Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing detection, in particular to a fire valve switch detection device. Background Art

[0002] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves are often used to control the on and off of high-pressure liquid or gas circuits during use, and need to withstand greater pressure during the opening and closing process. Therefore, valves need to undergo multiple quality tests before leaving the factory.

[0003] However, the opening and closing of existing valves must be manually operated by operators. It is very time-consuming and laborious to obtain thousands or even tens of thousands of valve opening and closing test data, and the test data is not very accurate. At this time, a device is needed to help operators automatically operate the valve and obtain test data. Utility Model Content

A first fixing device for fixing the fixed plate is also provided on the valve body, the first fixing device includes a first fixing rod and a second fixing rod matched with the valve body, the first fixing rod and the second fixing rod are arranged on the valve body through the second fixing device, four first screws are evenly arranged between the first fixing rod, the second fixing rod and the fixed plate, eight upper nuts are locked on the first screw at the fixed plate position, eight lower nuts are locked at the first screw at the first fixing rod and the second fixing plate position, the second fixing device includes two second screws, the second screw is arranged on the first fixing rod and the second fixing rod, the second screw is located at the first fixing rod position and is locked with two front nuts, and the second screw is located at the second fixing rod position and is locked with two rear nuts.

[0006] A further improvement is that: the fixing plate is provided with an adjusting slot for adjusting the distance between the first fixing rod and the second fixing rod.

[0007] A further improvement is that: a fixing groove is provided on the second fixing rod, an elastic layer is provided in the fixing groove, and the elastic layer is a rubber layer.

[0008] A further improvement is that: a square channel is opened on the rotating shaft of the servo motor, the opening and closing rod is inserted into the square channel, and a fastening bolt is locked between the rotating shaft and the opening and closing rod.

[0009] By adopting the above technical solution, the beneficial effects of the utility model are:

[0010] The structure is simple and the detection is convenient. When in use, the controller controls the servo motor to rotate, and the servo motor drives the opening and closing rod to open and close the valve stem, and then transmits a cycle to the technical device, and repeats this process to detect the valve switch and obtain accurate data. It is not only convenient to operate, but also saves labor and is conducive to detection and use in production. BRIEF DESCRIPTION OF THE DRAWINGS
