Efficient cooling swivel joint

Abstract

The invention relates to an efficient cooling swivel joint comprising a stop pin, a check ring for a first hole, a shell, a cover, an outer tube, a second O-shaped ring, a transition sleeve, a fourth O-shaped ring, a small spring, a stationary seal ring, a round pin, a static sealing ring and a motive sealing ring. The designed structure is ingenious; the original single spring blocking liquid inlet is eliminated, and the cooling medium is unobstructed, so that the cooling medium of the fully-embedded swivel joint is not blocked to cause leakage; the cooling liquid turn volume is increased by 1.5 times at the same diameter joint; the cooling effect is increased by 75%; and the efficient energy-saving effect is achieved. Multiple springs and a balanced sealing design are adopted to enable the stress at a sealing surface to be uniform and self-balanced, reduce the failure rate, and prolong the service life. A plurality of radial through holes are arranged on the thin section of the shell; the liquid inlet is smoother; and the phenomenon of blocking the liquid inlet port is completely eradicated. A outer tube cantilever beam stress part is configured as a thickened taper structure, so that the strength of the outer tube is increased, and fatigue break of the outer tube is completely eradicated.

Description

technical field [0001] The invention relates to a high-efficiency cooling rotary joint, in particular to a connecting and sealing component for transporting cooling liquid from a stationary pipeline to a rotating pipeline or rotating equipment, and belongs to the technical field of dynamic sealing devices. Background technique [0002] The rotary joint is a dynamic sealing device. It is a key basic component that automatically transports fluid media (such as cooling water, oil, gas, steam, etc.) from stationary pipelines to rotating pipelines or rotating equipment through pressure differences. , Save energy, protect the environment, and improve the working conditions of the sealing device. In the prior art, the commonly used rotary joint is a full-buried rotary joint, which mainly adopts a radial hole on the casing, and an axial cylindrical spring is installed in the casing perpendicular to the radial hole. The gasket, the gasket bears against the sealing ring, constitutes...

Problems solved by technology

However, since this type of rotary joint is installed in the end of the roll, there are often accumulated dirt, rust, and scale in the roll, which is easy to block the spring in the shell, and the spring loses its elasticity or prevents the cooling medium from entering the roll that needs to be cooled. , can not play the role of rapid cooling of the roll, and a large amount of dirt leaks out, polluting the working environment
