Multi-station ball-valve bursting test machine

Abstract

The invention discloses a multi-work station ball valve blasting testing machine which belongs to the field of testing device. The testing machine comprises a testing host and a control cabinet. The testing host is divided into two layers; a testing table is arranged on the upper layer and a machine base is arranged on the lower layers. The testing table is provided with 3 to 10 testing work stations which are arranged in parallel and which can simultaneously test the pressure and blasting performance of 1 to 10 ball valves. In the test, hydraulic oil uses a solenoid directional control valve to push each piston; the compression rod of each piston can rise simultaneously; a special sealing fixture is used for sealing and clamping two ends of the ball valve. A hydraulic test pump is used for pouring the testing medium into the tested ball valve and boosting the pressure of the tested ball valve so as to test the ball valve. The testing machine can simultaneously seal, clamp, pour the testing medium into and test a plurality of ball valves. In the whole test process, a computer is used for automatically controlling the test through a PLC controller. And the testing machine has the advantages of stable performance, high work efficiency, low labor intensity, simple structure, high security, and so on.

Description

technical field

[0001] The invention relates to a burst testing machine for a multi-station ball valve. Background technique

[0002] The ball valve has to bear a certain pressure during work. Because it works under pressure for a long time, its pressure resistance will directly affect the service life of the ball valve. At the same time, the instantaneous pressure of the ball valve is too high to cause explosion. Once the valve bursts , It will not only threaten the life safety of the operators but also cause losses to the property of the enterprise. In order to ensure the safe use of ball valve products, it is necessary to test the blasting performance of the ball valve in time to ensure the factory pass rate of the ball valve and prevent problems before they happen.

[0003] For a long time, the test items of ball valves have been pressure tests aimed at sealing performance and shell strength, and it is impossible to formulate the pressure limit of ball valves. At prese...
