Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a flow regulating and water filling valve. Background Art

[0002] In the field of water conservancy engineering, the filling and drainage of pumped storage waterway systems is an indispensable operation in the construction management and operation and maintenance management of pumped storage power stations. For example, the initial filling and drainage test of the waterway system is a set of loading, unloading, inspection, observation, problem discovery and problem solving processes, which is the first test of the safe operation of the waterway system.

[0003] Since the filling head of the inlet / outlet gate filling valve of the pumped storage power station has a large amplitude, a large filling flow span, and must be able to be closed at any time to stop filling without water leakage, compared with the conventional power station gate, the inlet / outlet gate filling valve of the pumped storage power station must have better adaptability and adjustment capabilities. The type of filling valve is usually selected according to the water stop arrangement of the gate. For example, the rear water stop can generally be selected as a flat cover type or a plunger type, and the front water stop can be selected as a gate valve type.

[0004] However, in actual use, it was found that flat-cover or plunger-type filling valves are difficult to adapt to the flow control requirements during water filling, and thus cannot meet different water filling rate requirements. The gate valve type filling valve cannot meet the large flow requirements of later water filling, and cannot be partially opened to achieve flow regulation. Summary of the invention

[0005] In view of this, the present invention provides a flow regulating water filling valve to solve the problem that the existing water filling valve is difficult to meet the different water filling rate control requirements of various parts of the tunnel.

[0009] Beneficial effect: By providing a columnar connecting protrusion extending toward the first valve core on the second valve core, the columnar connecting protrusion serves as the main connection point and can withstand larger axial and radial forces. By providing an annular accommodating groove extending toward the first valve core on the second valve core, the first connecting hanger is allowed to move inside the annular accommodating groove after being sleeved on the outer side of the columnar connecting protrusion. The first connecting hanging shaft is used to limit the relative position between the first connecting hanger and the columnar connecting protrusion, which facilitates timely adjustment of the distance between the first valve core and the second valve core in the moving direction, thereby facilitating the two valve cores to achieve different opening adjustments, and further achieving precise control of the water filling flow.

[0017] Beneficial effects: By adding a first valve seat and installing the first valve seat at the end of the accommodating chamber away from the first transmission chamber, water leakage from the first valve seat is prevented, and the sealing inside the first valve housing is ensured. At the same time, the first valve seat serves as a supporting point for connecting the first valve housing with the outside world, achieving stable support, reducing the shaking amplitude and deviation degree of the first valve core during movement, ensuring that the first valve core moves accurately to the required position, thereby enhancing the stability of the overall structure of the flow regulating and water filling valve.

[0019] Beneficial effect: By adding a first water inlet pipe and a first water outlet pipe connected to the first transmission chamber, it is convenient to connect the flow regulating and filling valve to the water flow system, so that water flows into the first transmission chamber from the first water inlet pipe, passes through the throttling of the first valve core, and flows out from the first water outlet pipe, thereby effectively controlling the flow rate, pressure and direction of the water flow, so that the filling valve can be accurately adjusted according to actual needs, thereby meeting different water filling needs.

[0020] In an optional embodiment, the first water-filling structure further includes a first bushing, which is disposed at least on an inner wall of the first regulating chamber to provide guidance for movement of the first valve core.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Thus, a feature defined as "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] Combine the following Figures 1 to 9 , describing an embodiment of the present invention.

[0047] According to an embodiment of the present invention, a flow regulating water filling valve is provided, such as Figures 1 to 9 As shown, the flow regulating water filling valve includes a first water filling structure 1 and a second water filling structure 2.

[0048] Specifically, the first water-filling structure 1 at least includes a first valve housing 11 and a first valve core 12, the first valve core 12 is installed in the first valve housing 11, and the first valve core 12 moves in the first valve housing 11 under the action of external force, so as to adjust the throttling area of ​​the first valve core 12, thereby adjusting the opening degree of the first water-filling structure 1; the second water-filling structure 2 at least includes a second valve housing 21 and a second valve core 22, the second valve core 22 is installed in the second valve housing 21, and the second valve core 22 is connected to the first valve core 12 through a first connecting component 3, and the first connecting component 3 drives the second valve core 22 to move in the second valve housing 21 along the moving direction of the first valve core 12 under the action of the first valve core 12, so as to adjust the throttling area of ​​the second valve core 22, thereby adjusting the opening degree of the second water-filling structure 2, and the first connecting component 3 is also used to adjust the distance between the first valve core 12 and the second valve core 22 in the moving direction.

[0049] In this way, by setting up the linkage between the first water filling structure 1 and the second water filling structure 2, compared with the traditional single water filling valve, the flow regulating water filling valve of this structure can realize precise control of the water filling process, reduce energy waste, and meet the water filling rate requirements of different tunnel parts, thereby making the flow regulating water filling process more reliable.

[0050] Specifically, since the first valve core 12 and the second valve core 22 are respectively installed in their own independent valve housings and can be moved in the valve housings by external forces (such as water pressure, electric or hydraulic devices), their respective throttling areas can be flexibly adjusted, allowing operators to set and adjust the working states of the two valve cores according to the specific needs of different areas of the tunnel, to achieve partial opening, full closing or full opening, thereby achieving an ideal water filling rate.

[0051] At the same time, since there are two water filling structures, it can meet the large flow requirements of later water filling. When slow water filling is required to protect the stability of the structure, the opening of the corresponding valve core can be reduced to ensure that the flow regulating water filling valve can adapt to diverse needs.

[0052] In addition, through the setting of the first connecting component 3, the first valve core 12 and the second valve core 22 can achieve synchronous movement or asynchronous movement in the moving direction, which helps to reduce the problems of local scouring or pressure concentration caused by uneven water flow and improves the durability and safety of the follow-up structure.

[0053] Of course, compared with the traditional single water filling structure, the two water filling structures in the flow regulating water filling valve of this structure are relatively independent. When one of them fails, the other can continue to work, which is conducive to continuous water filling operations.

[0054] It can be explained that, in the present invention, the working stroke of the first valve core 12 and the process stroke of the second valve core 22 are not specifically limited and can be the same or different.

[0055] Preferably, in order to facilitate flexible adjustment, the working stroke of the first valve core 12 is greater than the working stroke of the second valve core 22 .

[0056] For example, the working stroke of the first valve core 12 is equal to the working stroke of the second valve core 22 and the size of the first transmission chamber 112 in the moving direction. At this time, the working stroke of the first valve core 12 is greater than the working stroke of the second valve core 22.

[0057] That is, as the first valve core 12 and the second valve core 22 reciprocate, the flow regulating water filling valve has: Figure 1 The first working state shown in FIG. 1 is that the first valve core 12 is fully opened and the second valve core 22 is fully opened. Figure 7 The first valve core 12 is fully opened and the second valve core 22 is fully closed in the second working state, as shown in FIG. Figure 8 The third working state in which the first valve core 12 is partially opened and the second valve core 22 is completely closed is shown, and Fig. 9 The fourth working state shown is that the first valve core 12 is completely closed and the second valve core 22 is completely closed.

[0058] That is, the flow regulating water filling valve has a large head variation. When the water head is high, the first water filling structure 1 and the second water filling structure 2 can be controlled separately to control the water inlet flow of each water filling structure. When the water head is low, the first valve core 12 can be partially opened and the second valve core 22 can be completely closed for regulation.

[0059] In this configuration, when the first valve core 12 is in a fully open state, the second valve core 22 is in a fully closed state.

[0060] Of course, in other optional embodiments, for example, when the working stroke of the first valve core 12 is equal to the working stroke of the second valve core 22, the flow regulating and water filling valve has: a working state in which the first valve core 12 is fully open and the second valve core 22 is fully open; a working state in which the first valve core 12 is partially open and the second valve core 22 is partially open; and a working state in which the first valve core 12 is fully closed and the second valve core 22 is fully closed, which will not be repeated here.

[0061] In one embodiment, Figures 1 to 9 As shown, the second valve core 22 is provided with a columnar connecting protrusion 221 and an annular accommodating groove 222 extending toward the first valve core 12, the annular accommodating groove 222 is arranged around the columnar connecting protrusion 221, and the side of the annular accommodating groove 222 close to the first valve core 12 is open; the first connecting component 3 includes at least a first connecting hanging plate 31 and a first connecting hanging shaft 32, the end of the first connecting hanging plate 31 away from the second valve core 22 is used to connect with the first valve core 12, the end of the first connecting hanging plate 31 close to the second valve core 22 is used to be sleeved on the outside of the columnar connecting protrusion 221, and the end of the first connecting hanging plate 31 close to the second valve core 22 moves in the annular accommodating groove 222; the first connecting hanging shaft 32 is used to limit the relative position between the end of the first connecting hanging plate 31 close to the second valve core 22 and the columnar connecting protrusion 221.

[0062] In this way, by providing a columnar connecting protrusion 221 extending toward the first valve core 12 on the second valve core 22, the columnar connecting protrusion 221 serves as the main connecting point and can withstand larger axial and radial forces. By providing an annular accommodating groove 222 extending toward the first valve core 12 on the second valve core 22, the first connecting hanger plate 31 is allowed to move inside the annular accommodating groove 222 after being sleeved on the outer side of the columnar connecting protrusion 221. The first connecting hanging shaft 32 is used to limit the relative position between the first connecting hanger plate 31 and the columnar connecting protrusion 221, so as to facilitate timely adjustment of the distance between the first valve core 12 and the second valve core 22 in the moving direction, thereby facilitating the two valve cores to achieve different opening adjustments, and further achieving precise control of the water filling flow.

[0063] At the same time, after installation, the second valve core 22, the first connecting hanger plate 31, the first connecting hanger shaft 32 and the first valve core 12 present a more reliable and stable disassembly connection method. When maintenance and replacement of corresponding parts are required, it is easy to disassemble and reassemble, reducing downtime and maintenance costs.

[0064] In addition, since the distance between the first valve core 12 and the second valve core 22 in the moving direction can be adjusted, when the second valve core 22 is fully closed and the first valve core 12 is not fully closed, the annular accommodating groove 222 can be set to provide a moving basis for the first connecting hanger plate 31 to continue to move, thereby facilitating the full closure of both valve cores.

[0065] It can be explained that, in the moving direction, the depth of the annular accommodating groove 222 is equal to the length of the first waist-shaped hole 311 , so that when the first valve core 12 is fully closed, the first connecting hanging plate 31 is placed in the annular accommodating groove 222 .

[0066] It can be explained that the specific location of the columnar connection protrusion 221 is not specifically limited.

[0067] Preferably, in order to reduce the shaking degree of the first valve core 12 and the second valve core 22 during the movement, the columnar connecting protrusion 221 is centrally arranged at the end of the second valve core 22 close to the first valve core 12 .

[0068] In one embodiment, Figures 1 to 9 As shown, the first connecting hanging plate 31 is arranged between the first valve core 12 and the second valve core 22 along the moving direction of the first valve core 12, and a limiting hole is opened on the side wall of one of the end of the first connecting hanging plate 31 close to the second valve core 22 and the columnar connecting protrusion 221, and a first waist-shaped hole 311 is opened on the side wall of the other of the two; the first connecting hanging shaft 32 is passed through the first waist-shaped hole 311 and the limiting hole.

[0069] In this way, by opening a limiting hole in one of the first connecting hanger plate 31 and the columnar connecting protrusion 221, opening a first waist-shaped hole 311 in the other, and using the first connecting hanger shaft 32 for penetration connection, it is ensured that the relative position between the connecting parts will not be easily changed due to external factors such as vibration and temperature changes, making the connection relationship more stable and improving the reliability of the flow regulating and water filling valve during operation.

[0070] At the same time, the flow regulating and water filling valve can also fine-tune the relative position between the first connecting hanging plate 31 and the columnar connecting protrusion 221 during use, providing convenience for adjusting the relative spacing between the two valve cores in the moving direction, avoiding the movement interference that occurs when the hanging shaft is passed through the two limit holes, and making the process of adjusting the relative spacing between the two valve cores in the moving direction more reliable.

[0071] It can be explained that in the present invention, the shape of the limiting hole is not specifically limited. It can be the same as the first waist-shaped hole 311, that is, a long strip-shaped hole, or it can be different from the first waist-shaped hole 311, such as a round hole, a square hole, etc., and it is sufficient to make the inner wall of the limiting hole conform to the outer wall of the first connecting suspension shaft 32.

[0072] It can be explained that the first connecting assembly 3 further includes a suspension rod 33 , and at this time, two ends of the suspension rod 33 arranged along the moving direction of the valve core are respectively connected to the first valve core 12 and the first connecting suspension plate 31 .

[0073] Furthermore, a connecting piece is added at the connection between the suspension rod 33 and the first connecting suspension plate 31 , and the connecting piece is used to connect the suspension rod 33 and the first connecting suspension plate 31 , and is connected in a manner of being welded to the first connecting suspension plate 31 and detachably connected to the connecting suspension rod 33 .

[0074] In one embodiment, Figures 1 to 9 As shown, the first valve housing 11 is provided with a first regulating chamber 111 and a first transmission chamber 112. The first transmission chamber 112 is spaced apart from and connected to the first regulating chamber 111 in the moving direction. The first valve core 12 moves between the first regulating chamber 111 and the first transmission chamber 112.

[0075] In this way, by arranging the first transmission chamber 112 and the first regulating chamber 111 to be spaced apart and connected in the moving direction, the first valve core 12 is allowed to move between the first regulating chamber 111 and the first transmission chamber 112, providing a sufficient moving area, so that the first valve core 12 can effectively regulate the water flow in the transmission chamber, and the flow rate and pressure of the water flow in the first transmission chamber 112 can be controlled by changing the position of the first valve core 12, thereby meeting different water filling requirements.

[0076] At the same time, since the first valve core 12 moves between the first regulating chamber 111 and the first transmission chamber 112, its moving path is a continuous linear type, which can reduce the wear of the valve core during movement, help reduce the pauses that occur during the movement of the valve core, and thereby reduce the vibration and noise generated.

[0077] In addition, such a setting helps to achieve precise adjustment of the opening degree of the valve core, thereby accurately controlling the water flow.

[0078] It can be explained that, in the present invention, in the moving direction of the first valve core 12, the size of the first regulating chamber 111 should ensure that when the first valve core 12 is fully opened, 2 / 3 of the length of the first valve core 12 is still located in the first regulating chamber 111 to facilitate the first valve core 12 to be stuck during movement.

[0079] In one embodiment, Figures 1 to 9 As shown, the first valve housing 11 is also provided with a accommodating chamber 113. In the moving direction of the first valve core 12, the accommodating chamber 113 is located on the side of the first transmission chamber 112 away from the first regulating chamber 111, and the accommodating chamber 113 is arranged at the same time as the first transmission chamber 112 and the first regulating chamber 111.

[0080] In this configuration, by adding the accommodating chamber 113 and coaxially arranging the accommodating chamber 113 , the first transmission chamber 112 and the first regulating chamber 111 , a temporary storage space is provided for the first valve core 12 when it moves.

[0081] In one embodiment, Figures 1 to 9 As shown, the first water-filling structure 1 further includes a first valve seat 13 . In the moving direction of the first valve core 12 , the first valve seat 13 is installed at the end of the accommodating chamber 113 away from the first transmission chamber 112 .

[0082] In this configuration, by adding the first valve seat 13 and installing the first valve seat 13 at the end of the accommodating chamber 113 away from the first transmission chamber 112 , water leakage from the first valve seat 13 is prevented, thereby ensuring the sealing inside the first valve housing 11 .

[0083] At the same time, the first valve seat 13 serves as a supporting point for connecting the first valve housing 11 with the outside world, thereby achieving stable support, reducing the shaking amplitude and deviation degree of the first valve core 12 during movement, and ensuring that the first valve core 12 accurately moves to the required position, thereby enhancing the stability of the overall structure of the flow regulating and water filling valve.

[0084] It can be explained that, since the suspension rod 33 needs to connect the first valve core 12 and the first connecting suspension plate 31 when being installed, the first valve seat 13 is provided with a through hole for the suspension rod 33 to pass through.

[0085] Furthermore, a sealing member 34 is provided at the through hole to ensure the sealing between the first valve seat 13 and the suspension rod 33 .

[0086] In one embodiment, Figures 1 to 9 As shown, the first water-filling structure 1 also includes a first water inlet pipe 14 and a first water outlet pipe 15, which are respectively arranged on the water inlet side and the water outlet side of the first transmission chamber 112, and the first water inlet pipe 14 and the first water outlet pipe 15 are both connected to the first transmission chamber 112.

[0087] With such a configuration, by adding a first water inlet pipe 14 and a first water outlet pipe 15 connected to the first transmission chamber 112, it is convenient to connect the flow regulating and filling valve to the water flow system, so that water flows into the first transmission chamber 112 from the first water inlet pipe 14, passes through the throttling of the first valve core 12, and flows out from the first water outlet pipe 15, thereby effectively controlling the flow rate, pressure and direction of the water flow, so that the filling valve can be accurately adjusted according to actual needs, thereby meeting different water filling needs.

[0088] In one embodiment, Figures 1 to 9 As shown, the first water-filled structure 1 further includes a first bushing 16 , which is at least disposed on the inner wall of the first regulating chamber 111 to provide guidance for the movement of the first valve core 12 .

[0089] In this way, by providing a first bushing 16 on the inner wall of the first regulating chamber 111, the friction and resistance of the first valve core 12 during movement can be reduced, ensuring that the first valve core 12 can move smoothly and stably, helping to prevent the first valve core 12 from shaking or shifting during movement, ensuring that the valve core stably moves to the required position, and extending the service life of the first valve core 12 and the first valve housing 11, reducing maintenance and reducing the frequency of replacement.

[0090] At the same time, the first bushing 16 can also provide guidance for the movement of the first valve core 12, ensuring that the valve core moves accurately to the desired position, thereby ensuring accurate control of the water flow.

[0091] It can be explained that, in the present invention, the first bushing 16 is also arranged on the inner wall of the first transmission chamber 112 and the inner wall of the accommodating chamber 113 .

[0092] It can be explained that in the present invention, the second valve housing 21 in the second water-filling structure 2 is similar to the first valve housing 11 in the first water-filling structure 1. At this time, the second valve housing 21 is provided with a second regulating chamber 211 and a second transmission chamber 212 spaced apart in the moving direction of the second valve core 22.

[0093] Furthermore, a limit chamber 213 is provided inside the second valve housing 21 and is arranged in the moving direction of the second valve core 22. At this time, the limit chamber 213 is arranged on the side of the second transmission chamber 212 away from the second regulating chamber 211, and at least one limit member 27 extending toward the second transmission chamber 212 is provided in the limit chamber 213.

[0094] Furthermore, in the moving direction, a second valve seat 23 is installed at the end of the limiting chamber 213 away from the second transmission chamber 212 .

[0095] In one embodiment, Figures 1 to 9 As shown, in the moving direction of the second valve core 22 , the size of the second transmission chamber 212 should be smaller than or equal to the size of the second valve core 22 .

[0096] In one embodiment, Figures 1 to 9 As shown, the end of the limit member 27 close to the second transmission chamber 212 can be flush with the bottom end surface of the second transmission chamber 212, or the end of the limit member 27 close to the second transmission chamber 212 is lower than the bottom end surface of the second transmission chamber 212. At this time, the size of the second valve core 22 should meet the following requirements: after the second valve core 22 is in place, that is, after the second valve core 22 contacts the limit member 27, the second valve core 22 can also completely block the water flow in the second transmission chamber 212.

[0097] In one embodiment, Figures 1 to 9 As shown, the second water-filled structure 2 further includes a second bushing 26 . In this case, the second bushing 26 is at least disposed on the inner wall of the second regulating chamber 211 .

[0098] In one embodiment, Figures 1 to 9 As shown, the second water-filling structure 2 also includes a second water inlet pipe 24 and a second water outlet pipe 25, which are respectively arranged on the water inlet side and the water outlet side of the second transmission chamber 212, and the second water inlet pipe 24 and the second water outlet pipe 25 are both connected to the second transmission chamber 212.

[0099] Preferably, the second bushing 26 is also disposed on the inner wall of the second transmission chamber 212 and the inner wall of the limiting chamber 213 .

[0100] It can be explained that the diameters of the first water inlet pipe 14, the first water outlet pipe 15, the second water inlet pipe 24 and the second water outlet pipe 25 are determined according to the water flow velocity and the capacity of the flow regulating and filling valve.

[0101] Furthermore, in the moving direction of the first valve core 12 or the second valve core 22 , the radial dimension of the inner wall of the first water inlet pipe 14 is the same as the length of the first transmission chamber 112 , and the radial dimension of the inner wall of the second water inlet pipe 24 is the same as the length of the second transmission chamber 212 .

[0102] In one embodiment, Figures 1 to 9 As shown, the flow regulating and water filling valve also includes a second connecting component 4, and the second connecting component 4 includes an opening and closing hanging plate 41. In the moving direction of any valve core, the end of the opening and closing hanging plate 41 close to the first valve core 12 is detachably connected to the first valve core 12, and the end of the opening and closing hanging plate 41 away from the first valve core 12 is connected to the opening and closing machine through a hanger.

[0103] In this configuration, by adding the opening and closing hanging plate 41, the first valve core 12 can be connected to the opening and closing machine through the hanging device, so that the opening and closing hanging plate bears the weight of the entire gate, and the hanging device only bears the weight of the valve core.

[0104] At the same time, since the opening and closing hanging plate 41 and the first valve core 12 are connected in a disassembly manner, when the valve core needs to be repaired or replaced, the connecting hanging plate can be disassembled more quickly and easily, and then the first valve core 12 can be taken out for inspection or replacement, thereby improving the flexibility of repair and replacement, eliminating the need for complete disassembly, and reducing maintenance costs.

[0105] It can be explained that the opening and closing hanging plate 41 is detachably connected to the first valve core 12 through the second connecting hanging plate 42 and the third connecting hanging shaft 43.

[0106] Specifically, in the moving direction of the first valve core 12, another columnar connecting protrusion 221 is provided at the end of the first valve core 12 close to the opening and closing hanger plate 41. At this time, the columnar connecting protrusion 221 extends toward the opening and closing hanger plate 41, and a second connecting hanger plate 42 is provided at the end of the opening and closing hanger plate 41 close to the first valve core 12. The second connecting hanger plate 42 and the columnar connecting protrusion 221 are both provided with limiting holes, and the two limiting holes are coaxial, which helps to fix the second connecting hanger plate 42 and the columnar connecting protrusion 221 of the first valve core 12 after the third connecting hanging shaft 43 is penetrated.

[0107] In one embodiment, Figures 1 to 9 As shown, the opening and closing hanging plate 41 is provided with a second waist-shaped hole 411 and a third waist-shaped hole 412. In the moving direction of the first valve core 12, the second waist-shaped hole 411 is located on the side of the first valve core 12 away from the second valve core 22. The third waist-shaped hole 412 and the second waist-shaped hole 411 are arranged at intervals, and the third waist-shaped hole 412 is located on the side of the second waist-shaped hole 411 away from the first valve core 12; the flow regulating and water filling valve also includes a main shell 51, a second connecting hanging shaft 52 and a guide shaft 53, and the interior of the main shell 51 is used to install the first water filling structure 1 and the second water filling structure 2; the second connecting hanging shaft 52 is fixed to the main shell 51 at one end along its axis, and the second connecting hanging shaft 52 extends into the second waist-shaped hole 411 along the other end of its axis and is slidably connected to the second waist-shaped hole 411; the guide shaft 53 is fixed to the main shell 51 at one end along its axis, and the guide shaft 53 extends into the third waist-shaped hole 412 along the other end of its axis and is slidably connected to the third waist-shaped hole 412.

[0108] With such an arrangement, through the arrangement of the hanging shaft and the second waist-shaped hole 411, the opening and closing machine can quickly respond to operating instructions, drive the opening and closing hanging plate 41 to move, and then drive the first valve core 12 to move. Through the arrangement of the guide shaft 53 and the third waist-shaped hole 412, the opening and closing hanging plate 41 is provided with guidance during the movement process, so that it moves along a predetermined trajectory, which helps to reduce the shaking and deviation of the opening and closing hanging plate 41 during the movement process, thereby ensuring that the first valve core 12 and the second valve core 22 will not shake or deflect during the movement process, thereby making the opening and closing process of the flow regulating and water filling valve more stable.

[0109] In one embodiment, Figures 1 to 9 As shown, the opening and closing hanging plate 41 is also provided with a mounting hole 413, and the mounting hole 413 is used to install the hanging wheel.

[0110] It should be noted that in the above embodiment, there is no specific limitation on the hanging device, and it is only required to be able to hang the opening and closing hanging plate 41.

[0111] Preferably, the hoist is a steel wire rope of the gate hoist, in which case one end of the steel wire rope is connected to the reel of the gate hoist, and the other end of the steel wire rope is connected to the hanging wheel.

[0112] It can be explained that, in the present application, a gate hoist and a hoist are also used to lift the main shell 51, so that the main shell 51 and the gate hoist plate 41 can move relatively.

[0113] Specifically, in actual use, after the gate hoist lifts the main shell 51 and places it in the tunnel, the gate hoist can lift the gate hoist plate 41 alone, and then control the lifting and lowering of the first valve core 12 and the second valve core 22, thereby controlling the opening of the first water-filling structure 1 and the second water-filling structure 2.

[0114] It can be explained that the moving direction mentioned in the above embodiment is the height direction, that is, Figures 1 to 9 Therefore, the first water-filled structure 1 and the second water-filled structure 2 can realize the linkage movement in the vertical direction.

[0115] When the flow regulating and water filling valve provided in this embodiment is in use, the opening and closing machine is started to complete the landing of the main shell 51 first, and then the opening and closing machine lifts the opening and closing hanging plate 41, and the first valve core 12 and the second valve core 22 gradually fall into place. Since the working stroke of the first valve core 12 is equal to the working stroke of the second valve core 22 and the size of the first transmission chamber 112 in the moving direction, the first valve core 12 is in a fully open state and the second valve core 22 is completely closed. At this time, the opening and closing hanging plate 41 continues to descend until the first valve core 12 is completely closed.

[0116] By connecting two-stage water filling structures in series vertically, flow adjustment can be achieved according to different needs. Specifically, when high head is required, any one of the water filling structures can be opened, or both water filling structures can be opened at the same time to control the water volume and avoid vibration. At the same time, compared with the traditional plunger-type water filling valve, the flow adjustment water filling valve of this structure will not cause the valve core to be blocked by debris on the top of the door, which will cause the valve core to be unable to close, thereby solving the problem of valve core blockage.

[0117] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
