Description

Technical Field

[0001] The invention relates to the technical field of water supply valves for pipeline systems, and in particular to a dynamic circulating water flow valve. Background Art

[0002] Hotels, guesthouses, saunas, spas, factory dormitories, residential quarters, villas, flats, high-end clubs and other places that need water all need to use water pipes and valves to access the water flow. In the traditional water supply pipeline system, because the pipes are connected in parallel, some water points that are not often used will form "dead water sections". "Dead water sections" are sections of water that have not flowed in the water supply pipeline for a long time. Such "dead water sections" are one of the necessary conditions for the production of Legionella: if the water flow is stagnant for more than 6 hours, and the water flow temperature in the "dead water section" is between 25℃-55℃, Legionella can multiply in large numbers.

[0003] For example, in daily use, in an average household, the amount of dead water accumulated in the water supply pipe is about 80L, which is equivalent to the amount of 4 barrels of mineral water. The Legionella generated in these dead water sections will multiply in large numbers, not only corroding the pipes, but also polluting the water in the water supply pipes, affecting the hygiene and safety of the water, and even endangering people's lives and health. Traditional ordinary valves cannot achieve circulation in the pipes, making it difficult to effectively guarantee the water quality in the water pipes.

[0004] CN110206914A discloses a dynamic circulation valve, including a valve body, wherein the upper and lower ends of the valve body are respectively provided with a water inlet and a water outlet, the side wall of the valve body is fixedly connected with a first connecting pipe and a second connecting pipe, the inner cavity side wall of the valve body is provided with a mounting block, the side wall of the mounting block is provided with a mounting groove penetrating the valve body, the outer side wall of the mounting block is screwed with a rotating ring, the inner side wall of the rotating ring is screwed with an adjusting ring, a guide rod penetrating the adjusting ring is fixedly installed in the mounting groove, and the inner side wall of the mounting ring is equipped with an adjusting block. Although the device can realize the dynamic circulation of water flow, it adopts the combination of a valve body and a rotating ring, and the rotating ring uses a screwed adjusting ring. First, the overall structure is too complicated and the process cost is high. Second, the valve body is a split design, which is easy to hide dirt and dirt, and long-term use is not conducive to water source cleaning.

For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] like Figure 1-3 As shown, a circulating water flow valve includes a valve body 100, and a water inlet 101 and a water outlet 102 are respectively provided at both ends of the valve body 100. The water inlet 101 is connected to a water outlet pipe 104, and the water outlet 102 is connected to a water inlet pipe 103; the outer walls of the water inlet 101, the water outlet 102, the water inlet pipe 103 and the water outlet pipe 104 are all provided with scale bars.

[0035] As attached Figure 5-7As shown, a base 105 is provided between the inner cavity of the valve body 100, the water inlet pipe and the water outlet pipe. The base is a funnel structure or a columnar structure with a through hole 106 in the middle. The base is used to place the one-way valve and limit the one-way valve. The through hole 106 is provided so that the valve body 100 is a through structure; the base 105 is located between the water inlet pipe 103 and the water outlet pipe 104, and a water flow direction schematic arrow is provided on the valve body 100, and the water inlet pipe 103 and the water outlet pipe 104 are respectively provided with water flow direction schematic arrows. The valve body 100, the base 105, the water inlet pipe 103 and the water outlet pipe 104 are integrally formed of PPR material.

[0036] A one-way valve 200 is installed on the base 105 of the valve body 100. The one-way valve 200 includes a top seat 201, a base 202 and a valve core 203. The top seat 201 is a cylindrical structure. A hollow groove 204 is provided in the middle of the top seat 201. The base 202 is fastened and fixed to the top seat 201. A guide groove 205 is provided inside the base 202. A baffle 206 is fixed on the outer periphery of the base 202. The top seat 201 and the base 202 are coaxial and consistent with the length direction of the baffle 206; the outer wall of the top seat 201 and the outer wall of the baffle 206 are both in contact with the inner wall of the valve body 100; the inner diameter of the through hole 106 is smaller than the inner diameter of the hollow groove 204; there are no less than 2 baffles 206.

[0037] The valve core 203 is installed at the bottom of the hollow groove 204 of the top seat 201. The valve core 203 is a truncated cone structure. The maximum outer diameter of the valve core 203 is larger than the inner diameter of the hollow groove 204. A guide rod 207 is fixed to the bottom of the valve core 203. The other end of the guide rod 207 extends into the guide groove 205. A spring 208 is sleeved on the guide rod 207. One end of the spring 208 is fixed to the bottom of the valve core 203, and the other end is sleeved and fixed to the guide groove 205. The valve core 203 can move in the axial direction of the guide rod 207, thereby controlling the opening and closing of the valve body 100.

[0038] An annular groove 209 is provided around the outer wall of the top seat 201, and a sealing ring 210 is installed in the annular groove 209. The sealing ring 210 and the inner wall of the valve body 100 are interference sealed; a sealing ring 211 is provided on the inner wall of the top seat 201, and the valve core 203 rests on the sealing ring 211 to shut off water.

[0039] An annular groove 107 is provided on one side of the inner wall of the valve body 100 close to the base 105; a buckle tooth 212 is provided on the outer wall of the base 202. After the one-way valve 200 is installed, the buckle tooth 212 is located in the annular groove 107, so that the one-way valve 200 is combined with the valve body 100, and the sealing between the top seat 201 and the inner wall of the valve body 100 is also achieved.

[0040] During installation, place the one-way valve 200 into the valve body 100 from the water outlet 102 so that the valve core faces the water inlet 101, and the buckle tooth 212 of the one-way valve is inserted into the annular groove 107 on one side of the base 105. The installation is simple, does not require other tools, and is convenient and efficient.

[0041] When in use, the device is installed in the water supply pipe system of different floors. When water flows through the water inlet 101, the water flow generates pressure on the valve core 203, and the valve core 203 moves toward the base 202 along the axis of the guide rod 207, thereby compressing the spring 208 and the valve core 203 moves away from the top seat 201. Then, the water flow can pass through the top seat 201 and flow out from the valve core, between the top seat and the base, and the outer wall of the base. The greater the water pressure, the greater the movement distance of the valve core, and the greater the water flow. Since the one-way valve changes the pressure difference of the water flow through the valve body , so that a pressure difference is formed at the connection between the water inlet pipe 103 and the valve body 100, so that the water in the water inlet pipe 103 can flow into the valve body, and the water in the water outlet pipe 104 flows into the domestic water pipeline and then flows out through the water inlet pipe 103, thereby forming a cycle, so that water flow is formed in the water pipeline, avoiding water retention in the pipeline, and the hygiene is revolutionized, ensuring that the water in the pipeline is always fresh, and Legionella in the pipeline system is not easy to breed, thereby improving people's quality of life and providing a healthy and hygienic water experience.

[0042] When the water outlet is closed, the valve core 203 is acted upon by a balancing force, and the spring 208 provides an upward supporting force, so that the valve core 203 presses against the second sealing ring 211 to shut off the water, and the pipeline is closed.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
