How to reduce the noise of the electric pneumatic valve?

Electric pneumatic valve has become our usual work in the production of one of the most common type of pneumatic valve, the electric pneumatic valve a voice at work at ordinary times, how to reduce the noise of the electric pneumatic valve?

1。 Just using the silencer

muffler used in the control of pneumatic valve equipment directly, can reduce the noise of the pneumatic valve control. Electric pneumatic valve is mainly used to cut or connect line in the medium, can also be used on regulation and control of fluid, the 'V' pneumatic valve, hard seal the v-shaped core of carbide surfacing with strong shear force between metal pneumatic valve seat, especially suitable for fiber, micro solid material such as medium. Electric pneumatic valve belongs to electric pneumatic valves and electric adjusting a variety of pneumatic valve. Electric pneumatic valve connection methods mainly include: flange and clamp; Electric pneumatic valve seal form mainly has: rubber seal and metal seal. Electric pneumatic valve through the power signal to control the switch of pneumatic valve. However, when using muffler, often has some problems. First of all, if the silencer is useful, it requires a low flow. However, there is little practical value in low flow often make muffler, especially in the big traffic system. Sound elements and fluid medium are often not to cooperate. Third, the operating conditions may be very poor.

2。 Change the pipeline tag

increase the mother pipe wall thickness can reduce the noise of the pneumatic valve adjustment. However, once appear, noise, it will not lost mother along the tube length is sensitive, so usually need to mother in the whole pipe system using this method.

3。 Pipeline isolation method

this way, like a way to increase the wall thickness, can also be used to reduce the noise to declare. But, pay attention to three factors. Vertices, like change tube method, isolation method is also need to work on the entire system. Equipment materials carefully, in order to avoid material becomes' invalid ', thus seriously reduce the utility of this method. In the pipeline system, the general use of thermal insulation is limited in terms of noise reduction. Due to the suitable materials are not suitable for high temperature, using binder could melt, fundamentally changed its quality of acoustic and thermal properties.
