Water conservancy project channel diversion control gate valve

Abstract

The invention discloses a diversion control gate valve for a water conservancy project channel, and belongs to the technical field of agricultural water-saving equipment. Comprising a flow dividing unit and a water saving unit, water flow discharged from the flow dividing unit enters the water saving unit through a pipeline and then is treated through a flow dividing device, and the water flow is subjected to multiple times of flow dividing and path adjustment in the flow dividing unit, so that the water flow becomes uniform and stable and is accurately controlled. The water flow is subjected to pressure regulation and flow speed control in a plurality of links in the process, so that the discharged water flow is ensured to have relatively high stability and controllability; the water flow discharged from the water-saving unit is generally in direct contact with a downstream system or a discharge port, and relatively speaking, the path of the water flow is more direct and simpler. In the process, the water flow is subjected to less shunting or pressure regulation, so that the discharged water flow has higher flow speed or larger pressure fluctuation; therefore, the device is suitable for water flow regulation and control under different conditions.

Description

Technical Field

[0001] The present invention relates to the technical field of agricultural water-saving equipment, and particularly relates to a diversion control gate valve for a water conservancy project channel. Background Art

[0002] In agricultural water-saving irrigation projects, channel diversion control is a key link to achieve efficient utilization and precise allocation of water resources. Traditional water flow distribution devices mostly adopt simple valves and diversion structures. However, in practical applications, these traditional devices have exposed many drawbacks, such as inaccurate water flow control, unstable diversion effect, and easy damage to equipment due to too fast flow velocity. Especially under some complex water flow conditions, traditional devices are difficult to meet the requirements of precise water flow control, stable diversion, and efficient discharge.

[0003] At present, with the continuous development of agricultural water-saving technologies, higher requirements are put forward for the diversion control system, including more efficient water flow regulation ability, more precise flow control, lower energy consumption, and longer service life. However, in the actual operation process of the existing water flow distribution devices, there are large energy losses and they are not applicable to water flow diversion in multiple states. Therefore, a diversion control gate valve for a water conservancy project channel is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and a diversion control gate valve for a water conservancy project channel is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A diversion control gate valve for a water conservancy project channel includes a diversion unit and a water-saving unit. The water-saving unit is vertically arranged on the side end face of the diversion unit. The diversion unit includes a bearing valve and a regulation mechanism that horizontally penetrates through the inner cavity of the bearing valve. A limiting mechanism is inserted into the inner cavity of the bearing valve, and the water-saving unit is inserted into the bottom of the bearing valve.

[0007] Preferably, the bearing valve includes a mounting plate and a bearing box installed at the middle position of the side end face of the mounting plate. A hollow cavity is opened in the inner cavity of the bearing box. A handle is installed on the outer end face of the bearing box, and a valve body is installed at the bottom of the mounting plate.

[0008] Preferably, the regulation mechanism includes an insertion frame and a guiding member horizontally inserted into the inner cavity of the insertion frame. Tensile members are arranged on the inner cavity wall of the insertion frame, and the tensile members clamp the outer end wall of the guiding member. Matching pipes are arranged at both ends of the insertion frame.

[0009] Preferably, the guiding member includes an elastic tube and an assembly frame installed between two groups of elastic tubes. Water flow grooves are arranged in a row on the side end face of the assembly frame. A communication cavity is formed in the inner cavity of the elastic tube. The inner cavity of the elastic tube communicates with the inner cavity of the water flow groove through the communication cavity. A flow splitting channel is transversely arranged in a row on the other side end face of the assembly frame. The water flow entering the inner cavity of the valve body will directly contact the bottom position of the guiding member. The water flow can penetrate through the inner cavity of the arranged flow splitting channels, and after the water flow is split, it enters the inner cavity of the water flow groove. The water flow can flow along a preset path, avoiding the formation of turbulent flow or eddy current, making the overall water flow direction more stable, improving the water conveyance efficiency. The water flow entering the inner cavity of the water flow groove can convey and split the water flow with the inner cavity wall of the communication cavity as the space.

[0010] Preferably, the stretching member includes a stretching block and built-in empty grooves formed on both sides at one end of the stretching block. Stretching bars are arranged in a row in the inner cavity of the built-in empty grooves. The other ends of the stretching bars are elastically connected to the side end face of the elastic tube, making the guiding member and the stretching member form an integral whole. Another flow splitting scheme is proposed. The matching tube is inserted into the water flow pipeline that needs to be split. The water flow penetrates through the inner cavities of the matching tube and the communication cavity and enters the water flow groove. Due to its fluidity, the water flow penetrates downward through the inner cavity of the flow splitting channel and then directly slides downward along the outer end wall of the guiding rods arranged in a circular array. When the water flow slides downward along the outer end wall of the guiding rods, due to the guiding effect of the wall surface design, the water flow movement is more stable, reducing the occurrence of turbulent flow and eddy current. The water flow drops and accumulates on the upper end face of the auxiliary baffle plate and is discharged through the through holes formed in the middle position, reducing the disturbance and energy loss of the water flow and improving the flow efficiency of the water flow. The water flow state discharged from the water saving unit is different from the water flow state discharged from the flow splitting unit.

[0011] Preferably, the limiting mechanism includes a valve stem and a handwheel installed at the top of the valve stem. A series connection member is arranged at the lower end face of the valve stem, and a blocking member is installed at the bottom position of the series connection member. The valve stem and the series connection member can rotate and adjust with the hollow cavity as the fulcrum.

[0012] The blocking member includes a plug tube and a communication frame installed between two groups of plug tubes. Buffer baffle plates are transversely arranged in a row in the inner cavity of the plug tube. The staff presses downward in the initial state of the handwheel, so that the bottom of the plug tube contacts the bottom position of the inner cavity wall of the water flow groove. Since the elastic tubes arranged on both sides are clamped by the arranged stretching members, at this time, the elastic tube will take its outer end point as the fulcrum and press downward and deform with the assembly frame as the midpoint, so that the water flow flowing into the device can only enter the inner cavity of the plug tube. The water flow is split again through the arranged buffer baffle plates, and the water flow volume entering the device in the pipeline can be accurately controlled, which helps to avoid excessive or insufficient flow passing through the device for splitting and ensure reasonable flow distribution in each part of the system.

[0013] Preferably, the plug tube is vertically inserted into the inner cavity of the water flow trough. The diameter of the outer end wall of the buffer baffle is the same as that of the inner cavity wall of the water flow trough. The staff holds the outer end of the handwheel and pulls the valve stem and the series connection member outwards, so that the bottom of the blocking member does not contact the inner cavity wall of the water flow trough. Rotate the handwheel by a certain degree. At this time, the bottoms of the two blocking members will directly contact the side end faces of the elastic tube and the assembly frame for positioning and support, improving the stability of the overall device during the flow splitting process;

[0014] When the inner cavity of the plug tube is full, the staff pulls the handwheel outwards, so that the water flow precisely controlled in the inner cavity of the plug tube is in the inner cavity of the water flow trough and penetrates into the inner cavity of the communication cavity for flow splitting treatment outside the device;

[0015] During the above flow splitting process, the path and flow direction of the water flow in the inner cavity wall of the elastic tube bent due to pressing are forced to change, and the water flow will decelerate. Because the water flow is affected by the bent wall surface, the local flow velocity decreases, so that the water flow state of the discharge device can be precisely controlled. The stable water flow helps to improve the operation efficiency of the entire hydraulic system, avoid the influence of water flow fluctuations on the downstream hydraulic performance. The decelerated water flow is more uniform and controllable, which helps to reduce energy loss, improve the hydraulic efficiency of the entire system, and ensure the efficient operation of the water conservancy project.

[0016] Preferably, the water-saving unit includes a positioning ring and guide rods annularly arrayed on the side end face of the positioning ring. The other end of the guide rod is attached to the auxiliary baffle. Four strengthening blocks are installed on the outer end wall of the auxiliary baffle. A through leakage hole is penetrated through the middle position at the bottom of the auxiliary baffle. The other end of the positioning ring is attached to the bottom end face of the valve body. When it is necessary to split the water flow in the farmland, the whole device is inserted into the inner cavity of the farmland pipeline with the water-saving unit as the insertion point. At this time, due to the positioning ring, guide rods and auxiliary baffle set as a support structure to support the inner cavity wall of the pipeline from the inside to the outside, and by setting strengthening blocks, a gap is formed between the auxiliary baffle and the inner cavity wall of the pipeline, so that the water flow in the farmland pipeline can flow along the arc of the outer end wall of the auxiliary baffle and flow out from the gap between the auxiliary baffle and the inner cavity wall of the pipeline. Due to the arc guidance, when the water flow accelerates, a Venturi effect will be formed, that is, the increase in flow velocity leads to a decrease in local pressure, which will further pull the surrounding water flow and accelerate the water flow through this area. Part of the water flow passes through the inner cavity of the through leakage hole and enters the inner cavity of the flow splitting unit synchronously with the water flow flowing along the edge for flow splitting treatment. The two water flows enter and mix synchronously, making the flow field more uniform, reducing local turbulence or eddy current, and improving the flow splitting effect. The two water flows interact in the inner cavity, which can reduce the impact of a single high-speed water flow on the pipeline or the gate valve, extend the service life of the equipment, and enable the whole device to form a positioning support with the pipeline during the flow splitting process and change the water flow state of the water flow about to enter the device.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When it is necessary to divert the water flow in the farmland, the whole device is inserted into the inner cavity of the farmland pipeline with the water-saving unit as the insertion point. At this time, due to the positioning ring, guide rod and auxiliary baffle plate set as the support structure, the inner cavity wall of the pipeline is supported from the inside out. And by setting the strengthening block, a gap is formed between the auxiliary baffle plate and the inner cavity wall of the pipeline, so that the water flow in the farmland pipeline can flow along the arc of the outer end wall of the auxiliary baffle plate and flow out from the gap between the auxiliary baffle plate and the inner cavity wall of the pipeline. Due to the arc guidance, the Venturi effect will be formed when the water flow accelerates, that is, the increase in flow velocity leads to a decrease in local pressure, which will further pull the surrounding water flow and accelerate the water flow through this area. Part of the water flow passes through the inner cavity of the permeable hole and enters the inner cavity of the diversion unit synchronously with the water flow flowing along the edge for diversion treatment. The two water flows enter and mix synchronously, making the flow field more uniform, reducing local turbulence or eddy current, improving the diversion effect. The two water flows interact in the inner cavity, which can reduce the impact of a single high-speed water flow on the pipeline or gate valve, extend the service life of the equipment, and enable the whole device to form a positioning support with the pipeline while changing the state of the water flow about to enter the device during the diversion process.

[0019] 2. The water flow entering the inner cavity of the valve body will directly contact the bottom position of the guide member. The water flow can pass through the inner cavities of the arranged diversion channels, and after the water flow is diverted, it enters the inner cavity of the water flow tank. The water flow can flow along the preset path, avoiding the formation of turbulence or eddy current, making the overall water flow direction more stable, and improving the water conveyance efficiency. The water flow entering the inner cavity of the water flow tank can convey and divert the water flow with the inner cavity wall of the communication cavity as the space.

[0020] 3. The staff presses down in the initial state of the handwheel, so that the bottom of the plug pipe contacts the bottom position of the inner cavity wall of the water flow tank. Because the elastic pipes arranged on both sides are clamped by the arranged tension members, at this time, the elastic pipes will take their outer end points as the fulcrum and press down and deform with the assembly frame as the midpoint, so that the water flow flowing into the device can only enter the inner cavity of the plug pipe. The water flow is diverted again through the opened buffer baffle, and the water volume entering the device from the pipeline can be accurately controlled, which helps to avoid excessive or insufficient flow passing through the device for diversion and ensure the reasonable flow distribution of each part in the system.

[0021] 4. Insert the mating pipe into the water flow pipeline that needs to be shunted. The water flow passes through the inner cavity of the mating pipe and the communication cavity and enters the water flow groove. After the water flow passes through the inner cavity of the shunt channel downward due to its fluidity, it directly slides downward along the outer end wall of the guiding rods arranged in an annular array. When the water flow slides downward along the outer end wall of the guiding rods, due to the guiding effect of the wall surface design, the water flow moves more smoothly, reducing the occurrence of turbulence and eddy current. The water flow drops and accumulates on the upper end surface of the auxiliary baffle plate and is discharged through the through holes opened in the middle position, reducing the disturbance and energy loss of the water flow and improving the flow efficiency of the water flow. The water flow state discharged from the water-saving unit is different from the water flow state discharged from the shunt unit. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Refer to Figures 1-9 , Embodiment 1, a diversion control gate valve for a water conservancy project channel, including a shunt unit 1 and a water-saving unit 2. The water-saving unit 2 is vertically arranged on the side end face of the shunt unit 1. The shunt unit 1 includes a bearing valve 11 and a regulation mechanism 12 that horizontally penetrates through the inner cavity of the bearing valve 11. The limiting mechanism 13 is interpenetrated in the inner cavity of the bearing valve 11. The water-saving unit 2 is penetrated at the bottom of the bearing valve 11.

[0034] The water-saving unit 2 includes a positioning ring 21 and guide rods 22 installed in an annular array on the side end face of the positioning ring 21. The other end of the guide rod 22 is in contact with the auxiliary retaining disc 23. Four groups of strengthening blocks 24 are installed on the outer end wall of the auxiliary retaining disc 23. A through leakage hole 25 is formed through the middle position at the bottom of the auxiliary retaining disc 23. The other end of the positioning ring 21 is in contact with the bottom end face of the valve body 115. When it is necessary to divert the water flow in the farmland, the whole device is inserted into the inner cavity of the farmland pipeline with the water-saving unit 2 as the insertion point. At this time, since the positioning ring 21, the guide rods 22 and the auxiliary retaining disc 23 are support structures that support the inner wall of the pipeline from the inside to the outside, and by setting the strengthening blocks 24, a gap is formed between the auxiliary retaining disc 23 and the inner wall of the pipeline, so that the water flow in the farmland pipeline can flow along the arc of the outer end wall of the auxiliary retaining disc 23 and flow out from the gap between the auxiliary retaining disc 23 and the inner wall of the pipeline. Due to the arc guidance, the Venturi effect will be formed when the water flow accelerates, that is, the increase in flow velocity leads to a decrease in local pressure, which will further pull the surrounding water flow and accelerate the water flow through this area. Part of the water flow passes through the inner cavity of the through leakage hole 25 and enters the inner cavity of the diversion unit 1 synchronously with the water flow flowing along the edge for diversion treatment. The two water flows enter and mix synchronously, making the flow field more uniform, reducing local turbulence or turbulent flow, and improving the diversion effect. The two water flows interact in the inner cavity, which can reduce the impact of a single high-speed water flow on the pipeline or the gate valve, extend the service life of the equipment, and enable the whole device to form a positioning support with the pipeline while changing the state of the water flow about to enter the device during the diversion process.

[0035] Embodiment 2, the bearing valve 11 includes a mounting disc 111 and a bearing box 112 installed at the middle position of the side end face of the mounting disc 111. A hollow cavity 113 is formed in the inner cavity of the bearing box 112. A handle 114 is installed on the outer end face of the bearing box 112. The valve body 115 is installed at the bottom of the mounting disc 111.

[0036] The regulation mechanism 12 includes an insertion frame 121 and a guide member 122 horizontally inserted in the inner cavity of the insertion frame 121. The inner cavity wall of the insertion frame 121 is arranged with tension members 123. The tension members 123 are clamped on the outer end wall of the guide member 122. The two ends of the insertion frame 121 are provided with mating pipes 124.

[0037] The guiding member 122 includes an elastic tube 1221 and an assembly frame 1222 installed between two groups of elastic tubes 1221. Water flow grooves 1223 are arranged on the side end face of the assembly frame 1222. A communication cavity 1224 is formed in the inner cavity of the elastic tube 1221. The inner cavities of the elastic tube 1221 and the water flow grooves 1223 are communicated through the communication cavity 1224. A diversion channel 1225 is transversely arranged on the other side end face of the assembly frame 1222. The water flow entering the inner cavity of the valve body 115 will directly contact the bottom position of the guiding member 122. The water flow can penetrate through the inner cavity of the arranged diversion channels 1225, and after the water flow is diverted, it enters the inner cavity of the water flow grooves 1223. The water flow can flow along a preset path, avoiding the formation of turbulent flow or eddy current, making the overall water flow direction more stable, improving the water conveyance efficiency. The water flow entering the inner cavity of the water flow grooves 1223 can convey and divert the water flow with the inner cavity wall of the communication cavity 1224 as the space.

[0038] Embodiment 3. The stretching member 123 includes a stretching block 1231 and built-in empty grooves 1232 formed on both sides of one end of the stretching block 1231. Stretching bars 1233 are arranged in the inner cavity of the built-in empty grooves 1232. The other ends of the stretching bars 1233 are elastically connected to the side end face of the elastic tube 1221, so that the guiding member 122 and the stretching member 123 are combined into a whole. Another diversion scheme is proposed. The fitting tube 124 is inserted into the water flow pipeline that needs to be diverted. The water flow penetrates through the inner cavities of the fitting tube 124 and the communication cavity 1224 and enters the water flow grooves 1223. Due to its fluidity, the water flow penetrates downward through the inner cavity of the diversion channels 1225 and then directly slides downward along the outer end wall of the guiding rods 22 arranged in a circular array. When the water flow slides downward along the outer end wall of the guiding rods 22, due to the guiding effect of the wall surface design, the water flow moves more smoothly, reducing the occurrence of turbulent flow and eddy current. The water flow drops and accumulates on the upper end face of the auxiliary baffle plate 23 and is discharged through the through holes 25 formed in the middle position thereof, reducing the disturbance and energy loss of the water flow and improving the flow efficiency of the water flow. The water flow state discharged from the water-saving unit 2 is different from the water flow state discharged from the diversion unit 1.

[0039] Embodiment 4. The limit mechanism 13 includes a valve stem 131 and a handwheel 132 installed at the top of the valve stem 131. A series connection member 133 is provided on the lower end surface of the valve stem 131, and a blocking member 134 is installed at the bottom position of the series connection member 133. The valve stem 131 and the series connection member 133 can be rotationally adjusted with the hollow cavity 113 as a fulcrum. The blocking member 134 includes a plug tube 1341 and a connecting frame 1342 installed between two groups of plug tubes 1341. Buffer baffles 1343 are arranged horizontally in the inner cavity of the plug tube 1341. When the staff presses down in the initial state of the handwheel 132, the bottom of the plug tube 1341 contacts the bottom position of the inner cavity wall of the water flow groove 1223. Since the elastic tubes 1221 arranged on both sides are clamped by the arranged tension members 123, at this time, the elastic tubes 1221 will take their outer endpoints as fulcrums and press downward and deform with the assembly frame 1222 as the midpoint, so that the water flowing into the device can only enter the inner cavity of the plug tube 1341. The water flow is further divided through the provided buffer baffles 1343, and the amount of water fluid entering the device in the pipeline can be accurately controlled, which helps to avoid excessive or insufficient flow through the device for diversion and ensure reasonable flow distribution in each part of the system.

[0040] Embodiment 5. The plug tube 1341 is vertically inserted into the inner cavity of the water flow groove 1223. The outer end wall diameter of the buffer baffle 1343 is the same as the inner cavity wall diameter of the water flow groove 1223. The staff holds the outer end of the handwheel 132 and stretches the valve stem 131 and the series connection member 133 outward, so that the bottom of the blocking member 134 does not contact the inner cavity wall of the water flow groove 1223. The handwheel 132 is rotated 90 degrees. At this time, the bottoms of the two groups of blocking members 134 will directly contact the side end faces of the elastic tube 1221 and the assembly frame 1222 for positioning and support, improving the stability of the overall device during the diversion process.

[0041] Embodiment 6. When the inner cavity of the plug tube 1341 is full, the staff pulls and draws the handwheel 132 outward, so that the water flow precisely controlled in the inner cavity of the plug tube 1341 is in the inner cavity of the water flow groove 1223 and penetrates into the inner cavity of the communication cavity 1224 for diversion treatment outside the device.

[0042] Embodiment 7. In the above embodiment, the path and flow direction of the water flow in the inner cavity wall of the elastic tube 1221 bent due to pressing are forced to change, and the water flow will decelerate. Because the water flow is affected by the bent wall surface, the local flow velocity decreases, so that the water flow state discharged from the device can be accurately controlled. The stable water flow helps to improve the operation efficiency of the entire hydraulic system, avoid the influence of water flow fluctuations on the downstream hydraulic performance. The decelerated water flow is more uniform and controllable, which helps to reduce energy loss, improve the hydraulic efficiency of the entire system, and ensure the efficient operation of the water conservancy project.

[0043] Working principle: When it is necessary to divert the water flow in the farmland, the whole device is inserted into the inner cavity of the farmland pipeline with the water-saving unit 2 as the insertion point. At this time, due to the positioning ring 21, the guide rod 22 and the auxiliary baffle 23 being a supporting structure to support the inner wall of the pipeline cavity from the inside out, and by setting the reinforcing block 24, a gap is formed between the auxiliary baffle 23 and the inner wall of the pipeline cavity, enabling the water flow in the farmland pipeline to flow along the arc of the outer end wall of the auxiliary baffle 23 and flow out from the gap between the auxiliary baffle 23 and the inner wall of the pipeline cavity. Due to the arc guidance, when the water flow accelerates, a Venturi effect will be formed, that is, the increase in flow velocity leads to a decrease in local pressure, which will further pull the surrounding water flow and accelerate the water flow through this area. Part of the water flow passes through the inner cavity of the permeable hole 25 and enters the inner cavity of the diversion unit 1 synchronously with the water flow flowing along the edge for diversion processing.

[0044] The water flow entering the inner cavity of the valve body 115 will directly contact the bottom position of the guide member 122. The water flow can pass through the inner cavities of the arranged diversion channels 1225, and after the water flow is diverted, it enters the inner cavity of the water flow groove 1223, and the water flow can flow along the preset path.

[0045] The staff holds the outer end of the handwheel 132 and pulls the valve rod 131 and the series connection member 133 outwards, so that the bottom of the blocking member 134 does not contact the inner wall of the water flow groove 1223. Rotate the handwheel 132 by 90 degrees. At this time, the bottoms of the two groups of blocking members 134 will directly contact the side end faces of the elastic tube 1221 and the assembly frame 1222 for positioning and support. The staff presses downwards in the initial state of the handwheel 132, so that the bottom of the plug tube 1341 contacts the bottom position of the inner wall of the water flow groove 1223. Because the elastic tubes 1221 arranged on both sides are clamped by the arranged stretching members 123, at this time, the elastic tube 1221 will take its outer end point as the fulcrum and press down and deform with the assembly frame 1222 as the midpoint, so that the water flow flowing into the device can only enter the inner cavity of the plug tube 1341, and the water flow is diverted again through the opened buffer baffle 1343.

[0046] When the inner cavity of the plug tube 1341 is full, the staff pulls the handwheel 132 outwards, so that the water flow precisely controlled in the inner cavity of the plug tube 1341 is in the inner cavity of the water flow groove 1223 and penetrates into the inner cavity of the communication cavity 1224 for diversion processing outside the device.

[0047] In the above embodiment, the path and flow direction of the water flow in the inner cavity wall of the elastic tube 1221 bent due to pressing are forced to change, and the water flow will decelerate because the water flow is affected by the bent wall surface, resulting in a local reduction in flow velocity. Thus, the water flow state of the discharge device can be accurately controlled. The stable water flow helps to improve the operating efficiency of the entire hydraulic system, avoid the influence of water flow fluctuations on the downstream hydraulic performance. The decelerated water flow is more uniform and controllable, which helps to reduce energy loss, improve the hydraulic efficiency of the entire system, and ensure the efficient operation of the water conservancy project.

[0048] Another shunt scheme is proposed. The fitting tube 124 is inserted into the water flow pipeline that needs to be shunted. The water flow passes through the inner cavity of the fitting tube 124 and the communication cavity 1224 and enters the water flow groove 1223. Due to its fluidity, the water flow passes through the inner cavity of the shunt channel 1225 vertically downward and then directly slides downward along the outer end wall of the guiding rod 22 arranged in an annular array. When the water flow slides downward along the outer end wall of the guiding rod 22, due to the guiding effect of the wall surface design, the water flow movement is more stable, reducing the occurrence of turbulence and eddy current. The water flow drops and accumulates on the upper end surface of the auxiliary baffle 23 and discharges the water flow through the through holes 25 opened in the middle position, reducing the disturbance and energy loss of the water flow, improving the flow efficiency of the water flow. The water flow state discharged from the water saving unit 2 is different from the water flow state discharged from the shunt unit 1.

[0049] In summary, a water conservancy project channel shunt control gate valve includes a shunt unit 1 and a water saving unit 2. The side end surface of the shunt unit 1 is vertically provided with the water saving unit 2. The shunt unit 1 includes a carrier valve 11 and a regulation mechanism 12 that horizontally penetrates through the inner cavity of the carrier valve 11. A limiting mechanism 13 is inserted into the inner cavity of the carrier valve 11. The water saving unit 2 is inserted through the bottom of the carrier valve 11. The water flow discharged from the shunt unit 1 enters the water saving unit 2 from the pipeline and then is processed by the shunt device. The water flow undergoes multiple shunts and path adjustments in the shunt unit 1, making the water flow uniform, stable, and precisely controlled. The water flow undergoes pressure regulation and flow velocity control in multiple links during this process to ensure that the discharged water flow has high stability and controllability.

[0050] The water flow discharged from the water saving unit 2 usually directly contacts the downstream system or the discharge port. Relatively speaking, the path of the water flow is more direct and simple. During this process, the water flow will undergo less shunt or pressure regulation, resulting in a higher flow velocity or larger pressure fluctuation of the discharged water flow; thus, it is applicable to water flow regulation in different situations.

[0051] The above is the entire working principle of the present invention.

[0052] In the present invention, the installation methods, connection methods or setting methods of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indexes of all their components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented, so no more details will be given.
