Abstract
The utility model discloses a three-way device of a smoke discharge pipeline. The three-way device is mounted between the indoor exhaust equipment on each floor and a building exhaust main pipeline, and comprises a vertical main pipe and a horizontal branch pipe; the main structure is that a vertical guide plate is mounted at the joint between the vertical main pipe and the horizontal branch pipe; an obliquely-arranged exhaust check valve is mounted at the middle section of the horizontal branch pipe; the exhaust check valve consists of a movable plate and a clamp piece in cooperation; the upward side of the movable plate is hinged with the clamp piece; the left, right and bottom sides are in clamp joint with the clamp piece. When indoor smoke is discharged, a positive pressure is formed in the horizontal branch pipe, and the light movable plate of the exhaust check valve is opened toward the vertical main pipe; when no indoor smoke is discharged, the movable plate falls under self-weight and clings to the clamp piece; when the smoke returns, a negative pressure is formed in the horizontal branch pipe, the movable plate is locked with the clamp piece, and thus the gas in the exhaust main pipe is prevented from entering inside. The device disclosed by the utility model has the advantages of simple structure, smooth exhaust and high universality and can prevent odor tainting in indoor smoke and gas discharge.
Description
Technical field
The utility model relates to a kind of three-way device, refers in particular to the three-way device being connected with the vertical exhaust duct of building for washroom, kitchen exhauster.
Background technology
Along with the raising of living standards of the people and the improvement of habitat condition, society is more and more higher to the requirement of Humanizing of architecture design.But in some high residential buildings, the taint of odour phenomenon of kitchen, washroom seems particularly outstanding at present.Domestic some high-grade lampblack absorber, exhaust blower are provided with similar device, but complex structure, and cost is high, is difficult for extensively promoting.Therefore, study that a kind of cost is low, highly versatile, the smoke discharging pipe non-return three-way device that do not need to increase user cost be necessary.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of smoke discharging pipe three-way device, this device is arranged between indoor exhaust wind equipment and the vertical exhaust duct of building, can guarantee at any time that indoor fume emission is smooth and easy, and in blocking-up building exhaust duct, smoke backflow enters indoor passage, thereby reach the object that each floor gap flue gas is not gone here and there mutually.
The technical problems to be solved in the utility model is realized by following scheme: smoke discharging pipe three-way device, be arranged between every layer of indoor exhaust wind equipment and building air draft main pipeline, comprise vertical supervisor, horizontal branch pipe, it is characterized in that: described vertical supervisor and horizontal branch pipe junction are provided with vertical deflector, described horizontal branch pipe stage casing is provided with the air draft non retern valve being in tilted layout, air draft non retern valve is by portable plate and fastener mix proportion, portable plate top and fastener chain connection; Left and right, base and fastener clamping.
The utility model also comprises following scheme: described air draft non retern valve is arranged on horizontal branch pipe stage casing, becomes 80 degree angles with horizontal branch pipe.Described portable plate is arranged on one side near vertical supervisor, and described fastener is arranged near an indoor side.The bottom margin of described vertical deflector is in vertical supervisor and below horizontal branch pipe node bottom margin.
Operating principle of the present utility model is: when indoor flue gas is discharged, form malleation in horizontal branch pipe, the portable plate of air draft non retern valve lightweight is opened toward vertical supervisor's direction; When indoor smokeless is discharged, portable plate is fallen by deadweight, is adjacent to fastener; During flue gas reverse back, form negative pressure in horizontal branch pipe, portable plate and fastener locking, prevent that the gas in air draft supervisor from can not enter indoor.
Advantage of the present utility model: simple structure, easy to make; Flexibility and reliability, air draft is smooth and easy; Sturdy and durable, service life is long; Highly versatile, with low cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing for an embodiment;
Fig. 1 is smoke discharging pipe three-way device main sectional view.
Fig. 2 is air draft non retern valve zoomed-in view.
The specific embodiment
As shown in Figure 1 and Figure 2, smoke discharging pipe three-way device adopts PVC material to make.Vertical supervisor 1 is provided with vertical deflector 3 with horizontal branch pipe 2 junctions, horizontal branch pipe 2 diameter 100mm, and its stage casing is provided with the air draft non retern valve 4 being in tilted layout, and air draft non retern valve 4 is by portable plate 5 and fastener 6 mix proportions.Air draft non retern valve 4 is arranged on horizontal branch pipe 2 stage casings, with 2 one-tenth 80 degree angles of horizontal branch pipe.Portable plate 5 is arranged on 1 one sides near vertical supervisor, and fastener 6 is arranged near an indoor side.The bottom margin of vertical deflector 3 is in vertical supervisor 1 and the following 25mm of horizontal branch pipe 2 node bottom margin.
As shown in Figure 2, portable plate 5 tops are connected with hinge 7 with fastener 6; Left and right, base and fastener 6 clampings.
