Background technology
Ball type butlerfly valve is that a kind of structure type is butterfly valve structure, and sealing pair is a kind of valve of spherical surface, i.e. sealing surface of valve plate
For spherical surface, sealing surface of seat is the conical surface.Ball type butlerfly valve is double eccentric structures, using sealing pair wedging principle, when valve is closed,
The dirty or dirt extension being deposited on sealing surface of valve plate can be cut away, to ensure the cleaning of sealing surface.Make currently on the market
Ball type butlerfly valve is mainly by main parts sizes groups such as valve body, valve seat trim ring, valve seat, valve plate, valve seat insert, upper lower valve shafts
At.Sealing between valve seat and valve body mainly has two kinds of forms of end face seal and radial seal, radial seal can realize medium compared with
Big active force realizes valve self sealss, to reduce the open and close torque of valve convenient for valve by medium active force.
Currently, butterfly ball valve has been used widely in sewage disposal, municipal administration, power generation, chemical industry pipe network system, flap
It is packed into from outlet, valve seat and valve seat trim ring are packed into from import.Valve seat trim ring is flange-type structure, in order to ensure valve body structure size
Reasonable design, valve seat trim ring must use undergauge to design, and otherwise it is even to will appear local became uneven for valve body wall thickness, brings in design
Casting flaw, while this structure due to using undergauge design, the negotiability of valve can reduce, for water system,
This structure influences whether the medium parameter of live downstream process system.
Invention content
To achieve the goals above, the technical solution adopted in the present invention is：A kind of Ball type butlerfly valve, including driving device,
Valve body, valve shaft, valve seat and valve plate offer the cavity for accommodating the valve plate in the valve body, and the valve plate is movably arranged on institute
It states in cavity, eccentric on the valve plate to connect the valve shaft, the driving device drives the valve plate to rotate by the valve shaft；
The valve base sealing is arranged on the inner wall of the cavity, and the valve plate constitutes dynamic sealing pair with the valve seat,
The valve seat trim ring for compressing the valve seat is additionally provided on the inner wall of the cavity and for limiting the valve seat trim ring
Valve seat trim ring baffle ring；The outer of the valve seat trim ring baffle ring is embedded in the inner wall of the cavity, the valve seat trim ring baffle ring
Side fit with the valve seat trim ring；
It is additionally provided with preloading spring between the valve seat and the valve seat trim ring, stays and sets between the valve seat and the valve seat trim ring
There is compensation gap；
The pre-loading screw for valve seat described in top pressure is provided on the valve seat trim ring, the bottom end of the pre-loading screw is pressed on institute
It states on the one side of valve seat, step is provided on the inner wall of the cavity, the another side of the valve seat is in the pre-loading screw
Under the action of can fit with the step.
Based on above-mentioned, compression spring is also arranged between the pre-loading screw and the valve seat trim ring.
Based on above-mentioned, the valve shaft includes upper valve shaft and lower valve shaft, and the upper valve eccentric shaft is mounted on the upper of the valve plate
Portion, the lower valve shaft are eccentrically mounted at the lower part of the valve plate, and the top of the upper valve shaft is connected with the driving device.
Based on above-mentioned, the upper valve shaft and the lower valve shaft are in contact by sliding bearing with the valve body.
Based on above-mentioned, the driving device is Electric Actuator, pneumatic actuator, hydraulic executer or manually performs machine
Structure.
Based on above-mentioned, sealing ring is provided on the valve seat, the valve seat is sealingly disposed in described by the sealing ring
On the inner wall of cavity.
The present invention progress with substantive distinguishing features outstanding and conspicuousness compared with the prior art, specifically, of the invention
The Ball type butlerfly valve provided is equipped on valve seat trim ring by being equipped with preloading spring between valve seat and valve seat trim ring and pre-tightens spiral shell
Nail is provided with valve seat trim ring baffle ring in valve seat trim ring, and is equipped with certain gap surplus in valve seat and valve body endface, as
The mobile displacement space of valve seat floating, is equipped with certain space between valve seat and valve seat trim ring, compress and stretch as preloading spring
The space opened up space, while valve seat being also used as to float so that Ball type butlerfly valve using eccentric wedging principle and medium active force certainly
Sealing structure realizes lock-bit, makes reversed sealed reliable.
Specifically, the geometric center biasing one of the sealing spherical surface of the valve body of the Ball type butlerfly valve and the valve plate centre of gyration and valve plate
A radial dimension also has a biasing size, Ball type butlerfly valve eccentric real by two with sealing surface of seat on valve channel axis
Existing self-locking is closed.When medium is when from valve seat direction, that is, being unfavorable for sealing pressuring direction, since valve seat and valve body are radially close
Envelope, there are certain space between valve seat and valve seat trim ring, medium just fills this region, and valve seat is under medium active force, just
It is drawn close to valve plate, while when Ball type butlerfly valve installation, certain pretightning force can be equipped with to valve base sealing by pre-loading screw, thus
Reliable sealing is realized under initial stage pretightning force and medium force effect.
When medium presses from the valve plate back side, valve plate is drawn close under medium active force to valve seat, since the back side of valve seat has
The support of pre-loading screw, so under medium power, valve plate can realize good sealing effect with valve seat.Importantly, the valve
Seat trim ring is designed using unified internal diameter, is avoided undergauge structure, is improved the negotiability of valve, and existing spherical butterfly can be substituted
Valve or butterfly valve sewage disposal and city planting ductwork application, as reliably controlling fluid shutoff and flow-rate adjustment in pipe network system
Device.
The Ball type butlerfly valve is compact-sized, easy to process；There is convenient for installation and maintenance, good airproof performance simultaneously, reliability is high, and
And it can be with on-line maintenance, convenient for more than ground operating.
