Background technique
At present, known butter machine mostly is the to-and-fro motion drive material lifting mechanism raising oil pressure through pneumatic element, and through grease gun the parts that need oiling is carried out oiling; But the spool of existing material lifting mechanism causes poor sealing because its structural design is reasonable inadequately; Oil leakage phenomenon is serious, and working life is not high, brings the efficient of Lubricators low thus; The frequency of dismounting maintenance is high, and labor intensity is big, and cost of production is high.
Summary of the invention
The purpose of the utility model provides the spool of the pneumatic high-voltage oil gun of a kind of good seal, long service life, high working efficiency.
The purpose of the utility model is achieved in that
The spool of pneumatic high-voltage oil gun; The front portion of the leading portion of hollow spool housing is provided with and is provided with circular groove between two parties with externally threaded joint, rear portion and makes the tail side at rear portion form an assembly department; In the spool housing, back segment is disposed with the two-stage cylindrical body step that external diameter strengthens successively; The middle part and the afterbody of stage casing step are arranged at intervals with annular boss; The bi-side that back segment step afterbody is relative are provided with truncation portion, middle part and are provided with through axis and perpendicular to the large through-hole on the plane of truncation portion, and truncation portion is provided with through axis and is parallel to the small through hole of truncation portion, and the assembly department of spool housing is provided with annular gasket; Be provided with seal ring between two annular boss, be provided with seal ring between the annular boss of annular gasket and front side.
The seal ring that is provided with between above-mentioned two annular boss is the O RunddichtringO.
Above-mentioned O RunddichtringO is processed with rubber material.
The cross section of the seal ring that is provided with between the annular boss of above-mentioned annular gasket and front side is a rectangle.
Above-mentioned rectangular seal is processed with polytetrafluoroethylmaterial material.
The leading portion end face of above-mentioned spool housing and the junction of center hole are provided with chamfering.
The utility model is compared the outstanding and beneficial technical effects of existing technology:
1, the O RunddichtringO of the utility model with rubber material process, rectangular seal processes with polytetrafluoroethylmaterial material, particularly the wear resistance of teflin ring is good, therefore makes that the whole service life of product is long.
2, the utility model adopts the two seals circle, and the wear resistance of seal ring is good in addition, makes the good airproof performance of product, and leakage of oil is few, and oiling efficient is high.
3, therefore the long service life of the utility model has reduced dismounting frequency of maintenance and maintenance expenses, has reduced labor intensity, the spool of the pneumatic high-voltage oil gun of work.
4, the utility model is simple in structure, is applicable to the spool of making various pneumatic high-voltage oil guns.
