Description

Technical Field

[0001] This utility model relates to the field of fluid control equipment technology, specifically to a valve. Background Technology

[0002] One of the functions of valves is to ensure the forward flow of fluid and prevent backflow. In this sense, valves can be understood as check valves. In dual-circuit redundant piping systems (for "1+1" redundancy), such as dual-circulation water pump piping, a check valve is typically installed on the outlet pipes of each of the two pumps. Thus, when the pump in pipe I is running and the pump in pipe II is not running, the inlet pressure on both sides of the check valve in pipe I is greater than the outlet pressure, causing the valve disc of the check valve in pipe I to open. At the same time, the outlet pressure on both sides of the check valve in pipe II is greater than the inlet pressure, causing the valve disc of the check valve in pipe II to close, preventing backflow in pipe II.

[0003] However, since two check valves need to be introduced into the dual circulation water pump pipeline, this not only increases the pipeline layout volume, but also increases the risk of pipeline leakage. Utility Model Content

[0004] The purpose of this utility model is to provide a valve.

[0005] According to one aspect of the present invention, a valve component is provided, comprising a base and a valve seat, wherein the base is fixedly connected to the valve seat;

[0006] The valve seat has two inlet ends on one side and the base has one outlet end on one side.

[0007] The matrix includes a cavity, the cavity is U-shaped, the two openings of the U-shape are respectively connected to one of the inlet ends, and the bottom of the U-shape is connected to the outlet end;

[0008] Two valve discs, corresponding to the inlet end, are provided between the valve seat and the cavity. Each valve disc is opened or closed by rotating it with the valve seat.

[0009] In some embodiments, two square communication ports are arranged at the connection between the base and the valve seat. The two first square communication ports of the base are the entrances to the cavity, and a valve disc is rotatably connected to each of the two second square communication ports of the valve seat.

[0010] The base has a first rectangular mounting structure including two first square connecting ports, and the valve seat has a second rectangular mounting structure including two second square connecting ports. The base and the valve seat are fixedly connected by the first rectangular mounting structure and the second rectangular mounting structure.

[0011] Each valve disc is circular and has a mounting portion on its upper part. Each mounting portion is pivotally connected to the valve seat through a rotating shaft in a second square communication port, forming two independent rotating pairs.

[0012] The outer periphery of the second square connection has a groove for placing a rubber ring, so as to form a sealed press with the first square connection.

[0013] In some embodiments, the substrate has a double inlet channel arranged in a square and a cylindrical outlet channel to form the cavity of an integral structure.

[0014] In some embodiments, a filter is arranged within the outlet end.

[0015] According to one example, the filter is a porous cylindrical structure, with the cylindrical opening of the filter facing the outlet side of the outlet end.

[0016] According to one example, the filter has a double-layer cylindrical structure, with the outer cylinder having a wire mesh structure and the inner cylinder having a porous structure.

[0017] The filter has a cylindrical opening facing the outlet side of the outlet end, and the inner cylinder has a circular hole at its bottom and a square hole on its wall.

[0018] In some embodiments, a sensor mounting base is also arranged on the substrate.

[0019] The substrate has a pressure sensor mounting base on its side and a temperature sensor mounting base on its bottom.

[0020] In some embodiments, when fluid flows in through one of the inlet ends, a valve corresponding to that inlet end opens, the fluid enters the cavity, and the fluid pressure within the cavity causes the other valve to remain closed.

[0021] In some embodiments, the valve is connected to an external dual-redundant piping system, with each inlet end connected to one of the piping lines.

[0022] The single integrated valve provided by this invention can be directly connected to a dual-redundant piping system, while maintaining a compact structure and significantly reducing the overall size of the integrated valve. Through structural volume optimization and functional integration, this invention provides a novel multifunctional valve with a reasonable structure, reliable sealing, and integrated status monitoring and filtration functions. The valve provided by this invention features a compact structure, good sealing performance, and high functional integration, making it particularly suitable for flow management in "1+1" redundant dual-inlet flow systems.

[0023] The valve of this utility model brings the following beneficial effects:

[0024] (1) Functional integration: The check function of the dual inlet pipeline is integrated into a valve that supports dual inlets, and the valve disc of each inlet is decoupled.

[0025] (2) The structure is compact. The valve body adopts a square double inlet and integrated cavity design, which is reasonable and has low flow resistance.

[0026] (3) Good sealing performance: The independent valve disc design and built-in sealing ring groove ensure reliable sealing performance in both directions.

[0027] (4) By introducing a detection function interface, the valve and sensor installation interfaces are further integrated into one, realizing the collaborative work of fluid control and condition monitoring, simplifying the system structure and reducing installation and maintenance costs.

[0028] (5) Filtering impurities with low flow resistance: When a filter is further installed inside the outlet end of the valve, such as a cylindrical filter with the cylinder opening facing outward, the fluid must pass through the cylinder wall area of ​​the filter to flow out, thus achieving high-efficiency filtration in a limited space. After adding the filter, the integrated valve can not only effectively intercept impurities, but the cylindrical structure also has the advantages of large flow rate, low pressure drop, and robust and durable structure.

[0029] (6) It has wide applicability, especially suitable for complex working conditions in dual circulating water pump (generally with "1+1" redundant function) pipelines and where there are requirements for monitoring the system status, such as secondary side management of high-performance cooling capacity distribution unit (CDU), HVAC circulation system, industrial process circuit and fire protection network, etc. Attached Figure Description

[0047] The following will refer to the appendix Figure 1-8 The following describes and illustrates various exemplary embodiments of the present invention.

[0048] In dual-redundant piping systems, such as dual-circulating water pump systems, a 1+1 redundancy configuration is typically used. This means a primary and a backup piping system is configured, with a check valve installed in the outlet pipe of each pump. Only one piping system is operational at any given time, while the other serves as a standby or alternate operating system. Because dual-redundant piping systems require two check valves, this not only increases the overall piping volume but also raises the risk of leaks.

[0049] To address this, this invention provides an integrated valve that requires only one valve for two redundant pipelines, effectively reducing valve size and minimizing leakage risk. Through structural optimization, the integrated dual-inlet valve not only ensures decoupled operation of the two valve discs within the valve but also reduces the overall size of the integrated valve, while simultaneously increasing the ease of installation and installation.

[0050] The valve of this utility model has a wide range of applications, such as being particularly suitable for complex working conditions in dual circulating water pump (generally with "1+1" redundant function) pipelines where there are requirements for monitoring the system status, such as secondary side management of high-performance cooling capacity distribution units (CDU), HVAC circulation systems, industrial process circuits and fire protection pipe networks, etc.

[0051] See Figure 1-8 The valve component 100 includes a base 1 and a valve seat 2, with the base 1 and valve seat 2 fixedly connected. According to one example, the base 1 and valve seat 2 are fixedly connected by screws to form a complete valve body.

[0052] The valve 100 has two inlet ends and one outlet end, wherein the two inlet ends are arranged on one side of the valve seat 2 and the single outlet end is arranged on one side of the base 1.

[0053] Valve 100 can be connected to one of the pipelines in an external dual-redundant piping system via two inlet ends. A single outlet end can be connected to downstream components of both pipelines in the dual-redundant piping system, such as the outlet joints of the two pipelines. Therefore, the dual-redundant piping system requires only one valve 100, eliminating the need for a separate check valve for each pipeline. This significantly reduces the size of the check valves and piping, and lowers the risk of system leakage.

[0054] In some embodiments, the inlet end can be configured as an inlet pipe joint, for example, two inlet pipe joints 21 and 22 are fixedly connected to the valve seat 2, and an inlet passage for fluid is formed within each inlet pipe joint.

[0055] According to one example, the inlet pipe joint can be a pagoda-shaped straight pipe section, with valve seat 2 serving as the installation base. Two pagoda-shaped straight pipe sections are fixed on it by argon arc welding for connecting to the external inlet pipe.

[0056] The substrate 1 has two inlet channels arranged in a square shape and a cylindrical outlet channel to form an integral cavity 10.

[0057] The cavity 10 is U-shaped, with its two openings connected to an inlet channel of the valve seat 2, and its bottom connected to the outlet end of the valve. According to one example, each opening of the U-shaped cavity 10 is arranged in a square shape, and the bottom outlet end is configured as an outlet pipe connector, such as a cylindrical outlet pipe connector 11 extending outward from the base 1, which also forms a cylindrical outlet channel inside.

[0058] Two valve discs 23 and 24, each corresponding to an inlet end, are provided between the valve seat 2 and the cavity 10. Each valve disc is rotatably connected to the valve seat 2 to open or abut against the corresponding inlet channel, thereby opening or closing the corresponding inlet channel. When fluid flows in through an inlet end (such as inlet pipe joint 21), the valve disc 23 abutting against that inlet channel opens due to the fluid inflow. Subsequently, the fluid enters the cavity 10, and the fluid pressure inside the cavity 10 causes the other valve disc 24 to remain abutting against its corresponding inlet channel and remain in a closed state.

[0059] In some embodiments, two inlet pipe joints 21 and 22 are connected to external inlet pipes, and valve discs 23 and 24 abut against the inlet channels of inlet pipe joints 21 and 22, respectively. When fluid flows in from the external inlet pipe through inlet pipe joint 21, the valve disc 23 abutting against the inlet channel is opened by the fluid, and the fluid enters the U-shaped cavity 10, thereby applying pressure along the U-shaped channel to the valve disc 24 of the other inlet channel, causing the valve disc 24 to abut against its corresponding inlet channel and close that inlet channel.

[0060] According to one example, for instance, the inlet pipe connector 21 of valve 100 is connected to pipe I in a dual-circulation water pump pipeline, and the inlet pipe connector 22 is connected to pipe II in the dual-circulation water pump pipeline. When flow is flowing through pipe I, pipe II does not provide flow supply. When the water pump in pipe I is running, the inlet pressure on both sides of valve disc 23 in pipe I is greater than the outlet pressure, and valve disc 23 is pushed open by water (i.e., valve disc 23 is released from contact with the end of the inlet channel of pipe I), thus opening valve disc 23. At this time, the water pump in pipe II stops running, and the outlet pressure on both sides of valve disc 24 in pipe II is greater than the inlet pressure. Valve disc 24 is forcibly closed due to gravity and water pressure (i.e., valve disc 24 remains in contact with the end of the inlet channel of pipe II), closing valve disc 24, thereby preventing the fluid in the U-shaped cavity 10 from flowing back to the inlet of pipe II, and preventing backflow of water in pipe II.

[0061] The connection between the base 1 and the valve seat 2 is provided with two square communication ports. In one example, the base 1 has a first rectangular mounting structure 12, in which two first square communication ports 121 and 122 are arranged; the valve seat 2 has a second rectangular mounting structure 25 corresponding to the first rectangular mounting structure 12, in which two second square communication ports 251 and 252 are arranged, respectively corresponding to the first square communication ports 121 and 122.

[0062] The two first square connecting ports 121 and 122 of the base 1 are the inlets of the cavity 10, and the two second square connecting ports 251 and 252 of the valve seat 2 are respectively rotatably connected to a valve disc 23 and 24.

[0063] Valve discs 23 and 24 are thin, round, lightweight, and have low rotational resistance. Valve disc 23 has a mounting portion at its upper part, which is pivotally connected to valve seat 2 within the second square connection port 251 via a rotating shaft. Valve disc 24 has a mounting portion pivotally connected to valve seat 2 within the second square connection port 252 via a rotating shaft, thus forming two independent rotating pairs. This allows the two valve discs 23 and 24 to operate decoupled, opening and closing their respective inlet channels.

[0064] The rotating shaft pivotally connected to valve disc 23 and valve seat 2, and the rotating shaft pivotally connected to valve disc 24 and valve seat 2, can be the same rotating shaft or independent rotating shafts, both of which can achieve decoupled operation of valve discs 23 and 24.

[0065] According to one example, the upper outer side of the valve seat 2 has mounting holes 291 and 292 on both sides. The upper part of the second square connecting port 251 has a sleeve that mates with the upper mounting part of the valve disc 23. A rotating rod extends from the mounting hole 191 into the sleeve of the second square connecting port 251 and the valve disc 23, so that the second square connecting port 251 and the valve disc 23 are hinged, allowing the valve disc 23 to rotate around the rotating rod. The valve disc 24 is arranged in the same way, so that the second square connecting port 252 is hinged with the valve disc 24, allowing the valve disc 24 to rotate around the rotating rod. Thus, the valve seat 2 and the valve discs 23 and 24 cooperate to form two sealing rotating pairs, providing support and guidance for the valve discs 23 and 24, ensuring that the opening and closing actions of the valve discs 23 and 24 are precise and without jamming.

[0066] According to another example, the holes 291 and 292 on both sides of the upper part of the valve seat 2 are the two ends of a through hole. A rotating rod can be inserted into the through hole to make the valve discs 23 and 24 rotate around the rotating rod respectively, thereby realizing the decoupled operation of the valve discs 23 and 24.

[0067] The outer periphery of the two second square communication ports 251 and 252 of the valve seat 2 has grooves for placing a rubber ring, so as to form a sealing compression with the two first square communication ports 121 and 122 of the base 1. According to one example, the first rectangular mounting structure 12 and the second rectangular mounting structure 25 are both provided with multiple threaded holes, and the valve seat 2 is locked to the base 1 by screws, so that the rubber ring between the first rectangular mounting structure 12 and the second rectangular mounting structure 25 is compressed to form a seal.

[0068] The independent valve disc design and built-in sealing ring groove ensure 100% reliable bidirectional sealing performance of the valve.

[0069] In some embodiments, a filter 15 may also be arranged inside the outlet end of the valve body 100.

[0070] According to one example, the cylindrical outlet channel at the outlet end of the substrate 1 can house a porous cylindrical filter 15. The opening of the cylindrical filter 15 faces the outflow direction of the outlet channel, i.e., the outlet side of the outlet channel. The bottom and wall of the filter 15 can have different hole structures, for example, the bottom can be arranged with a circular hole structure and the wall with a square hole structure.

[0071] According to one example, the cylindrical outlet channel at the outlet end of the substrate 1 can house a double-layer cylindrical filter 15. The opening of the double-layer cylindrical filter 15 faces the outflow direction of the outlet channel, i.e., the outlet side of the outlet channel. The inner cylinder 151 can be a porous cylindrical structure, and the outer cylinder 152 can be a wire mesh structure. The bottom and wall of the inner cylinder can have different hole structures; for example, the bottom can be arranged with a circular hole structure, and the wall with a square hole structure.

[0072] The cylindrical filter 15 not only effectively intercepts impurities, but also has advantages such as large flow rate, low pressure drop, and robust and durable structure. Since the cylindrical opening of the filter 15 faces outward (outflow direction), the fluid in the cavity 10 must pass through the cylindrical wall area of ​​the filter 15 to flow out, thus achieving high-efficiency filtration within a limited space.

[0073] In some embodiments, a sensor mounting base is also arranged on the base 1, thereby enabling further integration of status detection functions, such as temperature sensors, pressure sensors, etc. In some embodiments, a pressure sensor mounting base 13 is arranged on the side (e.g., the right side) of the base 1 for mounting a pressure gauge to perform pressure measurement, and a temperature sensor mounting base 14 is arranged on the bottom side of the base 1 for mounting a thermometer to perform temperature measurement.

[0074] By introducing a detection function interface, such as integrating a dedicated sensor mounting interface on the base 1, the valve 100 is equipped with the ability to monitor fluid pressure and temperature in real time, realizing the coordinated operation of fluid control and condition monitoring, simplifying the system structure, and reducing installation and maintenance costs.

[0075] In one example, the base, valve seat, valve disc, sensor mount, and rotating shaft are all made of stainless steel. The sealing rubber ring is made of EPDM rubber. The screws are made of 10.9 grade galvanized carbon steel.

[0076] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
