Description

Technical Field

[0001] The utility model relates to the technical field of rubber detection, in particular to a device for detecting the service life of a rubber bushing of a pipe clamp valve. Background Technique

[0002] The rubber bushing of the pipe clamp valve is a rubber hose.

[0003] However, the existing detection of the service life of rubber hoses includes tensile resistance detection. During the tensile resistance process of the rubber hose, cracks on the surface of the rubber hose are detected. However, during the detection process of the rubber hose, when the two ends of the rubber hose are fixedly clamped, the two ends of the rubber hose are usually flattened, causing the two ends of the rubber hose to fold. The folding part of the rubber hose has poor tensile resistance, affecting the detection effect of the rubber hose. For this reason, we propose a device for detecting the service life of a rubber bushing of a pipe clamp valve. Content of the Utility Model
