Description
Technical field
The present invention relates to a kind of three eccentricity regulating butterfly valve.
Background technology
Because the monomer engineering of petrochemical enterprise is increasing, various pipe diameters constantly increase；Gas transmission oil pipeline
Continue to develop, the scale of hydraulic engineering expands day by day, the demand of heavy caliber control valve is continuously increased.Straight travel range control valve, ball
More than the valve aperture DN300 such as valve product is all very heavy, and butterfly valve size is small, lightweight, therefore sales volume gradually increases.In city
Promotion under, control valve manufacturer updates butterfly valve structure, after having been occurred as soon as in the product that last century the eighties are introduced
Seat type butterfly valve, occurs in that three-eccentric-butterfly-valve, along with valve positioner function is big after there are two eccentric-butterfly-valves, the nineties later
Big to improve, the unbalanced moments that substantially overcomes butterfly valve is big, stability is poor, the big shortcoming of leakage class low three, adds its body
Small, the lightweight advantage of product is into global advantage, so in large bore valves field, butterfly valve is preferred product.
Traditional butterfly valve is normally manufactured as switch valve and used, and during as regulating valve, butterfly valve is not easily adjustable due to small guide vane, general
The regulating ratio of logical butterfly valve typically only 20：1 or so (ball-shaped regulating valve is essentially 50：1), because butterfly valve is in small guide vane situation
Under, the pressure difference before valve and after valve is larger, is more also easy to produce cavitation.
The content of the invention
A kind of three eccentricity regulating butterfly valve is provided the present invention seeks to the defect existed for prior art.
The present invention to achieve the above object, is adopted the following technical scheme that：A kind of three eccentricity regulating butterfly valve, including valve body, institute
State body base and be provided with valve seat, the valve body top is provided with valve rod, the valve rod be applied in the valve body and with setting
Valve plate in the valve body is fixedly connected；Wherein, the valve plate includes the valve plate body and pressing plate being fixedly connected, the valve plate
Provided with elastic sealing element between body and the pressing plate, the sealing surface of the outer peripheral face of the elastic sealing element and the valve seat is top
Angle identical scalene cone；The tune of the valve rod central rotation can be surrounded by the valve plate by being welded with the outside of the edge of the valve plate
Nodal pattern deflector；Wherein, multiple apertures for being used to control flow are drilled with the adjustment type deflector, the aperture of the aperture exists
Between 2-5mm.
Beneficial effects of the present invention：The present invention is simple in construction, and the circulation of valve small guide vane can be realized using deflector,
Also respective degrees reduce noise.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
Shown in Fig. 1, it is related to a kind of three eccentricity regulating butterfly valve, including valve body 1, the bottom of valve body 1 is provided with valve seat 2, institute
State the top of valve body 1 and be provided with valve rod 3, the valve rod 3 be applied in the valve body 1 and with the valve plate that is arranged in the valve body 1
It is fixedly connected；Wherein, the valve plate includes the valve plate body 4 and pressing plate 5 being fixedly connected, the valve plate body 4 and the pressing plate 5
Between be provided with elastic sealing element 6, the sealing surface of the outer peripheral face of the elastic sealing element 6 and the valve seat 2 is drift angle identical
Scalene cone；The adjustment type that the central rotation of valve rod 3 can be surrounded by the valve plate by being welded with the outside of the edge of the valve plate is led
Flow plate 7；Wherein, multiple apertures for being used to control flow are drilled with the adjustment type deflector 7, the aperture of the aperture is in 2-
Between 5mm.
When valve opening, by control and regulation type deflector, the circulation of valve small guide vane can be realized using deflector
Amount, also respective degrees reduce noise.And the aperture (aperture is preferably between 2-5mm) set on deflector can be by liquid
Flow is controlled in the range of very little, as the change of opening is so as to obtain different degrees of flow.The three of the present invention are inclined
Heart regulating butterfly valve can be applied to high pressure, High Pressure Difference, require VI grade of leakage class or No leakage operating mode can according to operating mode from
By change orifice plate quantity, stage distance, throttle diameter.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
