Description

Technical Field

[0001] The utility model relates to the technical field of pipe connectors, in particular to an alloy wear-resistant sootblowing reducer. Background Art

[0002] A sootblowing reducer is a special pipe fitting used in the industrial field. It is used to connect two pipes of different diameters. It is mainly used in sootblowing systems to connect pipes of different diameters to achieve smooth flow and transmission of gas or fluid. During the sootblowing process, it plays the role of changing the pipe diameter, adjusting the flow rate and pressure.

[0003] When regulating the air flow through a reducer, the airflow usually carries various particulate matter, such as dust and sand. When the high-speed airflow passes through the surface of an object, these particles will collide and rub against the object. Moreover, due to the different diameters inside the reducer, the wear degree of the small-diameter inner wall will increase, reducing the service life of the reducer. For this reason, we have proposed an alloy wear-resistant sootblowing reducer. Utility Model Content

[0009] Further preferably, four fixed blocks are fixedly connected to the outside of the buffer rack and the four fixed blocks are distributed in a circular array.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the utility model, when the high-speed airflow is transmitted, the buffer frame can move downward with the connecting ring through the elastic force of the spring, so that the card slot can be connected with the sealing ring to protect the inner wall of the reducer. At the same time, the high-speed airflow can move to the interior of the buffer frame through the guide groove opened by the connecting ring for transmission, thereby reducing the impact of the airflow on the inside of the pipeline, reducing the wear of the inner wall of the reducer, and improving the service life of the reducer.

[0012] In the utility model, when the device is used, the flow rate of the airflow can be adjusted and transmitted through the installed reducer body. When the flow rate of the airflow is small, the elastic force of the spring can push the buffer frame through the fixed block to reset the airflow, so that the airflow can be transmitted normally from the inside of the reducer body, thereby ensuring the transmission of the airflow flow.

The outer side of the connecting block 4 is slidably connected with the interior of the limit block 3. A support assembly 5 is provided inside the reducer body 1 to protect the interior of the reducer body 1. When the buffer rack 201 moves, through the sliding connection between the limit block 3 and the connecting block 4, the sliding connection between the connecting rod 601 and the through hole 502, and the sliding connection between the limit groove 503 and the limit block 2 504, the buffer rack 201 can be limited to prevent the buffer rack 201 from being offset.

[0024] In this embodiment, Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the support assembly 5 includes four support frames 501, which are fixedly connected to the inside of the reducer body 1 and are distributed in a ring array.

The connecting rod 601 is slidably connected to the bottom of the through hole 502. The bottom of the connecting rod 601 passes through the through hole 502 and is fixedly connected to the top of the limiting block 2 504.

The spring 602 is contracted by the elastic force of the spring 602, so that the fixed block 603 can move downward with the buffer frame 201 through the connecting rod 601, so that the buffer frame 201 can move downward with the connecting ring 205, so that the slot 203 can be connected with the sealing ring 204.
