Description
Technical field
The utility model relates to a kind of round pressure container perimeter change tester, is mainly used in the perimeter change of test round pressure container pressurization front and back, belongs to the pressure vessel testing technical field.
Background technology
Pressure vessel belongs to explosive dangerous material, and can this series products must carry out applied voltage test in design and after accomplishing processing, reach design pressure and operate as normal to check it.At present; Domestic pressure container production producer mainly contains two kinds of methods to the test of round pressure container perimeter change: before (1) test; Binding round a circle steel tape on the pressure vessel circumference, the size of record circumference is after pressure is elevated to predetermined value; The circumferential size of record this moment, at last with twice circumferential size subtract each other just obtain pressurizeing before and after the variable quantity of pressure vessel girth.The method is simple to operate, and is low and cost is not high to staff's technical requirement, but precision is difficult to satisfy requirement of engineering.(2) before the test, the whole circumference adhering resistance strainometer in the pressure vessel upper edge is connected strainometer through lead with strainmeter, after pressure is elevated to predetermined value, obtains the strain on the whole circumference and draws the variable quantity of whole pressure vessel girth through conversion.The method is owing to use strainometer to measure, the precision engineering demands, but test causes testing cost higher with the not reproducible use of strain ga(u)ge; Simultaneously, adopt strain measurement technology, operator's professional technique is had relatively high expectations.
Summary of the invention
The utility model provides a kind of operation, lower-cost round pressure container perimeter change tester be convenient to, and satisfies the requirement of engineering precision, reduces the professional technique requirement to the operator.
The technical scheme of the utility model is: round pressure container perimeter change tester; Comprise dial gauge 1, adjustable push rod 2, spring 3, chain 5, adjustable push rod chuck 6, dial gauge chuck 7, upper connecting rod 8, lower connecting rod 9; Adjustable push rod 2 is installed on respectively in adjustable push rod chuck 6 and the dial gauge chuck 7 with dial gauge 1, and the front end of adjustable push rod 2 and dial gauge 1 passes corresponding chuck madial wall and withstand relatively the termination; The position is provided with peg 10 to adjustable push rod chuck 6 up and down, outer openend is provided with upper connecting rod 8 and lower connecting rod 9 with dial gauge chuck 7 the inners; Spring 3 is loaded on the peg 10 at adjustable push rod chuck 6 and dial gauge chuck 7 inner positions up and down; Chain 5 two ends are placed on upper connecting rod 8 and the lower connecting rod 9, adjustable push rod chuck 6 and dial gauge chuck 7, spring 3, chain 5, dial gauge 1 and the adjustable push rod 2 common test frames that form.Through the position of the adjustable push rod 2 of threaded adjusting, the enforcement of dial gauge is pushed up in advance, change through preparatory top dial gauge generation reading and realize the perimeter change measurement.
The place, four end angles of adjustable push rod chuck 6 and dial gauge chuck 7 is provided with and is used to adjust its stable lifting screw 4.Upper connecting rod 8 is a snap ring structure with lower connecting rod 9 junctions, and chain 5 two ends are placed on the snap ring of upper connecting rod 8 and lower connecting rod 9 junctions.To guarantee the stable of chain.Can connect through the socket mode between upper connecting rod 8 and the lower connecting rod 9, or alternate manners connections such as screw thread, welding, also can be an one-piece construction.
The utility model utilize chain self rigidity big, with the good characteristics of circumference stickiness; With its variation of transmitting the pressure vessel girth as bindiny mechanism, two chucks are installed at the chain two ends, connect through spring between two dishes; On one of them chuck dial gauge is installed; Another installs push rod, package unit is fixedly mounted on the pressure vessel circumference through chain and spring, again through measuring the perimeter change amount that pressurization front and back dial gauge reading just can obtain the round pressure container.
The utility model can make things convenient for, test out intuitively the situation of change of round pressure container girth before and after pressurization, and its test result precision is enough to engineering demands.
