Technical Field

[0001] The utility model relates to the technical field of heat meters, in particular to an anti-blocking heat meter. Background Art

[0002] A heat meter is an instrument for calculating heat. A pair of temperature sensors are installed on the upstream and downstream pipes through which the heat-carrying fluid passes, and a flow meter is installed on the fluid inlet or return pipe. The flow meter emits a pulse signal proportional to the flow rate, and a pair of temperature sensors give analog signals indicating the temperature. The calculator collects signals from the flow and temperature sensors and uses a calculation formula to calculate the heat obtained by the heat exchange system.

[0003] A filter or a filter element is installed in the pipes of existing heat meters to filter out impurities in the water to prevent the impurities in the water from accumulating for a long time and causing blockage in the water pipes and the inside of the meter body. However, when replacing the filter element of the existing heat meter, the main valve needs to be closed before the operation can be carried out, which causes the heat meter to malfunction during maintenance. Impurities dropped from the filter element are also difficult to remove from the heat meter. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides an anti-blocking heat meter, which has the advantages of being able to be maintained without stopping the meter, preventing blockage and facilitating the cleaning of impurities, thereby solving the problems raised by the above-mentioned background technology.

[0008] As an optimal technical solution of the present invention, valve 1 is installed on the outer wall of branch pipe 1, valve 2 is installed on the outer wall of branch pipe 2, and one-way valves are installed on the outer walls of connecting pipe 1 and connecting pipe 2.

[0009] As a preferred technical solution of the present invention, the bottoms of the filter chamber 1 and the filter chamber 2 are both provided with square grooves, and the bottoms of the square grooves on the filter chamber 1 and the filter chamber 2 are both provided with funnels.

[0010] As a preferred technical solution of the present invention, the square groove is close to the water inlet pipe end, the bottom of the funnel is fixedly equipped with a sewage pipe, and the outer edge of the sewage pipe is threadedly connected to a sealing cover.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This anti-blocking heat meter, through the arrangement of filter chamber 1, filter chamber 2, valve 1, valve 2 and a one-way valve, can replace the filter element 1 by closing valve 1, and water flows into the meter body through filter chamber 2. The one-way valve prevents water from entering the filter chamber 1, thereby solving the problem of existing heat meters that require closing the main valve before operating when replacing the filter element, causing the heat meter to be unable to work during maintenance.

[0013] 2. This anti-blocking heat meter sets a funnel under the filter chamber 1 and the filter chamber 2, so that impurities can be retained in the funnel. At the same time, the impurities can be flushed into the funnel and discharged through the sewage pipe, thereby solving the problem of impurities falling from the filter element when the filter element is removed in the existing heat meter. It is difficult to remove the impurities from the heat meter. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 - Figure 5 , a blockage-proof heat meter, including a meter body 1, a data display 2 is fixedly assembled on the top of the meter body 1, a filter chamber 1 5 and a filter chamber 2 6 are provided on the right side of the meter body 1, the inner cavity of the filter chamber 1 5 and the inner cavity of the filter chamber 2 6 are respectively provided with a filter element 14 and a filter element 2 17, the filter chamber 1 5 is connected to the meter body 1 through a connecting pipe 1 3, and the filter chamber 2 6 is connected to the connecting pipe 1 3 through a connecting pipe 2 4, and a water outlet pipe 12 runs through the inner cavity of the meter body 1, water enters the filter chamber 1 5 and the filter chamber 2 6, and the filter elements 14 and 17 in the filter chamber 1 5 and the filter chamber 2 6 filter the water. By utilizing the arrangement of the filter chamber 1 5 and the filter chamber 2 6, when the filter element 14 in the filter chamber 1 5 needs to be replaced, the water can be blocked from entering the filter chamber 1 5. At this time, the water is filtered through the filter chamber 2 6, so that the filter element of this meter can be replaced without closing the main valve.

[0022] In a preferred embodiment, the inner cavity of the filter chamber 15 is provided with a limiting bracket 13, and the filter element 14 is installed on the limiting bracket 13, and the limiting bracket 13 plays a role in fixing the filter element 14. A top cover 15 is installed on the top of the filter chamber 15, and the inner cavity of the filter chamber 26 is provided with a limiting bracket 2 16, and the filter element 2 17 is installed on the limiting bracket 2 16, and the limiting bracket 2 16 plays a role in fixing the filter element 2 17. A top cover 2 18 is installed on the top of the filter chamber 26. By utilizing the arrangement of the filter element 14 and the filter element 2 17, impurities in the water can be filtered, and the meter body 1 can be prevented from being blocked. The space in the filter chamber 15 and the filter chamber 26 is larger than the space in the pipeline, and the filtered impurities can be stored inside. The meter can continue to be used when impurities remain.

[0023] In a preferred embodiment, a branch pipe 9 is installed at the end of the filter chamber 15 away from the connecting pipe 13, and a branch pipe 2 10 is installed at the end of the filter chamber 2 6 away from the connecting pipe 2 4. The ends of the branch pipes 19 and 10 away from the filter chamber 15 are connected to the water inlet pipe 11. The water in the water inlet pipe 11 enters the branch pipe 19 and the branch pipe 2 10 respectively, and then enters the filter chamber 15 and the filter chamber 2 6 respectively, so that water can enter the filter chamber 15 and the filter chamber 2 6, so that the filter chamber 15 and the filter chamber 2 6 can filter the water respectively.

[0024] In a preferred embodiment, a valve 17 is installed on the outer wall of branch pipe 19, a valve 28 is installed on the outer wall of branch pipe 2 10, and a one-way valve 23 is installed on the outer walls of connecting pipe 1 3 and connecting pipe 2 4. The one-way valve 23 prevents the water in connecting pipe 1 3 and connecting pipe 2 4 from flowing back into filter tank 1 5 and filter tank 2 6. By using the setting of valve 1 7 and valve 2 8, valve 1 7 and valve 2 8 block the flow of water in branch pipe 1 9 and branch pipe 2 10. When valve 1 7 is closed, water cannot enter filter tank 1 5, so that filter element 14 in filter tank 1 5 can be replaced. When valve 2 8 is closed, water cannot enter filter tank 2 6, so that filter element 2 17 in filter tank 2 6 can be replaced, thereby improving the rationality of the device.

[0025] In a preferred embodiment, a square groove 19 is provided at the bottom of the filter chamber 1 5 and the filter chamber 2 6 , and a funnel 20 is installed at the bottom of the square groove 19 on the filter chamber 1 5 and the filter chamber 2 6 . By setting the funnel 20, impurities blocked by the filter element 1 14 and the filter element 2 17 can fall into the funnel 20 and be collected by the funnel 20.

[0026] In a preferred embodiment, the square groove 19 is close to the end of the water inlet pipe 11, and a drain pipe 21 is fixedly assembled at the bottom of the funnel 20. The outer edge of the drain pipe 21 is threadedly connected to a sealing cover 22. By opening the sealing cover 22, impurities in the funnel 20 can fall downward through the drain pipe 21, so that the interior of the filter chamber 1 5 and the filter chamber 2 6 can be cleaned without removing the entire meter from the pipeline.

[0027] Working principle: when in use, water enters into branch pipe 1 9 and branch pipe 2 10 through water inlet pipe 11, and then enters filter chamber 1 5 and filter chamber 2 6. At this time, filter cartridge 1 14 and filter cartridge 2 17 in filter chamber 1 5 and filter chamber 2 6 filter the water. The treated water in filter chamber 1 5 enters into meter body 1 through connecting pipe 1 3, and the treated water in filter chamber 2 6 enters into connecting pipe 1 3 through connecting pipe 2 4 and then enters into meter body 1. When filter cartridge 14 in filter chamber 1 5 needs to be replaced, close valve 1 7, and then open top cover 15 to replace filter cartridge 14. At this time, water passes through branch pipe 2 10, filter chamber 2 6 and connecting pipe 2 4 enters the meter body 1 through the connecting pipe 13 and then enters the meter body 1. At this time, the one-way valve 23 on the connecting pipe 13 blocks the water. When the filter element 2 17 in the filter bin 2 6 needs to be replaced, the valve 28 is closed, and then the top cover 218 is opened to replace the filter element 2 17. At this time, the water enters the meter body 1 through the branch pipe 19, the filter bin 15 and the connecting pipe 13. At this time, the one-way valve 23 on the connecting pipe 24 blocks the water. When the filter element 14 and the filter element 2 17 are replaced, impurities will remain in the filter bin 15 and the filter bin 2 6. At this time, the impurities can be discharged by unscrewing the sealing cover 22 under the filter bin 15 and the filter bin 2 6 and flushing.
