Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, and in particular to a ball valve with water flow monitoring function. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (ball) is driven by the valve stem and rotates around the valve's axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, with their V-shaped ball core and hard alloy-faced metal seat, possess strong shearing force, making them particularly suitable for media containing fibers, small solid particles, etc. Multi-port ball valves not only flexibly control the merging, splitting, and switching of flow directions in pipelines, but also allow the closure of any channel while connecting two other channels.

[0003] Currently, most ball valves only have the function of cutting off fluid and do not have the function of flow monitoring. When there is water leakage at the ball valve connection or in the pipeline, it cannot be detected in time, resulting in a delay in fault detection. Utility Model Content

[0004] Therefore, it is necessary to provide a ball valve with water flow monitoring function to address the problem of delayed fault detection when water leakage occurs.

[0005] A ball valve with water flow monitoring function includes: a ball valve body, flanges fixedly connected to both ends of the ball valve body, and a flow monitoring mechanism disposed inside the ball valve body; the flow monitoring mechanism is disposed at the water outlet inside the ball valve body and is used to monitor the amount of water flowing through the ball valve body.

[0006] In one embodiment, the flow monitoring mechanism includes a mounting ring threaded to the inner wall of the ball valve body, a bracket fixedly connected to the inner wall of the mounting ring, a rotating seat rotatably connected to the side of the bracket near the ball valve body, a plurality of impellers evenly distributed on the surface of the rotating seat, and a magnet fixedly connected to the side of the impellers away from the ball valve body. A Hall sensor corresponding to the magnet is provided on the surface of the ball valve body, and a connecting wire is provided on the Hall sensor.

[0007] In one embodiment, a limiting ring is fixedly connected inside the ball valve body, and the length of the mounting ring is the same as the distance from the limiting ring to the flange at the nearest end.

[0008] In one embodiment, the inner wall of the ball valve body is provided with an internal thread, and the outer surface of the mounting ring is provided with an external thread corresponding to the internal thread.

[0009] In one embodiment, a filter plate is fixedly connected to one end of the mounting ring near the ball valve body, and the filter plate has multiple through holes evenly distributed on its surface.

[0010] In one embodiment, the mounting ring is made of brass, and the impeller and rotating seat are made of polytetrafluoroethylene.

[0011] In one embodiment, the magnet is a neodymium iron boron magnet, and the surface of the magnet is coated with epoxy resin potting compound.

[0012] In one embodiment, a sealing ring is provided on the side of the limiting ring near the mounting ring.

[0013] Beneficial effects

[0014] The ball valve described above is equipped with a flow monitoring mechanism. After the ball valve body is closed, if water leakage occurs, the water flowing through the ball valve body will drive the impeller and rotating seat to rotate, thereby causing the magnet on the impeller to rotate. The rotation speed of the magnet is detected by a Hall sensor, thereby monitoring the water flow rate, which makes it easier to understand the pipeline leakage situation in a timely manner and reduce losses.

[0015] Tighten the bracket to remove the mounting ring from the ball valve body, which facilitates maintenance and replacement of the components inside the mounting ring, and makes installation and disassembly easy. Attached Figure Description

[0028] The following is combined Figures 1-4This invention describes a ball valve with water flow monitoring function.

[0029] In one embodiment, a ball valve with water flow monitoring function includes: a ball valve body 101, flanges 102 fixedly connected to both ends of the ball valve body 101, and a flow monitoring mechanism 200 disposed inside the ball valve body 101. The flow monitoring mechanism 200 is disposed at the water outlet inside the ball valve body 101 and is used to monitor the amount of water flowing through the ball valve body 101. The flow monitoring mechanism 200 includes a mounting ring 203 threadedly connected to the inner wall of the ball valve body 101, a bracket 204 fixedly connected to the inner wall of the mounting ring 203, a rotating seat 205 rotatably connected to the side of the bracket 204 near the ball valve body 101, a plurality of impellers 206 evenly distributed on the surface of the rotating seat 205, and a magnet 207 fixedly connected to the side of the impellers 206 away from the ball valve body 101. A Hall sensor 201 corresponding to the magnet 207 is disposed on the surface of the ball valve body 101, and a connecting wire 202 is disposed on the Hall sensor 201.

[0030] Align the mounting ring 203 with the inner wall of the ball valve body 101. The rotating bracket 204 drives the mounting ring 203 to rotate, and the external thread 208 and the limiting ring 211 screw the mounting ring 203 into the ball valve body 101. This installation prevents the mounting ring 203 from being washed away by the water flow and ensures its stability inside the ball valve body 101. When water flows inside the ball valve body 101, the water flow drives the impeller 206 and the rotating seat 205 to rotate, thereby moving the position of the magnet 207 and changing the magnetic field. The Hall sensor 201 detects the magnetic field, thus detecting the rotational speed of the magnet 207 and monitoring the water flow rate. The Hall sensor 201 is powered and signals are transmitted through the connecting line 202. The Hall sensor 201 is a transducer that converts a changing magnetic field into a change in output voltage. Hall sensors are primarily used to measure magnetic fields, but they can also measure physical quantities that generate and influence magnetic fields, such as those used in proximity switches, Hall effect sensors, position measurement devices, speed measurement devices, and current measurement devices.

[0031] like Figure 2 and Figure 4 As shown, a limiting ring 211 is fixedly connected inside the ball valve body 101. The length of the mounting ring 203 is the same as the distance from the limiting ring 211 to the flange 102 at the nearest end. An internal thread 210 is formed on the inner wall of the ball valve body 101, and an external thread 208 corresponding to the internal thread 210 is formed on the outer surface of the mounting ring 203. A filter plate 209 is fixedly connected to one end of the mounting ring 203 near the ball valve body 101. Multiple through holes are evenly distributed on the surface of the filter plate 209.

[0032] Impurities in the water are filtered by the filter plate 209 to prevent them from affecting the rotation of the impeller 206 and the rotating seat 205. The installation position of the mounting ring 203 is limited by the setting of the limit ring 211 to ensure the stability of the mounting ring 203 when the ball valve body 101 is connected to the pipeline.

[0033] The mounting ring 203 is made of brass, which is corrosion-resistant and reduces maintenance frequency. The impeller 206 and the rotating seat 205 are made of polytetrafluoroethylene (PTFE), which reduces weight and allows them to rotate even with a small water flow. The magnet 207 is a neodymium iron boron magnet, and its surface is encapsulated with epoxy resin. The encapsulation protects the magnet 207 from corrosion and weakening of its magnetism, thus preventing interference with water flow monitoring. A sealing ring is provided on the side of the limit ring 211 near the mounting ring 203.

[0034] Working principle: The ball valve body 101 is connected to the pipeline via flange 102. The flow rate in the pipeline is controlled by opening and closing the ball valve body 101. When liquid flows through the ball valve body 101, the impeller 206 drives the rotating seat 205 to rotate, thereby causing the magnet 207 to rotate inside the ball valve body 101. The rotation of the magnet 207 causes a change in the magnetic field. The position of the magnet 207 is detected by the Hall sensor 201, thus monitoring the water flow rate. When the ball valve body 101 is closed, leakage is detected by monitoring the water flow rate, making it easy to know whether there is a leak in the pipeline. When the ball valve body 101 is open, the water flow rate is monitored to control the amount of water used, making it convenient to use.

[0035] It should be noted that the ball valve body 101, Hall sensor 201, rotating seat 205, impeller 206, magnet 207, etc. mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
