Summary of the invention
The technical problem of the actual solution of the utility model is: assemble very complicated, change the O RunddichtringO inconvenient, and each cylinder cap segment concentricity requirement is high, difficulty of processing is high, in case assembling screw discontinuity, concentricity is difficult to guarantee, thereby affect the working life of seal degree and whole device, if the tension that screw is twisted can cause the O RunddichtringO to damage, so the O RunddichtringO is changed very frequent.
The utility model provides the sealing configuration of a kind of reciprocating type applying glue pump piston and cylinder cap, comprise piston rod 1, glue pump cylinder cap group, center hole and described glue pump cylinder cap group that described piston rod penetrates described glue pump cylinder cap group are slidingly matched, it is characterized in that: described glue pump cylinder cap group comprises cylinder cap seat 3 and cylinder cap 2, described cylinder cap 2 has outside thread, described cylinder cap seat 3 contains two sections cascade grooves, in the first paragraph groove of described cylinder cap seat 3 internal thread is arranged, be threaded in the first paragraph groove of the described cylinder cap seat 3 of described cylinder cap 2 embeddings and with described cylinder cap seat, one group of V-shaped seal ring is set in the second segment groove of described cylinder cap seat 3, and described applying glue sucker rod 1 seals by described V-shaped seal ring with the cylinder cap group.
Described cylinder cap seat 3 is at least 3 through holes of uniform setting 5 vertically, and described cylinder cap seat 3 can be connected with the glue pump housing 9 by described through hole 5.
Described cylinder cap 2 outside end faces are uniform vertically to arrange one group for using spanner to regulate the auxiliary hole 12 that described cylinder cap 2 cylinder cap seats 3 are threaded.
Also have one or more little grooves on the described cylinder cap 2 center hole hole walls, a new O RunddichtringO 7 is set respectively in the described little groove.
Described V-shaped seal ring is that described V-shaped seal ring is that five layers in tetrafluoroethylene can be regulated the combination V-shaped seal ring.
The beneficial effects of the utility model are: a kind of easy processing is provided, and assembling is simple, and tightness is high, piston rod is subjected to extent of corrosion little, the seal ring long service life does not need the frequent seal ring, and concentricity is held the sealing configuration of manageable reciprocating type applying glue pump piston and cylinder cap.Simultaneously, manufacturing efficiency improves 15%, reduces 300 of product rejections every day, saves 3 barrels of glue wastes/per month, save and safeguard artificial 2 people, has reduced pollution and the waste of glue to environment, reduce piston rod consume 4 covers/month.
