Abstract

The invention relates to the technical field of pipeline connection, in particular to a pipeline flange connecting device and fluid equipment using the same. A pipeline flange connecting device comprises a first supporting part, a second supporting part, a clamping part, a ratchet mechanism, a transmission mechanism and an adjusting mechanism. The first supporting part comprises a first supporting ring frame and a first threaded ring, and the second supporting part and the first supporting part are the same in structure, are oppositely arranged and comprise a second supporting ring frame and a second threaded ring. The clamping part comprises a plurality of clamping plates arranged on the two sides of the flanges of the two pipelines. The adjusting mechanism comprises a plurality of bevel gears, a plurality of handles, an asynchronous mechanism and a switching part. According to the pipeline flange connecting device, the first threaded ring and the second threaded ring are firstly driven to rotate synchronously, so that the two flanges are close to each other, and the first pipeline and the second pipeline are connected. And then one threaded ring is fixed, and the other threaded ring is rotated, so that the flange is clamped more tightly. The fluid equipment using the connecting device is not prone to liquid leakage.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a pipeline flange connection device and fluid equipment using the connection device. Background technique [0002] Flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a set of combined sealing structures. Add a gasket between the two flanges and fasten them with bolts. Different pressure flanges have different thicknesses, and they use different bolts. When bolts are used to fasten the flange, the bolts are not tightened synchronously, which will cause uneven force on the bolted connection on the end face of the flange, affecting the connection stability and sealing performance. [0003] In fluid equipment, especially at the interconnection of high-pressure vessels, when bolts are used to fasten flanges, the bolts are not tightened synchronously, which will cause uneven stress on the ...
