Said silencing means covers to blast pipe connect box opening part top.
Said silencing means is the external arc structure with air-inlet cavity, the place of connection, air-out chamber.
Said silencing means comprises noise reduction adiabator layer and zinc-plated orifice plate, and the arbitrary side or the two sides of zinc-plated orifice plate are provided with the noise reduction adiabator layer.
Said governor motion comprises baffle plate, adjusting rod, adjustment disk and handle; Handle is connected in the adjustment disk center; Adjustment disk is provided with the connecting rod that is on the adjustment disk diameter, and before and after adjusting rod is divided into two sections, the adjusting rod back segment is movably connected on non-central location on the connecting rod; Adjusting rod leading portion, blast pipe axial centre and adjustment disk center are on the same straight line, and the adjusting rod leading portion connects the corresponding setting with the blast pipe cross section of baffle plate.
Said discharge pipe is provided with air diffuser, and air diffuser is five face plate structures.
Said noise reduction adiabator layer is super glass wool layer or mineral wool layer or polyurethane foam layer.
The channel sized of said air intake passage is less than the discharge pipe caliber.
The noise reduction adiabator layer at said air-out cavity wall turning is arc structure.
After adopting above technical scheme, the beneficial effect that the utility model reaches is:
1, governor motion works the blast pipe intake size effect of regulating; Drive the adjustment disk rotation through regulating handle, drivening rod rotation synchronously, adjusting rod back segment and connecting rod are movably hinged; Connecting rod drive adjusting rod back segment moves along the line at adjusting rod leading portion and adjustment disk center; Thereby make the baffle plate that is connected in the adjusting rod leading portion be corresponding with the blast pipe cross section near or away from state, realize getting into the adjusting of air quantity size in the casing air-inlet cavity by blast pipe, easy to operate;
2, silencing means and cabinet wall noise reduction insulation material interlayer form streamlined air intake passage; By air-inlet cavity through streamlined air intake passage when blow in the air-out chamber; Air is compressed and expands, and resists the variation owing to noise sound wave effect causing air motion speed, and the noise reduction adiabator layer of silencing means and cabinet wall plays damping action; Sound wave causes the sound-absorbing material vibration in the noise reduction adiabator layer; Under sound-absorbing material friction and viscosity resistance effect, make a part of acoustic energy transform heat energy and be absorbed, thus the transmission of minimizing noise; Sound wave is through the zinc-plated orifice plate pore-throat and the hole wall friction of silencing means simultaneously; The loss of part acoustic energy is absorbed; The incident acoustic wave zinc-plated orifice plate of disturbance has hardly been avoided the air-swirl phenomenon in the process in air intake passage, transmitted of air-supply air-flow, reduces the air-swirl noise; Cooperating silencing means is the external arc structure with air-inlet cavity, the place of connection, air-out chamber, and the noise reduction adiabator layer at air-out cavity wall turning is arc structure, can further reduce the air-swirl noise, increases the air-supply fluency.
3, the ventilation terminal tank material can also can be aluminium zine plate material for galvanized sheet, and the antiseptic property of aluminium zine plate is that galvanized sheet gets 2 times, and corrosion resistance is strong, the service life of double extension ventilation terminal.
The utility model is set up silencing means and is formed streamlined air intake passage in the ventilation terminal casing; Satisfy the requirement of ventilation terminal air intake and air-out smoothness, low noise; It is simple in structure, compact, and excellent noise reduction effect is applicable to the end equipment of ventilating systems such as marine air conditioning, oil platform.
