Abstract
The utility model discloses a reinforcing rib structure for a valve plate of a butterfly valve, which comprises a plurality of horizontal reinforcing ribs along the fluid direction, which are arranged on the valve plate. The valve plate is also provided with a plurality of longitudinal reinforcing ribs which are crossed with the horizontal reinforcing ribs. Aiming at the defects of an existing valve plate reinforcing rib structure, the utility model designs the reinforcing rib structure for the valve plate of the butterfly valve, which can be used for effectively promoting the integral structural intensity of the valve plate and promoting working reliability of the valve plate. The integral reinforcing rib structure has the advantages of high intensity, low flow resistance and low hydrodynamic head loss.
Description
Background technique
The utility model relates to butterfly valve plate, is specially the reinforcing rib structure of butterfly valve plate.
Background technique
For large-diameter butterfly valve, because it need bear bigger hydrodynamic pressure when using, its valve plate is easy to generate distortion and reduces functional reliability, and therefore often needing to design stiffening rib increases valve plate intensity.
As shown in Figure 1, at present stiffening rib 11 ' distribution form to be mainly the flow direction that is parallel to internal flow be main, its objective is the influence that as far as possible reduces when increasing valve plate 1 ' intensity flowing, make fluid drop to minimum by the hydrodynamic head loss of valve.
But above stiffening rib 11 ' structure only can strengthen the structural strength of valve plate 1 ' longshore current body flow direction, and the valve plate 1 ' structural strength perpendicular to fluid flow direction there is no too many reinforing function.
The model utility content
At the problems referred to above, the utility model has designed a kind of reinforcing rib structure of butterfly valve plate, and it can effectively promote the overall construction intensity of valve plate, promotes the functional reliability of valve plate.
For achieving the above object, the utility model is by the following technical solutions:
A kind of reinforcing rib structure of butterfly valve plate comprises it is characterized in that the horizontal stiffener of the some roads longshore current body direction that is arranged on the valve plate: also be provided with the waling that some roads and horizontal stiffener are crisscross arranged on the described valve plate.
Further, be provided with some roads horizontal flowing hole consistent with direction of flow simultaneously on the above-mentioned waling or on the horizontal stiffener or on two kinds of stiffening ribs.
The utility model is provided with some roads waling on the basis of horizontal stiffener, waling is the vertical setting of horizontal stiffener or the setting of inclination several angle relatively, both are interlaced to link together, this structure arranges, can strengthen the valve board structure intensity of longshore current body direction and other directions simultaneously, promote the functional reliability of valve plate.
At this, the setting of waling can make the flow resistance of fluid and hydrodynamic head loss increase, and makes the service behaviour of valve that certain reduction be arranged.Be head it off, the utility model is being provided with horizontal flowing hole on the waling or on the horizontal stiffener or on two stiffening ribs simultaneously, horizontal flowing hole and direction of flow are consistent, such structure setting, can be under the prerequisite that does not reduce valve plate intensity, effectively increase the fluid of unit time through the flow of valve, reduce the hydrodynamic head loss that brings because of the waling setting.
Description of drawings
The schematic representation of reinforcing rib structure on Fig. 1, the existing valve plate;
Fig. 2, reinforcing rib structure schematic representation of the present utility model;
The structural representation of flowing hole is set on Fig. 3, the utility model reinforcing rib structure.
Embodiment
As shown in Figure 2, a kind of reinforcing rib structure of butterfly valve plate comprises the horizontal stiffener 11 of the some roads longshore current body direction that is arranged on the valve plate 1, also is provided with the waling 12 that some roads and horizontal stiffener 11 are crisscross arranged simultaneously on the valve plate 1.At this, in the present embodiment, horizontal stiffener 11 and waling 12 all are set to twice, form " # " type structure, in actual use, can corresponding reinforcement chewiness number be set according to valve plate 1 actual size.
The utility model valve plate 1 is provided with some roads waling 12 on the basis of horizontal stiffener 11, described waling 12 is horizontal stiffener 11 vertical settings or the setting of inclination several angle relatively, and both are interlaced to link together.Above structure setting can strengthen the overall construction intensity of valve plate 1 longshore current body direction and other directions simultaneously, can effectively promote the functional reliability of valve plate 1.
At this, the setting of waling 12 can make the flow resistance of fluid and hydrodynamic head loss increase, and makes the service behaviour of valve that certain reduction be arranged.Be head it off, can be provided with horizontal flowing hole 111 simultaneously on the waling 12 or on the horizontal stiffener 11 or on two stiffening ribs, in the present embodiment, be provided with horizontal flowing hole 111 on horizontal stiffener 11 and the waling 12 simultaneously, horizontal flowing hole 111 is consistent with direction of flow, such structure setting, can be under the prerequisite that does not reduce valve plate 1 intensity, effectively increase the fluid of unit time through the flow of valve, reduce the hydrodynamic head loss that brings because of waling 12 settings.
To sum up, the deficiency that the utility model exists at existing valve plate reinforcing rib structure, designed a kind of reinforcing rib structure of butterfly valve plate, it can effectively promote the overall construction intensity of valve plate, promote the functional reliability of valve plate, it is big that whole reinforcing rib structure has intensity, and flow resistance is little, the advantage that the hydrodynamic head loss is few.
The above, it only is preferred embodiments of the present utility model, be not that model utility is done any pro forma restriction, every foundation know-why of the present utility model still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations or modification that above embodiment does.
