Description

Technical Field

[0001] The utility model relates to the technical field of water meter equipment, in particular to an anti-blocking water meter. Background Technique

[0002] With the acceleration of the urbanization process, the construction of the water supply system is becoming increasingly perfect. As an important tool for measuring the water consumption of residents, the performance of the water meter directly affects the stability of the water supply system and the water use experience of users. However, after long-term use, scale and other impurities are likely to accumulate inside the water meter. These problems will cause blockage inside the water meter, thus affecting the normal operation of the water meter and even causing problems such as inaccurate measurement.

[0003] In the traditional water meter design, in order to prevent scale and impurities from entering the inside of the water meter, a filter pad with a filter screen is usually set at the water inlet end or the water outlet end of the water meter. Although this method can alleviate the problem of impurities entering the inside of the water meter to a certain extent, it has obvious defects. First of all, due to the small filtering area of the filter pad, it is easily blocked by impurities and the filter pad needs to be frequently removed to remove impurities. Secondly, each cleaning requires using tools to disassemble the joints or the plugs of the filter screen. This process is not only cumbersome but also increases the maintenance cost and time consumption. When a large amount of scale is generated inside the water meter, it will cause a local pressure increase inside the pipeline. On the one hand, it will have an adverse effect on the components inside the water meter, and on the other hand, it will also cause poor water flow and affect the water use experience of residents. Especially when not in use for a long time, due to the increased pressure at a certain place caused by the water use of other users, it may cause the water flow to reverse, resulting in the problem of the water meter running backwards.

[0012] Advantages of the present utility model:

[0013] The anti-blocking water meter of the present application has a standby pipe connected in parallel between the inlet pipe and the outlet pipe. When the anti-blocking water meter is used for a long time, scale will be generated inside the water meter main body or its accessories. When too much scale accumulates, a strong local pressure will be generated inside the water meter main body. Through the arrangement of the sealing portion and the elastic telescopic portion, when more scale is generated inside the water meter main body or its accessories, the local pressure on the side of the water meter close to the inlet pipe will increase. At this time, the pressure will squeeze the sealing portion to compress the elastic telescopic portion until the sealing portion opens. At this time, the water flow can flow out through the standby pipe to the outlet pipe. Such an arrangement can improve the service life of the anti-blocking water meter. The anti-blocking water meter improves reliability by enabling the standby pipe to ensure smooth water flow when the water meter is blocked, reducing the risk of water cut-off. The anti-blocking water meter of the present application also reduces the maintenance cost, reduces the need for regular cleaning or replacement of the water meter, and enhances safety, avoiding the impact on the water meter main body caused by excessive pressure.

Specific embodiments

[0019] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the specific embodiments of the present utility model will be clearly and completely described below.

[0020] The present application discloses an anti-clogging water meter 100, as Figure 1 shown, which includes a water meter main body 11, a water inlet pipe 12, a water outlet pipe 13 and a spare pipe 14. The water meter main body 11 includes a hollow main body cavity, as Figure 2As shown, the water meter main body 11 includes a water meter disc 111 provided on one side of the water meter main body 11 and an impeller 112 provided in the main body cavity. The water inlet pipe 12 is provided on one side of the water meter main body 11 and penetrates into the main body cavity. The water outlet pipe 13 is provided on the side of the water meter main body 11 away from the water inlet pipe 12 and penetrates into the main body cavity. One end of the spare pipe 14 is connected to the side of the water inlet pipe 12 away from the water meter main body 11, and the other end of the spare pipe 14 is connected to the side of the water outlet pipe 13 away from the water meter main body 11. A sealing portion 141 capable of preventing water from entering the spare pipe 14 from the water inlet pipe 12 is provided at the connection of the spare pipe 14 to the water inlet pipe 12. An elastic telescopic portion 142 is provided on the side of the sealing portion 141 away from the water inlet pipe 12, and one end of the elastic telescopic portion 142 away from the sealing portion 141 is connected to the spare pipe 14. A spare pipe accommodating cavity with a width larger than that of the spare pipe 14 is provided in the spare pipe 14. The spare pipe 14 includes a spare impeller 143 provided in the spare pipe accommodating cavity, and the spare impeller 143 is connected to the water meter main body 11. Scale will be generated in the pipeline after the water meter has been used for a long time. When the scale accumulates too much, the local pressure in front of the scale accumulation in the pipeline will increase. On the one hand, the locally increased pressure will affect the components inside the water meter. On the other hand, the blocked scale also affects the water use experience of residents. The anti-blocking water meter 100 of the present application is provided with a spare pipe 14 in parallel between the water inlet pipe 12 and the water outlet pipe 13. When the anti-blocking water meter 100 is used for a long time, scale will be generated inside or on the accessories of the water meter main body 11. When the scale accumulates too much, a strong local pressure will be generated inside the water meter main body 11. In the present application, by providing the sealing portion 141 and the elastic telescopic portion 142, when more scale is generated inside or on the accessories of the water meter main body 11, the local pressure on the side of the water meter close to the water inlet pipe 12 will increase. At this time, the pressure will squeeze the sealing portion 141 to compress the elastic telescopic portion 142 until the sealing portion 141 is opened. At this time, the water flow can flow out through the spare pipe 14 to the water outlet pipe 13. Such a setting can extend the service life of the anti-blocking water meter 100. The anti-blocking water meter 100 improves reliability. By enabling the spare pipe 14 when the water meter is blocked, the water flow is ensured to be smooth, reducing the risk of water cut-off. The anti-blocking water meter 100 of the present application also reduces the maintenance cost, reduces the need for regular cleaning or replacement of the water meter, and enhances the safety, avoiding the impact on the water meter main body 11 caused by excessive pressure.

[0021] As an implementation, as Figure 3As shown in the figure, a check valve plate 131 having the same shape as the inlet pipe 12 and two abutting members 132 for restricting the movement of the check valve plate 131 are provided inside the outlet pipe 13. A check valve rod is provided in the middle of the check valve plate 131. The check valve plate 131 is connected to the inlet pipe 12 through the check valve rod. One of the abutting members 132 is provided at one end of the inlet pipe 12 close to the check valve plate 131, and the other abutting member 132 is provided on the inlet pipe 12. The provided check valve plate 131 can rotate in the outlet pipe 13 through the check valve rod, and the abutting member 132 is used to limit the position of the check valve plate 131. The abutting member 132 provided at one end of the inlet pipe 12 close to the check valve plate 131 is used to prevent water from flowing back from the outlet pipe 13 to the inlet pipe 12, and can prevent pollution and potential water hammer effects. The abutting member 132 provided on the inlet pipe 12 is used to limit the position of the check valve plate 131 when the outlet pipe 13 is discharging water normally, preventing the check valve plate 131 from rotating continuously, thereby protecting the check valve plate 131 from damage and ensuring the stability of its function at the same time.

[0022] As an implementation manner, a baffle plate 144 hinged to the inside of the standby pipe 14 and a limiting portion 145 for limiting the baffle plate 144 are provided inside the standby pipe 14 on the side close to the outlet pipe 13. The hinged portion of the baffle plate 144 is close to the inlet pipe 12, and the distance between the hinged portion of the baffle plate 144 and the outlet pipe 13 is less than the length of the baffle plate 144 in the direction from the inlet pipe 12 to the outlet pipe 13. The baffle plate 144 can act as a one-way valve to prevent water flow from flowing back from the outlet pipe 13 to the standby pipe 14. The distance between the hinged portion of the baffle plate 144 and the outlet pipe 13 is less than the length of the baffle plate 144 in the direction from the inlet pipe 12 to the outlet pipe 13. The limiting portion 145 is used to prevent the baffle plate 144 from flipping inwardly into the standby pipe 14. It can be such that when the standby pipe 14 is not in use, the water flow in the pipe can impact the baffle plate 144 during the flow, causing the baffle plate 144 to close.

[0023] As an implementation manner, as Figure 4 shown, a rough scraping plate 113 is provided inside the water meter main body 11. The scraping plate 113 is provided on one side of the impeller 112 and is made of stainless steel. The impeller 112 is an important component for metering in the water meter. The accumulation of water scale will affect the rotation of the impeller 112, and thus affect the metering accuracy of the water meter. The rough scraping plate 113 can contact and scrape off the water scale attached to the impeller 112 or the pipe wall with the drive of the water flow inside the water meter, preventing blockage caused by the accumulation of water scale. By continuously scraping off the water scale, the speed of water scale accumulation is reduced, thereby reducing the frequency of cleaning or maintenance required for the water meter, saving maintenance time and cost. Using stainless steel material to make the scraping plate 113 can improve its corrosion resistance, because in the water environment, metal components are prone to corrosion, and stainless steel has strong corrosion resistance, which can extend the service life of the scraping plate 113.

[0024] As an implementation manner, detachable magnetic adsorption rings 15 are respectively arranged on the outer sides of the water inlet pipe 12 and the standby pipe 14, and the magnetic adsorption ring 15 on the standby pipe 14 is arranged on the side close to the water inlet pipe 12. The magnetic adsorption ring 15 can adsorb iron impurities in the water, including rust particles, reducing the chance of entering the inside of the water meter main body 11, protecting precision components such as the impeller 112 from wear or blockage by rust particles. By reducing the erosion of internal parts such as the impeller 112 by impurities such as rust, the service life of the water meter can be extended, and the frequency of replacing the water meter due to damage of internal parts can be reduced. The magnetic adsorption ring 15 is designed in a detachable form, and maintenance personnel can conveniently remove the magnetic adsorption ring 15 for cleaning or replacement, and can regularly remove the adsorbed iron impurities from the disassembled water meter to keep the system clean.

[0025] As an implementation manner, a water inlet valve is arranged on the side of the water inlet pipe 12 away from the water meter main body 11. When it is necessary to disassemble the water meter for maintenance or replacement, the water flow can be cut off by closing the water inlet valve, which prevents water from flowing out during the disassembly process.

[0026] As an implementation manner, a transparent observation window 114 is arranged on one side of the water meter main body 11. The observation window 114 allows users or maintenance personnel to directly see the situation inside the water meter, including the rotation condition of the impeller 112 and whether there is accumulation of impurities or scale, facilitating timely discovery of problems.

[0027] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present utility model.
