Description

Technical Field

[0001] The utility model relates to the technical field of water supply, and in particular to a special pressure-boosting anti-water hammer pipeline arrangement system based on the Tesla valve principle. Background Art

[0002] At present, in the process of home decoration, in order to pursue a higher level of comfort, the diameter of water pipes is often increased, and complex pipes and water-using equipment are arranged, such as installing quick-opening faucets, etc. However, adding equipment to the pipes will increase the burden on the pipes, especially when in use. The water hammer generated is very strong, causing the entire pipe to vibrate, resulting in pipe bursts and pipe leakage, posing a huge safety hazard.

[0003] This includes installing a booster pump when the water pressure is low during the pipeline layout. The existing booster pump will change the pressure environment in the pipeline, greatly enhancing the water hammer phenomenon in the water pipeline. At the same time, due to the unreasonable layout of the pipeline, it is impossible to resist and eliminate the water hammer, causing huge risks.

[0004] When water-using equipment or booster pumps are turned on and the faucet is quickly closed, the kinetic energy of the water in the pipeline will be transmitted in the direction of inertia, generating water hammer waves. When the impact of the water hammer waves is blocked, echoes are formed. Multiple water hammer phenomena will occur when related equipment is turned on and off. The pipeline will vibrate and be under pressure violently, and pipeline collapse and failure often occur, causing losses.

[0005] The existing Chinese utility model patent with application number 202320867178.0 discloses an anti-water hammer pipeline structure, including a Tesla valve pipe, a check valve and a water hammer eliminator. The check valve is located at the water inlet end of the Tesla valve pipe, and the water hammer eliminator is arranged on the Tesla valve pipe. By adopting the above technical scheme, the Tesla valve pipe weakens the kinetic energy of water that has a tendency to flow back after the water hammer effect occurs until it is eliminated, so that the water with a tendency to flow back will not collide with the water with a tendency to move forward in the Tesla valve pipe after the water hammer effect occurs, thereby weakening the vibration of the Tesla valve pipe and the vibration of the entire pipeline. After the water hammer eliminator eliminates most of the energy of the water hammer effect, the check valve can further weaken the water hammer effect at the check valve. However, this scheme still has the following problems:

[0006] 1. Only local functional accessories and pipelines were considered to simulate the direction of Tesla to resist water hammer, but the overall pipeline layout and anti-water hammer effect could not be achieved;

[0007] 2. It is not conducive to practical application. The Tesla principle is embodied on the pipeline, but it cannot be used in actual projects. The bending of the pipeline is not conducive to connection and installation;

[0008] 3. The effect needs to be improved, including the distinction between main pipes and auxiliary pipes. Due to pipeline restrictions, the full-diameter pipeline has limited water hammer resistance. When water hammer occurs, the auxiliary pipe has no obvious effect due to the full-diameter reason;

[0009] 4. There are too many functional accessories in the pipeline, which mainly rely on water hammer absorbers and check valves to eliminate water hammer. The pipeline itself has weak water hammer resistance and cannot achieve the real effect in pipeline arrangement;

[0010] 5. Under the pressurized environment, the pipeline relies on functional accessories to absorb water hammer, the peak value is limited, and there is a risk of failure of the pipeline. Utility Model Content

[0011] In order to solve the above technical problems existing in the prior art, the utility model proposes a special pressure-boosting anti-water hammer pipeline arrangement system based on the Tesla valve principle to solve the problem of large water hammer risk and water shock wave impact in household pipeline layout. The specific technical solution is as follows:

[0012] A boosting special anti-water hammer pipeline arrangement system based on the Tesla valve principle, comprising a main pipeline and a branch pipeline connected to the main pipeline, wherein a boosting pump, a stop valve, a safety valve, and a pressure relief valve are sequentially arranged on the main pipeline, and the branch pipeline comprises a branch main pipeline and a Tesla pipeline structure installed and connected to the branch main pipeline, and the Tesla pipeline structure comprises a return water ring, a water hammer absorber, a short-spacing elbow and two oblique tee assemblies, wherein the upper ends of the main straight pipes of the two oblique tee assemblies are respectively connected to the two ends of the return water ring, and the lower ends of the main straight pipes are connected to the branch main pipeline, and the two ends of the short-spacing elbow are respectively connected to the oblique branches of the two oblique tee assemblies, and the water hammer absorber is installed and connected to the short-spacing elbow.

[0013] Furthermore, there is at least one Tesla pipeline structure arranged on the branch pipeline.

[0014] Furthermore, there is at least one branch pipeline.

[0015] Furthermore, the specifications of the pipes used in the main pipe are greater than the specifications of the pipes used in the branch main pipes.

[0016] Furthermore, the oblique branch pipe is arranged obliquely downward and is integrally connected to the main straight pipe side at an angle of 45 degrees.

[0017] Furthermore, the two oblique tee components are symmetrically arranged.

[0018] Furthermore, the return water ring includes an inlet pipe, a return pipe and an arc-shaped elbow connected between the inlet pipe and the return pipe. The other ends of the inlet pipe and the return pipe are respectively connected to the upper ends of the main straight pipes of the two inclined tee assemblies through connecting pipe fittings, and a water outlet is provided on the arc-shaped elbow.

[0019] Beneficial effect: The invention discloses a special pressure-boosting anti-water hammer pipeline arrangement system based on the Tesla valve principle. In a pressure-boosting pipeline environment, the water hammer is enhanced due to the enhanced water supply pressure. The safety of the entire pipeline is guaranteed under the pressure-boosting condition. At the same time, the water hammer is significantly reduced, the pipeline vibration is reduced, and the water hammer is eliminated without affecting the flow rate. The Tesla valve principle is used in the pipeline layout to increase the pipeline flow rate in the positive direction and reduce the water hammer in the reverse direction. In addition, the effect of single-point single resistance is achieved. Generally speaking, when water hammer occurs, it will cause the entire pipeline to burst and vibrate. This arrangement system can minimize the impact of water hammer while controlling the impact range near a single water point, avoiding the impact on other pipelines and water-using equipment, and achieving partition control to achieve the effect of weak mutual interference. While ensuring water hammer resistance, the entire arrangement system is equipped with an overload function to solve the risk of excessive pressure and pipeline safety. While using the Tesla valve principle to solve water hammer, it supplements and strengthens its safety capability and water hammer resistance, thereby improving the overall water hammer resistance effect and user experience.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 As shown, an embodiment of the present invention provides a pressurized special anti-water hammer pipeline arrangement system based on the Tesla valve principle, including a main pipeline and a branch pipeline connected to each other. All pipe fittings in the pipeline are made of PPR material, which is environmentally friendly and hygienic.

[0024] Among them, the pipe specification used in the main line 5 at the front end of the system is dn25, and a booster pump 1, a stop valve 2, a safety valve 3, and a pressure relief valve 4 are respectively arranged on the main line 5; the booster pump 1 functions as a booster, the stop valve 2 is responsible for the flow control of the entire pipeline, the safety valve 3 is responsible for the pressure safety in the pipeline, and the pressure relief valve 4 is responsible for the supplementary protection against water hammer overload. Through the four functional accessories, the pressure, flow and water hammer damage protection of the main line 5 during the boosting process are achieved.

[0025] The branch pipeline 6 arranged at the back end of the system adopts a Tesla pipeline structure. The branch pipeline 6 is composed of DN20 specification pipelines through connecting pieces. The purpose of connecting pipelines of different specifications is mainly to solve the problem that when the water hammer of the branch pipeline 6 reaches the main pipeline 5, due to the change of pipeline specifications, the increase of the pipeline reduces the impact of the water hammer, and activates the secondary protection of the safety protection of the main pipeline 5. It is understandable that Figure 1 The arrangement of the back end of the system shown may actually include multiple branch pipelines 6 .

[0026] In the embodiment of the utility model, the Tesla pipeline structure designed on a branch pipeline 6 is mainly composed of a pipeline of DN20 specification, a return ring 7, an oblique tee assembly 8, a water hammer absorber 9 and a short-spacing elbow 10. Through the analysis of the Tesla valve principle, when a branch is set in the pipeline and guided back to the main pipeline through the branch pipeline, the transmission of pressure can be hindered by side impact. At the same time, the direction of the side-connected pipeline is adjusted to achieve the effect of unaffected forward flow and reverse obstruction. Experiments show that the effect is best at 45 degrees. Therefore, the oblique branch angle in the oblique tee assembly 8 is 45 degrees, which can achieve the best effect when used and installed; the return ring 7 is at the end of the Tesla pipeline structure. The return ring 7 includes an inlet pipe, a return pipe and an arc-shaped elbow connected between the inlet pipe and the return pipe. The inlet pipe, the return pipe and the arc-shaped elbow are connected between the inlet pipe and the return pipe. The other end of the pipe is connected to the DN20 branch pipes on both sides respectively. The arc elbow is provided with a water outlet. The arc elbow in the return water ring 7 makes the water flow smoother, which can divert the water hammer pressure and reduce the pressure on the pipeline. The oblique tee assembly 8 mainly uses the Tesla valve principle to guide the water hammer pressure. At the same time, due to the factor of the return water ring 7, water hammer is generated in both the water inlet and return water directions. The water hammer pressure at this time is reduced to one-half compared with that of a single pipeline. Therefore, an oblique tee assembly 8 is provided at the water inlet and return water ends for secondary treatment, that is, the two oblique tee assemblies 8 at the water inlet and return water ends are connected by a short-spacing elbow 10, and a water hammer absorber 9 is connected to the short-spacing elbow 10. With this structure, the water hammer can be diverted and then guided to the water hammer absorber 9 for absorption through the pipeline, thereby reducing the pressure on the water hammer absorber 9 and achieving a larger absorption capacity with a smaller peak water hammer absorber.

[0027] In addition, due to the special design of the Tesla pipeline structure, the structure's own resistance and the water hammer absorber 9 cooperate to achieve the effect of a single point single resistance, that is, the branches do not interfere with each other, preventing water hammer conduction damage and causing the entire pipeline system to fail. Moreover, when the Tesla pipeline structure is used in the forward flow direction of the water flow in the system, it does not interfere with the water flow and will only take effect when water hammer occurs. This arrangement system enhances the experience and has the effect of the Tesla valve principle, making the fixed structure longer in life and better in effect. Through the self-resistance of the water flow, mechanical fatigue will not be generated, and the pipeline safety can be guaranteed for a long time without failure.

[0028] When the system of the present invention is running, the booster pump 1 starts to the specified pressure, the stop valve 2 is opened, and the water flows through the dn25 specification pipeline along the way through the safety valve 3 and the pressure relief valve 4, reaches the water branch pipe, that is, the branch pipeline 6, passes through the Tesla pipeline structure, and the oblique tee assembly 8 ensures the normal operation of the water flow without diversion, and flows out through the return water ring 7. Since water hammer is also generated when the booster pump 1 is started, at this time, the safety valve 3 and the pressure relief valve 4 can be effective to offset the initial water hammer, and then the water hammer is diverted through the branch pipeline 6. If it is too large, it will be directly eliminated by the water hammer absorber 9. Under normal circumstances, the water hammer when the pump is started will not be very large.

[0029] When the water is turned off at the end, a large water hammer is generated. When the water hammer is transmitted, the Tesla pipeline structure takes effect, and the water flow is guided into the oblique tee assembly 8 at the corresponding end at the inlet and return ends respectively. The water hammer is eliminated through the impact of the water flow and the water hammer absorber 9. If there is any uneliminated part, it is eliminated through the safety valve 3 and the pressure relief valve 4 in the main line 5. Under normal circumstances, the Tesla pipeline structure of the utility model can completely eliminate the water hammer. Only when the pressure is extremely high will the main line 5 be overloaded and the protection accessory group takes effect.

[0030] When the system is not in operation, since there is still pressure at the water supply point, the multi-pipeline structure designed in this system ensures that the pressure on the pipeline is reduced. In the event of an instantaneous increase in pressure when water is used, the pressure can be evenly distributed through branch pipelines to reduce the impact.

[0031] In summary, the invention discloses a special pressure-boosting anti-water hammer pipeline arrangement system based on the Tesla valve principle. In a pressure-boosting pipeline environment, the water hammer is enhanced due to the enhanced water supply pressure. The safety of the entire pipeline is guaranteed under the pressure-boosting condition. At the same time, the water hammer is significantly reduced, the pipeline vibration is reduced, and the water hammer is eliminated without affecting the flow rate. The Tesla valve principle is used in the pipeline layout, the pipeline flow rate is increased in the positive direction, and the water hammer is reduced in the reverse direction. In addition, the effect of single-point single resistance is achieved. Generally speaking, when water hammer occurs, it will cause the entire pipeline to burst and vibrate. This arrangement system can minimize the impact of water hammer while controlling the impact range near a single water point, avoiding the impact on other pipelines and water-using equipment, and achieving partition control to achieve the effect of weak mutual interference. While ensuring the anti-water hammer, the entire arrangement system is equipped with an overload function to solve the risk of excessive pressure and pipeline safety. While using the Tesla valve principle to solve the water hammer, it supplements and strengthens its safety capability and anti-water hammer capability, thereby improving the overall anti-water hammer effect and user experience.
