2. The utility model provides a pneumatic electromagnetic valve assembly with an adjustable valve opening and closing speed, which is characterized in that an electromagnetic valve, a first hole-shaped muffler and a second hole-shaped muffler are sequentially connected together in a threaded manner from top to bottom, so that the two hole-shaped mufflers can be screwed and combined. Because the two hole-shaped silencers have different apertures, the aperture of the silencer can be quickly switched through quick disassembly and assembly, the exhaust speed of the valve can be quickly adjusted, and the opening and closing speed of the valve can be adjusted according to the requirements of the production process.
3. The utility model can rapidly switch the muffler with different apertures according to the process requirement, so that the exhaust speed is moderate, the on-site production efficiency is not reduced due to the too slow opening and closing speed of the valve, the safety is ensured, and the process requirement is met.
