Abstract

The invention discloses a pilot valve, which comprises a valve main body, coils, a control box, a magnet, a pushing rod, a moving rod and a movable plug, wherein the valve main body is internally provided with a placing cavity, coil placing cavities are arranged around the placing cavity, the coils are installed in the coil placing cavities, the coils are electrically connected with the control box through a conductive wire, the right side in the placing cavity is provided with a fixing base, the fixing base is fixed in the placing cavity by a connecting block, the pushing rod is installed onthe fixing base, the left end of the pushing rod is provided with the magnet, the right end of the pushing rod is provided with the pushing block, a communicating cavity is arranged at the right sideof the placing cavity, the moving rod is installed in the communicating cavity, and a movable block is installed at the left end of the moving rod. Through arranging the valve main body, the coils, the control box, the magnet, the pushing rod, the moving rod and the movable plug, the problems of complex structure, inconvenient use, and inconvenient adjustment of flows between pipelines during theusing process are solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to pilot valves. Background technique [0002] The pilot valve is used to control the supply to the restricted flow control of the pilot valve, also known as the main valve. For example, pilot operated valves may be placed in risers and branches of heating and cooling systems used in various domestic and industrial applications. Pilot valves are generally smaller valves compared to pilot operated valves and are advantageous to use because a small and easily accessible supply from the pilot valve can be used to control higher pressures or higher flow supply, which would otherwise require much greater force to operate. The pilot valve is conventionally positioned outside the body of the pilot valve and connected to the body by one or more fluid conduits having outlets into the main flow region of the pilot valve chamber. [0003] However, the existing pilot valve has the following d...
