Description

Technical Field

[0001] This utility model relates to the field of cryogenic shut-off valve technology, specifically to a detection device for a cryogenic shut-off valve with automatic feeding capability. Background Technology

[0002] In recent years, with the rapid development of the country, natural gas, a new energy source, has been widely used due to its environmental friendliness, cleanliness, and affordability. The amount of supporting equipment for natural gas storage and transportation has also increased, with cryogenic valves being particularly prevalent. However, because cryogenic shut-off valves have a welded pipe at one end and a threaded end at the other, conventional testing methods are inefficient. A search revealed a valve testing device (publication number CN205038018U). This device includes a fixed base plate, a first side plate, a second side plate, and a guide rod mounted on the base plate. A screw connecting seat with a hollow channel is mounted on the first side plate, a screw seat with a hollow channel is mounted on the guide rod, and an adjustment mechanism on the second side plate for adjusting the testing space between the screw connecting seat and the screw seat. One end of the screw connecting seat is connected to a connecting hose serving as the testing source, and the other end is threaded to the connecting pipe end of the valve to be tested. One end of the screw seat is the inlet end, used for threaded connection to the internal thread end of the valve to be tested. The other end of the screw seat is connected to one end of the adjustment mechanism, and the outlet end of the screw seat is located on the side wall of the screw seat for installing a plug. This invention solves the problem of inconvenient sealing of valves during testing due to external pipes and connection to test pipelines.

[0003] In summary: In the above cases, rotating the adjusting screw facilitates the adjustment and installation of the shut-off valve, but this makes adjustment cumbersome. Similarly, the manual feeding method used in the above solutions also presents feeding difficulties. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a detection device for a cryogenic shut-off valve that can automatically feed materials. This solves the problem in the above-mentioned cases proposed in the background art, where adjusting and installing the shut-off valve is facilitated by rotating the adjusting screw, which results in cumbersome adjustment. At the same time, the above solutions also use manual feeding, which is also cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detection device for a low-temperature shut-off valve that can automatically feed materials, including a drive adjustment structure, wherein an adjustment feeding structure is installed above the drive adjustment structure.

[0006] The drive adjustment structure includes a fixed platform as a base, and a connecting seat with a groove is fixedly installed on the fixed platform. At the same time, the first electric slide rail assembly is fixedly installed on the connecting seat through the groove.

[0007] A screw connector with a connecting hose is fixedly installed on one side above the connector, and a screw seat with a plug on its surface is fixedly installed on the other side above the connector via a slide rail and a slider. At the same time, a first electric telescopic rod with its output end penetrating through a through-hole plate is fixedly installed on one side of the screw seat. The first electric telescopic rod is fixedly installed on the other side above the connector via the through-hole plate.

[0011] Preferably, the adjusting feeding structure includes a through-slot connecting frame fixedly installed with the first electric slide rail group, and a second electric slide rail group fixedly installed above the through-slot connecting frame. At the same time, a second electric telescopic rod is fixedly installed between the second electric slide rail groups, and the output end of the second electric telescopic rod extends into the lower part of the through-slot connecting frame.

[0012] By adopting the above technical solution, the second electric telescopic rod is installed to control the lifting and adjustment.

[0013] Preferably, the output end of the second electric telescopic rod is fixedly mounted with a recessed platform via a connecting plate, and a through-hole platform with a sliding groove is fixedly mounted inside the recessed platform. At the same time, a rotary motor that passes through the through-hole platform is fixedly mounted inside the recessed platform.

[0020] (1) This case solves the problem of the troublesome adjustment of the shut-off valve when the screw is rotated to facilitate the adjustment and installation of the shut-off valve. When the shut-off valve needs to be placed for testing, the relative sliding distance between the screw seat and the screw connecting seat is changed when the first electric telescopic rod is controlled to change the operation of the shut-off valve, thus facilitating the matching installation and testing of the shut-off valve.

[0021] (2) By setting the feeding structure, the problem of manual feeding in the above scheme is solved. When the gate valve needs to be fed for inspection, the first electric slide rail group is controlled to move the through slot connecting frame to the material placement frame. At this time, the vision inspection instrument controls the second electric slide rail group and the second electric telescopic rod to move the control clamp downward to clamp and fix the gate valve inside the material placement frame. Then, the second electric slide rail group and the second electric telescopic rod are controlled to run in the opposite direction to move the gate valve to the position between the screw seat and the screw connecting seat. At this time, the rotary motor is controlled to facilitate the docking of both ends of the gate valve with the screw seat and the screw connecting seat. The gate valve is then inspected, and the inspected gate valve is clamped and placed inside the qualified frame by the control clamp again. Attached Figure Description

Except for the fixed platform 101, the connecting seat 102, and the first electric telescopic rod 1010, all other components are installed according to the component installation settings in the prior art. The component installation settings in the prior art are used to effectively clamp and detect the shut-off valve.

[0029] Furthermore, on the other side above the connecting seat 102, a qualified frame 1011 and a material placement frame 1012 are fixedly installed, and a controller 1013 is fixedly installed on the other side above the connecting seat 102.

[0030] like Figure 3 and Figure 4As shown, an adjustable feeding structure 2 is installed above the drive adjustment structure 1. The adjustable feeding structure 2 includes a slotted connecting frame 201 fixedly installed with the first electric slide rail assembly 103, and a second electric slide rail assembly 202 is fixedly installed above the slotted connecting frame 201. A second electric telescopic rod 203 is fixedly installed between the second electric slide rail assemblies 202. The output end of the second electric telescopic rod 203 extends below the inside of the slotted connecting frame 201.

[0032] In the above scheme, when the shut-off valve needs to be inspected for material feeding, the first electric slide rail assembly 103 is controlled to move the through slot connecting frame 201 to the material placement frame position 1012. At this time, the vision inspection instrument 2011 controls the second electric slide rail assembly 202 and the second electric telescopic rod 203 to move the control clamp 2012 downward, thereby clamping and fixing the shut-off valve inside the material placement frame 1012. Then, the second electric slide rail assembly 202 and the second electric telescopic rod 203 are controlled to run in reverse, moving the shut-off valve to the position between the screw seat 108 and the screw connecting seat 104. Afterwards, when the first electric telescopic rod 1010 is operated, the relative sliding distance between the screw seat 108 and the screw connecting seat 104 is changed to facilitate the matching installation and testing of the shut-off valve. When the visual inspection instrument 2011 detects a deviation in the alignment angle between the shut-off valve and the screw seat 108 and the screw connecting seat 104 during the descent of the shut-off valve, the rotary motor 207 is controlled to operate to ensure that both ends of the shut-off valve are matched and connected with the screw seat 108 and the screw connecting seat 104, and then the shut-off valve is tested. After the test, the shut-off valve is clamped again by the control clamp 2012 and placed inside the qualified frame 1011.
