[0034] The flushing assembly of the embodiment of the present invention is provided with a first water outlet and a second water outlet on the flushing ring. The first water outlet obtains the water supply of the first water inlet and guides the flushing water to be discharged obliquely, so as to clean the end of the differential pressure transmitter after the flushing ring is installed, thereby ensuring the detection accuracy and sensitivity of the differential pressure transmitter. The second water outlet obtains the water supply of the second water inlet and guides the flushing water to be discharged along the axial direction of the flushing ring, so as to effectively flush the inner wall of the pressure taking pipe after the flushing ring is installed, thereby ensuring the cleaning effect of the pressure taking pipe.

[0035] In some embodiments, the flushing ring 1 includes a ring body 13 and a connector 14. The ring body 13 is a ring-shaped body extending in the left-right direction. One end of the connector 14 is an interface end, and the other end is a threaded end. The threaded end of the connector 14 is arranged in the ring wall of the ring body 13 along the radial direction of the ring body 13 and is threadedly connected to the ring wall of the ring body 13. The interface end of the connector 14 is located on the outer periphery of the ring body 13, preferably protruding from the outer peripheral surface of the ring body 13, for connecting to a water supply pipeline. There are preferably two connectors 14, and the two connectors 14 are arranged at intervals along the circumference of the ring body 13. Preferably, one of the connectors 14 is arranged at the top of the ring body 13, and the other connector 14 is arranged at the bottom of the ring body 13. The inner cavity of the top connector 14 serves as the first water inlet 11, and the inner cavity of the bottom connector 14 serves as the second water inlet 12.

[0036] In some embodiments, the first water outlet portion 2 is a water outlet pipe having a pipe connecting end 21 and a pipe water outlet end 22 that are relatively arranged. The pipe connecting end 21 is arranged at the inner circumferential end of the flushing ring 1 and is connected to the first water inlet 11. The water outlet pipe or the pipe water outlet end 22 extends along the radial direction of the flushing ring 1 and is arranged obliquely along the axial direction of the flushing ring 1.

[0037] like Figure 1 As shown, the first water outlet portion 2 is a water outlet pipe, the upper end of the water outlet pipe is a pipe connecting end 21, and the lower end of the water outlet pipe is a pipe water outlet end 22. The pipe connecting end 21 extends in the vertical direction and is connected to the inner circumference of the flushing ring 1. Preferably, the top joint 14 passes through the ring body 13 in the vertical direction, the bottom surface of the top joint 14 is flush with the inner circumference of the ring body 13, and the pipe connecting end 21 is welded to the bottom surface of the top joint 14 and the inner circumference of the ring body 13. The pipe connecting end 21 is connected to the first water inlet 11 to obtain water supply from the first water inlet 11. The pipe water outlet end 22 extends from top to bottom and is arranged obliquely from right to left, so as to guide the flushing water supplied by the first water inlet 11 through the pipe water outlet end 22 and discharge obliquely from top to bottom and from right to left.

[0038] It can be understood that the pipe connecting end is not limited to being welded to the bottom surface of the top joint and the inner circumference of the ring body. In other embodiments, the bottom surface of the top joint is located within the ring wall of the ring body, the top of the pipe connecting end is provided with an external thread, the top of the pipe connecting end extends into the ring wall of the ring body and is threadedly connected to the ring wall of the ring body, and the bottom of the top joint and the top of the pipe connecting end are located in the same mounting hole of the ring body.

[0039] It is understood that the structure of the water outlet pipe is not limited to Figure 1 In the structure shown, in other embodiments, the water outlet pipe extends from top to bottom and is tilted from right to left. In other words, the pipe connecting end and the water outlet end of the pipe both extend from top to bottom and are tilted from right to left.

[0040] In some embodiments, the first water outlet portion 2 is a water outlet hole provided on the inner circumferential surface of the flushing ring 1. The water outlet hole has a hole connecting end and a hole water outlet end that are relatively arranged. The hole connecting end is connected to the first water inlet 11. The water outlet hole or the water outlet end extends along the radial direction of the flushing ring 1 and is inclined along the axial direction of the flushing ring 1.

[0041] like Figure 2 As shown, the first water outlet part 2 is a water outlet hole provided on the inner circumference of the flushing ring 1, the upper end of the water outlet hole is the hole connecting end, and the lower end of the water outlet hole is the hole water outlet end. The top joint 14 extends from top to bottom into the ring wall of the ring body 13, and the bottom surface of the top joint 14 is located in the ring wall of the ring body 13. The bottom of the first water inlet 11 is opposite to and connected with the hole connecting end, so that the water outlet hole obtains the water supply of the first water inlet 11. The water outlet hole as a whole extends radially along the flushing ring 1 and is tilted along the axial direction of the flushing ring 1. In other words, the water outlet hole as a whole extends from top to bottom and is tilted from right to left to guide the flushing water supplied by the first water inlet 11 to be discharged obliquely from top to bottom and from right to left.

[0042] It is understood that the structure of the water outlet is not limited to Figure 2 In the structure shown, in other embodiments, the hole connecting end extends in the up-down direction, the hole outlet end extends from top to bottom, and is tilted from right to left, and the flushing water supplied by the first water inlet is guided through the hole outlet end to be discharged tilted from top to bottom and from right to left.

[0043] In some embodiments, the inner diameter of at least one water outlet end of the first water outlet portion 2 decreases along the direction of the medium flowing in the first water outlet portion 2 .

[0044] Specifically, the first water outlet part 2 may have an overall inner diameter that decreases along the direction of flushing water flowing in the first water outlet part 2 , or the inner diameter of one end of the first water outlet part 2 may decrease along the direction of flushing water flowing in the first water outlet part 2 .

[0045] like Figure 1 As shown, the inner diameter of the pipe connection end 21 is constant, and the inner diameter of the pipe outlet end 22 decreases along the direction of the flushing water flow therein, thereby increasing the impact force of the flushing water and improving the cleaning effect. It is understood that in other embodiments, the inner diameter of the outlet pipe as a whole can also decrease along the direction of the flushing water flow therein. In other words, the inner diameters of both the pipe connection end and the pipe outlet end decrease along the direction of the flushing water flow.

[0046] like Figure 2 As shown, the inner diameter of the water outlet hole decreases along the direction of the flushing water flow therein, thereby increasing the impact force of the flushing water and improving the cleaning effect. It is understood that in other embodiments, the inner diameter of the hole connection end can be constant, and the inner diameter of the hole outlet end can decrease along the direction of the flushing water flow therein.

[0047] In some embodiments, the second water outlet portion 3 is an elbow, which includes a connected radial portion 31 and an axial portion 32. The radial portion 31 extends radially along the flushing ring 1. The radial portion 31 is arranged at the inner circumferential end of the flushing ring 1 and is connected to the second water inlet 12. The axial portion 32 extends axially along the flushing ring 1, and an axial water outlet 33 is provided at the end of the axial portion 32.

[0048] like Figure 1 and Figure 2 As shown, the second water outlet portion 3 is an elbow, which includes a radial portion 31, a curved portion and an axial portion 32 connected in sequence. The radial portion 31 extends in the up-down direction, and the axial portion 32 extends in the left-right direction. The curved portion is arc-shaped and is connected between the top end of the radial portion 31 and the left end of the axial portion 32.

[0049] The bottom joint 14 extends vertically through the ring body 13, with the top surface of the bottom joint 14 flush with the inner circumference of the ring body 13. The radial portion 31 is welded to the top surface of the bottom joint 14 and the inner circumference of the ring body 13 and communicates with the second water inlet 12 formed by the bottom joint 14 to receive flushing water supplied by the second water inlet 12. An axial water outlet 33 is provided at the right end of the axial portion 32. Flushing water supplied from the second water inlet 12 enters the axial portion 32 through the radial portion 31 and the curved portion, and is then discharged rightward through the axial water outlet 33 under the guidance of the axial portion 32.

[0050] Preferably, the axial portion 32 is coaxially arranged with the ring body 13. In other words, the axial portion 32 is arranged on the center line of the ring body 13 so that the flushing water discharged from the axial water outlet 33 acts evenly on the inner wall of the pressure taking pipe 5 connected to the right end of the flushing ring 1.

[0051] It is understandable that the structure of the second water outlet is not limited to Figure 1 and Figure 2 As shown, in other embodiments, the elbow serving as the second water outlet includes a radial portion and an axial portion connected in sequence. In other words, the elbow is L-shaped, or the elbow serving as the second water outlet includes a curved portion and an axial portion connected in sequence, and the bottom of the curved portion is connected to the inner circumference of the ring body.

[0052] In some embodiments, the inner diameter of at least one end of the axial portion 32 provided with the axial water outlet 33 decreases along the direction in which the medium in the axial portion 32 flows.

[0053] like Figure 1 and Figure 2 As described above, the inner diameter of the right end of the axial portion 32 decreases from left to right, so that the inner diameter of the axial water outlet 33 decreases, thereby increasing the impact force of the flushing water discharged from the axial water outlet 33 to improve the cleaning effect.

[0054] Preferably, the inner diameter of the axial water outlet 33 is 6 mm to 10 mm, preferably 8 mm.

[0055] It can be understood that the inner diameter of the axial portion is not limited to the right end decreasing from left to right. In other embodiments, the inner diameter of the axial portion decreases from left to right.

[0056] In some embodiments, a wall surface of the axial portion 32 is provided with a plurality of radial water outlets 34 , and the radial water outlets 34 penetrate the wall surface of the axial portion 32 along the radial direction of the flushing ring 1 .

[0057] like Figure 1 and Figure 2 As shown, a radial water outlet 34 is provided on the wall of the axial portion 32. The radial water outlet 34 penetrates the wall of the axial portion 32 in the radial direction of the flushing ring 1. In other words, the radial water outlet 34 penetrates the wall of the axial portion 32 in the radial direction of the axial portion 32. A portion of the flushing water in the axial portion 32 is discharged to the right through the axial water outlet 33, and another portion of the flushing water is discharged in the radial direction of the flushing ring 1 through the radial water outlet 34. The flushing water discharged from the radial water outlet 34 is used to flush the inner circumference of the ring body 13 and / or the inner circumference of the pressure-taking pipe 5 located at the left end of the axial water outlet 33 to avoid the existence of a flushing dead angle.

[0058] Preferably, the inner diameter of the radial water outlet 34 is 1 mm to 3 mm, preferably 2 mm.

[0059] In some embodiments, there are multiple groups of radial water outlets 34 , which are arranged at intervals along the axial direction of the flushing ring 1 , and each group of radial water outlets 34 includes multiple radial water outlets 34 arranged at intervals along the circumference of the flushing ring 1 .

[0060] like Figure 1 and Figure 2 As shown, there are five groups of radial water outlets 34, and the five groups of radial water outlets 34 are arranged at intervals along the left-right direction. Each group of radial water outlets 34 includes four radial water outlets 34 arranged at intervals around the left-right direction to ensure that the flushing water is evenly applied by the radial water outlets 34 to the inner circumference of the flushing ring body 13 and / or the inner circumference of the pressure taking pipe 5 located at the left end of the axial water outlet 33.

[0061] In some embodiments, the axial portion 32 extends from the radial portion 31 to the outside of the surrounding space of the flushing ring 1, and the radial water outlet 34 is provided in the portion of the axial portion 32 located outside the surrounding space, or, a portion of the radial water outlet 34 is provided in the portion of the axial portion 32 located outside the surrounding space, and another portion of the radial water outlet 34 is provided in the portion of the axial portion 32 located within the surrounding space.

[0062] like Figure 1 and Figure 2As shown, the axial portion 32 extends rightward from the curved portion and extends outside the surrounding space of the flushing ring 1. After the flushing ring 1 is connected to the pressure pipe 5, the axial portion 32 extends into the pressure pipe 5. The leftmost set of radial water outlets 34 is located in the surrounding space of the flushing ring 1 for flushing the inner circumference of the ring body 13. The remaining four sets of radial water outlets 34 are located inside the pressure pipe 5 for flushing the inner circumference of the pressure pipe 5.

[0063] It can be understood that in other embodiments, all radial water outlets may be located in the pressure taking pipe.

[0064] like Figure 1 and Figure 2 As shown, the detection device of the embodiment of the present utility model includes a flushing component, a differential pressure transmitter 4 and a pressure taking pipe 5.

[0065] The flushing assembly is the flushing assembly of the embodiment of the present invention. A differential pressure transmitter 4 is disposed at one axial end of the flushing ring 1, with the first water outlet 2 directed toward the differential pressure transmitter 4. A pressure pipe 5 is disposed at the other axial end of the flushing ring 1, with the second water outlet 3 directed toward the lumen of the pressure pipe 5.

[0066] Specifically, such as Figure 1 and Figure 2 As shown, the left end of the ring body 13 is provided with a differential pressure transmitter 4, which includes a connecting flange 41 and a diaphragm 42. The connecting flange 41 is connected to the left end of the ring body 13, and the right end of the connecting flange 41 is provided with a diaphragm 42. The diaphragm 42 is located within the space surrounding the ring body 13. The first water outlet 2 is positioned toward the diaphragm 42 to guide flushing water to flush the diaphragm 42, thereby ensuring the detection accuracy and sensitivity of the differential pressure transmitter 4. The right end of the ring body 13 is provided with a pressure pipe 5, which is coaxially arranged and connected to the ring body 13. The second water outlet 3 extends into the lumen of the pressure pipe 5 to guide flushing water to flush the inner circumference of the pressure pipe 5.

[0067] Furthermore, a sealing ring is provided between the connecting flange 41 and the ring body 13 , and a sealing ring is also provided between the pressure taking pipe 5 and the ring body 13 .

[0068] It can be understood that the second water outlet is not limited to extending into the lumen of the pressure-taking pipe. In other embodiments, the ring body has a larger axial dimension, and the second water outlet is located in the ring body.

[0069] It should be noted that the differential pressure transmitter can be used as a flow meter or a liquid level meter.

[0070] The detection device of the embodiment of the present invention connects the flushing component of the embodiment of the present invention between the differential pressure transmitter and the pressure taking pipe, so as to clean the end of the differential pressure transmitter through the first water outlet, thereby ensuring the detection accuracy and sensitivity of the differential pressure transmitter, and effectively flushing the inner wall of the pressure taking pipe through the second water outlet, thereby ensuring the cleaning effect of the pressure taking pipe.
