Abstract
The present invention relates to a columnar explosion wave prevention valve. The valve body is formed by a fixed cylinder body and a movable sleeve which are in tight sleeve joint; the wall of the fixed cylinder body and the wall of the movable sleeve have ventilation holes which are in an axial staggered arrangement; at least one convex peg which is perpendicular to the wall of the fixed cylinder body is fixed to the wall of the fixed cylinder body; the convex peg passes through a corresponding axial guiding elongated slot of the movable sleeve; the external end of the movable sleeve is at least one axial pitch higher than the fixed cylinder body and radially slides within the range of the length of the guiding elongated slot; the external end of the movable sleeve is connected with a wave collecting cover, and at least one elastomer is connected between the wave collecting cover and the fixed cylinder body. The present invention solves the problem that the area of ventilation holes in the plane of a ventilation system is small, and automatically prevents the invasion of nuclear shockwaves and toxic gases. The present invention can be applied to equipment used in civil air defense engineering, equipment used in subway engineering or other equipment, meets the operation requirements of ventilation and effectively prevents the invasion of the nuclear shockwaves and the toxic gases, so that safety and normal work of inside people and equipment are ensured.
Description
Technical field
The present invention relates to a kind of protection obturator, particularly a kind of airtight valve of protection that is used for ventilating system, anti-deflagration wave.
Background technology
In ventilating system, air vent need be closed with anti-deflagration wave valve in wartime, to prevent the invasion of shock wave or poison gas, existing anti-deflagration wave valve is the formula of dangling, and by the upper end of hinge page fixing valve plate, the valve plate bottom is unsettled at ordinary times opens, expose the air vent on the plane, be beneficial to ventilated.Meet wartime, the valve plate bottom is impacted by shock wave, closes air vent, and is closed at the air outlet place by valve.This valve structure size is bigger, Heavy Weight, the pressure of the ripple that should withstand shocks bears bump stress when closing again, closing presure is limited by valve plate, airtight performance is relatively poor, and closing velocity is slower, can not effectively prevent the poison gas invasion, in addition, air vent is the plane perforate, and the air vent area is less, and ventilation is less.
Summary of the invention
The purpose of this invention is to provide the anti-deflagration wave valve of a kind of cylindricality, it is less to solve ventilating system plane air vent area, and the ventilation problem of smaller prevents the intrusion of nuclear shockwave and toxic gas effectively, fast and automatically.
The technical scheme of the anti-deflagration wave valve of cylindricality of the present invention: comprise a body, it is characterized in that: the door body is by in fixed cylinder and the quill, closely be socketed to form outward, have the air vent of axial interlaced arrangement on the barrel of fixed cylinder and quill, at least be fixed with a protruding short wooden stake vertical on the barrel of fixed cylinder with barrel, it passes from the axial guiding elongated slot of the quill of correspondence, the outer end of quill exceeds at least one axial hole distance of fixed cylinder, and in the length range of guiding elongated slot, endwisely slip, the outer end of quill is connected with wave collecting cover, is connected at least one elastomer between wave collecting cover and the fixed cylinder.
The air vent of said fixing cylindrical shell and quill is bar hole, circular port, polygonal hole or grill-shaped hole.
The air vent of above-mentioned quill is a blind hole.
Above-mentioned protruding short wooden stake is guider screw, guide blot or guiding button.
Above-mentioned elastomer is return spring, reed or Sponge.
Above-mentioned elastomer and wave collecting cover are that welding, bonding or bolt are connected.
Above-mentioned wave collecting cover is flat cover, umbrella hood or the bottom of a pan shape cover.
Said fixing cylindrical shell inner end connects the airtight plate vertical with barrel.
The peripheral fixedly connected ring flange of said fixing cylindrical shell.
Above-mentioned elastomeric the inner is connected the outer face of fixed cylinder or is connected on the ring flange of fixed cylinder, and elastomeric outer end directly is connected with wave collecting cover or is connected with wave collecting cover indirectly through quill.
Beneficial effect: the anti-deflagration wave valve structure of cylindricality is simple, and airtight performance is good, and air vent opens and closes freely, can prevent effectively that toxic gas from entering in the engineering.The air vent of the anti-deflagration wave valve of cylindricality is opened on column-shaped barrel, its draught area equates with ventilation duct road junction draught area, be fullest to utilize conduit section, radial dimension be minimum in all valve, therefore be well suited for being used for the big and ventilating system of the subway that size is little of requirement ventilation; Adopt the wave collecting cover structure in addition, closing presure is increased, shortened the shut-in time, so the attenuating shock wave ratio height.Valve adopts metal or plastic material to make, and stable performance does not have aging.
The course of work of the present invention: the fixed cylinder of the anti-deflagration wave valve of cylindricality is fixed in the air vent air inlet place of protective door, can be fixed by ring flange, and electronic or manual plate airtight valve can be installed by air vent air outlet place.Anti-deflagration wave valve of cylindricality and airtight valve all are in opening at ordinary times, and the air vent of fixed cylinder and quill aligns coincidence, and outside fresh air can be sent into inside by air vent, realize that cleaning type ventilates; When being subjected to nuclear shockwave or gas attack, wave collecting cover is under the shock wave pressure effect, compresses elastomeric, and drive quill and endwisely slip along guiding elongated slot relative fixed cylindrical shell, at this moment, the air vent of fixed cylinder and quill is staggered state, thereby shutoff air vent, air vent can be closed automatically, and shock wave is blocked in outside the protective door, and the opposing nuclear shockwave attacks.Internal staff and equipment are protected.Before outside air is not contaminated, in time promptly blower fan and airtight valve are closed, can realize that isolation type ventilates.After war, wave collecting cover restores to the original state under the effect of elastomeric elastic restoring force, and air vent is coincidence status again.This system is used for the ventilation in wartime in the subway, can be applicable to civil air defense constructions and installations, subway engineering or miscellaneous equipment, satisfies the instructions for use of ventilating, and effectively prevents the intrusion of nuclear shockwave and toxic gas, guarantees the safety and the operate as normal of internal staff and equipment.
