Embodiment
Embodiment below in conjunction with the accompanying drawings is described in further detail to the present invention：
Embodiment one
As shown in Figure 1, 2, a kind of electromagnetism high vacuum charge valve, it include electromagnetic assembled 1, upper spring 2, armature 3, valve element 4,
Small sealing ring 5, lower spring 6, folder cloth diaphragm 7, large sealing packing ring 8, filter 9, main body 10, upper lid 11, film cloth platen 12, diaphragm seat
13 and it is wear-resisting plug 14.The armature 3 is slidably matched with the valve element 4, and the upper spring 2 is mounted in the endoporus of armature 3.
The diaphragm seat 13 has centre bore 18, has small passage 15 on the folder cloth diaphragm 7, the small diameter of passage 15 is less than
The diameter of the centre bore 18 of the diaphragm seat 13.
The lower end of valve element 4 is fixed tightly on lid 11, and upper lid 11 uses screws tighten with main body 10.The folder cloth diaphragm 7 weeks
While being pressed between lid 11 and main body 10, back pressure chamber 16, main body 10 and folder cloth film are formed between upper lid 11 and folder cloth diaphragm 7
Working gas chamber 17 is formed between piece 7.
The lower spring 6 is enclosed between the lower end of armature 3 and the upper end of diaphragm seat 13, and the interstitial hole of folder cloth diaphragm 7 is enclosed on film
On bar 13, the endoporus of film cloth platen 12 is tightly placed on diaphragm seat 13, pressing clip cloth diaphragm 7.
One piece of filter 9 of each fastening on the side window mouth of main body 10 4.
The material of the wear-resisting plug 14 is abrasive rubber.
The material of folder cloth diaphragm 7 is acrylics filament canvas filler rubber, service life more than 100,000 times.
The material of main body 10 is aluminium alloy LY12.
The material of filter 9 is copper alloy H59.
Embodiment two
As shown in Figure 3,4, the larger electromagnetism high vacuum charge valve of aeration quantity, on the side window mouth of main body 10 4, three faces connect sky
Air filter（Do not show in figure）One face closure, or two faces connect air cleaner（Do not show in figure）Two face closures, or one side connect air
Filter（Do not show in figure）Three side sealing closes.
The action process of electromagnetism high vacuum charge valve is：
As shown in Figure 1,3, when 1 dead electricity of electromagnetic assembled, due to upper spring 2 elastic force armature 3 downwardly against diaphragm seat
13.Meanwhile by the tension force of lower spring 6, diaphragm seat 13 is pressed downward, forces folder cloth diaphragm 7 to be close to the vacuum mouth of pipe in main body 10.
Now, the air of working gas chamber 17 is entered by filter plate 9, by pressing from both sides the small passage 15 on cloth diaphragm 7, into back pressure chamber
16.At this moment, air pressure of the cloth diaphragm 7 above in back pressure chamber 16 is pressed from both sides, more than in folder cloth diaphragm 7 below working gas chamber 17
Air pressure（Because the vacuum tube implication in main body 10 is forced down）, the pressure official post folder cloth diaphragm 7 of the upper and lower faces of folder cloth diaphragm 7
The vacuum mouth of pipe being more close in main body 10, makes vacuum system not leak.
When vacuum system needs inflation, electromagnetic assembled 1 is powered, and as shown in Figure 2,4, electromagnetic attraction presses armature 3
Spring 2 is upward in contracting, wear-resisting plug 14 is departed from diaphragm seat 13, the centre bore 18 of diaphragm seat 13 is ventilated, back pressure chamber
16 air by centre bore 18 by entering working gas chamber 17.Because the diameter of centre bore 18 is more than folder cloth
Film
The diameter of small passage 15 on piece 7, so the air of outflow back pressure chamber 16 is more than leaked-in air, make back pressure
Chamber
The air pressure dramatic decrease of room 16, the air pressure in working gas chamber 17 is caused to exceed the air pressure of back pressure chamber 16, to
On
Air pressure add the pulling force of lower spring 6, make dynamic diaphragm seat 13 together with folder cloth diaphragm 7 upwards, folder cloth diaphragm 7 departs from
The vacuum mouth of pipe in main body 10, air enter working gas chamber 17, Ran Houjin from filter 9 or air cleaner
Enter
Vacuum system is inflated.
1 each alternate energisation of electromagnetic assembled, dead electricity, make vacuum system be filled with a certain amount of air.The electromagnetism of the present invention
High vacuum charge valve is connected in vacuum system, is incorporated corresponding electric apparatus control apparatus, it is possible to is realized and is destroyed vacuum state
Or control automatically controlling for vacuum.
