Working principle:
The vacuum generator vacuum breakdown device of vacuum of the utility model, tool is there are three types of working condition: i.e. vacuum generating state,
Vacuum hold mode and vacuum breaking state.Air control switch valve M is controlled by the pressure in control chamber C, and air control switch valve M control is true
Sky generates the opening and closing of valve port between chamber V3 and vacuum interface chamber V2；Pilot valve G is by the pressure (pilot valve in pilot valve control chamber H
Pressure in control chamber H is controlled by pilot solenoid valve component 2, and conductive electromagnetic valve component 2 is opened in the ban, and gas circuit is opened, toward pilot valve
Pressurization in control chamber H) control, pilot valve G control gas supply port P and the opening and closing for destroying valve port between the A1 of channel.
Original state after installation:
Vacuum interface chamber V2, destruction outlet chamber V1, destruction channel A1, throttling passage A2 is communicated with atmosphere, is zero-pressure.
Vacuum generates chamber V3, control chamber C zero-pressure, and air control switch valve M is closed；It supplies port P and introduces operating pressure, pilot valve control chamber H
Zero-pressure, pilot valve G are closed.
Vacuum generating state:
As shown in fig. 6, control chamber C input control air pressure, control pressure acts on the end face of slide cores 51, pushes slide cores
51 compression slide cores springs 52 move downward, and air control switch valve M is opened.It destroys between outlet chamber V1 and throttling passage A2 and is broken
It opens, vacuum generates chamber V3 and is connected to vacuum interface chamber V2, and vacuum generates chamber V3 supply vacuum pressure, generates vacuum interface chamber V2
Negative pressure, vacuum interface chamber V2 can be with absorbent bodies at this time.
Vacuum hold mode:
As shown in fig. 7, after vacuum interface chamber V2 absorbent bodies, ideally, it is assumed that the pressure of vacuum interface chamber V2
Amount of leakage is 0, then can remove the control pressure of control chamber C input to save the energy consumption that vacuum generates at this time, make gas
Control switch valve M is closed and vacuum is truncated and generates contacting for chamber V3 and vacuum interface chamber V2.After air control switch valve M is closed, vacuum is connect
Oral cavity V2, destruction outlet chamber V1, destruction channel A1, throttling passage A2 are communicated, but destroy quilt between channel A1 and gas supply port P
Pilot valve G truncation, no pressure are released path；Vacuum interface chamber V2 keeps vacuum state.Object is still attracted to vacuum at this time
Hub cavity V2 can follow vacuum interface chamber V2 to be handled upside down.
Vacuum breaking state:
Under working condition, the gas compression guide valve spring 33 of gas supply port P makes pilot valve core 32 move right, guide
Valve G is closed, and gas supply port P is separated with destruction channel A1's.As shown in figure 8, when object reaches designated position, pilot solenoid valve
Component 2 receives control signal, starts pilot solenoid valve component 2, and pilot valve control chamber H is made to pressurize, and pilot valve G is opened.Supply end
Mouth P pressure is transmitted to vacuum interface chamber V2 by pilot valve G, destruction channel A1, throttling passage A2, destruction outlet chamber V1, in this way
Just the vacuum environment between object and vacuum interface chamber V2 is destroyed.Vacuum state, which is destroyed, puts down object, can break at this time
It opens pilot solenoid valve component 2 and controls signal, make product recovery original state.
The most preferred embodiment of the utility model has illustrated, the various change or remodeling made by those of ordinary skill in the art
All without departing from the scope of the utility model.
