Abstract
The invention relates to a balance valve for an automatic flow controller. The speed reduction combination comprises a motor, a base, a worm screw, a worm wheel, a screw rod sleeve and a nut; the valve body combination comprises a valve body, an inlet flange, an outlet flange and a support; the valve combination comprises a valve seat, a valve rod, a valve sleeve and a screw rod; wherein a through hole as part of a fluid channel is formed transversely in the valve seat, and a taper hole provided with larger upper part and smaller lower part and communicated to the inner cavity of the valve body is formed vertically. The motor drives the speed reduction mechanism according to the command of a control system, and the worm screw and the worm wheel drive the valve rod to be raised and dropped to realize flow regulation and maintain the set value. Because the valve seat, the valve rod and the valve sleeve are in a vertical linear row and the fluid channel comprises the valve seat and a transverse pipeline coaxial with the flange, equal diameter at any position can be realized; with the assistance of a balancing cavity structure, the fluid can not impact the pipe wall, therefore, the fluid can flow out circularly and linearly, without shearing and noise.

High pressure flow auto-controlling apparatus has metering and regulates the dual functions of control flow rate, wherein regulates and controls by equilibrium valve and realize.The linear of existing equilibrium valve output is bad, and the shearing phenomenon is arranged, and the fluid stable performance is bad, and noise is arranged, and is unfavorable for metering.
[summary of the invention]
The present invention proposes a kind of new equilibrium valve structure can overcome above-mentioned defective.
Technological scheme of the present invention is: a kind of equilibrium valve of automatic flow controller, comprise the combination of slowing down, valve body combination and valve combination, and it is characterized in that:
The combination of slowing down is made up of motor, support, worm screw, worm gear, screw mandrel cover and nut, and motor is fixed on the support, and motor shaft connects worm screw, and worm-wheel shaft has internal thread to socket screw mandrel cover in the screw mandrel cover, and nut is anchored on the end of screw mandrel cover, the worm and wheel engagement;
The valve body combination is made up of valve body, suction flange, outlet(discharge) flange and support, and suction flange and outlet(discharge) flange are symmetrically located at the valve body both sides, and two flange center positions are fluid passages, and the valve body upper end connects support, and the support upper end connects the support of the combination of slowing down;
The valve combination is made up of valve seat, valve rod, valve pocket and screw mandrel, valve seat is cylindrical, be horizontally placed in the valve body, be provided with through hole in the valve seat in the horizontal, on vertical, be provided with the up big and down small taper hole that leads to body cavity as a fluid passage part, through hole and taper hole connect, valve pocket is lining in body cavity, and the built-in valve rod of valve pocket, the taper hole of tapered head in valve rod lower end and valve seat constitute the even part of sealing, the valve rod upper end connects screw mandrel, the internal thread engagement that screw mandrel extends the screw mandrel cover and overlaps with screw mandrel.
Further, the conical nose of valve sleeving inner wall and valve rod surrounds a counter balance pocket, and conical nose has endoporus from bottom to top and has connecting tube to be communicated to counter balance pocket.
Further, the diameter of described fluid passage equates everywhere.
Motor Access Control System of the present invention preestablishes flow value as required, and motor drives reducing gear by the control system instruction, and worm and gear drives the valve rod ascending, descending and realizes Flow-rate adjustment, keeps setting value.To be a vertical line in line because of valve seat, valve rod, valve pocket, and the fluid passage is made of valve seat and flange transverse uniaxial pipeline, and can accomplish that diameter equates everywhere, be aided with the counter balance pocket structure again, fluid is unlikely to impact tube wall, so the fluid ring-type is flowed out, be linear, do not have and shear, noise free.Fabricated structure good manufacturability of the present invention, assembling, easy to maintenance can be used with any flowmeter.
