Description

Technical Field

[0001] This utility model relates to the technical field of three-way ball valve devices, specifically a three-way ball valve. Background Technology

[0002] A three-way ball valve is a valve that controls the flow direction of fluid or splits / combines flow by rotating a ball. It is widely used in industries such as petroleum, chemical, power, and pharmaceutical. Its core feature is that it has three channels (one inlet and two outlets or two inlets and one outlet), which can realize the function of switching, distributing or mixing the flow direction of the medium. Some three-way ball valves can also be electrically driven.

[0003] The prior art patent document CN205745455U discloses an electric three-way ball valve, including a valve body with three channels communicating with a valve cavity. A valve seat is installed inside the valve cavity, and a valve core is rotatably installed inside the valve seat. A valve stem is installed on the upper end of the valve core, and the upper end of the valve stem is driven by an electric actuator installed on the upper end of the valve body. A packing seal structure is provided between the valve stem and the valve body mounting hole. A valve core fixing seat is provided on the lower end face of the valve body, and a fixing shaft is provided on the upper end face of the fixing seat. A shaft head is provided on the upper end of the fixing shaft, and the upper end of the shaft head is inserted into a rotating mounting groove on the valve core. A wear-resistant bushing is fitted on the shaft head. The main body of the wear-resistant bushing is an inverted barrel shape, and an integrally formed tray is provided on the outer wall of the wear-resistant bushing. The upper end face of the tray has a spherical surface that mates with the outer wall of the valve core. This utility model has a reasonable structural design. By installing a wear-resistant bushing, tray, and sleeve on the fixing shaft, the wear resistance of the fixing shaft and the stability of the valve core during rotation can be improved.

[0004] Although this device offers many benefits, it still suffers from the following problems: If the device experiences a sudden power outage during use, the internal electrically driven components will immediately lock up, rendering the direction of the diverted flow or the valve closing function unusable, severely impacting operational convenience. Furthermore, due to the lack of external protective structures on the valve body, the device may be damaged and rendered unusable upon impact. In addition, the lack of a filter at the pipe connection points allows impurities to enter the valve body during fluid diversion or merging. Over time, these impurities can easily clog the valve body, affecting the normal operation of the system and resulting in poor filtration. Moreover, the device cannot be installed on water pipes with incompatible diameters, leading to poor applicability. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues—that the internal electrically driven components of the device immediately lock up in the event of a sudden power outage, rendering the flow direction or valve closure function unusable, and that the lack of external protective structure on the valve body makes it susceptible to damage from impacts, severely impacting operational convenience—and the absence of a filter at pipe connections, allowing impurities to enter the valve body during fluid diversion or merging, which can clog the valve body over time, affecting system operation, resulting in poor filtration, and the inability to accommodate pipes with incompatible diameters, thus limiting its applicability—this is a significant concern.

[0008] Therefore, the purpose of this utility model is to provide a three-way ball valve with a butterfly valve inside the valve body that can change the direction of water flow or close the valve by rotating a disc. In the event of a sudden power failure, the water flow direction can be changed or the valve can be closed by manually rotating the disc, which is convenient. At the same time, a filter screen is fixedly connected inside the connecting pipe. When the water flows through the filter screen, the impurities inside will be filtered out. Since the connecting pipe is connected by a threaded pipe, the filter screen can be replaced when it becomes clogged due to excessive impurities. The filtration effect is good.

[0014] In a preferred embodiment of the three-way ball valve of this utility model, a connecting ring is fixedly connected to the side wall of the valve body. The outer circumference of the connecting ring fits into the valve head hole. The connecting part of the ball valve can be protruded through the valve head hole, which also facilitates the replacement of the filter screen.

[0015] In a preferred embodiment of the three-way ball valve of this utility model, a positioning valve head is fixedly connected to the front of the connecting ring, and a connecting bolt is threadedly connected to the inside of the positioning valve head, so that the connecting valve head can be fixed by the positioning valve head.

[0016] In a preferred embodiment of the three-way ball valve of this utility model, the outer circumferential wall of the connecting bolt is threaded to the connecting valve head, and the back of the connecting valve head is fixedly connected to the positioning valve head.

[0017] In a preferred embodiment of the three-way ball valve of this utility model, the top and bottom of the valve body are fixedly connected to the positioning rod, the top of the positioning rod is fixedly connected to the top plate, and the bottom of the positioning rod is fixedly connected to the bottom plate.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This type of three-way ball valve features positioning rods fixedly connected to the top and bottom of the valve body. These positioning rods are connected to a top plate and a bottom plate, respectively. The top and bottom plates, along with the side baffles and side arc plates, enhance the device's protective performance and prevent deformation of the valve body. Simultaneously, a butterfly valve is connected to the top of the top plate via a rotating shaft.

This allows for operation and control of the ball valve even during power outages, providing good protection, ease of operation, and emergency response.

[0021] This type of three-way ball valve features a filter screen fixed inside the connecting pipe. The connecting pipe is threaded into the first connecting flange, which is also connected to the front of the valve head. The second connecting flange is used to connect to the water pipe. As water flows through the connecting pipe, impurities mixed inside are filtered by the filter screen, preventing them from entering the ball valve. When connecting to a smaller diameter water pipe, the clamping screw can be turned to clamp the smaller diameter pipe. This allows the valve to be used with water pipes of different diameters. The connecting pipe can also be replaced to ensure the filtration effect of the filter screen. Attached Figure Description

[0034] This utility model provides an overall structural diagram of a three-way ball valve embodiment, including:

[0035] Please see Figures 1-5This embodiment of a three-way ball valve includes a valve body 1. A first fixing plate 8 is welded to the top of the valve body 1. A through hole 9 is opened on the top of the first fixing plate 8. A rotating rod 17 is threadedly connected to the inner circumference of the through hole 9. A butterfly valve 19 is welded to the outer circumference of the rotating rod 17. The butterfly valve 19 is made of aluminum alloy. Through the valve plate of the butterfly valve 19, it can guide water flow or directly close the internal channel of the valve body 1, making operation relatively convenient. The rotating rod 17 is rotatably connected to the top plate 21 through a damping shaft. A side baffle 25 is welded to the bottom of the top plate 21. A side arc plate 26 is welded to the side of the side baffle 25. The side baffle 25 and the side arc plate 26 are also made of aluminum alloy. In this way, when the valve body 1 is impacted, the... The side arc plate 26 and the side baffle 25 protect the valve body 1 and prevent deformation of the valve body 1. The front of the side baffle 25 is provided with a valve head hole 24. The part of the water pipe can be extended out of the side baffle 25 through the valve head hole 24, which facilitates the connection of the water pipe and the replacement of the filter screen 27. The bottom of the side baffle 25 and the side arc plate 26 is welded with a base plate 22. The bottom plate 22 and the top plate 21 are welded with a positioning rod 23. The top of the rotating rod 17 is welded with a main rod 18. The outer circumference of the main rod 18 is welded with a rotating disk 20. By rotating the rotating disk 20, the main rod 18 and the rotating rod 17 can be directly rotated, thereby driving the butterfly valve 19 to guide the direction or close the valve. Manual operation does not require electric drive, which is convenient for emergency and emergency use.

[0036] It is worth noting that, to facilitate the replacement of the filter screen 27, specifically, a connecting ring 4 is fitted to the inner circumference of the valve head hole 24. The front of the connecting ring 4 is connected to a connecting valve head 6 via a positioning valve head 5. Multiple connecting holes 10 are provided on the front of the connecting valve head 6. Flange bolts 11 are threaded into the interior of the connecting holes 10. A first connecting flange 12 is threaded into the outer circumference of the flange bolts 11. The first connecting flange 12 can be installed on the front of the connecting valve head 6 through the mutual cooperation of the flange bolts 11, facilitating installation and replacement. A threaded pipe 13 is threaded into the inner circumference of the first connecting flange 12. A connecting pipe 14 is welded to the front of the threaded pipe 13. A filter screen 27 is welded into the inner circumference of the connecting pipe 14. The filter screen 27 welded inside the connecting pipe 14 can filter out impurities mixed in the water. Simultaneously, a threaded pipe 13 is welded to the bottom of the connecting pipe 14, which can also facilitate... The connecting pipe 14 can be easily replaced or installed. The inner circumference of the connecting pipe 14 is connected to a second connecting flange 15 by threads. Multiple positioning bolts 16 are connected to the inside of the second connecting flange 15 by threads. A sealing ring 32 is fixedly connected to the inside of the second connecting flange 15. A second fixing block 28 is fixedly connected to the front of the second connecting flange 15. A clamping screw 29 is connected to the inside of the second fixing block 28 by threads. The bottom end of the clamping screw 29 is connected to a clamping plate 30 by a rotating shaft. An anti-slip plate 31 is fixedly connected to the inside of the clamping plate 30. The anti-slip plate is made of rubber. By first attaching the anti-slip plate 31 to the outer circumference of the external water pipe, the friction between the water pipe and the clamping plate 30 is enhanced to prevent the water pipe from slipping. When installing the external water pipe, the clamping screw 29 can be turned so that the clamping plate 30 can clamp the connected water pipe. This device can be connected to water pipes of various specifications and has good applicability.

[0037] Next, in order to facilitate the installation of the valve body 1 in the required position, specifically, the bottom of the valve body 1 extends through the base plate 22, and a valve seat 2 is welded to the bottom of the valve body 1. The valve seat 2 has multiple positioning holes 3 inside. By cooperating with the positioning holes 3 and the valve seat 2, the entire valve body 1 can be fixedly connected to the required position by bolts.

[0038] Meanwhile, to facilitate the positioning of the connecting ring 4, specifically, the valve body 1 is welded with a connecting ring 4 on its side wall, and the outer circumferential wall of the connecting ring 4 fits against the valve head hole 24.

[0039] Furthermore, to facilitate the installation of the water pipe and the first connecting flange 12, specifically, a positioning valve head 5 is welded to the front of the connecting ring 4, and a connecting bolt 7 is threadedly connected inside the positioning valve head 5.

[0040] It is worth noting that, in order to prevent the connecting valve head 6 from being rotated during connection, the outer circumference of the connecting bolt 7 is connected to the connecting valve head 6 by thread, and the positioning valve head 5 is welded to the back of the connecting valve head 6.

[0041] Finally, in order to strengthen the stability between the valve body 1 and the top plate 21 and the bottom plate 22, specifically, a positioning rod 23 is welded to the top and bottom of the valve body 1, the top plate 21 is welded to the top of the positioning rod 23, and the bottom plate 22 is welded to the bottom of the positioning rod 23.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Combination Figures 1-5 The specific usage process of a three-way ball valve according to this embodiment is as follows:

[0044] 1. When using this type of three-way ball valve, the required pipe needs to be installed on the front of the connecting valve head 6 first. The first connecting flange 12 is installed on the front of the connecting valve head 6 by screwing the flange bolt 11 inside the connecting hole 10. Then, the connecting pipe 14 is screwed into the inner circumference of the first connecting flange 12 through the threaded pipe 13. Next, the second connecting flange 15 is screwed into the inner circumference of the connecting pipe 14 in the same way. The water pipe to be connected is connected through the positioning bolt 16 inside the second connecting flange 15. When encountering a water pipe with a smaller diameter, the clamping screw 29 can be turned during the connection process to make the clamping plate 30 continuously shrink and finally clamp the water pipe with a smaller diameter. Then, the sealing ring 32 is glued and fixed on the inner circumference of the second connecting flange 15, so that the device can be equipped with external water pipes of various diameters.

[0045] 2: After the connection is completed, it can be put into use. During use, the filter screen 27 inside the connecting pipe 14 will continuously filter out impurities mixed in the water, blocking the impurities outside the filter screen 27 and preventing them from entering the valve body 1 and clogging the valve body 1. At the same time, since the connecting pipe 14 is connected through the threaded pipe 13, impurities will also clog the filter screen 27 after a long period of filtration. At this time, the flange bolt 11 can be removed, and the connecting pipe 14 together with the threaded pipe 13 can be unscrewed from the first connecting flange 12 to clean or replace the filter screen 27, thereby maintaining the filtration effect of the device.

[0046] 3. During the operation of this device, a sudden power outage may occur, causing the internal electrically driven components to lock up. This would prevent valve body 1 from performing flow diversion or valve closure operations. In this case, the operator can manually rotate the rotating disc 20. The rotating disc 20 will drive the main rod 18 and the rotating rod 17 to rotate. The rotation of the rotating rod 17 will drive the butterfly valve 19 to adjust its position, thus allowing manual flow diversion or direct valve closure operations. At the same time, a top plate 21 is rotatably connected to the outer circumference of the rotating rod 17. A side baffle 25 and a side arc plate 26 are fixedly connected to the bottom of the top plate 21. Through the protective performance of the side baffle 25 and the side arc plate 26, the valve body 1 can be prevented from being damaged or deformed by impact, which would cause problems with the closure or flow diversion of valve body 1 and prevent the butterfly valve 19 from rotating freely due to deformation. The protection effect is good.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
