Abstract
For a throttle for steam converter valve, relate to valve technology field, what solve is the technical problem that prior art can not have quick adjustment through-current capacity performance and good Flow-rate adjustment precision concurrently simultaneously.This throttle is the cylindricality staving of about one both ends open, and the side face of throttle right part offers the through throttle orifice of multiple radial direction, it is characterized in that: described throttle orifice has two kinds, and a kind of throttle orifice is wherein a pores, and another kind of throttle orifice is two pores; A described pores is the elongate holes being parallel to throttle central axis, and described two pores are circular holes, and the sectional area of two pores is less than the sectional area of a pores; Each pores is laid around throttle central axis axisymmetric, forms a pores array, and each two pores are laid around throttle central axis axisymmetric, and form two pores arrays, two pores arrays are arranged on the right side of a pores array.The throttle that the utility model provides, is applicable to being assemblied in steam converter valve using.
Description
Technical field
The utility model relates to valve gate technology, particularly relates to a kind of technology of the throttle for steam converter valve.
Background technique
The throttle for regulating hydrodynamic pressure and flow is all provided with in the valve body of steam converter valve, throttle be arranged on valve body import and outlet between, throttle offers some throttle orifices, medium flows to valve outlet by each throttle orifice after valve body import enters, and then flow out valve body, spool is arranged in throttle, the position of regulating spool in throttle, the i.e. quantity of throttle orifice that covers in of adjustable valve core and/or the flow area of throttle orifice, thus reach the object of Flow-rate adjustment.
In existing steam converter valve, the geomery of all throttle orifices on throttle is all the same, throttle adopts large aperture throttle orifice can guarantee steam converter valve quick adjustment through-current capacity, but Flow-rate adjustment precision is poor, and throttle adopts small aperture throttle orifice can guarantee that steam converter valve possesses good Flow-rate adjustment precision, but the governing speed of through-current capacity is slower.Therefore, existing steam converter valve all can not possess good Flow-rate adjustment precision while possessing quick adjustment through-current capacity performance, and its application area is narrower, and the steam converter valve of single specification cannot tackle complicated operating mode.
Model utility content
For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of throttle for steam converter valve having quick adjustment through-current capacity performance and good Flow-rate adjustment precision concurrently.
In order to solve the problems of the technologies described above, a kind of throttle for steam converter valve provided by the utility model, this throttle is the cylindricality staving of about one both ends open, the side face of throttle right part offers the through throttle orifice of multiple radial direction, it is characterized in that: described throttle orifice has two kinds, a kind of throttle orifice is wherein a pores, and another kind of throttle orifice is two pores;
A described pores is the elongate holes being parallel to throttle central axis, and described two pores are circular holes, and the sectional area of two pores is less than the sectional area of a pores;
Each pores is laid around throttle central axis axisymmetric, forms a pores array, and each two pores are laid around throttle central axis axisymmetric, and form two pores arrays, two pores arrays are arranged on the right side of a pores array.
Further, the quantity of described two pores is more than the quantity of a pores, and the diameter of two pores is less than the width of a pores.
The throttle for steam converter valve that the utility model provides, throttle is provided with the different throttle orifice of two kinds of sectional areas simultaneously, at valve initial stage energy well control media flow and regulation quality, also the peak rate of flow requirement in valve later stage be can meet simultaneously, quick adjustment through-current capacity performance and good Flow-rate adjustment precision thus had concurrently.
Accompanying drawing explanation
Fig. 1 is the plan view of the throttle for steam converter valve of the utility model embodiment;
Fig. 2 is the sectional view of the throttle for steam converter valve of the utility model embodiment;
Fig. 3 is the application schematic diagram of the throttle for steam converter valve of the utility model embodiment.
Embodiment
Illustrate below in conjunction with accompanying drawing and be described in further detail embodiment of the present utility model, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.
As Figure 1-Figure 2, a kind of throttle for steam converter valve that the utility model embodiment provides, this throttle 1 is the cylindricality staving of about one both ends open, the side face of throttle 1 right part offers the through throttle orifice of multiple radial direction, it is characterized in that: described throttle orifice has two kinds, a kind of throttle orifice is wherein a pores 2, and another kind of throttle orifice is two pores 3;
A described pores 2 is the elongate holes being parallel to throttle central axis, described two pores 3 are circular holes, the sectional area of two pores 3 is less than the sectional area of a pores 2, and the quantity of two pores 3 is more than the quantity of a pores 2, the diameter of two pores 3 is less than the width of a pores 2, and the width of a pores 2 refers to the spacing between two long limits of a pores;
Each pores 2 is laid around throttle central axis axisymmetric, forms a pores array, and each two pores 3 are laid around throttle central axis axisymmetric, and form two pores arrays, two pores arrays are arranged on the right side of a pores array.
As shown in Figure 3, the throttle 1 of the utility model embodiment is assemblied in the interior use of valve body 4 of steam converter valve, throttle 1 be arranged on valve body import and outlet between, the spool 5 of steam converter valve is arranged in throttle 1, medium flows to valve outlet by each throttle orifice throttle 1 after valve body import enters, and then flow out valve body, the position of regulating spool 5 in throttle 1, the i.e. quantity of throttle orifice that covers in of adjustable valve core 5 and/or the flow area of throttle orifice, thus reach the object of Flow-rate adjustment;
When the inner chamber of MEDIA FLOW inlet valve body 4, owing to throttle 1 having two pores arrays, make throttle 1 in the early stage can well control media flow and regulation quality, and owing to throttle 1 having a pores array, make throttle 1 also can meet the peak rate of flow requirement in valve later stage.
