Abstract
The utility model relates to a shock absorption and noise elimination device on a fluid transportation pipeline. The shock absorption and noise elimination device is characterized in that a Pi-shaped shock absorption and noise elimination connector mainly composed of horizontal pipes and vertical pipes is fixedly connected to the fluid transportation pipeline. The shock absorption and noise elimination device has the advantages that the manufactured Pi-shaped connector is installed on the fluid transportation pipeline, shock generated by process equipment on the pipeline is transmitted along the pipeline, when the shock passes through the Pi-shaped connector, the shock can be effectively eliminated, noise can be reduced and eliminated, and therefore other pipeline equipment can be protected against shock.
Description
Technical field
The utility model belongs to fluid-transporting tubing, relates in particular to the vibration-damping noise-reducing device on a kind of fluid-transporting tubing.
Background technique
In fluid-transporting tubing and relevant device, take transport gas medium pipeline as example, in natural gas line course of conveying, generally adopt pressure governor and modulating valve to control natural gas transport pressure, pressure governor can produce vibrations and noise in decompression process, vibrations and noise are passed to the flowmeter instrument place in upstream or downstream along pipeline, measuring accuracy to flowmeter exerts an influence (as the most responsive in ultrasonic flowmeter), causes the accuracy of measuring to decline, and causes damage.
Model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, vibration-damping noise-reducing on a kind of fluid-transporting tubing device is provided, between pressure governor and flowmeter, adopts vibration-damping noise-reducing device, can effectively reduce vibrations conduction, eliminate noise, guarantee the measuring accuracy of flowmeter.
The utility model for achieving the above object, by the following technical solutions: the vibration-damping noise-reducing device on a kind of fluid-transporting tubing, it is characterized in that: mainly by transverse tube and vertical tube, form π type vibration-damping noise-reducing joint, described π type vibration-damping noise-reducing joint is fixed on fluid-transporting tubing.
Described π type vibration-damping noise-reducing joint comprises four equal tees and four pipe caps, and described equal tee connects into π type vibration-damping noise-reducing joint by vertical tube respectively, and described four pipe caps are fixed in respectively the termination of equal tee along media flow direction.
Described π type vibration-damping noise-reducing joint wherein three with the affixed pipe cap of equal tee in horizontal direction, the affixed pipe cap of one of them and equal tee in vertical direction, and is located at the outlet end of media flow direction.Can better realize noise reflection loss.
Two affixed transverse tubes of equal tee below described π type vibration-damping noise-reducing joint, and be connected with fluid-transporting tubing by adpting flange.
Beneficial effect: by the π type jiont treatment of making on fluid-transporting tubing; the vibrations that on pipeline, process device produces are along pipeline transmission; when by π type joint, can effectively eliminate vibrations and noise attentuation is eliminated, to protect other line equipment not to be subject to its vibration influence.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is π type joint noise reduction shock absorption principle figure.
In figure: 1, equal tee, 2, pipe cap, 3, vertical tube, 4, adpting flange, 5, transverse tube.
Embodiment
Below in conjunction with preferred embodiment, describe embodiment of the present utility model in detail.
Refer to accompanying drawing 1, the utility model provides the device of the vibration-damping noise-reducing on a kind of fluid-transporting tubing, mainly by transverse tube and vertical tube, forms π type vibration-damping noise-reducing joint, and described π type vibration-damping noise-reducing joint is fixed on fluid-transporting tubing.Described π type vibration-damping noise-reducing joint in the present embodiment, adopt four equal tees 1 and four pipe caps 2, described equal tee connects into π type vibration-damping noise-reducing joint by vertical tube 3 respectively, and described four pipe caps are fixed in respectively on the termination of equal tee along media flow direction.
Refer to accompanying drawing 1, the utility model preferred version is, the bottom-up direction of described π type vibration-damping noise-reducing joint is followed successively by: the equal tee of horizontal positioned wherein three with the affixed pipe cap of equal tee in horizontal direction, the affixed pipe cap of one of them and equal tee in vertical direction, and is located at the outlet end of media flow direction.The affixed transverse tube 5 of two equal tees below described π type vibration-damping noise-reducing joint, and be connected with fluid-transporting tubing by adpting flange 4.Can better realize noise reflection loss.
Refer to accompanying drawing 2; by the π type jiont treatment of making, on fluid-transporting tubing, the vibrations noise that on pipeline, process device produces is along pipeline transmission, when by π type joint; can effectively eliminate vibrations and reduce noise, to protect other line equipment not to be subject to its noise vibration influence.Meanwhile, because the π type structure of itself uniqueness makes it have certain compensation of pipeline function, can absorb the pipeline axial displacement and the deformation that by the temperature difference, are caused, reduce the stress that pipeline expands with heat and contract with cold and produces.This device adopts and is welded to connect, and also can adopt flange to be connected in fluid-transporting tubing.
Pipe fitting and steel pipe are welded according to pattern and the size of the figure of design, welded rear one-tenth and carried out 100% non-destructive inspection, finally make a strength test and every other verification tests, qualified rear formation product.
Through actual test and test, this device can effectively reduce noise 10-20decibel through actual test and test, and the duct length that can naturally compensate is about 15-25mm.
The above, be only preferred embodiment of the present utility model, not structure of the present utility model done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of the technical solution of the utility model.
