Regulator for pressure in pipeline

The utility model relates to the technical field of new energy power generation, and discloses a regulator for pressure in a pipeline, which is characterized in that a piston is movably connected in a through hole, baffle blocks are movably connected on the inner walls of the two sides of the through hole, arc grooves are formed on the two sides of the piston, a permanent magnet is slidably connected in a sliding chute, and a sliding block is slidably connected in an air outlet groove; and an electromagnet is embedded in the sliding block. According to the regulator for the pressure in the pipeline, when the pressure in the steam pipeline is too large, a piston moves towards the outer side under the action of the pressure, a check block enters an arc groove, a push plate is pushed after the check block enters the arc groove, contacts on an arc rod are in contact, a front circuit is switched on, an electromagnet is powered on to generate magnetism, and the pressure in the steam pipeline is regulated.
