Abstract
The invention discloses a rainproof cap for a pipeline, comprising an exhaust pipe end and an evacuation outlet end. The rainproof cap for the pipeline is characterized by also comprising a shell, a ponding disk, a drain pipe and a connection post, wherein the exhaust pipe end is connected with the evacuation outlet end by the shell; the pipe diameter of the shell is more than that of the exhaust pipe end; the shell is internally provided with the ponding disk of which the calibre is more than the pipe diameter of the evacuation outlet end; and the lower part of the ponding disk is provided with the drain pipe. With the structure provided by the invention, the rainproof cap has benefits of realizing the rainproof function via simple structure, and simultaneously, the rainproof cap of the invention is more durable and safer than a traditional rainproof cap.
Description
Technical field
The present invention relates to the pipeline rainhat, relate in particular to the silencing apparatus rainhat.
Background technique
Silencing apparatus is to stop sound transmission and a kind of device of allowing air communication to cross, is the important measures of eliminating air power noise.Silencing apparatus is mounted on the air-flow path of aerodynamic force equipment (as blower, air compressor) or the device of the reduction noise in the inlet and exhaust system.Silencing apparatus can stop the propagation of sound wave, allows the air communication mistake, is the effective tool of control noise.
Rainhat is mainly used on the silencing apparatus, divides boiler steam discharge silencing apparatus rainhat, blower fan silencing apparatus rainhat, and boiler steam discharge silencing apparatus rainhat manufactured materials is generally stainless steel and aluminum alloy, and the blower fan silencing apparatus is generally used carbon steel.Rainhat of the prior art is mainly hat-shaped, is arranged on the emptying outlet end.But its shortcoming is obvious, runs into severse weathers such as typhoon, and rainhat drops easily, and working life is shorter.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of pipeline rainhat, and it can overcome above-mentioned shortcoming, and simple in structure.
For solving the problems of the technologies described above, the invention provides following technological scheme: a kind of pipeline rainhat, comprise exhaust duct end, emptying outlet end, wherein: also comprise shell, ponding dish, drain pipe, attachment post, wherein the exhaust duct end is connected with the emptying outlet end by shell, and the caliber of described shell is greater than the exhaust duct end, and described enclosure is provided with the ponding dish, the bore of described ponding dish is greater than the caliber of exhaust outlet end, and described ponding dish bottom is provided with drain pipe.
As the preferred version of a kind of pipeline rainhat of the present invention, wherein: described ponding dish is connected on the inwall of shell by attachment post.
As the preferred version of a kind of pipeline rainhat of the present invention, wherein: the bore of described ponding dish is greater than exhaust duct.
As the preferred version of a kind of pipeline rainhat of the present invention, wherein: described shell is provided with guide plate near the circumferencial direction of emptying outlet end one side, and the caliber of described guide plate is less than the bore of ponding dish.
As the preferred version of a kind of pipeline rainhat of the present invention, wherein: the gas flow area between described ponding dish and the shell is greater than the sectional area of exhaust duct.
The beneficial effect that adopts structure of the present invention is for to have realized rainproof effect by simple structure, simultaneously than the more durable safety of traditional rainhat.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 is the schematic representation of pipeline rainhat of the present invention.
Embodiment
As shown in the figure, comprise among the figure: exhaust duct 1, shell 2, emptying outlet end 3, ponding dish 4, guide plate 5, attachment post 6, drain pipe 7.
Among the figure, exhaust duct 1 is connected with shell 2, and shell 2 diameters are greater than exhaust duct 1, and shell 2 can be welded for two end sockets up and down.Be provided with ponding dish 4 in the described shell 2, the bore of ponding dish 4 is greater than the caliber of emptying outlet end 3.Ponding dish 4 is connected with shell 2 inwalls by attachment post 6, and ponding dish 4 bottoms are provided with drain pipe 7
Gas flow area between described ponding dish 4 and shell 2 inwalls is greater than the sectional area of exhaust duct 1.Described shell 2 is provided with guide plate 5 near the circumferencial direction of a side of emptying outlet end.The caliber of described guide plate 5 is less than the bore of ponding dish 4.
It should be noted that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
