Problems solved by technology

In the CN200410002349.5 patent, custom production must be used, and it cannot be used in common with ordinary dark rod gate valves of the same specification
Adopting the transmission form of the gear mechanism, there are many parts connected on the basis of the original valve, and the processing is more troublesome and complicated.
And it can only be displayed in degrees of rotation, which is not intuitive enough

Abstract

The invention provides a stroke indication device of a non-rising stem gate valve, and relates to the field of water supply and drainage valves. The stroke indication device of the non-rising stem gate valve comprises an original valve body which is provided with a valve sleeve, a sliding hole is formed in the side face of the valve sleeve, a scale plate is arranged beside the sliding hole, an inner threaded sleeve is arranged on a valve rod in the valve sleeve, a sliding groove is arranged outside the inner threaded sleeve, and an indicator is arranged in the sliding groove and points to the sliding hole. On the basis that the structure and components of an original valve is not changed, a part of stroke is added on the valve rod of an original valve according to the picture, the part of stroke can be mounted on the original valve through the indicator, a scale tube and two fastening screws, the simple mechanism can be used for meeting requirements on stroke indication, the transformation is fast, volume production can be realized, energy consumption is lowered, raw materials and processes are eliminated to the largest extent, machining is simple, operation is simple and convenient, and labor intensity is lowered.

Description

technical field [0001] The invention relates to the field of water supply and drainage valves, in particular to a stroke indicating device for a dark rod gate valve. Background technique [0002] Commonly used dark stem gate valves do not have an indicating device. In practical applications, some working conditions and occasions require that an indicator device must be provided on the concealed stem gate valve, so that it is possible to intuitively know the opening stroke of the valve when it is in use. At this time, it is necessary to have an indicating device with a stroke. Custom production must be used, and it cannot be used in common with ordinary dark stem gate valves of the same specification, that is, non-standard production. [0003] The CN200410002349.5 invention discloses a display device for the opening of a dark rod gate valve, which is to install a dial wheel on the valve stem of the dark rod gate valve, and fix a support plate on the packing gland of the val...
