Rubber diaphragm sealing performance detection device

Abstract

The invention relates to the technical field of rubber diaphragm production and processing equipment, and discloses a rubber diaphragm sealing performance detection device which comprises an operation table, an air guide pump and a detection box, an air guide chamber and an air storage chamber are formed on the operation table, the air guide chamber is of an open structure, and the rubber diaphragm can cover the open end of the air guide chamber. A first gas guide pipe is connected between the gas storage chamber and the gas guide chamber, and a second gas guide pipe is connected between the gas storage chamber and the detection box; a detection area, an observation area and a swing rod are arranged in the detection box, a detection block is installed at the end, arranged in the detection area, of the swing rod, and a swing ball is installed at the end, arranged in the observation area, of the swing rod. If the rubber diaphragm has a leak, gas can be guided into the gas guide chamber through the leak through the gas guide pump and impacts the detection block in the detection area through the gas storage chamber to drive the swing ball to swing, so that the sealing performance of the rubber diaphragm is relatively accurately judged.

Description

technical field [0001] The invention relates to the technical field of rubber diaphragm production and processing equipment, in particular to a rubber diaphragm sealing performance detection device. Background technique [0002] Rubber diaphragms are mainly used in valves, regulating valves, automatic mechanical follow-up devices, switches and counters for flow, pressure, differential, liquid level, constant temperature volume heat compensation, etc., mainly made of rubber materials, according to the structure and shape It is divided into flat diaphragm, corrugated diaphragm, disc diaphragm and rolling diaphragm, which have the advantages of heat resistance, medium resistance, pressure resistance, flex resistance, sensitivity, good compounding, and long working life. [0003] As a common sealing part in mechanical equipment, rubber diaphragm is very important to the performance and service life of mechanical equipment. Therefore, before the rubber diaphragm leaves the factor...

AI Technical Summary

Problems solved by technology

[0004] At present, the air tightness detection of rubber diaphragms usually adopts the method of manual manual inspection, which relies on manual experience for detection, which is highly accidental and cannot guarantee the accuracy of the detection. The detection accuracy is low. For rubber with small loopholes The diaphragm cannot be detected accurately, which affects the quality of the factory rubber diaphragm
