Abstract

The invention relates to a float type exhaust device. The device comprises a pipe connecting flange, a pressure blind plate and a pressure gauge. The device is characterized in that the pipe connecting flange, a cushion and the pressure gauge are fixedly arranged at the flange joint of a to-be-tested container by virtue of fastening bolts; a sealed joint is arranged on the pressure blind plate, is connected with a pressure-resistance hose with a floater in the to-be-tested container, and is connected with an exhaust valve by virtue of a metal tube, outside the to-be-tested container; a testing liquid inlet is formed in the pressure blind plate; and a water inlet valve with a pressure gauge is connected outside of the testing liquid inlet. The invention aims to solve the technical problem of providing the float type air emptying device capable of completely solving the air emptying problem. By utilizing the buoyancy effect of the floater, the floater can reach the top end of the to-be-tested container to achieve the aim of emptying air, and the pressure-resistance hose connected with the floater is good in flexibility and easy to assemble and disassemble. The float type exhaust device is convenient to operate, can be used for saving time and labor, and is low in labor intensity.

Description

technical field [0001] The invention relates to the technical field related to the pressure regulation of a closed container, in particular to a float type exhaust device suitable for a pressurized closed container. And it is suitable for all pressurized airtight container products containing liquid. Background technique [0002] At present, pressure vessel products involve many fields and are widely used in electric power, chemical industry, petroleum, machinery, metallurgy, nuclear energy, aviation, aerospace and other departments, and are indispensable core equipment in the production process. Evacuating the gas in the container can change the gas-liquid space of the container into a liquid space, which greatly improves the safety of operation, reduces the possibility of accidents, avoids the danger caused by the mixing of gas and liquid in the container, and reduces the pressure given by the gas-liquid space. The corrosion caused by the container improves the safety and...
