Dual-purpose multi-model valve tightness detection pressing device

Abstract

The invention provides a dual-purpose multi-model valve tightness detection pressing device, wherein an upper sealing bench is arranged at the top of a workbench, supporting upright posts are arrangedon two sides of the top of the workbench, the tops of the two supporting upright posts are fixedly connected with a fixed cross rod, the upper sealing bench connected with two pneumatic telescopic rods through a positioning telescopic rod is arranged below the fixed cross rod, sliding chutes are arranged in the two supporting upright posts, a first electric telescopic rod is fixed at the top endof the each sliding chute, a sliding block is arranged at the bottom end of the each first electric telescopic rod, the sliding block is connected with a second electric telescopic rod, a motor grooveis arranged at the tail end of the second electric telescopic rod, the motor groove is connected with a transition groove, a rotating rod is arranged in the transition groove, the tail end of the rotating rod is fixedly connected with a connecting rod, the tail end of the connecting rod is provided with a clamping piece. Through adoption of the dual-purpose multi-model valve tightness detection pressing device, valve tightness pressing operation can be performed on valves of different models, and the clamping piece is used for fixing the position of the valve to be pressed, thus the valve isprevented from being displaced in the pressing process.

Description

technical field [0001] The invention belongs to the technical field of valve airtightness detection equipment, and in particular relates to a dual-purpose multi-type valve airtightness detection and pressing device. Background technique [0002] The valve is an opening and closing switch of an air circuit or a water circuit. It is mainly used to cut off, distribute and change the flow direction of the medium. It needs to be tested for sealing before leaving the factory, otherwise there will be a greater safety hazard during use. The existing When testing the valve, the gasket or sealing ring is usually placed on the outside of both ends of the valve, and at the same time, the two ends of the valve are clamped with a force device such as a jack or a hydraulic cylinder, so that the gasket or sealing ring is in contact with the two ends of the valve. To form a seal, immerse the entire sealed valve in water, and then pass compressed gas into the valve to test its sealing perform...

Problems solved by technology

However, although it simplifies the support operation during valve detection, it still only supports one detection method, and the airtightness of different ends of the valve may be different, so it is necessary to perform two detections on the same valve. , usually requires people to manually change the direction, which requires re-installation of the valve, the process is complicated, and it brings a lot of inconvenience to the detection
