Description
Technical field
This utility model is related to a kind of valve and in particular to a kind of prevent sewing formula regulating valve.
Background technology
Regulating valve also known as control valve, in industrial automation process control field, by accepting regulation unit output
Control signal, go to change the final control element of rate-of flow, pressure, temperature, the technological parameter such as liquid level by power operation.
Typically it is made up of actuator and valve, regulating valve is applied to sky gas and water, steam, various Korrosionsmedium, mud, oil product etc.
Medium.
Regulating valve is mainly made up of actuator and valve, regulating valve valve part various informative, common are butterfly valve,
Ball valve, stop valve etc., when the valve part of regulating valve adopts butterfly valve, due to regulating valve life-time service, butterfly plate repeats to be opened and closed, close
Seal is easy to be deformed, and reduces the sealing of valve part, the service life of impact regulating valve.
Content of the invention
In order to solve the above problems, this utility model provides one kind to prevent sewing formula regulating valve, and this regulating valve can significantly carry
The sealing of high valve, extends its service life, reduces the use cost of regulating valve.
This utility model is achieved through the following technical solutions：
One kind is anti-to sew formula regulating valve, and including valve body, valve rod and butterfly plate, described butterfly plate is arranged at the fluid passage of valve body
Interior, butterfly plate is connected with valve rod, is provided with the valve seat corresponding with the butterfly plate in closed mode in described valve body, and valve seat is that annular is recessed
Groove, is provided with two symmetrical arc Reinforced Hoop in annular groove, described valve body each side set one recessed with annular
The screw of groove connection, the fastening bolt that valve body is externally provided with through screw and is contacted with arc Reinforced Hoop, in described fluid passage
It is stained with one layer of elastic seal ring, described valve rod is connected with a motor driver.
This utility model is by setting annular groove outside elastic seal ring and the arc that can be promoted by fastening bolt
Reinforced Hoop, available fastening bolt adjusts arc Reinforced Hoop position, and then adjust the elastic seal ring of annular groove corresponding position with
The compactness of butterfly plate contact is it is ensured that the sealing of regulating valve is even closer.
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.
It is provided with top-down through hole, described valve rod lower end is through through hole and moving phase with body base in the middle part of described butterfly plate
Even.
This utility model compared with prior art, has such advantages as and beneficial effect：
This utility model is a kind of to be prevented sewing formula regulating valve, and this regulating valve passes through to arrange annular groove outside elastic seal ring
With the arc Reinforced Hoop that can be promoted by fastening bolt, available fastening bolt arbitrarily adjusts arc Reinforced Hoop position, and then adjusts
The compactness that the elastic seal ring of section annular groove corresponding position is contacted with butterfly plate, it is ensured that regulating valve sealing is even closer, works as elasticity
After sealed ring deformation, arc Reinforced Hoop can be adjusted further, so that elastic seal ring is fitted close with butterfly plate, substantially increase regulation
The sealing of valve, extends regulating valve service life.
