Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; for a better understanding of the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product.

Example one

Referring to fig. 1 to 8, the filtering ball valve comprises a valve body 1 and a valve core 2 rotatably installed in the valve body 1, wherein a water inlet pipe and a water outlet pipe communicated with the inside are arranged on two sides of the outer edge of the valve body 1, the filtering ball valve is characterized in that a flushing pipe 1a and a sewage outlet pipe 1b communicated with the inside of the valve body 1 are arranged on the other two sides of the outer edge of the valve body 1, and a filter 3 is arranged in the middle of the valve core 2;

when the valve core 2 is in an initial state, water flowing through the water inlet pipe and the water outlet pipe passes through the filter 3; the dirt in the water flow is filtered by the filter 3.

When the valve core 2 is switched to the self-cleaning state in a rotating mode, the outer edge of the valve core blocks the water inlet pipe and the water outlet pipe, and the middle through hole of the valve core is communicated with the flushing pipe 1a and the sewage outlet pipe 1 b. The rotation angle of the cleaning state is set according to the positions of the flush pipe 1a and the dirt discharge pipe 1b, and generally ninety degrees rotation is adopted. When the rotation is switched to the cleaning state, the water flow enters along the flushing pipe 1a, and then the filter on the valve core 2 is washed, so that the water flow carries dirt to flow out along the dirt outlet pipe 1 b.

The filter 3 comprises a filter cartridge 3a and a compression spiral ring 3b, the filter cartridge 3a can be slidably arranged in the valve core 2 in an inserting mode, a stopper used for stopping one side of the filter cartridge 3a is arranged in the valve core 2, the compression spiral ring 3b is used for stopping the other side of the filter cartridge 3a, external threads are arranged on the outer edge of the compression spiral ring 3b, and internal threads connected with the compression spiral ring 3b are arranged on the inner edge of the valve core 2. By rotating the compression screw ring 3b to remove the compression screw ring 3b, the filter cartridge 3a will not be blocked by the compression screw ring 3b, so that the filter cartridge 3a can be drawn out along the hole of the flush pipe 1a, and it is conceivable that the valve core 2 may also be rotated to be removed along the drain pipe 1b, that is, the filter cartridge 3a is replaced.

The stopper is a plurality of guide sliding strips 4, the length direction of the guide sliding strips 4 is parallel to the axial direction of the hole of the valve core 2, and the open end of the filter cylinder 3a is provided with a strip-shaped groove 3a1 clamped with the guide sliding strips 4. One side of the filter cylinder 3a is limited through the clamping fit of the guide sliding strip 4 and the strip-shaped groove 3a1, and the rotation of the filter cylinder 3a is limited at the same time.

The inner edge of the opening of the filter cartridge 3a is of a bevel structure. Through the oblique angle of the filter cartridge 3a, water flow can better flow through the filter cartridge 3a, impact of the water flow on the filter cartridge 3a is reduced, and the end part of the slide guide strip 4 can be provided with a slope which is coplanar with the oblique angle.

The middle part of the compression spiral ring 3b is provided with a connecting rod 3c. Through being provided with connecting rod 3c for the workman can use anchor clamps to clip connecting rod 3c, and then is convenient for drive to compress tightly spiral ring 3b and rotate dismantles and the installation.

A flat filter net 3a2 for filtering sewage is provided on one side of the filter cartridge 3 a. By using the flat screen 3a2, dirt in water can be filtered.

The valve body 1 can be of a two-half structure, and the two half valve bodies are fixedly connected through a fastener 5. The valve body 1 is of a two-half structure, so that the valve core can be conveniently installed, and when the two half valve bodies are fixedly connected, the middle part of the valve body can be filled with the upper sealing strip.

Example two:

the difference from the first embodiment is that, referring to fig. 7, one side of the filter cartridge 3a is provided with an arc-shaped cover-shaped filter net 3a3 for filtering the contaminated water. By using the arc-cap shaped strainer 3a3, the arc-cap shaped strainer 3a3 can be filled with more dirt, and clogging can occur, that is, the number of times of cleaning the filter cartridge 3a is reduced.

This filter ball valve through rotatory case for case and wash water pipe and go out dirty union coupling, can wash the filter screen through external rivers, need not lift the valve body off the cleanness, practice thrift workman's time, and after the filter screen damages, can will strain a section of thick bamboo and take the filter screen together to change, need not change the valve body, reduce cost.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
