Hydrostatic test water tank and hydrostatic test system

Abstract

The embodiment of the invention provides a hydrostatic test water tank and a hydrostatic test system, and relates to the technical field of pressure detection. The hydrostatic test water tank provided by the embodiment of the invention comprises a tank body, an installation assembly and a sealing pipe sleeve. The tank body is provided with a containing cavity for containing a tested container and an opening communicated with the containing cavity, and the installation assembly is fixedly connected with the tank body and located at the opening of the tank body. The two axial ends of the sealing pipe sleeve are fixedly connected with the installation assembly correspondingly, and an installation space communicating with the opening is defined by the inner circumferential face of the sealing pipe sleeve. An inflation gap is formed between the outer circumferential face of the sealing pipe sleeve and the installation assembly, the sealing pipe sleeve deforms due to the pressure change in the inflation gap, in this way, under the condition that the pressure of the inflation gap is increased, and the inner circumferential face of the sealing pipe sleeve is tightly attached to the upper cover through deformation of the sealing pipe sleeve, so the containing cavity is closed to form a closed space. And after use, the upper cover can be detached by releasing the pressure of the inflation gap and recovering the sealing pipe sleeve, so that the test efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of pressure detection, in particular to a hydraulic test water tank and a hydraulic test system. Background technique [0002] A pressure vessel is a closed container that holds gas or liquid and carries a certain pressure. In order to test the pressure bearing strength of the pressure vessel, it is often necessary to carry out a hydrostatic test on the pressure vessel. The hydrostatic test is to place the pressure vessel under test (hereinafter referred to as the test vessel) in a closed water tank filled with water, and then pressurize the test vessel. Part of the water is squeezed out, and the safety of the tested container is detected by measuring the squeezed out water. [0003] However, when the hydraulic test is carried out through the existing device, especially in the case of mass production of the test container, it is necessary to repeatedly open and close and seal the water tank, which not only...
