DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-4As shown, a valve air tightness detection device proposed in an embodiment of the utility model includes a base 1 and a driving member 2. The valve air tightness detection device designed in this scheme can realize convenient adjustment and applicability when detecting valves of various sizes, and can improve the convenience of valve detection and replacement, and improve the connection rate. The base 1 is fixedly connected with the driving member 2, and a plurality of resistance members 3 are arranged in a ring array on the driving member 2. The base 1 is symmetrically provided with sealing plugging members 4, and the sealing plugging members 4 are connected and arranged in cooperation with the detection member 5. The resistance member 3 is composed of a resistance block 301, a plug rod 302, a spring 303 and a pull plate 304. The resistance block 301 is fixedly connected with the plug rod 302, and the plug rod 302 is sleeved with a spring 303. The end is fixedly connected with a pull plate 304, and the pull plate 304 is fixedly connected to one end of the spring 303. The device is electrically connected to an external control device through a conductive line, and the operating state of the device is controlled by the external control device. When the valve is detected, the pull plate 304 is pulled to make the plug rod 302 slide and plug in the plug hole 205. Since the resistance block 301 is slidably connected in the adjustment groove 203 and the limiting slide groove 204, when the pull plate 304 is pulled, the resistance block 301 will slide horizontally on the driving disk 202 for adjustment. Since one end of the spring 303 is fixedly connected to the pull plate 304, and the other end is fixedly connected to the driving disk 202, when the pull plate 304 is pulled, the spring 303 will extend and maintain the rebound force. At this time, The valve is placed in the adjusting groove 203, and then the pull plate 304 is released. The spring 303 rebounds to make the abutment block 301 abut against the valve, so that the valve is abutted between the abutment block 301 and the driving disk 202, meeting the fixed use requirements. The driving disk 202 can be driven to rotate by the motor 201, so that the several valves on the driving disk 202 can be moved one by one between the two detection parts 5 for detection. When the valve is between the two detection parts 5, the piston rod of the cylinder 404 is extended to make the abutment disk 502 abut against the port of the valve, thereby forming a seal on the valve port. One end of the air supply pipe 503 is at the center of the abutment disk 502, and is connected to the external air supply machine through the air supply pipe 503 to supply air to the valve. The gas is transported in the port, and the airtight effect of the valve can be detected by the sensor. After the current valve detection is completed, the motor 201 drives the driving disk 202 to rotate, and the detection and use of the next valve is realized, thereby improving the detection connection rate of the valve. When detecting valves of different sizes, there is a deviation between the center of the contact disk 502 and the port center of the valve. At this time, the screw rod 401 is rotated by rotating the knob 402. Since the sliding block 403 threadedly connected to the screw rod 401 slides and contacts the base 1, when the screw rod 401 is rotated, the position of the cylinder 404 on the base 1 is adjusted, so that the contact disk 502 slidably plugged into the mounting groove 405 through the plug-in block 501 can be adjusted to align at the port of the valve, meeting the use requirements.The contents not described in detail in this specification belong to the prior art known to professionals in this field.
