Problems solved by technology
[0005] The invention provides an elastic energy storage sealing assembly to solve the problem that the opening of the U-shaped jacket of the spring energy storage sealing ring faces the side of the system fluid medium, so that the spring is in direct contact with the fluid medium and is prone to corrosion; while the U-shaped jacket The side of the opening away from the fluid medium of the system cannot be self-tightened by the pressure of the fluid medium, and the technical problem that the sealing cannot be guaranteed under high pressure

Embodiment Construction
[0032] In the prior art, for fluid conveying and related equipment, the sealing method usually uses a spring energy-storage sealing ring for sealing. Wherein, the elastic energy storage sealing ring includes a U-shaped jacket and a spring inside the U-shaped jacket. The opening of the U-shaped jacket of the spring energy storage sealing ring faces the side of the system fluid medium, so that the spring is in direct contact with the fluid medium, which is prone to corrosion; while the opening of the U-shaped jacket is away from the system fluid medium side and cannot be used automatically by the pressure of the fluid medium. Tight, can not guarantee the technical problem of sealing under high pressure.
[0033] In view of this, the present invention provides an elastic energy storage sealing assembly, which realizes the self-tightening seal of the first elastic jacket under high pressure by means of fluid medium pressure by arranging the accommodation grooves of the first elast...

The invention provides an elastic energy storage sealing assembly. The elastic energy storage sealing assembly comprises a first elastic jacket, a second elastic jacket and an elastic piece; one end of the first elastic jacket is connected with one end of the second elastic jacket, a first accommodating groove is formed in the other end of the first elastic jacket, and an opening of the first accommodating groove faces one side of fluid; a second accommodating groove is formed in the other end of the second elastic jacket, and an opening of the second accommodating groove deviates from one side of the fluid; and the elastic piece is located in the second accommodating groove and abuts against the side wall of the second accommodating groove. According to the elastic energy storage sealingassembly, by arranging the accommodating grooves of the first elastic jacket and the second elastic jacket back to back, the conditions of self-tightening sealing of the first elastic jacket under high pressure by means of fluid medium pressure and sealing of the second elastic jacket and the elastic piece under low pressure by means of elastic force of the elastic piece are achieved, and the sealing performance is improved; and the elastic piece is separated from a fluid medium, so that the service life of the elastic piece is prolonged.
Description
technical field [0001] The invention relates to the technical field of sealing, in particular to an elastic energy storage sealing assembly. Background technique [0002] The sealing device is an important structure to ensure the normal operation of mechanical equipment. It is mainly used to control the leakage behavior of the mechanical structure and ensure the safe and normal operation of the mechanical structure. For example, in fluid conveying and related equipment, the sealing performance is required to be high, and the sealing performance of the sealing device is particularly critical. [0003] In fluid conveying and related equipment, the sealing method is usually sealed by spring energy sealing ring. Wherein, the elastic energy storage sealing ring includes a U-shaped jacket and a spring inside the U-shaped jacket. There are usually two ways to install the spring energy storage sealing ring. One is that the opening of the U-shaped jacket faces the side of the syste...
