Abstract
The utility model discloses a flow control ball valve, which comprises the following components: a valve body, be provided with disk seat and case in the valve body, the disk seat is discoid, be equipped with the recess in the radial direction of disk seat, the degree of depth of recess increases to the other end from one end gradually to set up fluid inlet at the recess end, fluid inlet communicates with each other with the recess, the utility model discloses a valve holder structure can realize the accurate regulation of ball valve low discharge.
Description
Technical field
The utility model relates to a kind of control valve changing flow, particularly relates to a kind of Flow-rate adjustment ball valve.
Background technique
Modulating valve has another name called control valve, in industrial automation process control field, by accepting the control signal that regulation unit exports, removes by power operation the final control unit changing the process parameters such as rate-of flow, pressure, temperature, liquid level.Generally be made up of actuator and valve, if press stroke feature, modulating valve can be divided into straight journey and angle stroke.Traditional adjustment ball valve is all adopt spool opens " V " shape mouth to play regulatory role, but to minor adjustment valve small guide vane and control valve for small flows adjusting function not ideal, as long as because when spool one turn-on flow rate is just from the directly outflow of " V " shape opening moment, because it is little that opening shape can not be worked into enough essences, so for modulating valve small guide vane and control valve for small flows control characteristic poor, do not have good regulating action.Cause and regulate the using scope of ball valve to be subject to certain limitation, so for control valve for small flows or require that the higher modulating valve of small guide vane requirement also can only select straight travel regulating valve, but straight travel regulating valve is high relative to ball valve cost, weight is large wait not enough.
China Patent No. is separately had to be 201320350944.2, the day for announcing is that 2013.12.18 discloses a kind of Flow-rate adjustment valve core, one end of described Flow-rate adjustment valve core is poppet head, described poppet head is a cylindrical body, and described poppet head is provided with at least one groove, the degree of depth of described groove increases gradually on the direction of the fluid inlet towards described flow control valve.The flow control valve valve core structure that the utility model provides is simple, easy to process and can realize controlling the highi degree of accuracy of tiny flow quantity.Above-mentioned model utility adopts straight travel regulating valve structure, but linear motion valve is high relative to ball valve cost, and weight is large.
Model utility content
In order to overcome the defect of above-mentioned prior art, the utility model provides a kind of Flow-rate adjustment ball valve, and this adjustment ball valve can realize ball valve small-flow precise and regulate.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of Flow-rate adjustment ball valve, comprise valve body, valve seat and spool is provided with in described valve body, it is characterized in that: described valve seat is discoid, described valve seat be provided with groove in the radial direction, the degree of depth of described groove from one end to the other side increases gradually, and arranges fluid inlet in notch end, and described fluid inlet communicates with groove.
The width of described groove increasing gradually on the direction of fluid inlet, V-shaped.
Described fluid inlet is arranged on the darkest one end of groove.
The utility model has the following advantages:
One: realize ball valve small-flow precise and regulate: for modulating valve adjusting function, usual ball valve adjusting function is not as straight travel regulating valve, poorer for ordinary ball valve structure control characteristic small flow, the relative common valve stand structure of present valve seat construction, flexible design opening shape and the opening degree of depth can be required according to duty parameter, have opening shape and the opening degree of depth two adjustable parameters regulate, conventional ball valve can only be regulated by opening shape adjustable parameter, regulates so valve seat construction of the present utility model can realize ball valve small-flow precise.
Two: improve ball valve small guide vane control characteristic: it is not so good that conventional ball valve exists small guide vane modulability characteristic, particularly for equal percentage flow characteristic, below 10%, aperture Flow characteristics is undesirable especially, because conventional construction can only carry out adjust flux from the size of " V ", owing to regulating ball valve to be the aperture being carried out control valve by the angular dimension of the rotation of ball core, flow is there is from the phenomenon without anxious increasing during small guide vane, so adjusting function is poor during small guide vane, according to above-mentioned existing problems, the valve seat construction opening degree of depth of the present utility model according to valve opening to closed position, the opening degree of depth is from shallow to deeply, when small guide vane, flow not only can control from opening shape like this, can also from opening severity control flow, be equivalent to many Primary regulations, the flow anxious phenomenon increased just is there is not during small guide vane, thus effectively improve small guide vane control characteristic.
Three: expand and regulate ball valve using scope: high modulating valve and control valve for small flows are required for adjusting function, usual employing straight travel regulating valve structure, but linear motion valve is high relative to ball valve cost, weight is large, adopt valve seat construction of the present utility model for control valve for small flows, or adjusting function requires that high modulating valve may select ball-valve structure all completely, thus reduce costs, therefore expand and regulate ball valve using scope.

Fig. 2 is valve seat construction schematic diagram of the present utility model;
Fig. 3 is that the A-A of Fig. 2 is to sectional view;
Mark in figure: 1, valve body, 2, valve seat, 3, spool, 4, groove, 5, fluid inlet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment 1
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of Flow-rate adjustment ball valve, Flow-rate adjustment ball valve of the present utility model is rotary motion valve, it comprises valve body 1, valve seat 2 and spool 3 is provided with in described valve body 1, described valve seat 2 is discoid, described valve seat 2 be provided with groove 4 in the radial direction, the degree of depth of described groove 4 from one end to the other side increases gradually, and fluid inlet 5 is set at the end of groove 4, described fluid inlet 5 communicates with groove 4, described fluid inlet 5 is arranged on the darkest one end of groove 4, the width of described groove 4 increases gradually on the direction towards fluid inlet 5, V-shaped.
Above-mentioned valve seat 2 is sealed and matched with spool 3, and when closing adjustment ball valve, spool 3 and valve seat 2 fit tightly and seal groove 4 and fluid inlet 5, and fluid cannot pass through; When opening adjustment ball valve, namely spool 3 turns an angle, the groove 4 of V-arrangement is opened gradually, liquid groove 4 passes through, and because the groove 4 opening degree of depth is from shallow to deeply, when small guide vane, flow not only can control from opening shape like this, can also from opening severity control flow, be equivalent to many Primary regulations, just there is not the flow anxious phenomenon increased during small guide vane, thus effectively improve small guide vane control characteristic.
