Abstract
The invention provides a butterfly plate for a three-eccentric center butterfly valve. The butterfly plate comprises a circular disc-shaped sealing body, wherein a sealing surface is formed at the circumference of the sealing body, a reinforced flow guide body fixedly connected with the sealing body is arranged at one side of the sealing body, the reinforced flow guide body consists of a reinforcing plate and connecting arms, the reinforcing plate is parallel to the sealing body, the connecting arms are respectively arranged at the two ends of the reinforcing plate, and the reinforcing plate is fixedly arranged on the sealing body through being supported by the connecting arms, so a flow guide passage allowing fluid to pass is formed between the reinforcing plate and the sealing body, and a flow guide plate supported between the reinforcing plate and the sealing body is arranged in the flow guide passage. When the butterfly plate provided by the invention is utilized, the resistance of the butterfly plate on the fluid media can be reduced. Compared with a solid butterfly plate, the butterfly plate has the advantages that under the condition of reaching the same intensity requirements, the material consumption is obviously lower than that of the solid butterfly plate, so the production cost is greatly reduced.
Description
Technical field
The present invention relates to the butterfly valve that a kind of pipeline is used, especially a kind of three eccentric butterfly valve butterfly plate.
Background technique
Butterfly valve, as the valve of opening or cutting out the medium of pipeline and equipment, plays a part regulate and dam in pipeline and equipment, at oil, and rock gas, the fields such as chemical industry have a wide range of applications.In prior art, more advanced butterfly valve is three eccentric butterfly valve, and valve body and valve seat are disjunctor member, valve base sealing surface layer built-up welding heatproof, corrosion resistant alloy material, and the soft folded formula seal ring of multilayer is fixed on butterfly plate.
As shown in Figure 1 because the eccentric A of the size of setovering between valve rod axis and butterfly plate sealing surface, and and valve channel between the size bias of setovering
b, valve seat rotational axis and valve channel axis form the eccentric C of an eccentric angle, therefore form three bias.Butterfly valve is when opening for 0 °-90 °, butterfly plate sealing surface can depart from sealing surface of seat immediately in the moment of opening, when closing for 90 °-0 °, the moment of only closing, the conical sealing surface of its butterfly plate just can contact and compress the conical sealing of valve seat, so between the sealing surface on valve seat and butterfly plate without any friction, the possibility of having removed wearing and tearing and having leaked.
This butterfly valve is compared with traditional butterfly valve also to be had high temperature resistantly, operates lightly, while closing, along with the moment of driving mechanism increases, carrys out compensation sealing, has improved the sealability of butterfly valve and the advantage increasing the service life.But in actual application, in order to guarantee butterfly plate can bear enough pressure, do not damage ring, it is very thick that the butterfly plate overall structure of this valve is done conventionally, thereby cause flow resistance large, and energy consumption is high.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of three eccentric butterfly valve butterfly plate, can make the butterfly valve of specification of the same race reduce weight, and can reduce in use the resistance of media flow, can also guarantee the working strength of butterfly valve.
The present invention is in order to solve the problems of the technologies described above, and the technological scheme adopting is: a kind of three eccentric butterfly valve butterfly plate, described butterfly plate has a discoid seal, on the circumference of sealing body, there is sealing surface, a side at sealing body, be provided with a reinforcement deflector being fixedly connected with seal, this reinforcement deflector is comprised of with the link arm that is separately positioned on stiffening plate two ends a stiffening plate that is parallel to seal, described stiffening plate is supported and fixed on seal by link arm, makes the guide channel that between stiffening plate and seal, formation is passed through for fluid.
In described guide channel, be provided with the guide plate being supported between stiffening plate and seal.
Described guide plate is plural piece, all be trapezoidal, it is obliquely installed with respect to seal, and trapezoidal short base is consistent with the length of stiffening plate and be fixedly connected with it, trapezoidal long base is connected with seal, and plural piece guide plate successively end-to-end forms the supporting structure that cross section is W shape.
Described stiffening plate is identical with the thickness of guide plate, and the thickness of the Thickness Ratio stiffening plate of described seal is large.
The thickness of described seal is 8/7 times of stiffening plate thickness.
Described link arm is provided with for the mounting hole of valve rod is installed.
Described stiffening plate the width with the perpendicular direction of guide channel be seal diameter 0.55-0.58 doubly, the 1.20-1.25 that the direction length that it parallels with guide channel is its width times.
Beneficial effect:
1, the guide channel forming between stiffening plate and seal,, can pass through for flowing medium during in opening state at butterfly valve, thereby has reduced the resistance of butterfly plate fluid medium.
2, the setting of guide channel makes to strengthen the supporting structure that deflector has hollow, compares with solid butterfly plate, is reaching under same requirement of strength, and material consumption will significantly be less than solid butterfly plate.And this hollow structure butterfly plate entity part thickness sum is also less than solid butterfly plate, and the resistance of convection cell is also less than solid butterfly plate.
3, guide plate is arranged to trapezium structure, and when butterfly valve is opened, the waist of trapezoidal plate is met to fluid, thereby makes the resistance area of guide plate convection cell be the inclined-plane of an inclination, has further reduced the resistance of fluid medium, has reduced energy consumption, thereby has reduced cost of production.
4, the W shape supporting structure that guide plate end-to-end forms has also further guaranteed the intensity of whole butterfly plate, thereby has strengthened the functional reliability of butterfly valve.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to further concrete detailed explanation.
As shown in Figures 2 to 5, a kind of three eccentric butterfly valve butterfly plate, described butterfly plate has a discoid seal 1, on the circumference of sealing body 1, there is sealing surface, a side at sealing body 1, be provided with a reinforcement deflector being fixedly connected with seal 1, this reinforcement deflector is comprised of with the link arm that is separately positioned on stiffening plate 2 two ends a stiffening plate 2 that is parallel to seal, described stiffening plate 2 is supported and fixed on seal 1 by link arm, makes the guide channel that between stiffening plate 2 and seal 1, formation is passed through for fluid.
