Steam noise and pressure reduction device with large pressure difference and low pressure reduction ratio

Abstract

The invention discloses a steam noise reduction and pressure reduction device with large pressure difference and low pressure reduction ratio. The steam noise reduction and pressure reduction device comprises a barrel, an inlet part, an outlet part and at least two sleeve type throttling orifice plates. The barrel is provided with a first end and a second end which are opposite. The inlet portion and the outlet portion are located at the first end and the second end, respectively. The sleeve type throttling orifice plate comprises a wall part and a bottom part, the radial section of the wall part is annular, and the bottom part is connected to one end of the wall part. A plurality of through holes are formed in the wall portion of each sleeve type throttling orifice plate, and the bottom of each sleeve type throttling orifice plate is far away from the inlet portion relative to the wall portion. And the at least two sleeve type throttling orifice plates are arranged in a step-by-step sleeving mode from inside to outside and are spaced, and the total area of the through holes is gradually increased from inside to outside, so that the respective pressure reduction ratios of the at least two sleeve type throttling orifice plates are gradually increased. According to the steam noise reduction and pressure reduction device with the large pressure difference and the low pressure reduction ratio, the purposes of pressure reduction and noise reduction can be achieved at the same time, noise pollution is reduced, and the equipment use environment is safer.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a steam noise reduction and pressure reduction device with large pressure difference and low pressure reduction ratio. Background technique [0002] Decompression equipment is widely used in pressure relief pipelines, temperature and pressure reduction devices and other equipment in shipbuilding, electric power, petrochemical and other industries. It can reduce the pressure of high-pressure steam so that the pressure parameters of the steam meet the production technical requirements. [0003] At present, the way of steam depressurization is generally to use throttling orifice or pressure reducing valve. If the pressure drop is large, multiple pressure reducing valves or throttling orifice will be used. However, if the pressure drop is too large, there will be many problems, such as the equipment is not compact enough, the volume is large, the cost will increase significantly...

Problems solved by technology

However, if the pressure drop is too large, there will be many problems, such as the equipment is not compact enough, the volume is large, the cost will increase greatly, and the most important thing is that the noise will exceed the standard.
