Abstract
A ball valve with a controllable output flow comprises a packing gland, a hexagon bolt, a connecting rod, a step motor, a motor bolt, a step motor frame, a valve body, valve core packing and a ball valve core. Three arc channels which are evenly distributed at the angle of 120 degrees are arranged in the ball valve core. Sizes of inner diameters of the three channels are different from one another. Ports of the channels are respectively communicated with an input port and an output port of the valve body, well fit the input port and the output port of the valve body, and can precisely control flow output according to requirements. The ball valve has the advantages that under control of the step motor, one channel of the ball valve core is chosen to be used for output according to requirements, the output flow is precisely controlled, precision is high, operation is easy, and the structure is simple.
Description
Technical field
The utility model relates to a kind of ball valve, is specifically related to the controlled ball valve of a kind of output flow.
Background technique
The ordinary ball valve of prior art is to rotate to realize the switch of passage by the spheroid in the ball valve, when the passage in the spheroid is consistent with tube passage when communicating, valve is all opened, when spheroid rotates 90 ° again, when the penetration hole in the spheroid and tube passage intersect vertically, the valve Close All, when the passage in the spheroid and tube passage oblique, segment fluid flow passes through, and still, what it can't confirm by.Therefore, existing ordinary ball valve is just generally regulated flow by the crossing angle of rotating sphere passage and tube passage, and that is to say and can only regulate output flow qualitatively, and can't be from quantitatively regulating.This need control output flow flowing medium more accurately for some, and adopting ordinary ball valve is to realize.
The model utility content
At the deficiency of original design, the utility model provides a kind of output flow controlled ball valve.
For achieving the above object, the utility model adopts following technological scheme:
The ball valve that a kind of output flow is controlled comprises Gland, hex head bolt, connecting rod, stepper motor, motor bolt, stepper motor frame, valve body, spool filler, ball-type spool.
Described spherical valve in-core has three to be the circular arc passages that hexagonal angle distributes, and three-aisled internal diameter size has nothing in common with each other, and the port of passage is connected with the inlet opening of valve body and delivery outlet respectively and fits like a glove.
Described ball-type spool upper end has a square groove, the lower end of connecting rod can be embedded in the square groove of ball-type spool drive the rotation of ball-type spool, connecting rod upper end has a square groove, makes the pto of stepper motor can embed in the square groove of connecting rod and drives the connecting rod rotation.
Be surrounded by the identical spool filler of four block sizes around the described ball-type spool, there is Gland the upper end, can fully guarantee the sealing of structure, wherein, two blocks of spool fillers at valve body inlet opening and delivery outlet end respectively have a hole onesize with port, and fluid can be circulated normally.
Advantage of the present utility model is: under Stepping Motor Control, select a passage in the ball-type spool to export according to demand, reach accurate control output flow, accuracy is higher, and is easy to operate, and simple in structure.
Description of drawings
Fig. 1 is complete section structural representation of the present utility model.
Fig. 2 is sectional structure schematic representation of the present utility model.
Wherein: 1. Gland, 2. hex head bolt, 3. connecting rod, 4. stepper motor, 5. motor bolt, 6. stepper motor frame, 7. valve body, 8. spool filler, 9. ball-type spool, 10. inlet opening, 11. delivery outlets.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The utility model as shown in Figure 1 and Figure 2, the ball valve that a kind of output flow is controlled is made up of Gland 1, hex head bolt 2, connecting rod 3, stepper motor 4, motor bolt 5, stepper motor frame 6, valve body 7, spool filler 8 and ball-type spool 9.
Described stepper motor 4 is fixed on the stepper motor frame 6 by motor bolt 5, and stepper motor frame 6 and Gland 1 are fixed on the valve body 7 by hex head bolt 2; Described valve body 7 has inlet opening 10 and delivery outlet 11, and inlet opening 10 and delivery outlet 11 are 90 ° of angles at same horizontal plane and arrange.
There are three to be the equally distributed circular arc passage of hexagonal angle in the described ball-type spool 9, three-aisled internal diameter size has nothing in common with each other, can accurately control flow output on request, the port of passage is connected with the inlet opening 10 of valve body 7 and delivery outlet 11 respectively and fits like a glove.
Be surrounded by the identical spool filler 8 of four block sizes around the described ball-type spool 9, there is Gland 1 upper end, can fully guarantee the sealing of structure, wherein, two blocks of spool fillers 8 at valve body 7 inlet openings 10 and delivery outlet 11 ends respectively have a hole onesize with port, and fluid can be circulated normally.
Described ball-type spool 9 upper ends have a square groove, the lower end of connecting rod 3 can be embedded in the square groove of ball-type spool 9 drive 9 rotations of ball-type spool, connecting rod 3 upper ends have a square groove, make the pto of stepper motor 4 can embed in the square groove of connecting rod 3 and drive connecting rod 3 rotations, when stepper motor 4 rotates with hexagonal angle, wherein a passage just is connected with the passage of valve body 7 in the ball-type spool 9, realizes fluid quantitative output.
Under the prerequisite that does not break away from the utility model spirit and scope, three big I of passage internal diameter in the described ball-type spool 9 are formulated by actual demand.
