It Kong Zhi not be for the normally closed solenoid valve for the first, second pilot gas on-off for closing it will to be pushed away under the first spool, the second spool
And normally open solenoid valve, the bottom cover are equipped with the gas outlet being connected to the first valve chamber, the exhaust outlet being connected to the second valve chamber and first
The air inlet of valve chamber connection and the exhaust passage for connecting gas outlet and the second valve chamber.
The utility model also has feature further below:
1, when the first spool is opened, air inlet is connected to gas outlet；When the first spool is closed, air inlet and gas outlet
It blocks；When the second spool is opened, gas outlet is connected to by exhaust passage and the second valve chamber with exhaust outlet；When the second spool is closed
When, gas outlet and exhaust outlet block.
2, the valve deck is provided with first, second guide's gas circuit, and the inlet end connection gas circuit of first, second guide's gas circuit is total
Wind, first, second guide's gas circuit outlet side lead to the upper end of the first spool, the second spool respectively.
3, the valve deck is provided with the reseting pressuring spring above the second spool, assists it multiple for depressing the second spool
Position.
4, the bottom cover is equipped with throttling set, can satisfy different demands, to also can guarantee disparity items bottom cover component
Interchangeability.
Compared with prior art, technical solution provided by the utility model has the following obvious advantages:
Two spools of the utility model can be respectively under the action of two solenoid valves, upper and lower high frequency mo, realize system
Inflation, pressure maintaining and the exhaust of dynamic cylinder；The bottom cover component of the utility model is equipped with throttling set, can satisfy the difference of braking system
Demand realizes the interchangeability of frame control system EP pneumatic operated valve bottom cover component.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.

Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of high frequency mo pneumatic operated valve of the present embodiment, comprising: valve body 5 is divided into about 5 two sides of valve body
Valve deck 3 and bottom cover 6,5 first valve chamber 9 of valve body and the second valve chamber 10, interior be equipped with of the first, second valve chamber are respectively used to the first valve of control
Chamber 9, the first spool 7 of 10 on-off of the second valve chamber, the second spool 8, being provided on valve deck 3 can control respectively for by the first spool
7, the normally closed solenoid valve 1 and normally open solenoid valve 2 of the first, second pilot gas on-off for closing it, bottom cover are pushed away under the second spool 8
6 be equipped be connected to the first valve chamber 9 gas outlet 12, be connected to the second valve chamber 10 exhaust outlet 13, be connected to the first valve chamber 9 into
Port and the exhaust passage for connecting gas outlet 12 and the second valve chamber 10.When the first spool 7 is opened, air inlet and gas outlet 12
Connection；When the first spool 7 is closed, air inlet and gas outlet 12 are blocked；When the second spool 8 is opened, gas outlet 12 passes through row
Gas channel and the second valve chamber 10 are connected to exhaust outlet 13；When the second spool 8 is closed, gas outlet 12 and exhaust outlet 13 are blocked.
In this example, valve deck 3 is provided with first, second guide's gas circuit, and the inlet end of first, second guide's gas circuit connects total wind
Cylinder, first, second guide's gas circuit outlet side lead to the upper end of the first spool 7, the second spool 8 respectively.As shown in Figures 1 to 3, valve deck
3 are provided with the reseting pressuring spring 4 above the second spool 8, for depressing its reset of the second spool 8 auxiliary.
The utility model has three kinds of inflation, pressure maintaining, exhaust working conditions.
Inflation: normally closed, the equal power loss of normally open solenoid valve, in Fig. 1, the first spool 7 is opened, and the second spool 8 is closed, and realizes air inlet
Mouth is connected to (gas outlet is connect with checking cylinder) with gas outlet.
Pressure maintaining: normally closed solenoid valve obtains electric, normally open solenoid valve power loss, and the first spool 7, the second spool 8 in Fig. 2 are in pass
Closed position.Air inlet and exhaust outlet separate with gas outlet.
Exhaust: normally closed, normally open solenoid valve it is electric, in Fig. 3 the first spool 7 close, the second spool 8 open, realization outlet
Mouth is connected to (exhaust outlet is directly connect with atmosphere) with exhaust outlet.
By frequently controlling normally closed, normally open solenoid valve power loss, the height of the first spool 7 and the second spool 8 may be implemented
Frequency acts, to make EP pneumatic operated valve fast aeration, Quick air-discharge.
In addition to the implementation, the utility model can also have other embodiments.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
