Abstract

The utility model mainly discloses a drain pipe cyclone which comprises a vertical pipe and a horizontal pipe, wherein the horizontal pipe is spirally jointed with the outer wall of the vertical pipe and is communicated with the vertical pipe; a flow guiding plate protruding upwards is arranged on the lower edge of the inner part of a connection part of the horizontal pipe and the vertical pipe. The waterflow in the horizontal pipe is close to the wall of the horizontal pipe and is smoothly drained donwards from the horizontal pipe, without being directly poured in the vertical pipe from the horizontal pipe, so that the nappe with the waterflow in the vertical pipe is eliminated, the air column effect of a single vertical pipe is stabler, and the drain is smoother.

Description

A kind of gutter cyclone

Technical field

The utility model relates to the construction drainage technical field, and is special relevant with a kind of single-stack drain system.

Background technology

Single standpipe is used very general in present highrise building, the drainage system of comparing tradition increase ventilating pipe has the saving architectural space, saves the gutter cost, easy construction, therefore the characteristics such as quiet become the high layer sewerage system of present main flow with the single standpipe of the special draining of cyclone.Existing cyclone much all adopts the mode of side spiral water inlet, when lateral inflow, when laterally flowing water pours standpipe, the impact dynamics is larger, can form larger overflow with standpipe direction current, destroy the intermediate air post, and the sound that the flowing water impact is sent is larger.Therefore in the design of eddy flow stream device, the place of connecting is improved to the adherent spiral of side pipe and imports, and current are through the helical structure of side pipe, form the convolution shape, changed water (flow) direction, can slow down thus the overflow that produces with the standpipe current, the assurance inner air tube is unobstructed, reduces simultaneously noise.

But the lateral inflow of this helicoidal structure, its side pipe and straight tube junction, wall communicates within it, and side pipe is equivalent to the spiral cell body that is provided with on the standpipe inwall, when current reach certain speed and certain flow, just can be fitted in convolution whereabouts water inlet in the spiral cell body.In case current are less, when the impact dynamics is inadequate, current are not enough to form convolution and fall in the spiral cell body, but directly flow into the standpipe from the junction, although therefore the impact dynamics is little under the weep state, but the current noise is fairly obvious, and the inventor designs a kind of gutter cyclone thus, and this case produces thus.

The utility model content

Main purpose of the present utility model provides a kind of gutter cyclone, eliminates the noise that weep produces when being used for side spiral water inlet.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

A kind of gutter cyclone comprises standpipe and transverse tube, and transverse tube spiral applying standing tube outer wall is communicated with standpipe, has the flow deflector to upper process in inner lower edge, the junction of transverse tube and standpipe.

Described flow deflector is to arrange along the transverse tube spiral.

Described flow deflector is for reducing highly successively from top to down.

The starting altitude of described flow deflector is 2～3cm.

After adopting such scheme, the utlity model has many beneficial effects:

In the utility model therein transverse tube inwall lower edge bossed flow deflector is set, therefore, when weep is laterally intake, although flow velocity is little, but by the guiding of flow deflector, can be smoothly with current adherent drainage and descending from the transverse tube of spiral, and can directly not pour into to standpipe from transverse tube, thereby eliminated the noise of current, further slowed down the pressure that the standpipe draining is born.

Fig. 2 be among Fig. 1 A to schematic diagram;

Fig. 3 is the schematic cross-section one of the utility model preferred embodiment;

Fig. 4 is the schematic cross-section two of the utility model preferred embodiment.

The specific embodiment

By reference to the accompanying drawings, preferred embodiment is described in further details to the utility model.

A kind of gutter cyclone, the parts that relate generally to comprise standpipe 1 and transverse tube 2, and standpipe 1 is the hollow body that is communicated with up and down, is connected with transverse tube 2 at its sidewall.

Transverse tube 2 applying standpipe walls, 1/4 spiral that coils its body circumference connects.Inner lower edge has the flow deflector 3 to upper process in the junction of transverse tube 2 and standpipe 1.Flow deflector 3 is along transverse tube 2 junction spirals and lower the setting, and, from original position, reduce highly successively from top to down at the height of flow deflector 3, be traditionally arranged to be 2～3cm at starting altitude, this highly neither affects drainage speed, also can guarantee the guiding of current.

When the utility model uses, the up and down two ends of standpipe 1 are connected on the vertical pipeline of drainage system, transverse tube 2 connects on the horizontal pipeline of drainage system, when the current in the horizontal pipeline are incorporated into standpipe 1 by transverse tube 2, circle round successively and descend along the spiral caliber of transverse tube 2 in inside, current are subject to stopping of flow deflector 3 simultaneously, prevent from directly being circulated in the standpipe 1 from transverse tube 2, guarantee the adherent convolution of current, further abate the noise.

Above-described embodiment only is used for explaining inventive concept of the present utility model, but not to the restriction of the utility model rights protection, allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should fall into protection domain of the present utility model.
