Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1 and Figure 2, a kind of combined type air valve of the utility model, it comprises valve body 1 and electromagnetic coil assembly two-part, described valve body 1 is provided with first suction port 18, second suction port 19 and pore 17 and inflation inlet 21, and described first suction port 18, second suction port 19 and pore 17 are interconnected; Described inflation inlet 21 is communicated with first suction port 18 and second suction port 19 by pore 17, also is that gas enters valve body 1 from first suction port 18 or second suction port 19, just can enter inflation inlet 21 behind pore 17, flows out outside the valve body 1 from inflation inlet 21 again.The internal diameter of the external diameter of described second suction port 19 and first suction port 18 is complementary, and this is mainly interconnecting between convenient a plurality of combined type air valves.Valve body 1 can be made by metallic material or hard plastics, and is generally one-body molded by mould.
The bottom of described valve body 1 is provided with circular valve seat 23, described pore 17 is located in the circular valve seat 23, circular valve seat 23 peripheries are fixedlyed connected with sealing gasket 10, liner plate 2, pressing plate 6 and electromagnetic coil assembly successively through retaining screw 22, be provided with relief opening 16 between described liner plate 2 and the pressing plate 6, be provided with noise reduction sponge 13 in the described relief opening 16, this is in the process of exhaust, and noise more farthest reduces, and helps optimizing working environment.
Described electromagnetic coil assembly comprises support arm 7, is lining in the coil brace 3 in the support arm 7, the described coil brace 3 outer coils 15 that are tied with, and for improving Safety performance of the present utility model effectively, described coil 15 outsourcings are provided with insulation layer of cloth 14, take place to avoid the electric leakage situation.Form cavity (not indicating among the figure) in the coil brace 3, cavity and pore 17 are located along the same line, cavity bottom is fixed with fixed core 5, fixed core 5 is provided with moving unshakable in one's determination 4, be provided with spring 8 between the described fixed core 5 and moving unshakable in one's determination 4, described moving 4 tops unshakable in one's determination are provided with rubber chock plug 9, described rubber chock plug 9 positions are corresponding with pore 17 positions, the seal ring 11 that position, described moving 4 middle and upper part unshakable in one's determination fixed cover is provided with, the position of described seal ring 11 is corresponding with the position of liner plate 2, for seal ring 11 and liner plate 2 are fitted in movement process better, described liner plate 2 is provided with the inclined-plane with the one side that seal ring 11 contacts.Described seal ring 11 is divided into upper plenum and following cavity with liner plate 2 with coil brace 3 inner cavities.
For further increasing the firm degree of seal ring 11 on moving unshakable in one's determination 4, the utility model is preferably offered a draw-in groove (not indicating among the figure) in moving position, 4 middle and upper part unshakable in one's determination, and seal ring 11 fixed card are located in the draw-in groove.
When using this practicality new, gas is entered by first suction port 18 or second suction port 19, the rubber chock plug of being located at this moment on moving unshakable in one's determination 49 seals with pore 17 owing to the effect of spring 8, and in this state, inflation inlet 21 and relief opening 16 all do not have gas and flow out.After waiting to connect power supply, coil 15 energisings, thereby produce magnetic field in coil 15, moving unshakable in one's determination 4 move downward under the action of a magnetic field, and rubber chock plug 9 is separated with pore 17, gas enters in the upper plenum from pore 17, in moving 4 processes that move downward unshakable in one's determination, seal ring 11 closely contacts with liner plate 2 inclined-planes, sealing relief opening 16, this moment, gas flowed out from inflation inlet 21, was in inflated condition.At this moment, as deenergization, moving unshakable in one's determination 4 under the restoring force effect of spring 8, moves upward, and rubber chock plug 9 seals once more with pore 17, and opens between seal ring 11 and liner plate 2 inclined-planes, and gas is discharged from relief opening 16.
As mentioned above, the internal diameter of the external diameter of second suction port 19 and first suction port 18 is complementary.As shown in Figure 3, a kind of combined type air valve of the utility model can compoundly use, promptly join end to end and connect by second suction port 19 and first suction port 18, several combinations formula air valve is ganged up mutually, described second suction port 19 is outer to be provided with O RunddichtringO 12, mainly is to reach the better seal effect when interconnecting for two above combined type air valves.When several combinations formula air valve interconnects, can control the on off state of each air valve by the control power supply, can effectively form the multichannel pipeline.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
