Electric pipeline rapid safety valve with automatic power-failure reset function

Abstract

The invention provides an electric pipeline rapid safety valve with an automatic power-failure reset function. The safety valve is characterized in that a valve rod is sequentially provided with a suspension arm and an electromagnetic clutch reset device, wherein a counterweight is hung on the suspension arm, and a main control box is arranged on the upper part of a drive device; the opening / closing of the valve is controlled through a signal transmitted by a control system of the main control box, the valve generally stays at an open state, when the pressure of a pipeline is extremely low or gas is leaked from the pipeline, a pressure alarming sensor on the pipeline transmits a signal to the control system of the main control box, the control system compares the received signal with a set value to transmit a control signal, so that the drive device is actuated, and the valve can be rapidly opened / closed. The electric pipeline rapid safety valve has the beneficial effects that the pipeline can be accurately and timely cut off or opened when in emergency, the rapid safety valve of the pipeline can be closed / opened when in power failure, and the secondary disaster can be avoided. The rapid safety valve is reasonable in structure, sensitive and reliable to operate, convenient to maintain, and high in action speed, and is a necessary safety device in the gas stove control of the industries such as metallurgy, petrochemical, power stations and building materials.

Description

technical field [0001] The invention relates to an electric fast safety valve for pipelines, in particular to an electric fast safety valve for pipelines with the function of automatic reset after power failure. Background technique [0002] Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. As a common and commonly used tool, the market application of safety valves The range is extremely wide, and its action reliability and performance are directly related to the safety of equipment and people. [0003] With the enhancement of people's environmental awareness and sense of social responsibility, and the improvement of national environmental protection policies, natural gas and coal-based gas have replaced coal, which can cause heavy pollution, in power generation, metallurgy and other industries ...
