[0002] Steel flange suction and discharge hoses are widely used in oil field development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, heavy machinery, agricultural machinery, various machine tools, and mechanization of various industrial sectors. In these fields, steel flange suction and discharge hoses play an important role as important fluid transmission and connection components.

[0003] Existing steel flange suction and discharge hoses have insufficient sealing, which causes leakage of media during transmission. This leakage not only means ineffective consumption and waste of resources, but is also more likely to cause irreversible pollution to the environment. In addition, leakage will significantly reduce the overall efficiency of the conveying system because the leaked media cannot effectively reach the destination, thus affecting the smooth progress of the entire production or workflow.

DETAILED DESCRIPTION

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] As attached Figure 1 To Attachment Figure 5 As shown: This embodiment provides a steel flange suction and discharge hose, including: a hose body 1, and also includes:

[0023] Steel flanges 2, which are fixedly mounted on both ends of the hose body 1;

[0024] The sealing mechanism 3 is arranged at the connection end of the steel flange 2 to increase the sealing performance.

[0025] Specifically, the hose body 1 consists of an inner rubber layer 101, a reinforcement layer 102, a middle rubber layer 103 and an outer rubber layer 104. The inner rubber layer 101 is in contact with the conveying medium, the reinforcement layer 102 is located between the inner rubber layer 101 and the outer rubber layer 104, and the middle rubber layer 103 is arranged between the inner rubber layer 101 and the reinforcement layer 102.

[0026] In this embodiment: the hose body 1 serves as the main channel for conveying the medium, and is composed of an inner rubber layer 101, a reinforcement layer 102, a middle rubber layer 103 and an outer rubber layer 104, wherein the inner rubber layer 101 is in direct contact with the conveying medium, providing basic sealing and corrosion resistance, the reinforcement layer 102 increases the compressive strength and durability of the hose, the middle rubber layer 103 is located between the inner rubber layer 101 and the reinforcement layer 102, and may play a buffering and protective role, and the outer rubber layer 104 provides external protection and wear resistance.

[0027] Specifically, the inner surface of the inner rubber layer 101 is provided with a corrosion-resistant layer 4, the surface of the outer rubber layer 104 is provided with a wear-resistant layer 5, the reinforcing layer 102 is made of a spiral steel wire skeleton, the corrosion-resistant layer 4 is made of polyurethane, and the wear-resistant layer 5 is made of epoxy resin composite material coating.

[0028] In this embodiment: the polyurethane material has excellent corrosion resistance and can resist erosion by a variety of chemical substances. This allows the polyurethane to be used as the corrosion-resistant layer 4 to effectively protect the inner rubber layer 101 of the hose body 1 from corrosive media and extend the service life of the hose. At the same time, the polyurethane material has strong resistance to oils and solvents, and can maintain the stability of its physical and chemical properties even when in contact with oils or solvents for a long time. This is especially important for hoses that transport oily media or need to contact solvents. The epoxy resin composite material coating has extremely high wear resistance and can effectively resist wear and friction in the external environment, protecting the outer rubber layer 104 of the hose body 1 from damage. At the same time, the epoxy resin composite material coating has good adhesion to the rubber substrate, which can ensure that the coating is not easy to fall off during long-term use and maintain a lasting protective effect.

[0029] Specifically, a screw rod 6 is inserted into the through hole on the surface of the steel flange 2 , and a gasket 7 is sleeved on the outer side of the screw rod 6 .

[0030] In this embodiment, the screw 6 and the gasket 7 cooperate to achieve a tight connection between the steel flange 2 and other equipment or pipelines, thereby ensuring the tightness and stability of the connection and preventing leakage of the medium.

[0031] Specifically, the sealing mechanism 3 includes an insert rod 301 fixedly installed on the connecting end of the steel flange 2. The insert rod 301 is a hollow structure. A sealing rubber sheet 302 is sleeved on the outer side of the insert rod 301. An installation groove 303 is opened on the outer side of the insert rod 301. A sealing ring 304 is sleeved inside the installation groove 303.

[0032] In this embodiment: by setting the sealing mechanism 3, the sealing performance of the connection end of the steel flange 2 can be increased to prevent leakage of the medium. The hollow structure of the plug rod 301 may be used to accommodate the medium or serve as a guide during connection. The mounting groove 303 is used to fix and position the sealing ring 304. The sealing rubber sheet 302 and the sealing ring 304 provide an additional sealing layer to ensure that the medium will not leak from the connection.

[0033] The working principle and use process of this utility model:

[0034] The steel flange 2 is fastened to other equipment or pipelines through screws 6 and gaskets 7. At this time, the plug rod 301 of the sealing mechanism 3 is inserted into the corresponding connection end, and the sealing rubber sheet 302 and the sealing ring 304 are tightly fitted with the connection end to ensure the sealing. When the medium needs to be transported, the medium flows through the inner rubber layer 101 of the hose body 1. The polyurethane material of the corrosion-resistant layer 4 can effectively resist the erosion of the medium and protect the inner rubber layer 101. At the same time, the wear-resistant layer 5 of the outer rubber layer 104 can resist the wear and friction of the external environment and protect the external structure of the hose body 1.
