Pilot-type micro-resistance low-power-consumption large-diameter electromagnetic valve

Abstract

The invention relates to a pivot-type micro-resistance low-power-consumption large-diameter electromagnetic valve, which comprises a valve body, a pressure reduction passage on the left side in the valve body, a pressure increase passage on the right side in the valve body, two sealing plugs which are arranged at the upper port of a pressure reduction and increase passage and are respectively installed on pressure reduction and increase swing rods which are attracted and pulled by an electromagnetic attraction block, and pull-up trapezoidal squeezing blocks which are lifted up by the electromagnetic attraction block to squeeze locking blocks to be clamped in bayonets of a locking shaft to realize open and locked states of a sealing spool plate. The pivot-type micro-resistance low-power-consumption large-diameter electromagnetic valve is characterized in that a pulling spring is used to pull the pull-up trapezoidal squeezing blocks to move upwards to enable locking blocks to move towards the locking shaft in the middle; and when the bayonets of the locking shaft move to horizontal positions of the locking blocks, the locking blocks are clamped in the bayonets of the locking shaft, the upper inclined surfaces of the locking blocks lift and squeeze the upper edge inclined surfaces of the bayonets of the locking shaft, and the locking shaft is enabled to have an upward lifting force of driving the sealing spool plate to keep the sealing spool plate in an open state.

Description

technical field [0001] The invention relates to a pilot-operated solenoid valve with small resistance, low power consumption and large diameter, which is suitable for all liquid and gas media, and belongs to the technical field of comprehensive energy saving and emission reduction and the technical field of solenoid valves. Background technique [0002] Solenoid valve is a fast electric control valve set up to open or close the pipeline fluid in many pipeline transportation processes, but the existing solenoid valve does not have a large diameter, probably because the solenoid valve with large diameter must keep it open , needs to consume a lot of power, and it is uneconomical in industrial applications, so most of them use electric valves, but there are many processes that require that the valves can be automatically closed after a sudden power failure to reduce losses or prevent chemical materials in the pipeline from appearing Problem, therefore, inventing a large-diamet...

[0002] Solenoid valve is a fast electric control valve set up to open or close the pipeline fluid in many pipeline transportation processes, but the existing solenoid valve does not have a large diameter, probably because the solenoid valve with large diameter must keep it open , needs to consume a lot of power, and it is uneconomical in industrial applications, so most of them use electric valves, but there are many processes that require that the valves can be automatically closed after a sudden power failure to reduce losses or prevent chemical materials in the pipeline from appearing Therefore, it is imperative to invent a large-diameter solenoid valve with less power consumption in today's energy-scarce environment
