Technical field
The present invention relates to a kind of adjusting butterfly valve, especially a kind of pneumatic adjusting butterfly valve of accurate flow adjustment.
Background technique
The tradition butterfly valve usually only uses as switch valve, but along with the development of chemical plant installations more and more demonstrates digitizing, intellectuality, high-precision trend, and the adjusting function of butterfly valve and reliability, stability have been proposed very high requirement.In prior art, traditional butterfly valve plate all adopts ball valve lip seal technology, uses polymeric material or elastic metallic ring valve seat to cooperate the effect that reaches sealing with the spherical outer rim of valve plate.This butterfly valve structure adjusting function is poor, regulation range is narrower, even does not possess adjusting function, causes that wastage of material is serious in the production process, manufacturing efficiency is low, and the butterfly valve negotiability is big, be difficult for advantage such as obstruction can't find full expression.Therefore can't satisfy some the adjusting function of valve is required operating modes of increasingly stringent, even influence complete equipment and normally move, cause heavy economic losses.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the existing technology.Exclusive equal percentage characteristics curved valve plate cooperates Field bus and digital control technology, uses highly sensitive, highi degree of accuracy air bladder formula actuator, realizes medium is carried out accurate flow control.The present invention can substitute big and heavy single seat, the sleeve adjusting valve of many volumes in the operating mode that requires big negotiability, has both practiced thrift cost, guarantees that again apparatus moves safely and smoothly simultaneously, enhances productivity.
According to technological scheme provided by the invention; A kind of pneumatic adjusting butterfly valve of accurate flow adjustment; Comprise valve body and valve plate; Be separately installed with transmission shaft and driven shaft in the axis hole at said valve body two ends, said valve plate is installed in the runner hole of valve body, and the two ends of valve plate are installed in respectively on transmission shaft and the driven shaft; Characteristic is: said valve plate comprises the outer rim of sector shape spherical in shape, the ridge shape convexity that is the edge contour of circular arc spherical surface shape and is arranged on the edge contour two ends, between convexity and edge contour, forms the level and smooth curved surface that links up.
In the runner hole of said valve body, be provided with counterbore; Seal ring and seal ring are set in counterbore; Seal ring and seal ring are pressed on the valve body through trim ring, and seal ring and seal ring are arranged between valve body and the valve plate, and the outer rim of said valve plate matches with the endoporus of seal ring.
Said valve body is connected installation positioner in air bladder formula actuator through connecting support with air bladder formula actuator.
First lining is set between said transmission shaft and valve body, and by packing seal, filler is compressed by Gland between transmission shaft and the valve body.
Second lining is set between said driven shaft and valve body.
Compared with present technology the present invention has the following advantages:
1, regulation range of the present invention is 15%～75% of a valve stroke, is 3 times of traditional butterfly valve (30%～50%);
2, the present invention has accurate equal percentage characteristics adjustment curve, and the control of equipment more is provided with a little near industrial pressure;
3, the present invention is equipped with sensitive air bladder formula actuator, and positioning work piece has been selected the FISHER6000F series of positioners of the total line traffic control of most advanced in the world FF for use, can realize remote online debugging, fault diagnosis functions; Annexes such as speed increaser, solenoid valve, lock valve, Pneumatic valve have been realized the best of breed of model and relevant parameter also through repeatedly test, guarantee that this product has very outstanding adjusting function;
4, application area of the present invention is wider, its both had traditional butterfly valve negotiability big, advantage such as be difficult for stopping up, in light weight, have outstanding adjusting function again, can substitute big, the heavy and expensive single seat of many volumes, sleeve adjusting valve, practice thrift cost.

Embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
Like Fig. 1～shown in Figure 5: the pneumatic adjusting butterfly valve of accurate flow adjustment comprises valve body 1, valve plate 2, seal ring 3, seal ring 4, trim ring 5, screw 6, transmission shaft 7, fixing pin 8, driven shaft 9, connects support 10, air bladder formula actuator 11, positioning work piece 12, outer rim 13, edge contour 14, protruding 15, curved surface 16, first lining 17, filler 18, Gland 19, second lining 20 etc.
The present invention includes valve body 1 and valve plate 2, said valve body 1 is connected with air bladder formula actuator 11 through connecting support 10, in air bladder formula actuator 11, positioning work piece 12 is installed; Be separately installed with transmission shaft 7 and driven shaft 9 in the axis hole at said valve body 1 two ends; First lining 17 is set between transmission shaft 7 and valve body 1; By filler 18 sealings, filler 18 is compressed by Gland 19, and second lining 20 is set between driven shaft 9 and valve body 1 between transmission shaft 7 and the valve body 1;
Said valve plate 2 is installed in the runner hole of valve body 1, and the two ends of valve plate 2 are installed in respectively on transmission shaft 7 and the driven shaft 9, and fixing through fixing pin 8;
