Abstract
The utility model discloses a kind of novel butterfly valve with hyperbolic formula port plate, comprise electric actuator, support, gland, valve seat and valve plate, described gland connection bracket and valve seat, described pedestal upper end is connected with electric actuator, the output shaft end of described electric actuator is connected with one end of valve shaft, the other end of valve shaft connects valve plate, described valve plate is installed in described valve seat, also comprise port plate and through hole, described port plate is half arc, be symmetrically distributed in the bi-side of valve plate, the port plate of every one side is two, between left and right every and be bent outwardly placement, four pieces of port plates are the distribution of hyperbolic formula, every block port plate is all provided with through hole.The utility model butterfly valve, compared to existing straight journey Linear regulating valve, has volume little, lightweight advantage.In addition, due to the effect of hyperbolic formula port plate, this butterfly valve has better linear regulating function.
Description
Technical field
The utility model relates to mechanical equipment technical field, more particularly relates to a kind of novel butterfly valve with hyperbolic formula port plate.
Background technique
Valve controls to be adjusted parts of rate-of flow, and its major function comprises: medium directly flows or medium interim path, adjustment and throttling, prevent from flowing backwards, regulating pressure, release excess pressure etc.Modulating valve is a kind of very important control valve in valve class, its Variable Control for regulating fluid to flow, in current industrial processes, as the modulating valve of the vitals of whole control system, wide variety, comprising: straight-through single-seat valve, straight-through double seated valve, three-way valve, angle row valve, ball valve, camflex valve, gate valve, butterfly valve etc.
Butterfly valve can be divided into adjustment type, cut-out type by effect and regulate cut-out type three class, and it has, and through-current capability is large, regulating ratio is large, the inferior feature of pressure drop.Original common butterfly valve is a kind of simple, and the flapper valve be not closed completely, generally not there is quick open flow characteristic, usually use as flow control valve and orifice valve in pipe-line system.
Model utility content
The utility model proposes a kind of jet-type smoke treating device, linear flow characteristic is reached by installing hyperbolic formula cone shape hole port plate on valve plate, when pressure reduction is invariable before and after valve, good linear relationship can be presented by the flow of valve and aperture.
The technical solution of the utility model is achieved in that
A kind of novel butterfly valve with hyperbolic formula port plate, comprise electric actuator, support, gland, valve seat and valve plate, described gland connection bracket and valve seat, described pedestal upper end is connected with electric actuator, the output shaft end of described electric actuator is connected with one end of valve shaft, the other end of valve shaft connects valve plate, described valve plate is installed in described valve seat, also comprise port plate and through hole, described port plate is half arc, be symmetrically distributed in the bi-side of valve plate, the port plate of every one side is two, between left and right every and be bent outwardly placement, four pieces of port plates are the distribution of hyperbolic formula.
Further, every block port plate is all provided with through hole;
Further, described through hole is spaced on the same radian line of port plate, and be at least provided with two rows, the internal diameter of every exhausting hole is equal, and is greater than the aperture of the through hole away from valve plate near the aperture of the through hole of valve plate;
Further, described through hole is tapered, and the opening of taper is inside the radian of port plate;
Further, be fixed on valve plate by gusset between described port plate, and smoothing processing between port plate and gusset.
The beneficial effect that the utility model produces is: butterfly valve of the present utility model, compared to existing straight journey Linear regulating valve, has volume little, lightweight advantage.In addition, due to the effect of hyperbolic formula port plate, this butterfly valve has better linear regulating function.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is port plate structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of novel butterfly valve with hyperbolic formula port plate as shown in Figure 1 and Figure 2, comprise electric actuator 1, support 4, gland 2, valve seat 5 and valve plate 7, described gland 2 connection bracket 4 and valve seat 5, described support 4 upper end is connected with electric actuator 1, the output shaft end of described electric actuator 1 is connected with one end of valve shaft 3, the other end of valve shaft 3 connects valve plate 7, described valve plate 7 is installed in described valve seat 5, therefore electric actuator 1 is rotated according to Automatic Control valve shaft, and the amplitude that adjustment valve rotates carries out on-off action.Also be provided with port plate 6 and through hole 8 in the utility model, described port plate 6 is half arc, is symmetrically distributed in the bi-side of valve plate 7, the port plate of every one side is two, between left and right every and be bent outwardly placement, four pieces of port plates are the distribution of hyperbolic formula, and every block port plate 6 is all provided with through hole 8.
Be spaced on the same radian line of port plate 6 as preferred embodiment through hole 8, at least be provided with two rows, the internal diameter of every exhausting hole is equal, and is greater than the aperture of the through hole away from valve plate near the aperture of the through hole of valve plate, through hole is tapered, and the opening of taper is towards in the radian of port plate.When electric actuator drives valve shaft to carry out in the process opened and closed, be good linear relationship with aperture under the effect of port plate by the flow of butterfly valve, compared to existing many straight journey Linear regulating valves, it is little that this butterfly valve has volume, lightweight advantage, this is all very important in the manufacturing, installation and operation process.
Be fixed on valve plate 7 by gusset 9 between port plate 6 in the utility model, and smoothing processing between port plate 6 and gusset 9, prevent the precision of washing away using of liquid stream in moving process from affecting.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
