Abstract

The invention relates to a natural gas electromagnetic valve, which comprises a valve body, wherein the valve body comprises an inlet section and an outlet section; the inlet section and the outlet section are partitioned through a partition board; the periphery of the valve body is provided with at least two valve passages; the valve body corresponding to the valve passages is provided with valve core assemblies for partitioning or conducting the corresponding valve passages; and the valve core assembly comprises an armature, a guide sleeve covered outside the armature, a coil around the guide sleeve and a return spring arranged between the guide sleeve and the armature. The inlet section and the outlet section of the natural gas electromagnetic valve are partitioned through the partition board, the periphery of the valve is provided with the at least two valve passages, and each valve passage is provided with the corresponding valve core assembly to control the opening and closing of the corresponding valve passage so as to gradually open the valve passages, gradually accumulate the flow in a conveying pipeline, avoid flow surge caused by fully communicating the inlet section and the outlet section of the valve body at one time and prevent the flow surge of the conveying pipeline from sharply impacting monitoring equipment.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a natural gas solenoid valve. Background technique [0002] In pipeline transportation, valves need to be connected in series on the pipeline. In recent years, with the rapid development of solenoid valves, and the advantages of fast, convenient, and remote control, the application of solenoid valves in pipelines has gradually increased; however, in some In pipeline transportation with large diameter, such as natural gas transportation, due to the relatively large flow in the pipeline, most of the existing solenoid valves are single-armature. During use, one-time conduction or When the delivery pipeline is disconnected, due to the large diameter of the pipeline, when the armature opens all the pipelines at once, the flow rate increases suddenly, which will cause a huge impact on the flow monitoring equipment, and even damage the monitoring equipment in severe cases.
