Intelligent electric control pressure electromagnetic valve

Abstract

The invention relates to the technical field of pressure electromagnetic valves, in particular to an intelligent electric control pressure electromagnetic valve. Comprising a valve body, an air valve rod and a pressure cover, a channel hole is formed in the valve body, the air valve rod penetrates through the channel hole, and a pressure relief hole is formed in the air valve rod; an electromagnetic assembly is arranged in the valve body, and a permanent magnet is arranged on the pressure cover; a pipe joint is arranged at the lower end of the valve body, the pipe joint is communicated with the pressure relief hole, and a pressure sensor is arranged on the pipe joint; the pressure sensor and the electromagnetic assembly are respectively connected with a main control board of the electric pressure cooker through leads; the pressure cooker is reasonable in structure, the sensing base is communicated with the pressure relief hole through the branch air channel on the pipe connector, the pressure sensor outputs a signal to the main control panel of the pressure cooker so that the current direction of the electromagnetic valve can be changed, and the electromagnetic assembly and the pressure cover are magnetically repelled and suspended to achieve intelligent pressure control and automatic pressure maintaining and relief. The pressure sensor monitors the internal pressure of the pressure cooker in real time, the main control board adjusts the current in the electromagnetic assembly in real time, and the accuracy of the set air pressure in the pressure cooker is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pressure solenoid valves, in particular to an intelligent electronically controlled pressure solenoid valve. Background technique [0002] Existing cooking utensils such as electric pressure cookers use the principle that the magnetic valve and the electromagnetic sucker can generate both suction and repulsion to realize stepless adjustment of the pressure limit value of the electric pressure cooker. Its implementation is that when the electromagnetic chuck is not energized, the pressure-limiting pressure of the electric pressure cooker is determined by the suction force generated by the electromagnetic chuck and the magnetic valve; when the electromagnetic chuck is energized with direct current that increases from small to large, the electromagnetic chuck will generate adjacent to the magnetic valve. If the magnetic pole with the same surface is used, the repulsive force of the same magnetic pole will re...

Problems solved by technology

[0003] The insulation between the iron core and the winding wire of the existing solenoid valve is generally realized by enameled wire and insulating tape. The solenoid valve on the electric pressure cooker is easily invaded by water vapor, resulting in a decrease in insulation performance and affecting the service life of the solenoid valve.

Existing pressure solenoid valves are all independent components that need to be assembled multiple times, especially the solenoid valve uses tape insulation layer filling and winding process, the rupture and damage of the tape insulation layer during the assembly process will lead to damage to the solenoid valve

The existing pressure solenoid valve cannot adjust the pressure limit of the solenoid valve according to the pressure inside the electric pressure cooker, so that there is a safety problem in the use of the electric pressure cooker
