Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a V-cone flow meter with an anti-blocking structure. Background Art

[0002] The principle of the existing V-type inner cone flowmeter is to use a conical throttling piece coaxially installed in the pipeline to gradually throttle the fluid to the inner wall of the pipeline, and measure the flow rate by measuring the differential pressure before and after the cone. It is used for flow measurement of various gases, liquids, steam and other media in metallurgy, chemical industry, fertilizer, petroleum, natural gas, electricity and other industrial enterprises.

[0003] The working principle of the existing V-type internal cone flowmeter is based on the laws of conservation of fluid mass (continuity equation) and conservation of energy (Bernoulli equation). When the fluid flows through the cone, due to the throttling effect of the cone, a pressure difference ΔP will be generated before and after the cone. The square root of the pressure difference ΔP is directly proportional to the flow rate q. The flow rate is calculated by measuring the pressure difference, but the existing device still has some defects.

[0004] For example, the V-cone flowmeter with publication number CN2831055Y includes a tube body and a flange arranged at its end, and is also provided with a positive pressure port and a negative pressure port that penetrate the inner wall of the pipeline, and the positive pressure port and the negative pressure port are respectively provided with pressure joints. A support is built into one end of the pipeline, and a cone assembly is provided at the end of the support. The support is a hollow structure, and a bracket that matches the cone assembly is provided at its inner end. A step is provided at one end of the tube body, and a convex ring that matches the step of the tube body is provided at the outer end of the support. The central axis of the support coincides with the central axis of the tube body; the central axis of the cone assembly coincides with the central axis of the tube body.

[0005] The above device has some problems, such as being troublesome to use, inconvenient to install, poor measurement effect when the support is set, poor anti-blocking effect when in use, poor stability during measurement, and inconvenient to use. Therefore, a V-cone flowmeter with an anti-blocking structure is proposed to solve the above problems. Utility Model Content

[0027] First, after moving the machine body 1 to the designated position, connect the two sides of the machine body 1 with the external water pipe 3. First, insert the right side of the machine body 1 into the water inlet pipe 3. At this time, take out the fixing block 6, and twist the handle on the fixing block 6 at the same time to rotate the internal screw rod 7. When the screw rod 7 rotates, the sliders 8 at the upper left and right ends move toward the middle at the same time, and at the same time drive the fixing sleeve 9 symmetrically arranged below to move toward the middle to fix the connection between the machine body 1 and the water pipe 3. At this time, put a rubber gasket 5 at the connection between the machine body 1 and the left side, and then twist the hexagonal bolt 4 to complete the installation of the machine body 1 and the water pipes 3 on the left and right sides. Placing the gasket 5 at the connection can make the connection tighter. At the same time, the motor 16 can be started to drive the gear 18 to rotate during use. Since the gear 18 and the rack 19 are meshed, the rack 19 moves on the slide bar 20 and drives the front baffle 17 to move to block the water flow inside the machine body 1.

[0028] A push rod 10 is arranged inside the machine body 1, and the front end of the push rod 10 is connected to a moving block 11. The push rod 10 is symmetrically arranged about the center inside the machine body 1, and the front end of the push rod 10 is provided with a moving block 11, and the front end of the moving block 11 is provided with a sharp protrusion, and a gasket 5 is arranged at the contact position between the moving block 11 and the machine body 1.

[0030] Working principle: When using the V-cone flowmeter with an anti-blocking structure, first move the body 1 to the specified position, then connect the two sides of the body 1 and the external water pipe 3, first insert the right side of the body 1 into the water inlet pipe 3, then take out the fixing block 6, and at the same time turn the handle on the fixing block 6 to rotate the internal screw rod 7, and while the screw rod 7 rotates, the sliders 8 at the upper left and right ends move toward the middle at the same time, and at the same time drive the fixing sleeve 9 symmetrically arranged below to move toward the middle to fix the connection between the body 1 and the water pipe 3. At this time, put a rubber gasket 5 at the connection between the body 1 and the left side, and then turn the hexagonal bolt 4 to complete the installation of the body 1 and the water pipes 3 on the left and right sides. Placing the gasket 5 at the connection can make the connection tighter. At this time, open the water valve to allow water to flow into the body 1 through the water pipe 3. First, the pressure of the water flow directly flowing through is extracted through the first pressure-conducting pipe 12, and then the water flows The transition zone on the surface of the V-shaped cone 14 has a good flow stabilization effect. At this time, after the pressure is extracted for the second time through the second pressure-inducing pipe 15 behind the V-shaped cone 14, the V-shaped cone 14 is supported by the support rod 13 below, which can effectively prevent the V-shaped cone 14 from shaking due to excessive pressure during use. After being transmitted to the detector 2 above for detection, the current flow rate can be calculated. At the same time, when blockage occurs inside the body 1 during use, the first push rod 10 can be used to drive the moving block 11 to move toward the middle, and the sharp protrusions in front of the moving blocks 11 at the upper and lower ends will clear the blocked materials, so that the use effect is better. At the same time, when in use, the motor 16 can be started to drive the gear 18 to rotate.
