Abstract

The invention discloses an oval hand wheel ball valve with a self-locking limiting device. The oval hand wheel ball valve comprises a valve body, a valve seat is arranged in the middle of the valve body, a valve ball is arranged in the valve seat, an end face flange is arranged outside the valve ball and the valve seat, an oval hand wheel is arranged above the end face flange and comprises a longshaft and a short shaft, and the oval hand wheel is pressed on the end face flange through a pressing nut and a valve rod. The self-locking limiting device for locking the oval hand wheel is arrangedon the end face flange and comprises a supporting rod connected to the end face flange in an abutting mode, and U-shaped flat steel is arranged at the top end of the supporting rod and wraps the outerside of the oval hand wheel. 1, the operation radius is small, and the installation space is saved; 2, the opening and closing states of the valve are convenient to identify; and 3, the hand wheel isprovided with the self-locking limiting device capable of sliding up and down, so that the required state position of the valve can be locked.

Description

technical field [0001] The invention relates to the field of ship pipeline equipment, in particular to an elliptical handwheel ball valve with a self-locking limit device. Background technique [0002] With the in-depth development of the shipbuilding industry, modern ship design is becoming more and more refined. In order to ensure the smooth opening and closing of the traditionally used handle ball valve, the handle is generally designed to be longer. When operating the valve, the handle occupies a relatively large radius of rotation, and it is easy to interfere with the surrounding pipe accessories. At the same time, in accordance with the general layout guidelines of the pipeline, it is generally recommended to use the handwheel operation type for valves below the flower plate for easy operation. Contents of the invention [0003] In order to solve the above problems, the invention discloses an elliptical handwheel ball valve with a self-locking limiting device. [...
