Description

Technical Field

[0001] The utility model relates to a water supply system, in particular to a pressurized and flow-increased water supply system for discontinuous water use. Background Art

[0002] There is a prior art water-driven water outlet pressurizing and flow-increasing system for a water purifier with a document number of CN207072860U, which includes a water-driven water outlet pressurizing and flow-increasing device, a multi-stage filtration system and a water pump. The water-driven water outlet pressurizing and flow-increasing device includes a sealed cylinder and an inner liner. The sealed cylinder is divided into a tap water storage chamber and a pure water storage chamber by the inner liner. The tap water storage chamber is connected to a tap water inlet through a connecting pipe, and the tap water storage chamber is connected to the water inlet end of the multi-stage filtration system through a connecting pipe. The water outlet end of the multi-stage filtration system is connected to the water inlet end of the water pump through a connecting pipe. The water outlet end of the water pump is connected to the pure water storage chamber through a connecting pipe. The pure water storage chamber is connected to a pure water outlet through a connecting pipe. An RO membrane is provided on the connecting pipe between the water pump and the pure water storage chamber. One end of a tee connecting pipe is connected to the pure water storage chamber through a connecting pipe, and the other two ends of the tee connecting pipe are respectively connected to the pure water outlet and the RO membrane water outlet through connecting pipes. A control valve is provided on the connecting pipe connected to the tap water inlet, and a control switch is provided on the connecting pipe connected to the pure water outlet. The inner liner is made of silica gel. However, it can only achieve pressurization and cannot increase the water source volume, thus unable to meet the need for increased water supply. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the above defects of the prior art and provide a pressurized and flow-increased water supply system for discontinuous water use.

[0004] To achieve the above object, the present utility model provides a pressurized and flow-increased water supply system for discontinuous water use. The special feature is that the water source pipeline supplies water to the auxiliary water tank through a bypass output pipe provided with a liquid level valve and a one-way valve or a control valve that automatically closes when the water level drops. The auxiliary water tank is connected to the water source pipeline provided with a booster pump on the downstream side through a bypass input pipe provided with a one-way valve. The downstream end of the water source pipeline is used to connect to discontinuous water use facilities. The booster pump can always be in the starting state during the use of discontinuous water use facilities; or the booster pump starts when pressurization is required and closes when pressurization is not required; it can also be that the booster pump starts when the discontinuous water use facility is operating and closes when it is not in the operating state. In this way, when water is used and the water supply is insufficient, supplementary water can be inhaled from the auxiliary water tank through the bypass input pipe, so as to meet the water volume requirement for water use; when water is not used, the water source pipeline can supply water to the auxiliary water tank through a bypass output pipe provided with a liquid level valve and a one-way valve or a control valve that automatically closes when the water level drops, so as to ensure that the auxiliary water tank can maintain the set water storage level. When water is used and the water supply pressure is insufficient, the water supply pressure can be increased by starting the booster pump, so as to meet the water pressure requirement for water use. In particular, since the supplementary water is instantaneously inhaled from the auxiliary water tank with pre-stored water, the normal water supply of the water source pipeline will not be affected during water replenishment; more particularly, when inhaling, the bypass output pipe prevents water injection into the auxiliary water tank through the liquid level valve and the one-way valve or the control valve that automatically closes when the water level drops, so as to avoid affecting the normal water supply efficiency of the water source pipeline. Since the water sucked more by the booster pump is replenished by the auxiliary water tank, it will not affect the water use of other users sharing the water source. It has the advantages of being able to increase pressure and flow rate without affecting the normal water supply capacity of the water source pipeline, meeting the water pressure and water volume requirements of discontinuous water use facilities, and not affecting the users sharing the water source, and solving the problem of insufficient water pressure and water volume in the water source pipeline.

[0005] As an optimization, a gas-water mixing device for sucking air into the pipeline is connected in series on the pipeline between the downstream end of the water source pipeline and the discontinuous water use facility, and the discontinuous water use facility is a flushing toilet. The introduction of the gas-water mixing device can improve the flushing and discharging efficiency of the toilet by adding air.

[0006] As an optimization, the gas-water mixing device is a gas-water mixing device including a self-priming device, a regulating valve and a gas storage tank arranged in a steam-water mixing tank. The arrangement in the steam-water mixing tank helps to reduce noise and is more conducive to avoiding condensation and dripping on the device body.

[0007] As an optimization, the regulating valve, the self-priming device and the gas storage tank are respectively arranged on two parallel branch pipes that are commonly connected to the upstream and downstream pipelines, which is more conducive to adjusting the working conditions of the gas-water mixing device. The gas-water mixing device is arranged lower than the water source pipeline, which is beneficial to ensuring the gas storage capacity under the condition of a low water pressure water source.

[0008] As an optimization, the liquid level valve is a float valve. It is easy to set up and maintain.

[0009] As an optimization, the discontinuous water-using facilities include flush toilets. Flush toilets are typical discontinuous water-using facilities, which are suitable for both pressure boosting and water-air mixing devices.

[0010] As an optimization, a pressure transmitter and a water flow sensor switch for electrically connecting and controlling the booster pump are arranged on the water source pipeline where the booster pump is set. The water pressure and water flow in the pipeline are sensed online to control the start and stop of the booster pump, which can ensure the water supply pressure and water volume for all water uses in the downstream pipeline; or a pressure transmitter for electrically connecting and controlling the booster pump is arranged on the water source pipeline where the booster pump is set, and the flush valve of the discontinuous water-using facility is linked to the start-stop switch for electrically connecting and controlling the booster pump, which is beneficial to avoid unnecessary start-up and is conducive to energy conservation.

[0011] As an optimization, the pressure transmitter and the water flow sensor switch or the pressure transmitter and the start-stop switch are electrically connected to control the booster pump through a controller. When the water flow sensor switch senses water flow or the start-stop switch is linked and the water pressure sensed by the pressure transmitter is less than the set value, the controller starts the booster pump, and in other cases, the booster pump is turned off.

[0012] As an optimization, the control valve that automatically closes when the water level drops is a normally open electric control valve arranged on the bypass output pipe, and a water flow switch for electrically connecting and controlling the normally open electric control valve is arranged on the bypass input pipe. In this way, it can be realized that when the auxiliary water tank outputs water, air is not input or the synchronous suction of air from the input pipe is avoided, resulting in the failure of water replenishment.

[0013] As an optimization, the auxiliary water tank is arranged lower than the water source pipeline. Even when the water pressure is very low, water injection can also be carried out through the gravity water flow.

[0014] In short, the system consists of four parts, namely an auxiliary water tank, a booster pump, a steam-water mixing tank, and discontinuous water-using facilities represented by water-using fixtures. The specific application process is as follows: The auxiliary water tank is replenished with water by the natural water pressure, and the water replenishment automatically stops when the tank is full. The booster pump is controlled to start by a pressure switch. When it starts, the water source pipeline and the auxiliary water tank replenish water together, and the replenishment ratio is water source pipeline 1: auxiliary water tank greater than 1 or X1, such as 1:9. The auxiliary water tank outputs water in inverse proportion to the water flow of the water source. The greater the water flow of the water source, the less the output water volume of the auxiliary water tank, and the smaller the water flow of the water source, the greater the output water volume of the auxiliary water tank. The pressurized water supply can go to the steam-water mixing tank, and after the steam-water mixing is completed in the tank, it leads to the flush valve or foot valve of the water-using fixture. At this time, the downstream system of the booster pump is in a high-pressure state. When people use it, they open the flush valve or step on the foot valve to complete the flushing. This system is reliable and stable, meets the usage requirements, has a low cost, is convenient for large-scale promotion, significantly improves the flushing effect, improves the cleanliness level of the public toilet environment, and reduces the cleaning burden.

[0015] After adopting the above technical solution, the pressure-boosting and flow-increasing water supply system for discontinuous water use of the present utility model has the advantages of being able to boost pressure and increase flow without affecting the normal water supply capacity of the water source pipeline, meeting the requirements of water pressure and water volume for discontinuous water use facilities, and not affecting the users of the shared water source, thus solving the problem of insufficient water pressure and water volume in the water source pipeline.

Figure 4 It is a schematic structural diagram of the fourth embodiment of the pressure-boosting and flow-increasing water supply system for discontinuous water use of the present utility model. Detailed Embodiment

[0017] Embodiment 1, as Figure 1As shown, the boosting and increasing flow rate water supply system for non-continuous water use of the utility model is that the water source pipeline 1 supplies water to the auxiliary water tank 4 through the bypass output pipe 11 provided with the liquid level valve 2 and the one-way valve 3, and the auxiliary water tank 4 is connected to the water source pipeline 1 with the boosting pump 5 on the downstream side through the bypass input pipe 12 provided with the one-way valve 3, and the downstream end of the water source pipeline 1 is used to connect the non-continuous water use facility 6. The boosting pump can be always in the starting state during the use of the non-continuous water use facility; or the boosting pump is started when the boosting is required and closed when the boosting is not required; it can also be that the non-continuous water use facility is started when the power is running and closed when it is not running. In this way, when water is used, if the water supply is insufficient, the supplementary water can be sucked from the auxiliary water tank through the bypass input pipe to meet the water demand for water use; when water is not needed, the water source pipeline can supply water to the auxiliary water tank through the bypass output pipe provided with the liquid level valve and the one-way valve or the liquid level valve and the control valve that automatically closes when the water level drops, thereby ensuring that the auxiliary water tank can maintain the set water storage level. When using water, if the water supply pressure is insufficient, the water supply pressure can be increased by turning on the booster pump to meet the water pressure requirements. In particular, since the water replenishment is immediately sucked from the auxiliary water tank that stores water in advance, the normal water supply of the water source pipeline will not be affected during water replenishment; more particularly, during suction, the bypass output pipe prevents water from being injected into the auxiliary water tank through its level valve and one-way valve or level valve and control valve that automatically closes when the water level drops, thereby avoiding affecting the normal water supply efficiency of the water source pipeline. Since the excess water sucked by the booster pump is replenished by the auxiliary water tank, it will not affect the water use of other users of the common water source. It has the advantages of being able to increase pressure and flow without affecting the normal water supply capacity of the water source pipeline, meeting the water pressure and water volume requirements of non-continuous water use facilities, and will not affect users of the shared water source, thus solving the problem of insufficient water pressure and water volume in the water source pipeline.

[0018] Specifically, the liquid level valve 2 is a float valve. The discontinuous water use facility 6 is a flushing squat toilet.

[0019] Specifically, a pressure transmitter and a water flow sensing switch electrically connected to control the booster pump 5 are arranged on the water source pipeline 1 where the booster pump 5 is arranged. The pressure transmitter and the water flow sensing switch are electrically connected to control the booster pump through a controller. When the water flow sensing switch senses the water flow or the start-stop switch is linked and the water pressure sensed by the pressure transmitter is less than the set value, the controller starts the booster pump, and shuts down the booster pump in other cases. The auxiliary water tank 4 is arranged lower than the water source pipeline 1. The auxiliary water tank 4 is arranged lower than the water source pipeline 1.

[0020] Embodiment 2, as Figure 2As shown in the figure, the difference between the pressure-increasing and flow-increasing water supply system for discontinuous water use of the present utility model and the first embodiment above is that: a gas-water mixing device for sucking air into the pipeline is connected in series on the pipeline between the downstream end of the water source pipeline 1 and the discontinuous water use facility 6. The gas-water mixing device is arranged below the water source pipeline 1. The gas-water mixing device is a gas-water mixing device including a self-priming device 71, a regulating valve 72 and a gas storage tank 70 arranged in a steam-water mixing tank 7. The regulating valve 72, the self-priming device 71 and the gas storage tank 70 are respectively arranged on two parallel branch pipes that jointly connect the upstream and downstream pipelines.

[0021] Embodiment 3, as Figure 3 As shown in the figure, the difference between the pressure-increasing and flow-increasing water supply system for discontinuous water use of the present utility model and the first embodiment above is that: the water source pipeline 1 supplies water to the auxiliary water tank 4 through a bypass output pipe 11 provided with a liquid level valve 2 and a control valve that automatically closes when the water level drops. The control valve that automatically closes when the water level drops is that a normally open electric control valve 8 is arranged on the bypass output pipe 11, and a water flow switch 81 for electrically connecting and controlling the normally open electric control valve 8 is arranged on the bypass input pipe 12.

[0022] Embodiment 4, as Figure 4 As shown in the figure, the difference between the pressure-increasing and flow-increasing water supply system for discontinuous water use of the present utility model and the first embodiment above is that: a pressure transmitter 51 for electrically connecting and controlling the booster pump 5 is arranged on the water source pipeline 1 where the booster pump 5 is arranged. The pressure transmitter 51 and the start-stop switch are electrically connected through a controller to control the booster pump 5. The flush valve 9 of the discontinuous water use facility is linked and electrically connected to the start-stop switch for controlling the booster pump 5. When the start-stop switch is linked and the water pressure sensed by the pressure transmitter 51 is less than the set value, the controller starts the booster pump 5.

[0023] In summary, the pressure-increasing and flow-increasing water supply system for discontinuous water use of the present utility model has the advantages of being able to increase pressure and flow under the premise of not affecting the normal water supply capacity of the water source pipeline, meeting the requirements of the discontinuous water use facility for the water supply pressure and quantity, not affecting the users of the common water source, and solving the problem of insufficient water pressure and quantity in the water source pipeline.
