              I: Safety valve muffler application and product characteristics:

              Safety valve muffler is mainly used for the effective silencing of high temperature and high pressure steam emissions from safety valves, PCV valves and exhaust valves in power, chemical and metallurgical industries. The exhaust noise of safety valve is mainly medium and high frequency noise, and the muffler can not affect the start and return of safety valve at the same time. So the muffler of safety valve adopts the muffler principle of through-hole injection combined with resistance. Among them, through-hole expansion is used instead of small-hole injection, which ensures the smooth exhaust of safety valve in structure. The structure of sound blocking piece has a good absorption of medium and high frequency noise.

              Exhaust muffler of safety valve has the following advantages:
              1. The muffler can meet the requirement of "Hygienic Standards for Noise in Industrial Enterprises", and reduce the noise of outlet by 25-30 decibels (A upgrade);
              2. The muffler does not affect the discharge flow of the safety valve at the same time, so that the safety valve can start and return to its seat smoothly.
              3. The structure and performance of muffler can adapt to high temperature, high pressure, the capability of each emission frequency band and the diameter of exhaust pipe.

               II. Principle of safety valve muffler

              The new type of safety door muffler manufactured by our factory adopts the principle of through-hole injection and resistance, in which the large-hole expansion and flow control are used to instead of the micro-hole perforated plate type. First, that the exhaust of the safety door is smooth in structure must be ensured. The multi-layer perforated sound absorption is combined with the principle of resistance silencing, so that the steam sound wave enters the innumerable small holes of the porous sound absorption material, excites the molecular vibration of the porous material in order to overcome frictional resistance and viscous force and become heat energy, that is to say, the ideal silencing effect is achieved, and the smooth removal of steam is ensured.
               III. Installation notes for safety valve muffler
              (1) The muffler shall be installed vertically on the top of the furnace. As shown in the drawing, the muffler holder shall be fixed to the top of the furnace with a section steel bracket.
              (2) In order to increase the wind resistance of the top of the furnace, the muffler body is supported or an expansion elbow is installed in the exhaust pipe in front of the muffler to absorb heat expansion.
              (3) The drainage outlet at the lower part of the muffler should be connected to the ditch smoothly, and the valve should not be installed.
              (4) The muffler is installed on the top platform of the furnace, and a rainproof cover of thin plates shall be made.
              (5) There should be no drainage point on the exhaust pipe between the safety valve or exhaust valve and the muffler.
              (6) For small-hole mufflers, there should be no impurities in the exhaust pipe before installation, so as to prevent small-hole blockage. For example, the newly installed boiler should flush the exhaust pipe to remove impurities in the pipe.
              (7) For safety doors, in principle, only one muffler is installed for a safety door.
              The muffler of boiler safety valve exhaust is mainly used in power plant, chemical industry, iron and steel industry for effective noise reduction of safety valve and exhaust valve steam emission. Generally the exhaust muffler can be classified into the drum safety valve, the exhaust muffler of the superheater safety valve and the exhaust muffler of the reheater safety valve are used.

              Safety valve exhaust mufflers are carefully designed in accordance with users' emission medium and requirements. Therefore, the following information should be provided when ordering mufflers:
              (1) Exhaust steam volume of safety valve (T/h), pressure and temperature.
              (2) Exhaust pipe diameter and wall thickness;

              IV. Safety Valve Muffler

              Low pressure steam muffler (TD type)

              Variety industrial and mining enterprises use a large number of low-pressure boilers with a capacity of 0.13Mpa or less. There are also a large number of low-pressure thermodynamic devices in the thermal system of power plants, such as back-pressure steam turbine, deaerator, auxiliary extractor, oil pump of steam turbine, boiler continuous sewage discharge, regular sewage discharge, etc. The exhaust pipe of the above equipment requires a muffler with light structure and more convenient for installation. The company has designed special mufflers for different requirements, which can meet the requirements of users.
              Steam exhaust silencer -Direct deal-Price concession, Golden quality
              For the safety door of boiler and other devices, the exhaust steam should not only avoid excessive noise, but also let the steam flow discharge smoothly. For this reason, the usual muffling means of multi-stage throttling and orifice injection are not suitable. This limitation was the difficulty for design the safety door muffler, and also the reason for the muffling difference of the safety door muffler. The muffler of the new model safety door also adopts the principle of anti-noise, spraying and resistance, in which the larger hole expanding replaces the smaller diameter flow control hole, which strengthens the effect of anti-noise, spraying and anti-noise in structure, and achieves the ideal effect of noise elimination.
              Variety industrial and mining enterprises use a large number of low-pressure boilers with a capacity of 0.13Mpa or less. There are also a large number of low-pressure thermodynamic devices in the thermal system of power plants, such as back-pressure steam turbine, deaerator, auxiliary extractor, oil pump of steam turbine, boiler continuous sewage discharge, regular sewage discharge, etc. The exhaust pipe of the above equipment requires a muffler with light structure and more convenient for installation. The company has designed special mufflers for different requirements, which can meet the requirements of users.

              After the steam boilers and related thermal equipment pipelines are installed and maintained, the impurities in the pipelines should be cleaned up with steam, and a lot of noise will be generated during the cleaning process. TC muffler adopts a three-stage muffler structure. It also effectively muffles noise through the principle of anti-noise, spraying and resistance. It effectively integrates the TB and TA design in the internal structure.
