Description

Low-resistance water separator-collector

Technical Field

The utility model relates to the technical field of fluid delivery and distribution, in particular to a low-resistance water separator-collector.

Background

The water separator-collector is a component in the fluid delivery system, and is used for distributing one water supply from the water supply main pipe to the multiple water supply branch pipes or collecting multiple return water from the return branch pipes to one return water main pipe.

Fig. 1 is a structure of a water diversion device commonly used in the prior art. The main body 1 is a circular tube, and the main pipe 2 and the branch pipe 4 are connected to the main body along the radial direction. When used as a water separator, water enters the body 1 from the manifold 2 and then flows out of the body 1 from the respective branch pipes 4. When acting as a water collector, water enters the body 1 from the various branch pipes 4 and then flows out of the body 1 from the manifold 2. The water inlet and outlet directions are 180 degrees, and the water flow direction is changed by 180 degrees without guidance in a narrow space, so that a very serious vortex is generated, and a very large flow resistance is formed.

The water separator-collector is one of main resistance components in the fluid delivery system, and the power consumption of the driving device is increased due to the fact that the resistance is too large, so that the power consumption of the fluid delivery system is further influenced.

(III) beneficial effects

In the prior art, in the water diversion device, the water flow direction is changed 180 degrees without being guided in a narrow space. In contrast, in the low-resistance water separator-collector provided by the utility model, the flow of water flow between the main port and the main body is guided or linearly guided by the main port section with the central axis being 90 DEG arc, and the flow of water flow between the main body and the sub-port is guided by the sub-port section with the central axis being 90 DEG arc. Therefore, the water flow is not easy to generate vortex in the flowing process, and can keep a good streamline shape, so that the flow resistance is small.

Further, the present utility model also provides a total orifice connecting section to further reduce flow resistance. If the pipe diameters of the main port section and the main port section are greatly different, when fluid enters the main port section from the main port section or enters the main port section from the main port section, certain vortex is generated, and certain flow resistance is caused. The total port connecting section can guide water flow between the total port section and the main body section, so that vortex is avoided, and resistance is reduced.

Further, in order to facilitate the discharge of the dirt from the low resistance water separator-collector, the utility model also provides a drain valve mounted on the main body section.

Example 1

As shown in fig. 2, the present embodiment provides a low resistance water separator-collector, comprising:

the main body section 1, the main body section 1 is a straight pipe with a circular cross section and equal diameters of all cross sections. Defining a straight line of the axis of the main body section 1 as an x coordinate axis, wherein the x coordinate of any point in space is an x coordinate value at the intersection point of a plane passing through the point and perpendicular to the x coordinate axis and the x coordinate axis;

the main mouth section 2, the main mouth section 2 is a section of pipeline with circular cross section and equal diameter of each section, the central axis of the main mouth section 2 is an arc with the angle equal to 90 degrees, the central axis of the main mouth section 2 and the central axis of the main body section 1 are on the same plane, the first end of the main mouth section 2 is connected with the end part of the main body section 1, the second end is connected with an external pipeline, and the positive direction of the x coordinate axis meets the following conditions: the x coordinate of the center of the first end of the total mouth section 2 is smaller than that of the center of the second end;

the split sections 4 are pipelines with circular cross sections and equal cross section diameters, the central axis of each split section 4 is a 90-degree circular arc, the number of the split sections 4 is n, n is more than or equal to 1, the central axis of each split section 4 is on the same plane with the central axis of the main body section 1, the first end of each split section 4 is connected to the side wall of the main body section 1, the second end of each split section 4 is connected with an external pipeline, the tangent line of the central axis of each split section 4 at the first end is parallel to the central axis of the main body section 1, and the x coordinate of the center of the first end of each split section 4 is larger than the x coordinate of the center of the second end;

the x-coordinate at the center of the first end of the total mouth section 2 is smaller than the x-coordinate at the center of the second end thereof, and the x-coordinate at the center of the first end of each of the divided mouth sections 4 is larger than the x-coordinate at the center of the second end thereof, which ensures that the fluid flow direction at the junction of the divided mouth section 4 with the main body section 1 and the fluid flow direction at the junction of the total mouth section 2 with the main body section 1 are the same, so that the fluid flow direction is unchanged between the divided mouth section 4 and the total mouth section 2. Considering that the central axis of the total port section is 90 degrees of arc, and the central axis of the split port section is 90 degrees of arc, when fluid flows in the low-resistance split water collector provided by the embodiment, each time the fluid changes in flowing direction, the fluid is guided by the pipeline with the central axis of 90 degrees of arc, vortex is not easy to generate, and the low-resistance split water collector has small flowing resistance.

The key to achieving reduced resistance in this embodiment is that each change in flow direction is directed through a conduit having a central axis that is an arc of an angle equal to 90, which may be achieved with the features described above in this embodiment, and other features are not required.

Further, in order to facilitate the discharge of the dirt in the low resistance water separator-collector, a drain valve 5 is mounted on the main body section 1.

Example 2

As shown in fig. 3, this embodiment provides another low resistance water separator-collector. Unlike embodiment 1, in this embodiment, the total mouth section 2 is a straight tube and the total mouth section 2 is parallel to the main body section 1. Thus, the flow direction is not changed when the fluid flows between the total mouth section 2 and the main body 1. Therefore, when the fluid flows in the low-resistance water separator-collector provided by the embodiment, the change of the flow direction is always guided through the pipeline with the central axis being the arc of 90 degrees, so that the low-resistance water separator-collector has small flow resistance.

Example 3

As shown in fig. 4, this embodiment provides yet another low resistance water separator-collector, which includes, in addition to the components of embodiment 1:

the main port connecting section 3 is a straight pipe with a circular section, two ends of the straight pipe are open, the main port connecting section 3 is positioned between the main body section 1 and the main port section 2, and the main body section 1 and the main port section 2 are connected.

When the pipe diameter of the main port section 2 and the pipe diameter of the main port section 1 are greatly different, certain vortex is generated when fluid enters the main port section 1 from the main port section 2 or enters the main port section 2 from the main port section 1, and certain resistance is caused. The main port connecting section 3 is arranged to guide the flow of water flow between the main port section 2 and the main body section 1, so that vortex flow is avoided, and the resistance of the low-resistance water separator-collector is further reduced.

Finally, it is noted that the above-mentioned embodiments are merely illustrative of the technical solution of the present utility model and not restrictive, and that other modifications and equivalents thereof by those skilled in the art are intended to be included in the scope of the claims without departing from the spirit and scope of the technical solution of the present utility model.
