Description

Pipe section with rectifying function

Technical Field

Background

Large-caliber pipe sections are often used in industry for transporting liquid, and the flow of the liquid needs to be measured in the transportation process to obtain the transportation quantity of the liquid.

Detailed Description

The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.

As shown in fig. 1 to 6, a pipe section having a rectifying function according to an embodiment of the present utility model is used for liquid transportation. The pipe section with the rectifying function comprises a main pipe section 1 and a plurality of rectifying sheets 2. A cavity 12 for the liquid to circulate is formed in the pipe wall 11 of the main pipe section 1. A plurality of rectifying vanes 2 are provided at one end of the cavity 12 into which the liquid enters in the direction of the liquid flow. Wherein, the commutating sheets 2 are horizontally arranged in the cavity 12 along the radial direction of the main pipe section 1, and a plurality of commutating sheets 2 are arranged in parallel. The flow sheets 2 are arranged in parallel, so that the flow velocity of the liquid is the most uniform to the greatest extent, and the plurality of rectifying sheets 2 are arranged at one end of the cavity 12 where the liquid enters, so that the liquid can be layered, the flow velocity of the liquid is relatively uniform and stable, and the accuracy of flow measurement is improved.

If the plurality of rectifying sheets 2 are not arranged in parallel, more turbulence occurs after the liquid circulates between the rectifying sheets 2, and thus the rectifying effect is not achieved. As shown in fig. 5 and 6, before the rectifying fin 2 is not arranged, the middle of the water flow is protruded relatively to two sides, and the uneven flow is larger, so that the measurement of the flow is easy to deviate. After the commutator segments 2 are arranged in the cavity 12, the water flow is divided, and the area with uneven flow is relatively reduced, so that the measurement accuracy is improved.

In one embodiment, as shown in fig. 3, the rectifying sheet 2 is provided with two sheets. Too many or too few fairings 2 are not desirable. When the number of the rectifying sheets 2 is too large, the flow rate of the liquid is reduced, so that the transportation capacity of the cavity 11 is reduced, and the manufacturing cost and difficulty of the main pipe section 1 are increased. Too little of the rectifying sheet 2 is provided, and the rectifying effect is not achieved, so that the accuracy of flow measurement cannot be improved. To further improve the accuracy of the flow measurement, the thickness of the fairing 2 is between 0.8mm and 1.2 mm. The thickness of the rectifying sheet 2 is also not too thick or too thin, and too thick results in poor rectifying effect and more uneven flow of liquid throughout the cavity 12. If the rectifying sheet 2 is too thin, the rectifying effect cannot be achieved, which increases the manufacturing cost of the main pipe section 1.

Since the commutator segments 2 are in the liquid for a long time, and part of the liquid may be corrosive. Therefore, the commutator segment 2 is required to be made of a material having a certain corrosion resistance and being less prone to rust. In one embodiment, the fairing 2 is a stainless steel fairing 2. The stainless steel rectifying sheet 2 has good corrosion resistance and is not easy to rust. In addition, the stainless steel fairing 2 is relatively inexpensive, which reduces the manufacturing costs of the main pipe section 1.

In one embodiment, as shown in fig. 1 and 2, in order to facilitate the installation of a transducer for measuring flow, two sides of the main pipe section 1 are symmetrically provided with a plurality of transducer sockets 3 for inserting the transducer, and the transducer sockets are communicated with the cavity 12. The symmetrical arrangement of the transducer sockets 3 allows for a better fit between the transducers, thereby making the flow rate measurement more accurate. In addition, the transducer socket 3 is obliquely arranged with the pipe wall 11 of the main pipe section 1, and the included angle between the transducer socket 3 and the pipe wall 11 of the main pipe section 1 is 50-60 degrees, so that the transducer can accurately measure. Specifically, two transducer sockets 3 are respectively arranged on two sides of the main pipe section 1. Four transducer sockets 3 are provided on the main spool piece 1 in total, and four transducers can be inserted. The transducers are matched with each other for use, and each two transducers form a group. When one of the groups has a problem, the other group can still be used normally, so that the normal measurement of the flow rate is ensured. The two groups of transducers can work simultaneously, so that the average value of data measured by the two groups of transducers is taken, and the measurement accuracy is improved.

In one embodiment, as shown in fig. 2 and 4, the main pipe section 1 is provided with flange pieces 4 at both ends. The flange 4 is provided with a plurality of fixing holes 41. The flange plate 4 and the fixing hole 41 may be used for connection between pipe sections. The pipe section with the rectifying function can be additionally arranged on any pipe section according to the actual use condition, so that the installation of a pipeline and equipment with the pipe section with the rectifying function is convenient.

Compared with the prior art, the pipe section with the rectifying function is provided with the plurality of rectifying sheets 2 in the cavity 12, so that the liquid in an unstable flow state can be regulated to the liquid in a stable flow state. And the multiple rectifying sheets 2 are arranged in parallel, so that the rectifying effect of the multiple rectifying sheets 2 can be effectively improved. In addition, the rectifier sheet 2 is a stainless steel rectifier sheet 2, has certain corrosion resistance and rust resistance, and ensures the rectification effect of the rectifier sheet 2 after long-time use.
