Fig. 1 is a sectional view of the heat supply flow controller of the present invention, as shown in the figure, the heat supply flow controller includes a first adjusting unit, a second adjusting unit communicated with the first adjusting unit, and a filtering unit. The first adjusting unit comprises a tee ball 1, an adjusting valve rod 2 and a fixed disc 3, and the tee ball 1 is located between the fixed disc 3 and a water inlet 10 of the upper valve body. The adjusting valve rod 2 is connected with the upper part of the tee ball 1, and the middle part and the lower part of the tee ball 1 are provided with a water cavity 4 communicated with the filtering unit and the second adjusting unit. The first regulating unit is used for shutting off or regulating the flow of the water inlet 10. The angle of the tee ball 1 is changed by rotating the adjusting valve rod 2, so that the flow of the water inlet 10 is changed.

The filtering unit comprises a filtering net 5, a filtering cavity 6, a sewage draining outlet 11 and a plug 7, and the filtering cavity 6 communicated with the water passing cavity 4 is internally provided with the cylindrical filtering net 5. The top of the filter screen 5 is positioned in the water through cavity 4, the bottom of the filter screen 5 is connected with a plug 7 at the sewage discharge outlet 11, and the sewage discharge outlet 11 is positioned at the bottom of the filter cavity 6. The filtering unit filters the flow, the three-way ball 1 is closed, the plug 7 is taken down to clean the filtering cavity 6 and replace the filtering net 5.

The second adjusting unit comprises a diaphragm 8, an upper valve flap 9, a movable sleeve 12, a spring 13, a lower valve flap 14, an adjusting cavity 15 and a water outlet 16, wherein two sides of the diaphragm 8 are respectively connected with the upper valve flap 9 and the movable sleeve 12. The upper valve clack 9 and the moving sleeve 12 are internally provided with springs 13, and the other ends of the springs 13 are connected with lower valve clacks 14. The lower valve clack 14 is positioned in the adjusting cavity 15, and the tail end of the adjusting cavity 15 is provided with a water outlet 16. The second regulating unit can automatically regulate the water flow, and under the condition that the water inlet 10 is changed, the constant flow of the water outlet 16 is ensured.

After water enters the tee ball 1 from the water inlet 10, one part of the water enters the first cavity 17 along a gap between the tee ball 1 and the fixed disc 3, and the other part of the water enters the adjusting cavity 15 along the movable sleeve 12 and the upper valve flap 9 in sequence and finally flows out from the water outlet 16. When the pressure inside the first chamber 17 is higher than the pressure inside the second chamber 18 during the water flow, the diaphragm 8 is forced downwards by the pressure difference. The spring 13 is incorporated in compression and when this force is greater than the upward spring force of the spring 13 on the diaphragm 8, the diaphragm 8 moves the upper flap 9 downwards. At this point, the upper flap 9 is closer to the lower flap 14 and the flow decreases, whereas the flow increases.

The middle part of the lower valve clack 14 is circular, and a plurality of tooth blocks 19 are uniformly arranged on the edge of the lower valve clack 14. The diameter of the outer edge of the tooth block 19 is larger than that of the water outlet 16, and the diameter of the outer edge of the tooth block 19 is smaller than that of the inner side wall of the adjusting cavity 15. The arrangement of the toothed block 19 prevents the lower valve clack 14 from moving out of the adjusting cavity 15, and meanwhile, the automatic adjustment of the spring 13, the diaphragm 8 and the upper valve clack 9 on water flow is guaranteed, so that the flow of the water outlet 16 is constant.

One side of the filter screen 5 close to the water inlet 10 is flush with the left end of the water passing cavity 4, and one side of the filter screen 5 close to the fixed disc 3 is flush with the right end of the water passing cavity 4. The filter screen 5 is arranged at the height in the water through cavity 4, so that the water flowing in the water through cavity 4 is completely filtered, and impurities filtered out from the inside of the filter cavity 6 are removed through the sewage outlet 11.

The large-opening end of the fixed disk 3 is communicated with the three-way ball 1, the small-opening end of the fixed disk 3 is internally provided with a movable sleeve 12, and the upper valve flap 9 is matched with one end of the adjusting cavity 15 far away from the water outlet 16. The shape of the fixed disc 3 ensures that the three-way ball 1 can smoothly rotate, and can limit the moving angle and range of the upper valve clack 9, the membrane 8 and the moving sleeve 12.

The end of the diaphragm 8 not connected to the upper valve flap 9 is connected to the flange of the flow controller, ensuring that the diaphragm 8 completely separates the first chamber 17 from the second chamber 18.

The first conditioning unit and the filter unit are located inside a first chamber 17 of the flow controller and the second conditioning unit is located inside a second chamber 18 of the flow controller.

The first cavity 17 and the second cavity 18 are connected by flanges.

A gap communicated with the second cavity 18 is formed between the tee ball 1 and the fixed disc 3, so that a part of water is ensured to enter the first cavity 17 through the gap, and the automatic adjustment of the second adjusting unit is realized.

When the three-way ball is used, the angle of the three-way ball 1 is changed by adjusting the valve rod 2, so that the flow of the water inlet 10 is adjusted. The second adjusting unit automatically adjusts according to the inflow water flow, so that the flow of the water outlet 16 is constant.

Therefore, the utility model adopts the above structure a flow controller for heat supply, the collection is turn-offed, is filtered and is decided flow control as an organic whole, reduces installation space, convenient operation.
