On, the pneumatic cavity and the adjusting valve chest are fixedly connected in the power that on support frame as described above body, the pneumatic cavity is generated
It acts in the universal driving shaft and valve block shaft and the valve block is driven to rotate in turn, with the opening size of control valve and adjusting
Air quantity.
Further, the gasket seal of sealing lubrication effect has been equipped between the efflux nozzle and spout card slot.
Further, fire proof seal quieter material is equipped on the inner wall of the adjusting valve chest.
Further, the connecting flange connecting with air supply duct is provided on the outside of the adjusting valve chest.
Further, the surface of the adjusting valve chest is coated with fire resistant coating.
Air circulation jet device is adjusted using vibration damping and noise-reducing structure with low noise in painting workshop of the present invention, passes through
Pure air, hot wind or dry wind are introduced workshop by blower, spray air to the spraying operation hilllock in workshop by efflux nozzle
Position region.
Compared with prior art, the beneficial effects of the present invention are:
(1) the air circulation jet apparatus structure compact and reasonable, volume-diminished occupy less space；
(2) spout card slot and the changeover portion for adjusting valve chest effectively reduce air-flow using streamline curved design
Local resistance reduces generated vibration and noise when air-supply, has achieved the effect that reducing noise and drag；
(3) inside of efflux nozzle uses tapered gradual-enlargement type curved surface, effectively increases air supply velocity；
(4) power that pneumatic cavity generates acts on universal driving shaft and valve block shaft and rotates with moving valve plate, so as to adjust
Air output；
(5) efflux nozzle can be made to adjust within the scope of 30 ° in spout card slot, to change wind direction, so as to adjust
Save air supply direction；
(6) spout card slot uses connecting flange and connecting hole to connect with valve chest is adjusted, and operation easy to disassemble has maintenance
Convenient advantage；
(7) it is provided with gasket seal between efflux nozzle and spout card slot, plays the role of sealing lubrication.
In short, the present invention is exclusively used in the air-supply of painting workshop, using the structure of reducing noise and drag, and inside is close equipped with preventing fires
Seal quieter material, can either fire proof seal, also effectively reduce the vibration generated when air-supply and noise, meet workshop to air-supply
The requirement of amount and noise control.
