Description

Variable flow swirler

Technical Field

The utility model relates to a pipeline field is variable flow swirler particularly.

Background

In a drainage pipeline system of a building, a core accessory of a single-riser system is a swirler. The cyclone plays a crucial role in the drainage capacity of the system. The size of the drainage capability directly influences the noise reduction effect of the drainage system and the safety of water seal. Once the water seal is damaged, bacteria and odor can enter a living room, and noise and bacteria directly harm the health of people. The cyclone has the function of realizing water vapor shunting, and the most key technology of the cyclone is the design of the shape, the number and the angle of the cyclone blades except the integral shape of the cyclone.

The traditional swirler is integrally molded, and the shape is fixed. The building is divided into a plurality of layers, small high-rise buildings, high-rise buildings and super high-rise buildings, and for the buildings with different heights, the drainage capacity of the vertical pipe needs to be selected to be different levels, but at present, the drainage capacity cannot be achieved at all, and one brand can provide the drainage effect. The most significant reason is the manufacturing cost of the cyclone, an expensive die development expense.

In addition, because traditional swirler all is whole when moulding plastics that the swirler need be changed because of damaging or other reasons, need change whole swirler down, the cost is higher, also causes the wasting of resources simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model aims at reducing swirler development cost, use cost for swirler's change is more convenient, reduces the wasting of resources.

The utility model discloses a concrete technical scheme as follows:

a variable flow swirler comprises a shell and an inner core, wherein the upper part of the shell is a through pipe, the side surface of the upper through pipe part can be provided with a side through pipe, the lower part of the upper through pipe part is a hollow cone, and the lower end of the hollow cone is a through hole; the outer wall of the inner core is separably attached to the inner wall of the lower portion of the outer shell, and guide vanes are arranged on the inner wall of the inner core. Because the binding face of inner core and shell is the toper, wide from top to bottom narrow, under the effect of gravity, rivers pressure, inner core and shell closely laminate, and can not take place relative slip. Therefore, the shell of the swirler is separated from the guide vane inside the swirler, and replacement is facilitated.

Further, the number, shape, angle and the like of the guide vanes can be set according to the requirement, and 1, 3 or 6 guide vanes can be set. All the various guide vanes that exist among the prior art can all pass through the technical scheme of the utility model make it and shell phase separation, then laminate work each other.

Furthermore, the outer wall of the inner core and the inner wall of the outer shell are both flat surfaces, which is beneficial to the tight fit of the inner core and the outer shell.

Furthermore, the upper part of the through pipe is provided with an upper joint, and the lower end of the hollow cone is provided with a lower joint used for being jointed with other pipe fittings.

Furthermore, the width of the guide vanes is increased from top to bottom and then reduced, the guide vanes are spirally downward along the inner wall of the inner core, and the rotating directions of all the guide vanes are the same.

Has the advantages that: the utility model discloses with the shell of swirler and inside guide vane phase separation, be convenient for change, adapt to the needs of different situation, reduce swirler development cost, use cost for the change of swirler is more convenient, reduces the wasting of resources.

The device comprises a shell 1, a through pipe 11, a hollow cone 12, a side through pipe 13, an upper joint 2, a lower joint 3, an inner core 4 and guide vanes 41.

Detailed Description

As shown in fig. 1-3, a through pipe 11 is arranged at the upper part of a housing 1 of the variable flow swirler, a side through pipe 13 is arranged at the side surface of the upper through pipe 11 and used for communicating other branches, a hollow cone 12 is arranged at the lower part, the lower end of the hollow cone 12 is a through hole, an upper joint 2 is arranged at the upper part of the through pipe 11, and a lower joint 3 is arranged at the lower end of the hollow cone 13.

The variable flow swirler 1 has an inner core 4 inside it, which is configured as shown in fig. 5. The outer wall of the inner core 4 and the inner wall of the hollow cone 12 of the outer shell are separably attached to each other, and 3 guide vanes 41 are arranged on the inner wall of the inner core 4. The width of the guide vane 41 is increased from top to bottom and then decreased, the guide vane 41 spirals downward along the inner wall of the inner core 4, and the rotation directions of all the guide vanes 41 are the same. The outer wall of the inner core 4 and the inner wall of the hollow cone 12 of the outer shell are both flat surfaces and are tightly attached. Fig. 4 is a cross-sectional view of the inner core of the embodiment in which 3 guide vanes 41 are provided on the inner wall in order to clearly show the spiral direction of the guide vanes 41.

According to the actual situation, the inner core 4 with only 1 guide vane 41 or the inner core 4 with 6 guide vanes 41 is replaced. All the various guide vanes that exist among the prior art can all pass through the technical scheme of the utility model make it and shell phase separation, then laminate work each other. Because the binding face of inner core 4 and shell 1 is the toper, wide from top to bottom narrow, under the effect of gravity, rivers pressure, inner core 4 and shell 1 closely laminate, and can not take place relative slip. Therefore, the outer casing 1 of the cyclone is separated from the guide vane 41 inside, and the replacement is convenient.

The above disclosure is only for the preferred embodiment of the present invention, but not intended to limit itself, and any changes and modifications made by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
