Upper end, which is welded with the stable nut of coaxial line, the screw, is provided with set screw, and the set screw lower end, which is fixed with, to be connect
Ball is touched, the set screw of the screw lower end is provided with fixing nut.
It is preferred that, also including steam vent, multiple steam vents are uniformly provided with the supporting plate.
It is preferred that, fixed mount is support bar, and the support bar is uniformly provided with 3, described support bar one end and the body
End is welded and fixed, and the support bar other end is welded and fixed with the supporting plate lower end.
It is preferred that, the annular slab is integrally formed with the body, and the set screw lower end is fixed with contacting ball bonding.
It is preferred that, the annular slab is flange, and multiple installation screws are uniformly provided with thereon.
Specifically, by after the exhaust outlet connection of body and vavuum pump, vavuum pump is opened, then by changing set screw one
End in contact ball gos deep into the distance of exhaust outlet, produces the minimum position of noise until finding a vavuum pump, then uses fixing nut
Set screw is fixed.Further, the steam vent opened up in supporting plate, which is served, uniformly scatters the air of discharge, it is to avoid
Directly blow to supporting plate.
The beneficial effects of the utility model are：By setting the body being connected with vacuum pump discharges hole, and on body
There is provided interference air vibration produces the approach of noise, it is achieved thereby that noise reduction purpose.Silencing means structure of the present utility model
Simply, easily, manufacturing cost is relatively low, and has reached preferable erasure effect for operation principle.
