Definitions

  • the invention relates to a pipeline control valve, which belongs to the technical field of gas and liquid switching, and is particularly suitable for being an on-off control valve for flammable, explosive, or toxic gases. Background technique
  • the existing pipeline control valve is one that manually rotates a threaded valve stem or directly lifts the valve stem to open and close the valve, thereby achieving the purpose of opening or closing the pipeline and flowing gas or liquid.
  • Disadvantages of this type of manual valve are: the opening speed ⁇ 1 is time-consuming and labor-intensive, and cannot realize the needs of automatic control.
  • Another type of on-off valve is a spring-controlled safety valve, or a gravity-controlled safety valve. It is based on spring force or gravity. When the pressure in the pipeline is less than or greater than a certain state, the flow material in the pipeline is cut off or conducted. (Gas or liquid).
  • a type of safety valve has the disadvantage that its leakage prevention function is that when the pipeline is ruptured, or falls off, or the gas pressure is not greatly reduced, the environment (such as the hospital) has made people feel a gas leak, and the protector cannot. Automatic shutdown, because there are no electrical control components, so it can not be matched with electrical control devices.
  • Another type of pipeline control valve is a common solenoid control valve as a hydraulic control device.
  • valve stem By electromagnetic force, and the valve stem itself is a valve, which closes the valve hole channel with its outer circle.
  • the disadvantage is that the valve core and the valve hole are dynamically matched and have gaps, which cannot seal off the flowing material in the pipeline, especially the gas in the pipeline.
  • the contact surface between the valve stem and the hole is large, it is easy for dirt to stay in the space, which can cause the valve stem to become blocked or sticky.
  • the electromagnetic force is not large, the operation fails.
  • the purpose of the present invention is to overcome the shortcomings of the prior art and provide a new pipeline control valve. Its main technical features include: 1. Fast switching speed and high working sensitivity;
