Description

Technical Field

[0001] The utility model belongs to the technical field of mass flowmeters, and in particular relates to a buffer diverter of a mass flowmeter. Background Art

[0002] A mass flow meter is an instrument that can directly measure the mass flow rate of a fluid in a closed pipe and the density of the medium, and then derive the measured fluid mass;

[0003] Since the impact of the water flow on the mass flowmeter is large during the measurement, the measurement structure is affected. Therefore, in the application number: CN202322630310.9, a mass flowmeter buffer diverter is disclosed, which includes a fixed pipe, a detection meter is fixedly connected to the fixed pipe, a connecting pipe is fixedly connected to the bottom wall of the fixed pipe, a diverter is fixedly connected between the connecting pipes, and the diverter is arranged in a "U" shape. The outer fixed sleeve of the connecting pipe is provided with a fixed flange, and the fixed flange is arranged at the connection between the connecting pipe and the diverter. A fixed block is slidably arranged on the inner side wall of the connecting pipe, and a fixed groove is provided on the side of the fixed block away from the inner wall of the connecting pipe, and a buffer plate is arranged on the fixed groove. The utility model is provided with a buffer plate, which can rotate when the fluid flows into the diverter to buffer it, and the buffer plate will move with the fluid to further buffer it, and with the cooperation of the damper, the vibration of the diverter can be weakened, thereby reducing the impact on the detection, which is beneficial to the use of the device.

[0004] The above structure then plays a buffering role on the water flow, but when buffering, it is mainly buffered by the cooperation of the spring and the buffer. However, since the spring and other structures are exposed to the outside world, the impact of the subsequent water flow will cause it to be corroded by impurities in the water, and then cause the set spring to rust and damage, which is not suitable for long-term use.

[0005] Therefore, how to provide a buffer diverter for a mass flow meter is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 FIG. 1 is a schematic diagram of a structure of a buffer diverter of a mass flow meter provided by an embodiment of the utility model, comprising:

[0031] Fixed tube 1;

[0032] Buffer tubes 2, wherein the buffer tube 2 array is installed at the bottom of the fixed tube 1;

[0033] A shunt pipe 3, which is movably mounted at the lower end of the buffer pipe 2;

[0034] A magnetic buffer structure, which is arranged in the middle of the buffer tube 2;

[0035] An inner rubber ring 4, which is arranged on the inner side of the magnetic buffer structure;

[0036] The rotating structure is arranged in the middle of the inner rubber ring 4 .

[0037] In the embodiment of the utility model, when in use, the liquid will impact the rotating structure, thereby causing the height of the inner rubber ring 4 to drop, thereby driving the height of the magnetic buffer structure to drop, thereby providing buffering;

[0038] By setting up a magnetic buffer structure, when liquid passes through, the impact it generates will be reduced by the magnetic force, so that the impact generated by the liquid is weakened. Moreover, since the magnetic buffer structure does not come into direct contact with the liquid when working, it avoids the situation where it fails due to corrosion by the liquid.

[0039] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the utility model, the rotating structure includes a supporting slide rod 12 and a center column 13, a slide groove 10 is opened at the top of the inner side of the inner rubber ring 4, the supporting slide rod 12 is slidably installed in a circular array on the top of the slide groove 10, the center column 13 is fixedly installed in the middle of the supporting slide rod 12, and a spiral blade 14 is fixedly installed on the surface of the lower end of the center column 13.

[0040] In the embodiment of the utility model, when in use, when the liquid reaches the top of the spiral blade 14, it then spirals down along it, and drives the spiral blade 14 to slide in the slide groove 10 at the top of the inner rubber ring 4 through the support slide rod 12 on the surface of the central column 13 in the middle;

[0041] By providing a rotating structure, the impact of the falling liquid is converted into the power of the spiral blade 14 to rotate, further offsetting the impact of the falling liquid, thereby improving the buffering effect on the liquid.

[0042] like Figure 2 , Figure 3 , Figure 4 ,and Figure 5As shown, as a preferred embodiment of the utility model, the magnetic buffer structure includes an outer rubber ring 6, a lifting groove 9 is opened in the inner wall of the buffer tube 2, and a through hole 5 is opened in the inner circumferential array of the buffer tube 2. The outer rubber ring 6 is movably arranged inside the lifting groove 9, and is fixedly connected to the outer side of the inner rubber ring 4 through the through hole 5. A permanent magnet 7 is placed inside the outer rubber ring 6, and an electromagnet 8 is arranged at the lower end of the buffer tube 2.

[0043] In the embodiment of the utility model, when the liquid flows, the height of the outer rubber ring 6 is lowered through the inner rubber ring 4, and the electromagnet 8 is started at the same time to generate a magnetic force with the same magnetic force as the bottom of the permanent magnet 7 inside the outer rubber ring 6 for buffering;

[0044] A permanent magnet 7 is placed inside the outer rubber ring 6, and an electromagnet 8 is arranged at the lower end of the buffer tube 2. This prevents the magnet from directly contacting the liquid, causing erosion and failure.

[0045] like Figure 2 and Figure 4 As shown, as a preferred embodiment of the present utility model, the positions of the permanent magnet 7 and the electromagnet 8 correspond to each other, and the magnetic forces of the facing surfaces of the permanent magnet 7 and the electromagnet 8 are the same.

[0046] In the embodiment of the utility model, when in use, by making the positions of the permanent magnet 7 and the electromagnet 8 correspond, and the magnetic forces of the facing surfaces of the permanent magnet 7 and the electromagnet 8 are the same, the distance between the two can be controlled, thereby achieving the effect of magnetic buffering.

[0047] like Figure 2 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present utility model, a leakage hole 11 is provided in a circumferential array at the bottom of the slide groove 10 , and the width of the bottom of the supporting slide rod 12 is the same as the width of the slide groove 10 .

[0048] In the embodiment of the utility model, when in use, leakage holes 11 are provided in a circumferential array at the bottom of the slide groove 10 to facilitate the flow of liquid, and the width of the bottom of the supporting slide rod 12 is made the same as the width of the slide groove 10 to facilitate sliding.

[0049] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the present invention, the diameter of the spiral blade 14 is the same as the inner diameter of the inner rubber ring 4 , and the height of the spiral blade 14 is equal to the thickness of the inner end of the inner rubber ring 4 .

[0050] In the embodiment of the utility model, when in use, the diameter value of the spiral blade 14 is made the same as the inner diameter value of the inner rubber ring 4, so that the liquid is in full contact with it, and the height value of the spiral blade 14 is equal to the thickness value of the inner rubber ring 4, so that the liquid can drive the spiral blade 14 to rotate.

[0051] The above embodiment of the utility model provides a buffer diverter for a mass flow meter. When in use, the liquid will flow from the fixed tube 1 through the buffer tube 2 to the diverter tube 3. When passing through the buffer tube 2, the liquid will first contact the surface of the spiral blade 14, so that the spiral blade 14 drives the inner rubber ring 4 to descend, and then drives the outer rubber ring 6 to descend through the through hole 5.

[0052] When the liquid flows, the electromagnet 8 is activated at the same time, so that it generates a magnetic force that is the same as the magnetic force at the bottom of the permanent magnet 7 inside the outer rubber ring 6, and then the spiral blade 14 is offset by the magnetic force due to the impact of the liquid and the downward movement, thereby achieving a buffering effect;

[0053] At the same time, when the liquid passes and reaches the top of the spiral blade 14, it then spirals down along it, and drives the spiral blade 14 to slide in the slide groove 10 at the top of the inner rubber ring 4 through the support slide rod 12 on the surface of the central column 13 in the middle, thereby converting the impact of the falling liquid into the power of the spiral blade 14 to rotate, further offsetting the impact caused by the falling liquid, thereby improving the buffering effect on the liquid.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
