Brief description of the drawings
Fig. 1 is the utility model structural representation in off position；
Fig. 2 is structural representation of the utility model in opening state.
Specific embodiment
The technical solution of the utility model is described further with reference to Figure of description：
As shown in Figure 1 and Figure 2, vacuum pilot valve, including valve body 33, bonnet 31, spring 34, lower sheeting 35, upper compressing tablet 36,
Pellosil 32, air inlet K37, air inlet P38, gas outlet 39, valve body 33 are detachably connected with bonnet 31, and sky is provided with valve body 33
Chamber A1 and cavity B2, pellosil 32, spring 34 are located in cavity A1, and pellosil 32 is located between cavity A1 and cavity B2, is pushed
Piece 35 is fixed on the bottom of pellosil 32, and upper compressing tablet 36 is fixed on the top of pellosil 32, and one end of spring 34 is fixedly connected
Compressing tablet 36, the other end of spring 34 is fixed on the top of cavity B2, and air inlet K37 is fixed on bonnet 31, air inlet P38, goes out
Gas port 39 is located at the both sides of cavity B2, and air inlet K37 is connected with cavity A1, and it is empty that cavity B2 is provided with the first cavity zone 11, second
Alveolus 12, the 3rd cavity zone 13, the second cavity zone 12 are located between the first cavity zone 11 and the 3rd cavity zone 13, the second cavity zone
12 are provided with opening 121, and the first cavity zone 11, the 3rd cavity zone 13 are all connected by opening 121 with the second cavity zone 12, silica gel
Film 32 is also located at the top of opening 121.Cavity A1 is located at the top of cavity B2.Air inlet K37 is located at the surface of spring 34.Enter
Gas port P38 is located at the right side of cavity B2, and gas outlet 39 is located at the left side of cavity B2.Bonnet 31 is located at the top of valve body 33.Air inlet
Mouth P38 is connected with the first cavity zone 11, and gas outlet 39 is connected with the 3rd cavity zone 13.
As shown in figure 1, air inlet P38 is passed through negative-pressure air-flow, and in the enterprising gas port K37 access failure high vacuum of bonnet 31, silicon
Glued membrane 32 is at spring 34 and cavity B2 with the presence of the collective effect of high negative pressure so that pellosil 32 is moved downward, and is close to opening
121, vacuum pilot valve is closed.
As shown in Fig. 2 air inlet P38 is passed through negative-pressure air-flow, when the enterprising gas port K37 of bonnet 31 connects high pressure vacuum, this
When the top large area of pellosil 32 and the product of negative pressure pressure produced by power, overcome spring 34 and the bottom facet of pellosil 32
Power produced by the product of product and negative pressure pressure, pellosil 32 is moved upwards so that pellosil departs from opening 121, the first cavity
Area 11, the second cavity zone 12, the 3rd cavity zone 13 are all connected, and vacuum pilot valve is open-minded, the outflow of gas outlet 39 negative-pressure air-flow.Because true
The area that empty pilot valve opens the upper and lower part of rear pellosil 32 is identical, air inlet P38 is passed through negative-pressure air-flow, now cavity B2
Vacuum pressure becomes very little, and its suction is much smaller than cavity A1, therefore vacuum pilot valve is still in opening state, when bonnet 31 is enterprising
When gas port K37 connects air, air inlet K37 and atmosphere, vacuum pilot valve in the presence of cavity of resorption vacuum, vacuum solenoid
Return to closed mode.
The utility model is the vacuum for realizing controlling big flow with low discharge vacuum, very easy to use, can be used in
The neonate of Stress control, hospital to negative pressure of vacuum attracts, waste gas of anesthesia attracts discharge, oral cavity attraction, other negative pressure of hospital
The place, the utility model valve body 33, bonnet 31, spring 34, lower sheeting 35, upper compressing tablet such as the pressure of flow diverter and switch control
36th, pellosil 32, air inlet K37, air inlet P38, gas outlet 39, its number of structures and species are few, therefore the utility model knot
Structure is simple, low cost.
It should be noted that listed above is only a kind of specific embodiment of the present utility model.Obviously, the utility model
Above example is not limited to, there can also be many deformations.
In a word, the institute that one of ordinary skill in the art can directly derive from the utility model disclosure or associate
There is deformation, be considered as protection domain of the present utility model.
