Description

Technical Field

[0001] The utility model belongs to the technical field of valve detection, and relates to a torque detection device, in particular to a valve torque detection device. Background Art

[0002] Industrial valves, such as stop valves, ball valves, gate valves, butterfly valves, etc., are mechanical products that withstand internal pressure and must be opened and closed under rated pressure and flow. The opening and closing force and opening and closing torque are the force and torque that must be applied to open or close the valve. The valve rotating device automatically controls the opening or closing of the valve to be tested. During the opening or closing process of the valve rotating device, the torque sensor dynamically detects the force value of the valve rotating device, thereby automatically obtaining the torque of the valve to be tested. In the current valve torque detection, manual tensioners are usually used for detection, which has low work efficiency and inconvenient operation.

[0003] After searching, a valve head torque detection device is disclosed in Chinese patent documents [Application No.: CN202122959700.1; Publication No.: CN216791631U]. This device is arranged by a rotating disk, a torque connecting shaft, and a torque sensor. The rotating disk drives the valve head to rotate, and then the torque during the rotation of the valve head is transmitted to the torque sensor through the torque connecting shaft, so as to directly measure the torque of the valve head.

[0004] The rotating disk and torque shaft disclosed in the patent can transmit the torque during the rotation process to the torque sensor. However, the device detects the torque by driving the rotating disk with power, and the setting of multiple transmission structures affects the output and detection of torque, which is easy to interfere with the accuracy of the valve during the torque detection process. The accuracy is poor and it cannot rotate stably with the valve operating disk. Utility Model Content

[0013] With the above structure, two groups of symmetrically arranged rubber columns can stably fit the outer wall of the valve operating panel, ensuring the accuracy of torque detection.

[0014] The bottom end of the bidirectional screw rod is fixedly connected with an inner hexagonal end, and the inner hexagonal end is arranged at the bottom end of the rotating drum.

[0015] The above structure makes it easy for users to rotate and adjust the bidirectional screw through the hexagonal end at the bottom, ensuring the adjustment effect of the two sets of rubber columns, facilitating installation with valve operating panels of different sizes, and facilitating stable torque detection.

[0016] The top plate is fixedly connected with fixing rods at the four corners, and the bottom ends of the fixing rods are fixedly connected with mounting plates. A supporting ring is arranged below the mounting plate, and the supporting ring is installed at the bottom end of the mounting plate by bolts.

[0017] With the above structure, by setting the fixing rod, it is convenient to install and fix the top plate above the valve, thereby achieving the stability of the device operation.

[0018] The support ring is The support ring is provided with a rubber pad fixedly connected to the upper surface of the support ring.

[0020] The outside of the torque sensor is electrically connected to a display screen, and the display screen is fixedly embedded and installed on the surface of the top plate.

[0021] The above structure makes it easy for the torque sensor to electrically transmit the torque of the valve rotation to the display screen for display, thereby realizing intuitive torque detection.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] 1. By rotating a rotating drum on the outer wall of the torque sensor, and under the action of the rubber column arranged on the outer wall of the rotating drum, the valve operating panel directly mobilizes the rubber column to rotate, thereby ensuring the accuracy of valve torque detection and avoiding torque errors in multi-stage transmission. In addition, the structure is compact and convenient for installation and connection of the valve.

[0024] 2.
