Description
Technical field
The invention is related to intake closing device in a kind of pulse set, belongs to pneumatic closure techniques field.
Background technology
Intake closing device is concentrated to be generally used for such as ultra-clean medicament compartment, aseptic operating room, test chamber and cabin peculiar to vessel, its
Vent is usually mounted with locular wall, it is periodically or interim right by opening the valve plate concentrated at blow vent on intake closing device
Room air is changed, and when outdoor has harmful dusty gass, is then needed quick closedown door-plate and is cut off blow vent.
To reach quick closedown blow vent, the keying of valve plate is generally controlled using pneumatic operated valve band, but the valve plate of pneumatic operated valve control is opened and closed
Vent inside nominal diameter mostly in below 200mm.For the concentration intake closing device installed in blow vent general goal, its
Dimension of Valve Plate also requires that larger, such as adopts special large-scale pneumatic valve, not only volume is big, weight weight, take up room it is big, also
Can cause that inconvenience is installed, and the use requirement of quick closedown cannot be met, therefore limit the use occasion of such pneumatic operated valve.Its
Secondary, existing concentration intake closing device adopts a valve plate, for the valve plate of big orifice, is also accomplished by increasing valve plate chi
Very little, large-sized Dimension of Valve Plate is affected by manufacturing and install factor, and self-deformation is larger, in addition valve plate with lid arm by tight
Firmware connects, and because valve plate can not be automatically adjusted, causes the damage ring of sealing ring, therefore is difficult to keep long-time preferably sealing property,
The also easy valve plate deformation especially after by exterior vibration impact so as to which sealing property further declines.As by increasing valve plate
Thickness improves its shock resistance improving its rigidity, then need bigger driving power to realize its keying, but can not expire
The requirement of sufficient fast opening and closing.Such as valve plate is made using the light material of high intensity, then manufacturing cost is greatly improved.Further,
Concentrate intake closing device being impacted by outside, shake and the Action of Wind pressure of outside under, or indoors under Action of Wind pressure,
Valve plate opening and closing is unstable, and causes valve plate when closing to occur crack and produce air leakage phenomena, and the air for making outside gets in,
Or suddenly close the valve of unlatching, and impact personnel and equipment normally run.
The content of the invention
The purpose of the present invention is to provide a kind of compact conformation, by multiple valve plates and valve mouth structure, without the need for increasing driving moment,
Valve plate at larger-size vent can rapidly be opened and closed, low cost of manufacture, sealed reliable, with preferable anti shock and vibration
