Description

Technical Field

[0001] The utility model relates to the field of liquid metering devices, in particular to a liquid meter. Background Art

[0002] Water towers are generally used to store water in residential areas, and some are also an important part of the production process of water plants. Water towers are tall structures used to store and distribute water to maintain and regulate the amount of water and water pressure in the water supply network. The working principle is: when the water in the water tank at the top of the water tower drops to the minimum water level of normal water supply, the water tower automatically starts the water supply equipment to supply water to the water tank, and stops supplying water when the water level in the water tank is sufficient. In the process of supplying water to the water tank, the staff cannot measure the water level in the water tank in real time, and thus cannot record the minimum water level and sufficient water level of the water tank, and thus cannot determine the start and stop time of the water supply equipment. In order to ensure that the water tower can work normally after installation, a liquid meter is now needed to measure the water level in the water tank. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, a liquid meter includes a graduated tube assembly 100, a base 200 and a buoyancy assembly 300. The liquid meter is installed on the upper end surface of a water tank at the top of a water tower through the base 200.

[0023] The graduated tube assembly 100 comprises a graduated tube 101 and a connecting piece 102 installed at either end thereof, a thread groove 103 is provided at one end of the connecting piece 102 away from the graduated tube 101, a threaded protrusion 104 is provided at the middle of the base 200, and the calibers of the threaded groove 103 and the threaded protrusion 104 are adapted to each other, and are used to fasten the connection structure between the base 200 and the graduated tube 101;

[0024] The buoyancy assembly 300 includes a float 301 and a stainless steel tube 302. A scale slider 303 is provided at one end of the stainless steel tube 302 away from the float 301. The scale slider 303 is specifically a polyurethane slider whose shape is adapted to the scale tube 101. The polyurethane slider has good wear resistance and elasticity, as well as a low outer surface friction coefficient, which can reduce the influence of friction on the measurement results.

[0025] A through hole 201 is provided in the middle of the connecting piece 102, the threaded groove 103 and the threaded protrusion 104. The end of the scale tube 101 close to the float 301 is fixedly connected to the limit block 105, and the stainless steel tube 302 is slidably connected to the scale tube 101 through the scale slider 303; the scale slider 303, the stainless steel tube 302, the limit block 105 and the float 301 are used to measure the water level in the water tank; specifically, when the float 301 sinks into the water, the water in the water tank provides buoyancy for the float 301, so that the float 301 floats to the water surface. In this process, the float 301 drives the stainless steel tube 302 to move upward, and then drives the scale slider 303 to move upward to the corresponding scale; the limit block 105 is used to limit the scale slider 303 to prevent the stainless steel tube 302 from falling out of the scale tube 101 during the sinking process of the float 301.

[0026] In this embodiment, the calibrated tube assembly 100 also includes a calibrated tube fastener 107. One end of the calibrated tube fastener 107 is fixedly connected to the end of the calibrated tube 101 close to the buoyancy assembly 300. The other end of the calibrated tube fastener 107 is provided with a threaded protrusion 104 that is the same as the middle part of the base 200. The other end of the connecting piece 102 is also provided with a threaded groove 103. The calibrated tube fastener 107 is installed in the other end of the connecting piece 102 through the threaded protrusion 104. The threaded protrusion 104 on the calibrated tube fastener 107 cooperates with the threaded groove 103 on the connecting piece 102, so that the connection structure between the calibrated tube 101 and the connecting piece 102 can be made more stable.

[0027] In this embodiment, a small fastener 106 is fixedly connected to the end of the graduated tube 101 away from the buoyancy assembly 300 .

[0028] In this embodiment, the base 200 further includes threaded through holes 202 arranged around the threaded protrusion 104, which are used to cooperate with the screw through holes 202 to fix the base 200 on the upper end surface of the water tank.

[0029] In this embodiment, the outer shape of the floating block 301 is spherical; setting the floating block 301 to be spherical can enable the floating block 301 to bear the buoyancy from the water surface more evenly.

[0030] It should be noted that the utility model is to install the utility model on the upper end surface of the container to be measured in advance by screwing screws through the screw through holes 202 through the multiple threaded holes on the base 200 before the liquid is introduced into the container. In this embodiment, the water tank on the top of the water tower is selected;

[0031] In the water tank, when water is flowing in or out of the water tank, the water level in the water tank will change. Since the float 301 is subjected to the buoyancy from the water, the float 301 moves upward or downward following the water surface, and at the same time drives the stainless steel pipe 302 to move upward or downward, and the scale slider 303 located on the stainless steel pipe 302 slides upward or downward synchronously. During this process, the staff can obtain the real-time water level in the water tank by observing the scale on the scale tube 101 and the corresponding position of the scale slider 303.

[0032] The beneficial effects of a liquid meter 22 of the utility model are as follows:

[0033] The utility model installs the graduated tube 101 and the buoyancy assembly 300 on the water tank at the top of the water tower through the base 200. The float block 301 drives the stainless steel tube 302 to slide downward under the action of gravity, and finally stays on the water surface inside the water tank due to the buoyancy from the water. At this time, the water level inside the water tank can be read according to the position of the graduated tube 101 corresponding to the graduated slider 303 on the top of the stainless steel tube 302. In addition, the utility model can also be installed on a container of volatile liquid or light-sensitive liquid, and is used to measure the liquid level in the corresponding container without opening the container.

[0034] The utility model and its implementation methods are described above. This description is not restrictive. What is shown in the accompanying drawings is only one of the implementation methods of the utility model. The actual content is not limited to this. In short, if ordinary technicians in this field are inspired by it, without departing from the inventive purpose of the utility model, they can creatively design structural methods and embodiments similar to the technical scheme, which should all fall within the protection scope of the utility model.
