Abstract

The utility model relates to a regulating valve which comprises a valve body, a valve core, a valve rod, a valve cap and a handle. The utility model has the essential technical proposal that the valve core is a cylinder on which a through hole is arranged; when the valve is switched on, the through hole is communicated with a pipeline; the upper end of the valve core is provided with a T-shaped slot seat, and one end of the valve rod is provided with a T-shaped plug which is arranged in the T-shaped slot seat of the valve core. The utility model has the characteristics of no lifting devices, small size, high efficiency and clear display of regulating amount.

Description

Modulating valve

The utility model relates to a kind of valve, especially for the modulating valve of slurry delivery line.

At present, the modulating valve that is used for the slurry delivery line is flashboard type and brake tube formula structure, and it is the adjusting that realizes valve by the upper and lower displacement of spool, and the defective of existence is a range of lift big (referring to spool), volume is big, efficient is low, in addition, regulated quantity also is difficult for grasping.

The purpose of this utility model provides that a kind of spool need not to promote, volume is little, efficient is high and can know the modulating valve that shows regulated quantity.

The modulating valve that the utility model provides, comprise valve body, spool, valve rod, valve gap and handle, technological points is that spool is a cylinder, be installed in the valve body perpendicular to the valve body pipeline, on this cylinder, open a through hole, when valve was in opening state, this through hole communicated with valve pipeline, and the spool upper end is equipped with T type groove seat.One end of valve rod is a T type plug, and this T type plug is installed in the T type groove seat of spool, and the other end of valve rod is equipped with handle.

Compare with prior art, the utility model only needs rotatable handle, can drive the adjusting with flow of closing that spool rotation realizes valve by valve rod.From the opening state to the closed condition, only the handle half-twist is got final product, very convenient, improved efficiency.The utility model need not lifting gear, so volume greatly reduces.In addition, the angle of observing the handle rotation just can be known the size of grasping the valve regulated amount.

Below in conjunction with accompanying drawing the utility model is illustrated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the plan view of spool T type groove seat among Fig. 1;

Fig. 3 is the worm's eye view of valve rod T type plug among Fig. 1.

See Fig. 1, the utility model comprises valve body 4, spool 7, valve rod 2, valve gap 3 and handle 1.The spool 7 that is installed in the valve body 4 is a cylinder, and the center line of cylinder is perpendicular to the center line of valve body 4 pipelines 5; Cylinder outer wall closely contacts with valve body 4, and cylinder rotates in valve body 4; Open a through hole 6 on this cylinder, the center line of this through hole 6 and this cylinder center's line intersect and are vertical, when valve is in opening state, this through hole 6 and valve 4 pipelines with communicate.The upper end of spool 7 is equipped with T type groove seat 9, sees Fig. 2, and this T type groove seat 9 is installed in the upper end of spool 7 by floor.Valve rod 2 is installed on the valve gap 3, and an end that extend into the valve rod 2 in the valve body 4 is a T type plug 8, sees Fig. 2, and this T type plug 8 is installed in the T type groove seat 8 of spool 7.The other end of valve rod 2 is equipped with handle 1.Handle with sleeve 1 can drive spool 7 by valve rod 2 and rotate.When spool 7 turned to certain position, the through hole 6 on the spool 7 communicated fully with pipeline 5 on the valve body 4, and at this moment, valve is in opening state.Be rotated further handle 1, spool 7 also rotates thereupon, the pipeline 5 on the through hole 6 on the spool 7 and the valve body 4 communicate partly that (area) also reduces thereupon, promptly the flow of valve is also corresponding reduces.When spool forwards certain position to, through hole on the spool 76 fully with valve body 4 on pipeline 5 do not communicate, valve is in closed condition at this moment.

Claims

1. a modulating valve comprises valve body, spool, valve rod, valve gap and handle, it is characterized in that: spool is a cylinder, be installed in the valve body perpendicular to the valve body pipeline, on this cylinder, open a through hole, when valve is in opening state, this through hole communicates with valve pipeline, and the spool upper end is equipped with T type groove seat; One end of valve rod is a T type plug, and this T type plug is installed in the T type groove seat of spool, and the other end of valve rod is equipped with handle.
