Description

Technical Field

[0001] The utility model relates to the technical field of water meters, in particular to a water meter that can prevent blockage and is convenient for cleaning scale. Background Technique

[0002] With the acceleration of the urbanization process, water resource management and metering have become particularly important. As a key device for measuring water resource consumption, water meters play a crucial role in daily life and industrial applications. However, traditional water meters often encounter problems such as blockage and scale accumulation during use. These problems not only affect the accurate metering of water meters but also shorten the service life of water meters.

[0003] Minerals in water are prone to accumulate inside the water meter to form scale during long-term use, resulting in blockage of the internal flow channels of the water meter and affecting the normal operation of the water meter. The accumulation of scale will also cause wear inside the water meter and shorten the service life of the water meter. When scale or blockage occurs inside the water meter, traditional water meters are difficult to disassemble and inconvenient to clean because there is no specially designed filter or cleaning device, making the cleaning work complex and time-consuming. Moreover, during the long-term use of traditional water meters, due to the accumulation of scale, the sealing performance is prone to decline, resulting in water leakage. Poor sealing not only causes waste of water resources but also further affects the working performance of the water meter. With the progress of technology, more and more new materials and technologies have been applied to the design and manufacture of water meters to solve the above problems. For example, measures such as using corrosion-resistant materials, designing reasonable flow channels, and adding cleaning devices can effectively prevent scale accumulation and blockage, but the above methods are relatively complex or costly. Therefore, it is particularly necessary to develop a relatively simple water meter that can prevent blockage and is convenient for cleaning scale. Content of the Utility Model

[0004] In order to solve the deficiencies of the prior art, this application discloses a water meter that can prevent blockage and is convenient for cleaning scale, which has a relatively simple structure, can prevent blockage, and can clean scale in a timely manner.

[0005] The utility model discloses a water meter that can prevent blockage and is convenient for cleaning scale, which comprises a main body, a water inlet pipe, a water outlet pipe and a pipe cover. The inside of the main body includes a hollow accommodating cavity, and an impeller is arranged in the accommodating cavity. The water inlet pipe is arranged on one side of the main body and penetrates into the accommodating cavity. On one side of the water inlet pipe, there is a water inlet anti-scale pipe communicating with the water inlet pipe. An inlet drainage plug plate is arranged in the water inlet anti-scale pipe, and inwardly concave water inlet anti-scale threads are arranged on the inner wall of the water inlet anti-scale pipe. The water outlet pipe is arranged on the other side of the main body and penetrates into the accommodating cavity. On one side of the water outlet pipe, there is a water outlet anti-scale pipe communicating with the water outlet pipe. An outlet drainage plug plate is arranged in the water outlet anti-scale pipe, and inwardly concave water outlet anti-scale threads are arranged on the inner wall of the water outlet anti-scale pipe. The pipe cover includes two, and the two pipe covers correspond to the water inlet anti-scale pipe and the water outlet anti-scale pipe respectively. A filter screen is fixedly connected to the side of the pipe cover close to the water inlet pipe. Reinforcing rods are arranged on both sides of the filter screen. One end of the filter screen away from the pipe cover includes a sealing disc provided with a plurality of through holes. On the outside of the sealing disc, there are cleaning teeth protruding outwards corresponding to the inner wall threads of the pipeline.

[0006] Further, taking the extension direction of the pipeline as the pipeline extension direction, the projection of the thread on the pipe cover in the pipeline extension direction is the thread projection, and the projection of the cleaning teeth on the pipe cover in the pipeline extension direction is the cleaning teeth projection. From the outside of the pipe cover to the center direction of the pipe cover, the length of the cleaning teeth projection is less than the length of the thread projection.

[0007] Further, the length of the inlet drainage plug plate is greater than or equal to the diameter of the water inlet pipe, and the length of the outlet drainage plug plate is greater than or equal to the diameter of the water outlet pipe.

[0008] Further, the ends of the inlet drainage plug plate and the outlet drainage plug plate close to the pipe cover gradually become wider from the center outwards and form an arc.

[0009] Further, a water inlet valve is arranged on the side of the water inlet anti-scale pipe on the water inlet pipe away from the main body.

[0010] Further, a handle is arranged on the end of the pipe cover away from the pipeline.

[0011] Further, a sealing gasket is arranged on the side of the pipe cover arranged outside the pipeline.

[0012] The beneficial effects of the utility model:

[0013] The structure of this application is relatively simple. The pipe cover of this application can be disassembled at any time, and the filter screen can be cleaned and replaced at any time. Moreover, several pipe covers can be configured for this application, and the filter screen apertures on each pipe cover are set differently, which can adapt to filtration under different water quality conditions, and an appropriate filter screen can be selected according to the water quality. The pipe cover of this application is fixed through the anti-scaling thread for water inlet and the anti-scaling thread for water outlet. However, when the pipe cover is used for a long time, scale will be generated on the anti-scaling thread for water inlet and the anti-scaling thread for water outlet. This application cleans the scale in the anti-scaling thread for water inlet and the anti-scaling thread for water outlet through the cleaning teeth protruding outward corresponding to the inner wall thread of the pipeline on the outer side of the sealing disc, preventing the scale from affecting the removal and replacement of the pipe cover.

SPECIFIC EMBODIMENTS

[0018] In order to enable those skilled in the art to better understand the solution of this utility model, the technical solutions in the specific embodiments of this utility model will be clearly and completely described below.

[0019] This application discloses a water meter 100 that prevents blockage and is convenient for cleaning scale, as Figure 1 shown, which includes a main body 11, a water inlet pipe 12, a water outlet pipe 13 and a pipe cover 13. The inside of the main body 11 includes a hollow accommodation cavity, as Figure 2As shown in the figure, an impeller 111 is arranged in the accommodation cavity. The impeller 111 is used to count the water flow rate flowing through the impeller 111. The water inlet pipe 12 is arranged on one side of the main body 11 and penetrates into the accommodation cavity. An anti-scaling water inlet pipe 121 communicating with the water inlet pipe 12 is arranged on one side of the water inlet pipe 12. An inlet water diversion plug plate 122 is arranged in the anti-scaling water inlet pipe 121. An inwardly concave anti-scaling water inlet thread 1211 is arranged on the inner wall of the anti-scaling water inlet pipe 121. The anti-scaling water inlet thread 1211 is used to fix the pipe cap 13. The water outlet pipe 13 is arranged on the other side of the main body 11 and penetrates into the accommodation cavity. An anti-scaling water outlet pipe 131 communicating with the water outlet pipe 13 is arranged on one side of the water outlet pipe 13. An outlet water diversion plug plate 132 is arranged in the anti-scaling water outlet pipe 131. An inwardly concave anti-scaling water outlet thread 1311 is arranged on the inner wall of the anti-scaling water outlet pipe 131. The anti-scaling water outlet thread 1311 is used to fix the pipe cap 13. There are two pipe caps 13, and the two pipe caps 13 correspond to the anti-scaling water inlet pipe 121 and the anti-scaling water outlet pipe 131 respectively. A filter screen 131 is fixedly connected to the side of the pipe cap 13 close to the water inlet pipe 12, as Figure 3As shown in the figure, reinforcing bars 132 are provided on both sides of the filter screen 131. The reinforcing bars 132 provided on both sides of the filter screen 131 can enhance the structural strength of the filter screen 131, preventing the filter screen 131 from deforming or shifting under the impact of water flow and the rotation of the pipe cover 13. One end of the filter screen 131 away from the pipe cover 13 includes a sealing disc 133 provided with a number of through holes. On the outside of the sealing disc 133, cleaning teeth 1331 protruding outward corresponding to the inner wall thread of the pipe are provided. The water inlet diversion plug 122 and the water outlet diversion plug 132 are used for diversion, diverting the water flowing through the water inlet pipe 12 and the water outlet pipe 13 into the water inlet anti-scaling pipe 121 and the water outlet anti-scaling pipe 131, so that the filter screen 131 provided on the pipe cover 13 filters the water flow. The pipe cover 13 of the present application can be disassembled at any time, and the filter screen 131 can be cleaned and replaced at any time. And the pipe cover 13 of the present application can be configured with several, and the aperture of the filter screen 131 on each pipe cover 13 is set differently, which can adapt to the filtration under different water quality conditions, and the appropriate filter screen 131 can be selected according to the water quality. The pipe cover 13 of the present application is fixed by the water inlet anti-scaling thread 1211 and the water outlet anti-scaling thread 1311. However, when the pipe cover 13 is used for a long time, scale will be generated on the water inlet anti-scaling thread 1211 and the water outlet anti-scaling thread 1311. In the present application, the cleaning teeth 1331 protruding outward corresponding to the inner wall thread of the pipe are provided on the outside of the sealing disc 133 to clean the scale in the water inlet anti-scaling thread 1211 and the water outlet anti-scaling thread 1311, preventing the scale from affecting the removal and replacement of the pipe cover 13. The present application also configures a pipe cover 13 and cleaning teeth 1311 without a filter screen 131 and a cleaning disc 133, which can clean the deep threads of the water inlet anti-scaling thread 1211 and the water outlet anti-scaling thread 1311. The water inlet anti-scaling pipe 121 and the water outlet anti-scaling pipe 131 of the present application are used for the accumulation and cleaning of scale therein, preventing scale from generating dirt in other places of the water inlet pipe 12 and the water outlet pipe 13, and improving the service life of the water outlet pipe 13 and the water inlet pipe 12.

[0020] As an implementation manner, taking the extension direction of the pipe as the pipe extension direction, the projection of the thread on the pipe cover 13 in the pipe extension direction is the thread projection, and the projection of the cleaning teeth 1331 on the pipe cover 13 in the pipe extension direction is the cleaning teeth 1331 projection. From the outside of the pipe cover 13 to the center direction of the pipe cover 13, the length of the cleaning teeth 1331 projection is less than the length of the thread projection. From the outside of the pipe cover 13 to the center direction of the pipe cover 13, the length of the cleaning teeth 1331 projection is less than the length of the thread projection, and the cleaning teeth 1331 are completely arranged inside the thread. Such a setting can avoid generating a gap between the thread and the cleaning teeth 1331, preventing water from leaking between the thread and the cleaning teeth 1331, and improving the tightness of the pipe cover 13. And the length of the cleaning teeth 1331 is relatively short, which can ensure that the cleaning teeth 1331 will not protrude excessively during rotation, so that the contact between the pipe cover 13 and the inner wall of the pipe is closer, enhancing the overall sealing reliability.

[0021] As an implementation manner, the length of the water inlet diversion plug 122 is greater than or equal to the diameter of the water inlet pipe 12, and the length of the water outlet diversion plug 132 is greater than or equal to the diameter of the water outlet pipe 13. Such a setting can enable the water in the water inlet pipe 12 and the water in the water outlet pipe 13 to completely enter the water inlet anti-scaling pipe 121 and the water outlet anti-scaling pipe 131, can completely use the filter screen 131 to filter water, and can prevent the water flow in the water inlet pipe 12 and the water flow in the water outlet pipe 13 from directly impacting the filter screen 131. The water flow impact first impacts on the water inlet diversion plug 122 and the water outlet diversion plug 132, which prolongs the service life of the filter screen 131.

[0022] As an implementation manner, the ends of the water inlet diversion plug 122 and the water outlet diversion plug 132 close to the pipe cover 13 gradually become wider from the center outwards and form an arc. Such a design can enable the water impacting on the water inlet diversion plug 122 from the water inlet pipe 12 to impact on the water inlet anti-scaling thread 1211, and clean the scale on the water inlet anti-scaling thread 1211, having a certain self-cleaning ability. Similarly, the water outlet diversion plug 132 also has a certain self-cleaning ability.

[0023] As an implementation manner, a water inlet valve is provided on the side of the water inlet anti-scaling pipe 121 on the water inlet pipe 12 away from the main body 11. The water inlet valve can block the water flow in the water inlet pipe 12 when it is necessary to replace the pipe cover 13 or clean the filter screen 131, which is convenient for replacing the pipe cover 13 and removing the pipe cover 13 to clean the filter screen 131.

[0024] As an implementation manner, a handle 134 is provided on the end of the pipe cover 13 away from the pipeline. The handle 134 is used to facilitate the removal of the pipe cover 13.

[0025] As an implementation manner, a sealing gasket is provided on the side of the pipe cover 13 arranged outside the pipeline. The sealing gasket is used to seal the pipe cover 13 to prevent the pipe cover 13 from leaking water.

[0026] 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.
