Description
Technical field
The present invention relates to a kind of valve, be specifically related to one and prevent sewing formula electric butterfly valve.
Background technology
Butterfly valve is again flap valve, is the regulation valve of a kind of simple in construction, can be used for the on-off control of low pressure pipeline medium
Butterfly valve refers to that closure member is disk, around valve shaft rotate reach open and close a kind of valve, valve can be used for control air,
The flowing of all kinds fluids such as water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium,
Cut-out and throttling action is acted primarily as on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, around the axle of himself in valve body
Line rotates, thus reaches to open and close or the purpose of regulation.
Existing butterfly valve, generally includes valve body, valve rod and butterfly plate, and butterfly plate is arranged in the fluid passage in valve body, logical
That crosses butterfly plate and sealing ring coordinates the sealing realizing fluid passage.Due to butterfly valve life-time service, butterfly plate repeats opening and closing so that seal
Circle is deformed, and reduces the sealing of butterfly valve, affects its service life.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of and prevents sewing formula electric butterfly valve, and this electric butterfly valve can significantly carry
The sealing of high valve, extends its service life, reduces use cost.
The present invention is achieved through the following technical solutions:
Preventing sewing formula electric butterfly valve, including valve body, valve rod and butterfly plate, described butterfly plate is arranged in the fluid passage of valve body, butterfly plate
Being connected with valve rod, be provided with the valve seat corresponding with the butterfly plate in closed mode in described valve body, valve seat is annular groove, in annular
Being provided with two symmetrical arc Reinforced Hoop in groove, described valve body each side sets a spiral shell connected with annular groove
Hole, valve body is externally provided with through screw the fastening bolt that contacts with arc Reinforced Hoop, is stained with one layer in described fluid passage
Elastic seal ring, described valve rod and a motor driver are connected.
The present invention strengthens by arranging annular groove and the arc that can be promoted by fastening bolt outside elastic seal ring
Hoop, available fastening bolt regulation arc Reinforced Hoop position, and then the elastic seal ring of regulation annular groove corresponding position and butterfly plate
The compactness of contact, it is ensured that butterfly valve seal is tightr.
By being connected with butterfly valve by motor driver, automatization's regulation of butterfly valve opening and closing can be realized, time saving and energy saving.
Described elastic seal ring adheres in the fluidic channel walls in valve body, and therefore valve seal is good, it is to avoid fluid leads to
Cross annular groove and screw leaks.
Described arc Reinforced Hoop is made up of metal material, and described elastic seal ring is made up of hydrogenated nitrile-butadiene rubber.
Being provided with top-down through hole in the middle part of described butterfly plate, described valve rod lower end is through through hole moving phase with body base
Even.
The present invention compared with prior art, has such advantages as and beneficial effect:
The present invention is anti-sews formula electric butterfly valve, and this butterfly valve is by arranging annular groove and can be fastened outside elastic seal ring
The arc Reinforced Hoop of bolt pusher, available fastening bolt arbitrarily regulates arc Reinforced Hoop position, and then regulation annular groove pair
The compactness that the elastic seal ring that should locate contacts with butterfly plate, it is ensured that electric butterfly valve seals more tight, when elastic seal ring deforms
After, arc Reinforced Hoop can be regulated further, make elastic seal ring closely cooperate with butterfly plate, substantially increase the sealing of electric butterfly valve
Property, extends electric butterfly valve service life.
