Abstract

The invention relates to a high-pressure rubber pipe with a water-cooling device. The high-pressure rubber pipe comprises a rubber pipe, a bellows, a first joint and a second joint, wherein the bellows is sleeved on the rubber pipe, and the belows and the rubber pipe are coaxially arranged; two ends of the rubber pipe and the bellows are respectively fixed on the first joint and the second joint; a high-temperature resistant sealing device is respectively arranged between two ends of the bellows and the first and the second joints; a cooling water cavity is formed between the inner wall of the bellows and the outer wall of the rubber pipe; and one end of the bellows is provided with a cooling water outlet, and the other end of the bellows is provided with a cooling water inlet. According to the high-pressure rubber pipe with the water-cooling device, the rubber pipe and a high-temperature environment can be separated, the rubber pipe can be ensured to work under the normal temperature, and the service life of the rubber pipe is prolonged.

Description

The high-pressure rubber pipe that has water cooling plant

Technical field

The present invention relates to a kind of sebific duct, relate to a kind of high-pressure rubber pipe that is used for metallurgy industry specifically.

Background technique

About 120 ℃ of the high-temperature resistants of existing high-pressure rubber pipe; But use the long-time high temperature in position of this high-pressure rubber pipe in industries such as metallurgy; And temperature can reach hundreds of even thousands of degree, and radiation temperature is all at 300 ℃ more than the degree, the requirement that therefore existing high-pressure rubber pipe does not reach field working conditions far away.Solution to this problem coats the heat-resistant fireproof material exactly outside high-pressure rubber pipe now; This method can only be alleviated the destruction of hyperthermia radiation to high-pressure rubber pipe in the short time; In long-time hyperthermia radiation or long term high temperature environment, also use time about 3 months even shorter at most even coat the HTHP sebific duct of heat-resistant fireproof material; Yet these high-pressure rubber pipes often are in key position, in case the high-pressure rubber pipe breakage of this position directly causes stopping production, cause immeasurable loss.

Summary of the invention

The purpose of this invention is to provide a kind of high-pressure rubber pipe that has water cooling plant, it can prolong the working life of high-pressure rubber pipe.

To achieve these goals; Technical solution of the present invention is: a kind of high-pressure rubber pipe that has water cooling plant, comprise sebific duct, and wherein also comprise bellows, first, second joint; Bellows is enclosed within on the sebific duct and bellows and the coaxial setting of sebific duct; The two ends of sebific duct and bellows are individually fixed on first, second joint, are respectively equipped with the refractory seal device between bellows two ends and first, second joint, between bellows inwall and sebific duct outer wall, form cooling water chamber; Bellows one end is provided with coolant outlet, and the other end is provided with the cooling water inlet.

The present invention has the high-pressure rubber pipe of water cooling plant; Wherein, Said first, second joint is respectively the disk that has first center hole, second center hole; The axial both sides of first center hole and second center hole are respectively fixed end, and the sebific duct two ends are bolted in respectively on the inboard fixed end of first, second center hole, and sebific duct is communicated with first, second center hole.

The present invention has the high-pressure rubber pipe of water cooling plant; Wherein, Said bellows two ends are respectively equipped with first, second fixed end, and first, second flange is fastened in respectively on first, second fixed end, and first, second flange is connected with first, second joint through screw respectively.

The present invention has the high-pressure rubber pipe of water cooling plant, and wherein, said coolant outlet is located at first neck top of bellows one end, and second neck below of the bellows the other end is located in the cooling water inlet.

The present invention has the high-pressure rubber pipe of water cooling plant, and wherein, said bellows is a metal bellows.

After adopting such scheme; The present invention has the high-pressure rubber pipe of water cooling plant owing to outside sebific duct, be with metal bellows; Between sebific duct and metal bellows, form cooling water chamber, therefore in cooling water chamber, inject cooling water, can sebific duct and hot environment be separated; The assurance sebific duct is worked under normal temperature, increases the service life.
