Abstract
The utility model provides a pipe bundle type fluid rectifier, which comprises an outer shell, a pipe bundle core which is arranged in the outer shell, a positioning component which is positioned between the outer shell and the pipe bundle core, an axial seal strip base which is fixed on the outer side of the pipe bundle core and a seal strip which is inlaid in the axial seal strip base and tightly matched with the inner wall of the outer shell. The utility model has the advantages of simple structure, low cost, long service life and convenient use. The utility model is arranged in front of a fluid metering device and is used for eliminating unsteady flow state to improve the metering accuracy, and is suitable for the fluid rectification before metering of operation of natural gas, petroleum, city gas, etc.
Description
The utility model relates to a kind of fluid rectifier, particularly relates to a kind of bundled tube fluid rectifier.
At present, the apparatus for metering fluids that oil, natural gas, gas system use is not with rectifier basically, stablizes but various apparatus for metering fluids all requires to measure preceding flowing medium fluidised form, and asymmetric unstable fluidised forms such as pulsed flow, rotating flow must not be arranged.Particularly present widely used orifice plate measuring apparatus, rank, whirlpool measuring apparatus and precession vortex measuring apparatus, very high to the requirement of fluidised form degree of stability, otherwise can make the detection flow be lower than actual flow, thus cause the certain economic loss.Also there is employing 19 to manage tube bank rectifiers abroad and comes stabilization of fluidized, closely cooperate, be quite difficult to eliminate, thereby the popularization of bundled tube fluid rectifier and use are very limited along restraining circumferential rotating flow but will make to reach between tube bank and the shell.
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of efficient, low-cost bundled tube fluid rectifier is provided.
The utility model bundled tube fluid rectifier is to realize like this, it comprises shell, tube bank core in the enclosure is set, positioning element between shell and tube bank core, fixedly be to restrain the axial seal bar seat in the core outside, be embedded in the axial seal bar seat and with the close-fitting Stamping Steel Ribbon of outer casing inner wall.The termination of shell can be set to flange arrangement, is convenient to be connected with fluid-transporting tubing; The tube bank core is gathered together by high-precision some pipes and constitutes, as adopts 19 pipes, and the tube bank core has two kinds of arrangement modes, i.e. triangle dislocation is arranged and triangular planar shape pipe is arranged; Positioning element can be that axially locating flange, jackscrew or location are fast, is used to restrain core axially locating in the enclosure; Axial seal bar seat is generally 6, and isometric with the tube bank core, evenly is welded on the tube bank core outside, the axial seal bar seat outside has seal groove, and Stamping Steel Ribbon is embedded in the seal groove, and Stamping Steel Ribbon is generally soft sealing strip, its cross section can be different shape, as O shape, D shape.X-shaped or ladder etc.In the time of in the tube bank core is packed shell into, the Stamping Steel Ribbon shutoff gap between tube bank core and the shell, eliminated along the circumferential rotating flow of tube bank core, simultaneously because Stamping Steel Ribbon is a soft sealing strip, certain elasticity is arranged, can compensate between tube bank core and the shell because the gap that machining error caused.
The working principle of the utility model bundled tube fluid rectifier is, during use, is installed between apparatus for metering fluids and the fluid delivery tube, and promptly an end is connected with fluid delivery tube, and the other end is connected with apparatus for metering fluids.Fluid flows into rectifier from delivery pipe, forms stabilization of fluidized after tube bank core combing, and incoming fluid measuring apparatus again is to guarantee the accuracy of metering.
The advantage of the utility model bundled tube fluid rectifier is simple in structure, cost is low, long service life, easy to use, before being installed in measuring apparatus, be used for eliminating the unstable state that flows,, be applicable to the preceding fluid rectification of metering of operations such as rock gas, oil, gas to improve measuring accuracy.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
