Embodiment
Following conjunction with figs. and Reference numeral are done more detailed description to embodiment of the present utility model, make to have the knack of those skilled in the art and can implement according to this after studying this instructions carefully.
Fig. 1 is for showing the three-dimensional explosive view according to the flowmeter with magnetic pointer of the utility model preferred embodiment.As shown in Figure 1, comprise according to flowmeter of the present utility model: a transparent cylindrical shell 10, a fixed bar 20, a magnetic float 30 and a magnetic pointer 40.Have a passage in the transparent cylindrical shell 10, and its two ends have one first opening 11 and one second opening 12.Wherein, a graduation apparatus 13 is shown on the outside surface of transparent cylindrical shell 10.Fixed bar 20 is arranged in the passage, and first opening 11 and second opening, 12 places are fixed in by a fixation kit 21,22 respectively in its two ends.Magnetic float 30 is sheathed on the fixed bar 20 slidably, and is restricted between the fixation kit 21,22.Magnetic pointer 40 is slidably mounted on the mounting structure of transparent cylindrical shell 10 lateral surfaces, and is arranged at the position that can be attracted by magnetic float 30.
As Fig. 1 and shown in Figure 2, first opening 11 of transparent cylindrical shell 10 of the present utility model and second opening, 12 places further are equiped with the one first prominent portion 51 and one second that connects that interconnects with passage and prominently meet portion 52, and first opening 11 and second opening, 12 places further are equiped with one first collar 513 and one second collar 523 in the mode that is spirally connected.See through this kind mode, first prominent connect portion 51, second prominent connect portion 52, fixation kit 21,22 and fixed bar 20 can be fixed in transparent cylindrical shell 10.In addition, fixation kit 21,22 is sheathed in first opening 11 and second opening 12, and has a plurality of holes on the fixation kit 21,22, can pass through smoothly to guarantee fluid.The first prominent portion 51 and second that connects prominently meets portion 52 and can be connected with the pipeline (not being shown among the figure) of outside, makes fluid also record the flow of fluid by this by the passages in the transparent tube body 10.Wherein, fixation kit 21,22 and the inner peripheral surface of transparent cylindrical shell 10 between further be provided with a packing ring 211,221; Packing ring 211,221 can prevent that fluid from leaking outside from flowmeter and exterior line joint.
In preferred embodiment of the present utility model, as shown in Figure 2, magnetic pointer 40 further comprises a transparent tube body 41 and a magnet assembly 42, wherein, transparent tube body 41 is installed on by at least one installation component on the mounting structure of transparent cylindrical shell 10, and magnet assembly 42 then is mounted slidably in transparent tube body 41.At this, the outside surface of the mounting structure self-induced transparency cylindrical shell 10 of transparent cylindrical shell 10 outward extending is installed plate body 170, and it has a rectangular groove 171; 40 on magnetic pointer sees through two fasteners 43 and is fixed in the groove 171 that plate body 170 is installed.It should be noted that; configuration and the fixed form of magnetic pointer 40 are not limited thereto; anyly be installed on transparent cylindrical shell 10 lateral surfaces and can be attracted by magnetic float 30, and then make the operator can judge easily that the magnetic pointer of magnetic float 30 positions all belongs in the protection category of the present utility model.
In addition, further be equiped with the pointer 70 of at least two adjustable positions in the groove 171 on the installation plate body 170 of the present utility model.The operator can be separately fixed at two indexs 70 position that needs, and uses as the index of flow upper and lower limit; Thus, the operator need only guarantee the magnet assembly 42 of magnetic pointer 40 between two pointers 70, just can reach the purpose of traffic monitoring easily.
The side cutaway view for the flowmeter assembled according to preferred embodiment of the present utility model that Fig. 3 is shown.As Fig. 1, shown in Figure 3, the flowmeter with magnetic pointer after assembling according to above-mentioned configuration, the first prominent portion 51 and second that connects that can see through prominently meets portion 52 and is connected with exterior line, make fluid enter from second opening, 12 places and promote magnetic float 30 in the flowmeter, the direction that indicates as arrow, make magnetic float 30 float because of fluid institute applied pressure, and then leave flowmeter from first opening 11.When measuring general transparent fluid, the operator can come the flow value of interpretation fluid directly through the graduation apparatus 13 on the transparent cylindrical shell 10 and the position of magnetic float 30.When measuring muddy fluid, though the fluid visibility in the pipeline is not good, but because the magnetic of magnetic float 30 can attract the magnet assembly 42 of magnetic pointer 40, even if the operator can't directly judge the position of magnetic float 30, still can be easily obtain the flow value of fluid by magnet assembly 42 and graduation apparatus 13.In addition, by the design of index 70, the operator need only guarantee the magnetic pointer between two pointers 70, just can carry out monitoring maximum and minimum flow easily.
Really solved the shortcoming that existing area flow meter can't measure muddy fluid easily according to the flowmeter with magnetic pointer of the present utility model, in addition, flowmeter compared to electronic type, also lack the demand for electricity and sensor, and then increased security and the fiduciary level of flowmeter itself.Moreover compared to the area flow meter of reaching same purpose by other physical construction, volume of the present utility model is less, needs the part of sealing less, not only can save the space, also is not easy to cause the seepage of fluid.
As seen from the above embodiment, value on the true tool industry of flowmeter with magnetic pointer provided by the utility model, yet above narration only is preferred embodiment explanation of the present utility model, all those skilled in the art can do other all improvement according to above-mentioned explanation, but these changes still belong in spirit of the present utility model and the following claim that defines.
