Description
Technical field
The utility model relates to liquid level gauge.
Background technology
Magnetostriction liquidometer is the high-precision liquid level measurer table, and it has steady quality, superior performance, long service life, cost performance high etc. advantage, can satisfy the measurement requirement of wide range, high precision, multiparameter simultaneously.Magnetostriction liquidometer is made up of gauge outfit, probe pipe mechanism, float, and gauge outfit is installed in probe pipe upper end, and float is installed in outside the probe pipe; Its principle of work is magnetostriction line and signal line of return that is provided with a tension in probe pipe inside, launches current impulse by the gauge outfit sensor circuit along the magnetostriction line, thereby around the magnetostriction line, forms the magnetic field of an annular; The outside liquid level float inside of probe pipe is provided with permanent-magnet steel, and its magnetic field is magnetized the magnetostriction line vertically, when two magnetic field superposition; To produce a torsional pulses at float position; This pulse is transmitted along magnetostriction alignment two ends, and an end passes to the top of probe pipe, and an end passes the bottom to the probe pipe; Initial pulse is measured with the mistiming of returning pulse, thereby confirms float position.
Magnetostriction liquidometer probe pipe mechanism is one of key mechanism of product; Magnetostriction liquidometer probe pipe mechanism was fairly simple in the past, and the magnetostriction line and the signal line of return are installed in the probe pipe after being protected by insulation sleeve, fix through the rubber sleeve and the lead fixed piece of probe pipe lower end; Rubber sleeve ends card and is fastened in the probe pipe; The lead fixed piece is installed in the rubber sleeve lower end, and the magnetostriction line passes the rubber sleeve center pit and the lead fixed piece is fixed, and magnetostriction line upper end is fixed and strained with gauge outfit.The shortcoming one of this structure is that the magnetostriction line only can rely on the elastic deformation of rubber sleeve to guarantee a tension, and the bad grasp of dynamics during assembling is drawn tight easily or broken line; The 2nd, easy ageing when rubber sleeve uses for a long time; Follow the string, can not guarantee that the magnetostriction line is in tension all the time, thereby influence measuring accuracy; Rubber sleeve can't use the application scenario at high temperature, influences the serviceability temperature scope of magnetostriction liquidometer.
The utility model content
The purpose of the utility model provides a kind of, and is rational in infrastructure, easy for installation, and insulativity and good airproof performance can guarantee that the magnetostriction line keeps the magnetostriction liquidometer probe pipe mechanism of elasticity tension.
The utility model magnetostriction liquidometer probe pipe mechanism is made up of probe pipe 1, internal lining pipe 2, tetrafluoro cover 3, lead fixed piece 4, magnetostriction line 5, backspace signal wire 6, magnetostriction line and backspace signal wire insulating sheath 7, spring 8, low head 9; Internal lining pipe 2 fixedly is inserted in probe pipe 1 bottom; The upper end of tetrafluoro cover 3 is slidingly installed on internal lining pipe 2 endoporus; Overlap 3 lower ends at tetrafluoro and be provided with armshaft 31; Armshaft 31 lower ends and probe pipe 1 endoporus of tetrafluoro cover 3 are slidingly matched, and overlap tetrafluoro between 3 armshafts 31 and internal lining pipe 2 lower ends at tetrafluoro and overlap 3 outer shroud pressure spring 8 is set, and push tetrafluoro and overlap 3 downward; Overlap 3 lower ends at tetrafluoro and offer stopping table endoporus 32; Lead fixed piece 4 is installed in tetrafluoro and overlaps in the 3 lower end endoporus 32, and magnetostriction line 5 and backspace signal wire 6 are fixed on the lead fixed piece 4 with insulating sheath 7, and low head 9 is connected with probe pipe 1 lower port welded seal.
The utility model is rational in infrastructure, and the tetrafluoro cover 3 of slidingtype drives lead fixed piece 4 under spring 8 pressure effects downward, makes magnetostriction line 5 keep stretching state; Improve measuring stability and accuracy; It is simple and convenient to produce assembling, and its temperature tolerance is good, and product serviceability temperature scope is improved.
