Problems solved by technology

[0002] At present, the known dark stem gate valves used in industrial pipelines are difficult to judge the opening and closing of the valve from the appearance during work, which is prone to misoperation or twisting of the valve; moreover, industrial pipelines often need to adjust the opening of the valve to meet the system work. It is very difficult to adjust because there is no way to judge the opening of the valve, and when the valve is twisted, maintenance must stop production and cause losses

Embodiment Construction

[0012] exist figure 1 In the shown embodiment, the toggle wheel (10) is fixed on the valve stem (9), the support plate (3) is fixed on the platform of the packing gland (2) through the packing gland nut (1), and the toothed plate (4 ) is installed on the short shaft 1 (301) of the support plate (3), and the gear cover (5) is installed on the support plate (3) and is buckled by the pressure hook (501).

[0013] From figure 2 It can be seen that the annular grooves (401) on the tooth plate (4) and the convex points (302) on the support plate (3) (4 are evenly distributed on the outer wall of the short axis 1) are mate with each other. Every time the valve stem (9) rotates one circle, the tooth plate (4) just turns over a plate tooth (403) that is, turns over a main scale mark (402), and the protrusion on the outer wall of the short axis 1 (301) on the support plate (3) The point (302) is mate with the next concave groove (401) on the inner wall of the shaft hole on the toothe...

Abstract

The opening display device for hidden rod gate valve has one shifting wheel on the valve rod, one support board with at least one raised spot or notched pit fixed onto the stuffing gland, and one toothed disc with teeth and scales installed on the support board. The teeth, the scales and the notched pit or raised spot on the toothed disc in the same number are distributed in ring; and the notched pit or raised spot on the toothed disc and the raised spot or notched pit on the support board are meshed each other. When the valve rod rotates by one certain angle, the notched pit or raised spot on the toothed disc and the raised spot or notched pit on the support board are once meshed, and the toothed disc rotates by one scale.

Description

Technical field [0001] The invention relates to a device capable of displaying the opening and closing and opening degree of a hidden rod gate valve in an industrial pipeline. Background technique [0002] At present, the known dark stem gate valves used in industrial pipelines are difficult to judge the opening and closing of the valve from the appearance during work, which is prone to misoperation or twisting of the valve; moreover, industrial pipelines often need to adjust the opening of the valve to meet the system work. It is very difficult to adjust because there is no way to judge the opening of the valve, and when the valve is twisted, maintenance must stop production and cause losses. Contents of the invention [0003] In order to overcome the disadvantage that it is difficult to judge the opening and closing and opening degree of the valve from the appearance of the existing dark rod gate valve, the invention provides an opening display device, which can display ...
