Abstract
The utility model discloses an elastic compensating type Y-shaped combined sealing ring, comprising an elastomer energy storage ring 1 and a Y-shaped ring 2, wherein the elastomer energy storage ring is inlaid in a concave groove at a bearing end of the Y-shaped ring, and the elastomer energy storage ring and the concave groove jointly form the sealing ring; the root part of the inner circumference of the Y-shaped ring is provided with a sealing lip which can improve the stability of the entire Y-shaped combined sealing ring after being mounted in a groove; and the cross section of the elastomer energy storage ring is V-shaped, and the middle part of the bearing end of the elastomer energy storage ring is provided with an opening. The elastic compensating type Y-shaped combined sealing ring is mainly used for sealing a reciprocating hydraulic cylinder in a hydraulic transmission control system, has excellent sealing performance under the condition of higher pressure or lower pressure of the hydraulic cylinder, and can keep the sealing state of zero leakage in the bearing range of 0-40Ma.
Description
Technical field
The utility model relates to the seal arrangement of the piston rod of reciprocating oil hydraulic cylinder in a kind of hydraulic transmission control system, particularly a kind of elastic compensation Y shape combined seal ring.
Background technique
At present, mostly the seal arrangement that is widely used in the piston rod of reciprocating oil hydraulic cylinder in the hydraulic transmission control system is that Y shape circle adds O shape back-up ring, though its frictional force is little, motion is steady, and institute's pressure range of bearing is wider, but deficiency is, when bearing low pressure, its sealability reduces greatly.
The model utility content
The shortcoming that the purpose of this utility model is to overcome prior art provides a kind of simple and reasonable for structure with not enough, can bear the pressure range than broad, when particularly bearing low pressure, and the elastic compensation Y shape combined seal ring of favorable sealing property.
The purpose of this utility model is achieved through the following technical solutions: a kind of elastic compensation Y shape combined seal ring, comprise Y shape circle, elastomer energy storage ring, described elastomer energy storage ring is embedded in the groove of compression end of Y shape circle, and the heel of the inner circumference of described Y shape circle has seal lip.
As a kind of preferred structure, the sectional shape of the seal lip of described Y shape circle is semicircle, triangle or trapezoidal.
As a kind of preferred structure, described seal lip is more than one or one.
As a kind of preferred structure, the sectional shape of described groove is a V-arrangement, and the sectional shape of elastomer energy storage ring correspondingly also is a V-arrangement.
As a kind of preferred material, the material of described Y shape circle is a polyurethane material, and the material of elastomer energy storage ring is a nitrile rubber.
As a kind of preferred structure, there is opening at the middle part of the compression end of described elastomer energy storage ring, and the opening section shape can be semicircle, triangle, rectangle or trapezoidal.
The utility model compared with prior art has following advantage and beneficial effect:
1, the elastomer energy storage ring that utilizes nitrile butadiene rubber to make has the high-quality rebound elasticity, is 0 o'clock as pressure, the outside of the groove of Y shape circle is opened, and keep enough elasticity pretightening forces, guarantees that Y shape circle has very good low pressure seal performance.
2, the advantage of comprehensive Y shape circle of the utility model and elastomer energy storage ring can adapt to the pressure range of oil hydraulic cylinder than broad, experiment showed, that its minimum adaptation pressure is 0MPa, and the highest adaptation pressure is 40MPa.
Pressure transmission medium when 3, the utility model is worked not only can be a normal hydraulic oil, can also be fluids such as water, water glycol, emulsified liquid.
4, the root of the inner circumference of Y shape circle of the present utility model has seal lip, improves the stability after whole Y shape combined seal ring is installed.
