[0023] The utility model will be explained further in detail now in combination with the drawings. These drawings are all simplified schematic diagrams, and only the basic structure of the utility model is schematically shown, so it only shows the structure related to the utility model.

[0024] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another component, it can be directly disposed on the other component or indirectly disposed on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.

[0025] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or component referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0026] Please refer to Figures 1-6 The utility model provides a kind of ceramic inlay type anticorrosive flowmeter float and metal pipe float flowmeter, including float guide rod 11, float main body 12 of fixed installation on float guide rod 11 and ceramic measuring edge 13 of fastening installation on float main body 12, ceramic measuring edge 13 includes sleeve joint part 131 of close fitting installation on float main body 12 and the measuring part 132 of being set to the outside of sleeve joint part 131, sleeve joint part 131 and measuring part 132 are integrally formed using ceramic material.

[0027] The ceramic measuring edge 13 is arranged outside the float body 12, so that when the fluid to be measured is a high-temperature fluid or the measurement environment is a high-temperature environment, the ceramic measuring edge 13 is not affected by temperature due to the high-temperature resistance of the ceramic, and the ceramic measuring edge 13 is not prone to deformation, thereby further expanding the application range of the float and enhancing the practicability of the float. When the float body 12 is driven to start moving by the fluid, the ceramic measuring edge 13 can still maintain a hard shape, and when the ceramic measuring edge 13 is clamped with the inner wall of the float flowmeter, the ceramic measuring edge 13 is still in a hard shape due to the temperature resistance, thereby better providing a reaction force for the float body 12 to float upward, so that the flow rate of the fluid can be more accurately measured.

[0028] In the embodiment, the float guide rod 11 and the float body 12 are fixedly installed. When the float guide rod 11 is installed in the float flowmeter, the fluid flow drives the float guide rod 11 to move up and down in the fluid inner cavity of the float flowmeter. When the fluid drives the float body 12 to move downward, the clamping portion is clamped with the inner wall of the float flowmeter, and then a reaction force is transmitted to the float to make it float upward. At this time, the flow rate of the fluid passing through the flowmeter can be calculated by reading the floating value of the float body 12.

[0029] Further, the float body 12 includes an inner core sleeved on the float guide rod 11 and a float shell installed on the outer side of the inner core. The inner core is made of magnetic stainless steel material. The use of the material can remotely read the floating position of the float, so that the float can be applied to various float flowmeters, thereby enhancing the practicability of the float and the convenience of data measurement.

[0030] Further, the float shell is made of fluoroplastic material. The material has the characteristics of high-temperature resistance and corrosion resistance, and the surface of the fluoroplastic material has small friction and surface tension, and can not adhere to any substances. Therefore, the shell made of fluoroplastic material can make the fluid flow more smoothly in the fluid passage 3. When the float is driven downward by the fluid, the fluid can not adhere to the surface of the float, and the upward floating resistance caused by the material can be eliminated when the float floats upward, thereby ensuring the accuracy of fluid speed measurement. When the fluid is a fluid with strong corrosion resistance or high temperature, the shell can better adapt to the flow of the fluid.

[0031] As shown in FIG. 1, Figure 4 The inner side of the sleeve portion 131 is provided with a plurality of protrusions 133 for pressing and fitting on the outer wall surface of the float body 12.

[0032] In the embodiment, the connection of the ceramic measuring edge 13 and the float body 12 is that the sleeve joint part 131 is pressed against the outside of the float body 12, the contact area of the connection part and the outer wall of the float body 12 is increased by the setting of the protrusion 133, and then the friction is increased, so that the sleeve joint part 131 can be tightly pressed against the outside of the float body 12, and the tightness and stability of the connection of the ceramic measuring edge 13 and the float body 12 are ensured.

[0033] As shown in Figure 2 and Figure 3 , the float body 12 is a stepped shaft, and the sleeve joint part 131 is positioned by abutting against the shaft shoulder of the stepped shaft.

[0034] In the embodiment, the position of the ceramic measuring edge 13 ensures that the sleeve joint part 131 and the outer wall of the large-diameter section 121 are in the same plane, and the clamping part is a component protruding from the outer wall of the float body 12, so that the smoothness during the flow of fluid is ensured.

[0035] Further, as shown in Figure 3 , the measuring part 132 is provided with a measuring section 134 for adapting to the inner wall of the flowmeter, and when the float is driven downward by the fluid, the measuring section 134 will be attached to the inner wall of the float flowmeter, so that the flow rate of the fluid can be more accurately calculated.

[0036] As shown in Figure 1 and Figure 2 , the float body 12 is made of fluoroplastic material, and the float body 12 includes a large-diameter section 121, a medium-diameter section 122 and a small-diameter section 123 in sequence from large to small; the upper end of the ceramic measuring edge 13 abuts against the lower side of the large-diameter section 121, and the lower end is fixedly installed on the outer side of the medium-diameter section 122 by hot melting fluoroplastic material.

[0037] In the embodiment, the fluoroplastic end corner part of the outer side wall at the bottom of the medium-diameter section 122 is high-temperature hot-melted, so that the fluoroplastic material is dissolved under the action of high temperature, the bottom of the ceramic measuring edge 13 can be fixedly and hot-meltedly installed on the float body 12 through the dissolution of the fluoroplastic material, and the hot-melted end after hot-melted installation is arc-shaped and no longer has sharp edges and corners, so that the smooth flow of fluid can be further ensured.

[0038] The utility model also provides a metal pipe float flowmeter, as shown in Figures 1-6 , comprising a metal shell 2, a fluid passage 3 arranged in the metal shell 2, a fluid inlet 4 arranged at the top of the fluid passage 3, a fluid outlet 5 arranged at the bottom of the fluid passage 3 and a ceramic inlaid type corrosion-resistant flowmeter float as above arranged in the fluid passage 3 through a stop piece 6.

[0039] In the embodiment, fluid flows into the fluid passage 3 from the fluid inlet 4, pushes the float guide rod 11 in the fluid passage 3 to move downward, after the measuring part 132 of the float body 12 is clamped on the inner wall of the metal shell 2, the float is floated upward by the reaction force and the floating force of the float, the flow velocity of the fluid is measured by the floating scale of the float, and finally the fluid flows out from the fluid outlet 5.

[0040] It is further explained that the inner wall clamped with the measuring part 132 in the fluid passage 3 is inclined at an angle of 30 degrees, and the measuring section 134 of the measuring part 132 is also inclined at an angle of 30 degrees, so that when the float moves downward, the measuring section 134 can be closely attached to the inner wall of the fluid passage 3, so that the inner wall can provide sufficient reaction force to the float, further enabling the float to quickly float upward according to its own floating force, thereby shortening the measurement time and ensuring the accuracy of the fluid flow rate measurement.

[0041] It should be understood that the specific embodiments described above are only used to explain the present application, and are not used to limit the present application. The obvious changes or modifications derived from the spirit of the present application are still within the protection scope of the present application.
