branch pipe structure

Abstract

A manifold structure includes a manifold and multiple outlet flow control units. The manifold includes an inlet and multiple outlets. Each outlet is provided with a connector, which has a connecting end, an exposed end, and a channel. The connecting end is located at the outlet and has a flow inlet, while the exposed end has a flow outlet. The channel connects the flow inlet and the flow outlet. The outlet flow control unit is located within the channel and includes a valve core and a resilient element. The valve core is located within the channel, and the resilient element is fitted onto the valve core. The different pressure differences generated by the distance between the inlet and each outlet cause each resilient element to move and deform relative to the outlet along the axial direction of the channel, thereby compressing the resilient element and changing the spacing between the resilient elements. This allows adjustment of the flow rate at each outlet to achieve uniform flow.

Claims

1. A manifold structure comprising: a manifold including an inlet and a plurality of outlets, wherein each of the outlets is provided with a connector having a connecting end, an exposed end, and a channel formed between the connecting end and the exposed end, the connecting end being disposed at the outlet and having a flow inlet for communicating with the outlet, the exposed end having a flow outlet, and the channel communicating with the flow inlet and the flow outlet; and a plurality of outlet flow control units disposed within the channel of each of the connectors, each outlet flow control unit comprising: a valve core disposed within the channel; and an elastic element movably disposed within the channel and adapted to be sleeved on the valve core, wherein the elastic element can be moved and deformed relative to the flow outlet along the axial direction of the channel according to the pressure difference generated by the distance between the inlet and the outlet of the manifold, thereby compressing the elastic element and changing the spacing of the elastic elements, thus adjusting the flow rate of the outlet.

2. The manifold structure as claimed in claim 1, wherein the plurality of elastic elements of the outlet flow control units comprise different spring weights.

3. The manifold structure as claimed in claim 1, wherein the plurality of elastic elements of the outlet flow control units are selected with different spring weights depending on the location of the outlet flow control units at the outlets.

4. The manifold structure as claimed in claim 1, wherein the plurality of elastic elements of the outlet flow control units are selected with different spring weights based on the pressure difference generated by the distance between the inlet and the outlet of the manifold.

5. The manifold structure as claimed in claim 1, wherein the spring rate of the elastic element disposed at the front outlet, which is closer to the inlet, and the spring rate of the elastic element disposed at the rear outlet, which is farther from the inlet, is less than the spring rate of the elastic element disposed at the rear outlet.

6. The branch pipe structure as claimed in claim 1, wherein the exposed end has an end wall having the outlet, and a first end of one of the elastic elements is close to or abuts against the inside of the end wall.

7. The manifold structure as claimed in claim 6, wherein a stop portion is provided in the channel, the stop portion being adjacent to the connecting end, a second end of one of the elastic elements being close to or abutting the stop portion, and the elastic element being positioned between the end wall and the stop portion.

8. The manifold structure as claimed in claim 6, wherein the outer diameter of the first end of the elastic element is greater than the diameter of the outlet and / or the inner diameter of the first end of the elastic element is smaller than the diameter of the outlet.

9. The manifold structure as claimed in claim 6, wherein the inner diameter of the first end of the elastic element is less than or equal to the outer diameter of the valve core.

10. The manifold structure as claimed in claim 1, wherein the cross-sectional area of ​​the valve core is smaller than the cross-sectional area of ​​the outlet.

11. The manifold structure as claimed in claim 1, wherein each outlet has a different pressure differential depending on its distance from the inlet, which can compress and change the spacing of the elastic elements in each outlet, thereby adjusting the flow rate of the outlet so that the flow rate of each outlet is approximately the same, so as to achieve uniform flow distribution.
