Description
Technical field
The utility model relates to a kind of safeguard of being located in the ventilation stack, playing ventilation or blocking-up ventilation usefulness, particularly a kind of safeguard of complete assembling on ventilation stack.
Background technology
The safeguard that the cleaning type ventilation system of existing underground railway civil air defense constructions and installations is used, form by the three road airtight blast doors that are located near airshaft mouth place, first road is the protective ventilation door of band valve, and second road is the airtight blast door that sealed valve is housed, and the 3rd road is the blower fan sealed door.When the big air quantity of subway ventilated at ordinary times, three sects all were in opening, and door leaf stands on both sides.Close wartime, and in the time of need ventilating, air intake is responsible at first sect, and filter dirt is responsible at second sect, and fan starting is responsible at the 3rd sect.When shock wave or pernicious gas arrival, the ventilation valve at first sect is closed, and the sealed valve at second sect is closed, and the 3rd sect blower fan cuts out.The ventilation function of underground railway civil air defense constructions and installations is finished in three sect synergy of this equipment jointly.Its shortcoming is that three sects make that the shield segment of underground structure is longer, and civil engineering costs is higher.The structure of existing ventilation 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, this valve structure size is bigger, Heavy Weight, the pressure of the ripple that should withstand shocks, bear bump stress when closing again, closing presure is limited by valve plate, and airtight performance is relatively poor, and closing velocity is slower, can not effectively prevent the poison gas invasion, in addition, gravity vent is the plane perforate, the gravity vent area is less, and ventilation is less.
Technology contents
The utility model provides a kind of cleaning type ventilation system safeguard, and purpose is to solve the problem that cleaning type ventilation system safeguard ventilation is less, occupation of land is big, shield segment is long, reduces the engineering civil engineering costs, is convenient to maintenance management.
The utility model cleaning type ventilation system is with the technical scheme of safeguard: the airtight blast door that comprises one band ventilation opening is with the airtight blast door that blower fan is housed, wherein, the airtight blast door of band ventilation opening connects door leaf and doorframe by hinge mechanism, establish the locking link gear on the wainscot of door leaf, upper and lower side has locking head, be provided with weather strip at doorframe and door leaf intersection, door leaf is provided with ventilation opening, it is characterized in that: the anti-deflagration wave valve of sebific duct is equipped with in the outer end of ventilation opening, sealed valve is equipped with in the inner of ventilation opening, dirt catcher is equipped with in the sealed valve outside, the anti-deflagration wave valve of sebific duct has a sebific duct perpendicular to the door leaf external surface at least, and the windward side of sebific duct is parallel to the door leaf outside, and sebific duct has gravity vent on tube wall, the root of sebific duct is fixed with Sebific duct hoop, Sebific duct hoop and door leaf fixed outside.
The sebific duct of the anti-deflagration wave valve of above-mentioned sebific duct is software rubber tube or plastics collodion pipe.
Above-mentioned sealed valve is manual, electronic or hand, electric dual-purpose sealed valve.
Above-mentioned dirt catcher is oily net dirt catcher or grid filter dirt strainer.
The sealing edge of a knife perpendicular to interface is arranged between above-mentioned door leaf and the doorframe.
Above-mentioned hinge page or leaf is single hinge hinge page or leaf or two hinge hinge page or leaf.
Above-mentioned locking link gear connects horizontal drive link by handwheel, connects vertical drive link through reducer, and vertically the drive link upper and lower side connects locking head, and locking head penetrates in the axle sleeve.
The vertical jack that is provided with between above-mentioned door leaf bottom and the doorframe.
Beneficial effect: the utility model has only the twice sealed door altogether, and twice couplet on the door cooperation usefulness is finished the ventilation function of underground railway civil air defense constructions and installations jointly.The anti-deflagration wave valve of sebific duct, the moving sealed valve of torch, oily net dirt catcher are concentrated and be located on the first road door leaf, having solved in the past, the cleaning type ventilation system needs the problem of the civil engineering section of length, saved the civil engineering costs of engineering than the safeguard of forming by three sects in the past, shorten shield segment, be convenient to maintenance management; The ventilation of the anti-deflagration wave valve of sebific duct is big, and airtight performance is good, can be mounted to one with moving sealed valve of torch and oily net dirt catcher; Door leaf and doorframe are fitted evenly, and airtight measure is reliable; The utility model is installed on the cleaning type ventilation system of large-scale civil air defense constructions and installations, the forward bearing load, and the intensity height is opened at ordinary times, is convenient to ventilate; Close wartime, and it is multi-functional to integrate wave absorption, ventilation, filter dirt etc., realizes the airtight requirement of protection.Be specially adapted to the airtight protection of underground railway civil air defense constructions and installations ventilation stack.
The course of work of the present utility model: by being converted into wartime (action of closing the door) at ordinary times, earlier jack is unclamped, door leaf is pushed the state of closing the door, operate handwheel then the locking tapered end is stretched out, promote locking head and get into lockhole, make the edge of a knife of door leaf embed the adhesive tape groove, compression seal bar, and fixing door leaf.This moment, door leaf can bear the load that forward transmits.The anti-deflagration wave valve of sebific duct is closed the realization wave absorption under the shock wave effect, very little sub-fraction was leaked valve, is filtered by the back strainer, and is sealed valve and blocks, and realizes wave absorption, protection and airtight function with this.When cleaning type ventilated, the moving sealed valve of torch was opened, and carries out ventilation dust-filtering.The process of opening the door is opposite with the action of closing the door.The operation handwheel makes locking tapered end withdrawal, and locking head withdraws from lockhole, places out final position to put door leaf, and with the fixing door leaf of jack.
