Description

Technical Field

[0001] This utility model relates to the field of water technology, and in particular to a filter ball valve. Background Technology

[0002] When transporting liquids through pipelines, the flow of liquid needs to be controlled by switching valves on and off according to actual needs. However, liquids often contain solid impurities, which not only affect equipment using the liquid and reduce its service life, but also clog valves over time. To solve this problem, a filter ball valve has been proposed. This filter ball valve can filter larger particles in the liquid through a filter screen, thereby improving the quality of the liquid exiting the pipeline. However, existing filter ball valves require regular cleaning of the filter screen, and the disassembly and assembly of the filter screen is inconvenient, which is detrimental to later maintenance.

[0003] In addition, existing filter ball valves have limited internal space, making it easy for impurities to accumulate inside the filter screen, causing filter screen blockage. This not only affects the filtration effect but also easily leads to a reduction in flow rate, requiring frequent cleaning of the filter ball valve. Utility Model Content

[0004] The present invention provides a filter ball valve that can solve the problem of inconvenient disassembly and assembly of filter screens, thereby improving the disassembly and assembly speed of filter screens.

[0005] To achieve this objective, the present invention adopts the following technical solution: A filter ball valve includes a valve body, a valve stem, a valve ball, a filter screen unit, and a sealing seat. The valve ball is installed in the valve body and has a filter chamber inside. One end of the valve stem passes through the valve body and is connected to the valve ball. The end of the valve ball opposite to the valve stem has an installation hole communicating with the filter chamber. The valve body has an assembly port that communicates with the filter chamber through the installation hole. The filter screen unit is fixedly installed in the filter chamber circumferentially from the assembly port. The sealing seat is detachably inserted into the assembly port and supported by the filter screen unit.

[0006] In the recommended embodiment, a receiving cavity is formed within the sealing seat, which communicates with the filter chamber. This receiving cavity is used to contain impurities, preventing their accumulation within the filter chamber and negatively impacting the flow rate, thereby reducing the frequency of cleaning the filter ball valve.

[0007] In the recommended embodiment, the sealing seat includes a surrounding wall and a base plate. One end of the surrounding wall is fixed to the base plate. The space enclosed by the surrounding wall and the base plate forms a receiving cavity, which communicates with the filter cavity and is located directly below the filter cavity. Impurities in the filter cavity can fall directly into the receiving cavity, enabling automatic collection of impurities.

[0008] In the recommended embodiment, the assembly port is provided with an insertion hole that penetrates the inner wall of the assembly port; the outer side of the enclosure is provided with a limiting part; the filter ball valve also includes a pin, which passes through the insertion hole and is simultaneously limited by the limiting part. The insertion hole, the limiting part, and the pin cooperate with each other to limit the sealing seat and prevent the sealing seat from coming out of the assembly port.

[0009] In the recommended embodiment, the limiting part is a limiting groove, and the pin passes through the insertion hole and is simultaneously limited within the limiting groove. Using a limiting groove for the limiting part not only facilitates processing but also ensures high stability.

[0010] In the recommended embodiment, the assembly port is provided with a pair of insertion holes, and the limiting groove surrounds the enclosure wall; the pin is a U-shaped pin, which includes a connecting rod and a first pin and a second pin respectively fixed to both ends of the connecting rod. The first pin and the second pin are respectively inserted into the corresponding insertion holes and simultaneously limited within the limiting groove. The use of a U-shaped pin provides high structural stability for the limiting mechanism.

[0011] In the recommended embodiment, the outer edge of the base plate is provided with a protruding stop, and the connecting rod is limited by the stop. The stop can limit the connecting rod and prevent the U-shaped pin from rotating.

[0012] In the recommended embodiment, the filter unit is circumferentially fixed to the sealing seat. This embodiment cleverly uses the sealing seat to circumferentially fix the filter unit, preventing rotation of the filter unit.

[0013] In the recommended embodiment, the filter unit includes a frame and a filter screen that are fixed to each other, the frame having a protrusion; and the top surface of the enclosure having a recess that mates with the protrusion.

[0014] In the recommended embodiment, the filter screen includes a circular portion and a semi-circular portion that are fixed to each other. A notch is formed on the opposite side of the semi-circular portion, and this notch is positioned opposite the inlet / outlet of the filter ball valve. The filter screen's design, with its circular and semi-circular portions, not only allows for thorough filtration of the fluid but also improves filtration efficiency due to the large area of ​​its notches.

[0015] The beneficial effects of this utility model are: The sealing seat of this utility model is connected to the assembly port of the valve body by plugging in. When cleaning, first pull the sealing seat out of the assembly port, and then remove the filter screen unit for cleaning. No tools are needed for disassembly and assembly, which can significantly improve the efficiency of disassembly and assembly.

[0016] The filter unit is circumferentially fixed, which prevents the filter unit from rotating during operation, thus ensuring the filtration effect. Attached Figure Description
