Description
Technical field
The utility model belongs to air bubble field, is specifically related to a kind of air artillery piston.
Background technology
Air bubble is applied very extensive in the industry, and as a kind of dredging device, when occurring feed blocking, it can send high velocity air, thus makes the flowing of material recover smooth and easy, ensure that industrially normally to carry out.
As the important component part of air bubble, the work efficiency of piston to whole air bubble serves vital effect.Along with the crank motion of piston, air bubble can be jetted high velocity air.
The leak tightness of piston and the work efficiency of resistance to effect of heat on piston have direct impact, the piston used in prior art is made for plastics, its temperature capacity is poor, often there is wear problem in end, and easily under the working environment of high temperature, there is problem on deformation, cause cisco unity malfunction, the life-span is lower.
Utility model content
It is simple that the utility model aims to provide a kind of structure, the air artillery piston that result of use is good.
For solving above technical matters, the utility model provides following technical scheme: a kind of air artillery piston, comprise piston body, piston body side is arranged two seal grooves, seal ring is provided with in seal groove, innovation of the present utility model is: piston body front portion is provided with cavity, piston body comprises leading section and rearward end, leading section connects piston rod, rearward end is provided with the pressing plate be fixedly connected with rearward end, between pressing plate and rearward end, be provided with Rubber Parts, Rubber Parts is arranged at the circular trough be positioned in rearward end.
Rubber Parts is provided with pressing plate groove, pressing plate is positioned at pressing plate groove, the outside face of pressing plate and the flush with outer surface of Rubber Parts.
Pressing plate is fixedly connected with piston body by bolt, and bolt is arranged on pressing plate and Rubber Parts, and one end is stretched in piston body, and is fixed by the nut being positioned at piston body, and the other end is fixed by the nut be positioned at outside rearward end.
Described seal ring material is rubber.
Described piston body material is aluminium.
By above technical scheme, the beneficial effects of the utility model are: the Rubber Parts that 1, piston body rearward end is arranged improves the resistance to effect of heat of piston, can tolerate the high temperature of 300-400 DEG C, effectively prevent the distortion of piston, prevent piston body end to be damaged simultaneously, extend service life; 2, two seal rings that the side of piston body is arranged ensure that sealing, improve the work efficiency of piston; Rubber Parts, by being positioned at the cavities seals of piston body front end, is fixed in the rearward end of piston body by the pressing plate 3, be connected with piston body by bolt simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model semisectional view;
Fig. 2 is the upward view of Fig. 1.
Detailed description of the invention
Air artillery piston as shown in Figures 1 and 2, comprise piston body 1, piston body 1 adopts aluminum material, the side of piston body 1 is provided with two seal grooves, seal ring 4 is provided with in two seal grooves, seal ring material is rubber, thus piston is played to the effect of sealing, improves the result of use of piston.Piston body 1 comprises leading section 2 and rearward end 3, leading section 2 is for being connected with piston rod, the cavity 6 connected for piston rod is set in the front end of piston body 1, thus piston body 1 is moved reciprocatingly under the drive of piston rod, rearward end 3 is provided with circular trough, Rubber Parts 33 is provided with in circular trough, Rubber Parts 33 is provided with pressing plate groove, pressing plate 32 is provided with in pressing plate groove, pressing plate 32 and Rubber Parts 33 are fixedly connected with by bolt 5 with rearward end 3, bolt 5 is arranged on pressing plate 32 and Rubber Parts 33, one end is stretched in piston body 1, and fixed by the nut 31 being positioned at piston body 1, nut 31 in piston body 1 is positioned at cavity 6, bolt 5 other end is fixed by the nut 31 be positioned at outside pressing plate 32, thus pressing plate 32 is fixed on piston body 1, being fixedly connected with of Rubber Parts 33 and piston body 1 is achieved by bolt 5 and pressing plate 32, Rubber Parts 33 material is rubber, the outside face of pressing plate 32 and the outside face of Rubber Parts 33 are positioned on the same face, the pressing plate 32 arranged and Rubber Parts 33 can improve piston resistance to effect of heat in use, effectively prevent piston distortion in use, extend the service life of equipment.The piston body 1 of hollow seals by the pressing plate 32 arranged, and is fixedly connected with by Rubber Parts 33 by pressing plate 32 with rearward end 3.
In the process of pistons work, have the generation of heat, Rubber Parts 33 prevents piston body 1 end to receive damage, improve resistance to heat simultaneously, the high temperature of 300-400 DEG C can be born, effectively prevent the distortion of piston body 1, improve the service life of equipment simultaneously.
The utility model structure is simple, in the process used, piston body 1 moves reciprocatingly under the drive of the piston rod be connected with leading section 2, in the process advanced, gas is jetted from air bubble, thus generation high velocity air, in the process of returning, inside is made to enter gas, so that carry out progradation next time, two seal rings being wherein arranged at piston body 1 side can be tightly connected with piston barrel, prevent in the process advanced, gas from both junction out, reduce the result of use of piston, the Rubber Parts that piston body 1 rearward end is arranged and pressing plate improve the resistance to heat of piston, effectively prevent the distortion of piston in thermal histories, piston body end is prevented to receive damage, extend the service life of piston.
