Description

Technical Field

[0002] In the water treatment field, filtration and softening are common methods. Filtration and softening equipment is widely used in various sectors, especially in industrial applications such as boilers in thermal power plants, cooling circulating water systems in steel mills, paper mills, and pharmaceutical plants, process water in chemical production, pharmaceuticals and food and beverage manufacturing, and rural drinking water improvement projects, all of which require high-flow-rate filtration and softening equipment. Multi-port valves are the core components of filtration and softening equipment; however, due to limitations in large-size ceramic disc manufacturing technology and cost, current production capacities are limited to 40m³ / s. 3 Water filtration and softening equipment with a capacity of over 1,000 liters per hour often uses multiple two-way valves or piston-type multi-way valves to control the water treatment process. Multiple valves have the disadvantages of high cost and complicated installation, while piston-type multi-way valves have the disadvantages of being susceptible to impurities, having a high failure rate, being prone to leakage, and being expensive.

However, to achieve multiple operating states such as softening, backwashing, brine suction, and forward washing in the water treatment process, end-face sealing technology multi-way valves result in complex flow channel structures in the valve plate assembly, leading to high pressure loss.

[0040] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0041] Reference Figure 1 , 2 As shown, a high-flow-rate fluid control valve of this embodiment includes a control valve body 100, an ejector assembly 200, and a drive mechanism 300, and is provided with an inlet 1, a drain 2, an outlet 3, a second water distribution port 4, a first water distribution port 5, and a brine suction port 6. The control valve body 100 (as shown) Figure 3(As shown) There are two valve chambers, a first valve chamber 110 and a second valve chamber 120, and a water inlet 1, a drain outlet 2, a water outlet 3, a second water distribution outlet 4, a first water distribution outlet 5, and an ejector outlet 103. The first valve chamber 110 contains a first fixed valve plate 130, a first movable valve plate 140, and a first valve stem 101, forming a first valve assembly. The first fixed valve plate 130 (as shown) Figure 5 As shown, three through holes are sequentially arranged on the circumference: a first through hole 131, a second through hole 132, and a third through hole 133. A fourth through hole 134 is provided at the center. The first through hole 131 is connected to the drain outlet 2, the second through hole 132 is connected to the inlet 1, and the third through hole 133 is connected to the ejector port 103; the first moving valve plate 140 (as shown) Figure 6 (As shown) A first guiding channel 141 is provided on the circumference at three equal angles. The first guiding channel 141 is connected to the first water distribution port 5. A first moving through hole 142 is provided at the center. The first valve stem 101 passes through the fourth through hole 134 of the first fixed valve plate 130 and the first moving through hole 142 of the first moving valve plate 140. The first fixed valve plate 130 is fixed on the control valve body 100. The first moving valve plate 140 is connected to the first valve stem 101 by a flat or key structure. The drive mechanism 300 drives the first valve stem. When 101 rotates, the first moving valve plate 140 rotates synchronously with the valve stem, so that the first guiding flow channel 141 on the circumference of the first moving valve plate 140 and the three through holes on the circumference of the first fixed valve plate 130 respectively coincide to form a cooperative relationship of different flow channels. In this embodiment, both the first water distribution port 5 and the second water distribution port 4 are provided with connecting parts, which are connected to the inlet and outlet of the filter element tank respectively through the connecting parts. Here, the connecting parts can be connected by conventional flange bolts or by snap-fit.

[0042] The second valve chamber 120 is provided with a second fixed valve plate 150, a second movable valve plate 160, and a second valve stem 102, forming a second valve assembly. The second fixed valve plate 150 (e.g., Figure 7 As shown, three through holes are sequentially arranged on the circumference: a fifth through hole 151, a sixth through hole 152, and a seventh through hole 153. An eighth through hole 154 is located at the center. The fifth through hole 151 is connected to the inlet 1, the sixth through hole 152 is connected to the drain 2, and the seventh through hole 153 is connected to the outlet 3. The second moving valve plate 160 (as shown) Figure 8As shown, a flow channel 161 is provided on the circumference at three equal angles. The flow channel 161 is connected to the second water distribution port 4, and a through hole 162 is provided in the center. The second valve stem 102 passes through the eighth through hole 154 of the second fixed valve plate 150 and the through hole 162 of the second moving valve plate 160. The second fixed valve plate 150 is fixed on the control valve body 100. The second moving valve plate 160 is connected to the second valve stem 102 by a flat or key structure. The drive mechanism 300 drives the second valve stem 102 to rotate. The second moving valve plate 160 rotates synchronously with the second valve stem 102, so that the flow channel 161 on the circumference of the second moving valve plate 160 and the three through holes on the circumference of the second fixed valve plate 150 respectively coincide to form a matching relationship of different flow channels.

[0043] The jetting assembly 200 includes a jetting device 230, an inlet ball valve 210, and a brine suction ball valve 220. It is provided with a jetting inlet 201, a brine suction port 202, and a jetting outlet 203. The jetting inlet 201 is connected to the inlet 1, and the jetting outlet 203 is connected to the jetting outlet 103.

[0044] The softening valve structure described above has the following advantages: In this embodiment, the first fixed valve plate 130 and the first moving valve plate 140 in the first valve chamber 110 and the second valve chamber 120 are combined to form a first valve assembly, and the second fixed valve plate 150 and the second moving valve plate 160 form a second valve assembly. The flow channels of the first fixed valve plate 130 and the second fixed valve plate 150 are designed with a three-part structure, which reduces the number of parts compared to the prior art, resulting in a larger flow channel cross-sectional area for fixed and moving valve plates of the same size. Furthermore, when the flow guide channels of the moving valve plates coincide with the through holes of the fixed valve plates, the flow channel is a straight-through flow channel structure with very low flow resistance. These two points enable the design and manufacture of a high-flow-rate end-face sealed fluid control valve under the conditions of existing special ceramic preparation technology.

[0045] Based on the above structure, the softening valve in this embodiment has the following operating states:

[0046] Figure 9 , 10 As shown in Figure 11 (a case study of water softening treatment).

[0047] In soft water production mode: the first guiding channel 141 is connected to the second through hole 132, and the second guiding channel 161 is connected to the seventh through hole 153. The inlet ball valve 210 and the brine suction ball valve 220 are closed.

[0048] Water enters from inlet 1, flows sequentially through the second through hole 132, the first guiding channel 141, the first water distribution port 5 into the upper part of the resin tank, flows through resin 401 for ion exchange softening treatment, to the bottom of the resin tank, the second water distribution port 4, the second guiding channel 161, the seventh through hole 153, and the softened water flows out from outlet 3.

[0049] Figure 12 , 13 As shown in Figure 14

[0050] Backwashing state: The first guiding channel 141 coincides with and is connected to the first through hole 131 of the first fixed valve plate, and the second guiding channel 161 coincides with and is connected to the fifth through hole 151 of the second fixed valve plate. The inlet ball valve 210 and the brine suction ball valve 220 are closed.

[0051] Water enters from inlet 1, flows sequentially through the fifth through hole 151 of the second fixed valve plate, the second guide channel 161, the second water distribution port 4, and enters the bottom of the resin tank. It then backwashes the resin 401 from bottom to top. The water flows out from the upper part of the resin tank, through the first water distribution port 5, the first guide channel 141, the first through hole 131, and finally from the drain port 2.

[0052] Figure 15 , 16 As shown in Figure 17

[0053] Downstream salt absorption regeneration state: The first guiding channel 141 coincides with and is connected to the third through hole 133 of the first fixed valve plate, and the second guiding channel 161 coincides with and is connected to the sixth through hole 152 of the second fixed valve plate. The inlet ball valve 210 and the salt absorption ball valve 220 are open.

[0054] Water enters from inlet 1 and flows sequentially through inlet ball valve 210 – ejector 230 – generating negative pressure. Regenerated brine is drawn into ejector 230 through brine suction ball valve 220 and mixed evenly with the inlet water – ejector outlet 203 – ejector port 103 – third through hole 133 – first guide channel 141 – first water distribution port 5 enters the upper part of the resin tank – flows through resin 401 for ion exchange regeneration treatment – ​​bottom of resin tank – second water distribution port 4 – second guide channel 161 – second fixed valve plate sixth through hole 152 – water flows out from drain port 2.

[0055] Slow wash mode: The engagement state of the moving and stationary valve plates in both valve chambers is the same as in the co-current brine regeneration mode. The inlet ball valve 210 is open, and the brine suction ball valve 220 is closed. The water flow direction is the same as in the co-current brine regeneration mode, the difference being that the brine suction ball valve 220 is closed, and no more regenerated brine is being drawn in.

[0056] Figure 18 , 19 As shown in Figure 20

[0057] Positive flushing status:

[0058] The first guiding channel 141 coincides with and is connected to the second through hole 132 of the first fixed valve plate, and the second guiding channel 161 coincides with and is connected to the sixth through hole 152 of the second fixed valve plate. The inlet ball valve 210 and the brine suction ball valve 220 are closed.

[0059] Water enters from inlet 1, flows sequentially through the second through hole 132 of the first fixed valve plate, the first guide channel 141, the first water distribution port 5, enters the upper part of the resin tank, flows through resin 401 for positive rinsing from the first to the second, the bottom of the resin tank, the second water distribution port 4, the second guide channel 161, the sixth through hole 152 of the second fixed valve plate, and the water flows out from the drain port 2.

[0060] Operating status for softened water / salt tank replenishment:

[0061] The engagement state of the moving and stationary valve plates in both valve chambers is the same as that during soft water production. The inlet ball valve 210 and the brine suction ball valve 220 are open. In this state, soft water production is carried out while simultaneously replenishing the brine tank. Soft water is replenished to the brine tank through the opening of the inlet ball valve 210 and the brine suction ball valve 220. A portion of the water flows from the inlet through the inlet ball valve 210, the ejector 230, and the brine suction ball valve 220, flowing into the brine tank. Once the required replenishment volume is reached, the inlet ball valve 210 and the brine suction ball valve 220 are closed.

[0062] In this embodiment, by setting the drive mechanism 300 to turn off the functions of co-current salt absorption and regeneration, slow washing, and salt tank water replenishment, while retaining the functions of water production, backwashing, and forward washing, the water filtration function can be achieved by using an external filter tank.

[0063] In summary, the high-flow-rate fluid control valve of this embodiment uses a combination of a first valve assembly and a second valve assembly to achieve switching of at least four working states required for softened water. Compared with the structure of a single valve assembly in the prior art, it has fewer equal parts, and the flow channel cross-sectional area of ​​the fixed valve plate and the moving valve plate of the same size is larger, and the flow rate is correspondingly larger.

[0064] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
