Abstract

The invention provides a creep tester for sealing gasket materials under a high temperature, wherein upper and lower ends of the to-be-detected sealing materials are separately provided with an upper pressing plate and a lower pressing plate which are fixed through a pressurizing nut, an inner wall of a hollow bolt is vertically connected with a positioning mandrel, a bottom end of the positioning mandrel is fixed on the hollow bolt through a fixed rivet, a top end of the positioning mandrel is close to a measure meter of a dial gauge, the measure meter of the dial gauge is connected with a dial plate of the measuring dial gauge through a frame of the dial gauge, and through a fix sleeve of the dial gauge, the frame of the dial gauge is fixed on a top of the hollow bolt and by a stop bolt. The tester provided by the invention is simple in structure, convenient to operate and accurate in measurement.

Description

technical field [0001] The invention relates to a tester, in particular to a high-temperature creep tester for gasket materials. Background technique [0002] At present, the high-temperature creep testers used in China are all imported equipment, the equipment structure is complex, and the price is high. This invention uses variable bolts, dial gauges, and temperature control boxes to complete the sealing material high temperature (90°C) required by the national standard. ) The task of accurate measurement of creep amount. Contents of the invention [0003] The object of the present invention is to provide a high-temperature creep tester for gasket materials with simple structure, convenient operation and accurate measurement. The tester can accurately measure the creep amount of sealing materials at high temperatures (90°C) required by national standards. Task. [0004] The present invention is realized like this, and it comprises dial gauge dial for measuring, dial ga...
