Problems solved by technology
Since it is fixed welding, it is not conducive to replacement and the maintenance cost is high
In addition, if on the same sealing plate, more nozzles need to be designed, that is, to increase the distribution density of the nozzles, so that the gap between the nozzles is reduced, and the welding difficulty is increased. During the welding process, the gas outlet of the nozzles It is prone to deformation, the distribution of the air outlet nozzles of the overall nozzle is uneven, and the position accuracy is low

The invention discloses a structure for improving distribution density of jetting pipes. The structure comprises a sealing plate, the jetting pipes and a locating plate. The locating plate is installed under the lower surface of the sealing plate. Each jetting pipe is provided with an inlet and a jetting outlet. Installing through holes are formed in the sealing plate. Locating holes are formed in the locating plate. Sealing structures are arranged in the inner walls of the installing through holes; height locating grooves are formed in the outer walls of the jetting pipes. The jetting pipes are inserted from the installing through holes of the sealing plate and the locating holes of the locating pate and connected with the sealing structures in the installing through holes in a sealing mode. The sealing structures are buckled with the height locating grooves. Each sealing structure is provided with a connecting film having a deformation function and a sealing ring. A center hole is formed in each connecting film. The sealing rings are arranged at the edges of the inner sides of the center holes of the connecting films. The jetting pipes pass through the sealing rings, and the sealing rings are buckled inside the height locating grooves. More jetting pipes can be assembled under the same area, safety and stability of the structures are improved, and the maintenance cost is lowered.
Description
technical field [0001] The invention belongs to the technical field of sealing and processing of non-metallic small tubes, or the technical field of processing of non-metallic spray pipes, and specifically relates to a structure for increasing the distribution density of nozzles in the same area. Background technique [0002] A nozzle is a device used in various fields to guide the flow of gas. The traditional nozzle structure generally includes a sealing plate and a nozzle. The nozzle passes through the sealing plate. The installation method between the nozzle and the sealing plate is welded, and the nozzle is fixedly installed on the sealing plate through welding. Although this fixing method can ensure that the nozzle is firmly installed on the sealing plate, it also brings other problems. Because it is fixed welding, it is not conducive to replacement, and the maintenance cost is high. In addition, if on the same sealing plate, it is necessary to design more nozzles, th...
