Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of high leak tightness flow control valve.
Background technique
Flow control valve is for pipelines such as various hydraulic pressure, gas circuits, for regulating the flow of fluid, gas, yet the precision of now general flow control valve adjust flux is lower, in some pipeline, need to regulate more accurately rated flow, common flow control valve is all to realize coarse adjustment, the amount of movement of spool is difficult to control accurately, because Flow-rate adjustment is that spool need to be often mobile, after long-term mobile wearing and tearing, can cause sealability to reduce simultaneously.
Model utility content
Flow control valve degree of regulation of the prior art is low, the deficiency of poor sealing performance in order to overcome for the utility model, provides a kind of good airproof performance, the high leak tightness flow control valve that degree of regulation is high.
To achieve these goals, the utility model adopts following technological scheme:
A kind of high leak tightness flow control valve, comprise valve body, valve pocket, in described valve body, be provided with the flashboard of blocking-up valve pocket, the surrounding of flashboard is provided with guide housing, one end of flashboard is fixedly connected with connecting rod, the outer end of connecting rod is through being slidably connected between guide housing and guide housing, in valve body, be also provided with the adjustable lever that regulates flashboard folding size by rotation, four inner sides of guide housing are all provided with guiding groove, the bottom of guiding groove is provided with Stamping Steel Ribbon, the surrounding of described flashboard extends to form the guiding raised line coordinating with guiding groove, the positive and negative bi-side of flashboard are concordant with the two sides of guide housing, the end cross-sectional of guiding raised line is V-shaped, one of them side of guiding raised line is provided with ball grooves, in described ball grooves, be provided with row's ball.
Adjustable lever can drive flashboard to move in guide housing while rotating, thereby adjust flux is big or small, flashboard in general flow control valve or adjustable lever are directly contained in valve body, long-term friction sealed property can decline, in this structure, increase independently guide housing, good seal performance between flashboard and guide housing, wear-resistant, resistance when ball can reduce flashboard and pulls.
As preferably, in described adjustable lever, be provided with tapped hole, in tapped hole, be provided with double-screw bolt, described connecting rod is coaxially fixedly connected with double-screw bolt, the side of described adjustable lever is provided with axial limiting groove, valve body side is provided with the position limit pin stretching in axial limiting groove, the side of adjustable lever is also provided with circumferential locating slot, the bottom even of described circumferential locating slot is provided with circumferential locating tooth, described valve body side is provided with spring pin, the head of spring pin is tapered, the most advanced and sophisticated position of spring pin head is stretched between two circumferential locating tooths, the outer end of described adjustable lever is provided with rotation adjustment sleeve.The distance that the every rotation of adjustable lever drives gate to move a pitch in one week, on adjustable lever, be circumferentially arranged the circumferential locating tooth of a circle, circumferentially the quantity of locating tooth is more than ten, every rotation one lattice tooth position, the head of spring pin moves (every rotation one lattice tooth position, a lattice tooth position, during adjusting, hand can be felt accurately), flashboard moves the pitch of ten parts, therefore can control very accurately lock hole flow, stable performance, degree of regulation is high, can be self-align by spring pin when adjustable lever is adjusted to suitable flow.
As preferably, the cross section of described connecting rod is rectangular, between the inner of described connecting rod and flashboard, is rotationally connected.Between between connecting rod and guide housing, be slidably connected, adjustable lever rotates and is, connecting rod can not rotate, and the moment of torsion on connecting rod can not pass to flashboard yet, prevents that flashboard is subject to causing flashboard both sides sealing to reduce after certain moment of torsion.
As preferably, the outer end of described valve body is also provided with protecting jacket, between described protecting jacket and valve body, is threaded.Adjustable lever Flow-rate adjustment well after, the protecting jacket of screwing on, prevents unintentional rotation adjustable lever and causes changes in flow rate.
As preferably, the folding end section of described flashboard is V-shaped, and the folding end of flashboard is also provided with some arc notch.When flashboard cuts out completely, folding end can insert in the guiding groove that guide housing is corresponding, therefore cross section is V-shaped can play leading role, is also for the ease of sealing simultaneously, when Flow-rate adjustment is to very little time, lock hole just becomes a seam, so easily by the particulate matter in medium, stopped up, and while offering arc notch, even when flow is very little, granular substance mass-energy in medium is discharged from indentation, there, thereby prevents lock hole plug.
Therefore, the utlity model has good seal performance, beneficial effect that degree of regulation is high.
