Abstract
The utility model relates to the technical field of oil-free lubrication piston rings of a piston compressor, in particular to a halved gap piston ring. The halved gap piston ring consists of two halved piston ring bodies that are detachably connected together to form a complete piston ring. Compared with the prior art, the halved gap piston ring is novel and simple in structure, and quite convenient in installation process, greatly improves sealing performance, avoids consideration of deformation problem and ensures sealing effect with low wear rate, thus effectively prolonging the use period of the piston ring in a high pressure air cylinder. Besides, the halved gap piston ring is easy to manufacture, low in cost and worthy of promotion and application.
Description
[technical field]
The utility model relates to piston compressor oil-free lubrication piston ring technical field, specifically a kind of gap piston ring of half-and-half taking.
[background technique]
At present, existing piston formula compressor oil-free lubrication piston ring is overall structure, is difficult to solve this technical problem of piston ring radial thickness.If radial thickness is too thin, then be easy to wearing and tearing, the sealing effect extreme difference; And the radial thickness thickening then has to be difficult to install.In addition, the existing piston ring is easy to out think problem on deformation in installation process, and it is in operation leakage phenomenon very easily occurs, has shortened the working life of piston ring greatly.
The high pressure cylinder oil-free lubrication piston ring that with the cylinder bore is Ф 150 is an example, if radial thickness is got 6 millimeters, then the pot type piston ring made of metallo-plastic is difficult to resist powerful back pressure suffered in cylinder operation, is wear out failure in the short time.If ring radial thickness is thickeied to 8 millimeters, then piston ring is difficult to break into two with one's hands and is installed in the piston.Break the circularity that can destroy piston ring by force into two with one's hands and make it the sealability variation, wear rate strengthens, and using effect is poor, and the operation cycle is short.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of gap piston ring of half-and-half taking is provided, adopt the metallo-plastic piston ring of double fibulae type structure, solved the installation difficult problem of the bigger ring of radial thickness well, both reduced leakage, solved the problem in working life of piston ring again, for applying of oil-free lubrication technology played crucial effect.
Design a kind of gap piston ring of half-and-half taking for achieving the above object, described piston ring is made up of two double piston ring ring bodies, adopts detachable connection between described two double piston ring ring bodies, constitutes a complete piston ring.
The both ends open place of described double piston ring ring body is provided with the overlap joint mouth that cooperatively interacts with another double piston ring ring body both ends open, adopts fibulae type to connect between described two double piston ring ring bodies.
Described double piston ring ring body adopts plastimets to make.
The utility model is compared with prior art, novel structure, simple has improved the performance that seals greatly, and installation process is very convenient, and need not to consider problem on deformation, sealing effect is guaranteed, and wear rate is low, thereby has prolonged the life cycle of piston ring in high pressure cylinder effectively, in addition, the utility model is made simple, and cost is low, is worthy of popularization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional drawing of Fig. 1;
Among the figure: 1 is that double piston ring ring body, 2 is overlap joint mouthful.
[embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in drawings, piston ring of the present utility model is made up of two double piston ring ring bodies 1, adopts detachable connection between described two double piston ring ring bodies, constitutes a complete piston ring.Specifically the both ends open place of double piston ring ring body is provided with the overlap joint mouth 2 that cooperatively interacts with another double piston ring ring body both ends open, adopts fibulae type to connect between described two double piston ring ring bodies.Described double piston ring ring body adopts plastimets to make.Both solve the problem on deformation of plastimets in installation, reduced its leakage problem that is in operation again, prolonged the working life of piston ring effectively.
