Valve with valve opening degree position indication function

Abstract

The invention discloses a valve with a valve opening degree position indication function. Opening and closing or opening degree operation of the valve is controlled according to experience of people, and unnecessary loss is often caused. A data acquisition or electric control system is complex in structure, high in price, complex in adjustment and inconvenient to popularize. The valve comprises a valve body (5), a follow-up device is fixed to the top of a transmission mechanism of the valve body, a turning scale device used for indicating the opening degree of the valve is connected to the follow-up device in an inserted mode, and an opening degree pointer (1) used for indicating the opening degree of the valve is fixed to a shell of the valve body; the turning scale device comprises a dial (2) and a turning head, and the turning head is fixed on the dial and used for changing the position of the dial. The valve with the valve opening degree position indication function is used for indicating the opening position of the valve.

Description

Technical field [0001] The present invention relates to the valve field, and more particularly to a valve having a valve opening position indicated. Background technique [0002] In the production site or experimental places such as energy chemical, electricity, manufacturing, food, food pharmaceutical, municipal engineering and mining industries, often use a variety of valves due to traffic or pressure regulation and maintenance, equipment replacement. Automatic control valves with high degree of automation control, as well as traditional artificial control valves. In these valves, depending on the operating conditions, it may be normally open, regular, or adjusted to a certain opening to accommodate different needs. The control of many valves well known is controlled by manual control, but the valve has no level indication or indication location is not convenient for observation, which allows the valve switch or opening degree operation to control the human experience, often br...

AI Technical Summary

Problems solved by technology

Many well-known valves are still controlled manually, but the valve has no opening indication or the indicated position is not easy to observe, which makes the valve switch or opening operation rely on human experience to control, which often brings unnecessary troubles. loss

However, the use of digital acquisition or electric control system has complex structure, expensive price, complicated adjustment and inconvenient popularization.
