Set, the link position between the second valve body and transparent tube body not will form joint gap, flowed to reduce fluid media (medium)
The vibration caused in the process and noise extend the service life of the double ball valves of visual duplex.
Be further arranged to: the fixing piece include across the first valve body and transparent tube body, the second valve body with it is transparent
The bolt of tube body and the nut being connect with bolt thread.
By using above-mentioned technical proposal, bolt attaching nut generate clamping force for realizing the first valve body with it is transparent
Fixation between tube body, between the second valve body and transparent tube body.
Be further arranged to: in the runner of first valve body be located at the second valve body runner in it is fixed
There are the first guided rings for contradicting sealing ring end face.
By using above-mentioned technical proposal, the setting of the first guided rings plays drainage to the fluid media (medium) flowed into, subtracts
Fluid media (medium) strikes against sealing ring end face and the noise caused and vibration in few flowing.
Be further arranged to: the cross-sectional shape of first guided rings is right angled triangle.
By using above-mentioned technical proposal, the first guided rings of the shape can play the fluid media (medium) in flowing best
Drainage effect.
Be further arranged to: between first valve body and transparent tube body, between the second valve body and transparent tube body
Equipped with gasket.
By using above-mentioned technical proposal, the setting of gasket between the first valve body and transparent tube body, the second valve body
Two sealing effects are played between portion and transparent tube body, to reach better seal performance.
It is further arranged to: being installed with the second guided rings for contradicting sealing ring end face on the inner ring wall of the transparent tube body.
By using above-mentioned technical proposal, the setting of the second guided rings plays drainage to the fluid media (medium) flowed into, subtracts
Fluid media (medium) strikes against sealing ring end face and the noise caused and vibration in few flowing.
In conclusion the utility model has the following beneficial effects: the utility model can be right by the setting of transparent tube body
