Background technology
The task of the utility model is for existing " multifunction active plug flow control valve ", is existed in use
It is big spool cylinder barrel eccentric force, since crank is using 90 degree of revolutions, its arm of force is longer, this is extremely not to the movement of spool cylinder barrel
Profit, the bias that tilting force is descended to generate thereon is easily caused, spool cylinder barrel is made to accelerate with the abrasion of throttle sleeve both ends guide ring, so as to
Influence service life.In addition spool cylinder barrel and throttle sleeve are cumbersome also there is structure in manufacture structure, excessive etc. from gravity
Problem, and circulation medium is restricted by valve flowing channel chamber, medium flow direction goes out mode using a left side into the right side, when flow of media,
Right port of export medium can generate concentration convection phenomena, this will cause droop loss big, while valve has vibration, and noise is also big,
Especially large bore valves, such issues that drawback protrude it is apparent.
The content of the invention
To overcome the above disadvantages, it is provided, and a kind of mechanism is simple, and technical perfection uses reliable, cost for the utility model
Relatively low, spool design is trapezoidal bottomless cylinder barrel by it, and has balance pressure difference, the effect of abating the noise.The utility model spool
Cylinder barrel is divided into two sections, and a section is sealing imperforate cylinder (left part), and another section is to adjust cylinder (right part) with holes, two cylinders one
Greatly, one it is small be integrated, sealed cylindrical both ends be equipped with taper sealing face, adjust cylinder be equipped with cage Cv value adjustment holes, for adjusting
Amount of restriction and noise resistance are used, and flange is additionally provided in its cylinder and is integrally bonded with twin beams.In addition throttle sleeve periphery, which is equipped with, is permitted
Multiple throttling anti-noise sound hole, it goes out greatly 1/3 than adjusting cylinder barrel aperture, and both ends span is big, favourable to be oriented to and seal, and equipped with convex
Along being guide ring and taper sealing face, it adjusts flow with the cooperation of spool cylinder barrel, and sealing medium makes valve control with multi-functional
Discharge characteristic.
The utility model is mainly made of electric device, trim, main valve body and auxiliary valve body, and main valve intracoelomic cavity is equipped with interlayer
Inner cavity, inner cavity are designed in side, are positioned by sliding shaft sleeve equipped with stent, long-pending thing of row runner mouth, valve shaft through hole, valve shaft, then by
Electric device drives 120 degree of revolutions of valve shaft, and valve shaft the inside (interlayer inner cavity) is with crank hexagonal with integrator, the insertion of valve shaft end
In rack sleeve, thus valve shaft is firmly positioned, twin beams is reconnected equipped with connecting rod, connecting rod on crank, is allowed to drive
Spool cylinder barrel moves, and realizes process or cut-out control.
The utility model is equipped with spool cylinder barrel and throttle sleeve, they are big by one, and a small cylinder combination is nested together, by two
Taper face sealing is held, throttle sleeve is crimped by auxiliary valve body flange, is fixed on main valve intracoelomic cavity interlayer end, flowed through through fluid, then
Spool cylinder barrel is driven in throttle sleeve by Denso, side-to-side movement, flow is controlled, to meet operating conditions requirement.
The utility model of simple structure and strong practicability, dependable performance, service life is long, and manufacture cost is relatively low, is to manage at present
The innovative good product thought.

Specific embodiment
Its operation principle is illustrated to the embodiment of the utility model below in conjunction with the accompanying drawings.
1. during valve opening：
Electric device 28 rotates counterclockwise, and valve shaft 3 is driven to rotate therewith, then crank 7 also rotates counterclockwise, and drives connecting rod 9
It is shaken with 11 small eccentricity of twin beams, while spool cylinder barrel 13 is moved to the left, the seal face of spool cylinder barrel 13 is gradually opened at this time, is adjusted
Section end face is also gradually opened, and so far medium flows into the bore of throttle sleeve 10 by the adjustment hole of spool cylinder barrel 13, afterwards medium
Into 1 flow passage chamber of main valve body, flowed out from valve left side, i.e.,：Valve goes to 120 degree from 0 degree, causes valve opening.
2. valve is closed：
Electric device 28 rotates clockwise, and valve shaft 3 and crank 7 is driven to rotate clockwise, shakes connecting rod 9 and twin beams 11,
Spool cylinder barrel 13 moves right at this time, then the seal face of spool cylinder barrel 13 and adjusting end face progressively close off simultaneously, form sealing,
Valve is closed in place.
The utility model " a kind of tube plug balance type flow control valve ", is to existing " multifunction active plug flow control
Raising in valve " structural change and service life, this Novel control valve thoroughly solve guide ring quick abrasion, and eccentric force is big,
The outstanding problems such as concentricity is poor, and service life is short.
