Drawings
FIG. 1 is a schematic structural view of a flange sealing surface leakage collecting and processing device of the present invention;
in the figure: 1. the high-precision pressure gauge comprises a high-precision pressure gauge 2, a gauge pipe 3, an outer shell sleeve 4, a pipeline 5, an iron strap 6, a gas detection conduit 7, a soft one-way valve 8, a nut 9, a double-headed screw 10, a flange 11, a flange gasket 12 and a one-way valve.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
As shown in FIG. 1, a device for collecting and processing leakage on a flange sealing surface comprises an outer shell 3, a pipeline 4, an iron strap 5, a flange 10, a flange gasket 11, a processing interface and the like. The outer shell 3 is made of corrosion-resistant rubber, the two pipelines 4 are fixedly connected through flanges 10, double-headed screws 9 and nuts, and flange gaskets 11 are arranged between the two flanges 10. The outer shell 3 is sleeved on the pipeline 4 and the flange 10 along the circumferential direction to form a sealed cavity, and two axial sides are respectively fastened by iron strap 5. The outer shell 3 is provided with a processing interface.
The processing interface includes: gas detection pipe 6, check valve 12, high accuracy manometer 1. A soft one-way valve 7 is arranged in the gas detection conduit 6, a cover cap is arranged at the port of the gas detection conduit 6, and the gas detection conduit is in a tightly covered state in non-detection time; when detection is carried out, the cap is opened, and the sampling tube is inserted below a soft one-way valve 7 (which can prevent gas from overflowing after the cap is opened) in the gas detection conduit 6 for gas collection and analysis; when the concentration reaches a certain degree, the air pump is adopted to discharge and treat the leaked air in the cavity, negative pressure is generated in the cavity at the moment, the one-way valve 12 is opened to suck the air outside the cavity into the cavity, and the air replacement in the cavity is formed. High accuracy manometer 1 passes through table pipe 2 and installs at outer shell cover 3, can measure the pressure variation in the cavity, can assist the volume of the gas of leaking in judging the cavity.
When the on-site inspection is carried out, firstly, whether a high-precision pressure gauge exceeds a certain threshold value is checked, if the high-precision pressure gauge exceeds the threshold value, a gas detection guide pipe cover cap is opened, a sampling pipe is inserted below a soft one-way valve, and gas collection and analysis are carried out. After the gas sampling result reaches a certain concentration, the gas in the cavity is confirmed to be replaced, the exhaust pipe is inserted, the air pump is started to exhaust, the one-way valve is opened, and the gas in the cavity is ensured to be replaced thoroughly. After the replacement is completed, the cap is closed tightly.
