Description

Liquid-resistant test device for O-shaped ring

Technical Field

The utility model relates to the field of liquid resistance tests of O-shaped rings, in particular to a liquid resistance test device for an O-shaped ring.

Background

As is well known, the O-shaped rubber sealing ring is simple to manufacture, convenient to install, reliable in sealing, low in cost, wide in application range and small in friction force to mutually connected parts, so that the O-shaped rubber sealing ring becomes the earliest, the largest and the most common sealing element, is widely applied to sealing structures of mechanical engineering and plays an important role in various fields of national economy. However, the direct consequence of the failure of the rubber seal is leakage of the sealing fluid, which in some cases results in waste of energy or resources and environmental pollution, and in other cases results in failure of the mechanical equipment handling, even explosion and fire. Therefore, the performance and quality control of the O-shaped rubber ring are very important. The liquid resistance is a key index for measuring the rubber performance, and the test is to put a rubber sample into a certain amount of liquid, soak the rubber sample for a certain time at a specified test temperature and take the rubber sample out, and evaluate the adaptability of the rubber material to sealing fluid by measuring the changes of parameters such as mass, volume, hardness, tensile property and the like before and after the rubber material resists the liquid. In order to make the liquid-proof result more meaningful in practical application, the liquid-proof test sample is preferably an O-ring sample, and the standard requires that at least 3-5 parallel samples are made of one sample.

The current liquid-proof test device is a group of stainless steel sleeves with supports, the diameter of each sleeve is too small, each sleeve can only contain one sample, and the sample with larger size cannot be contained, so that the test of various samples is difficult to meet. The liquid resistance test is usually carried out by placing a test device in a high-temperature oven, and some liquid (such as transmission oil) can give off pungent smell in the test process, so that the potential health safety hazard exists. After the test is finished, the sample is required to be taken out as soon as possible for cleaning, but the temperature of the test device is too high, the quality is large, the rapid taking-out operation is not facilitated, and liquid is easy to spill and leak during sampling. In addition, after a long-time high-temperature test, the test liquid may deteriorate and adhere to the inner wall of the sleeve, and the diameter of the sleeve is small, so that certain difficulty is brought to cleaning work.
