The utility model relates to ventilation system for buildings, specifically is a kind of manual regulating device of the volume damper for regulating air volume.
Background technique
The ventilation duct of constructure ventilation system is provided with volume damper, volume damper comprises valve body and the controlling device that is fixed on the valve body, be provided with a valve block in the ventilation duct in the valve body, controlling device is fixed with a main shaft, main shaft and valve block are fixed, controlling device is with the moving valve plate rotation by rotating spindle, thereby regulate the size of air output, during such as the transverse cross-section parallel of valve block and ventilation duct, valve block blocks ventilation duct, and air output is minimum, when the cross section of valve block and ventilation duct is vertical, valve block is opened maximum with ventilation duct, and air output is maximum.
Most of volume damper mounting point is higher in the building, and usage comparison is frequent, this part volume damper need to adopt electric adjusting device to regulate, and the mounting point of another part volume damper is not high, be installed in the place of convenient operation, if this part volume damper still adopts complex structure, manufacture cost height, uses the electric adjusting device that needs power consumption, and is then economical very poor.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of simple in structure, low cost of manufacture, energy-conserving and environment-protective to need not the manual regulating device of the volume damper of power consumption.
Technical solution of the present utility model is, a kind of manual regulating device of volume damper is provided, it comprises main shaft and the pedestal fixing with valve block, it also comprises spanner, stop sleeve, main screw and nut, pedestal is provided with main shaft circular hole and fan annular distance, and the center of circle of fan annular distance overlaps with the center of circle of main shaft circular hole, and main shaft passes the main shaft circular hole of pedestal and the front portion of spanner is fixed, the spanner middle part is provided with the screw via hole, and main screw passes successively fan annular distance, stop sleeve, screw via hole and nut and screws.
The working principle of this controlling device is: unscrew nut, head and the nut of winner's screw are no longer pushed against spanner, stop sleeve and pedestal, can catch spanner rear end this moment, very easily along the fan annular distance main screw that slides, impel spanner to rotate around the center of circle of main shaft circular hole, and then so that with the anterior fixing main shaft of spanner along with spanner rotates, finally be with moving valve plate to rotate, realize the adjusting of valve body air quantity; The deflection angle of valve block reaches customer requirements, after namely the aperture of volume damper, air output meet the demands, nut is screwed, pedestal, stop sleeve, spanner between winner's screw head and the nut are killed mutually, spanner is locked can't to rotate, like this, the aperture of volume damper, air output have also just immobilized.
Adopt above structure volume damper manual regulating device compared with prior art, have the following advantages:
The manual regulating device of this volume damper is simple in structure, low cost of manufacture, energy-conserving and environment-protective need not power consumption, is particularly useful for that the volume damper setting height(from bottom) is not high, the occasion of mounting point convenient operation, and is economical good.
As improvement, pedestal is made of top board and two L-type plates, and the riser top of each L-type plate and an end of top board are fixed, the transverse slat of each L-type plate and the valve body of volume damper are spirally connected, and fan annular distance and main shaft circular hole all are located on the top board, and such is simple in structure, easy to assembly, stable and reliable for performance.
As also improving, the spanner front end is provided with sleeve pipe, the tube wall of sleeve pipe is penetrated with radial screw bore, be provided with radial screw in the radial screw bore, the diameter of main shaft is less than the bore of sleeve pipe, and collar bush is combined in the sleeve pipe and radial screw pushes against main shaft such structure, the process that main shaft and spanner is fixing is simple and convenient, and two parts are solid and reliable after fixing.
As improving again, be provided with pad between nut and the spanner, can prevent from like this damaging spanner by pressure after nut from screwing.
