Spray head for steel pipe paint spraying

Abstract

The invention discloses a spray head for steel pipe paint spraying. The spray head comprises an upper semi-annular pipe and a lower semi-annular pipe, the two ends of the upper semi-annular pipe and the two ends of the lower semi-annular pipe are open and provided with connecting flanges, and the connecting flanges of the upper semi-annular pipe and the connecting flanges of the lower semi-annularpipe are fixedly connected through bolts. A plurality of paint spraying openings are formed in the inner side of the upper semi-annular pipe and the inner side of the lower semi-annular pipe, and a paint inlet communicated with the interior of the upper semi-annular pipe is formed in the upper semi-annular pipe. The spray head is of a structure consisting of the upper semi-annular pipe and the lower semi-annular pipe, can be directly arranged on the outer side of a steel pipe in a sleeving mode, is very convenient to use, and is high in paint spraying efficiency; The upper semi-annular pipe and the lower semi-annular pipe are connected through the connecting flanges, a sealing groove and a sealing ring are arranged, the sealing performance is good, and internal paint is not prone to leaking out.

Description

technical field [0001] The invention relates to a spray head for painting steel pipes. Background technique [0002] Generally, steel pipe is a widely used steel structure. During the production process of steel pipe, it is often necessary to spray paint on the steel pipe to prevent corrosion of the steel pipe. [0003] When spraying steel pipes, it is necessary to place the steel pipes in the air, and then spray paint on the steel pipes. When spraying paints, in order to improve the painting efficiency, an annular spray head is often used to cover the outside of the steel pipe for painting. However, the conventional annular spray head needs to be sprayed from the steel pipe. It is very inconvenient to use because it is inserted on both sides. Contents of the invention [0004] In view of the above problems, the present invention provides a nozzle for painting steel pipes, which effectively solves the problems pointed out in the background technology. [0005] The techni...
