Road and gas piping.
Such as Chinese patent application（Publication number：CN205859176U）Disclose and " a kind of butterfly valve body and the valve is installed
The butterfly valve of body ", it is characterized in that the passage set including valve body body and through valve body body, the passage include feed end,
Is provided with valve seat in the passage, is rotated in the passage and be provided with valve rod, be fixed with valve plate on the valve rod, the valve plate outside
Circumference is provided with the sealing ring coordinated with valve seat, and the valve seat is arranged on the feed end in passage, the end face of the valve seat and valve
The end face of body body is set.Valve seat is arranged on feed end, at work, fluid first passes through valve seat, then enters back into logical
In road, due to being that the circulation area of valve seat is less than the circulation area of passage, so rapid into the fluid can in valve seat
Diffusion, will not be detained in passage, the impurity in fluid and dust can be avoided to drop near passage and valve seat, can be with
Effectively reduce valve seat and ring wear, extend the service life of valve seat and sealing ring, but valve rod and flap fixed form
It is excessively simple.
