Damper spring pneumatic butterfly valve - air conditioning pneumatic butterfly valve, air energy pneumatic butterfly valve
Damping spring pneumatic butterfly valve (also known as prestressed spring pneumatic butterfly valve) has the double advantages of low frequency and large damping of steel spring pneumatic butterfly valve, which eliminates the inherent resonance amplitude of steel spring in design.
Application in entertainment places: high-power subwoofer has a very powerful sound penetration, and traditional sound insulation materials can not handle such penetrating noise. Sound insulation damping felt combined with professional sound insulation technology can restore peace to the originally noisy room. Secondly, spring pneumatic butterfly valve is applied in industry: water pump room, air conditioning room, factory workshop.
The air compressor room and other places often have large noise. Being in this environment for a long time will lead to the reduction of human auditory characteristics, headache, coronary heart disease and other diseases. The damping spring shock absorber combined with professional sound insulation technology can suppress noise interference. The damping spring pneumatic butterfly valve has a wide load range and is convenient for users to choose.

Explanation on selection of rectangular fillet metal corrugated compensator:
1. After the user selects a suitable rectangular compensator according to the thermal displacement of the pipe system, at least the flow medium in the pipe, the design pressure of the flue gas duct, the maximum temperature during operation, the waveform (full height 216 mm, half height 108 mm) and wave number (single wave number of a single ripple does not exceed 6 waves) selected for the overall dimensions (length and width) of the cross section of the flue gas duct must be provided, So that we can stop the structural design and manufacturing of the compensator.
2. Maximum allowable shrinkage per wave recommended: full height △ α= ± 24mm half height △ α= ±12mm
3. Ash baffle: it can not be used for air duct or pipe with little dust, and it should be used for flue with much dust.
4. In order to reduce the number of corrugated sections of bellows, 50% cold drawing shall be considered.
5. The standard half height compensator is applicable to places with a sectional area of less than 4.6 square meters and the overall dimensions of the flue and air duct where one side is less than 1.5 m but more than 0.6 mm. Specification for tetrafluoro compensator Full height corrugated compensator is applicable to all flue ducts.
Compensator function: also known as expansion joint, contraction joint and corrugated compensator. The compensators are divided into several types: corrugated compensator, sleeve compensator, rotary compensator, square natural compensator, etc. Among them, corrugated compensator is more commonly used. The connection mode of rectangular corrugated compensator is divided into flange connection and welding to ensure the safe operation of the pipeline. The directly buried pipeline compensator is generally welded (except for trench devices).
It has the following functions:
1. Compensate the axial, transverse and angular thermal deformation of absorption pipe.
2. Expansion and contraction amount of corrugated compensator is convenient for installation and disassembly of valve pipeline.
3. Absorb equipment vibration, and reduce the impact of equipment vibration on pipeline.
4. Absorb the deformation of pipeline caused by earthquake and ground subsidence.
