Abstract
A screw hush pipe with a hollow wall is composed of a pipe wall (1) and a plurality of continual helical protuberances along the inner surface of the pipe wall (1), and is characterized in that a plurality of hollow holes perforating at the upper and the lower ends of the pipe wall (1) are arranged between the inner surface and the outer surface of the pipe wall (1). Compared with the prior art, the utility model has the remarkable advantages of obvious noise damping effect, reasonable structure, convenient installation and easy popularization, and in particular to be suitable for the high-rise building.
Description
Technical field
The utility model relates to a kind of flow of liquid siphunculus, especially relates to a kind of flow of liquid siphunculus of empty wall spiral.
Background technique
A kind of novel hush pipe of Xiao Shouing takes tube inner wall to be provided with some helical projections in the market, makes when liquid passes through in pipe, and along the helical projection and in the shape of a spiral shape falls.The flow of liquid siphunculus of this structure because liquid is to fall twist, is formed centrally a gas column in pipe in pipe, have certain sound deadening, but to cause sound deadening be not clearly because of its liquid directly acts on tube wall.
Technological scheme
The utility model is in order to overcome deficiency of the prior art, provide a kind of sound deadening more significant flow of liquid siphunculus, adopted following technical conceive: even sealing close tube wall forms body by one, be provided with several at the internal surface of described tube wall and be the spiral projection in borderland, it is characterized in that between the outer surface of described inner surface of tube wall and tube wall, being provided with several and lead in the tube wall hollow hole at two ends up and down along inner surface of tube wall.
Because the utility model is provided with several along the continuous spiral projection of inner surface of tube wall at the internal surface of tube wall, and between the inside and outside surface of tube wall, be provided with several and run through the up and down hollow hole at two ends of tube wall, liquid is by tube wall the time, under the double action of helical projection and hollow hole, sound deadening is obvious, is desirable environment-friendly products.
Description of drawings
Fig. 1 is a cross-sectional configuration schematic representation of the present utility model.
Fig. 2 is the vertical cut-away view of part of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, tube wall 1 by continuous sealing is formed body, internal surface at described tube wall 1 is provided with several along the continuous spiral projection 2 of inner surface of tube wall, and is provided with the hollow hole 3 that several run through tube wall two ends about in the of 1 between the outer surface of the internal surface of described tube wall and tube wall 1.
Claims (1)
1, a kind of empty wall helical silencing pipe, formed along the projection [2] that tube wall [1] internal surface is the continuous helical shape by tube wall [1] and several, it is characterized in that between the internal surface and outer surface of described tube wall [1], be provided with the hollow hole [3] that several run through tube wall [1] upper/lower terminal.
