Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipelines, in particular to a uniformly arranged water supply pipeline system. Background Art

[0002] Water supply pipelines can be used to transport and distribute water. During the construction process, multiple branches of water supply pipelines are generally connected to the main water supply pipeline. The water supply system can meet the needs of construction production water, construction machinery water, construction site water, domestic water and fire fighting water.

[0003] For example, the patent with the national authorized patent announcement number CN218031823U discloses a uniform layout system for water supply pipelines, which relates to the technical field of water supply pipelines to solve the problem of low efficiency in adjusting the distance between two groups of main water supply pipelines. It includes a bracket, an input pipeline and an output pipeline, both of which are arranged on the bracket, and the input pipeline and the output pipeline are located on the same axis, and also includes a connecting assembly, which includes two groups of mounting seats and a bellows arranged between the two groups of mounting seats, one group of mounting seats is detachably connected to the input pipeline, and the other group of mounting seats is detachably connected to the output pipeline, and a driving member for driving the two groups of mounting seats to move closer or farther along the axis direction of the input pipeline or the output pipeline is arranged on the bracket. This application has the effect of improving the adjustment efficiency of the distance between the input pipeline and the output pipeline, facilitating the uniform layout of the branch water supply pipeline, and improving the construction progress of the workers.

[0004] However, the above-mentioned uniform layout system of water supply pipelines does not have the function of allocating the water flow pressure (water flow rate) in each branch pipe. The lack of the ability to allocate water flow rate means that the water flow rates of different branch pipes may be different, which may result in higher water pressure in some areas and lower water pressure in other areas, making the water pressure of the water supply system unstable;

[0005] In some areas, if the water flows too fast, it will lead to waste of water resources. For example, in some places, if the water flows too fast and exceeds the actual needs, it will lead to excessive consumption and waste of water. Utility Model Content

[0006] The utility model aims to provide a uniformly arranged water supply pipe system to solve the problem in the above background technology that the system has no function of adjusting the water flow pressure (water flow rate) in each branch pipe.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A system for uniformly arranging water supply pipes comprises: a first valve, wherein the first valve can be connected to a main water supply pipe through a flange, the other end of the first valve is connected to a shunt pipe, a flow rate regulating mechanism is rotatably installed in the shunt pipe, the outer surface of the shunt pipe is connected to a water outlet pipe, the other end of the water outlet pipe is connected to a turbine flow sensor, the other end of the turbine flow sensor is connected to a shunt water pipe, and the other ends of multiple groups of shunt water pipes are all connected to a second valve.

[0009] Preferably, the signal transmitting end of the turbine flow sensor is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electrical control end of the flow rate control mechanism.

[0010] Preferably, a mounting tube is fixedly mounted on the upper end of the outer surface of the diverter tube, and the mounting tube sleeves the driving end of the flow rate regulating mechanism.

[0011] Preferably, the flow rate regulating mechanism comprises three groups of annular tubes, which are all rotatably installed in the diversion pipe, and the outer surface of the annular tube is provided with a docking port, which can be connected to the water outlet pipe to make them communicate.

[0012] Preferably, the annular tube can reduce the diameter of the water outlet pipe or cover and seal it by rotating.

[0013] Preferably, the three groups of ring tubes are connected in the shunt tube.

[0014] Preferably, a C-shaped ring is fixedly mounted on the outer surface of the annular tube, and the C-shaped ring is rotatably mounted in an annular groove, and the annular groove is provided on the inner wall surface of the shunt tube.

[0015] Preferably, the C-shaped ring passes through the connecting port into the installation tube, and the connecting port is opened on the outer surface of the shunt pipe.

[0016] Preferably, a gear ring is fixedly installed in the C-shaped ring, the gear ring is meshed with a gear, the gear is fixedly installed at one end of the output shaft of the motor, and the motor is fixedly installed in the installation cylinder.

[0017] Preferably, the electric control end of the motor is electrically connected to the output end of the controller.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. Through the design of the diversion pipe, water outlet, turbine flow sensor and flow rate control mechanism, when in use, the staff can connect the first valve to the main water supply pipe through the flange, and then supply water to the diversion pipe, and the diversion pipe can divide the water into three parts and supply it from the outlet pipe, and the water flowing out of the outlet pipe will enter the turbine flow sensor, and then flow out of the turbine flow sensor into the diversion water pipe, and multiple groups of diversion water pipes can be connected to multiple groups of branch water supply pipes, and the water demand of multiple places can be met through the main water supply pipe;

[0020] When water flows through the outlet pipe and enters the turbine flow sensor, the turbine flow sensor will detect the water flow pressure in the current outlet pipe. If the water flow pressure in the outlet pipe is lower than the set value, the turbine flow sensor will send a signal to the controller. The controller can control the flow rate control mechanism to reduce the pipe cross-sectional area of ​​the other two groups of outlet pipes. The water flow they can carry will decrease, so the total water flow in the system will also decrease, so that the flow rate of the water can be adjusted to reduce the speed of the water flowing through the outlet pipe, thereby reducing the water pressure in the pipe. The water flow rate of the outlet pipe whose pipe cross-sectional area is not currently regulated will increase, and then the water flow in the diversion pipe can be used to flow out from the outlet pipe with low water flow pressure at a greater pressure until the set value of the turbine flow sensor is reached. The flow rate control mechanism can be stopped, thereby achieving precise control of the water pressure, so that the water pressure at each branch in the pipeline system can be maintained within the required range, thereby ensuring the stability and reliability of the water supply system.

[0021] 2. Through the design of the motor, gear, annular tube, docking port, C-shaped ring and gear ring, if the water pressure in the outlet pipe is high, it will be detected by the turbine flow sensor, and the turbine flow sensor will send a signal to the controller, and the controller will control the motor in the current outlet pipe to drive the gear to mesh the transmission gear ring, and then drive the annular tube to rotate in the annular groove through the C-shaped ring, and as the annular tube rotates, the annular tube can drive the docking port to intersect with the outlet of the outlet pipe, and the annular tube will also block part of the outlet of the outlet pipe, thereby reducing the pipe cross-sectional area of ​​the outlet pipe, which can reduce the speed of the fluid passing through the outlet pipe, thereby reducing the water pressure in the outlet pipe, and the controller will stop driving the motor;

[0022] If the water pressure in the outlet pipe is low, the motor can be started to drive the connecting port of the ring pipe to be flush with the outlet pipe, thereby maximizing the increase in the pipe cross-sectional area of ​​the outlet pipe, increasing the speed of water flowing through the outlet pipe, and increasing the water pressure in the outlet pipe. If the pressure is still not enough, the other two groups of motors can be started to drive the connecting port of the ring pipe to intersect with the outlet pipe, thereby reducing the pipe cross-sectional area of ​​the other two groups, while the water pressure in the diversion pipe remains unchanged, so that the water flow can flow out of the outlet pipe whose pipe cross-sectional area has not been reduced at a higher water pressure. This is because when the pipe cross-section of the other two groups of outlet pipes is reduced, the water flow they can carry will decrease, so the total water flow in the system will also decrease, and the pipe cross-section of the current outlet pipe has not decreased, and thus the water flow has not changed, so its water flow rate or water pressure will increase accordingly.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-Figure 6 , this embodiment provides the following technical solutions:

[0032] like Figure 1-Figure 4 As shown, a system for uniformly arranging water supply pipes includes: a first valve 1, the first valve 1 can be connected to the main water supply pipe through a flange, the other end of the first valve 1 is connected to a shunt pipe 2, a flow rate regulating mechanism 6 is rotatably installed in the shunt pipe 2, the outer surface of the shunt pipe 2 is connected to a water outlet pipe 201, the other end of the water outlet pipe 201 is connected to a turbine flow sensor 3, the other end of the turbine flow sensor 3 is connected to a shunt water pipe 4, and the other ends of multiple groups of shunt water pipes 4 are all connected to a second valve 5.

[0033] The signal transmitting end of the turbine flow sensor 3 is connected to the signal receiving end of the controller, and the control output end of the controller is electrically connected to the electric control end of the flow rate control mechanism 6 .

[0034] A mounting cylinder 202 is fixedly mounted on the upper end of the outer surface of the shunt pipe 2 , and the mounting cylinder 202 sleeves the driving end of the flow rate regulating mechanism 6 therein.

[0035] Through the design of the shunt pipe 2, the water outlet 201, the turbine flow sensor 3 and the flow rate control mechanism 6, when in use, the staff can connect the first valve 1 to the main water supply pipe through the flange, and then supply water to the shunt pipe 2, and the shunt pipe 2 can divide the water into three parts and supply it from the water outlet pipe 201, and the water flowing out of the water outlet pipe 201 will enter the turbine flow sensor 3, and then flow out of the turbine flow sensor 3 into the shunt water pipe 4, and multiple groups of shunt water pipes 4 can be connected to multiple groups of branch water supply pipes, so that the water demand of multiple places can be met through the main water supply pipe;

[0036] When water flows through the outlet pipe 201 and enters the turbine flow sensor 3, the turbine flow sensor 3 will detect the water flow pressure in the current outlet pipe 201. If the water flow pressure in the outlet pipe 201 is lower than the set value, the turbine flow sensor 3 will send a signal to the controller, and the controller can control the flow rate control mechanism 6 to reduce the pipe cross-sectional area of ​​the other two groups of outlet pipes 201, so that the water flow they can carry will be reduced, and thus the total water flow in the system will also be reduced, thereby adjusting the flow rate of the water flow, so that the speed of the water flow through the outlet pipe 201 is reduced, thereby reducing the water pressure in the pipe, and the water flow speed of the outlet pipe 201 whose pipe cross-sectional area is not currently regulated will increase, and then the water flow in the diversion pipe 2 can be used to flow out of the outlet pipe 201 with a small water flow pressure at a greater pressure, until the set value of the turbine flow sensor 3 is reached, the flow rate control mechanism 6 can be stopped, thereby achieving precise control of the water pressure, so that the water pressure at each branch in the pipeline system can be maintained within the required range, thereby ensuring the stability and reliability of the water supply system.

[0037] It is worth noting that the turbine flow sensor 3 can be selected from the LWGY series: such as LWGY-10A, LWGY-150A0A3B0 / D, etc. These models are usually used to measure the flow of media such as water and liquids, and have the characteristics of high precision and high reliability.

[0038] The controller can be a DSP controller of TMS320F2812.

[0039] like Figure 5-Figure 6 As shown, the flow rate control mechanism 6 includes three groups of annular tubes 603, which are all rotatably installed in the diversion pipe 2. The outer surface of the annular tube 603 is provided with a docking port 604, which can be connected to the water outlet pipe 201 to make them communicate.

[0040] The ring pipe 603 can reduce the diameter of the water outlet pipe 201 or cover and seal it by rotating.

[0041] The three groups of ring tubes 603 are connected in the diverter tube 2 .

[0042] A C-shaped ring 605 is fixedly mounted on the outer surface of the annular tube 603 . The C-shaped ring 605 is rotatably mounted in the annular groove 203 . The annular groove 203 is formed on the inner wall surface of the diverter tube 2 .

[0043] The C-shaped ring 605 penetrates from the connection port 204 into the installation tube 202 . The connection port 204 is formed on the outer surface of the shunt pipe 2 .

[0044] A gear ring 606 is fixedly installed in the C-shaped ring 605 . The gear ring 606 meshes with the gear 602 . The gear 602 is fixedly installed at one end of the output shaft of the motor 601 . The motor 601 is fixedly installed in the installation tube 202 .

[0045] The electric control end of the motor 601 is electrically connected to the output end of the controller.

[0046] Through the design of the motor 601, the gear 602, the annular tube 603, the docking port 604, the C-shaped ring 605 and the gear ring 606, if the water pressure in the outlet pipe 201 is relatively high, it will be detected by the turbine flow sensor 3, and the turbine flow sensor 3 will send a signal to the controller, and the controller will control the motor 601 in the current outlet pipe 201 to drive the gear 602 to mesh with the transmission gear ring 606, and then drive the annular tube 603 to rotate in the annular groove 203 through the C-shaped ring 605, and as the annular tube 603 rotates, the annular tube 603 can drive the docking port 604 to intersect with the water outlet of the outlet pipe 201, and the annular tube 603 can also block part of the water outlet of the outlet pipe 201, thereby reducing the pipe cross-sectional area of ​​the outlet pipe 201, and can reduce the speed of the fluid passing through the outlet pipe 210, thereby reducing the water pressure in the outlet pipe 201, and the controller will stop driving the motor 601;

[0047] If the water pressure in the water outlet pipe 201 is low, the motor 601 can be started to drive the docking port 604 of the annular pipe 603 to be flush with the water outlet pipe 201, thereby maximizing the increase in the pipe cross-sectional area of ​​the water outlet pipe 201, thereby increasing the speed of water flowing through the water outlet pipe 201, and thereby increasing the water pressure in the water outlet pipe 201. If the pressure is still insufficient, the other two groups of motors 601 can be started to drive the docking port 604 of the annular pipe 603 to intersect with the water outlet pipe 201, thereby reducing the pipe cross-sectional areas of the other two groups, while the water pressure in the diversion pipe 2 remains unchanged, thereby allowing the water flow to flow out of the water outlet pipe 201 whose pipe cross-sectional area has not been reduced at a higher water pressure. This is because when the pipe cross-sections of the other two groups of water outlet pipes 201 are reduced, the water flow they can carry will decrease, so the total water flow in the system will also decrease, while the pipe cross-section of the current water outlet pipe 201 has not decreased, and thus the water flow has not changed, so its water flow speed or water pressure will increase accordingly.

[0048] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when in use, the staff can connect the first valve 1 to the main water supply pipe through the flange, and then supply water to the diversion pipe 2, and the diversion pipe 2 can divide the water into three parts and supply it from the outlet pipe 201, and the water flowing out of the outlet pipe 201 will enter the turbine flow sensor 3, and then flow out of the turbine flow sensor 3 into the diversion water pipe 4, and multiple groups of diversion water pipes 4 can be connected to multiple groups of branch water supply pipes, so as to meet the water demand of multiple places through the main water supply pipe;

[0049] When the water flows through the outlet pipe 201 and enters the turbine flow sensor 3, the turbine flow sensor 3 will detect the water flow pressure and water flow rate in the current outlet pipe 201. If the water flow pressure and water flow rate in the outlet pipe 201 are lower than the set value, the turbine flow sensor 3 will send a signal to the controller, and the controller can control the motor 601 in the current outlet pipe 201 to drive the gear 602 to mesh with the transmission gear ring 606, thereby driving the ring pipe 603 to rotate in the annular groove 203 through the C-shaped ring 605. As the ring pipe 603 rotates, the ring pipe 603 can drive the docking interface 604 to intersect with the water outlet of the outlet pipe 201, and the ring pipe 603 can also block part of the water outlet of the outlet pipe 201, thereby reducing the pipe cross-sectional area of ​​the outlet pipe 201, thereby reducing the speed of the fluid passing through the outlet pipe 210, thereby reducing the water pressure in the outlet pipe 201, and the controller will stop driving the motor 601.

[0050] If the water pressure in the water outlet pipe 201 is low, the motor 601 can be started to drive the docking port 604 of the annular pipe 603 to be flush with the water outlet pipe 201, thereby maximizing the increase in the pipe cross-sectional area of ​​the water outlet pipe 201, thereby increasing the speed of water flowing through the water outlet pipe 201, and thereby increasing the water pressure in the water outlet pipe 201. If the pressure is still insufficient, the other two groups of motors 601 can be started to drive the docking port 604 of the annular pipe 603 to intersect with the water outlet pipe 201, thereby reducing the pipe cross-sectional areas of the other two groups, while the water pressure in the diversion pipe 2 remains unchanged, thereby allowing the water flow to flow out of the water outlet pipe 201 whose pipe cross-sectional area has not been reduced at a higher water pressure. This is because when the pipe cross-sections of the other two groups of water outlet pipes 201 are reduced, the water flow they can carry will decrease, so the total water flow in the system will also decrease, while the pipe cross-section of the current water outlet pipe 201 has not decreased, and thus the water flow has not changed, so its water flow speed or water pressure will increase accordingly.

[0051] In summary: precise control of water pressure is achieved, so that the water pressure at each branch in the pipeline system can be maintained within the required range, thereby ensuring the stability and reliability of the water supply system.
