Embodiment

[0012] like figure 1 As shown, the integrated deaerator nozzle structure diagram provided by the present invention includes a body 16, and the bottom of the spring shaft 15 is successively pierced with chassis 1, 5 water separators (i.e. the first water separator 4, the second Divider tray 5, third diverter tray 6, fourth diverter tray 7 and fifth diverter tray 8. The five diverter trays form six layers of nozzles, and the spray angles of each nozzle from top to bottom are: 170° . 3. Each layer of water distribution pan is supported by a group of small springs, so that the opening of each layer under pressure is uniform.

[0013] The remaining part of the spring shaft 15 and the supporting sleeve 9 are arranged in the body 16 , and the part of the spring shaft 15 located in the body 16 is covered with a large spring 12 . The large spring 12 makes each layer of the water distribution plate pressed together, and maintains a certain pre-tightening force, so that the spout is o...

Abstract

The invention relates to an integral deaerator nozzle, which comprises a body. The integral deaerator nozzle is characterized in that a chasis, at least a diverting disc and a bearing sleeve are arranged on the bottom part of a spring shaft in sequence in a penetrating way, a guide shaft penetrates through the chasis, the diverting disc and the bearing sleeve, a small spring is sheathed outside the guide shaft, the rest part of the spring shaft and the bearing sleeve are arranged in the body, and a large spring is sheathed outside the part of the spring shaft in the body. The invention has the advantages that the integral structure is simple and easy to mount, demount and maintain. When pressure water enters into the inner cavity of the nozzle, the pressure is directly applied on the tensile force generated on the chasis, so that the large spring is compressed, the water nozzle is opened, thus completely satisfying the requirement.

Description

technical field [0001] The invention relates to a nozzle for an integrated deaerator. Background technique [0002] The integrated deaerator mainly consists of spray deaeration section, deep deaeration section and water storage. After the condensed water enters the upper water chamber of the shell, it passes through the large flow nozzle, and under the action of the pressure difference, the condensed water is sprayed out in the form of a conical film and enters the spray deaeration section. In this section of space, water is in full contact with steam for spray deoxygenation, and most of the non-condensable gas is removed in this section, and is discharged to the atmosphere through the exhaust pipe. [0003] But at present there is no nozzle for a deaerator that is easy to assemble and can meet the requirements. Contents of the invention [0004] The purpose of the present invention is to provide a nozzle that is easy to assemble and can meet the requirements. [0005] ...
