Abstract
The invention relates to an electromagnetic high-vacuum inflation valve. The electromagnetic high-vacuum inflation valve comprises an electromagnetic assembly, an armature, a valve element, an upper cover, a cloth clamping membrane, a membrane pressing plate, a membrane base, a filter plate, a body and the like. When the vacuum state of a vacuum system needs to be damaged and air is injected, the electromagnetic assembly is powered on, the valve element sucks the armature upwards, the gas pressure in a back pressure chamber and the gas pressure in a working gas chamber are changed, the membrane base and the cloth clamping membrane are disengaged from a pipeline opening in the body, and air entering the filter plate or an air filter is injected into the vacuum system. When the vacuum degree of the vacuum system decreases to a preset value, the electromagnetic assembly is powered off, force of an upper spring is downward, the cloth clamping membrane presses the pipeline opening in the body, and the vacuum system is closed. The electromagnetic high-vacuum inflation valve is connected into a vacuum pipeline, and the vacuum degree of the vacuum system can be damaged or controlled in time according to presetting.

Embodiment
Mode of execution below in conjunction with accompanying drawing is described in further detail the present invention:
Embodiment one
As shown in Figure 1, 2, a kind of electromagnetism high vacuum gas charging valve, it comprises electromagnetic assembled 1, upper spring 2, armature 3, spool 4, small sealing ring 5, lower spring 6, folder cloth diaphragm 7, big sealing ring 8, filter plate 9, main body 10, upper cover 11, film cloth platen 12, diaphragm seat 13 and wear-resisting plug 14.Described armature 3 is slidably matched with described spool 4, and described upper spring 2 is contained in armature 3 endoporus.
Described diaphragm seat 13 has center hole 18, and described folder cloth diaphragm 7 has little vent 15, and little vent 15 diameter is less than the diameter of the center hole 18 of described diaphragm seat 13.
Described spool 4 lower end is fixed tightly on upper cover 11, and upper cover 11 and main body 10 use screws tighten.Described folder cloth diaphragm 7 periphery is pressed between upper cover 11 and main body 10, forms back pressure chamber 16 between upper cover 11 and folder cloth diaphragm 7, forms working gas chamber 17 between main body 10 and folder cloth diaphragm 7.
Described lower spring 6 is enclosed between armature 3 lower end and described diaphragm seat 13 upper end, and folder cloth diaphragm 7 intermediate hole is enclosed within diaphragm seat 13, and film cloth platen 12 endoporus is tightly placed on diaphragm seat 13, pressing clip cloth diaphragm 7.
Described main body 10 4 side window mouth respectively tightens up one piece of filter plate 9.
The material of described wear-resisting plug 14 is abrasive rubber.
Described folder cloth diaphragm 7 material is acrylics filament canvas filler rubber, working life more than 100,000 times.
Described main body 10 material is aluminum alloy LY12.
Described filter plate 9 material is Cuprum alloy H59.
Embodiment two
As shown in Figure 3,4, the electromagnetism high vacuum gas charging valve that aeration quantity is larger, on main body 10 4 side window mouth, three faces connect air filter (not shown) one face closure, or two face connect air filter (not shown) two face closure, or one side connects air filter (not shown) three side sealing and closes.
The course of action of electromagnetism high vacuum gas charging valve is:
As shown in Figure 1,3, when electromagnetic assembled 1 dead electricity, because the elastic force of upper spring 2 pushes down diaphragm seat 13 downwards armature 3.Meanwhile, by the tension force of lower spring 6, diaphragm seat 13 to pressing down, folder cloth diaphragm 7 is forced to be close to the vacuum mouth of pipe in main body 10.Now, entered the air of working gas chamber 17 by filter plate 9, by the little vent 15 on folder cloth diaphragm 7, enter back pressure chamber 16.At this moment, air pressure above folder cloth diaphragm 7 in back pressure chamber 16, be greater than the air pressure (because the vacuum tube implication in main body 10 is forced down) of working gas chamber 17 li below folder cloth diaphragm 7, the pressure official post folder cloth diaphragm 7 of folder cloth diaphragm 7 upper and lower faces is more close to the vacuum mouth of pipe in main body 10, and vacuum system can not be leaked.
When vacuum system needs inflation, electromagnetic assembled 1 is energized, and as shown in Figure 2,4, electromagnetic attraction makes armature 3 press
Contracting upper spring 2 upwards, make wear-resisting plug 14 depart from diaphragm seat 13, ventilate, back pressure chamber by the center hole 18 of diaphragm seat 13
The air of 16 is by entering working gas chamber 17 by center hole 18.Diameter due to center hole 18 is greater than folder cloth film
The diameter of the little vent 15 on sheet 7, so the air of outflow back pressure chamber 16 is more than leaked-in air, makes back pressure cavity
The air pressure of room 16 declines rapidly, causes the air pressure of working gas chamber 17 li to exceed the air pressure of back pressure chamber 16, upwards
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 enters working gas chamber 17 from filter plate 9 or air filter, then enters
Vacuum system is inflated.
Electromagnetic assembled 1 each alternate energisation, dead electricity, make vacuum system be filled with a certain amount of air.Electromagnetism high vacuum gas charging valve of the present invention is connected in vacuum system, allocates corresponding electric apparatus control apparatus into, just can realize destroying vacuum state
Or control the automatic control of degree of vacuum.
