Specific embodiment
In order to be better understood from this utility model, with reference to specific embodiments and the drawings, this utility model is entered with traveling one
The description of step.
As shown in Figure 1-2, a kind of butterfly valve with cushioning effect, including valve body 4 with positioned at the butterfly plate within described valve body 4
6, it is designed with the good liner of anti-wear performance 5, described valve body 4, described liner 5 and institute between described valve body 4 and described butterfly plate 6
State and inside butterfly plate 6, be plugged with valve rod 3.The top of described valve rod 3 is provided with shaft coupling 2, and described shaft coupling 2 is also associated with being driven
Bar, the end of described drive link is fixedly connected with the hydraulic regulating device 1 for providing described valve rod 3 rotational power.Described hydraulic pressure
Modulator 1 passes through that described drive link drives described valve rod 3 and the described butterfly plate 6 that is connected with described valve rod 3 is rotated.Institute
Offer in the circular end face stating butterfly plate 6 multiple for allowing fluid to pass through the cushion hole 6.1 of described butterfly plate 6, described round nose
Reinforcement 6.2 is additionally provided with face.
In this utility model, by arranging described cushion hole 6.1, make to have and pass through described butterfly plate compared with the fluid of strong impact force
Described butterfly plate 6 can be initially passed through by described cushion hole 6.1 when 6, thus considerably reducing described butterfly plate 6 to bear described fluid
Percussion.Afterwards, then the flow velocity of fluid is made to obtain by the opening angle that described hydraulic regulating device 1 adjusts described butterfly plate 6 good
