[0014] A clamp-type flange leakage monitoring device

[0015] like figure 1 , figure 2 , image 3 Shown: the clamp-type flange leakage monitoring device includes an upper leak-testing cavity 5 and a lower leak-testing cavity 11 . The flange connection system consists of the left pipe 1, the left flange 3, the gasket 6, the right flange 7, the right pipe 8, and under the action of the fastening bolt 4, a closed connection system is formed for the medium to flow in it, such as figure 1 shown in the dashed line. The upper leak detection cavity 5 and the lower leak detection cavity 11 are closed at the periphery of the flange connection system to monitor the leakage condition of the flange. The left side of the upper leak-testing cavity 5 is provided with pin holes, and the side of the lower leak-testing cavity 11 corresponding to the upper leak-testing cavity 5 is also provided with a pin hole complementary to the upper leak-testing cavity 5. The leak testing cavity 5 and t...

Abstract

The invention discloses a clamp-type flange leakage monitoring device, which comprises an upper leakage detection cavity and a lower leakage detection cavity. A flange connection system is a closed connection system formed by a left pipeline, a left flange, a gasket, a right flange and a right pipeline under effects of fastening bolts for enabling a medium to flow inside, and the upper leakage detection cavity and the lower leakage detection cavity are closed on the periphery of the flange connection system for monitoring the leakage condition of the flange. The left side of the upper leakage detection cavity is provided with a pin hole; one side, corresponding to the upper leakage detection cavity, of the lower leakage detection cavity is also provided with a pin hole complementary with the upper leakage detection cavity; the upper leakage detection cavity and the lower leakage detection cavity are connected through a pin; the upper leakage detection cavity and the lower leakage detection cavity can rotate up and down around the pin; the right side of the upper leakage detection cavity is provided with an upper leakage detection cavity extending plate; the upper leakage detection cavity extending plate and the upper leakage detection cavity are as a whole; and the upper leakage detection cavity extending plate is provided with a bolt hole.

Description

technical field [0001] The invention belongs to the field of leakage monitoring, and in particular relates to a clamp type flange leakage monitoring device. Background technique [0002] Flanges are widely used in petroleum, chemical, pharmaceutical, energy and electric power industries because of their advantages of easy installation and disassembly. Leakage occurs due to reasons. In recent years, chemical plant explosion accidents and oil and gas pipeline leakage have been frequently reported, and a large proportion of leakage accidents are related to flange leakage. Even a small number of nuclear power plant installation failures are caused by flange leakage. The method of using personnel to continuously inspect many flange connections in the factory area and workshop has the weakness of low sensitivity, and sudden leakage accidents may endanger the lives of relevant personnel. The leakage of toxic, harmful, radioactive and flammable and explosive media often brings se...
