Fuel gas isolated type embedded electromagnetic valve

Abstract

The invention relates to the field of fuel gas electromagnetic valves, in particular to a fuel gas isolated type embedded electromagnetic valve which comprises a valve body. Blocking iron is arranged on the upper portion of the left side of the valve body, and a movable rod is arranged below the blocking iron. The movable rod is connected with the valve body through a spring, and the lower side of the movable rod is tightly contacted with a sealing valve opening of the valve body. The sealing valve opening of the valve body is communicated with an air inlet channel in the valve body, and the movable rod is contacted with a guiding pipe. An electromagnetic coil is arranged on the periphery of the guiding pipe, and an embedded electromagnetic valve outer shell is arranged on the outer side of the electromagnetic coil. When the electromagnetic coil is electrified, the blocking iron attracts the movable rod so as to enable a sealing gasket to be away from the sealing valve opening of the valve body. The fuel gas isolated type embedded electromagnetic valve has the advantages that due to the fact that the all-metal whole structural design is utilized by an outer shell of the embedded electromagnetic valve, the whole outer shell is a complete magnetic conductance loop, so that the whole electromagnetic field is shielded, therefore, electromagnetic force generated by the electromagnetic field can be fully utilized, and loss of electric energy and magnetic force is reduced.

Description

technical field [0001] The invention relates to the field of gas solenoid valves, in particular to a gas isolation type embedded solenoid valve. Background technique [0002] The current gas solenoid valves generally use a sealing structure to place the solenoid coil outside the valve body, or use an integral sealing mechanism to seal the solenoid coil together in the gas chamber. These two designs have the following problems respectively: the solenoid coil is set on the valve body. In vitro, the volume is very large and takes up a lot of space. The corresponding moving rod needs to be lengthened, and there are more consumables. The magnetic circuit of the electromagnetic mechanism is not closed enough, resulting in increased magnetic flux leakage. Under the same suction requirements, it needs to consume more power; electromagnetic coils Sealed in the gas cavity, the copper enameled wire, an important material for the electromagnetic coil, is likely to chemically react with...
