Description
Technical Field
The utility model relates to a butterfly valve, in particular to exempt from welded ventilation butterfly valve's valve plate structure.
Background
The butterfly valve is a dust removal accessory which is flexible to use, is manufactured by welding steel plates, has the characteristics of short structural size, compact structure, small flow resistance, large flow capacity, light weight, convenience in installation and the like, and plays a role in controlling or adjusting medium gas. The expansion gap between the valve plate and the valve body is large, and the phenomenon of locking caused by expansion with heat and contraction with cold can be effectively prevented.
The valve plate of the existing ventilation butterfly valve comprises a plate body, a pair of semicircular arc grooves, a pin shaft and a valve shaft sleeve, wherein the valve shaft sleeve consists of the pair of semicircular arc grooves; the pin shaft is inserted into the valve shaft sleeve and fixed by screws, the valve shaft sleeve is formed by welding a pair of arc-shaped grooves, and the coaxiality can not meet the technical requirements. In the use process, the valve shaft is easy to twist and break due to different shafts.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a exempt from welded ventilation butterfly valve's valve plate structure replaces original welded fastening mode through the bolt fastening mode.
The technical scheme is as follows: the utility model relates to a valve plate structure of a welding-free ventilation butterfly valve, which comprises a plate body and a valve shaft; the valve shaft is characterized in that the valve shafts are used in pairs, the plate body is provided with a valve shaft shell used for limiting the valve shafts, and the valve shafts, the plate body and the valve shaft shell are fixedly connected through pin shafts.
Further, the valve shaft is provided with an installation groove, and the valve shaft is inserted into the plate body through the installation groove.
Furthermore, the plate body is provided with a plurality of rib plates for increasing the integral strength of the valve plate, and the rib plates are connected with the plate body through pin shafts.
Furthermore, part of the rib plates are provided with arc grooves, the rib plates are attached to the surface of the valve shaft through the arc grooves, and the rib plates, the valve shaft, the plate body and the valve shaft shell are fixedly connected through pin shafts.
Furthermore, a connecting column with a pin shaft hole is arranged in the rib plate, and the rib plate and the plate body are connected through the connecting column to improve the connection stability and strength of the rib plate and the plate body.
Has the advantages that: compared with the prior art, the utility model: the valve plate is mounted in a pin shaft fixing mode, the mounting difficulty of the valve shaft is reduced, and the problem that the plate body is warped in the welding process is solved; the rib plate not only can increase the strength of the valve plate, but also can limit and fix the valve shaft, and the stability of the valve shaft is improved.
Drawings
FIG. 1 is a schematic structural diagram of a valve plate structure of a welding-free ventilation butterfly valve;
fig. 2 is a bottom view of a valve plate structure of a welding-free ventilation butterfly valve.
Detailed Description
As shown in fig. 1 and 2, a valve plate structure of a welding-free ventilation butterfly valve comprises a plate body 1 and a valve shaft 2; the valve shafts 2 are used in pairs, the valve shaft shell 3 used for limiting the valve shafts 2 is arranged on the plate body 1, and the valve shafts 2, the plate body 1 and the valve shaft shell 3 are fixedly connected through pin shafts.
In order to increase the connection strength between the valve shaft 2 and the plate body 1, the valve shaft 2 is provided with a mounting groove 4, the valve shaft 2 is inserted into the plate body 1 through the mounting groove 4, and the connection strength between the valve shaft and the plate body is increased by increasing the connection length between the valve shaft and the plate body.
In order to increase the strength of the valve plate per se and ensure that the valve plate per se does not deform under a high-pressure environment, a plurality of rib plates 5 used for increasing the overall strength of the valve plate are arranged on the plate body 1, and the rib plates 5 are connected with the plate body 1 through pin shafts.
The rib plate 5 not only can increase the strength of the valve plate, but also can be used for fixing the valve shaft 2, therefore, part of the rib plate 5 is provided with an arc-shaped groove, the rib plate 5 is attached to the surface of the valve shaft 2 through the arc-shaped groove, and the rib plate 5, the valve shaft 2, the plate body 1 and the valve shaft shell 3 are fixedly connected through the pin shaft.
In order to increase the connection strength between the plate body 1 and the rib plate 5, a connecting column with a pin shaft hole is arranged in the rib plate 5, and the rib plate 5 and the plate body 1 are connected through the connecting column so as to increase the connection stability and strength of the rib plate 5 and the plate body 1.
Parts of the valve plate: the rib plate 5, the valve shaft 2, the plate body 1 and the valve shaft shell 3 are fixedly installed in a pin shaft fixing mode, so that the problem that the plate body 1 is warped in the welding process is solved; meanwhile, the rib plates 5 not only can increase the strength of the valve plate, but also can limit and fix the valve shaft 2, and the stability of the valve shaft 2 is improved.
