Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 - Figure 3 As shown in FIG. - FIG., an embodiment provided by the present utility model: an adjustable flowmeter includes a triangular pipe 1. The outer wall of the top of the triangular pipe 1 is fixedly connected with a flowmeter main body 2. An adjustment mechanism 5 is provided on the triangular pipe 1. By setting the adjustment mechanism 5, simple connection, fixation and separation of pipes of different specifications can be carried out. An auxiliary mechanism 6 is provided on the adjustment mechanism 5. By setting the auxiliary mechanism 6, fine impurities in the connecting pipe water can be blocked. The adjustment mechanism 5 includes a thread groove 51. The thread groove 51 is opened on the side outer wall of the triangular pipe 1. A groove 52 is opened on the side inner wall of the triangular pipe 1. An arc-shaped strip 54 is fixedly connected to the side outer wall of the triangular pipe 1. By setting the arc-shaped strip 54 to cooperate with the ring-shaped frame 55, the outer surface of the connecting pipe can be attached and clamped for fixation. The ring-shaped frame 55 is slidably connected to the side outer wall of the triangular pipe 1. A frosted groove 56 is opened on the side outer wall of the ring-shaped frame 55. By setting the frosted groove 56, the problem of slipping off the hand when the ring-shaped frame 55 is rotated by personnel can be reduced.

[0025] Refer to Figure 2 - Figure 4, a telescopic cotton 53 is fixedly connected to the inner wall of the side surface of the groove 52. By providing the telescopic cotton 53, the leakage of water stains outward at the connection between the connecting pipe and the triangular pipe 1 is reduced. The thickness of the telescopic cotton 53 is two millimeters. There are several arc-shaped strip plates 54, and several arc-shaped strip plates 54 are respectively fixedly connected to the outer walls on both sides of the triangular pipe 1. The annular frame 55 is threadedly connected to the inner wall of the side surface of the thread groove 51. By providing the thread groove 51, the annular frame 55 is driven to move back and forth. The annular frame 55 is slidably connected to the outer wall of the side surface of the arc-shaped strip plate 54. An indication mark 57 is provided on one outer wall of the annular frame 55. By providing the indication mark 57, the operation method is prompted. A flow display meter 3 is fixedly connected to one outer wall of the flowmeter main body 2, and a monitoring valve main body 4 is fixedly connected to the bottom outer wall of the flowmeter main body 2.

[0026] Refer to Figure 3 - Figure 4 , the auxiliary mechanism 6 includes an annular disc 61. The annular disc 61 is slidably connected to the inner wall of the side surface of the groove 52. Filter holes 62 are provided on the inner wall of the side surface of the annular disc 61. By providing the filter holes 62, the water stains passing through the triangular pipe 1 are filtered to prevent impurities from interfering with the flowmeter assembly and affecting the instrument data. A impurity collection groove 63 is provided on the inner wall of the side surface of the annular disc 61. By providing the impurity collection groove 63, the filtered impurities adhere to the impurity collection groove 63, reducing the problem that impurities adhere to the inside of the triangular pipe 1 and are inconvenient for personnel to clean, replace and maintain. There are several filter holes 62, and several filter holes 62 respectively penetrate through the inner wall of the side surface of the annular disc 61. The filter holes 62 are connected to the triangular pipe 1 in communication.

[0027] Working principle: Insert the connecting pipe into the inner wall of the groove 52 on the triangular pipe 1, so that the outer surface of the connecting pipe adheres to the telescopic cotton 53. Subsequently, rotate the annular frame 55 according to the indication mark 57, so that the annular frame 55 moves along with the thread groove 51. The annular frame 55 moves and presses the arc-shaped strip plate 54, so that the arc-shaped strip plate 54 bends inwards to adhere to and clamp the outer wall of the connecting pipe of different specifications. When the water source of the connecting pipe passes through the triangular pipe 1 during use, the impurities in the water are filtered through the filter holes 62 to prevent the impurities in the water from adhering to the monitoring valve main body 4 during long-term flow, affecting the accuracy of the flow data counted by the flowmeter main body 2. At the same time, after long-term use, by rotating the annular frame 55, the arc-shaped strip plate 54 is loosened, so that the arc-shaped strip plate 54 is separated from the outer wall of the connecting pipe, and the connecting pipe is separated from the triangular pipe 1. Subsequently, take out the annular disc 61 from the groove 52, put a new annular disc 61 into the groove 52, and then re-insert the connecting pipe into the inner wall of the groove 52 to adhere to the outer surface of the annular disc 61 to complete the replacement and maintenance.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
