The GRAVITY CONTROL valve plate for saving weight is closed, and when the intracorporal negative pressure of valve increases, inside and outside differential pressure overcomes the gravity for adjusting weight, thus
Valve plate is driven to open the benefit wind realized to system, and the opening degree of the utility model valve plate and the size of negative pressure are positively correlated,
The degree of regulation of valve body is substantially increased, the utility model has the advantages of simple structure, and does not need control electronic component, greatly improves
The reliability of equipment, while can also be greatly expanded by the unlatching wind pressure value of the mobile position control valve plate for adjusting weight
Its scope of application.
2, it is provided with rolling bearing between the valve body and shaft of the utility model, on the one hand reduces shaft rotation abrasion, prolongs
The service life of long equipment, while guaranteeing the connection precision of shaft；On the other hand the frictional resistance of shaft is reduced, to guarantee to turn
Axis can rotate under the conditions of defined wind pressure, and then guarantee the reliability of degree of regulation and equipment.
3, it is abound with adjusting screw thread on the adjusting screw rod of the utility model, adjusts and is additionally provided with stop nut on rear side of weight, side
Just according to the starting wind pressure of needs of production flexible modulation valve plate, the scope of application of air-valve has been widened significantly, while passing through limit
Position nut avoids weight position from changing, and guarantees the reliability and degree of regulation of equipment.
4, the air inlet of the utility model is provided with air inlet short tube, and the outlet end for entering the wind short tube is sealed by valve plate, by into
Wind short tube extend into the installation site of the intracorporal length adjustment valve plate of valve, is conveniently adjusted the position of associated components, improves equipment
Reliability, while improving the leakproofness of valve plate.
5, it is additionally provided with filter screen on the air inlet short tube of the utility model, prevents extraneous sundries from entering in ventilating system
Result in blockage, thus guarantee equipment can continuous, safe handling, improve the reliability of equipment.
6, valve plate is connect by the utility model by strengthening connecting plate and connecting cylinder with shaft, reinforcing connecting plate and valve plate
Contact area is bigger, therefore reinforcing connecting plate is bigger to the support force and pulling force of valve plate, on the one hand guarantees the leakproofness of valve plate, keeps away
Exempt to leak out；On the other hand the stability of raft plate during rotation then can be improved.
7, it is connected between the connecting cylinder of the utility model and shaft by connecting bolt, is convenient for changing different raft plates, is dropped
The difficulty of low plant maintenance.

Specific embodiment
The utility model will be described further by specific embodiment below:
Embodiment 1
Most preferred embodiment of the present embodiment as the utility model adjusts it discloses a kind of novel pressure and mends air-valve, tool
Body structure is as depicted in figs. 1 and 2, including valve body 1, and air inlet 2 and air inlet 3, the air inlet 2 are provided on the valve body 1
It is fixedly installed air inlet short tube 10, the input end of air inlet short tube 10 is fixedly installed filter screen 11；Pass through rolling in the valve body 1
The rotation of bearing 8 is provided with shaft 4, and shaft 4 is fixedly connected with connecting tube 13 by connecting bolt, is welded in the connecting tube 13
Two pieces of reinforcing connecting plates 12 being parallel to each other, the top surface for strengthening connecting plate 12 are welded with valve plate 5,
The outlet end of the valve plate 5 and air inlet short tube 10 is mutually agreed with, to realize the sealing to air inlet 2；The shaft 4
One end reach outside valve body 1, and this section of shaft 4 is fixedly connected with adjusting screw rod 6 with pin shaft by split pin, adjusting screw rod 6
