Pressure at the upper end and the lower end of the adjusting block can be changed when water flow passes through the valve body, so that a vacuum area is formed, water flow in the branch pipe and the vertical pipe is driven to flow, a dead water area is prevented from being generated in a water supply system pipeline of domestic water, and bacterium breeding is avoided.

Description

Technical Field

[0001] The utility model relates to the field of water valves, in particular to a running water three-way component. Background Art

[0002] The three-way valve is different from ordinary valves in that it has an outlet at the bottom. When the internal valve core is in different positions, the outlets are different. For example, when the valve core is at the bottom, the left and right outlets are connected. When the valve core is at the top, the right outlet is blocked, and the left and lower outlets are connected. Because the left and right outlets are not on the same horizontal line, when the high-pressure heater is urgently disconnected, the valve is closed and the water supply goes through the bypass.

[0003] Patent CN201820865357.X discloses an instantaneous hot water electric-controlled three-way valve for a fully premixed gas wall-mounted boiler, including a motor, a connector, a valve core assembly and a valve body. The motor is connected to the valve core assembly through a connector. The valve core assembly is arranged in the valve body to switch the two heat medium water outlet ends on and off. The valve body is provided with a water flow channel for domestic hot water. The water inlet port of the water flow channel is connected to the domestic hot water outflow end of the plate heat exchanger, and the water outlet port of the water flow channel is connected to the domestic hot water pipeline. The hot medium water in the hot medium water channel heats the domestic hot water in the water flow channel. Due to the above structure. The modified structure is large in size, complex in structure, and prone to water accumulation and bacteria accumulation. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a running water three-way assembly for living water supply and living hot water in view of the defects of the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A live water three-way assembly comprises a water inlet, a water outlet, a side water outlet and a valve core, wherein a plug is arranged inside the valve core; when the water flow at the water inlet is small, the plug blocks the valve core and the valve core is closed; when the water flow at the water inlet is large, the water flow breaks through the plug, the valve core is opened, and the water flows out from the water outlet or the side water outlet.

[0007] Furthermore, a columnar plug movable groove is provided in the valve core.

[0008] Furthermore, the plug is an umbrella-shaped plug, which includes a plug cover and a plug post, and the plug post moves in a movable groove of the plug.

[0009] Furthermore, the valve core includes a spring, and the spring is sleeved on the movable groove of the plug and the outside of the plug column.

[0010] Furthermore, the water inlet is below the water outlet.

[0011] Furthermore, the water inlet and the water outlet are on the same vertical line to form a straight pipe.

[0012] Furthermore, the side water outlet is located on the side above the valve core.

[0013] Furthermore, the plug blocks the valve core, and when the valve core is closed, the spring is extended; when the water flow flushes the plug and the valve core is opened, the spring is compressed.

[0014] Furthermore, the connection between the side water outlet and the straight pipe is a curved surface connection.

[0015] By adopting the technical solution of the utility model, the beneficial effect of the utility model is that the pressure at the upper and lower ends of the regulating block can be changed in the process of water flowing through the valve body, thereby forming a vacuum area, driving the flow of water in the branch pipe and the riser, avoiding the formation of dead water areas in the water supply system pipelines for domestic water, thereby avoiding the growth of bacteria.

[0025] The specific embodiments of the present invention are further described in conjunction with the accompanying drawings.

[0026] like Figure 1-2 As shown, a live water three-way assembly 1 includes a water inlet 4, a water outlet 5, a side water outlet 6 and a valve core 2, wherein a plug 3 is provided inside the valve core 2; when the water flow at the water inlet 4 is small, the plug 3 blocks the valve core 2, and the valve core 2 is closed; when the water flow at the water inlet 4 is large, the water flow breaks through the plug 3, the valve core 2 opens, and the water flows out from the water outlet or the side water outlet 6.

[0027] A columnar plug movable groove 9 is provided in the valve core 2 .

[0028] The plug 3 is an umbrella-shaped plug 3 , and the umbrella-shaped plug 3 includes a plug cover 7 and a plug post 8 , and the plug post 8 moves in a plug movable groove 9 .

[0029] The valve core 2 includes a spring 10, which is sleeved on the outer side of the plug movable groove 9 and the plug column 8, so that there is a certain resistance when the plug 3 is opened. The plug 3 blocks the valve core 2, and when the valve core 2 is closed, the spring 10 is extended; when the water flow opens the plug 3 and the valve core 2 is opened, the spring 10 is compressed.

[0030] The water inlet 4 is below the water outlet 5. The water inlet 4 and the water outlet 5 are on the same vertical line to form a straight pipe.

[0031] The side water outlet 6 is located on the side above the valve core 2. The side water outlet 6 is connected to the straight pipe at a curved surface.

[0032] The specific usage process of the three-way component 1 is as follows Figure 3-8 As shown, the details are as follows:

[0033] The tee assembly 1 is connected to the vertical pipe 11 and the branch pipe 12, wherein the water inlet 4 of the tee assembly 1 is connected to the vertical pipe 11, one end of the branch pipe 12 is connected to the side water outlet 6 of the tee assembly 1, and the other end is connected to the vertical pipe 11. The branch pipe 12 is also provided with a branch pipe faucet 13.

[0034] like Figure 3 , 4 When the water flow at the water inlet 4 is small, the plug 3 blocks the valve core 2, the valve core 2 is closed, and almost all the water flows to the loop formed by the branch pipe 124. Because the pressure requirement is not reached, the valve body is closed.

[0035] like Figure 5 , 6 As shown, when the water flow at the water inlet 4 is large, the water flow breaks through the plug 3, the valve core 2 opens, and the water flows from the water inlet 4 through the valve core 2 to the water outlet 5, that is, most of the water flows out through the riser 11, and the water flow in the branch pipe 12 circulates according to the Venturi principle.

[0036] like Figure 7 , 8 As shown, when the water flow at the water inlet 4 is large, the water flow rushes through the plug 3, the valve core 2 opens, and the branch pipe faucet 13 is opened, that is, the loop branch pipe 12 faucet uses water, and the water flow at the water inlet 4 flows directly out from the branch pipe faucet 13, and at the same time, the water flow at the water inlet 4 flows through the valve core 2 to the branch pipe 12 faucet 5 and flows out. The water flow is divided into two paths and flows into the branch pipe 12. The branch pipe 12 can be installed with a small diameter pipe, and the pressure loss of the loop branch pipe 12 is low, which is good for the pipe diameter and the use of the booster pump.
