[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 This utility model provides a technical solution: a combination device of a small-diameter water meter and a check valve, including a housing 100, a water meter unit 200 disposed on the upper part of the housing 100, and a sealing unit 300 disposed on the upper part of one side of the housing 100. The water meter unit 200 includes an impeller rotation area 210 opened inside the housing 100, and an impeller 211 is rotatably disposed inside the impeller rotation area 210. When water flows into the impeller rotation area 210, the water will contact the impeller 211 and generate... The impact further causes the impeller 211 to rotate. The two ends of the housing 100 are respectively provided with tubular threaded interfaces 110, which facilitate the connection of the whole device to the pipeline, thereby facilitating the flow of water. A water meter counting area 220 is provided above the impeller rotating area 210, and a water meter dial area 230 is provided above the water meter counting area 220. Through the contact between the water meter counting area 220 and the water meter dial area 230 and the impeller 211, the water volume can be counted and statistically analyzed.

[0025] See Figure 1 , Figure 3 In a preferred embodiment, the water flows from the threaded interface 110 to the sealing unit 300 and then out through the threaded interface 110 at the other end. When installing the whole device, the sealing unit 300 must be set at the water outlet end of the whole device to prevent water flow from being blocked due to incorrect installation direction.

[0026] The sealing unit 300 includes a valve disc 310 fixedly installed on the inner wall of the housing 100. A sealing groove 311 is provided on the inner side of the valve disc 310. A stainless steel baffle plate 312 is inserted into the sealing groove 311. The valve disc 310 and the stainless steel baffle plate 312 can reduce the pressure drop and extend the service life through hardening treatment.

[0027] The valve disc 310 is circular, and the stainless steel baffle 312 is also circular with an opening at its center. Water flows through this opening. A sealing ring 320 is provided at the end of the stainless steel baffle 312 away from the housing 100. The sealing ring 320 ensures a stable connection at the joint of the stainless steel baffle 312. The stainless steel baffle 312 is connected to the sealing groove 311 and sealed with a rubber ring. The rubber sealing ring reduces the tightness of the connection between the stainless steel baffle 312 and the sealing groove 311, preventing leakage and reducing liquid backflow.

[0028] See Figures 1-3 In a further preferred embodiment, the sealing unit 300 further includes a rocker chain 330 disposed on the inner wall of the housing 100. One end of the rocker chain 330 is fixedly mounted with a rocker arm 331. A sealing plate 3311 is fixedly mounted on the end of the rocker arm 331 facing the stainless steel baffle plate 312. The surface area of ​​the sealing plate 3311 is larger than the surface area of ​​the circular opening of the stainless steel baffle plate 312. The sealing plate 3311 is circular. When the water flows back, the water will contact the sealing plate 3311 and generate force, which will further enable the rocker chain 330 to rotate at a certain angle, pushing the sealing plate 3311 and the rocker arm 331 towards the sealing ring 320, thereby blocking the water flow channel and preventing the water from flowing back.
