Abstract
The utility model discloses a high-performance combined static sealing ring, which comprises a Y-shaped supporting ring and a sealing ring. The sealing ring is placed on the Y-shaped supporting ring, the Y-shaped supporting ring made of polyurethane materials with higher hardness supports the dumbbell-shaped sealing ring and simultaneously has a certain sealing function by aid of interference of a lip of the Y-shaped supporting ring, and the dumbbell-shaped sealing ring is made of butyronitrile materials with lower hardness and better elasticity and has a main sealing function. The high-performance combined static sealing ring is fine in sealing effect and strong in adaptability, is particularly applicable to grooves with ultra-large specifications, rough and rugged surfaces and poor section size precision, wherein the grooves can not be mechanically processed but required to be polished manually.
Description
Technical field
The utility model relates to a kind of static seal device that is used for groove, particularly a kind of high-performance combination static seal circle.
Background technique
At present, in large-scale, large equipment, especially in the spiral case of large-scale hydroelectric power unit, can't adopt manual grinding by mach big specification inside and outside circle, cause inner and outer round surface roughness and radial run-out bigger.The static seal of traditional O circle stack back-up ring can't guarantee sealing effect under above-mentioned working condition, cause leakage easily.
The model utility content
The purpose of this utility model is to overcome the shortcoming of prior art with not enough, provides a kind of simple and reasonable for structure, can adapt to the flute surfaces roughness and the inside and outside circle circular runout is bigger, and the reliable high-performance combination of sealing effect static seal circle.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-performance combination static seal circle, comprise Y shape support ring and seal ring, and described seal ring is more than one or one, it is stacked in the compression end of Y shape support ring.
As a kind of preferred structure, described seal ring is 1-3.
As a kind of preferred material, the material of described Y shape support ring is a polyurethane material.
As a kind of preferred structure, described seal ring is a dumbbell-shaped structure, and its middle part is fluted, and the sectional shape of groove is circular arc, triangle, trapezoidal or rectangle.
As a kind of preferred structure, the sectional shape of described seal ring end faces of both sides is circular arc or polygonal.
As a kind of preferred material, the material of described seal ring is a nitrile rubber.
The utility model compared with prior art has following advantage and beneficial effect:
1, the seal ring that utilizes nitrile rubber to make has the high-quality rebound elasticity, can keep enough elasticity pretightening forces, guarantees that high-performance combination static seal circle has very excellent sealing ability, plays the primary seal effect.
2, the Y shape support ring that utilizes polyurethane material to make is rigid high relatively, and one or more seal ring is played the good supporting effect, relies on the interference of self lip that certain seal action is arranged simultaneously, plays time seal action.
3, the advantage of comprehensive Y shape support ring and seal ring, when the flute surfaces roughness was big relatively, test showed that this high-performance combination static seal circle still can be brought into play excellent sealing ability.
4, the advantage of comprehensive Y shape support ring and seal ring, when the inside and outside circle circular runout was big relatively, test showed that this high-performance combination static seal circle still can be brought into play excellent sealing ability.
