Abstract
The invention relates to a tightening device communicated with multiple osmometers, and the device is mainly applied in the mechanical property inspection technology of a monitoring instrument of vibrating wire osmometer. The device has a pedestal which is provided with hole sites of osmometers, and the bottom of the pedestal is connected to a pressure device, the pressure pipeline of which is introduced into the osmometer hole sites. The key technique lies in that: more than one osmometer hole site is installed on the pedestal, within which the pressure pipeline is located, and the pressure pipeline is connected to a communicating pipe which is equipped with branch pipes introduced into each osmometer hole site; a cover plate is mounted over the osmometer hole sites, and the central section of the cover plate is provided with orifices corresponding to the osmometer hole sites, and two sides of the orifices are equipped with upper screw holes, while lower screw holes corresponding to the upper screw holes are disposed at two sides of the osmometer hole sites on the pedestal, and tightening screws with nuts are placed into the upper and lower screw holes. With a pedestal of multiple communicated osmometer hole sites, the device of the invention can detect multiple osmometers successfully at one time, so that the working efficiency is greatly improved, and the placement of osmometers is simplified, thus saving time and labor.
Description
Technical field:
Be communicated with polynary osmometer tightening device, be mainly used in the tightening device in the monitoring instrument vibrating wire piezometer mechanical properties test technology.
Background technology:
The existing tightening device that is used for monitoring instrument vibrating wire piezometer mechanical properties test technology has base, on base, has position, osmometer hole, and the base bottom connects pressue device, and it exists following defective to overcome:
1, twice ring-shaped rubber girdle ring is arranged in the middle and upper part, osmometer wants to get into position, osmometer hole must pass through this twice barrier, and the osmometer thickness of pipe only has 1-2mm thick, is very much sharp.In the process that osmometer is pressed into, must guarantee vertically fully, otherwise there is inclination the situation that the side is cut broken rubber ring and is difficult to again discover just can occur slightly, only, could find the damage of rubber girdle ring having added after leakage of oil appears in certain pressure.Extract osmometer then, change the rubber girdle ring, insert again again, so back and forth, just can normally detect until oil-proof.
2, existing tightening device exhaust problem, error is big: because longer transparent tube is used in this tightening device and pressurized equipment junction, need hold high during exhaust, the exhaust residual volume is difficult to control, is prone to cause air content to be above standard.The ratio of compression of gas is bigger than the ratio of compression of oil, thereby causes the detection reading error big, inaccurate.
3, existing tightening device can only press from both sides an osmometer, inefficiency at every turn.
Summary of the invention:
The problem that the present invention will solve is exactly to above deficiency and provide a kind of simple in structure, easy to use, the tightening device of easy to operate, high efficiency.Its technical scheme is following:
The present invention has base, on base, has position, osmometer hole, and the base bottom connects pressue device, and pressue device has capstan to feed position, osmometer hole.Its gordian technique is to have position, an above osmometer hole on the base, in base, has capstan, and capstan connects pipe, has arm to feed each position, osmometer hole respectively on communicating pipe; Above position, osmometer hole, be provided with cover plate; Have and corresponding aperture, position, osmometer hole at the cover plate middle part; Have screw in the both sides, aperture, on base, be positioned at both sides, position, osmometer hole and have the following screw corresponding, in upper and lower screw, insert the fast ening bolt of band nut with last screw.
Compared with prior art the beneficial effect that has of the present invention is:
1, the present invention can have position, a plurality of osmometers hole to be communicated with base, can once insert many osmometers, once can successfully detect many osmometers, has improved work efficiency greatly.
2, osmometer insert simplification: the aperture of position, osmometer hole is slightly larger than the osmometer diameter, only needs steadily put into osmometer, and nut 8 to the osmometer fastening of suitably regulating fast ening bolt is loosening, time saving and energy saving.
3, use polyurethane pad with holes in bottom, position, osmometer hole, difficult compression prevents leakage of oil, does not produce the ratio of compression that is enough to influence check data simultaneously.
4, exhaust is simple: suitably pressurization make in the position, osmometer hole liquid level rise to osmometer internal cavities height (about 1～2cm), insert osmometer again, the fastening of spin nut 8 to osmometer has guaranteed that the occupation ratio of air is no more than standard, thereby has effectively reduced error.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is Fig. 1 vertical view.
Embodiment:
Referring to Fig. 1, Fig. 2, the present invention has base 2, on base 2, has position, osmometer hole 1, and base 2 bottoms connect pressue device, and pressue device has capstan 11 to feed position, osmometer hole 1.Its gordian technique is to have position, an above osmometer hole 1 on the base 2; Be provided with polyurethane pad 3 in 1 bottom, position, osmometer hole, polyurethane pad 3 middle parts are provided with hole so that to the osmometer pressurization, in base 2, have capstan 11; Capstan 11 connects pipe 10; There is arm 9 to feed each position, osmometer hole 1 respectively on communicating pipe 10, above position, osmometer hole 1, is provided with cover plate 5, have at cover plate 5 middle parts and 1 corresponding aperture 7, position, osmometer hole; Have screw in 7 both sides, aperture; On base 2, be positioned at 1 both sides, position, osmometer hole and have the following screw corresponding, in upper and lower screw, insert the fast ening bolt 6 of band nut 8, in order to fine setting fastening osmometer with last screw.Base 2 bottoms connect pressue device through screw mandrel 12, or adopt other to be flexible coupling.Base 2 be shaped as rectangular parallelepiped, square or right cylinder.
During use; Be tightened in base to screw mandrel 12, suitably pressurize, make liquid level to rise to about 1.5cm place, position, osmometer hole, insert osmometer 4 in position, osmometer hole; Add upper cover plate (osmometer stube cable line 13 pull out from cover plate aperture 7); Connect cover plate and the symmetrical upper and lower screw of base with fast ening bolt 6, regulate nut 8, it is loosening to make cover plate steadily compress the osmometer afterbody.Install all osmometers by this method, press the even stepping of osmometer range, be forced into 1.2 times of rated pressures of osmometer and reading step by step, unload step by step and be depressed into null value and reading, repeat three circulations, accomplish osmometer and detect with piston manometer.
In detection, can use the simulation osmometer to stop up idle position, hole.
