Novel sight glass of ball valve

Abstract

The invention discloses a new type of sight glass for a ball valve. The sight glass is installed on the top of the water inlet pipe of the valve body, and a running wheel is installed in the sight glass; the running wheel is installed on a bracket inside the sight glass, and the running wheel includes a hub and blades. The blades are evenly arranged around the hub, and the indicator lights are installed on the side of the blades facing the mirror glass. There are symmetrical blind holes a and b blind holes on both sides of the hub axis of the runner. Sliding bearings are installed in the blind holes a and blind holes b. A battery is installed in the hole, and the battery is connected to the indicator light on the blade. The technical purpose of the present invention is to provide a new type of sight glass that can observe the flow in the pipe more clearly and can be applied to the ball valve on the turbid medium.

Description

technical field [0001] The invention relates to the field of valves, in particular to a novel sight glass for ball valves. Background technique [0002] Ball valve is a widely used fluid control component, which has the functions of diversion, interception, adjustment and diversion. Common ball valves on the market close the valve by rotating the valve core to make the valve core contact with the valve seat, especially suitable for media containing fibers and tiny solid particles. In my country, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, electric power, municipal, steel and other industries, and occupy a pivotal position in the national economy. It has the action of rotating 90 degrees. The cock body is a sphere with a circular through hole or channel passing through its axis. [0003] The ball valve has the advantages of small fluid resistance, simple structure, small volu...

Problems solved by technology

[0003] The ball valve has the advantages of small fluid resistance, simple structure, small volume, light weight, compactness and reliability, etc. However, when the ball valve transports medium with large impurities, the ball valve is easy to be completely blocked or partially blocked, which reduces the transmission capacity of the pipeline system. Most of the existing ball valves do not have the dredging function, or the dredging effect is not good; and the existing ball valves and sight glasses are installed separately in the pipeline system, so that there are many installation procedures when installing the sight glasses and ball valves. And increase the number of parts, improve the cost of use, reduce the reliability
