Abstract
The utility model belongs to the technical field of valve plates and in particular relates to a pin-free hollow valve plate. The pin-free hollow valve plate comprises a pin-free valve plate, wherein an upper valve shaft groove and a lower valve shaft groove which are connected with a valve shaft and are coaxial with each other are formed in the upper and lower ends of the pin-free valve plate; the pin-free valve plate comprises an upper panel and a lower panel which are arc-shaped; after the upper panel and the lower panel are connected, a hollow structure matched with the arc shape of the upper panel and the lower panel is formed inside the pin-free valve plate; multiple columnar supporting pieces are uniformly arranged in the hollow structure. By adoption of the pin-free hollow structure, the weight is greatly lightened, and the production cost is reduced, so that the valve is light and flexible in the installation and transport processes, and the wear resistance is guaranteed compared with a traditional pin design. Because the weight of the valve plate is greatly reduced, the torque of the valve is reduced, the valve is easily opened and closed, and the service life of the valve is greatly prolonged.
Description
Technical field
The utility model belongs to valve plate technical field, is specifically related to a kind of without the hollow valve plate of pin.
Background technique
The stainless steel valve plate that tradition is used on butterfly valve, has been pin surface plate.Because meet the pressure that medium passes through, so all compare consume material in valve plate design.Such as the butterfly valve stainless steel valve plate used of DN400, in the time of meeting kilogram pressure of 16Kg, substance will be not less than every of 34Kg.
Because the weight of valve plate is large, strengthened cost of production, and valve install and transportation process in light and flexible not, and because the weight of valve plate is large, valve torque is increased, valve light and flexible not when opening and closing, the working life of valve is relatively short; In addition, there is pin surface plate owing to adopting pin joint, can cause the corrosivity of valve plate.
Model utility content
The purpose of this utility model is to overcome above-mentioned technical problem and provides a kind of without the hollow valve plate of pin, and being intended to solve has the weight of pin plane valve plate large at present, consume material cost high technology problem.
For achieving the above object, the utility model adopts following technological scheme:
A kind of without the hollow valve plate of pin, comprise without pin valve plate, the described upper and lower end without pin valve plate is respectively arranged with upper valve shaft groove and the lower valve shaft groove of the concentric for being connected with valve shaft, a described top plate and the lower panel that is arc shape that comprise without pin valve plate, after described top plate is connected with lower panel, described, without pin valve plate inside, be formed with the hollow-core construction that the arc shape with described top plate and lower panel adapts, in described hollow-core construction, be laid with equably a plurality of pillar supporting elements.
The outer surface middle part of described top plate and lower panel is provided with arc reinforced layer.
Described upper valve shaft groove and lower valve shaft groove are circular hole slot.
The diameter of described upper valve shaft groove is less than the diameter of described lower valve shaft groove.
Describedly without the hollow valve plate of pin, adopt stainless steel casting to form.
The utility model valve plate is owing to adopting without pin hollow-core construction, weight significantly alleviates, reduced cost of production, make valve install and transportation process in light and flexible more, than traditional, there is pin design more secure in corrosion resistance, because valve plate has significantly reduced in weight, valve torque is reduced, valve is more free and relaxed when opening and closing, and has greatly extended the working life of valve.
Accompanying drawing explanation
Figure 1 shows that the structural representation of the hollow no-pin valve plate that the utility model embodiment provides;
Figure 2 shows that Fig. 1 is along the sectional view of A-A line;
Figure 3 shows that Fig. 1 is along the sectional view of B-B line;
Figure 4 shows that Fig. 3 is along the sectional view of C-C line.
Embodiment
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Shown in Fig. 1～4, a kind of without the hollow valve plate of pin, comprise without pin valve plate 1, the described upper and lower end without pin valve plate is respectively arranged with the upper valve shaft groove 16 and lower valve shaft groove 17 of the concentric for being connected with valve shaft, a described top plate 11 and the lower panel 12 that is arc shape that comprise without pin valve plate, after described top plate 11 is connected with lower panel 12, described, without pin valve plate 1 inside, be formed with the hollow-core construction 13 that the arc shape with described top plate 11 and lower panel 12 adapts, in described hollow-core construction 13, be laid with equably a plurality of pillar supporting elements 15.
Further, described top plate 11 is provided with arc reinforced layer 14 with the outer surface middle part of lower panel 13.
Further, described upper valve shaft groove 16 is circular hole slot with lower valve shaft groove 17.
Further, the diameter of described upper valve shaft groove 16 is less than the diameter of described lower valve shaft groove 17.
In the utility model embodiment, describedly without the hollow valve plate of pin 1, adopt stainless steel casting to form.
Hollow no-pin valve plate described in the utility model, making in weight is that the stainless steel valve plate of DN400 reduces to every of 22Kg equally, greatly reduces cost of production.
Have pin plane valve plate to compare with traditional stainless steel, the utility model has following beneficial effect:
1, weight significantly alleviates and has reduced cost of production, make valve install and transportation process in light and flexible more.
2, because being to have pin design more secure in corrosion resistance without pin design than traditional.
3, because valve plate has significantly reduced more than 1/3rd in weight, valve torque is reduced, valve is more free and relaxed when opening and closing, and has greatly extended the working life of valve.
4, stainless steel without pin valve plate profile, be designed to streamlined, the vision class of whole valve that looked more full very large lifting.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
