Description

Technical Field

[0001] The utility model belongs to the technical field of reciprocating compressors, and particularly relates to a self-sealing vibration damping orifice plate structure. Background Art

[0002] A reciprocating compressor is an important mechanical equipment in oil refining and chemical plants. When the reciprocating compressor works, the piston makes periodic reciprocating movements in the cylinder, which causes the suction and exhaust to be intermittent and periodic, and the gas in the pipe is in a pulsating state. When the pulsating air flow encounters components such as elbows, reducing pipes, control valves or blind plates, an exciting force that changes with time will be generated. Under the action of this exciting force, the pipeline will vibrate. And because the pressure pulsation always exists, it is normal for the reciprocating compressor pipeline to vibrate to a certain extent within the allowable range, but violent vibration should be avoided, otherwise it may cause pipeline damage.

[0003] At present, when strong pipeline vibration occurs on site, the simplest and most feasible vibration damping method is generally to add a vibration damping orifice plate structure. The traditional vibration damping orifice plate structure usually sets gaskets on both end faces of the orifice plate, and the end faces of the two gaskets away from the orifice plate abut against the flange of the two pipe orifices. However, since this vibration damping orifice plate structure is assembled and installed by multiple parts, once the fasteners on the pipeline are loosened due to the high-speed operation of the reciprocating compressor, there will be a risk of multiple leaks. Summary of the Utility Model

[0004] The utility model provides a self-sealing vibration damping orifice plate structure to overcome the defects of the prior art, which can reduce the risk of multi-point leakage.

[0005] The purpose of the utility model is realized by the following technical solutions:

[0006] A self-sealing vibration damping orifice plate structure, which includes a plate body for fastening and connecting between the flanges of two pipe orifices. A through hole for communicating with two channels is axially arranged on the plate body, and metal extension convex rings located outside the channels are integrally arranged on both end faces of the plate body.

[0007] In one embodiment, the metal extension convex ring includes a convex block integrally arranged on the plate body in a ring shape, and a metal extension layer is arranged at one end of the convex block away from the plate body.

[0008] In one embodiment, the metal extension layer is a copper alloy layer electroplated on one end of the convex block.

[0009] In one embodiment, the surface roughness of the copper alloy layer is less than 0.8um.

[0010] In one embodiment, the thickness of the metal extension layer is 0.2mm - 0.3mm, and the width of the metal extension layer is 10mm - 70mm.

[0011] In one embodiment, the plate body is a stainless steel plate.

[0012] In one embodiment, the thickness of the plate body is 3 - 6 mm.

[0013] In one embodiment, the plate body is coaxially connected to the two pipe orifice flanges, the through hole is coaxially arranged on the plate body, and the aperture of the through hole is smaller than the aperture of the channel.

[0014] In one embodiment, a plurality of fasteners are circumferentially and tightly connected between the pipe orifice flanges, and the outer diameter of the plate body matches the diameter of the inscribed circle of the plurality of fasteners.

[0015] In one embodiment, a straight edge is provided at the end of the through hole.

[0016] The beneficial effects of the present utility model are as follows:

[0017] The metal extension convex ring has metal ductility. After it is tightly connected between the two pipe orifice flanges along with the plate body, the metal extension convex ring can reach a certain deformation amount under the pre-tightening effect, so that the two metal extension convex rings respectively closely fit the end faces of the two pipe orifice flanges, thereby realizing the sealing effect; and the self-sealing vibration damping orifice plate structure does not require an additional gasket, which effectively reduces the risk of multi-point leakage.

[0023] In the drawings, the same components are denoted by the same reference numerals. The drawings are not drawn to actual scale.

[0024] Reference Numerals:

[0025] 1 - plate body, 2 - compressor system flange, 3 - pipeline system flange, 4 - pipe clamp, 5 - metal extension convex ring, 501 - convex block, 502 - metal extension layer, 6 - through hole, 7 - fastener, 8 - straight edge. Detailed Embodiments

[0026] The present utility model will be further described below in conjunction with the accompanying drawings.

[0027] The present utility model provides a self-sealing vibration damping orifice plate structure, as Figure 1 and Figure 2 shown, which includes a plate body 1 for tightly connecting between two pipe flange openings. A through hole 6 for communicating with two channels is axially arranged on the plate body 1. Metallic extension convex rings 5 located outside the channels are integrally arranged on both end faces of the plate body 1.

[0028] It can be understood that the metallic extension convex rings 5 have metallic extensibility. After the plate body 1 is tightly connected between two pipe flange openings, the metallic extension convex rings 5 can reach a certain deformation amount under the pre-tightening action of fasteners 7 such as bolts, so that the two metallic extension convex rings 5 respectively closely adhere to the end faces of the two pipe flange openings, thereby realizing the sealing function; and the self-sealing vibration damping orifice plate structure does not require an additional gasket, which effectively reduces the risk of multi-point leakage.

[0029] It should be noted that the two pipe flange openings can be respectively the pipeline system flange 3 and the compressor system flange 2.

[0030] In addition, compared with the traditional vibration damping orifice plate structure, the structure of the present utility model is simple, scientifically reasonable in design and convenient to use, and can be directly installed between the original traditional compressor system flange 2 and the pipeline system flange 3 to achieve the purpose of quick and convenient installation and replacement.

[0031] In one embodiment, as Figure 3 shown, the metallic extension convex ring 5 includes a convex block 501 integrally arranged in a ring shape on the plate body 1, and a metallic extension layer 502 is arranged at one end of the convex block 501 away from the plate body 1.

[0032] In one embodiment, the metallic extension layer 502 is a copper alloy layer electroplated on one end of the convex block 501.

[0033] It should be noted that the copper alloy used for the copper alloy layer can be copper-zinc alloy or tin bronze, and the copper alloy has good plasticity and metallic extensibility.

[0034] In one embodiment, the surface roughness of the copper alloy layer is less than 0.8 um.

[0035] It should be noted that after the copper alloy layer is electroplated on the convex block 501, the surface of the copper alloy layer can be polished to make its surface roughness less than 0.8 um, so as to be more conducive to achieving the sealing effect.

[0036] In one embodiment, the thickness of the metallic extension layer 502 is 0.2 mm to 0.3 mm, and the width of the metallic extension layer 502 is 10 mm to 70 mm.

[0037] In one embodiment, the plate body 1 is a stainless steel plate. Correspondingly, the bump 501 is also made of stainless steel.

[0038] In one embodiment, the thickness of the plate body 1 is 3 - 6 mm.

[0039] In one embodiment, the plate body 1 is coaxially connected to the two pipe orifice flanges. The through hole 6 is coaxially arranged on the plate body 1, and the aperture of the through hole 6 is smaller than the aperture of the channel.

[0040] It can be understood that since the through hole 6 is coaxial with the channel and the aperture of the through hole 6 is smaller than the aperture of the channel, the through hole 6 has a flow limiting effect.

[0041] In one embodiment, as Figure 4 shown, a plurality of fasteners 7 are tightly connected circumferentially between the pipe orifice flanges, and the outer diameter of the plate body 1 matches the diameter of the inscribed circle of the plurality of fasteners 7.

[0042] It should be noted that the fastener 7 here refers to a bolt, and the inscribed circle here refers to the inscribed circle of the rod parts of the plurality of bolts.

[0043] It can be understood that the rod parts of the plurality of bolts arranged circumferentially can jointly restrict the outside of the plate body 1, so that the plate body 1 is always coaxial with the compressor system flange 2 and the pipeline system flange 3, thereby effectively controlling the smooth flow of the air flow in the channel of the pipeline system.

[0044] In one embodiment, a straight edge 8 is provided at the end of the through hole 6. Specifically, the end of the through hole 6 maintains a sharp acute angle.

[0045] It should be noted that by setting it like this, the gas pulsation in the pipeline system can be effectively eliminated to achieve the purpose of reducing the vibration of the pipeline system.

[0046] In addition, a pipe clamp 4 is provided in the pipeline system to enhance the stiffness of the pipeline system.

[0047] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
