Description

Technical Field

[0001] The utility model relates to the technical field of filter sand cylinders, in particular to a transfer piece used for connecting a multi-directional control valve and a sand cylinder. Background Art

[0002] Sand filters are a common water treatment device, widely used in swimming pools, aquariums, and industrial water treatment. They primarily consist of a tank body and a six-way control valve, used to filter impurities and pollutants from the water. The six-way control valve plays a key role in controlling the direction of water flow and the filtration process.

[0003] In actual production and use, it was discovered that different manufacturers produced different sizes of flanges for connecting the control valves to the sand filter bodies. The center-to-center distance between the connecting studs on the flanges generally varied from 150mm to 250mm, resulting in incompatible six-way control valves from various manufacturers. This significantly inconveniently impacted the production, installation, repair, and replacement of sand filter bodies, increasing maintenance and procurement costs for users. For manufacturers, the lack of universal components increased production costs and inventory management. This also limited the product's application scope, making market development difficult. Utility Model Content

[0004] The utility model provides a transfer piece for connecting a multi-directional control valve and a sand cylinder, which is used for matching connection between the multi-directional control valve and sand cylinders of various specifications.

[0005] A transfer component for connecting a multi-directional control valve and a sand cylinder. The transfer component is a disc-shaped structure. The main body of the transfer component is provided with multiple flange mounting holes corresponding to the positions of the sand cylinder's cylinder flange screw columns and multiple transfer component screw columns corresponding to the positions of the connection holes of the control valve. The flange mounting holes and the transfer component screw columns are staggered.

[0006] The transfer piece of the utility model enables a control valve to be adapted to flanges of different specifications on various existing sand cylinders, and the multi-directional control valve product and the sand cylinder can get rid of the matching restriction.

[0007] The utility model also has the following preferred designs:

[0008] The transfer member of the present invention is provided with a sealing ring groove for installing a sealing ring, so as to improve the connection sealing performance.

[0009] The center distance of the flange mounting holes of the present invention is greater than the center distance of the screw columns of the transfer part.

[0010] The center distance of the flange mounting holes of the present invention can also be smaller than the center distance of the screw columns of the transfer piece. Specifically, the flange size of the sand cylinder can be designed according to the needs.

[0011] The flange mounting hole of the present invention is a countersunk hole, so as to conveniently hide the nut connected to the connecting column on the sand cylinder.

[0012] The beneficial effects of the present invention are:

[0013] The transfer piece of the utility model enables a control valve to be adapted to flanges of different specifications on various existing sand cylinders. The multi-directional control valve product and the sand cylinder can be freed from matching restrictions, thereby improving the application range of the control valve and sand cylinder products and reducing the use cost or production management cost of users and manufacturers.

[0023] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can better understand and implement the technical solution of the present invention.

[0024] like Figures 1 to 6As shown, a transfer component 1 for connecting a multi-directional control valve and a sand cylinder is provided. The transfer component 1 is a disc-shaped structure. The main body of the transfer component 1 is provided with a plurality of flange mounting holes 2 corresponding to the positions of the cylinder flange screw columns 7 of the sand cylinder 6, and a plurality of transfer component screw columns 3 corresponding to the positions of the connection holes of the multi-directional control valve 8. The flange mounting holes 2 and the transfer component screw columns 3 are staggered.

[0025] In one embodiment, see Figure 3 A sealing ring groove 4 for installing a sealing ring 5 is provided on the main body of the transfer member 1 to improve the connection sealing.

[0026] In one embodiment, the center distance of the flange mounting holes 2 is greater than the center distance of the transfer member screw columns 3 .

[0027] In one embodiment, the center distance of the flange mounting holes 2 is smaller than the center distance of the transfer screw columns 3. Specifically, the flange size of the sand cylinder to be connected can be designed according to the need, so that a control valve can be adapted to flanges of different specifications on various existing sand cylinders.

[0028] In one embodiment, the flange mounting hole 2 is a countersunk hole to conveniently hide the nut connected to the connecting column 7 on the sand cylinder 6.

[0029] The above-mentioned implementation examples are only preferred implementation examples of the present utility model, but they cannot be used as limitations on the utility model. Any modifications and improvements based on the concept of the present utility model should fall within the scope of protection of the present utility model. The specific scope of protection shall be subject to the claims.
