Silencer for safety valve for chemical plant

Abstract

The invention discloses a silencer for a safety valve for a chemical plant. The silencer comprises a silencer barrel, a partition plate, through holes, an upper end socket, a lifting lug, a support, a base, a lower end socket and an air inlet. The two ends of the silencer barrel are provided with the upper end socket and the lower end socket. The lifting lug is arranged on the upper end socket. The through holes are evenly formed in the outer wall of the silencer barrel. The support is arranged at the portion, close to the lower end, of the outer side of the silencer barrel. The air inlet is arranged in the lower end of the lower end socket. The silencer for the safety valve for the chemical plant has the beneficial effects that the structure is simple, compact and reasonable, assembling is convenient and rapid, and connection is reliable; the purpose of silencing is achieved by disturbing airflow and sound waves of the silencer, and noise is lowered; internal intake and exhaust are smooth, power losses are small, and the silencing effect is good; the working reliability of the silencer is greatly improved, and use and application are easy; an exhaust pipe will not bear large external force due to the fact that the silencer is placed, disassembling and overhauling are convenient, and displacement, taking-off and returning of the safety valve are not affected.

Description

technical field [0001] The invention relates to the field of mufflers, in particular to a muffler for a safety valve used in a chemical plant. Background technique [0002] The safety valve muffler for chemical plants is a kind of muffler, which is mainly used for the effective muffler of high-temperature and high-pressure steam discharge from safety valves, PCV valves and exhaust valves in industries such as electric power, chemical industry, and metallurgy. For boiler safety doors and exhaust valves, it is It can be seen as an integral part of the pipeline. After the internal acoustic treatment, the generation and transmission of noise can be weakened, so that the noise reduction of the outlet noise can reach 20∽30 decibels (A sound level), and the corresponding loudness is reduced by more than 50%. Subjective I feel that the effect is obvious. The muffler is a device for reducing the noise of the airflow. It is installed in the pipeline or on the intake and exhaust ports,...

AI Technical Summary

Problems solved by technology

Due to the complex structure, heavy weight, high-temperature oxidized sound-absorbing filler, high-speed airflow impacting the sound-absorbing filler, water vapor permeating the sound-absorbing filler, etc., the muffler is prone to frequent maintenance, poor noise reduction effect, and short service life. , the muffler effect is relatively poor, the intake and exhaust resistance is relatively large, and the air fluidity is poor, which greatly reduces the reliability of the muffler.
