Description
Technical field
What the present invention relates to is a kind of flow control valve, particularly be a kind of can be continuously, the gas flow regulating valve of dynamic adjustments fast.
Background technique
At present, more about the product category of gas flow regulating valve both at home and abroad, for example: Electromagnetic Flow modulating valve, its implementation be, at an end of valve core rod the stainless steel shell fragment is housed, under state of a control not, shell fragment returns to formation state naturally, and when the other end by the electromagnetic attracting force valve core rod overcomes the shell fragment pulling force, valve core rod will produce trace movement, the movement travel of the big or small control valve core bar by electromagnetic force, the size in hole reaches the purpose of regulating flow thereby control is dammed.
Chinese patent ZL00201013.5 discloses a kind of magnetic suspension attraction type gas flow regulating valve mouth device, is provided with large and small circular valve port coaxial and the mutual parallel placement of axle on the valve port body.Envelope is made up of the curve of at least one section arbitrary shape in the axial cross section between big valve port and little valve, and the valve block of band permanent magnet places the big valve port outside, and magnetcisuspension has the magnetic conduction spool between valve block and large and small valve port.Described magnetic conduction spool can be the magnetic conduction solid of rotation that magnetic conductive ball or its cross section external frame are made up of at least one section curve, thus but arbitrary decision gas flow linearity.
This valve is easy to be corroded because shell fragment directly places fluid, and in order to reach certain elasticity, shell fragment processing usually is thinner, and long time continuous working can produce fatigue and cause flexibility decrease to influence the service behaviour of valve.Because the movement travel of shell fragment is minimum, only is fit to less range of flow and regulates.Also some utilizes the mode of threaded screw rod, its implementation is, threaded screw rod one end places mouthful place of damming, the other end links to each other with stepper motor by slide bar, when motor rotates, drive the threaded screw rod rotation, the feeding degree of controlling its operation reaches the size of controlling the mouth that dams, realize Flow-rate adjustment, in order to reach the higher flows degree of regulation, its screw thread must be processed very fine, and pitch is usually at a few tenths of a mm, the modulating valve of this method is owing to be subjected to the restriction of pitch, when needs wide range dynamic adjustments, its speed of response is slower, in addition, superfine screw thread can make its quick-wearing very in the continuous dynamic adjustment process, the working life of having reduced valve.
In view of above-mentioned defective, creator of the present invention has obtained the present invention finally through research and practice for a long time can be continuously, the gas flow regulating valve of quick dynamic adjustments.

Embodiment
Below in conjunction with accompanying drawing, be described in more detail with other technical characteristics and advantage the present invention is above-mentioned.
See also shown in Figure 1ly, it is for the three-dimensional exploded view of gas flow regulating valve of the present invention; It comprises a modulating valve main body 4, it is provided with an air inlet nozzle 2 and an outlet nozzle 3, the setting of these two valves and described modulating valve main body 4 can be that one-body molded (the present invention does not give unnecessary details this, can realize for a person skilled in the art by casting or welding), also can be independent mutually with described modulating valve main body 4; One valve core rod 8, it is arranged in the described modulating valve main body 4, by a gland 9 described modulating valve main body 4 is sealed; An and valve core rod actuating mechanism, in order to the closed intensity of the described valve core rod 8 of regulating and controlling with described air inlet nozzle, control the effective drift diameter that it dams mouthful, thus control gaseous from the inlet of described air inlet nozzle 2, the amount of the gas that final control is gone out from described outlet nozzle 3.
For described valve core rod actuating mechanism, it should comprise power mechanism, and present embodiment is selected stepper motor 5, also can adopt actuating motor certainly, controls the rotating speed of described stepper motor 5 output shafts and turns to by it, and the corresponding action State Selection is provided; Also comprise: one is positioned at the constant acceleration cam 6 of described modulating valve main body 4 inside, and it is connected with the output terminal of described power mechanism; Also comprise: it is set in a spring 7 on the described valve core rod 8, the internal fixation position of one end and described modulating valve main body 4 leans, the end of the other end and described valve core rod 8 leans, and the original compressive state that is in is in order to provide restoring force to described valve core rod 8.Described power mechanism is if adopt stepper motor 5 to be arranged on described modulating valve main body 4 hollow inner chamber ends, and its step pitch scope should be 0.2 degree to 1.5 degree through calculating the best; Described constant acceleration cam 6 places described modulating valve main body 4 hollow inner chambers, its number of degrees the best of effectively working be 0 degree to 300 degree, need to prove above-mentioned data based concrete physical dimension and the requirement of the gas flow that needs, corresponding variation can be arranged.
In this figure, described air inlet nozzle 2 and outlet nozzle 3 are individual components, therefore corresponding described modulating valve main body 4 one ends axially have two air nozzle holes with overlooking on the face, the other end is the hollow inner chamber, described air inlet nozzle 2 is separately positioned on the corresponding described air nozzle hole with described outlet nozzle 3, fix by the valve tightening cover, and adjust the setting depth of air inlet nozzle 2.
See also shown in Figure 2ly, it is the schematic cross-section of gas flow regulating valve of the present invention, its be at above-mentioned Fig. 1 in each structure member exploded view, be outstanding internal structure, reflect the function corresponding principle and disclosed; Wherein, described air inlet nozzle 2 has a gradient at the end near inner chamber, described valve core rod 8 one ends have the awl end that matches with described air inlet nozzle 2 gradients simultaneously, on two inclined-planes immediate the time, both are mutual driving fits, flow out from described outlet nozzle 3 thereby do not have gas, when described valve core rod 8 is done motion away from air inlet nozzle 3 directions vertically, then the air gap owing to both becomes big, thereby more gas is flowed out from described outlet nozzle 3; For how making described valve core rod 8 produce corresponding motion, it is by the decision of the structural feature of described constant acceleration cam 6, because described constant acceleration cam 6 has the motion feature of rise and backhaul, therefore the other end of described constant acceleration cam 6 outer rims and described valve core rod 8 is leant, in the transfer process of the backhaul of described constant acceleration cam 6 and rise, the directions that described valve core rod 8 is determined along described modulating valve main body 4 inside are advanced or are retreated, because the existence of described pressure spring 7 can make described valve core rod 8 be in the backhaul process at described constant acceleration cam 6 and reset.
Gas flow regulating valve of the present invention can carry out dynamic response, degree of regulation height and wide ranges continuously, fast, and simple in structure, and critical component is direct contacting fluid, can realize clean air and have the flow control of certain corrosive gas.
The above only is preferred embodiment of the present invention, only is illustrative for the purpose of the present invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes to it in the spirit and scope that claim of the present invention limited, revise, even equivalence, but all will fall within the scope of protection of the present invention.
