Description

Technical Field

[0001] This utility model relates to the technical field of three-way ball valves, and in particular to a three-way ball valve for water pipes. Background Technology

[0002] A three-way ball valve is a fluid control valve used for switching, diverting, or merging flows. The valve body has a ball-shaped closing element and three channels (L-type or T-type). By rotating the ball, the fluid flow direction can be changed, realizing the connection or isolation between different pipelines. It is widely used in industries such as petroleum, chemical, and water treatment. It features a compact structure, good sealing performance, and convenient operation. As the use of three-way valves becomes more widespread, the requirements for three-way valves are also becoming more stringent. Therefore, there is a particular need for a three-way ball valve for water pipes.

[0003] However, while the existing three-way ball valves for water pipes can achieve precise control of water flow through simple parts, the filter screen of the filter assembly is not only cumbersome to clean, but also relies on the hinge structure of the cleaning pipe, which is prone to wear after long-term use. Furthermore, the device lacks an emergency shut-off component when the ball valve is damaged, thus affecting normal use.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN111365489A disclosing a three-way ball valve. The patent describes a valve comprising a three-way pipe, an inlet pipe, a first outlet pipe, a second outlet pipe, a transmission assembly, a rotating assembly, and a filter assembly. The inlet pipe is located at the inlet end of the three-way pipe and is connected to it. The first outlet pipe is located at one outlet end of the three-way pipe, and the second outlet pipe is located at the other outlet end of the three-way pipe and is connected to it. The three-way pipe contains an installation cavity, within which a three-way ball is rotatably fitted. The transmission assembly is located at the top of the three-way pipe. The rotating assembly is mounted on the transmission assembly, and the filtering assembly is mounted on the inlet pipe, with the filtering assembly slidingly engaged with the inlet pipe. This invention, through the high precision of the gears and accurate transmission, can precisely control the rotation of the three-way ball valve within its mounting cavity, thus precisely controlling the water flowing through the three-way ball valve. However, although the above device achieves precise water control within the three-way ball valve through simple component assembly, cleaning the filter screen of its filtering assembly is not only cumbersome but also relies on the hinged structure of the cleaning pipe, making it prone to wear over long-term use. Furthermore, the device lacks an emergency shut-off component when the ball valve fails, thus affecting normal operation.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this utility model is to provide a three-way ball valve for water pipes to solve the problems mentioned in the background art. Although the above-mentioned device achieves precise control of water in the three-way ball valve through simple parts, the filter screen of its filter assembly is not only cumbersome to clean, but also relies on the hinge structure of the cleaning pipe, which is prone to wear after long-term use. Furthermore, when the ball valve is damaged, the device lacks an emergency shut-off component, thus affecting normal use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a three-way ball valve for water pipes, comprising a valve body and a combination mechanism, wherein the combination mechanism is provided on one side of the surface of the valve body;

[0008] The combined mechanism includes a connecting pipe, a threaded groove, a recess, an extension pipe, a sealing ring, a flange, a mounting frame, a closing plate, an internal thread, a connecting block, a filter screen, and a knob. The valve body is connected to the connecting pipe in three directions. A threaded groove is formed on the other side of the connecting pipe. A recess is formed on the inner wall of the connecting pipe. An extension pipe is connected to the side wall of the connecting pipe. A sealing ring is installed along the edge of the connecting pipe. A flange is connected to the internal thread of the threaded groove. A mounting frame or a closing plate is fitted inside the recess. An internal thread is formed on the inner wall of the extension pipe. A connecting block is connected to the other side of both the mounting frame and the closing plate. A filter screen is installed inside the mounting frame. A knob is fitted to the other side of the connecting block.

[0009] Preferably, a sealing ring is also installed at the inner edge of the flange, and a sealing ring is also installed at the edge of the extension pipe. The size of the sealing ring on the extension pipe or the flange is different.

[0010] Preferably, the groove is aligned with the position of the extension tube, and the surface of the connecting block is fitted inside the extension tube.

[0011] Preferably, the knob is threaded into an internal thread, and the knob is tightly connected to the outer tube by a sealing ring.

[0012] Preferably, the other side of the connecting block is fitted inside the knob, and the connecting block and the knob form a mutually rotating structure.

[0013] Preferably, the filter screen matches the inner diameter of the connecting pipe, and the closing plate matches the pipe diameter of the connecting pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides a technical solution: a three-way ball valve for water pipes, comprising a valve body 1 and a combination mechanism 2, wherein the combination mechanism 2 is provided on one side of the surface of the valve body 1;

[0024] The assembly 2 includes a connecting pipe 201, a threaded groove 202, a recess 203, an extension pipe 204, a sealing ring 205, a flange 206, a mounting frame 207, a closing plate 208, an internal thread 209, a connecting block 210, a filter screen 211, and a knob 212. The valve body 1 is connected to the connecting pipe 201 in three directions. A threaded groove 202 is provided on the other side of the connecting pipe 201. A recess 203 is provided on the inner wall of the connecting pipe 201. The side wall of the connecting pipe 201 is connected to... An extension tube 204 and a connecting tube 201 are fitted with a sealing ring 205 along their edges. A flange 206 is threaded into the internal thread of the threaded groove 202. A mounting frame 207 or a closing plate 208 is fitted inside the groove 203. An internal thread 209 is formed on the inner wall of the extension tube 204. A connecting block 210 is connected to the other side of both the mounting frame 207 and the closing plate 208. A filter screen 211 is installed inside the mounting frame 207. A knob 212 is fitted to the other side of the connecting block 210. The components 201 (connecting pipe), 202 (threaded groove), 203 (groove), 204 (extension pipe), 205 (sealing ring), 206 (flange), 207 (mounting frame), 208 (closing plate), 209 (internal thread), 210 (connecting block), 211 (filter screen), and 212 are configured such that, during use, when the connection conditions of the valve body 1 are poor or a temporary connection is required, the flange 206 can be disassembled via the threaded groove 202 and a simple connection can be made via external connecting components. Subsequently, during the long-term operation of the valve body 1, impurities will appear in the water. By pre-setting the filter screen 211, simple filtration of impurities can be performed, thereby improving the service life of the sealing components in the valve body 1. At the same time, when it is necessary to clean the filter screen 211 or disassemble the closing plate 208, the knob 212 is turned. The rotation of the knob 212 on the internal thread 209 drives the connecting block 210 to move, thereby allowing the connecting block 210 to pull the mounting frame 207 or the closing plate 208 out of the groove 203 for quick replacement.

[0025] Furthermore, a sealing ring 205 is also installed at the inner edge of the flange 206 and at the edge of the extension pipe 204. The size of the sealing ring 205 on the extension pipe 204 or the flange 206 is different. Through the setting of the sealing ring 205, the sealing ring 205 plays a key role in the entire mechanism in preventing leakage, stabilizing the connection, compensating for gaps and adapting to structural changes, ensuring that all connecting parts in the valve can operate stably under different working conditions, effectively preventing fluid leakage, and improving sealing performance and service life.

[0026] Furthermore, the groove 203 and the extension tube 204 are aligned, and the surface of the connecting block 210 is fitted inside the extension tube 204. Through the setting of the extension tube 204, the connecting block 210 is fitted inside the extension tube 204 and connected to the mounting frame 207 or the closing plate 208 through a sliding structure, so that the mounting frame 207 or the closing plate 208 can be flexibly adjusted in position. This sliding structure facilitates quick replacement of the filter screen 211 (filtration mode) or the closing plate 208 (closed mode), improving the convenience and adaptability of operation.

[0027] Furthermore, the knob 212 is threaded into the internal thread 209. The knob 212 is tightly connected to the extension tube 204 through the sealing ring 205. By setting the knob 212, the knob 212 is threaded into the internal thread 209 of the extension tube 204. By rotating, the position of the connecting block 210 can be adjusted, thereby controlling the opening and closing state of the mounting frame 207 (with filter screen 211) or the closing plate 208. When the knob 212 is tightened, the connecting block 210 can be securely fitted inside the extension tube 204, ensuring that the mounting frame 207 or the closing plate 208 will not loosen or shift. When the knob 212 is loosened, the filter screen 211 or the closing plate 208 can be easily disassembled or replaced, which is convenient for maintenance and cleaning.

[0028] Furthermore, the other side of the connecting block 210 is fitted inside the knob 212, and the connecting block 210 and the knob 212 form a mutually rotating structure. Through the setting of the connecting block 210, one side of the connecting block 210 is connected to the mounting frame 207 or the closing plate 208, and the other side is fitted inside the knob 212, so that the mounting frame 207 or the closing plate 208 can be stably fixed in the groove 203 of the connecting pipe 201. Through the connecting block 210, the mounting frame 207 (with filter screen 211) or the closing plate 208 can be quickly replaced to adapt to different working requirements (filtration or closed fluid).

[0029] Furthermore, the filter screen 211 matches the inner diameter of the connecting pipe 201, and the closing plate 208 matches the pipe diameter of the connecting pipe 201. With the filter screen 211 installed inside the mounting frame 207, it is used to intercept solid particles, impurities, or sediments in the fluid, effectively extending the service life of the components in the valve body 1. At the same time, the size of the filter screen 211 matches the inner diameter of the connecting pipe 201, allowing it to be firmly fixed inside the pipe and not to fall off or shift due to fluid pressure or vibration.

[0030] Furthermore, the threaded groove 202 is located on the outside of the sealing ring 205. The flange 206 is tightly connected to the connecting pipe 201 through the sealing ring 205. With the threaded groove 202, the internal threaded structure is used for threaded connection with the flange 206, ensuring that the flange 206 can be firmly fixed to the connecting pipe 201. Through the threaded connection, the flange 206 can be easily disassembled or installed, improving the convenience of maintenance.

[0031] Furthermore, the mounting frame 207 and the closing plate 208 form a sliding structure with the groove 203 and the extension pipe 204 via the connecting block 210. With the mounting frame 207 and the closing plate 208, a filter screen 211 is installed inside the mounting frame 207 to fix the filter screen 211 and keep it stable so that it will not shift or deform during the filtration process. With the support of the mounting frame 207, the filter screen 211 can be evenly stressed, improving the filtration efficiency and preventing damage caused by fluid impact. When the third-direction connecting pipe 201 does not require fluid flow, the closing plate 208 can replace the mounting frame 207 (filter screen 211) to completely block the passage of the connecting pipe 201 and realize the sealing and closing function. This is suitable for situations where the valve is closed, under maintenance, or the fluid delivery is stopped.

[0032] Working principle: When the connection conditions of the valve body 1 are poor or a temporary connection is required, the flange 206 is disassembled through the threaded groove 202 and a simple connection is made through the external connection component. Subsequently, during the long-term operation of the valve body 1, impurities will appear in the water. By setting the filter screen 211 in advance, the impurities are simply filtered, thereby improving the service life of the sealing components in the valve body 1. At the same time, when it is necessary to clean the filter screen 211 or remove the closing plate 208, the knob 212 is turned. The rotation of the knob 212 on the internal thread 209 drives the connecting block 210 to move, so that the connecting block 210 can drive the mounting frame 207 or the closing plate 208 to be pulled out of the groove 203 for quick replacement.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
