Description

Technical Field

[0001] This application relates to the field of pipeline internal cleaning equipment, and more specifically, to a pipeline flushing device. Background Art

[0002] In various industrial and civil facilities, the pipeline system, as a key part of fluid transmission, its cleanliness and operating efficiency directly affect the performance and lifespan of the overall system. Especially in fields such as metallurgical factories, chemical enterprises, and urban water supply and drainage systems, various impurities, sediments, and even corrosive substances often accumulate inside the pipelines due to long-term use. These pollutants not only reduce the flow capacity of the pipelines but may also damage the pipeline materials, leading to serious problems such as leaks and blockages. Therefore, how to effectively flush and clean the pipelines has become a technical problem that urgently needs to be solved.

[0003] Currently, the pulse pipeline cleaning machines on the market have relatively single functions. Many of them only have one check valve, and the installed water pumps are used separately. Existing pulse cleaning machines are all composed of a separate water pump suction port, a water pump discharge port, a pulse outlet, and a tap water inlet, a total of 4 ports. If the water pump is to be used, the pipes need to be reconnected. The water pump needs to be connected in series to the tap water inlet of the pulse cleaning machine for use. Moreover, the water pumps basically do not have a pressure regulating system. Some also directly reduce the voltage of the water pump through the circuit board. In this case, if the pressure is applied or blocked, the water pump will overheat and get stuck due to insufficient voltage. If not careful, the water pump will be burned out and the water flow will also decrease. Due to the above structural reasons, the layout of the machine is relatively loose, the volume is relatively large, and the operation is relatively troublesome. Summary of the Utility Model

[0004] To make up for the above deficiencies, this application provides a pipeline flushing device to solve the problems raised in the above background art.

[0005] To achieve the above object, the technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A pipeline flushing device includes a multi-joint water flow channel main body. A high-pressure pulse output pipe is threadedly connected to the top of one side of the multi-joint water flow channel main body. A check valve I is flange-connected to the bottom end of the multi-joint water flow channel main body. A three-way pipe is flange-connected to the water inlet end of the check valve I. A pressurizing component is installed inside the three-way pipe. A check valve II is installed between the water outlet end of the pressurizing component and the multi-joint water flow channel main body. A pulse component is installed on the top of the other side of the multi-joint water flow channel main body, and a pressure regulating component is installed on the outer wall between the outer wall of the multi-joint water flow channel main body and the outer wall of the three-way pipe.

[0007] Further, the pressurizing component includes a high-pressure water pump, a water pipe I and a water pipe II. The water inlet and outlet ports of the high-pressure water pump are respectively threadedly connected to the opposite ends of the water pipe I and the water pipe II. The outer end of the water pipe I is threadedly connected to the inner end of the three-way joint pipe, and the outer end of the water pipe II is threadedly connected to the water inlet end of the check valve II.

[0008] Further, the pulse component includes a solenoid valve, a check valve III and a high-pressure gas input pipe. The two ends of the solenoid valve are respectively threadedly connected to the opposite ends of the multi-joint water flow channel main body and the check valve III. The outer end of the check valve III is threadedly connected to one end of the high-pressure gas input pipe.

[0009] Further, the pressure regulating component includes a return pipe and an adjustable return valve. The adjustable return valve is installed on the outer wall of the three-way joint pipe. One end of the return pipe is fixedly connected to the adjustable return valve, and the other end is threadedly connected to the bottom of one side of the multi-joint water flow channel main body.

[0010] Further, a water input pipe is threadedly connected to the outer end of the three-way joint pipe.

[0011] Further, a pressure gauge is threadedly connected to the top end of the multi-joint water flow channel main body.

[0012] The utility model has the following beneficial effects:

[0013] 1. By adding multiple check valves and cooperating with a high-pressure water pump and a solenoid valve, the utility model makes the interfaces between the water pump and the tap water share a water input inlet, so that there are only two interfaces, namely the water input inlet and the pulsed high-pressure output port. This simplifies the operation of connecting water pipes. It can work with ordinary tap water or can pressurize at any time by turning on the high-pressure water pump. The use of multiple check valves can prevent water from flowing back and damaging the compressor when using the water pump, tap water or compressor alone without gas supply. The pressure of the water pump can be adjusted by the return pipe and the adjustable return valve. This structure reduces two interfaces and the voltage regulating circuit board, making the whole more compact, more efficient in use and smaller in size. The mechanical return has very good stability and effectively reduces the failure rate.

[0014] 2. By precisely controlling the output volume and pressure of water and gas, the device achieves efficient scouring effect while maximizing the utilization of energy, reducing unnecessary waste, and conforming to the concept of modern energy conservation and environmental protection.

Specific embodiments

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0021] Embodiment:

[0022] Please refer to Figure 1 , a pipeline scouring device, including a multi - joint water flow channel main body 1. The top of one side of the multi - joint water flow channel main body 1 is thread - connected with a high - pressure pulse output pipe 2, and a pressure gauge 10 is installed at the top end; the outer end of the three - head connecting pipe 4 is thread - connected with a water input pipe 9.

[0023] Among them, the multi - joint water flow channel main body 1, as the pipeline connection component of the entire scouring device, is designed as a multi - joint structure, which is convenient for connecting with pipelines or devices in different directions. A reasonable flow channel is designed inside the main body to optimize the water flow distribution and enhance the scouring effect.

[0024] Among them, the high-pressure pulse output pipe 2 is fixedly connected to the top of one side of the multi-joint water flow channel main body 1 by threaded connection. This design not only ensures the stability of the connection but also facilitates subsequent maintenance and replacement. As the key outlet of the entire flushing system, the high-pressure pulse output pipe 2 undertakes the important task of accurately delivering the powerful water flow that has been pressurized and pulse-modulated to the pipeline to be cleaned. The smooth inner wall design inside it reduces the water flow resistance, enabling the high-pressure pulse water flow to impact the inner wall of the pipeline in a more rapid manner, effectively disintegrating and removing impurities such as dirt and sediment adhering to it, thereby achieving efficient cleaning and dredging of the pipeline interior.

[0025] Among them, the water input pipe 9, as the introduction point of the initial water flow, is closely connected to the three-way joint 4, forming the primary channel for the water flow to enter the system. The smooth design of the water input pipe 9 ensures the smooth access of the water source, laying a solid foundation for the subsequent high-pressure flushing process.

[0026] Among them, the pressure gauge 10, as a key component for pressure monitoring, can display the water flow pressure inside the multi-joint water flow channel main body 1 in real time and accurately. This design enables the operator to grasp the working state of the system at any time, ensuring that the flushing process is carried out within the preset safe pressure range. When the pressure abnormally rises or falls, the operator can quickly take measures to adjust, avoiding equipment damage or poor flushing effect.

[0027] Please refer to Figure 1 、 Figure 2 、 Figure 3 , a pipeline flushing device, the bottom flange of the multi-joint water flow channel main body 1 is connected to a check valve I 3, the water inlet flange of the check valve I 3 is connected to a three-way joint 4, a pressurizing component 5 is installed at the inner end of the three-way joint 4, a check valve II 6 is installed between the water outlet end of the pressurizing component 5 and the multi-joint water flow channel main body 1, a pulse component 7 is installed at the top of the other side of the multi-joint water flow channel main body 1, and a pressure regulating component 8 is installed on the outer wall between the outer wall of the multi-joint water flow channel main body 1 and the outer wall of the three-way joint 4; the pressurizing component 5 includes a high-pressure water pump 51, a water pipe I 52 and a water pipe II 53; the pulse component 7 includes an electromagnetic valve 71, a check valve III 72 and a high-pressure gas input pipe 73; the pressure regulating component 8 includes a return pipe 81 and an adjustable return valve 82.

[0028] Among them, the check valve I 3 is installed at the bottom end of the multi-joint water flow channel main body 1, and the selection of this position is crucial. It can not only effectively prevent the reverse flow of water under specific conditions, but also ensure the stability and safety of the entire flushing system. The check valve I 3 is tightly connected to the three-way pipe 4 through flange connection. This connection method not only has high strength, but also has good sealing performance and can withstand the working load under high-pressure environment. When the pressurizing component 5 starts to work, the water flow is quickly pressurized and flows through the check valve II 6 to the multi-joint water flow channel main body 1. At this time, the role of the check valve I 3 is particularly crucial. It uses the weight of the valve flap and the action of fluid pressure to automatically open and close the valve. When the water flow flows from the three-way pipe 4 to the multi-joint water flow channel main body 1, the valve flap is pushed open by the water flow and the valve opens; while when the water flow attempts to flow back from the inner bottom of the multi-joint water flow channel main body 1 through the check valve I 3 into the three-way pipe 4, the valve flap quickly closes under the action of fluid pressure and its own gravity, effectively preventing the occurrence of reverse flow. This function not only protects the upstream equipment from the impact of high-pressure water flow, but also ensures the smooth progress of the flushing operation.

[0029] Among them, the three-way pipe 4, as a key component connecting the multi-joint water flow channel main body 1 and the pressurizing component 5, is made of precision casting or high-quality stainless steel materials, with excellent corrosion resistance and pressure-bearing capacity. Its uniqueness lies in its three-way design, that is, one inlet and two outlets. The inlet end is tightly connected to the water inlet pipe 9 and is responsible for receiving the water flow; while the outlet ends are respectively connected to the inlet ends of the multi-joint water flow channel main body 1 and the pressurizing component 5, realizing the diversion and guidance of the water flow.

[0030] Among them, the pressurizing component 5 is a stable pressurizing system to ensure that sufficient water flow pressure can be provided during the pipeline flushing operation. The high-pressure water pump 51 is the core component of the pressurizing system and is bolted to the predetermined position. The high-pressure water pump 51 is responsible for pressurizing the water flow from the water inlet pipe 9. Its water inlet and outlet ports are respectively provided with threaded interfaces for easy connection with other pipeline components. The water pipe I 52 is the receiving water pipe of the high-pressure water pump 51. One end of the water pipe I 52 is threadedly connected to the water receiving port of the high-pressure water pump 51, and the other end is threadedly connected to the inner end of the three-way pipe 4. The water pipe II 53 is the high-pressure water outlet pipe of the high-pressure water pump 51. One end of the water pipe II 53 is threadedly connected to the water outlet port of the high-pressure water pump 51, and the other end is threadedly connected to the water inlet end of the check valve II 6. Such a design can ensure that the pressurized water flow can smoothly enter the multi-joint water flow channel main body 1. In order to ensure the firm connection and good sealing performance between the components of the pressurizing component 5, threaded connection is adopted as the main connection method. This connection method is not only convenient for installation and disassembly, but also can resist the impact and vibration under high-pressure environment to a certain extent. At the same time, sealing gaskets or sealing adhesives and other sealing materials should be used at the threaded connections to ensure the sealing performance of the connections.

[0031] Among them, the check valve II 6 is installed at the connection between the water pipe II 53 and the multi-joint water flow channel body 1. The selection of this position is based on an in-depth analysis of the water flow path and the potential risk of reverse flow. When the water flows normally in the pipeline, the check valve II 6 is in the open state, allowing the water to flow through smoothly; once the water shows a reverse flow trend, the valve flap of the check valve II 6 will quickly close, cutting off the reverse flow path, thereby protecting the high-pressure water pump 51 upstream from being damaged.

[0032] Among them, the pulse component 7 is installed at the top on the other side of the multi-joint water flow channel body 1, and is used to convert the continuous water flow into a pulsed form to enhance the scouring effect. The solenoid valve 71, as the core control element of the pulse component, is responsible for controlling the on-off of the high-pressure gas. Its two ends are respectively connected to the multi-joint water flow channel body 1 and the opposite end of the check valve III 72 by threads, ensuring the tightness and stability of the connection. The check valve III 72 is installed between the solenoid valve 71 and the high-pressure gas input pipe 73, and its function is to prevent the water flow from flowing back through the check valve III 72. The outer end of the check valve III 72 and one end of the high-pressure gas input pipe 73 are also connected by threads, which is convenient for installation and disassembly. The high-pressure gas input pipe 73 is used to introduce high-pressure gas into the pulse component 7, and is a key component for generating the pulse effect. The other end of it is connected to the high-pressure gas source to provide a stable high-pressure gas supply.

[0033] Among them, the pressure regulating component 8 is respectively installed on the outer walls of the multi-joint water flow channel body 1 and the three-way pipe 4, and is used to monitor and adjust the water pressure in the whole system in real time, ensuring that the scouring process is carried out within a safe and stable pressure range. The return pipe 81, as the pipeline connecting the adjustable return valve 82 and the multi-joint water flow channel body 1, is responsible for leading out part of the water flow from the scouring system to form a return flow. Its material should have good pressure resistance and corrosion resistance to ensure stable operation in a high-pressure water flow environment. The adjustable return valve 82 is installed on the outer wall of the three-way pipe 4, and the opening of the valve can be changed by rotating or adjusting the knob, etc., so as to control the water flow rate through the return pipe 81. The design of the adjustable return valve 82 should be easy to operate and have good sealing performance to ensure the accuracy of adjustment and the stability of the system.

[0034] Working principle of the pipeline scouring device: When cleaning the inside of the pipeline, water flows in from the water input pipe 9, and then directly passes through the check valve I 3. Due to the check valve II 6, the water can only flow out from the high-pressure pulse output pipe 2. Compressed gas enters the multi-joint water flow channel main body 1 from the high-pressure gas input pipe 73 and passes through the check valve III 72 and the solenoid valve 71. The solenoid valve 71 is opened in a wave-like manner, and the released high-pressure gas will push the water in the form of pulses, wave by wave, through the high-pressure pulse output pipe 2 to the pipeline to be cleaned. While scouring the pipeline at high speed, a lot of bubbles of the steam-water mixture will also be generated by the high-pressure gas and water, which will strongly scour the dirt. When some water flows with particularly high pressure are needed, the high-pressure water pump 51 can be directly turned on. Due to the function of the check valve I 3, the suctioned water can only pass through the water pipe I 52. Under the action of the high-pressure water pump 51, the high-pressure water flow enters the inside of the multi-joint water flow channel main body 1 through the water pipe II 53 and the check valve II 6. The high-pressure water flow is pushed from the high-pressure pulse output pipe 2 to the pipeline to be cleaned under the action of the pulse component 7. In this way, the same water input pipe 9 can be used for pressurization work without separately connecting water pumps. When not needed, the high-pressure water pump 51 can be directly turned off. Because of the check valve II 6, the water flow and the high-pressure pulse will not flow back from the high-pressure water pump 51. When using the high-pressure water pump 51, when the working pressure needs to be reduced, the adjustable return valve 82 can be adjusted larger, so that the water flow at the high-pressure end will flow back to the low-pressure end through the return pipe 81, thereby releasing a part of the pressure. This pressure regulation is simple and stable, saving the costly electronic circuit board, sensor, etc. Due to the functions of the check valve I 3 and the check valve II 6 in this new structure, the high-pressure water generated by the high-pressure water pump 51 can only be ejected from the high-pressure pulse output pipe 2.

[0035] It should be noted that the specific model specifications of the check valve I, the check valve II 6, the pressure gauge 10, the high-pressure water pump 51, the solenoid valve 71, the check valve III 72, and the adjustable return valve 82 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0036] The power supply and principle of the high-pressure water pump 51 and the solenoid valve 71 are clear to those skilled in the art and will not be elaborated in detail here.

[0037] For those skilled in the art, it is obvious that this application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of this application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in this application.
