Description
Technical field
The utility model relates to construction engineering technical field, refers to a kind of bend pipe structure-improved of construction engineering ventilation duct especially.
Background technique
High-rise building must be provided with ventilation duct facility, to reach the ventilation ventilatory of whole solitary building, to make can not produce peculiar smell in ventilation duct, therefore without designing good ventilation duct, the air of indoor and outdoor not only can be made to circulate, cause harmful gas to fill the air in indoor, and carry the invasion and attack of rainwater secretly at high wind under, rainwater can be made to pour in down a chimney to indoor and cause the pollution such as ponding or spot, even make exhaust equipment damage and reduce working life.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of bend pipe structure-improved of construction engineering ventilation duct, to solve the technical problem.
For solveing the technical problem, embodiment of the present utility model provides a kind of bend pipe structure-improved of construction engineering ventilation duct, it is for be respectively equipped with a first ring edge and one second ring edge at the both ends open place of described bend pipe, the middle section position of described bend pipe is provided with a kink, described first ring edge axially extension is provided with a sleeve pipe, described sleeve pipe can compel to be located in the mounting hole of metope, described second ring edge is axially arranged with a constriction pipe, and be provided with a unidirectional chock plate in the bend pipe inside of contiguous second ring edge, described unidirectional chock plate comprises is located at pivoted hole on described elbow internal wall and stopper part, and activity is articulated in the valve block of described pivoted hole, described valve block is slightly less than described bend pipe internal diameter, described constriction pipe box is located in described ventilation duct, makes the position of described second ring edge higher than described first ring edge, poor to be formed with a height section.
Marine glue is provided with between described first ring edge and metope.
The beneficial effect of described technological scheme of the present utility model is as follows:
1. the utility model utilizes the bend pipe easily installed, construct, be connected between ventilation duct and mounting hole, the height section formed between ventilation duct by the kink of bend pipe is poor, block flowing when rainwater pours in down a chimney, and rainwater is discharged automatically, avoid rainwater to pour in down a chimney the damage caused to exhaust equipment along ventilation duct.
2., because the utility model first ring edge front end is provided with a sleeve pipe, can directly urgently be located in mounting hole, to remove the fixing inconvenience of screw from, easier for installation.
3. the utility model is provided with unidirectional chock plate, not only adds unidirectional effect of giving vent to anger, and can increase the effect blocking rainwater and pour in down a chimney.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model embodiment.
Fig. 2 is the cross-sectional view of the utility model embodiment.
Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, the utility model provides a kind of bend pipe structure-improved of construction engineering ventilation duct, it is the both ends open place at bend pipe 40, be respectively equipped with first ring edge 91 and an one second ring edge 92, and axial extension is provided with a sleeve pipe 911 in first ring edge 91 front end, second ring edge 92 is axially arranged with a constriction pipe 921, and be provided with a unidirectional chock plate 93 in bend pipe 90 inside of contiguous second ring edge 92, described unidirectional chock plate 93 comprises is located at pivoted hole 931 on bend pipe 90 inwall and stopper part 932, and activity is articulated in the valve block 933 of pivoted hole 931, valve block 933 is slightly less than bend pipe 90 internal diameter, the kink 94 of described bend pipe 90 middle section position is provided with two oblique angles, two oblique angles are greater than 90 degree, to form the pattern tilted.
During installation, the sleeve pipe 911 of first ring edge 91 is utilized urgently to be located in the mounting hole 51 of metope 50, first ring edge 91 relies on metope 50, and marine glue 60 is provided with between first ring edge 91 and metope 50, the necking section 921 of bend pipe 90 is sheathed on ventilation duct 70 one end, to complete the connection of ventilation duct 70 and mounting hole 51, its installations, easy construction, fast.
During use, the flowing of water is blocked by the height section difference of kink 94, and the design of described unidirectional chock plate 93, ventilation duct 70 air-flow smooth flow from inside to outside can be made, then cannot flow into externally to interior air-flow, moreover its unidirectional chock plate 93 also can stop that rainwater pours in down a chimney, and significantly promotes the effect of its waterproof.
The utility model has following advantages when implementing:
1. the utility model utilizes the bend pipe easily installed, construct, be connected between ventilation duct and mounting hole, the height section formed between ventilation duct by the kink of bend pipe is poor, block flowing when rainwater pours in down a chimney, and rainwater is discharged automatically, avoid rainwater to pour in down a chimney the damage caused to exhaust equipment along ventilation duct.
2., because the utility model first ring edge front end is provided with a sleeve pipe, can directly urgently be located in mounting hole, to remove the fixing inconvenience of screw from, easier for installation.
3. the utility model is provided with unidirectional chock plate, not only adds unidirectional effect of giving vent to anger, and can increase the effect blocking rainwater and pour in down a chimney.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
