Description

Technical Field

[0001] This application relates to the field of ball valve technology, and more particularly to a lightweight ball valve with a filtering function. Background Technology

[0002] A ball valve is a valve in which the valve stem drives the opening and closing mechanism, rotating around the stem's axis. Ball valves are primarily used to cut off or connect the medium in a pipeline, and can also be used for fluid regulation and control. A ball valve has a 90-degree rotation action, and the plug body is a ball with a circular through-hole or channel passing through its axis. Ball valves are mainly used in pipelines for cutting off, distributing, and changing the flow direction of the medium. They require only a 90-degree rotation and a very small torque to achieve a tight seal. Ball valves are best suited for on / off and shut-off applications, but recent developments have led to designs that allow for throttling and flow control. The opening and closing element of a ball valve is generally a ball with a through-hole in the center through which the fluid medium flows. This design is relatively expensive. During rotation, impurities in the pipeline medium may prevent the ball valve from closing completely.

[0003] Application content

[0004] The purpose of this application is to provide a lightweight ball valve with a filtering function to solve the technical problem in the prior art where impurities in the pipeline cause the ball valve to fail to close.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a lightweight ball valve with a filtering function is provided, including a valve body and a valve core, wherein the valve core is configured as an arc; both ends of the valve core are rotatably connected to the valve body through a valve stem; an installation shaft is also provided on the valve core; the installation shaft is coaxially arranged with the valve stem; a valve seat is provided on the valve body; and the valve core includes a sealing surface that cooperates with the valve seat for sealing.

[0006] By using the above technical solution, the arc-shaped valve core, that is, the opening and closing element, can reduce material consumption and weight compared to the spherical valve core, while still achieving the valve opening and closing effect. The sealing surface can also play a sealing role.

[0007] Optionally, the valve body includes a first connecting end and a second connecting end; the first connecting end and the second connecting end are connected to an external flange; the valve body is also provided with an open end; a circular cover plate is connected to the flange on the open end.

[0008] With the above technical solution, the first and second connecting ends are existing technologies with flange connections. They are connected through external pipes and equipment flanges. The cover plate allows for operation inside the valve body, such as observation and maintenance.

[0009] Optionally, a plurality of filter rods are provided on the mounting shaft; the filter rods are evenly distributed along the axis of the mounting shaft; a mounting ring is provided in the middle of the filter rod; a limiting notch is provided below the inner ring of the mounting ring; a limiting protrusion is provided on the mounting shaft to cooperate with the limiting notch; the limiting protrusion limits the circumferential movement of the mounting ring to prevent the mounting ring from rotating.

[0010] With the above technical solution, the filter rod can filter the fluid medium when the valve is open, and the filtered impurities can be removed when the cover is opened; the upper limit notch of the mounting ring allows the filter rod to rotate. When the filter rod needs to rotate, the mounting ring can be moved upward to disengage the limit protrusion from the limit notch, thus avoiding the limit and enabling rotation.

[0011] Optionally, the sealing surface of the valve core is circular; the valve core also includes two arc-shaped plates; one end of the arc-shaped plate is connected to the valve shaft, and the other end is integrally connected to the sealing surface; an annular notch is provided at the edge of the sealing surface; an annular receiving groove is provided at the edge of the annular notch; an annular sealing strip is provided in the receiving groove; a limiting strip is installed on the annular notch by screws to fix the sealing strip; the sealing strip has a gourd-shaped cross-section, with a first end and a second end; the volume of the first end is smaller than that of the second end; the first end passes through the gap between the limiting strip and the annular notch and elastically abuts against the valve body.

[0012] With the above technical solution, the sealing strip can be replaced, which facilitates maintenance and improves the product's service life. The first and second ends have a gourd-shaped structure, which facilitates the fixing and limiting of the sealing strip by the limiting strip.

[0013] Optionally, the valve seat includes a retaining ring disposed on the inner wall of the first connecting end and the second connecting end; the retaining ring is provided with a plurality of threaded holes; a sealing ring is provided on one side of the retaining ring; the sealing ring has an inclined surface; the inclined surface abuts against the first end; and a screw is provided on the retaining ring, passing through the threaded holes and threadedly fixedly connected to the sealing ring.

[0014] The above technical solution, with its fixed ring, facilitates the fixing of the sealing ring, as well as its disassembly and replacement, thus simplifying maintenance and extending the product's lifespan.

[0015] The beneficial effects of this application are as follows: Compared with the prior art, the portable ball valve with filtering function provided by this application has the advantages of lightweight structure, convenient parts replacement and long service life. Attached Figure Description
