Valve action alarm device and valve

Abstract

The invention provides a valve action alarm device and a valve. The valve comprises a handle and a valve body. The valve action alarm device is characterized by comprising a power supply, a trigger component, an inductive switch and an audible and visual alarm; the power supply is electrically connected with the audible and visual alarm; the inductive switch is connected between the power supply and the audible and visual alarm in series; the trigger component is in inductive connection with the inductive switch; the trigger component is arranged on the lower surface of the handle; the inductive switch is arranged on the portion, under the trigger component, of the upper surface of the valve body; and the audible and visual alarm is arranged on the surface of the valve body. When the handle is opened or closed, the trigger component on the lower surface of the handle triggers the inductive switch to work, so that the power supply, the inductive switch and the audible and visual alarm are connected in series to form a closed loop, and the audible and visual alarm on the surface of the valve body is driven to give sound alarms and flash alarms, so that operators are prompted to take corresponding control measures, and the using safety of the valve is improved.

Description

technical field [0001] The technical field of mechanical control of the present invention particularly relates to a valve action alarm device and a valve. Background technique [0002] As a common opening and closing device in pipelines, valves can be seen everywhere in modern industrial production, pipeline storage and transportation and other fields. [0003] In the process of oil and gas exploration, storage and transportation, and petrochemical production, the closing and opening of many valves is very critical. An improper valve closing or opening may cause extremely serious production accidents, and the consequences are immeasurable. In particular, if the operator opens and closes the valve in an emergency, it is easy to cause wrong operations or actions such as valve staggering, wrong closing, missed opening, and missed closing, and such errors cannot be found in time after the wrong operation or action occurs. Thereby, it is easy to cause accidents such as running o...

[0003] In the process of oil and gas exploration, storage and transportation, and petrochemical production, the closing and opening of many valves is very critical. An improper valve closing or opening may cause extremely serious production accidents, and the consequences are immeasurable

In particular, if the operator opens and closes the valve in an emergency, it is easy to cause wrong operations or actions such as valve staggering, wrong closing, missed opening, and missed closing, and such errors cannot be found in time after the wrong operation or action occurs. As a result, it is easy to cause accidents such as material running, mixing and pressure holding, and may even cause fires and cause major accidents such as factory shutdowns.
