Waterproof sealing device for cement hydration heat test

Abstract

The invention relates to a waterproof sealing device for a cement hydration heat test. The waterproof sealing device comprises a wide-opening thermos bottle, a copper pipe and a cork stopper, wherein a silicon seal is sleeved at an adaptation position outside the opening of the wide-opening thermos bottle; the cork stopper is plugged in the opening; a fastening piece of which the outer ring is provided with threads is sleeved at the exterior of the silicon seal; the fastening piece is connected with a gland outside the fastening piece by virtue of the threads; a rubber stopper with the copper pipe is inserted in the upper port boss of the gland; and the rubber stopper props against the upper end of the cork stopper. The waterproof sealing device can be used for solving the problem that the cork stopper and the wide-opening thermos bottle are difficult to seal, and achieving a favorable waterproof sealing effect; and in addition, all the components of the waterproof sealing device can be subjected to cyclic utilization and are long in service life, so that while a water bath tank liquor environment is protected, resources are saved, and great convenience is brought to users.

Description

technical field [0001] The invention relates to a sealing device, in particular to a waterproof sealing device used for direct cement hydration heat testing, and belongs to the field of cement hydration heat testing. Background technique [0002] When using the direct method cement hydration heat tester to test the heat of cement hydration, paraffin was used to seal the joint between the wide-mouth thermos bottle and the cork. Long-term immersion in the liquid in the bath will partially separate the paraffin from the wide-mouth thermos, causing the liquid in the constant temperature water bath to enter the wide-mouth thermos. When other sealing materials are used for sealing, the ideal effect is not achieved. On the one hand, it affects The heat release of cement hydration is tested. On the other hand, paraffin debris enters the constant temperature water bath, causing pollution to the internal water environment. Contents of the invention [0003] The present invention i...
