[0025] 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.

[0026] Example

[0027] See also Figure 1 and 2 A microbubble filtration integrated ball valve comprises a main shell 1, wherein the main shell 1 has a valve ball chamber 1-1 and a filter element chamber 1-2 which are interconnected, the volume of the filter element chamber 1-2 is larger than the volume of the valve ball chamber 1-1, a valve ball is arranged in the valve ball chamber 1-1, a valve stem of the valve ball extends out of the valve ball chamber 1-1 and is connected to a handle 2 at the top, a first joint 3 is arranged on the side of the valve ball chamber 1-1 away from the filter element chamber 1-2, a valve seat gland 4 is arranged between the first joint 3 and the valve ball chamber 1-1 of the main shell 1, the valve seat gland 4 is threadedly connected to the main shell 1, an annular groove is arranged at one end of the valve seat gland 4 away from the valve ball, a sealing ring 5 is arranged in the annular groove, and the first joint 3 and the valve seat gland 4 are sealed.

[0028] A filter element 9 is arranged in the filter element cavity 1-2, and a second joint 6 is arranged on the side of the filter element cavity 1-2 away from the valve ball cavity 1-1. The top of the filter element cavity 1-2 is open and detachably connected with a conical sub-shell 7. An exhaust mechanism is arranged in the sub-shell 7, and the exhaust mechanism includes a floating member 8. An exhaust port 7-1 is arranged at the top of the sub-shell 7, and an exhaust valve is arranged in the exhaust port 7-1. The floating member 8 is linked with the exhaust valve. When the air pressure in the cavity reaches a certain level, the excess air can be exhausted through the floating member 8 and the exhaust port 7-1. Specifically, one end of the floating member 8 is a floating block, and the other end is a card slot with a groove structure. One end of the exhaust valve is blocked in the cavity of the exhaust port 7-1, and the other end is inserted in the card slot space of the floating member 8. The floating member 8 can move up and down along the internal cavity of the sub-shell 7, thereby driving the exhaust valve to elastically deform up and down. When there is microbubble gas in the cavity of the auxiliary shell 7, the gas floats to the upper end of the cavity of the auxiliary shell 7, pressing the water in the pipeline and the floating element 8 downward to move the floating element 8 downward and drive the exhaust valve downward to elastically deform, opening the exhaust port 7-1, and allowing the gas in the cavity to be discharged from the exhaust port 7-1. When the gas in the auxiliary shell 7 is discharged, the pressure in the cavity drops, and the water in the cavity drives the floating element 8 to float upward, causing the exhaust valve to elastically recover and block the exhaust port 7-1.

[0029] The side wall of the filter element cavity 1-2 is provided with a first sewage outlet 1-3, and the bottom surface is provided with a second sewage outlet 1-4. The second sewage outlet 1-4 discharges sewage to the return water pipeline, and the first sewage outlet 1-3 is convenient for use during inspection and maintenance.

[0030] As a specific implementation of the micro-bubble filtration integrated ball valve provided by the utility model, please refer to Figure 3 to Figure 4The bottom of the filter element cavity 1-2 is provided with an inverted cone-shaped sinking cavity 1-5, and an inclined arc-shaped protrusion 1-5-1 is arranged in the sinking cavity 1-5. The communication port between the valve ball cavity 1-1 and the filter element cavity 1-2 is located at the inner tangent line of one side of the filter element cavity 1-2 and is inclined downward at a certain angle, so that the water flow entering the filter element cavity 1-2 forms a spiral vortex, and cooperates with the inclined arc-shaped protrusion 1-5-1 to facilitate the downward sedimentation and separation of impurities in the water. The second sewage outlet 1-4 is set at the lower end of the sinking cavity 1-5, and then the separated impurities are discharged.

[0031] As a specific implementation of the micro-bubble filtration integrated ball valve provided by the utility model, please refer to Figure 5 The connecting port between the valve ball chamber 1-1 and the filter element chamber 1-2 is located at the lower part of the filter element chamber 1-2, and the second joint 6 is located at the upper part of the filter element chamber 1-2. The filter element 9 includes an upper and a lower part. The upper filter element corresponds to the second joint 6 and is arranged at the upper part of the filter element chamber 1-2. The connecting port between the valve ball chamber 1-1 and the filter element chamber 1-2 corresponding to the lower filter element is arranged at the lower part of the filter element chamber 1-2. The lower filter element is sparser than the upper filter element, so that the water flow can realize spiral vortex, turbulence, cutting and filtration in the lower part of the filter element chamber 1-2, and then pass through the upper filter element to realize secondary filtration before being output from the second joint 6.

[0032] When the utility model is used for pipeline connection and installation, it is only necessary to connect the pipeline to the two joints. The installation is simple and efficient. During use, the ball valve is connected to the water supply pipeline, and the second sewage outlet 1-4 can be connected to the return pipeline. The filtered impurities can be directly discharged to the return pipe for discharge, thereby improving the stability, reliability and service life of the user's heating system.

[0033] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
