Abstract

The utility model discloses an equal-pressure distributor, which comprises a body. A liquid-distributing chamber is arranged in the body. The liquid-distributing chamber is provided with a fluid inlet. The liquid-distributing chamber is divided into a transition zone and an equal-pressure zone. The cross-sectional area decreases from the junction of the transition zone and the equal pressure zone, and the wall of the equal pressure zone is provided with several fluid outlets. In the utility model, by changing the cross-sectional area of the equal-pressure zone in the liquid separation chamber, the cross-sectional area of the equal-pressure zone is reduced from the junction of the transition zone and the equal-pressure zone so that the equal-pressure zone is equal-pressured, so the shunt pipe is The different depths of the fluid outlet inserted into the equal pressure zone will not affect the uniformity of the split flow, so that the pressure of the media flow is equal and the split flow flows out evenly; in addition, the utility model has a simple structure, low manufacturing cost, and is easy to popularize.

Description

an equal pressure distributor

technical field

The utility model belongs to the field of fluids, in particular to an equal-pressure distributor for splitting flow of heat exchangers in equipment such as air conditioners and water treatment, and belongs to the improvement technology of the equal-pressure distributor.

Background technique

Fluid distribution is a problem often involved in the fluid field. In air conditioners, water treatment and other equipment, fluid distributors are often used. At present, there are two common distributors in the domestic market: ordinary distributors (as shown in Figure 1) and Limited distributor (shown in Figure 2).

The processing technology of ordinary distributor is relatively simple, and the processing cost is low, but because the liquid distribution chamber 2 is not equal pressure, the uniformity of the distribution will be affected by the different insertion depth of the distribution pipe 5 (as shown in Figure 3) . Although the limit type distributor improves the uniformity of liquid separation, its processing technology is complicated, consumes more materials, and the cost is much higher than that of ordinary type distributors. In addition, the number of distribution distribution holes in a certain cross-section is relatively limited.

Contents of the invention

The purpose of the utility model is to overcome the above problems and provide an equal pressure distributor with uniform pressure, uniform flow distribution, simple structure and low manufacturing cost.

In order to achieve the above purpose, the technical solution of the utility model: an equal pressure distributor, including a body, a liquid separation chamber is provided in the body, a fluid inlet is provided in the liquid separation chamber, and the liquid separation chamber is divided into a transition zone and a Pressure zone, the cross-sectional area of the constant pressure zone decreases from the junction of the transition zone and the constant pressure zone, and the chamber wall of the constant pressure zone is provided with a number of fluid outlets.

The cross-sectional shape of the equal pressure zone is circular.

The cross-sectional shape of the equal pressure zone is a regular polygon.

A filter screen is provided between the transition zone and the equal pressure zone.

Further, the above-mentioned fluid outlet is arranged on the cavity wall at the bottom of the equal pressure zone.

In the utility model, by changing the cross-sectional area of the equal-pressure zone in the liquid separation chamber, the cross-sectional area of the equal-pressure zone is reduced from the junction of the transition zone and the equal-pressure zone so that the pressure in the equal-pressure zone is equal, so the shunt pipe is from The different depths of the fluid outlet inserted into the equal pressure zone will not affect the uniformity of the distribution, so that the pressure of the medium flow is equal and the flow of the distribution flows out evenly; in addition, the utility model has a simple structure, low manufacturing cost, and is easy to popularize.

Detailed ways

Example

The structure of the isobaric distributor of the present utility model is shown in accompanying drawing 1, comprises device body 1, and device body 1 is provided with liquid separation chamber 2, and liquid separation chamber 2 is provided with fluid inlet 3, and described liquid separation chamber 2 is divided into The transition area 21 and the equal pressure area 22 , the cross-sectional area of the equal pressure area 22 decreases from the junction of the transition area 21 and the equal pressure area 22 , and several fluid outlets 4 are provided on the chamber wall of the equal pressure area 22 .

In this embodiment, in order to simplify the manufacturing process, the cross-sectional shape of the equal pressure zone 22 is a circle, and of course it can also be a regular polygon. The fluid outlet 4 is arranged on the cavity wall at the bottom of the equal pressure zone 22, and the shunt pipe (not shown) is inserted on the fluid outlet 4. The arrow in the accompanying drawing 1 indicates the inflow direction of the media flow.

In order to prevent the diverted media stream from containing impurities and blocking the diversion pipe, a filter is provided between the transition zone 21 and the equal pressure zone 22 .

When the utility model is used, the medium flow enters the transition zone 21 from the fluid inlet 3, enters the equal pressure zone 22 after being filtered, and then flows out from each shunt pipe, and the medium flow enters the equal pressure zone 22 at a certain pressure, The pressure near the transition zone 21 will be higher than the pressure away from the transition zone 21, but because the cross-sectional area of the equal pressure zone 22 near the transition zone 21 is smaller than the cross-sectional area of the equal pressure zone 22 far away from the transition zone 21 , when the media flow flows from a large section to a small section in the equal pressure zone 22, the pressure will increase, and the increased pressure just supplements the pressure lost during the flow of the media flow, so that the pressure of the media flow in the entire equal pressure zone 22 is Equal, so the depth of the shunt pipe inserted from the fluid outlet 4 into the equal pressure zone 22 will not affect the uniformity of the shunt flow, so that the pressure of the medium flow is equal and the shunt flow flows out evenly.
