AI Technical Summary

Technical Problem

Existing breather valve testing equipment cannot be flipped multiple times in a short period of time to simulate the multiple flips and flipping frequency changes of the storage tank during transportation, resulting in poor testing results.

Method used

A breather valve detection device for atmospheric pressure storage tanks was designed. By setting thread grooves with gradually varying pitch and extrusion blocks, the device simulates the multiple flips and changes in flip frequency of the storage tank during transportation. A piston plate is used to change the pressure inside the placement box to simulate leakage under low pressure conditions. A screw and pawl structure is used to increase centrifugal force. An impact mechanism simulates the collision during the flipping process.

Benefits of technology

It enables comprehensive testing of the breather valve under multiple flips and different pressures, can determine component damage or displacement, simulate leakage during the flipping process, and improves the comprehensiveness and accuracy of the test.

Abstract

The application discloses a kind of atmospheric storage tank breather valve detection equipment, belongs to the technical field of breather valve detection.A kind of atmospheric storage tank breather valve detection equipment, including support frame, rotating frame is rotatably installed on support frame, extrusion cavity is opened in the lower side of rotating frame, drive mechanism is installed in extrusion cavity inside, drive mechanism includes motor installed on support frame, reciprocating screw rod is fixedly installed at motor output end, extrusion block is sleeved on the outside of reciprocating screw rod, the pitch of screw groove gradually decreases from the side close to motor to the other side, two guide rods are provided in extrusion cavity inside.The rotating frequency of rotating frame can be changed by the thread groove with gradually changing pitch, extrusion block and ball cooperation, so that the situation that multiple overturning and overturning frequency change when storage tank falls during transportation can be simulated, so that the situation whether each component inside breather valve will be damaged or deviated when overturning frequency changes can be judged.
