Description
Technical field
The utility model relates to gas electromagnetic valve component, is specifically related to a kind of gas electromagnetic valve double spool assembly.
background technique
Gas electromagnetic valve is applicable to the fuel gas pipelines such as town gas, liquefied petroleum gas (LPG), rock gas and does the actuator that control is automatically carried out in two formula break-makes switchings.It is widely used in textile industry, the combustion gas heat setting of dyeing industry and glass, the kiln heating of bulb industry and the gas heating robot control system(RCS) of other industry.Gas electromagnetic valve can be divided into normally closed solenoid valve and normally open solenoid valve, normally closed solenoid valve according to the difference of on off state residing during power-off, during the normal position of power-off, is sealed by valve port, cut off the runner of controlled medium by armature deadweight, Packing spring and pressure medium.Electromagnetic coil energising after, solenoid valve overcome armature deadweight and Packing spring, pressure medium active force dynamic iron core is sucted together with sealing valve port pad, open valve port, controlled medium is negotiable.All rights reserved to control Engineering Network during normally open solenoid valve power-off, and electromagnetic attraction equals zero, and under the action of the spring dynamic iron core, valve rod is upwards mentioned, and all rights reserved for valve open CONTROL ENGINEERING China, and medium circulates.Move down because suction moves iron core when energized, promote valve rod, valve closing, medium is only disconnected.Gas electromagnetic valve system direct-acting type low-voltage solenoid valve, the sealing valve port pad of control media break-make, is directly connected with dynamic iron core by valve rod, and this valve is widely used in the combustion gas control and regulation of gas burner and various fuel gas nozzle and pipeline gas conveying.Mangetic core assembly is
combustionthe critical component of pneumoelectric magnet valve, requires good airproof performance, opens and closes reliable.In Cemented filling, need to be connected in series valve on pipeline.In recent years, along with the fast development of solenoid valve, and have rapid and convenient, the advantage such as remote controlled, the application of solenoid valve in pipeline increases gradually; But, in the Pipeline transport that some calibers are larger, as natural gas transport etc., because the flow in pipeline is relatively large, and existing solenoid valve is mostly single armature, in use, by a movement conducting or the disconnection delivery line of armature, because the latus rectum of pipeline is larger, when armature once opens all pipelines, flow moment sharply increases, and causes enormous impact so just can to flow monitoring equipment, time serious, even can damage monitoring equipment.CN 101956859 A disclosed " a kind of gas electromagnetic valve ", comprise valve body, valve body comprises inducer and outlet section, inducer and outlet section are cut off by dividing plate, the periphery of valve body is provided with at least two valve passages, on valve body, corresponding valve passage place is provided with for cutting off or the mangetic core assembly of the corresponding valve passage of conducting, the Returnning spring that mangetic core assembly comprises armature, covers at the guide sleeve of armature outside, is located in the coil of guide sleeve periphery and is mounted between guide sleeve and armature; Because its inducer and outlet section are cut off by dividing plate by this gas electromagnetic valve, and at least two valve passages are set in the circumferential, each valve passage arranges corresponding mangetic core assembly to control the folding of corresponding valve passage, thus progressively can open each bar valve passage, flow in transmission pipeline is progressively added up, avoid because of once completely conducting valve body inducer and outlet section and cause flow to be uprushed, and then prevent because delivery line flow is uprushed and severe impact monitoring equipment.But its mangetic core assembly can not regulate, therefore, need to be improved further.
