Embodiment
The utility model embodiment will be elaborated again by above-mentioned accompanying drawing below.
As shown in Fig. 1 ~ Fig. 3,1. valve bodies, 11. circular grooves, 12. circular holes, 2. regulation rings, 21. arc guide grooves, 22. centers lead to
Rivet post, 33. outer rivet posts, 4. bevel gear groups, 41. bevel gears, 5. drive rods, 6. in hole, 3. blades, 31. adjustable ports, 32.
Pressure measuring tie-in.
Aperture-type flow control valve, it is related to a kind of tunable component by similar to camera aperture to adjust flow
Valve, its structure are mainly made up of valve body 1, regulation ring 2, multiple blades 3 and drive rod 5 etc..
Wherein, valve body 1 has discoid profile, and in actual use, its profile can be also designed as respectively as needed
Kind shape, the interior circular groove 11 and circular hole 12 set provided with concentric as shown in Figure 1 of valve body 1, the circular hole are arranged on the groove of circular groove 11
Bottom, and circular groove 11 is penetrated vertically, therefore circular hole 12 can be as the limbers of valve body 1, to facilitate the fluid in pipeline to pass through.
Installation and adjustment ring 2 and 6 blades 3 in described circular groove 11, and regulation ring 2 is outside, 6 blades 3 are arranged on regulation
Between ring 2 and circular groove 11；The described external diameter of regulation ring 2 is slightly less than the internal diameter of circular groove 11, and it is past freely can to determine angle in the interior work of circular groove 11
Multiple to rotate, the constituted mode of its rotational power is：Drive rod 5 is arranged on the outer upper of valve body 1, the lower end of drive rod 5 passes through
Default aperture is stretched into circular groove 11 and as the inner on valve body 1, and the drive rod is inner to be set respectively between the outer face of regulation ring 2
There is the equipped bevel gear group 4 of engagement, and bevel gear 41 is only arranged on the outer face of regulation ring 2 by a bit of, and the bevel gear
41 radian is slightly larger than or the curved angle equal to arc guide groove 21, therefore the positive and negative rotation of drive rod 5 is with regard to that can drive regulation ring 2
Work determines angle reciprocating rotation.
Meanwhile the upper end of drive rod 5 which is provided with multiple driving structures and driven to operate as the outer end being exposed at outside valve body 1
The positive and negative rotation of lever, common type of drive is included manually, electrically or pneumatically, and manual actuation mode is in drive rod outer end
Handwheel is installed, and the flow coefficient k v values corresponding to each turned position are marked on handwheel, to improve the behaviour of Flow-rate adjustment
Make accuracy.
In addition, being additionally provided with 6 arc guide grooves 21 for making circumference uniform distribution for the center of circle with central through hole 22 in regulation ring 2, this 6
Individual arc guide groove size shape is identical, and along the circumferential direction bending in the same direction, i.e. simultaneously towards counterclockwise shown in Fig. 2
Bending；6 described blades 3 are also circumferentially uniform, and blade quantity must be identical with the quantity of arc guide groove 21, to form one
Installation relation corresponding to one, it is specifically：The middle part of each blade 3 is hingedly mounted on corresponding arc by middle rivet post 32 and led
Into groove 21, the outer end of each blade 3 is hingedly mounted on valve body 1 by outer rivet post 33；Therefore, middle rivet post 32 can edge
Arc guide groove 21 is slided, therefore its position is variable, and outer rivet post 33 is hingedly mounted on valve body 1, thus its position determine it is constant；
The inner of 6 blades 3 extends internally and encloses an adjustable port 31 jointly simultaneously.
When the positive and negative rotation of drive rod 5 outside operating valve body 1, with regard to regulation ring 2 can be driven to make to determine angle reciprocating rotation, and drive
Middle rivet post 32 reciprocatingly slides along arc guide groove 21, then each blade 3 surrounds the outer synchronous axial system of rivet post 33, so as to
So that the inner of 6 blades 3 encloses either large or small adjustable port 31 jointly, that is, change the section face of adjustable port 31
Product, it is achieved thereby that Flow-rate adjustment.
The pressure measuring tie-in 6 for being located at the both sides of adjustable port 31 respectively is additionally provided with outside the valve body 1 of the aperture-type flow control valve, then
Using professional equipment, by pressure measuring tie-in 6 with regard to the pressure differences of the both sides of adjustable port 31 can be measured, and with the flow coefficient k v originally tested
Value compares, and flow is calculated.
The utility model both can be individually attached is used for Flow-rate adjustment on pipeline, may be mounted to static balancing valve or dynamic again
The entrance of balanced valve, form adjustable balancing valve.
