Description

Technical Field

[0001] The utility model belongs to the technical field of finished stop valve detection, in particular to a detection platform for processing stop valves. Background Art

[0002] The stop valve is a tool that relies on the pressure of the valve stem to make the valve disc sealing surface fit tightly with the valve seat sealing surface to prevent the flow of medium. It is a forced sealing valve and is mainly installed on high-temperature and high-pressure steam and water pipelines with a diameter of ≤100mm in the power plant piping system.

[0003] The inner diameter of the stop valve is particularly important for the sealing of the pipeline system. However, most manufacturers currently test the stop valve based on the outside of the stop valve and often ignore the inner diameter test, which will result in unqualified products being released into the market.

[0021] like Figures 1-4 As shown, a detection platform for stop valve processing consists of a telescopic electric cylinder 1, a carrying cylinder 2, an inspection component 3, a support plate 4, a quality inspection platform 5, a displacement device 6, a displacement plate 7, a displacement electric cylinder 8, a recovery channel 9, a pushing electric cylinder 10, a dotting component 11, a camera 12, a focusing ring 13, a retaining ring 14, a support frame 15, a control electric cylinder 16, a dotting plate 17, a concave block 18, a push plate 19, and a detection needle 20.

[0022] A detection device is provided on the quality inspection table 5, a dotting assembly 11 is provided on the side of the detection device, a feeding channel is provided between the detection device and the dotting assembly 11, a visual inspection assembly 3 is provided on the side of the dotting assembly 11, and the tail end of the detection device is connected to the carrying cylinder 2 through a connecting channel;

[0023] The detection device includes a displacement cylinder 8, a displacement plate 7, a support plate 4, a telescopic cylinder 1, a push plate 19 and several detection needles 20. The displacement cylinder 8 is arranged on the quality inspection table 5, the displacement plate 7 is transmission connected to the output end of the displacement cylinder 8, the support plate 4 is fixedly connected to the displacement plate 7 through a pillar, the telescopic cylinder 1 is arranged on the support plate 4, the push plate 19 is transmission connected to the output end of the telescopic cylinder 1, and the detection needles 20 are evenly arranged on the push plate 19.

[0024] A concave block 18 for supporting the stop valve is provided on the feeding channel, and one side of the concave block 18 is opposite to the detection needle 20 .

[0025] The dotting assembly 11 includes a fixed frame, a pushing electric cylinder 10, a control electric cylinder 16, a dotting plate 17 and a cross frame.

If it meets the factory requirements, it continues to move to the tail end of the upper feeding channel. The surface of the stop valve is inspected by the visual inspection assembly 3. After confirming that the surface is free of defects, it is uniformly recovered by the carrier cylinder 2.
