Due to the pipe material, water quality and other factors, pollutants such as scale and rust may exist in the water in the delivery pipes. Therefore, it is necessary to install a filtering and decontamination device in the heating pipes to remove pollutants.

[0003] In the prior art, a filter screen cleaner device is usually installed in the heating pipeline for filtering. The cleaner in the prior art is usually a separate accessory and needs to be connected to a control valve for control. On the one hand, it increases the installation process, resulting in low installation efficiency and high cost. On the other hand, since the cleaner and valve usually come from different manufacturers and the interface sizes are inconsistent, it is necessary to add an adapter or transition connecting pipe for connection and installation, resulting in complicated pipeline connection, increased cost and reduced reliability. In addition, the cleaner in the prior art mostly uses manual sewage discharge, which is inconvenient to use and has a low degree of intelligent automation.

[0004] In order to solve the above problems, the utility model provides an automatic sewage discharge mechanism for an intelligent heating system. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic sewage discharge mechanism for an intelligent heating system, which can realize automatic sewage discharge and has the characteristics of simple structure, easy installation, easy use and strong practicality.

A first joint is provided on one side of the valve ball cavity, and a second joint is provided on one side of the filter element cavity. The top of the filter element cavity is open and is detachably connected to a conical sub-shell. A floating part is provided in the sub-shell, and an exhaust port is provided on the top of the sub-shell.

[0010] A valve seat gland is provided between the first joint and the main housing.

[0011] The side wall of the filter element cavity is provided with a first sewage discharge port, and the bottom surface is provided with a second sewage discharge port.

[0012] The volume of the filter element cavity is larger than the volume of the valve ball cavity.

[0013] The bottom of the filter element cavity is provided with an inverted conical sedimentation cavity, and inclined arc-shaped protrusions are arranged in the sedimentation cavity.

[0014] The communication port between the valve ball cavity and the filter element cavity is located at the inner tangent of one side of the filter element cavity.

[0015] The communication port is inclined downward at a certain angle.

[0016] The communication port is located in the lower part of the filter element cavity, and the second joint is located in the upper part of the filter element cavity.

[0017] The filter element includes upper and lower parts. The upper part of the filter element is arranged in the upper part of the filter element cavity corresponding to the second joint, and the lower part of the filter element is arranged in the lower part of the filter element cavity corresponding to the communication port.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model. Embodiment

[0031] Refer to Figures 1-4 , an automatic sewage discharge mechanism for an intelligent heating system, including an integrated microbubble filtration ball valve 10 provided on a water supply pipeline. The sewage discharge port of the integrated microbubble filtration ball valve 10 is communicated with a return water pipeline 30 through a sewage discharge pipeline 20, and an electric control valve 40 is provided on the sewage discharge pipeline 20. The electric control valve 40 in this embodiment is preferably exemplified by an electric ball valve, which is a second ball valve. It includes a ball valve and a driving motor 404 linked to the ball valve. The valve body of its ball valve is fixedly connected to the fixed seat 403 of the driving motor 404. The driving motor 404 is fixed on the fixed seat 403. Its valve ball 401 is linked to the driving motor 404 through a valve rod 402. The driving motor 404 is controlled by an intelligent management system, and the intelligent management system is a prior art and will not be elaborated in this application.

[0032] The integrated microbubble filtration ball valve includes a main housing 1. Inside the main housing 1, there are a valve ball cavity 1-1 and a filter element cavity 1-2 that are interconnected. The volume of the filter element cavity 1-2 is larger than that of the valve ball cavity 1-1. A valve ball is arranged in the valve ball cavity 1-1. The valve stem of the valve ball extends out of the top of the valve ball cavity 1-1 and is connected with a handle 2. On one side of the valve ball cavity 1-1 away from the filter element cavity 1-2, there is a first joint 3. Between the first joint 3 and the valve ball cavity 1-1 of the main housing 1, there is a valve seat gland 4. The valve seat gland 4 is threadedly connected with the main housing 1. At one end of the valve seat gland 4 away from the valve ball, there is an annular groove, and a sealing ring 5 is arranged in the annular groove. The first joint 3 and the valve seat gland 4 are sealed and connected.

[0033] A filter element 9 is arranged in the filter element cavity 1-2. On one side of the filter element cavity 1-2 away from the valve ball cavity 1-1, there is a second joint 6. The top of the filter element cavity 1-2 is open and is detachably connected with a conical sub-housing 7. An exhaust mechanism is arranged in the sub-housing 7. The exhaust mechanism includes a floating member 8. At the top of the sub-housing 7, there is an exhaust port 7-1. An exhaust valve is arranged in the exhaust port 7-1. The floating member 8 is linked with the exhaust valve (not shown in the figure). 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 clamping groove with a groove structure. One end of the exhaust valve plugs the cavity of the exhaust port 7-1, and the other end is inserted into the clamping groove space of the floating member 8. The floating member 8 can move up and down along the inner cavity of the sub-housing 7, so as to drive the exhaust valve to reciprocate elastically up and down. When there are microbubble gases in the cavity of the sub-housing 7, the gases float to the upper end of the cavity of the sub-housing 7, pressing down the water in the pipeline and the floating member 8, causing the floating member 8 to move downward and driving the exhaust valve to move downward elastically deforming, opening the exhaust port 7-1. Let the gas in the cavity be discharged from the exhaust port 7-1 out When the gases in the sub-housing 7 are exhausted, at this time, 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.

[0034] On the side wall of the filter element cavity 1-2, there is a first sewage discharge port 1-3, and on the bottom surface, there is a second sewage discharge port 1-4. The second sewage discharge port 1-4 discharges the sewage to the return water pipeline 30 through a sewage discharge pipeline 20. The first sewage discharge port 1-3 is convenient for use during maintenance and repair.

[0035] A third ball valve 50 operated manually is provided on the return water pipeline 30. During use, the microbubble filtration integrated ball valve 10 and the third ball valve 50 are in an open state all the time. After the heating hot water passes through the microbubble filtration integrated ball valve 10 on the water supply pipeline, it flows through the floor heating or wall heating and then returns through the return water pipeline 30. The microbubble filtration integrated ball valve 10 filters out impurities and dirt. The intelligent management system controls the driving motor 404 to open the second ball valve regularly or irregularly, such as discharging once a day or the intelligent management system monitors the water quality in the pipeline and automatically controls the action of the driving motor 404 according to the change of water quality, and discharges the filtered impurities and dirt into the return water pipeline 30 for discharge, so as to realize automatic sewage discharge and improve the stability, reliability and service life of the user's heating system.

[0036] As a specific implementation manner of an automatic sewage discharge mechanism for an intelligent heating system provided by the present utility model, please refer to Figures 5 to 6 , a conical sedimentation cavity 1-5 is provided at the bottom of the filter element cavity 1-2. Inclined arc-shaped protrusions 1-5-1 are arranged in the sedimentation 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 of one side of the filter element cavity 1-2 and inclines downward at a certain angle, so that the water flow entering the filter element cavity 1-2 forms a spiral eddy current, and cooperates with the inclined arc-shaped protrusions 1-5-1 to facilitate the downward deposition and separation of impurities in the water. The second sewage discharge port 1-4 is arranged at the lower end of the sedimentation cavity 1-5, and then the separated impurity sewage is discharged to the return water pipeline 30 through the sewage discharge pipeline 20 for discharge.

[0037] As a specific implementation manner of an automatic sewage discharge mechanism for an intelligent heating system provided by the present utility model, please refer to Figure 7 , the communication port between the valve ball cavity 1-1 and the filter element cavity 1-2 is located at the lower part of the filter element cavity 1-2, and the second joint 6 is located at the upper part of the filter element cavity 1-2. The filter element 9 includes upper and lower parts. The upper part of the filter element is arranged at the upper part of the filter element cavity 1-2 corresponding to the second joint 6, and the lower part of the filter element is arranged at the lower part of the filter element cavity 1-2 corresponding to the communication port between the valve ball cavity 1-1 and the filter element cavity 1-2. The lower part of the filter element is sparser than the upper part of the filter element, so that after the water flow realizes spiral eddy current, turbulent flow, cutting and filtration at the lower part of the filter element cavity 1-2, and then passes through the upper part of the filter element for secondary filtration, it is output from the second joint 6.

[0038] The above are the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
