Description

Air-conditioning air-supply distributor box

Technical field

The utility model relates to a kind of urban rail transit vehicles parts, specifically, relates to a kind of air-conditioning air-supply distributor box.

Background technology

Subway maintenance engineering inspection vehicle is owing to the particularity of its function, and supply air system has following characteristics:

1, many, the air-conditioning of roof apparatus arrangement can not be arranged between two parties, causes both sides air supplying distance, air-supply air quantity all inequality;

2, the air-supply zone is many, respectively has separate space of one's own, and there is barometric gradient in each zone, and uniform distribution and air-conditioning return air difficulty cause blowing.

For above-mentioned reasons, subway maintenance engineering inspection vehicle supply air system requires high to the reasonable distribution of air-supply air quantity, all inequality again with the supply air system of locomotive and city rail vehicle, therefore need to propose a kind of simple in structure, be easy to regulate the air-conditioning air-supply distributor box that air quantity distributes.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of said structure, provides a kind of simple in structure, practical, is easy to regulate the air-conditioning air-supply distributor box that air quantity distributes.

For achieving the above object, the technical scheme that the utility model adopted is: comprising: casing and the thin air damper in casing and thick air damper, and it is characterized in that: described thick air damper places the position such as the formula of casing:

$L1=L2*\frac{Q1}{Q1+Q2}$ Wherein: the thick air damper of L1-position

L2-distributor box inlet length

Q1-left end air channel air quantity

Q2-right-hand member air channel air quantity;

Described thin air damper is made of three thin air damper deflectors of arc and places distributor box casing inlet, and first thin air damper deflector is positioned at directly over the thick air damper, and first to the 3rd interval L is 10-20cm.

Compared with prior art, the beneficial effect that the utility model had is: can adapt to multiple duct air-conditioning supply air system, the air-supply air quantity of regulating the air-conditioning unit easily distributes, and the air output in each supply air duct is met design requirement, thereby effectively reaches the purpose of balanced ventilation.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1, thin air damper, 2, thick air damper, 3, casing, 4, regulating handle.

The specific embodiment

The utility model comprises casing 3 and thin air damper in casing 31 and thick air damper 2.At first according to the design proportion of each air channel air output, thick air damper 1 places the fixed-site of casing 3 constant, as formula:

$L1=L2*\frac{Q1}{Q1+Q2}$ Wherein: the thick air damper of L1-position

L2-distributor box inlet length (identical) with air-conditioning air outlet length

Q1-left end air channel air quantity

Q2-right-hand member air channel air quantity;

L2, Q1, Q2 are known parameters in the formula, the position of hence one can see that thick air damper 2.

Thick air damper 2 is made of thick air damper deflector, and its radius is determined by following formula

$H1=\frac{2}{3}H0$

H1---thick air damper deflector radius

H0---air channel height is the Known designs parameter, can get H1 thus.

Thin air damper 1 is made of three thin air damper deflectors of arc and places distributor box casing 3 inlets, and wherein first thin air damper deflector is positioned at directly over the thick air damper 2, and first, second, third interval L is 15cm.

Thin air damper deflector arc radius and the thick identical H1 that is of air damper deflector radius, its thin air damper deflector arc length increases successively, is respectively

, H2, wherein H2 is casing 3 air inlet height, is determined by installation dimension, also can reference

Provide definite.In the debug phase, thin air damper deflector arc end part is established regulating handle 4, is convenient to regulate the deflector angle, can after having debugged.

In concrete the enforcement, tentatively regulate by 2 pairs of air-flows of thick air damper earlier, regulate the angle of deflector in the thin air damper again by the regulating handle 4 of thin air damper 1, air-flow is finely tuned, after meeting the demands that each thin air damper deflector welding is fixing, produce in batches.

Claims (1)

1. air-conditioning air-supply distributor box comprises: casing (3) and the thin air damper (1) casing (3) in and air damper (2) slightly, and it is characterized in that: described thick air damper (2) places the position such as the formula of casing (3):

$L1=L2*\frac{Q1}{Q1+Q2}$ Wherein: the thick air damper of L1-position

L2-distributor box inlet length

Q1-left end air channel air quantity

Q2-right-hand member air channel air quantity;

Described thin air damper (1) is made of three thin air damper deflectors of arc and places casing (3) to enter the mouth, first thin air damper deflector is positioned at directly over the thick air damper (2), and first, second interval L to the 3rd thin air damper deflector is 10-20cm.
