Abstract
The invention relates to an automatic compensatory double-lip soft piston. The automatic compensatory double-lip soft piston comprises a front press plate, a chrysanthemum-shaped elastic piece, a front modified polytetrafluoroethylene leather cup, a rear modified polytetrafluoroethylene leather cup and a rear press plate, wherein the chrysanthemum-shaped elastic piece is connected between the front press plate and the front modified polytetrafluoroethylene leather cup, the front modified polytetrafluoroethylene leather cup is connected with the rear modified polytetrafluoroethylene leather cup, and the rear modified polytetrafluoroethylene leather cup is connected with the rear press plate. The automatic compensatory double-lip soft piston is safe in use, is environment-friendly and can discharge sundries in time, compensate a lip to a cylinder body in time, increase compactness and decrease leakage.
Description
Technical field
The invention relates to soft piston field, specifically about the soft piston of a kind of lips auto-compensation.
Background technique
Plug is widely used in automobile industry, and is the core apparatus of motor car engine.But along with the development of present advanced technology, the variation of component device, soft piston also extensive use gets up, play a good role in oiling machine flow meter, soft piston is because be soft material, reduce the hard grind with weighing machine in oilling machine, wear resistance and sealing make soft piston obtain extensive concern.But the soft piston of present major part, can not auto-compensation, the tiny grains of sand in oil product can not be got rid of in time, and lip quantity is few, and lip does not compensate shell fragment, time can follow the string under growing rear and low temperature, cause leakage, poor sealing, cause metering inaccurate, thus cause economic loss, also waste the energy.
As can be seen here, above-mentioned existing soft piston with in use in structure, obviously still has inconvenience and defect, and is urgently further improved.In order to solve above-mentioned Problems existing, relevant manufactures there's no one who doesn't or isn't seeks solution painstakingly, but have no applicable design for a long time to be completed by development, and common product does not have appropriate structure to solve the problem, this is obviously the anxious problem for solving of relevant dealer always.
Summary of the invention
The object of the present invention is to provide the soft piston of a kind of lips auto-compensation, technical problem to be solved is, soft piston easily follows the string after a long time use with under low temperature, cause leakage, poor sealing, cause metering inaccurate, thus cause economic loss, also waste energy.
The object of the invention is to realize by the following technical solutions.The present invention proposes the soft piston of a kind of lips auto-compensation, it is characterized in that comprising: leather cup and rear platen after leather cup, modified Teflon before front platen, chrysanthemum shell fragment, modified Teflon, wherein said chrysanthemum shell fragment to be connected to before described front platen and modified Teflon between leather cup, before described modified Teflon, leather cup is connected with leather cup after modified Teflon, and after modified Teflon, leather cup is connected with rear platen.
By technique scheme, the soft piston of lips auto-compensation of the present invention at least has following advantages and beneficial effect: structure of the present invention is simple, and use safety environmental protection, can get rid of foreign material in time, there is lip and include chrysanthemum shell fragment, lip can be compensated in time to cylinder body, increase compactness, reduce and reveal, thus guarantee that oiling machine flow meter measuring accuracy is accurate, saved cost, reducing the energy and run off, is the product that can be used widely.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to technological means of the present invention can be better understood, and can be implemented according to the content of specification, and can become apparent to allow above and other object of the present invention, feature and advantage, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the structural representation of the soft piston of lips auto-compensation of the present invention.
[primary component symbol description]
1: front platen 2: chrysanthemum shell fragment
3: front leather cup 4: rear leather cup
5: rear platen
Embodiment
For further setting forth the present invention for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to the embodiment of the soft piston of a kind of lips auto-compensation proposed according to the present invention, structure, feature and effect thereof, be described in detail as follows.
Referring to Fig. 1, is the structural representation of the soft piston of lips auto-compensation of the present invention.It comprises: leather cup 4, rear platen 5 after front platen 1, chrysanthemum shell fragment 2, the front leather cup of modified Teflon 3, modified Teflon.Wherein, chrysanthemum shell fragment 2 is connected to before front platen 1 and modified Teflon between leather cup 3, and before modified Teflon, leather cup 3 is connected with leather cup after modified Teflon 4, and after modified Teflon, leather cup 4 is connected with rear platen 5.Chrysanthemum shell fragment 2 compensates the lip of leather cup in time, makes leather cup lip be close to casing wall, guarantees the sealing of piston and cylinder sleeve, avoids revealing, reduces the loss of the energy.By front and back platen 1,5, leather cup before and after modified Teflon 3,4 and chrysanthemum shell fragment 2 are firmly coupled together, play two way sealed effect, wear-resisting and anti-corrosion capability is strong, increases the working life of piston.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
Claims (1)
1. the soft piston of lips auto-compensation, it is characterized in that comprising: leather cup and rear platen after leather cup, modified Teflon before front platen, chrysanthemum shell fragment, modified Teflon, wherein said chrysanthemum shell fragment to be connected to before described front platen and modified Teflon between leather cup, before described modified Teflon, leather cup is connected with leather cup after modified Teflon, and after modified Teflon, leather cup is connected with rear platen.
