Problems solved by technology

[0003] The water hammer effect often occurs in building water supply systems and high-rise water supply systems, which can cause vibrations and generate huge water hammer noises, or burst pipes and leaks, causing water supply interruption accidents, and even flooding the pump room and damaging equipment due to water hammer accidents. , injury to operators and other accidents
[0004] At present, in order to prevent the water hammer effect, some pressure relief devices are often used. The pressure relief device discharges the water in the pipeline to achieve the purpose of pressure relief, but this operation will cause waste of water resources. In view of the above problems, it is necessary to Antimicrobial Pipeline Improvements

Embodiment 1

[0025] An antibacterial PE water supply pipe with anti-water hammer effect, comprising an antibacterial pipe body 1, flanges 14 are respectively connected to both ends of the antibacterial pipe body 1, and the flanges 14 at both ends are convenient for the antibacterial pipe body 1 to be connected to a valve, At the front end of the pump, the inner cavity of the antibacterial tube body 1 is bonded with a matching cylindrical anti-water hammer device 2, the anti-water hammer device 2 is coaxial with the antibacterial tube body 1, and the middle part of the anti-water hammer device 2 is a water passage 5. The inner wall of the water passage 5 is provided with a nano-antibacterial layer 13 made of nano-antibacterial material. The thickness of the nano-antibacterial layer 13 is 0.3 mm. This layer can eliminate Staphylococcus aureus, Staphylococcus albicans, and Candida albicans to a certain extent , Bacillus subtilis, Escherichia coli, Neisseria gonorrhoeae, halophilic bacteria, Ps...

Embodiment 2

[0027]The antibacterial pipe body 1 includes a glass fiber mesh layer 12 and an outermost protective layer 11. When the water flow in the pipe suddenly stops, the subsequent water flow will continue to move forward due to inertia. After the reverse movement, if the confluence of the water flows in the two directions is not in the water flow channel 5, it will cause a large squeeze on the pipe. The glass fiber mesh layer 12 can strengthen the anti-stretch resistance of the antibacterial water pipe body 1, and its strength is not easy When damage occurs, the protective layer 11 is made of PE (polyethylene) material, and the thickness of the protective layer is 2cm. The protective layer 11 effectively protects the pipeline from being damaged by external objects. The nano antibacterial layer 13 formed, the thickness of the nano antibacterial layer 13 is 0.3mm, this layer can eliminate Staphylococcus aureus, Staphylococcus albus, Candida albicans, Bacillus subtilis, Escherichia coli...

Embodiment 3

[0029] The non-return mechanism includes a baffle 9, the area of ​​which is larger than the area of ​​the two ends of the second cavity 4, the baffle 9 is hinged to the two ends of the second cavity 4 through a pin connection, and the connection is located at the top of the baffle 9 In this way, it can be ensured that the baffle 9 and the two ports of the second cavity 4 are always in a closed state when there is no water pressure inside the second cavity 4, and the baffle 9 can effectively prevent part of the water flow in the pipeline from entering the second cavity 4 , to prevent the elastic body 8 in the second cavity 4 from hindering the water flow under normal conditions.

[0030] The right side of the baffle plate 8 is fixed with a sealing ring, which is not shown in the figure, so as to further reduce the internal liquid entering the second cavity 4 under normal conditions. If there is too much water in the second cavity 4, until it is greater than the external pressure...

Abstract

The invention discloses an antibacterial PE water supply pipe with anti-water hammer effect, which includes an antibacterial pipe body, a matching cylindrical anti-water hammer device bonded to the inner cavity of the antibacterial pipe body, and the anti-water hammer device is the same as the antibacterial pipe body Shaft, the middle part of the anti-water hammer device is a water passage, and a plurality of first cavities are distributed in a ring between the water passage and the inner wall of the anti-water hammer device. The left end of the first cavity is closed, and the right end is an opening. In the first cavity, there is a column-shaped slider that slides horizontally. A stainless steel spring is connected between the slider and the left end of the first cavity. There are multiple rings between the first cavity and the water passage. One cavity corresponds to the second cavity, the second cavity is provided with a plurality of bent elastic bodies at intervals, the two ends of the second cavity are provided with non-return structures, and the first cavity is provided with a The pressure relief port is located on the left bottom of the slider. The invention effectively resists the water hammer effect in the pipeline and does not cause waste of water resources.

Description

technical field [0001] The invention relates to the technical field of water pipes, in particular to an antibacterial PE water supply pipe with anti-water hammer effect. Background technique [0002] Generally, antibacterial water pipes are used as the main carrier of drinking water. They are mainly made of non-toxic and environmentally friendly PE materials. Generally, the internal liquid has a certain water pressure. In the pressure piping system, misoperation of the gate or valve, accidental power failure of the pump unit, Accidents such as sudden changes in the water level in and out of the pool, as well as abnormal start and stop of the pump unit, etc., will cause drastic changes in the flow velocity in the antibacterial pipeline, thereby causing momentum exchange, resulting in changes in the impulse of the water body, and causing huge damage to the pipe wall, water pumps, valves and other accessories. Impact force, under the action of water body inertia and compressibi...
