Description

Technical Field

[0001] This utility model belongs to the field of valve technology and relates to an on / off ball valve with a filter structure. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve axis. It can also be used for fluid regulation and control. Among them, the hard-seal V-type ball valve has a strong shearing force between the V-shaped ball core and the metal valve seat with hard alloy overlay, making it particularly suitable for media containing fibers, small solid particles, etc. Multi-port ball valves can not only flexibly control the merging, splitting, and switching of the flow direction of the media in pipelines, but also close any channel while connecting the other two channels.

[0003] Existing ball valves typically cannot filter the water flowing inside during use, allowing impurities to enter directly. Over time, these impurities accumulate inside the ball valve, causing blockages and rendering it unusable, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing an on / off ball valve with a filter structure that is easy to install and disassemble.

[0005] The objective of this utility model can be achieved through the following technical solution: A ball valve with a filter structure, comprising a ball valve body, a valve ball disposed within the ball valve body, and a valve stem connected to the valve ball for controlling its rotation; the ball valve body has a flow pipe for liquid flow; characterized in that a filter assembly for filtering impurities is disposed within the ball valve body; a fixing part for installing and fixing the filter assembly is fixedly disposed on the ball valve body; the fixing part has a transverse groove, which is connected to the flow pipe inside the ball valve body and allows for the installation of the filter assembly; the filter assembly is made of a fixed... The valve body comprises a fixed frame, a connecting frame, and a filter screen. The connecting frame has a water passage hole for water to pass through, and the filter screen is located at the water passage hole. The fixed frame has a positioning rod, and the fixed part has a slot for the positioning rod to extend into. The fixed part has a positioning component that cooperates with the positioning rod. The positioning component consists of a positioning element and a return spring. The fixed part has an installation slot for installing the positioning component, and the positioning rod has a positioning hole that matches the positioning element. The return spring causes the positioning rod to retract at the installation slot, thereby fixing the filter component to the ball valve body.

[0006] In the aforementioned ball valve with a filter structure, the reset spring is disposed in the mounting groove and sleeved on the positioning rod. One end of the positioning rod extends out of the mounting groove and engages with the opening of the positioning rod, while the other end of the positioning rod extends out of the fixing part and is connected to a pull rod.

[0007] In the aforementioned ball valve with a filter structure, there are two positioning components, located on the left and right sides of the fixed part, respectively.

[0008] In the aforementioned ball valve with a filter structure, the diameter of the water passage hole is smaller than the diameter of the flow pipe, and the filter screen on the water passage hole is used to filter impurities in the flow pipe.

[0009] In the aforementioned ball valve with a filter structure, a sealing ring for enhancing the seal is provided between the connecting frame and the ball valve body.

[0010] Compared with existing technologies, this ball valve with a filter structure uses a positioning component to fix the filter component inside the ball valve body, filtering out impurities from the liquid entering the valve ball and improving the service life of the ball valve.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 , Figure 2As shown, this ball valve with a filter structure includes a ball valve body 1, a valve ball inside the ball valve body 1, and a valve stem connected to the valve ball to control its rotation. The ball valve body 1 has a flow pipe 2 for liquid flow, and a filter assembly 3 for filtering impurities is installed inside the ball valve body 1. A fixing part 4 is fixedly installed on the ball valve body 1 for installing and fixing the filter assembly 3. The fixing part 4 has a horizontal groove that communicates with the flow pipe 2 inside the ball valve body 1 and allows for the installation of the filter assembly 3. The filter assembly 3 consists of a fixing frame 5, a connecting frame 6, and a filter screen 7. The connecting frame 6 has a water passage hole for water passage, and the filter screen 7 is located at the water passage hole. The fixing frame 5 is provided with a positioning rod 8. The fixing part 4 has a slot for the positioning rod 8 to extend into. The fixing part 4 is provided with a positioning component 9 that cooperates with the positioning rod 8. The positioning component 9 consists of a positioning element 10 and a return spring 11. The fixing part 4 has an installation slot for the positioning component 9 to be installed. The positioning rod 8 has a positioning hole that matches the positioning element 10. The positioning rod 8 retracts at the installation slot by the action of the return spring 11, thereby fixing the filter component 3 to the ball valve body 1.

[0016] To elaborate further, when the filter assembly 3 needs to be installed, first pull the lever 12 of the positioning assembly 9 to retract the positioning piece 10 into the mounting groove, compress the return spring 11, then match the fixing bracket 5 with the transverse groove, and extend the connecting bracket 6 into the ball valve body 1. The filter screen 7 is located at the flow pipe 2 of the ball valve body 1. Release the lever 12, the return spring 11 rebounds, and the positioning piece 10 extends out of the mounting groove again and matches the positioning hole of the positioning rod 8, thereby fixing the filter assembly 3 to the ball valve body 1. When the filter assembly 3 needs to be disassembled, pull the lever 12 again to retract the positioning piece 10 into the mounting groove, compress the return spring 11, release the positioning of the positioning piece 10 and the positioning rod 8, and the filter assembly 3 can be removed from the ball valve body 1.

[0017] To elaborate further, the reset spring 11 is set in the mounting groove and sleeved on the positioning rod 8. One end of the positioning rod 8 extends out of the mounting groove and cooperates with the opening of the positioning rod 8. The other end of the positioning rod 8 extends out of the fixing part 4 and is connected to the pull rod 12.

[0018] To elaborate further, there are two positioning components 9, located on the left and right sides of the fixing part 4, respectively. The two positioning components 9 are used to fix the left and right sides of the filter assembly 3, making the filter assembly 3 more stable during installation.

[0019] To elaborate further, the diameter of the water passage hole is smaller than the diameter of the flow pipe 2, and the filter screen 7 on the water passage hole is used to filter out impurities in the flow pipe 2.

[0020] To elaborate further, a sealing ring is provided between the connecting bracket 6 and the ball valve body 1 to enhance the seal.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
