Abstract
The utility model relates to a novel air gun and a connection structure of the air gun. The utility model comprises an air storage tank, a cylinder sleeve, a piston, a two-position three-way electromagnetic valve and an air exhaust pipe, wherein the cylinder sleeve is connected with one end of the air storage tank, the outer end of the cylinder sleeve is connected with the electromagnetic valve and the piston is arranged in the other end of the cylinder sleeve. The outer end of the piston corresponds to the inner end of the air exhaust pipe. The outer end of the air exhaust pipe penetrates through the other end of the air storage tank. The circumferential surface of the piston is provided with a sealing ring. The air storage tank is provided with an air inlet connection opening which is connected with a one-way valve on the air inlet direction in series. An air inlet of the electromagnetic valve is connected with one end of a tee. The other two ends of the tee are respectively connected with the other end of the one-way valve and an air source. The utility model has the advantages that a majority of compressed air directly enters a gun body through the air inlet connection opening which is arranged on the air storage tank, the function of the compressed gas entering the electromagnetic valve has the function for pushing the piston to seal the air exhaust pipe, the air through quantity is small, almost no foreign matters are attached to the interior of the electromagnetic valve or on the cylinder sleeve and the normal work is not affected.
Description
Technical field
The utility model relates to a kind of air bubble, specifically is a kind of air bubble and connection structure thereof that is applicable to the shared source of the gas of the material arch camber of eliminating various types of feed bins, hopper, tube furcation place and mine drop shaft, slipping the slope.
Background technology
The structure of traditional air bubble (referring to Fig. 1) comprises storage tank 1, cylinder sleeve 2, piston 3, two-position three way magnetic valve 4 and freeing pipe 5, cylinder sleeve 2 is connected the left end of storage tank 1, the left end of cylinder sleeve 2 connects the outlet of electromagnetic valve 4, the piston 3 of packing in the cylinder sleeve 2, the inner of the corresponding freeing pipe 5 of the right-hand member of piston 3, the right-hand member of freeing pipe 5 passes the right-hand member of storage tank 1, is provided with seal ring 7 at piston 3 side faces.Between the left end of piston 3 and side face, be provided with air extractor vent 8.External air source is connected (the 3rd end of electromagnetic valve 4 communicates with the external world as exhausr port) when using with the admission port of electromagnetic valve 4, external air source is entered the left end of piston 3 by electromagnetic valve 4 controls, the boiler check valve (not shown) that promotes to be located on the piston by the air extractor vent 8 that is located at piston 3 middle parts is opened then, carries out air feed thus.The shortcoming of conventional air big gun and plenum system is:
Whole pressure gass all will enter in the air bubble big gun body by this air feed circuit, greasy dirt impurity in the pressurized air and moisture content are easily attached on the traveller of two-position three way magnetic valve 4 or attached on the cylinder sleeve 2, influence the work of electromagnetic valve 4 and resetting of piston 3, form greasy filth year in and year out, cause electromagnetic valve 4 to damage, or tapping equipment work is malfunctioning, influences the normal use of air bubble.
Summary of the invention
The purpose of this utility model just provides a kind of novel air big gun and connection structure thereof, solving greasy dirt impurity in the source of the gas that prior art exists and moisture content, thereby influence the problem of the normal use of air bubble easily attached in the three-way magnetic valve 4 or attached on the cylinder sleeve and influence the work of electromagnetic valve and resetting of piston.
The technical solution of the utility model is: comprise storage tank, cylinder sleeve, piston, three-way magnetic valve and freeing pipe, cylinder sleeve is connected an end of storage tank, the outer end of cylinder sleeve connects electromagnetic valve, the piston of packing in the other end of cylinder sleeve, the inner of the corresponding freeing pipe in piston outer end, the outer end of freeing pipe passes the other end of storage tank, is provided with seal ring at the piston side face, on described storage tank, be provided with intake interface, on this intake interface, be in series with the one-way cock of airintake direction; The admission port of described electromagnetic valve is connected with an end of a threeway, and the other two ends of this threeway are connected with source of the gas with the other end of described one-way cock respectively.
Plenum system advantage of the present utility model is: the advantage of this air inlet connection structure is that 99.9% pressure gas directly enters the big gun body by the intake interface of opening at storage tank, and the effect of the pressure gas that electromagnetic valve enters just promotes the effect of piston closes freeing pipe, throughput is very little, almost there are not greasy dirt impurity and the moisture content can be attached on the traveller of two-position three way magnetic valve or attached on the cylinder sleeve, can not influence the work of electromagnetic valve and the answer of piston, guarantee the normal lasting work of air bubble.Also saved the air extractor vent on the piston in addition, simplified the structure.
Description of drawings
Fig. 1 is the traditional air bubble and the scheme drawing of air feed connection structure;
Fig. 2 is the scheme drawing of air bubble of the present utility model and air feed connection structure.
The specific embodiment
Referring to Fig. 2, the utility model comprises storage tank 1, cylinder sleeve 2, piston 3, two-position three way magnetic valve 4 and freeing pipe 5, cylinder sleeve 2 is connected the left end of storage tank 1, the left end of cylinder sleeve 2 connects electromagnetic valve 4, the piston 3 of packing in the cylinder sleeve 2, the inner of the corresponding freeing pipe 5 of the right-hand member of piston 3, the right-hand member of freeing pipe 5 passes the right-hand member of storage tank 1, is provided with seal ring 7 at piston 3 side faces.On described storage tank 1, be provided with intake interface 9, on this intake interface, be in series with the one-way cock 10 of airintake direction.The admission port of described three-way magnetic valve 4 is connected with an end of a threeway 12, and the other two ends of this threeway 12 are connected with source of the gas with the arrival end of described one-way cock 10 respectively.Series connected valve 11 on source of the gas.
Working process of the present utility model is: open the valve 11 on the source of the gas, pressurized air enters in the storage tank 1 by check valve 10, when electromagnetic valve 4 is in the state that cylinder sleeve 2 communicates with threeway 12, because piston 3 two ends all are communicated with source of the gas, be in isopiestic state, piston 3 moves right under compressed-air actuated effect and props up the left end of freeing pipe 5, and the pressurized air in jar can not be discharged from freeing pipe 5.When electromagnetic valve dislocation being made cylinder sleeve 2 with extraneous conducting, piston 3 is moved to the left under compressed-air actuated effect, freeing pipe 5 conductings, and pressurized air is emitted from freeing pipe.Two positions of conversion electromagnetic valve 4 can realize blowing out discontinuously continuously.
There is not air extractor vent on the piston 3 of the present utility model, pressurized air enters cylinder sleeve 2 by electromagnetic valve 4 and promotes piston 3 sealing freeing pipes 5, pressurized air only works to promote piston 3 sealing freeing pipes 5 by this path, throughput is very little, has avoided in the source of the gas greasy dirt impurity and moisture content to the influence of electromagnetic valve and piston.The required air of blowing out then is intake interface 9 supplies by newly opening on check valve 10 and the storage tank 1.
