Problems solved by technology

Although this design method can meet the requirements of low-pressure steam users, it complicates the configuration and operation of the auxiliary steam system and increases the size of the system.
At the same time, since each branch is equipped with only one regulating valve, one stop valve and one safety valve, there is no backup of equipment, which reduces the reliability of the system

Embodiment Construction

[0012] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, in the traditional decompression device, a stop valve and a safety valve are respectively installed on each branch connecting the main steam main pipe and the low-pressure user, that is, the decompression device on the working steam branch of the low-pressure user is set independently. Although this design method can meet the requirements of low-pressure steam users, it complicates and increases the size of the auxiliary steam system. At the same time, since each branch is equipped with only one regulating valve and one safety valve, there is no equipment backup, which reduces the reliability of the system.

[0014] The new automatic decompression device provided by the present invention is a centralized decompression valve group, including a decompression pipeline a...

Abstract

The invention provides a novel nuclear-powered ship high-pressure steam automatic decompression device and method. The novel nuclear-powered ship high-pressure steam automatic decompression device comprises a decompression pipeline and a gas transmission pipeline, the input end of the decompression pipeline communicates with a steam master pipe, the output end of the decompression pipeline communicates with the gas transmission pipeline, the decompression pipeline is composed of two decompression branch pipes in parallel, a gas transmission pipe comprises a gas transmission main pipe and a plurality of gas transmission branch pipes, and the gas transmission branch pipes communicate with the gas transmission main pipe. The novel nuclear-powered ship high-pressure steam automatic decompression device and method can realize centralized decompression of high pressure steam, and after decompression, the high pressure steam can be transported to low pressure steam users such as a main air extractor.

Description

technical field [0001] The invention belongs to the technical field of a secondary circuit auxiliary steam system, and in particular relates to a new type of nuclear power ship high-pressure steam automatic decompression device and method. Background technique [0002] In marine nuclear power plants, the function of the auxiliary steam system is to transport the high-pressure steam in the steam main pipe to the steam turbine generator set, steam turbine auxiliary equipment, and low-pressure steam generator, and to transport the high-pressure steam to the main extraction after decompression device, steam seal extractor and auxiliary extractor of steam generator set. The high-pressure steam automatic decompression device is an important equipment of the auxiliary steam system. The decompression function of the device reduces the auxiliary steam pressure to the pressure required by the main extractor and other low-pressure steam users. Therefore, this device is of great signif...
