Description
Technical field
The present invention relates to a kind of resistance tube, specifically relate to a kind of mesh type bypass resistance pipe.
Background technique
Increasingly mature along with China's high voltage dc transmission technology, DC transmission engineering construction is in the golden period of development.In HVDC transmission system, cooling system is as the important composition of converter valve radiation system, and its runnability directly has influence on the ability to transmit electricity of whole straight-flow system.Therefore, ensure that stable, the reliable and Effec-tive Function of cooling system seems particularly important.
Converter valve water distribution system is widely used in direct-current transmission converter valve cooling, the line end of water distribution system needs to adopt bypass line gas and impurity to be taken out of and the flow of each branch road of regulating system, and the quality of its performance directly has influence on hydraulic performance and the unfailing performance of water circuit system.In practical implementation, due to the reasons such as bypass line design and use are unreasonable cause gaseous impurity cannot be discharged smoothly, waterpower is unbalanced and blocking accident is of common occurrence, therefore to the appropriate design of bypass line with select to run reliably and with long-term converter valve and seem extremely important.
The bypass resistance pipeline of current employing mainly contains two kinds, and one is the built-in conventional resistance tube of bypass line; Another is bypass blank pipe.Conventional bypass resistance pipe feature regulates waterpower effect by the internal-and external diameter and length changing resistance tube.Waterpower adjustment ability is subject to the constraint of resistance tube internal diameter, resistance tube internal diameter too small flow is too low, and gas and impurity cannot be discharged smoothly, easily cause partial discharge, the too small easy generation blocking of latus rectum simultaneously causes water head allocation uneven, and then affects the reliability of converter valve; Resistance tube internal diameter cannot realize too greatly resistance and regulate object, causes flow too much to run off and causes flow system flow unbalanced.Bypass blank pipe is applicable to the larger bypath system of flow, and because latus rectum is comparatively large, circulating resistance is less, and generally realize impedance match by bending or the mode of looping, its resistance regulating power is subject to a definite limitation.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of mesh type bypass resistance pipe, in pipe, circulation area greatly not easily blocks, resistance-adjustable, and adaptive capacity to environment is strong, is convenient to install and change simultaneously.
The object of the invention is to adopt following technical proposals to realize:
A kind of mesh type bypass resistance pipe provided by the invention, described resistance tube comprises: pipe, tube core and fixing column, and described tube core is arranged in described pipe by fixing column, and its improvements are, described tube core is vertically provided with 8 word steel rings and rotates superposition arrayed.
Wherein, the length of described 8 word steel rings is less than the internal diameter of described pipe.
Wherein, described 8 word steel ring angle of swing are 0 ° ~ 360 °.
Wherein, described 8 word steel ring angle of swing are 0 °, 45 °, 90 °, 135 °, 180 °, 225 °, 235 °, 270 °, 315 ° and 360 °.
Wherein, described 8 word steel rings rotation superposition quantity are directly proportional to the resistance criteria of described resistance tube.
Wherein, the resistance criteria of described 8 word steel ring arrayed spacing and described resistance tube is inversely proportional to.
Wherein, described pipe, tube core and fixing column are metallic material.
Wherein, described pipe, tube core and fixing column are stainless steel material.
Wherein, the two ends of described fixing column are connected with described inner tube wall and die bond respectively.
Wherein, described resistance tube is I type, L-type, S type, U-shaped, W type.
Compared with the prior art, the beneficial effect that the present invention reaches is:
1, there is good gas and impurity carries performance.
Latus rectum is comparatively large, and gas and impurity are not easy accumulation, and gas and impurity are easily taken out of by the inner turbulent flow formed.
2, there is good resistance adjusting function.
The angle adjusting 8 word steel rings rotation superpositions can must meet drag characteristic requirement very well with superposition spacing and quantity.
3, there is good environmental adaptability.
The various shapes such as I type, L-type, S type, U-shaped, W type can be designed to as requested, to meet various actual requirement of engineering.
Accompanying drawing explanation
Fig. 1 is: the axial arrangement schematic diagram of mesh type bypass resistance pipe provided by the invention;
Fig. 2 is: the radial structure schematic diagram of mesh type bypass resistance pipe provided by the invention;
Fig. 3 is: the structural representation of 8 word steel rings of mesh type bypass resistance pipe provided by the invention.
Wherein: 1, manage; 2, tube core; 3, fixing column; 4,8 word steel rings.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The present embodiment is for mesh type bypass resistance pipe, and as shown in Figure 1 to Figure 3, the mesh type bypass resistance pipe that the embodiment of the present invention provides comprises: pipe 1, tube core 2, fixing column 3,8 word steel ring 4.Pipe 1, tube core 2 and fixing column 3 are stainless steel material, and tube core 2 is vertically provided with 8 word steel rings 4 in rotating superposition arrayed, and forms mesh, tube core 2 is welded on pipe 1 inwall by fixing column 3; 8 word steel ring 4 angle of swing are set to 0 ° ~ 360 °, are preferably 0 °, 45 °, 90 °, 135 °, 180 °, 225 °, 235 °, 270 °, 315 ° and 360 °.
Wherein, the circulation area in mesh type bypass resistance pipe greatly not easily blocks, and gas and impurity are easily taken out of by the fluid of internal turbulence flowing, avoid regional area water degradation to cause conductivity to raise the partial discharge caused; Drag characteristic can be realized with superposition spacing and quantity by the angle adjusting 8 word steel rings 4 rotation superpositions according to designing requirement, the resistance of 8 word steel ring 4 arrayed spacing required for resistance tube is chosen, when resistance height, it is less that spacing is chosen, it is more that 8 word steel rings 4 superpose quantity, the path of the fluid flowing in pipe 1 is longer, and on-way resistance and collision loss are comparatively large, and it is larger that fluid runs into overall resistance; When the resistance of resistance tube is lower, it is comparatively large that 8 word steel ring 4 arrayed spacing are chosen, and 8 word steel rings 4 superpose negligible amounts, and the path of the fluid flowing in pipe 1 is shorter, on-way resistance and collision loss less, it is less that fluid runs into overall resistance.Because 8 word steel rings 4 are wrapped on tube core 2, belong to split type, resistance tube can be designed to I type, L-type, S type as requested, U-shaped, the various shapes such as W type.
Finally should be noted that: above embodiment is only in order to illustrate that technological scheme of the present invention is not intended to limit, although with reference to above-described embodiment to invention has been detailed description, those of ordinary skill in the field are to be understood that: still can modify to the specific embodiment of the present invention or equivalent replacement, and not departing from any amendment of spirit and scope of the invention or equivalent replacement, it all should be encompassed in the middle of right of the present invention.
