Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a multifunctional valve for a swimming filter device. Background Art

[0002] Water quality management is a vital task in the daily operation of swimming facilities. The water in the swimming pool needs to be continuously filtered to remove impurities and pollutants to ensure the cleanliness and hygiene of the water. To achieve this purpose, a filter device is usually set up in the circulation system of the swimming pool, and the valve is a key component to control the operation of the filter device.

[0003] Traditional valves currently have the following problems: First, they usually only have a single filtering function and cannot perform cleaning operations such as backwashing, which causes the filter material to be easily blocked after a period of use, affecting the filtering effect. Second, traditional valves are usually complex in structure and require the entire valve to be disassembled for cleaning. In addition, the blockage inside the valve cannot be intuitively seen, and frequent manual operations are required, which is not only time-consuming and labor-intensive, but also prone to misoperation.

[0004] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention

[0005] Based on this, the present application proposes a multifunctional valve for a swimming filter device to solve at least one of the above problems. The valve adopts a unique structural design, and realizes the switching of the two working states of filtration and backwashing through the combination of a ball valve and a filter layer. At the same time, the valve is also equipped with a detachable filter element and an openable and closable flap, which is convenient for users to perform cleaning and maintenance operations.

[0006] The technical solution adopted by the present application to solve its technical problems is: a multifunctional valve for a swimming filtering device, comprising: a shell, having a water inlet, a drain and a sewage outlet; a ball valve, comprising a sphere, a valve stem and a handle, wherein there are two ball valves, a first ball valve installed at the water inlet, and a second ball valve installed at the sewage outlet; a filter layer, comprising a filter element and a flap, wherein the flap can be opened and closed on the shell, fixed to the shell by screws and nuts, and the filter element can be disassembled by opening the flap; the filter has two working states, namely, filtering and backwashing. In the filtering state, the first ball valve is opened and the second ball valve is closed, water flows in from the water inlet and is discharged from the drain; in the backwashing state, the first ball valve is closed and the second ball valve is opened, and the water pump installed on one side of the drain works, and water flows in from the drain and flows out from the sewage outlet.

[0007] In some embodiments, a filter cup is mounted in the center of the housing.

[0008] In some embodiments, the filter cup has a plurality of filter holes.

[0009] In some embodiments, the housing is T-shaped.

[0010] In some embodiments, the filter element is fixed to the housing via a groove on the housing.

[0011] In some embodiments, the flip cover is made of transparent acrylic material.

[0012] In some embodiments, a sealing ring is provided between the flip cover and the housing.

[0013] The beneficial effects of the present application are as follows: The valve adopts an easily disassembled filter layer design, making the replacement and cleaning of the filter element convenient and quick. By opening the flap, the filter element can be easily removed and replaced, which greatly simplifies the maintenance process and improves maintenance efficiency. The flap is made of transparent acrylic material, so that the user can intuitively observe the use of the filter element and promptly determine whether the filter element needs to be replaced. The valve is also provided with a filter cup, which cooperates with the filter layer to achieve multi-layer filtration, thereby improving the purity of the water quality. The backwashing achieved by the cooperation of the water pump and the ball valve further prevents the valve from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS
