It is equal.
The depth of the annular groove I and annular groove II is the 1/4 of cock body depth；The width of the annular groove I is
The 1/5 of umbrella chock plug and cock body total height.
The thermoplastic elastomer (TPE) TPV is by with brominated isobutylene-p-methylstyrene copolymer and polyolefin elastomer
Carry out what dynamic vulcanization was made.
The piston inner diameter is 60-70% with the ratio of external diameter.
The beneficial effects of the utility model are：
（1）Production Large Copacity clamped bottle thermoplastic elastomer (TPE) piston, selects brominated isobutylene p-methylstyrene copolymerization
Thing is base rubber, and the polyolefin elastomer of cleaning uses technique, prepares thermoplastic elastomer (TPE) TPV.It is fully saturated
Polymer, purity is high in itself for material, and extractable and extract are few；Its heat resistance and ozone resistance are also greatly improved, resistance to ray
Radianting capacity is strong；
（2）Thermoplastic elastomer (TPE) TPV used have elastic good, moderate strength, easily shaping, product's dimensional precision compared with
Height, in actual use, is unlikely to deform, and piston face is provided with sealing ring, with excellent sealing and sliding, produces
The advantages of product flexible design, resistance to various sterilizing requirements, environmentally friendly recoverable；
（3）Can be processed on conventional injection molding apparatus, one-shot forming is settled at one go, and processing step is few, production link
Simply, production efficiency is high, and product cleanliness factor is higher.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
