Description of the drawings：
Fig. 1 is blow valve tomograph of the present invention.
Fig. 2 is blow valve section plan of the present invention.
Fig. 3 is the structure chart of the first valve deck in blow valve of the present invention.
Fig. 4 is the structure chart of first and second diaphragm unit in blow valve of the present invention.
Specific embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, magnetic suspension air blower of the present invention two-stage guide's blow valve, including the first valve deck 21, second
Valve deck 22, bi-bit bi-pass normally open solenoid valve 3, primary diaphragm component 41, secondary diaphragm component 42 and equipped with inlet chamber 11 and outlet
The valve body 1 of chamber 12, the first valve deck 21 lid are closed on the outlet chamber 12 of valve body 1, and primary diaphragm component 41 is fixedly connected with the first valve deck
21 with the junction of valve body 1, and primary diaphragm component 41 is covered on the outlet chamber 12 of valve body 1.Second valve deck 22 lid closes
On the first valve deck 21, secondary diaphragm component 42 is fixedly connected on 22 junction of the first valve deck 21 and the second valve deck.Bi-bit bi-pass
The control terminal of normally open solenoid valve 3 is connected with the second valve deck 22, and controls secondary diaphragm component 42 in the second valve deck and the first valve deck
Junction move up and down.
With reference to Fig. 3, the first valve deck 21 in the present invention has a body 210, and enterprising air cavity is equipped on the body 210
211st, lower inlet chamber 212 and circular air inlet duct 213, enterprising air cavity 211 are arranged on the lower end of lower inlet chamber 212, and air inlet duct 213 is set
In the outside of enterprising air cavity 211, enterprising air cavity 211, lower inlet chamber 212 and circular air inlet duct 213 on body 210 are respectively positioned on
Coaxial direction.Venthole 214 is equipped in circular air inlet duct 213, lower inlet chamber 212 passes through the ventilation with circular air inlet duct 213
Hole 214 connects；Be equipped with venthole 215 on the side wall of body 210, the venthole 215 be located at circular air inlet duct 213 under into
Between air cavity 212, enterprising air cavity 211 connects with venthole 215.Primary diaphragm component 41 in the present invention is placed in outlet chamber 12
Between lower inlet chamber 212, secondary diaphragm component 42 is placed between enterprising 211 and second valve deck 22 of air cavity.
Such as Fig. 4, primary diaphragm component 41 and secondary diaphragm component 42 in the present invention include top plate 100, lower plywood
101st, diaphragm 102 and bolt 103, diaphragm 102 are fixed on by bolt 103 between top plate 100 and lower plywood 101.Wherein, on
The area of laminate 100 is more than the area of lower plywood 101.
When bi-bit bi-pass 3 dead electricity of normally open solenoid valve, the gas pressure of the epicoele of secondary diaphragm component 42 is zero (i.e. second
Gas pressure in 22 inner cavity of valve deck is that zero), gas pressure in lower inlet chamber 212 is by venthole 214 by secondary diaphragm group
Part 42 jacks up exhaust, and enterprising air cavity 211 connects with lower inlet chamber 212 at this time, and the gas pressure in lower inlet chamber 212 reduces,
Since enterprising air cavity 211 is connected with lower inlet chamber 212, so the epicoele upper cavity pressure of primary diaphragm component 41 also reduces simultaneously
(descending the gas pressure in inlet chamber 212).The pressure of inlet chamber 11 jacks up primary diaphragm component 41 at this time, and valve emptying is put
Gas.
When bi-bit bi-pass normally open solenoid valve 3 must be electric, the gas pressure of the epicoele of secondary diaphragm component 42 rises (i.e. second
Gas pressure in 22 inner cavity of valve deck rises), when the surface pressure up and down of secondary diaphragm component 42 is equal, due to secondary diaphragm group
The forced area of 42 upper surface of part is more than the forced area of lower surface, so secondary diaphragm component 42 is depressed and seals upper air
Chamber 211.At this point, the pressure in lower inlet chamber 212 rises, when the upper and lower surface pressure of primary diaphragm component 41 is equal, due to
The forced area of 41 upper surface of primary diaphragm component is more than the forced area of lower surface, so, primary diaphragm component 41 is depressed
And close outlet chamber 12.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, several improvement can also be made without departing from the principle of the present invention, these improvement also should be regarded as the present invention's
Protection domain.
