Description
Technical Field
The utility model relates to a belong to electric power system equipment technical field, in particular to automatic one-way oil recovery syringe that seals.
Background
In the field oil chromatography oil extraction work of the transformer, the traditional glass needle cylinder is adopted for extracting oil at present. And after the oil sample is taken, the oil sample is carried to a laboratory for analysis and detection of the dissolved gas of the transformer oil. The detection work has higher requirements on oil samples, and the needle cylinder is required to be filled with the oil samples, so that small bubbles cannot exist. However, in the field oil chromatography sampling work, the sample is taken, and in the sealing process of the glass syringe, the sealing property at the joint of the needle opening and the rubber plug is difficult to ensure, and air is easily introduced due to the untight sealing. When the sample is transported back to the laboratory with a vehicle after sampling, the leak-tight seal also leads to air infiltration. In the oil chromatography sampling specification, the introduction of air is clearly stated, which leads to inaccuracy in the analysis of the sample. A reliable hermetic oil chromatography sampling vessel is therefore needed.
Disclosure of Invention
Therefore, the utility model provides an automatic one-way oil recovery syringe that seals can prevent effectively that gas from getting into, improves sealed effect, and convenient operation safety passes through sample analysis's accuracy.
The technical scheme of the utility model is realized like this:
the utility model provides an automatic one-way oil recovery syringe that seals, include oil storage mechanism and cup joint the connection mouth at oil storage mechanism front end, the inside front end of connection mouth is equipped with the sealing plug, the center of sealing plug is equipped with into oil pipe, the oil outlet has been seted up on the sealing plug, the inside tail end of connection mouth is equipped with out oil pipe, advance oil pipe pass through the oil outlet with go out oil pipe intercommunication, go out oil pipe with oil storage mechanism communicates with each other, oil seal plug cup joints and covers the elastic sleeve of oil outlet.
Preferably, the oil storage mechanism is a syringe, and the connecting nozzle is sleeved with the front end of the syringe.
Preferably, the front end of the connecting nozzle is provided with an oil extraction port, and the oil extraction port is communicated with the oil inlet pipe.
Preferably, the connecting nozzle is made of rubber.
Preferably, the elastic sleeve is a rubber tube.
Preferably, the oil outlet is formed in the top end of the sealing plug.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides an automatic one-way oil recovery syringe that seals will connect mouth and external oil recovery mouth butt joint, and the oil body enters into in the oil pipe and washes out the elastic sleeve pipe through outside oil feed pressure from oil outlet department again, is pressed into in the oil storage mechanism through an oil pipe again. After oil extraction is finished, the elastic sleeve loses oil inlet pressure and clings to the sealing plug again and blocks the oil outlet hole, and sealing effect is finished. The inside design that can only advance of connection mouth can effectively prevent gaseous entering, simultaneously, utilizes rubber elastic deformation's principle to realize the high sealed of degree of seal, and convenient operation safety connects the mouth and directly registrates with oil storage mechanism, can take off the connection mouth after getting back to the laboratory, or directly from advancing oil pipe department injection gas, carries out experimental analysis.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only preferred embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without inventive effort.
Fig. 1 is a schematic view of the internal structure of the present invention;
fig. 2 is the internal structure diagram of the middle connection nozzle of the present invention.
In the figure, 1 connecting nozzle, 2 sealing plugs, 3 oil inlet pipes, 4 oil outlet holes, 5 oil outlet pipes, 6 elastic sleeves, 7 injectors and 8 oil extraction ports.
Detailed Description
In order to better understand the technical content of the present invention, the following embodiments are provided, and the present invention is further described with reference to the accompanying drawings.
Example one
Referring to fig. 1 to 2, the utility model provides an automatic one-way oil recovery syringe that seals, include oil storage mechanism and cup joint at the connection mouth 1 of oil storage mechanism front end, the front end of connecting 1 inside of mouth is equipped with sealing plug 2, the center of sealing plug 2 is equipped with into oil pipe 3, it communicates with each other with the front end of connecting 1 to advance oil pipe 3, oil outlet 4 has been seted up on sealing plug 2, the tail end of connecting 1 inside of mouth is equipped with out oil pipe 5, advance oil pipe 3 through oil outlet 4 with go out oil pipe 5 intercommunication, go out oil pipe 5 with oil storage mechanism communicates with each other, oil pipe 2 has cup jointed and has covered the elastic sleeve 6 of oil outlet 4.
With connector nozzle 1 and external production port butt joint, the oil body enters into the inside of sealing plug 2 through advancing oil pipe 3, and the oil body struts elastic sleeve 6 from oil outlet 4 through outside oil feed pressure this moment, and when pressure reached a definite value, elastic sleeve 6 was washed out, and the oil body enters into out oil pipe 5, is pressed into in the oil storage mechanism through out oil pipe 5 again. After the oil extraction is finished, the connecting nozzle 1 is separated from the external oil extraction port, the elastic sleeve 6 loses the oil inlet pressure and is tightly attached to the sealing plug 2 again and blocks the oil outlet 4, and the sealing effect is finished.
