Abstract
A valve body structure for centre-pivoted butterfly valve, the bolt comprising upper valve body, lower valve body and lower valve body is arranged on upper valve body.The valve body structure of centre-pivoted butterfly valve of the present utility model adopts opposite opened structure, and upper valve body and lower valve body can remove and install easily, realizes fast assembling.
Description
Technical field
The utility model relates to a kind of valve body structure, particularly relates to a kind of valve body structure of centre-pivoted butterfly valve.
Background technique
Current centre-pivoted butterfly valve valve body is overall structure, if butterfly plate and valve shaft are butterfly plate integral structure, then cannot assemble.If during the assembling of assembling rubber valve seat, completely by extruding, easily cause the damage of rubber valve seat, and under this configuration, rubber valve seat compressibility is non-adjustable.
Model utility content
For above-mentioned existing problem, the purpose of this utility model is to provide a kind of valve body structure being easy to the centre-pivoted butterfly valve assembled.
For reaching above-mentioned technique effect, technical solution adopted in the utility model is: a kind of valve body structure of centre-pivoted butterfly valve, the bolt comprising upper valve body, lower valve body and be arranged on by lower valve body on upper valve body.
The valve body structure of centre-pivoted butterfly valve of the present utility model adopts opposite opened structure, and upper valve body and lower valve body can remove and install easily, realizes fast assembling.
Accompanying drawing explanation
Fig. 1 is the partial cross section figure of the valve body structure of centre-pivoted butterfly valve.
Embodiment
Be described further below in conjunction with the valve body structure of accompanying drawing to centre-pivoted butterfly valve of the present utility model.
Refer to Fig. 1, the valve body structure of centre-pivoted butterfly valve of the present utility model comprises upper valve body 1, lower valve body 2 and connects the bolt 3 of upper valve body and lower valve body.Wherein upper valve body 1 and lower valve body 2 are symmetrical arranged.Upper valve body 1 and lower valve body 2 side are all formed with corresponding mounting ears, and mounting ears offers mounting hole, and upper valve body 1 is arranged on lower valve body 2 through mounting hole by bolt 3.Upper valve body 1 and lower valve body 2 depart from center intended distance in conjunction with plane machining, suitably can adjust the compressibility of rubber valve seat during assembling, make valve seal reach best.Meanwhile, upper valve body 1 and lower valve body 2 embedded SMA actuators have dovetail groove, closely interlock with rubber valve seat dovetail groove, fixing rubber valve seat, prevent rubber valve seat from floating at inner chamber and are pulled phenomenon generation.
The valve body structure of centre-pivoted butterfly valve of the present utility model adopts opposite opened structure, and upper valve body and lower valve body can remove and install easily, realizes fast assembling.Rubber valve seat assembling need not extrude again, and rubber valve seat damage ratio reduces to zero, and processing cost reduces.It is adjustable that the valve body structure of centre-pivoted butterfly valve of the present utility model can realize rubber valve seat compressibility simultaneously, butterfly valve uses a period of time, rubber valve seat weares and teares, and valve seal can be made to reach best, can also prevent rubber valve seat from floating and be pulled by adjustment rubber valve seat compressibility.
The above; for better case study on implementation of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure change, all still belong in the protection domain of technical solutions of the utility model.
