Embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technological scheme of the present invention in detail.
Embodiment
As shown in Figure 1 to Figure 3, the three-way magnetic valve that the present invention is applied in the aircraft oxygen concentrator system comprises coil 1, valve casing 2, often open plug 3, sealing gasket 4, fixed core 5, right cover plate 6, valve body 7, left cover 8, the first spring 9, first adjusts pad 10, the second spring 11, normally closed plug 12, armature 13, second adjusts pad 14, support 15 and valve gap 16, coil 1 is positioned at the inboard of valve casing 2, sealing gasket 4 and coil 1, valve casing 2, fixed core 5 is fitted, right cover plate 6 is often being opened between plug 3 and the sealing gasket 4, valve body 7 is positioned at the downside of valve casing 2, left cover 8 is positioned at a side of valve body 7, the first spring 9 is clipped between normally closed plug 12 and the support 15, first adjusts pad 10 between normally closed plug 12 and armature 13, normally closed plug 12 and armature 13 are threaded, the second spring 11 is clipped in often to be opened between plug 3 and the normally closed plug 12, second adjusts the side that pad 14 is positioned at support 15, valve gap 16 is between support 15 and coil 1, and support 15 is fixed on the valve body 7.Armature 13, often open plug 3, normally closed plug 12, first and adjust pad 10, the second spring 11 and sealing gasket 4 and form movable valve plugs.Interference fit between fixed core 5 and the valve casing 2, often the opening valve mouth E and often open plug 3 and keep certain gap of fixed core 5.Movable valve plug and fixed core all adopt anticorrosion magnetically soft alloy bar to process through turning, and valve gap and valve casing all adopt anticorrosion magnetically soft alloy material (model is 17-4PH) bar to process.The distance of the working gas gap between normally closed plug and the armature is regulated by the first length of adjusting pad adjustment movable valve plug.The first spring is big spring, and the second spring is little spring, and the first adjustment pad is the whole pad of ditty, and the second adjustment pad is to adjust greatly pad.The three-way magnetic valve that the present invention is applied in the aircraft oxygen concentrator system is being not less than-55 ℃, is not higher than the gas that can seal 0.4MPa in 70 ℃ of scopes; And valve can be opened when the 24V dc voltage, and valve can not burnt during the 32V dc voltage.And valve can be opened when the 24V-32V dc voltage, and valve can not burnt during the 32V dc voltage.The diameter of the diameter of often opening valve mouth E of fixed core and the normally closed valve mouth D of left cover is Φ 2.2mm, the fillet of 0.2mm falls at the edge, can reduce sealing force on sealing surface place medium active force and the sealing surface, can reduce the sealing gasket wearing and tearing simultaneously, improve life of product.
As shown in Figure 2, the bottom surface of valve body has normally closed suction port A and often drives gas port B into, and the side of valve body has relief opening C.
As shown in Figure 3, the valve body intermediate portion is followed relief opening C UNICOM, but seals to external world.The movement of moving iron core realizes often opening the switching of plug 3, normally closed plug 12 and valve mouth sealing relationship, and then realizes the switching of suction port and relief opening connected relation.Original state, the first spring 9 is in compressive state, its spring force holds out against normally closed plug 12, normally closed valve mouth D sealing, normally closed suction port A is not communicated with relief opening C, though and at this moment the second spring 11 be in compressive state, but often open plug because of the restriction of armature 13 shoulder blocks, fail to touch Chang Kaiduan valve mouth E, also namely often drive gas port B and relief opening C UNICOM into, realize intake and exhaust.When the present invention is applied in three-way magnetic valve powered operation in the aircraft oxygen concentrator system, the three-way magnetic valve energising that the present invention is applied in the aircraft oxygen concentrator system produces electromagnetic force, it overcomes the effect of the first spring 9, iron core is moved, until prop up till the fixed core 5, this often beginning valve mouth with often open plug and contact, under the effect of the second spring 11, the sealing of Chang Kaiduan valve mouth, often driving gas port B into is not communicated with relief opening C, opposite normally closed suction port A has realized being communicated with relief opening C, realizes intake and exhaust, thereby satisfies the switching requirement of oxygen concentrator confession/exhaust.
As shown in Figure 3 and Figure 4, the adhesive face of armature F is provided with gas guide groove 17, determines the gas guide groove size by flow rate calculation, and its size directly affects the flow of three-way magnetic valve, realizes the exhaust of three-way magnetic valve by gas guide groove.Guiding gutter makes things convenient for gas to flow out, and realization is communicated with relief opening C's.
As shown in Figure 5, the centre of fixed core 5 is provided with pod apertures 18, makes things convenient for gas to flow out.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, the present invention has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
