Abstract

The flow control valve with the anti-loosening function comprises a valve body, a lead screw rotationally installed on the valve body, a six-edge sleeve connected to the lead screw in a threaded mode, a hand wheel connected to the six-edge sleeve in a sleeving mode and a locking nut, and the hand wheel can drive the lead screw to rotate relative to the valve body through the six-edge sleeve and is locked and limited through the locking nut; the flow control valve further comprises an anti-loosening piece and an opening nut, and the anti-loosening piece can act on the hand wheel and the locking nut at the same time so that the hand wheel and the locking nut can be relatively fixed. The opening nut is connected to the lead screw in a threaded mode and matched with the anti-loosening piece so as to limit the anti-loosening piece to be separated from the hand wheel and the locking nut. According to the flow control valve, the anti-loosening function of the hand wheel in the flow control valve can be achieved, and the flow control valve is not affected by vibration of equipment.

Description

technical field [0001] The invention belongs to the technical field related to flow control valves, in particular to a flow control valve with an anti-loosening function. Background technique [0002] At present, the flow control valve used on the equipment in the enterprise is affected by the vibration when the equipment is working, so that the hand wheel of the flow control valve installed on the equipment will be disengaged from the lead screw of the flow control valve and fall, thus affecting Enterprises for manual control of flow control valves. Contents of the invention [0003] Based on this, it is necessary to provide a flow control valve with an anti-loosening function in view of the technical problems existing in the prior art. [0004] A flow control valve with anti-loosening function, comprising a valve body, a lead screw rotatably mounted on the valve body, a hexagonal sleeve screwed to the lead screw, and a hexagonal sleeve sleeved on the hexagonal sleeve A...
