Abstract

The invention provides a sound-absorbing velocity-flow spiral drainage pipe. The drainage pipe adopts a spiral structure, and the inner wall is regularly arranged with triangles with different heights and semicircular raised spiral ribs. The fluid in the riser falls through the taper of the water collector and the function of the diverter ribs, which increases the displacement. Increase the wall resistance of the pipe to the water flow, so that the water flow can be forced to flow along the pipe wall in a water film shape, reducing the impact on the pipe wall. Due to the special structure of the spiral pipe, the water flow velocity is reduced and the water flow is reduced. Tongue resistance coefficient keeps the central air core in the riser up and down, stabilizes the pressure fluctuation in the standpipe, effectively reduces the most common negative pressure suction and positive pressure splash in the drainage riser, and greatly improves the water flow capacity Great enhancement, and greatly reduced water flow noise.

Description

A sound-absorbing velocity-flow spiral drain pipe

technical field

The invention relates to the field of drainage pipes, more specifically, to a sound-absorbing velocity-flow spiral drainage pipe.

Background technique

The inner wall of the existing drainage pipe is relatively smooth, and the water flow is not easy to form a water film to flow along the pipe wall, and hit the pipe wall in a chaotic state in the pipe; and it cannot effectively prevent the transmission of noise, which brings "uneasy" factors to users' lives.

Contents of the invention

The invention provides a sound-absorbing speed-flow spiral drainage pipe, which can effectively reduce water flow noise

In order to achieve the above-mentioned technical effect, the technical scheme of the present invention is as follows:

A sound-absorbing velocity-flow spiral drainage pipe, first and second raised ribs are evenly distributed on the inner wall circumference of the drain pipe, and the first raised ribs and the second raised ribs are arranged at intervals ; The first raised rib and the second raised rib extend spirally on the inner wall of the drain pipe.

Preferably, the first raised ribs are triangular raised ribs.

Further, the triangular raised ribs are extruded with the inner wall of the drain pipe at one time, and form an included angle with the axis of the drain pipe, in a triangular shape.

Further, the angle between the triangular protruding ribs protruding from the inner wall of the drain pipe is not greater than 70°.

Preferably, the second raised rib is a raised arc in the shape of a semicircle.

Further, the second raised rib and the inner wall of the drain pipe are extruded at one time.

Compared with the prior art, the beneficial effects of the technical solution of the present invention are:

The invention adopts a spiral structure, and the inner wall has regularly arranged triangles with different heights and semicircular raised spiral ribs. Its unique structure makes the fluid of the horizontal branch pipe flow in along the tangent and the fluid of the standpipe pass through the taper of the water collector to gather and divert. The role of the ribs falls, increasing the drainage. The wall resistance of the pipe to the water flow is increased, so that the water flow can be forced to flow along the pipe wall in the form of a water film, reducing the impact on the pipe wall. Due to the special structure of the spiral pipe, the water flow speed is reduced and the water flow rate is reduced. Tongue resistance coefficient keeps the central air core in the standpipe up and down, stabilizes the pressure fluctuation in the standpipe, effectively reduces the most common negative pressure suction and positive pressure splash in the drainage standpipe, and greatly improves the water flow capacity Great enhancement, and greatly reduced water flow noise.

In order to better illustrate this embodiment, some parts in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product;

For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings.

The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Example 1

As shown in Figure 1-2, a sound-absorbing velocity-flow spiral drainage pipe has first raised ribs 4 and second raised ribs 3 evenly distributed on the circumference of the inner wall 2 of the drain pipe, and the first raised ribs The ribs 4 and the second protruding ribs 3 are arranged at intervals; the first protruding ribs 4 and the second protruding ribs 3 extend spirally on the inner wall 2 of the drain pipe.

The first protruding rib 4 is a triangular protruding rib. The triangular protruding rib is extruded together with the inner wall 2 of the drain pipe, and forms an included angle with the axis of the drain pipe, in a triangular shape.

As shown in FIG. 3 , the included angle of the triangular raised ribs protruding from the inner wall of the drain pipe is no greater than 70°.

The second protruding rib 3 is a protruding circular arc in the shape of a semi-circular arc, and the second protruding rib 3 and the inner wall 2 of the drain pipe are extruded at one time.

The drainage pipe adopts a spiral structure, and the inner wall 2 has regularly arranged triangles with different heights and semicircular raised spiral ribs. Its unique structure makes the fluid of the horizontal branch flow into the taper along the tangent and the fluid of the standpipe through the water collector. The effect of gathering and diverting ribs is reduced, increasing the drainage. Increase the wall resistance of the pipe to the water flow, so that the water flow can be forced to flow along the pipe wall in a water film shape, reducing the impact on the pipe wall. Due to the special structure of the spiral pipe, the water flow velocity is reduced and the water flow is reduced. Tongue resistance coefficient keeps the central air core in the riser up and down, stabilizes the pressure fluctuation in the standpipe, effectively reduces the most common negative pressure suction and positive pressure splash in the drainage riser, and greatly improves the water flow capacity Great enhancement, and greatly reduced water flow noise.
