Abstract

The invention discloses a valve pressure tester for a pipeline. The tester comprises a fixed pedestal, a valve fastening mechanism, a stable elevating mechanism and a test protection mechanism; the valve fastening mechanism comprises a positioning vertical plate welded to one side of the top of the fixed pedestal, a push rod motor is mounted in the external end surface of the positioning verticalplate, the internal end surface of the positioning vertical plate is connected two supporting cross bar and fixing cross bar groups, one end of each fixing cross bar is rotationally provided with an adjusting long rod, one end of the adjusting long rod is welded to a valve clamping plate, one end of each supporting cross bar is rotationally provided with a first gear, the top edge position of thefirst gear is rotationally provided with a swing rod, one end of the swing rod is rotationally connected with the adjusting long rod, and the first gear drives the swing rod and the adjusting long rodto swing left and right in the rotation process. Thus, valves of different specification can be fixed rapidly and undergo pressure test, the valves are protected against damage and deformation in valve pressure test process, and the valve using quality and testing efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve pressure testing device for pipelines. Background technique [0002] In the process of valve production, testing and maintenance, the pressure test that the valve can withstand is an important process. The valve pressure test device is an indispensable equipment for all kinds of factories that produce valves. Before the valve leaves the factory or is used by the user It needs to be tested for pressure. [0003] The pressure test of the valve is generally completed by the manufacturer. Before the valve leaves the factory, use the valve pressure equipment to carry out the pressure test on the valve to confirm that the valve has no internal leakage, and the valve body has no defects such as micropores and cracks, and check that the pressure resistance of the valve meets the design requirements. However, valves will still leak internally after being used for a period of time,...
