Abstract

The utility model discloses a pipeline fluid mixer, which comprises a high-pressure fluid inlet, at least one low-pressure fluid inlet, a diminishing pipe, an inhalation chamber and an outflow opening, wherein the high-pressure fluid inlet connects with the larger opening of the diminishing pipe; the low-pressure fluid inlet connects with the inhalation chamber and opens therein; the inhalation chamber connects with the outflow opening; the diminishing pipe passes through the inhalation chamber and the smaller opening thereof is arranged where the inhalation chamber and the outflow opening connect. A high-pressure fluid, when passing through the diminishing pipe, can produce a negative pressure in the reverse direction, i.e. at the inhalation chamber; under the effect of the negative pressure, the low-pressure fluid is helped to flow into the inhalation chamber, so the fluids can be mixed uniformly and steadily.

Description

A kind of pipeline fluid blender

Technical field

The utility model relates to a kind of blender, particularly a kind of pipeline fluid blender.

Background technology

In producing and living; run into the situation that two or more pipeline fluid need mix mutually at the interface of pipeline through regular meeting; but it is because all different from flow, flow velocity, pressure between the different fluid of different pipelines; so under influence each other; be easy to cause mixing inhomogeneous; flow velocity, instability of flow, even might the less inflow pipe line clogging of build-up of pressure under the influence of the bigger inflow pipe of pressure, the big grade of changes in flow rate be unfavorable for the situation of mixing.

The innovation and creation content

The purpose of this utility model provides a kind of two or more pipeline fluid that makes and mix the pipeline fluid blender of flow velocity, stability of flow when the interface of pipeline mixes.

For achieving the above object, the utility model is taked technical scheme: a kind of pipeline fluid blender, and it comprises high-pressure fluid inlet, at least one low-pressure fluid inlet, reducing pipe, suction chamber and flow export; Described high-pressure fluid inlet is connected for big mouthful with described reducing pipe; Described low-pressure fluid inlet is connected with described suction chamber, is opened in the suction chamber; Described suction chamber is connected with described flow export; Described reducing pipe passes described suction chamber, and the reducing pipe osculum is positioned at the junction of described suction chamber and flow export.

Described reducing pipe is preferably steel pipe.

The utility model is owing to be provided with reducing pipe in the high-pressure fluid porch, make high-pressure fluid flow velocity when flowing out reducing pipe strengthen suddenly, just produce a bigger negative pressure in the suction chamber in direction with the fluid flowing opposite, under the effect of negative pressure, low-pressure fluid flows in the suction chamber by the low-pressure fluid inlet at an easy rate, and then and high-pressure fluid mixes and flow out from flow export, mix very even, stable, will never have influence on the outflow of low-pressure fluid, but promote the outflow of low-pressure fluid by the negative pressure that high-pressure fluid produces.

The specific embodiment

As shown in Figure 1, the utility model pipeline fluid blender, by high-pressure fluid inlet 1, one low-pressure fluid inlet 2, steel reducing pipe 3, suction chamber 4 and flow export 5 are formed; High-pressure fluid inlet 1 is connected for 3 big mouthfuls with reducing pipe; Low-pressure fluid inlet 2 is connected with suction chamber 4, is opened in the suction chamber 4, and suction chamber 4 is connected with flow export 5; Reducing pipe 3 passes suction chamber 4, and its osculum is positioned at the junction of suction chamber 4 and flow export 5.

During use, high-pressure fluid pipes is connected on the high-pressure fluid inlet, and the low-pressure fluid pipeline is connected on the low-pressure fluid inlet, and flow export is connected with mixed discharge tube.

In the above-described embodiments, the low-pressure fluid inlet also can be a plurality of, can determine according to actual conditions, promptly utilizes device of the present utility model to carry out the mixing of multiple liquid.

Claims

1, a kind of pipeline fluid blender is characterized in that: it comprises high-pressure fluid inlet, at least one low-pressure fluid inlet, reducing pipe, suction chamber and flow export; Described high-pressure fluid inlet is connected for big mouthful with described reducing pipe; Described low-pressure fluid inlet is connected with described suction chamber, is opened in the suction chamber; Described suction chamber is connected with described flow export; Described reducing pipe passes described suction chamber, and the reducing pipe osculum is positioned at the junction of described suction chamber and flow export.
