Description
Technical field
The present invention relates to be used to measure the oil pocket of fluid volume change.
Background technology
In the hydraulic system of some precision assemblies, often need accurately to record the volume change of fluid.The mode of measuring the fluid volume change is a lot, and these modes all are to realize by the flow through fluid volume of pipeline of indirect detection mostly, and the flow velocity of the oil liquid leakage of the pipeline of flowing through and fluid often all can have influence on the precision of measurement.
Summary of the invention
The purpose of this invention is to provide a kind of variable quantity that directly utilizes the fluid volume as Controlling Source, realize the oil pocket of high-acruracy survey fluid volume change.
The present invention is achieved by the following technical programs.
The oil pocket that is used to measure the fluid volume change comprises by the band round-ended cylinder, the cylindrical shell of cylindric lid and the securing member formation that is connected cylinder and lid, be provided with in the cylindrical shell cylindrical shell is separated into, the rolling diaphragm of following two cavitys, the circumferential edge of rolling diaphragm is pressed fixing by cylinder and lid, be fixed with sleeve with the cylinder coaxial cable in the bottom surface of lower chamber, be equipped with the piston rod that is slidingly matched in the sleeve, the top of piston rod and the center fixation of cap-shaped piston, the upper surface of cap-shaped piston and the one side of rolling diaphragm are gluing, the another side of rolling diaphragm is with dull and stereotyped gluing, the space of round movable part between cap-shaped piston outer wall and cylinder inner wall of rolling diaphragm, be symmetrical in sleeve in the bottom surface of cylinder displacement transducer is installed, the measuring steel wire of displacement transducer links to each other with the inner top surface of piston, the signal wire of displacement transducer is drawn outside the cylindrical shell, has fluid at the center of lid and imports and exports.
During work, upper cavity is as annular seal space, lower chamber is as measuring the chamber, import and export from fluid when the fluid of seal chamber inside and to flow to when flowing out, piston can the lifting along with the increase and decrease of fluid volume, the length of the measuring steel wire of displacement transducer can elongate or shorten thereupon, thereby makes the output voltage generation linear change of displacement transducer.Because displacement transducer is highly sensitive instrument, even the micro displacement variable quantity also can make output voltage change, its variation precision is up to the millivolt level, thereby can accurately record the variable quantity of fluid volume.
The oil pocket compact conformation of measurement fluid volume change of the present invention, simple, with low cost, do not need power source, can directly utilize the volume change of fluid to obtain measuring-signal, and the variable quantity of the fluid volume mode with electric signal directly sent out, oil pocket of the present invention can be used to measure the hydraulic oil, pure water of various models and other rubber not had the volume change of corrosive liquid, easy to operate and its measuring accuracy height.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
With reference to Fig. 1, be used to measure the oil pocket of fluid volume change, comprise by band round-ended cylinder 6, cylindric lid 1 and is connected the cylindrical shell that the securing member 5 of cylinder 6 and lid 1 constitutes.In the illustrated example, the nozzle end of band round-ended cylinder 6 has the evagination plane of a loop, securing member 5 is for having the cylinder of internal thread, one end of this cylinder has the corresponding internal projecting ring of the evagination plane of a loop plane with band round-ended cylinder 6, lid 1 has with securing member 5 twists the external thread that connects, tighten by screw thread, make cylinder 6 and lid 1 be tightened to one.In cylindrical shell, be provided with the rolling diaphragm 4 that cylindrical shell is separated into upper and lower two cavitys 13,14, here, the nozzle of cylindric lid 1 is along the groove 16 that circumferentially has the edge embedding of holding rolling diaphragm 4, the circumferential edge of rolling diaphragm 4 embeds in the groove 16 of lid 1, play the effect of zero RunddichtringO, thereby realized the sealing between lid 1, rolling diaphragm 4 and the cylinder 6.Be fixed with sleeve 9 with cylinder 6 coaxial cables in the bottom surface of lower chamber 14, be equipped with the piston rod 8 that is slidingly matched in the sleeve 9, the top of piston rod 8 is by the center fixation of no header stud 7 with cap-shaped piston 3, the one side of the upper surface of cap-shaped piston 3 and rolling diaphragm 4 is gluing, the another side of rolling diaphragm 4 is gluing with dull and stereotyped 2, can guarantee the flatness of rolling diaphragm 4 bottom surfaces like this.The space of the round movable part of rolling diaphragm 4 between cap-shaped piston 3 outer walls and cylinder 6 inwalls, usually make dull and stereotyped 2 area be slightly larger than the area of piston 3 upper surfaces, its edge is bent downwardly a little, fasten the bottom edge of rolling rolling diaphragm 4, thereby make rolling diaphragm 4 can touch the inwall motion of piston 3 and cylinder 6 well; And the longitudinal section that makes cap-shaped piston 3 is trapezoidal, helps moving back and forth of rolling diaphragm, and after each to-and-fro movement finishes, makes rolling diaphragm 4 restore to the original state the serviceable life of having improved whole oil pocket.In motion process, sleeve 9 play the guiding role, and has avoided causing stuck phenomenon owing to the skew of piston.Be symmetrical in sleeve 9 in the bottom surface of cylinder 6 two displacement transducers 10 are installed, the measuring steel wire 11 of displacement transducer links to each other with the inner top surface of piston 3, and the signal wire 12 of displacement transducer is drawn outside the cylindrical shell.Fluid is imported and exported 15 centres of opening at lid 1, has avoided the too fast impact that causes dull and stereotyped 2 of oil flow, causes moving component to tilt, to such an extent as to stuck.
