Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of petroleum chemical industry protection, specifically relates to a kind of petroleum chemical processing explosion-proof protection device. BACKGROUND

[0002] In the field of petroleum chemical processing, pipeline transportation is widely used in various production links as a key material conveying method. Since most petroleum chemical products are flammable and explosive, it is crucial to ensure the safe operation of the pipeline system. As a weak link in the entire pipeline system, the pipeline connection is faced with many potential risks.

[0003] During long-term use of the pipeline, the connection is prone to aging and wear of the sealing element due to factors such as material scouring, temperature changes, and pressure fluctuations, resulting in leakage. Once the flammable and explosive material leaks and comes into contact with a fire source in the surrounding environment, it is highly likely to cause an explosion, causing serious damage to personnel safety, production facilities, and the surrounding environment. Therefore, a petroleum chemical processing explosion-proof protection device is proposed. SUMMARY

[0004] The utility model aims to provide a kind of petroleum chemical processing explosion-proof protection device to solve the problems raised in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides a kind of petroleum chemical processing explosion-proof protection device, which comprises a first oil pipeline and a second oil pipeline. The outer side of the first oil pipeline is fixedly connected with a first flange near the bottom end. The outer side of the second oil pipeline is fixedly connected with a second flange near the top end. A sealing ring is arranged between the first flange and the second flange. The first oil pipeline and the second oil pipeline are connected through the first flange and the second flange. A protection assembly is arranged on the outer side of the first oil pipeline and the second oil pipeline. The protection assembly comprises two semicircular shells. The two semicircular shells are located on the outer side of the first oil pipeline and the second oil pipeline. A semicircular clamping ring is fixedly connected to the inner wall of the top side of the two semicircular shells. Two semicircular clamping shells are arranged in the two semicircular shells. A semicircular connecting pipe is fixedly connected to the bottom side of the semicircular clamping shell. A seminut is fixedly connected to the bottom end of the semicircular connecting pipe.

[0006] As a further improvement of the present technical solution, two fixed metal strips are fixedly connected to the outer side of the semicircular shell. The two fixed metal strips are symmetrically arranged. The two semicircular shells are fixedly installed on the outer side of the first oil pipeline and the second oil pipeline through the two fixed metal strips arranged on the outer side of the semicircular shell.

[0007] As a further improvement of the technical solution, the bottom side of the semicircular clamping ring is fixedly connected with a semicircular sealing strip, and when the two semicircular clamping shells extrude the two semicircular sealing strips, the two semicircular clamping shells are in sealing contact with the bottom side of the two semicircular clamping rings.

[0008] As a further improvement of the technical solution, a threaded groove is formed in the inner wall of the semicircular shell near the bottom side, and a threaded strip is fixedly connected to the outer side of the semicircular connecting pipe, and the threaded groove is matched with the threaded strip.

[0009] As a further improvement of the technical solution, the two semicircular shells are in sealing contact with the first oil pipeline, and the two semicircular shells are in sealing contact.

[0010] As a further improvement of the technical solution, by rotating the two semicircular nuts to drive the two threaded strips to move vertically upward, the two threaded strips drive the two semicircular clamping shells to move vertically, so that the two semicircular clamping shells extrude the two semicircular clamping rings, and the two semicircular clamping shells are in sealing contact with the two semicircular clamping rings.

[0011] Compared with the prior art, the utility model has the advantages of:

[0012] In the explosion-proof protection device for petroleum chemical processing, the two semicircular shells can protect the pipeline connection, avoid the aging and damage of the sealing ring in harsh environment, and through the rotation of the two seminuts to drive the two semicircular connecting pipes to move vertically upward, the two semicircular connecting pipes drive the two semicircular clamping shells to move vertically, so that the two semicircular clamping shells extrude the two semicircular clamping rings, and the two semicircular clamping shells are in sealing contact with the two semicircular clamping rings, so that the connection can be sealed twice, and the sealing ring of the connection can be protected, so that the sealing ring is not easy to be damaged, and the leakage phenomenon is reduced, so that the safety of personnel can be ensured.
