Description

Technical Field

[0001] The invention belongs to the technical field of motor valves, and in particular relates to a motor valve sealing detection device. Background Art

[0002] Motor valve, usually refers to electric valve, is a valve that uses an electric device to control the flow of fluid (such as water, gas, oil, etc.). In order to ensure that the motor valve can work stably during use, it is necessary to test the sealing performance of the motor valve to prevent leakage when the motor valve is closed.

[0003] When testing the sealing of the three-way motor valve, since the three-way motor valve has three channels, the prior art needs to block one of the channels, introduce gas into another channel, and then put the detection device into the remaining channel to detect the sealing of the remaining channel, and then block the other unblocked channels in turn to detect the sealing of different channels. However, this method has complicated steps and low detection efficiency. In addition, the three channels of the three-way motor valve are arranged differently according to specific needs. When testing the sealing of the three-way motor valves with different arrangements, in order to facilitate detection, different operating tables need to be replaced to adapt to different three-way motor valves, which greatly reduces the work efficiency of the inspectors.

Different three-way motor valves can be clamped and fixed, which is convenient for stable detection of the sealing of the three-way motor valve.

[0038] The operating principle of the present invention is now described as follows:

[0039] In the present invention, when it is necessary to detect the sealing performance of the three-way motor valve, the first motor 102 and the second motor 105 are first controlled to start, and the first circular gear 103 and the second circular gear 106 are driven to rotate, thereby driving the first gear 101 and the second gear 104 to rotate. During the rotation of the first gear 101 and the second gear 104, the first rotating ring 4 and the second rotating ring 7 are driven to rotate. By adjusting the rotation direction of the first motor 102 and the second motor 105, it is ensured that the first connecting plate 5 and the second connecting plate 8 do not cross each other. By driving the first connecting plate 5 and the second connecting plate 8 to rotate, the positions of the first connecting plate 5 and the second connecting plate 8 correspond to the two main channels of the three-way motor valve. Then, the three-way motor 102 is controlled by the inspector to rotate the first connecting plate 5 and the second connecting plate 8. The valve is placed on the upper surface of the support plate 1, so that one end of the two main channels corresponds to the first connecting plate 5 and the second connecting plate 8 respectively. When the three channels of the three-way motor valve are distributed in a ring shape, at this time, on the basis that the position of the secondary channel corresponds to the first side plate 115, the first connecting plate 5 and the second connecting plate 8 are controlled to correspond to the positions of the two main channels. After the positions of the first side plate 115, the first connecting plate 5 and the second connecting plate 8 correspond to the positions of the three channels of the three-way motor valve, the first electric telescopic rod 91 and the fourth electric telescopic rod 111 are controlled to extend, respectively driving the support plate 92 and the first side plate 115 to move upward, so that the first detection shell 95 and the second detection shell 118 can correspond to the three channel openings of the three-way motor valve, and then the second electric telescopic rod 91 and the fourth electric telescopic rod 111 are controlled to extend, and the support plate 92 and the first side plate 115 are respectively driven to move upward, so that the first detection shell 95 and the second detection shell 118 can correspond to the three channel openings of the three-way motor valve. 94 and the fifth electric telescopic rod 117 are started, driving the first detection shell 95 and the second detection shell 118 to move toward the three channels of the three-way motor valve, so that the first annular bayonet 96 and the second bayonet opened on the side walls of the first detection shell 95 and the second detection shell 118 are in contact with the side walls of the three channels respectively, and the first sealing gasket 97 and the second sealing gasket 1110 are used to seal the first detection shell 95, the second detection shell 118 and the three channels. Then, one of the first air pumps 911 is controlled to start to inject external air into the main channel, and then the seventh electric telescopic rod 1111 and the third electric telescopic rod 98 are controlled to start to drive the first detection plate 99 and the second detection plate 1112 to move toward the inside of the channel. When the first pressure sensor 910 Or after the second pressure sensor 1113 detects the pressure, it means that this channel is leaking and the sealing is low, then the other unstarted first air pump 911 or the second air pump 1114 is controlled to start in turn, and air is injected into different channels in turn, and the corresponding first detection plate 99 or the second detection plate 1112 in the other two channels are extended to detect the sealing in their channels. When the secondary channel of the three-way motor valve to be detected is vertically downward, the position of the first detection shell 95 is adjusted to correspond to the two main channel positions of the three-way motor valve, and the sixth electric telescopic rod 114 is controlled to start, driving the second detection shell 118 to move upward, so that the side wall of the second annular bayonet 119 opened on the side wall of the second detection shell 118 contacts the side wall of the secondary channel.The second sealing gasket 1110 is used to ensure the sealing of the second detection shell 118 and the secondary channel. After that, the first detection shell 95 is adjusted according to the above steps, and the sealing of the three-way motor valve is tested. It can accurately detect whether the internal sealing of the three channels of the three-way motor valve is good, and the position of the first detection shell 95 can be adjusted according to the position of the main channel of the three-way motor valve, so as to facilitate the blocking of the three channels of the three-way motor valve at different angles, and realize the rapid detection of the sealing of the three-way motor valve. At the same time, the sealing of the three-way motor valves distributed in an annular manner in the three channels and the three-way motor valves vertically downward in the secondary channel can be tested, so as to avoid the staff from replacing the adaptable operating table according to different three-way motor valves, reducing the detection efficiency, and improving the efficiency and adaptability of the equipment in the sealing detection of the three-way motor valve.
