Abstract
The utility model relates to a hard polyvinyl chloride pipe material for water discharge, which is composed of an outer wall, a foaming core layer and an inner wall. The hard polyvinyl chloride pipe material for water discharge is characterized in that spiral bulges are distributed on the inner wall. The spiral bulges and the inner wall are connected into an integral body, and play a drainage function to the fluid in a pipe to cause the fluid to flow in a spiral state along the inner wall of the pipe, the vibration caused due to the impact of water current and gas is reduced, and thereby, noise is lowered. One proper included angle is formed from the spiral bulges and a pipe shaft core line, the flow state of the fluid in the pipe is similar to an eddy current phenomenon, and thereby, the speed of the water current is increased, and water discharge amount is augmented. The hard polyvinyl chloride pipe material for water discharge has the characteristics of light weight, convenient installation and low cost.
Description
The utility model relates to a kind of draining hard polyvinyl chloride pipe.
Existing draining has single material tubing and three-layer composite pipe material with hard polyvinyl chloride pipe, and is poor because of its soundproof effect when the smooth tube wall of water impact, brings certain worry for the people's life.Adopting increases wall thickness or changes the method that the mounting point reduces noise, and its effect is general, and has all improved cost, makes installation loaded down with trivial details.
The purpose of this utility model provides a kind of novel draining hard polyvinyl chloride pipe, need not raise the cost, and does not increase difficulty of construction and just can reduce noise.
The utility model draining with the technological scheme of hard polyvinyl chloride pipe is:
This draining hard polyvinyl chloride pipe is made up of outer wall, foamed core layer and three layers of tube wall of inwall, and it is characterized in that: inwall is furnished with the spirality projection.
The spirality projection of above-mentioned inwall is to link into an integrated entity with inwall.
Working procedure of the present utility model: the spirality projection of pipe material inner wall plays drainage to tube fluid, state is mobile in the shape of a spiral along inner tube wall to make it, middle form " air column " reduced current and gas collisions and the vibration that causes, thereby reduced noise.The spirality projection becomes a suitable angle with the pipe shaft axis, makes approximate " eddy current " phenomenon of flowing state of tube fluid.Thereby water velocity is increased, and increased water displacement.The foaming structure in tube wall middle level plays deadening, makes noise reduction more obvious.
The utility model has the advantages that: erasure effect is obvious; The water flowing resistance is little, and flow velocity increases, and water displacement increases, and the tubing light weight is easy for installation, with low cost.Be applicable to drainage system.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a longitudinal sectional drawing of the present utility model.
Fig. 2 is a transverse cross-sectional view of the present utility model.
As shown in the figure, this draining hard polyvinyl chloride pipe is made up of outer wall 1, foamed core layer 2 and 3 three layers of tube wall of inwall, and it is characterized in that: inwall is furnished with spirality projection 4.The spirality projection of inwall is to link into an integrated entity with inwall.The spiral protrusion of inwall becomes the angle about one 18 degree with the tubular axis center line.
Claims (2)
