Problems solved by technology

[0003] The existing ball valve sealing performance testing device needs to place the ball valves one by one on the testing equipment, and then press the detection button, the telescopic rod moves down to compress and seal the two ends of the ball valve, the inflatable equipment is inflated, and the device switch is turned The valve knob is used to test the tightness of the invention. The test takes more than ten seconds. After the test is completed, the telescopic rod is lifted up and the rotating device is released. At this time, the worker removes the ball valve and puts the next ball valve to be tested. Press the button to start the test, so The operation and detection efficiency is low, which greatly increases the labor cost. Therefore, we propose a ball valve sealing performance detection device and method that can be judged by gas pressure

Abstract

The invention discloses a ball valve sealing performance detection device and method capable of being judged through gas pressure intensity, relates to the field of ball valve sealing performance detection, and solves the problems that when an existing ball valve sealing performance detection device capable of being judged through gas pressure intensity is used, manual feeding and discharging are time-consuming and labor-consuming, and the efficiency is low. Comprising a machine body, a storage device and a discharging device, the machine body is provided with a plurality of sets of detection bases and lifting inflation detection equipment, the machine body is fixedly connected with a telescopic rod, the telescopic end of the telescopic rod is fixedly connected with a push-pull rod, the push-pull rod is provided with a plurality of sets of grabbing devices used for grabbing ball valves, and qualified products and unqualified products are stored separately. According to the ball valve sealing performance detection device capable of being judged through the gas pressure, by arranging the grabbing device, the storage device and the discharging device, batch storage and automatic batch detection can be conveniently carried out on to-be-detected ball valves, meanwhile, qualified products and unqualified products of the detected ball valves can be stored separately, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ball valve sealing performance detection, in particular to a ball valve sealing performance detection device and method which can be judged by gas pressure. Background technique [0002] With the rapid development of the national economy, the demand for valves from all walks of life is increasing, and the performance requirements are increasing. In addition, the export of valves is also increasing, and the demand for Chinese valves in other countries is increasing. Especially the demand for ball valves, including conventional ball valves, ultra-low temperature ball valves, high-temperature hard-sealed ball valves, anti-corrosion ball valves sealed with polymer materials, etc., has a large demand, and the requirements are very high. The anti-corrosion of conventional ball valves and polymer materials Ball valves must have zero internal leakage, and ultra-low temperature ball valves and high-temperature har...
