Abstract

The invention relates to the field of valves, and discloses a device capable of locking a valve opening and closing position. The device comprises a hand wheel, wherein the middle of the hand wheel isconnected with a shell, the top of the shell is installed with a card switch, a driving motor is arranged in the shell, a sleeve is welded to the bottom of the shell, the bottom end of the sleeve isconnected with a valve body in a rotating mode, the bottom end of a transmission shaft of the driving motor penetrates the shell and extends to the upper portion of the inner side of the sleeve, and the lower portion of the transmission shaft is provided with an external threaded portion. By adopting the split design of a valve rod and a transmission rod, the transmission rod is arranged in the sleeve, the sleeve is connected with the hand wheel through the shell, the driving motor is arranged in the shell to control the power transmission of the transmission rod and the valve rod, the transmission rod is separated from the valve rod in the normal state, at the moment, the rotating hand wheel cannot drive the valve rod to rotate, the opening and closing position of the valve cannot be adjusted, and man-made malignant, intentional or error operations are actively prevented.

Description

technical field [0001] The invention relates to the field of valves, in particular to a device for locking the opening and closing positions of valves. Background technique [0002] Indoors are usually installed with a main water valve indoors at the beginning of decoration, which cooperates with the outdoor main water valve to form a double protection. However, due to the dark environment and unclear markings, the outdoor water valve often turns off by mistake. As a result, the users who were mistakenly closed mistakenly thought that the water was cut off, there was a problem with the pipeline, etc., which brought inconvenience to the use of the residents. [0003] The technical solution provided by the patent document CN206347186U all adopts passive protection after the valve body fails, and cannot actively prevent human operation, so the protection capability is limited. [0004] Therefore, it is necessary to design a device for locking the opening and closing position o...
