Description

Technical Field

[0001] This utility model belongs to the field of flow meter technology, specifically relating to flow meter housings, and more particularly to turbine flow meter housings and protective structures for housings. Background Technology

[0002] In the field of industrial measurement, flow meters are widely used for monitoring and controlling fluids in pipelines. Their housings are usually directly connected to the pipeline via flanges and bolts to achieve sealing and fixation.

[0003] However, in practical applications (especially in outdoor environments), flow meters need to be disassembled regularly for calibration, maintenance, or repair. Frequent disassembly and assembly can lead to wear on bolts and protective layers, which in turn reduces the fastening force between the housing and the pipeline. Loosening of the flow meter housing connection can pose a risk of vibration or even leakage under high pressure, corrosive media, or large temperature variations.

[0004] Therefore, how to solve the problem of reduced fastening force between the shell and the pipe due to frequent disassembly and assembly is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one turbine flow meter housing and a protective structure for the housing to solve the technical problem of reduced fastening force between the housing and the pipeline due to frequent disassembly and assembly.

[0007] In a first aspect, embodiments of this disclosure provide a turbine flow meter housing, including a flange disposed at the end of a pipeline and the housing; a plurality of bolts disposed in mounting holes of the flange; a protective structure sleeved on the nuts and / or bolts, and including: a base gasket disposed on the mounting side of the nuts and / or bolts, and the side of the base gasket facing the mounting side having multiple sealing portions circumferentially from the center outward.

[0008] In one optional embodiment, the multiple sealing part includes a rigid ring embedded in the concentric end face of the base gasket and forming a first annular protrusion that abuts against the exposed surface of the flange; the base gasket is provided with a cavity, which has at least one concentric annular groove on the side facing the nut / or bolt; wherein, when the nut / or bolt is adapted to move toward the flange, the rigid ring moves into the cavity, thereby reducing the cavity volume, so as to drive the gas to make the annular groove protrude outward from the cavity, forming a second annular protrusion that abuts against the exposed surface.

[0009] In one alternative embodiment, the outer periphery of the base pad is provided with an annular barrier, which is adapted to wrap around the outer periphery of the nut / screw to reduce water flow trapped around the nut / screw.

[0010] In one alternative embodiment, the opening edge of the annular enclosure is provided with an extension ring, one end of which is a slope, the slope being adapted to disperse water flow.

[0011] In one alternative embodiment, the base pad and the annular enclosure are integrally molded structures made of rubber or silicone.

[0012] Secondly, embodiments of this disclosure also provide a protective structure for a housing, comprising: a base pad disposed on the mounting side of the bolt's nut and / or bolt, the mounting side of the base pad being used to abut against the exposed surface of the flange; and an annular barrier disposed on the outer periphery of the base pad, the annular barrier being adapted to wrap around the outer periphery of the nut and / or bolt to reduce water flow retained on the outer periphery of the nut and / or bolt.

[0013] In one alternative embodiment, the bottom pad has multiple sealing portions circumferentially arranged from the center outward on the side facing the mounting side; wherein the multiple sealing portions are adapted to enhance the sealing between the flange and the end face of the nut / or bolt.

[0014] In one optional embodiment, the multiple sealing part includes a rigid ring embedded in the concentric end face of the base gasket and forming a first annular protrusion that abuts against the exposed surface; the base gasket has a cavity with at least one concentric annular groove on the side facing the nut / or bolt; wherein, when the nut / or bolt is adapted to move toward the flange, the rigid ring moves into the cavity, reducing the cavity volume, thereby driving gas to cause the annular groove to bulge outward from the cavity, forming a second annular protrusion that abuts against the exposed surface.

[0015] In one alternative embodiment, the opening edge of the annular enclosure is provided with an extension ring, one end of which is a slope, the slope being adapted to disperse water flow.

[0016] In one alternative embodiment, the base pad and the annular enclosure are integrally molded structures made of rubber or silicone.

[0017] This utility model provides a turbine flow meter housing. The beneficial effects of this utility model are:

[0018] By installing a protective structure on the end faces of the nut and bolt, the bottom gasket is pressed between the end faces of the flange and the nut / or bolt, forming a multi-layered sealing part that enhances the compressive force between the end faces of the flange and the nut / or bolt, improves the sealing performance of the nut and bolt position, prevents corrosive liquid from entering the bolt connection surface from the gap, effectively solves the problem of bolt corrosion, and thus stabilizes the fastening force between the shell and the pipeline.

[0019] By setting up a ring-shaped enclosure, the sidewalls of the nuts or bolts can be wrapped to prevent water from accumulating on the sidewalls, further preventing water from entering the bolt connection surface and causing corrosion, thus improving the sealing effect.

[0020] By setting an annular groove, when the nut is tightened, the distance between the nut and the bolt decreases, and the gas, which is thinner, rushes towards the annular groove, causing it to bulge towards the mounting side to form a second annular protrusion that abuts against the exposed surface. This, in turn, cooperates with the rigid ring to form a multi-ring seal, and the sealing performance becomes stronger as the extrusion pressure increases.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] like Figures 1 to 4 As shown, some embodiments provide a housing for a turbine flow meter, including a flange 2, which is disposed at the end of the pipeline and the housing 1. The flange 2 on the opposite side of the pipeline and the housing 1 is abutted by bolts 3. Specifically, a plurality of bolts 3 are disposed in the mounting holes 22 of the flange 2. A protective structure 4 is disposed on the nuts 31 and / or nuts 32 of the bolts 3. The protective structure 4 includes a bottom gasket 41, which is disposed on the mounting side of the nuts 31 and / or nuts 32 of the bolts 3, that is, the side facing the flange 2. The bottom gasket 41 facing the mounting side has multiple sealing parts 43 arranged from the center outward. The multi-layer sealing parts enhance the compressive force between the flange 2 and the end faces of the nuts 31 and / or nuts 32, improve the sealing performance of the nut 31 and / or nuts 32, prevent corrosive liquid from entering the connection surface of the bolts 3 from the gaps, effectively solve the problem of bolt 3 being corroded, and thus stabilize the fastening force between the housing 1 and the pipeline.

[0037] like Figure 3 and Figure 4 As shown, to further enhance the sealing performance of bolt 3, an annular barrier 42 is provided on the outer periphery of the base gasket 41. This barrier is adapted to wrap around the outer periphery of nut 31 / or nut 32 to reduce water flow stagnating on the outer periphery of nut 31 / or nut 32. An extension ring 44 is provided on the opening edge of the annular barrier 42, one end of which is a slope 441, which is adapted to disperse water flow.

[0038] It should be further explained that the base pad 41 and the annular barrier 42 are integrally molded structures made of rubber or silicone. During installation, the base pad 41 needs to be passed through the bolt 3, and one side of the base pad 41 needs to be moved to abut against the nut 31 or nut 32. At this time, the annular barrier 42 can wrap around the side wall of the nut 31 or nut 32 to prevent water from accumulating on the side wall of the nut 31 or nut 32, and further prevent water from entering the bolt 3 connection surface and causing corrosion.

[0039] The composition and structure of the multiple sealing part 43 are described in detail below. The multiple sealing part 43 includes a rigid ring 432, which is embedded in the concentric end face of the base pad 41, as shown below. Figure 3 As shown, in its natural state, the rigid ring 432 is partially enclosed within the base gasket 41 and suspended on the mounting side of the base gasket 41, forming a first annular protrusion 434 that abuts against the exposed surface 21 of the flange 2. The base gasket 41 contains a cavity 431, with at least one concentric annular groove 433 on the side facing the nut 31 / or nut 32. When the nut 31 / or nut 32 is adapted to move towards the flange 2, the rigid ring 432 moves into the cavity 431, reducing the volume of the cavity 431. This drives the gas to cause the annular groove 433 to protrude outward from the cavity 431, forming a second annular protrusion 435 that abuts against the exposed surface 21. Figure 4 As shown, when the nut 32 locks the bolt 3, the distance between the nut 31 and the nut 32 decreases. At this time, the rigid ring 432 will move in the direction of F1 under the squeezing action of the exposed surface 21. When the rigid ring 432 moves into the cavity 431, the volume of the cavity 431 decreases, and the gas will rush towards the position of the annular groove 433 with a thinner thickness, in the direction of F2, so that it protrudes towards the mounting side to form a second annular protrusion 435 that abuts against the exposed surface 21, and then cooperates with the rigid ring 432 to form a multi-ring seal. As the squeezing pressure increases, the sealing performance becomes stronger.

[0040] Some embodiments provide a protective structure for the housing, including: a base gasket 41 disposed on the mounting side of the nut 31 and / or nut 32 of the bolt 3, the mounting side of the base gasket 41 being used to abut against the exposed surface 21 of the flange 2; an annular barrier 42 disposed on the outer periphery of the base gasket 41, the annular barrier 42 being adapted to wrap around the outer periphery of the nut 31 and / or nut 32 to reduce water flow trapped around the outer periphery of the nut 31 and / or nut 32; the base gasket 41 and the annular barrier 42 are integrally molded structures made of rubber or silicone.

[0041] The base gasket 41 has multiple sealing portions 43 arranged from the center outward on the side facing the mounting side; wherein, the multiple sealing portions 43 are adapted to enhance the sealing between the flange 2 and the end faces of the nut 31 / or nut 32. The multiple sealing portions 43 include a rigid ring 432, which is embedded in the concentric end face of the base gasket 41 and forms a first annular protrusion 434 that abuts against the exposed surface 21; a cavity 431 is provided inside the base gasket 41, and at least one concentric annular groove 433 is formed on the side facing the nut 31 / or nut 32; wherein, when the nut 31 / or nut 32 is adapted to move towards the flange 2, the rigid ring 432 moves into the cavity 431, thereby reducing the volume of the cavity 431, so as to drive gas to make the annular groove 433 protrude outward from the cavity 431, forming a second annular protrusion 435 that abuts against the exposed surface 21.

[0042] The opening edge of the annular enclosure 42 is provided with an extension ring 44, one end of which is a slope 441, which is suitable for dispersing water flow.
