Description
Technical Field
The utility model relates to a ball core, especially a two V type opening ball cores.
Background
As shown in fig. 1-2, in order to meet the requirements of working conditions and processes in the coal chemical industry, the conventional ball core is of a fan-shaped structure, and the fan-shaped ball core rotates to shield or open a hole body on a valve core on a valve seat to realize the circulation or cut-off of media; but the flow regulating performance of the conventional ball core is poor;
in conclusion, how to adjust the flow rate of the ball core medium becomes a problem which needs to be solved urgently by researchers in the field.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how to realize the adjustability of the medium flow of the ball core;
in order to solve the technical problem, the utility model discloses the technical scheme who takes does:
the utility model relates to a two V type opening ball cores, include: the center of the flow channel penetrates through the center of the sphere; a first V-shaped opening which is opened at one side of the end of the flow channel and communicated with the flow channel; the insertion groove is formed in the top of the sphere and is used for inserting the rotating shaft;
in the scheme, the end part of the rotating shaft is arranged in the insertion groove, and the rotating shaft rotates to control the self-rotation angle of the ball core; when the ball core rotates, part of the first V-shaped opening is communicated with the upper hole body of the valve body, a medium can enter the flow channel from the first V-shaped opening, and when the rotating angle of the ball core is larger, the medium passes through the flow channel in the flow channel and is also larger; when the flow hole and the hole body are coaxial, the valve body is in a fully opened state at the moment, and the flow reaches the upper limit;
the first V-shaped opening is formed in one side of the end portion of the flow channel, and an inclined wall is obliquely arranged on one side of the flow channel to form the first V-shaped opening.
The ball core is also provided with a second V-shaped opening, and the side edge of the end part of the other end of the flow channel is provided with the second V-shaped opening; the first V-shaped opening and the second V-shaped opening are arranged in a rotational symmetry mode by taking the sphere center of the sphere as the center;
the first V-shaped opening and the second V-shaped opening are consistent in shape and structure and are arranged in a rotational symmetry mode, so that the flow direction of the medium is not required, and the medium can enter from the second V-shaped opening to achieve flow regulation; in addition, the inner wall of the flow channel is completely smooth and does not cause medium blockage.
The utility model has the advantages that: the utility model relates to a two V type opening ball cores, the opening has been seted up at spheroidal middle part, and the tip both sides rotational symmetry of opening is provided with first V type opening, second V type opening, so, can realize medium flow's adjustable through rotating the spheroid.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a top view of a conventional structure;
FIG. 2 is a rear view of a conventional structure;
fig. 3 is a cross-sectional view of the present invention;
fig. 4 is a three-dimensional view of the present invention;
in the figure: 1-first V-shaped opening, 2-second V-shaped opening, 3-flow channel, 4-insertion groove.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 3-4, the utility model relates to a two V type opening cores, include: the center of the sphere is provided with a flow channel 3 in a penetrating way, and the center line of the flow channel 3 penetrates through the sphere center of the sphere; a first V-shaped opening 1 which is opened at the end portion side of the flow channel 3 and is communicated with the flow channel 3; an insertion groove 4 which is provided at the top of the sphere and into which the rotating shaft is inserted;
in the scheme, the end part of the rotating shaft is arranged in the insertion groove, and the rotating shaft rotates to control the self-rotation angle of the ball core; when the ball core rotates, part of the first V-shaped opening is communicated with the upper hole body of the valve body, at the moment, a medium can enter the flow passage from the first V-shaped opening, and when the rotating angle of the ball core is larger, the medium passes through the flow passage in the flow passage; when the flow hole and the hole body are coaxial, the valve body is in a fully opened state at the moment, and the flow reaches the upper limit;
the first V-shaped opening is formed in one side of the end portion of the flow channel, and an inclined wall is obliquely arranged on one side of the flow channel to form the first V-shaped opening.
As shown in fig. 3, the ball core is further provided with a second V-shaped opening 2, and the end side of the other end of the flow channel 3 is provided with a second V-shaped opening 3; the first V-shaped opening 1 and the second V-shaped opening 2 are arranged in a rotational symmetry mode by taking the sphere center of the sphere as the center;
the first V-shaped opening and the second V-shaped opening are consistent in shape and structure and are rotationally and symmetrically arranged, so that the flow direction of the medium is not required, and the medium can enter from the second V-shaped opening to realize flow regulation; in addition, the inner wall of the flow channel is completely smooth and does not cause medium blockage.
The utility model relates to a two V type opening ball cores, the opening has been seted up at spheroidal middle part, and the tip both sides rotational symmetry of opening is provided with first V type opening, second V type opening, so, can realize medium flow's adjustable through rotating the spheroid.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
