Safe type intelligent air flow control device

Abstract

The invention discloses a safe type intelligent air flow control device. The safe type intelligent air flow control device comprises a flow controller, a flowmeter, a flow control valve, a pipeline, and a pressure relief pipe, wherein an electric valve body is arranged in the pressure relief pipe; the flowmeter and the pressure relief pipe are connected with the pipeline; the flow controller is connected with the pipeline through the flow control valve; an air inlet and an air outlet are respectively formed in two ends of the flow control valve; the flowmeter communicates with one end of the air outlet through the pipeline; a pressure sensor is arranged in the pipeline between the flowmeter and the air outlet; the flow control valve comprises an executing mechanism, a valve body and a valve core, wherein a motor is arranged in the executing mechanism; the valve core is arranged in a cavity of the valve body; and the valve core comprises a transmission shaft, a first valve rod, a secondvalve rod and a valve seat. The safe type intelligent gas flow control device disclosed by the invention has the beneficial effects that the capacity of the flow in the pipeline can be automaticallycontrolled according to requirements, and besides, the flow rate of the pipeline is monitored in real time; and when the air flow is abnormal, self-protection can be realized through pressure relief.

Description

technical field [0001] The invention belongs to the technical field of flow control, in particular to a safe intelligent gas flow control device. Background technique [0002] High-pressure automatic flow measurement and control device is an important executive element in industrial automation process measurement and control. With the rapid development of automation in the industrial field, it is being more and more used in the field of industrial production. Existing automatic gas control pipelines adjust the pressure by setting a fixed value through the pressure regulator, and the gas flow rate is set by the threshold value of the valve so that it enters the container; since most actuators are fixed value or manual It is impossible to realize the automatic regulation of the flow rate, which leads to a huge increase in workload and labor costs when controlling large-scale gas pipelines. Moreover, when the gas flow rate is abnormal, the flow control device and the pipeline c...

Problems solved by technology

Existing gas automatic control pipelines adjust the pressure by setting a fixed value through the pressure regulator, and set the fixed value of the gas flow rate through the threshold of the valve to make it enter the container; since most actuators are fixed value or manual It is impossible to realize the automatic regulation of the flow rate, which leads to a huge increase in workload and labor costs when controlling large-scale gas pipelines. Moreover, when the gas flow rate is abnormal, it is impossible to realize the self-relieving pressure of the flow control device and the pipeline. If it is serious, it will cause a pipe burst accident. Once the pipe burst occurs, it will not only cause economic losses but also cause serious environmental and social problems.
