Abstract

The invention relates to the technical field of water attach pressure release valves, in particular to a blade motor directly driven multi-redundance electromagnetic piloted safe water attack pressure release valve. The valve comprises a handwheel, a blade motor, a valve cover, an electromagnetic piloted valve, a mechanical piloted valve and a main valve body. A special-shaped outer thread plug is rotatably connected with the valve cover, and the blade motor is used for driving the special-shaped outer thread plug to rotate; an oil path between the main valve body and the gear motor is provided with the electromagnetic piloted valve, the mechanical piloted valve, a first stop valve and a second stop valve. An oil inlet of the main body is provided with a pressure sensor, and the controller acquires a pressure value of the pressure sensor and controls the electromagnetic piloted valve to reverse according to the pressure value. The blade motor directly driven multi-redundance electromagnetic piloted safe water attack pressure release valve solves the problem that an existing water attach pressure relief valve cannot relieve pressure automatically during use.

Description

technical field [0001] The invention relates to the technical field of water hammer pressure relief valves, in particular to a multi-redundant electromagnetic pilot type safety water hammer pressure relief valve directly driven by vane motors. Background technique [0002] In long-distance oil pipelines, unexpected shutdown of pumps or abnormal opening and closing of valves will cause water hammer, which may cause local overpressure in the pipeline and cause pipe burst accidents. In order to ensure the safe operation of long-distance oil pipelines and related equipment, water hammer pressure relief valves are usually used to release water hammer pressure. [0003] When water hammer occurs in the pipeline, the pressure relief valve can quickly open and release the high-pressure medium, so that the pipeline pressure returns to the normal range, so as to achieve the purpose of protecting the pipeline and the equipment in the pipeline. Therefore, the opening speed of the pressu...
