Intelligent explosion-proof solenoid valve

Abstract

The invention provides an intelligent explosion-proof solenoid valve. The intelligent explosion-proof solenoid valve comprises a valve body and a valve cover, wherein the valve body is internally provided with an air inlet channel and an air outlet channel; a main valve element assembly is arranged in the valve cover; the upper end of the main valve element assembly is connected with a valve element lifting mechanism by a pull rod; the lower end of the pull rod is fixedly arranged at the upper end of the main valve element assembly; the upper end of the pull rod upwards stretches out of the top of the valve cover and is connected with the valve element lifting mechanism. The valve element lifting mechanism is arranged in a shield and the shield is fixedly arranged at the top of the valve cover; a motor which is vertically arranged in arranged above the shield; the output shaft of the motor is connected with the valve element lifting mechanism; the motor is located in a control cabinet; the control cabinet is fixed above the shield; a lithium battery and a control panel are further arranged in the control cabinet; a display screen is arranged on the side wall of the control cabinet; a solar panel for charging the lithium battery is arranged on the outer side of the control cabinet. The intelligent explosion-proof solenoid valve can be used for independently finishing the control of switching on and off the valve in the field, and other existing equipment on a wellhead is not needed; the control reliability is improved.

Description

technical field [0001] The invention relates to a valve used for the wellhead of a gas well, in particular to an intelligent explosion-proof electromagnetic valve. Background technique [0002] With the vigorous promotion and application of natural gas in my country, solenoid valves are widely used in gas wells as safety shut-off valves. However, the opening height of the spool of the traditional solenoid valve is limited, and throttling often occurs, which affects the production efficiency of the gas well. At present, the opening height of the main valve core of the solenoid valve is increased by means of evacuation, that is, the opening of the on-site shut-off valve is usually in the form of evacuation, and the gas in the upper chamber is directly discharged to the outside. Adopting this scheme will cause a lot of potential safety hazards while wasting gas sources, polluting the environment, and increasing the workload, especially for wells with high sulfur content. In a...

Adopting this scheme will cause a lot of safety hazards while wasting gas sources, polluting the environment, and increasing workload, especially for high-sulfur wells

In addition, under the low temperature conditions in winter, the phenomenon of freezing and blocking of traditional solenoid valves occurs frequently, and the shut-off valves produced by various manufacturers cannot completely solve the problems of freezing and blocking in winter; at present, the solenoid valves of various wellhead manufacturers have to rely on the wellhead remote transmission control system Without its own independent control mechanism, in case of continuous rainy weather or power feed caused by control system failure, remote operation will not be possible, and the effect of remote or automatic control of the shut-off valve will be lost.
