Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laminated filters, in particular to a laminated filter based on three-way ball valve control. Background Art
[0002] The working principle of the laminated filter is mainly based on its unique filter unit structure. This filter is composed of a group of annular reinforced plastic filter discs with grooves or edges. These filter discs are tightly stacked in the unit to form a filter unit that is loose on the outside and tight on the inside. When water flows through these filter discs, the impurity particles in the water are trapped at the intersections formed by the grooves and edges on the filter discs, thereby achieving filtration.
[0003] In the filtering state, water is filtered through the disc from the outside of the filter element. The disc is tightly pressed together by the spring particles and liquid particles. Impurity particles are trapped at the intersection of the discs, and the filtered water flows out of the filter body. When a certain pressure difference or time is reached, the system automatically enters the backwash state. The traditional backwash component uses an equal-diameter grooved tee and a clamped grooved butterfly valve to achieve the backwash function. This component structure requires two manual butterfly valves to be opened and closed for each unit, and this butterfly valve often has high pressure and is not closed tightly, such as Figure 5-7 As shown, the use requirements of the existing laminated filters cannot be met.

When backwashing is needed, the valve handle is turned to adjust the position of the three-way ball valve port, and water will pass through the manual three-way ball valve through the high-pressure water inlet pipe and enter the diaphragm cavity of the three-way valve, thereby opening the water outlet and sewage outlet of the three-way valve, and sewage is discharged through the sewage outlet, thereby solving the sealing problem of traditional butterfly valve fasteners.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1-3 In this embodiment, a laminated filter based on three-way ball valve control is provided, including a laminated filter unit 1, an inlet pipe 2, a drain pipe 5 and an outlet pipe 4. The inlet pipe 2, the drain pipe 5 and the outlet pipe 4 are all reserved with grooved pipe joints 16 for connecting with pipelines. The drain pipe 5 is installed with a plug 6 at the end away from the drain outlet. The outlet pipe 4 is installed with a radial pressure gauge 3 at the end away from the outlet. The bottoms of the inlet pipe 2 and the outlet pipe 4 are respectively provided with an inlet pipe bracket 17 and an outlet pipe bracket 18 for support; the inlet pipe 2 is provided with an axial pressure gauge 13 and an exhaust valve 10 at the end away from the water inlet. The exhaust valve 10 is connected to a double internal thread manual ball valve 11, and the double internal thread manual ball valve 11 is installed and connected to the inlet pipe 2 through an external thread straight pipe joint 12. A Y-type filter 14 is also connected to the water pipe 2 at one end away from the water inlet, and the other end of the Y-type filter 14 is connected to the sewage outlet end of the sewage pipe 5; the laminated filter unit 1 is located above the outlet pipe 4, and the laminated filter unit 1 is connected to the sewage pipe 5 and the water inlet pipe 2 through a three-way sewage valve 15, and the three-way sewage valve 15 is connected to the pipeline interface through a grooved pipe joint 16. The three-way sewage valve 15 adopts a two-position diaphragm three-way valve structure, and a manual three-way ball valve 8 is installed at the diaphragm water inlet position of each three-way sewage valve 15.
