Description

Technical Field

[0002] In the water supply system, accurately measuring the flow rate in the water supply pressure pipe is a crucial task. Most of the existing water supply pressure pipe flow meters are fixedly installed, and the measurement requires professional operation, and the water supply needs to be stopped or the water pressure needs to be reduced, which brings inconvenience to the normal operation of the water supply system. In addition, the existing flow meters have the disadvantages of being large in size, heavy in weight, and not easy to carry, which makes it difficult to meet the needs of on-site measurement and monitoring of water supply pipes;

[0003] For example, the patent with publication number CN217304052U discloses a portable electromagnetic flowmeter. By positioning the adapter hole and the positioning hole through the positioning column, the connection stability and convenience of the connecting plate and the positioning sleeve can be high, so that the first positioning seat and the second positioning seat can position the electromagnetic flowmeter body with high convenience in carrying and loading. The overall structure is simple, easy to use, and has high practicality.

[0004] When the electromagnetic flowmeter is carried, the above device is mainly fixed and adjusted through the positioning holes and the positioning columns. Since there is a distance between the positioning holes, there is a gap in the clamping of the flowmeter during adjustment and fixing, which makes the electromagnetic flowmeter unstable when carried. In addition, the above device only clamps the bottom of the flowmeter. In actual use, the flowmeter may rotate along the positioning seat. Therefore, a portable water supply pressure pipeline flowmeter is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means for realizing the utility model, creative features, objectives and effects easy to understand, the utility model is further explained below in conjunction with specific diagrams. In the description of the utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, an integral connection or a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be internal communication between two components.

[0019] Example 1

[0020] like Figure 1-2 and Figure 4 A portable water supply pressure pipeline flowmeter shown in the figure includes a flowmeter 1, a flange 2 and a measuring tube 4. The bottom of the flowmeter 1 is connected to the measuring tube 4. There are two flanges 2, and the two flanges 2 are respectively connected to the two ends of the measuring tube 4. When flow measurement is performed, the pipeline to be measured is placed in the flow tube, and the flowmeter 1 can be turned on to perform measurement. A clamping mechanism for clamping and fixing the measuring tube 4 is provided at the two ends of the two flanges 2 that are far apart. The flowmeter 1 can be clamped and fixed by the clamping mechanism to maintain its stability when carried.

[0021] In this embodiment, the clamping mechanism includes a positioning seat 3, a positioning frame 1 5, a positioning frame 2 6, a bolt 8, a fixing clamp 1 15 and a fixing clamp 2 16. There are two positioning seats 3, and the positioning frame 1 5 and the positioning frame 2 6 are respectively connected to one of the positioning seats 3. The positioning frame 1 5 is "L"-shaped, and the positioning frame 2 6 is "I"-shaped. The positioning frame 1 5 cooperates with the positioning frame 6. The longer end of the positioning frame 1 5 is consistent with the length of the positioning frame 2 6. The positioning frame 1 5 is provided with a threaded blind hole 9, and the positioning frame 2 6 is provided with a threaded through hole 10. The threaded blind hole 9 is arranged at the shorter end of the positioning frame 1 5. The threaded blind hole 9 corresponds to the threaded through hole 10. The bolt 8 is threadedly connected to the threaded blind hole 9 and the threaded through hole 10. When the flow meter 1 is clamped, the threaded blind hole 9 is aligned with the threaded through hole 10, and then Screw the bolt 8 into the threaded through hole 10 and the threaded blind hole 9 in sequence, and tighten the bolt to make the positioning frame 1 5 and the positioning frame 2 6 fit tightly and not shake. The fixing clamp 1 15 is connected to the positioning frame 2 6, and the fixing clamp 2 16 is connected to the positioning frame 1 5. The fixing clamp 15 is connected to a block 18 on the side facing the positioning frame 1 5, and the fixing clamp 2 16 is provided with a plurality of slots 17 on the side facing the positioning frame 2 6. The slots 17 and the blocks 18 cooperate with each other. When the position between the positioning frame 1 5 and the positioning frame 2 6 is tightened and fixed, the blocks 18 on the fixing clamp 1 15 will be inserted into the slots 17 on the fixing clamp 2 16, and the outer wall of the block 18 will fit tightly with the inner wall of the slot 17 to clamp the upper part of the flow meter 1 to prevent the flow meter 1 from rotating up and down when the flow meter 1 is carried.

[0022] Furthermore, a protective sleeve 7 is provided on the outer wall of the shorter end of the positioning frame 5. When the flow meter 1 is carried, the flow meter 1 can be lifted by grabbing the positioning frame 5. The provision of the anti-slip sleeve 7 can increase the friction between the hand and the positioning frame 5, thereby facilitating the carrying of the flow meter 1.

[0023] Example 2

[0024] like Figure 2-3 A portable water supply pressure pipeline flowmeter 2 is shown, and a limiting groove 13 is provided on the positioning seat 3. The inner center of the limiting groove 13 is connected to the limiting column 11. The side wall of the limiting groove 13 fits tightly with the outer wall of the flange 2, and the outer wall of the limiting column 11 fits tightly with the side wall of the flange 2. One end of the flange 2 is placed in the positioning seat 3, and the limiting column 11 and the limiting groove 13 can limit it. In conjunction with the positioning seat 3 at the other end, the position of the flange 2 can be limited between the two positioning seats 3.

[0025] The outer wall of the limiting column 11 is sleeved with a rubber ring 12, and the inner wall of the limiting groove 13 is connected with a rubber ring 2 14. When the flange 2 is placed in the positioning seat 2 and then carried, the rubber ring 12 and the rubber ring 2 14 can prevent the flange 2 from directly contacting it, thereby preventing the flange 2 from being damaged due to the friction between the flange 2 and the positioning seat 3 during carrying.

[0026] The process flow and working principle of the utility model are as follows: when the flow meter 1 needs to be carried, the flow meter 1 only needs to be placed between the two positioning seats 3, and the flanges 2 on both sides of the flow meter 1 are aligned with the limiting columns 11 and the limiting grooves 13, so that the side walls of the flanges 2 are tightly fitted with the outer walls of the limiting columns 11, and the outer walls of the flanges 2 are tightly fitted with the side walls of the limiting grooves 13. At this time, the position of the flow meter 1 is limited between the two positioning seats 3, and then the threaded through holes 10 on the positioning frame 1 5 are aligned with the threaded blind holes 9 on the positioning frame 2 6, and the bolts 8 are screwed into the threaded through holes 10 and the threaded blind holes 9 in turn and tightened. At this time, the block 18 on the fixing clamp 15 will be inserted into the slot 17 on the fixing clamp 16, so that the upper part of the flow meter 1 can be clamped to prevent the flow meter 1 from rotating in the vertical direction. When the flow meter 1 is carried, the flow meter 1 will not shake in the surrounding and vertical directions, thereby achieving the effect of improving the stability of the flow meter 1 when it is carried.
