Description
Technical field
It the utility model is related to a kind of valve, the non-maintaining butterfly valve of specially a kind of sealed reliable.
Background technology
In the past, the valve of chemical industry, usually sealing property in general common valve.Common valve no matter from material also
It is that structure does not possess the characteristics of special, on the one hand the sealing property of this each sealing position of valve is bad, can not be well
Prevent dielectric leakage；On the other hand under deep-etching, poisonous and hazardous process conditions, often poor sealing performance, is easily leaked.
In addition, it is necessary to the butterfly plate more renewed when existing butterfly plate occurs contacting not close with seal receptacle, not only waste of resource,
And delay the production cycle.
Utility model content
The purpose of this utility model is to provide a kind of non-maintaining butterfly valve of sealed reliable, effectively can solve in background technology
The problem of.
Realizing the technical scheme of above-mentioned purpose is：The non-maintaining butterfly valve of sealed reliable, including valve body, butterfly plate, valve rod, worm gear
Box assembly and handwheel, axis hole is offered on described valve body, and the valve rod is mutually consolidated through described axis hole with described butterfly plate
Fixed connection, the valve interior surface are provided with the seal receptacle coordinated with dish plate, and the upper end of valve rod is connected by turbine box assembly and handwheel
Connect, it is characterised in that：Dish plate includes secondary dish plate and main dish plate, and the secondary dish plate is connected with valve rod, and the end face outside of secondary dish plate connects
Be connected to more slide bars, the main dish plate, which is engaged and slided with seal receptacle, to be set on slide bar, the main dish plate and secondary dish plate it
Between slide bar on placed spring, the threaded one end of slide bar through main dish plate is connected with stop nut.
Further, it is respectively arranged with undergauge step on the valve rod in the upper and lower axis hole of the valve body inner ring, on valve body,
Preserving and sealing circle, polytetrafluoroethylsealed sealed circle and metal support are disposed with undergauge step between lower shaft hole and valve rod from inside to outside
Circle and K-type butterfly spring.
Further, V-type fluoroplastics combined stuffing circle is provided between the valve body and valve rod, the combination of V-type fluoroplastics is filled out
Insertion ring pressing plate is provided with above feed ring, the insertion ring pressing plate is fixedly connected by bolt with valve body.
V-type fluoroplastics combined stuffing circle is provided between valve body and valve rod of the present utility model, ensures the zero leakage of medium, it is resistance to
It is strong rotten.
Butterfly plate of the present utility model is divided into two parts that main butterfly plate and secondary butterfly plate can dismount, and the sealing surface of main butterfly plate is responsible for
Formed and sealed with seal receptacle, secondary butterfly plate is responsible for connecting main butterfly plate and valve rod, only needed when convenient disassembly, being easy to safeguard, and changing
Will more change owner butterfly plate, reduce maintenance cost.
Spring is provided between main butterfly plate and secondary butterfly plate, under the action of the spring, main butterfly plate and sealing can be effectively ensured
Reliable sealing between seat, while reach non-maintaining purpose.
Preserving and sealing circle, polytetrafluoroethylsealed sealed is respectively arranged with valve rod in the upper and lower axis hole of the utility model valve body inner ring
Circle and metal bracing ring and K-type butterfly spring.Preserving and sealing circle, polytetrafluoroethylsealed sealed circle and metal bracing ring can effectively increase this
The sealing property and decay resistance of utility model, extend service life.The elastic force of K-type butterfly spring make preserving and sealing circle,
Polytetrafluoroethylsealed sealed circle and metal bracing ring reach the self-supporting compensation of sealing, form gap-free sealed mechanism, while close when reducing switch
Envelope abrasion, valve run and during the equipment cycle of operation, without changing seal, reach non-maintaining purpose.
