Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a backwashable ball valve with a filtering function. Background Art

[0002] During the pipeline transportation process, the liquid often contains solid impurities. The usual treatment method is to filter the solid impurities in the water. The self-cleaning operation of a separate filtering mechanism is cumbersome.

[0003] In view of the above problems, Chinese Patent with application number 202322810280.X discloses a sewage filtering ball valve. To a certain extent, this device improves the convenience of self-cleaning of the filtering mechanism. However, its disadvantages are also obvious: when the device discharges sewage, the water flow discharges sewage along the normal filtering state water passing direction through the filter screen. The dredging of the filter screen mainly depends on backwashing. If the device wants to backwash its filter screen, it is necessary to rotate the ball valve spool by ninety degrees. After the original water pipe is completely stopped, first discharge the accumulated impurities, and then connect an external water source to the sewage outlet for backwashing. The operation process is very cumbersome; to prevent the filter screen from clogging itself, backwashing should be carried out regularly. Especially, the impurities of this device remain at the bottom of the filter screen, which is more likely to cause the filter screen to clog itself; in view of the above problems, there is currently no corresponding solution. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a backwashable ball valve with a filtering function, which has a simpler structure, flexible assembly and layout, can realize the reciprocating inspection of the detector, and is convenient to use.

[0005] The device includes a ball valve body, and the ball valve body includes a valve sleeve and a valve core;

[0006] The valve sleeve includes a water inlet, a water outlet and a sewage outlet; that is, the valve sleeve is a three-way valve sleeve;

[0007] An inlet pipe and a drain pipe are arranged on the valve core, and the inlet pipe and the drain pipe are communicated with each other, and the arrangement directions are perpendicular to each other;

[0008] A filter body is fixedly arranged in the drain pipe, the filter body is encapsulated by a press-fit bolt, and the press-fit bolt is arranged on the opposite side of the drain pipe outlet; a through hole is also arranged on the press-fit bolt.

[0009] The achieved effect is that in the normal flow state, the inlet pipe faces the water inlet, the drain pipe faces the water outlet, and the water flow is filtered out through the outer wall of the filter body;

[0010] When cleaning the filter element, rotate the valve core so that the drain pipe faces the water inlet and the water inlet pipe faces the sewage outlet. Compared with the filtering state, the water flow directly enters the interior of the filter element to achieve backwashing, and then passes through the filter element, the through hole on the press-fit bolt and the sewage outlet in sequence for sewage discharge.

[0011] The beneficial effects of the present utility model are as follows: Compared with the prior art valve with sewage discharge and filtering functions, the structure of the present utility model is simpler. Especially, the backwashing of the filter element is more convenient, that is, the reverse flushing of the filter element can be achieved by rotating the valve core, which can greatly simplify the flushing operation process of the filter element or the valve.

[0020] Refer to Figure 1 、 Figure 2 and Figure 3 A backwashable ball valve with a filtering function according to the present utility model includes a ball valve main body, and the ball valve main body includes a valve sleeve 1 and a valve core 2;

[0021] The valve sleeve 1 includes a water inlet 11, a water outlet 12 and a sewage outlet 13; that is, the valve sleeve 1 is a three-way valve sleeve;

[0022] The valve core 2 is provided with a water inlet pipe 21 and a drain pipe 22, and the water inlet pipe 21 and the drain pipe 22 are communicated with each other, and the setting directions are perpendicular to each other;

[0023] A filter body 3 is fixedly arranged in the drain pipe 22. The filter body 3 is sealed by a press-fit bolt 23, and the press-fit bolt 23 is arranged on the side opposite to the outlet of the drain pipe 22; a through hole is also arranged on the press-fit bolt 23.
