Abstract
The utility model relates to a sealing ring which comprises an annular ring body. The utility model is characterized in that the upper end surface and the lower end surface of the annular ring body are respectively provided with an annular groove, spring pieces are arranged in the annular grooves, the built-in spring pieces generate elastic deformation under the constraint of the annular grooves and have tension to the walls of the annular grooves, a working surface of the sealing ring is in a structure with high both sides and a low middle, the annular ring is made from abrasion resistant, refractory and strong acid-base corrosion resistant engineering plastic and has little probability of aging, and the spring pieces are made from metal which has little probability of aging and rusting. The sealing ring has the advantages of good sealing effect and long service life, reduces the number device maintenance and causes production to be more easily carried out.
Description
Technical field
The utility model relates to shaft sealer, specifically, relates to the seal ring that a kind of shaft sealer is used.
Background technique
The seal ring of shaft sealer use at present generally adopts the O RunddichtringO, the O RunddichtringO produces prestressing force by the extrusion-deformation of when assembling and reaches sealing effect, its simple in structure, withstand voltage height, volume are little, but because seal ring weares and teares in movement process greatly, and it is in deformation state for a long time, elasticity can not keep well, in order to make the O RunddichtringO have certain elasticity, it is generally made with silica gel, this material non-refractory, easily aging, so that working life is short, needs often to change.Because seal ring is a critical component, must shut down during replacing, causes bad influence to ordinary production.
Summary of the invention
For remedying the deficiencies in the prior art, the utility model provides a kind of seal ring, and the technological scheme of employing is as follows:
This seal ring comprises a ring-type circle body, it is characterized in that: the ring-type circle body be respectively equipped with a circular groove on two end faces up and down, circular groove is built-in with spring sheet, built-in spring sheet is subjected to circular groove constraint to produce elastic strain, and annular groove wall is had a tension force.
The external frame of above-mentioned circular groove shape and ring-type circle body end face is complementary, and makes the ring slot outside wall thickness even, thereby makes seal ring balancing performance everywhere.
Above-mentioned built-in spring sheet is evenly distributed in the circular groove.
The seal ring working surface is structure low between the senior middle school of two ends.
The annular circle body is made by engineering plastics wear-resistant, high temperature resistant, the strong acid-base resistance corrosion, is difficult for wearing out, and spring sheet is made by being difficult for metal aging and that be difficult for getting rusty.
Having adopted chip architecture of the spring in the seal ring, thus can reduce the flexible requirement of seal ring self, thus can adopt elasticity lower and wear resistance and ageing resistance material, for example engineering plastics etc. preferably.Because the working surface two ends are equivalent to the two seals circle, thereby can further improve sealing effect.Because engineering plastics that seal ring adopted and spring sheet are difficult for aging, owing to built-in spring sheet annular groove wall there is a tension force again, when wear and tear in the outside of seal ring (being working surface), the attenuation of ring slot outside wall, the suffered restraining force of spring sheet diminishes, just open automatically, the ring slot outside wall is outwards expanded, the gap between the compensation sealing circle and the pump housing, avoided the generation of leaking, therefore seal ring has long working life, reduces the device maintenance number of times, and production is more successfully carried out.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structural representation;
Fig. 2 is an A-A sectional view among Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, seal ring in this preferred embodiment comprises a ring-type circle body, be respectively equipped with the circular groove 2 that the external frame of a shape and ring-type circle body end face 1 is complementary on two end faces 1 up and down of ring-type circle body, circular groove 2 outer side walls 3 thickness are even, evenly be provided with spring sheet 4 in the circular groove 2, built-in spring sheet 4 is subjected to circular groove 2 constraints to produce deformation, and circular groove 2 walls are had a tension force.
The ring-type circle body is made by engineering plastics wear-resistant, high temperature resistant, the strong acid-base resistance corrosion, is difficult for wearing out, and built-in spring sheet 4 is made by being difficult for metal aging and that be difficult for getting rusty.
Seal ring working surface 5 is structure low between the senior middle school of two ends, is equivalent to the two seals circle, further improves sealing effect.
Because engineering plastics that seal ring adopted and spring sheet 4 are difficult for aging, again because there is a tension force 4 pairs of circular groove 2 two sides of built-in spring sheet, when wear and tear in the outside of seal ring (being working surface 5), 3 attenuation of circular groove 2 outer side walls, spring sheet 4 suffered restraining forces diminish, and just open automatically, circular groove 2 outer side walls 3 are outwards expanded, gap between compensation sealing circle and the sealing surface avoided the generation of leaking, so seal ring has long working life.
