Abstract
The utility model discloses an electromagnetic three-way change valve, comprising a main valve, a pilot valve positioned on the main valve and connected with the main valve through an air chamber; wherein, the pilot valve comprises a pilot valve body which is provided with an air inlet and an air passage to the air chamber, an iron core positioned between the air passage and the air inlet of the pilot valve, and an electromagnetic coil. The utility model is characterized in that the gas flow direction in the output pipe can be changed according to the power on and power off of the electromagnetic coil. The utility model has the advantages of simple structure, quick and reliable switching and convenient assembling, being suitable for the diversion of a plurality of kinds of gases.
Description
Technical field
The utility model relates to a kind of gas commutating valve, particularly a kind of electromagnetism three-way diverter valve.
Background technique
At present for the needs of gas commutation, using gases distributing valves all, its complex structure, no pilot valve can not automatic reverse, needs configuration separately, therefore to using and installation is made troubles.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure for the deficiency that solves above-mentioned technology, and switching is rapid, reliable, a kind of electromagnetism three-way diverter valve easy for installation.
In order to achieve the above object, a kind of electromagnetism three-way diverter valve that the utility model is designed, it comprises main valve, is provided with pilot valve on main valve, main valve and pilot valve are by the air chamber combination.Described pilot valve can be made up of guide's valve body, iron core and electromagnetic coil, is provided with pilot valve suction port and the gas circuit of leading to air chamber on the pilot valve body, and iron core is located between gas circuit and the pilot valve suction port.Be provided with spring between electromagnetic coil and the iron core.Fix by jump ring between guide's valve body and the main valve body.Be provided with on diaphragm, at one end the diaphragm at the two ends of main valve body and be provided with end cap, be provided with spring between end cap and the diaphragm.Be provided with central shaft in the main valve, the two ends of central shaft are connected with diaphragm respectively.
The resulting a kind of electromagnetism three-way diverter valve of the utility model, it is simple in structure, and switching is rapid, reliable, and easy to installation and maintenance, it is suitable for the usefulness of all gases commutation.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, a kind of electromagnetism three-way diverter valve that present embodiment is described, it comprises main valve 18, is provided with pilot valve 17 on main valve 18, main valve 18 and pilot valve 17 are by air chamber 10 combinations.Described pilot valve 17 is made up of guide's valve body 4, iron core 11 and electromagnetic coil 3, is provided with pilot valve suction port 12 and the gas circuit 19 of leading to air chamber 10 on pilot valve body 4, and iron core 11 is located between gas circuit 19 and the pilot valve suction port 12.Be provided with spring 8 between electromagnetic coil 3 and the iron core 11, fixing between guide's valve body 4 and the main valve body 5 by jump ring 9.On main valve body 5, be provided with diaphragm 1, diaphragm 2, be provided with end cap 6, be provided with spring 7 between end cap 6 and the diaphragm 2 at diaphragm 2.Be provided with central shaft 16 in main valve 18, the two ends of central shaft 16 are connected with diaphragm 2 with diaphragm 1 respectively.
In the working procedure, when electromagnetic coil 3 gets, iron core 11 is attracted and moves right, pressure spring 8, thus pilot valve suction port 12 opened, make pilot valve air chamber 10 gassies, the pressure of this gas makes diaphragm 1 to left movement, rely on central shaft 16 related diaphragms 2 also to left movement, thereby make diaphragm 1 close relief opening 13, diaphragm 2 is opened suction port 14.This moment because of the pressure of suction port 14 greater than delivery outlet 15, make gas flow to delivery outlet 15 from suction port 14.During dead electricity, iron core 11 loses suction by spring 8 tops left, thereby closes pilot valve suction port 12, and pilot valve air chamber 10 pressure are reduced.This moment, spring 7 pushed up diaphragm 2 to the right, relied on central shaft 16 related diaphragms 1 also to move right, thereby closed suction port 14 by diaphragm 2, and diaphragm 1 is opened relief opening 13.At this moment, because of the pressure of delivery outlet 15 greater than relief opening 13, make gas flow to relief opening 13 from delivery outlet 15.
