shaft, be provided with O type circle.
The utility model beneficial effect: have good sealing, can not add unnecessary material contaminated materials, the little convenient carrying of volume, does not need to settle in addition frame, easy-to-operat during actual use.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described.
Fig. 1 is the sectional view of mechanical seal provided by the utility model;
Numeral and the represented corresponding part title of letter in figure:
1. oil sealing 2. bearing 3. spring 4. fixing-assembly 5.O type circles
6. rotating ring 7. stationary ring pad 8. stationary ring 9. flange plate 10. rotating shafts
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of mechanical seal, comprises flange plate 9, and the middle part of flange plate 9 is provided with rotating shaft 10, and between flange plate 9 and rotating shaft 10 and be positioned at peripheral place, this rotating shaft 10 underparts and be provided with stationary ring 8, these stationary ring 8 tops are provided with rotating ring 6; Be positioned at rotating shaft 10 peripheries, upper end portion oil sealing 1, bearing 2 and fixing-assembly 4 are installed from top to bottom, between bearing 2 and fixing-assembly 4, be connected with a spring 3.
Wherein, stationary ring 8 covers have O type circle 5, and are surrounded with stationary ring pad 7 above this stationary ring 8, are also provided with O type circle 5 between rotating ring 6 and rotating shaft 10.
The utility model provides a kind of mechanical seal, has good sealing, can not add unnecessary material contaminated materials, and the little convenient carrying of volume, does not need to settle in addition frame, easy-to-operat during actual use.
It is more than a kind of mechanical seal embodiment's that the utility model is proposed description, to these embodiments' multiple modification, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
