Description

Technical Field

[0001] The utility model relates to a fully welded Y-type filtering ball valve, belonging to the technical field of valves. Background Art

[0002] A ball valve is a valve device used to control the flow of fluids in a pipeline and is widely used in pipelines. It consists of a valve body and a housing. A Y-type strainer is installed in pipelines to filter impurities. The Y-type strainer's housing is divided into two chambers by a partition plate. The partition plate is provided with a fluid passageway, and a filter chamber is located in the corresponding fluid passageway. The filter chamber houses a filter screen. The filter screen edge of the Y-type strainer can be disassembled, cleaned, and replaced, making it a common feature in pipelines. The ball valve and Y-type strainer are used together in pipelines. During pipeline construction, both need to be installed separately, which takes a long time. Integrating the two could shorten installation time. However, due to the large number of raw pipe sections involved, traditional mold processing is not suitable. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] The utility model is a fully welded Y-type filter ball valve, which is manufactured by combining a Y-type filter and a ball valve and adopting a welding process.

[0020] The device includes a ball valve and a Y-type strainer, which are connected and combined by welding. Generally, the housing of the ball valve and the housing of the Y-type strainer are made of carbon steel, which is easy to weld.

[0021] As shown in Figure 1, the ball valve primarily comprises pipe segment 1, pipe segment 2, and a valve cavity 3. Pipe segments 1 and 2 are located on opposite sides of the valve cavity 3. These segments, along with the valve cavity 3, generally form a circular tubular structure, with the valve cavity 3 having a larger diameter than the two segments. One end of each segment extends into the valve cavity 3, where it tapers to a narrower, more closed end that meets the two segments. The connection is then sealed by welding.

[0022] A spherical valve body 4 is disposed within the valve cavity 3, providing on-off control for the ball valve. The spherical valve body 4 is provided with a hole for fluid passage, and its surface mates with the inner end surfaces of pipe segments 1 and 2, as well as the inner surface of the valve cavity 3.

[0023] A Y-type filter is connected to the other end of the second pipe section 2. Specifically, the other end of the second pipe section 2 is sealed and connected to the housing 6 of the Y-type filter by welding.

[0024] The Y-type filter has a structure similar to a Y shape as a whole. A liquid separator 5 is fixedly installed inside the shell 6 of the Y-type filter, and the inner cavity of the shell 6 is divided into a liquid inlet cavity 7 and a liquid outlet cavity 8 by the liquid separator 5. Among them, the liquid inlet cavity 7 is connected with the pipe section 2 2, and the liquid outlet cavity 8 is used to connect with the main pipeline. The filter screen 9 is set on one side of the liquid outlet cavity 8. The filter screen 9 is in the shape of a cylindrical cup. A liquid hole is provided on the liquid separator 5, and the cup mouth of the filter screen 9 is aligned with the liquid hole on the liquid separator 5. The filter screen 9 is installed in the filter cavity 10 and can be easily disassembled for cleaning.

[0025] In practice, an obliquely positioned filter chamber 10 is typically welded to the outer surface of the Y-type filter housing 6, directly connecting the filter chamber 10 to the liquid outlet chamber 8. The liquid inlet chamber 7 and the filter chamber 10 are located on either side of the separator plate 5. In other words, the separator plate 5 separates the liquid inlet chamber 7 from the filter chamber 10 and the liquid outlet chamber 8. Liquid flows from the liquid inlet chamber 7 into the filter chamber 10 for filtration before entering the liquid outlet chamber 8.

[0026] In order to achieve the sealing cooperation between pipe section 1 and pipe section 2 and spherical valve body 4, the utility model Figure 2As shown, a stopper is provided on the inner end surface of pipe section 1 and pipe section 2, and then a gasket 11, elastic gasket 12, adjustment sleeve 13 and sealing ring 14 are provided in the stopper from the outside to the inside. Furthermore, a sealing ring 15 is provided on the outer side of the sealing ring 14. The above structure realizes the sealing cooperation between the ball valve body 4 and pipe section 1 and pipe section 2. Figure 1 As shown, an arcuate surface is provided on the inner end face of the sealing ring 14 , and the arcuate surface can be matched with the spherical valve body 4 , thereby increasing the sealing contact surface between the sealing ring 14 and the spherical valve body 4 and ensuring the sealing effect.

[0027] The utility model further requires that a sealing groove be provided on the outer side of the sealing ring 14, and then the sealing ring 15 is installed in the sealing groove. After the sealing ring 14 is installed in the stopper, the sealing ring 15 can be squeezed and deformed with the inner wall of the stopper to achieve sealing.

[0028] In the open state, the fluid passes through the ball valve and then enters the Y-type filter through the liquid inlet chamber 7, and is filtered by the filter screen. The filter screen can be disassembled for cleaning or replacement.

[0029] The ball valve and Y-type filter are made of carbon steel and welded together, which shortens the processing time and ensures the function of the Y-type filter. At the same time, the inner diameter of the ball valve is increased. At the same time, the ball valve and Y-type filter are integrated, which saves construction time without affecting the flow rate.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
