External drain port and spring, the work conversion conductor and circulation leak stopping ontology are connected through a screw thread, and recycle leak stopping ontology side
It is provided with screw connection, the circulation leak stopping body interior is provided with operating mode switching apparatus, including pitching mouth, work
Ball and the outer drain port of bypass, the work ball can be moved forward and backward on piston in cylinder wall, and piston in cylinder wall side is provided with circulation leak stopping
Column is provided with the outer drain port of circulation leak stopping ontology and anti-trochanter on the circulation leak stopping column, and recycles leak stopping column side and set
It is equipped with spring.
Preferably, the work conversion conductor, circulation leak stopping ontology and circulation leak stopping column are equipped with hollow structure.
Compared with prior art, the utility model has the beneficial effects that
Utility model works conversion conductor and circulation leak stopping ontology are connected through a screw thread, it is ensured that upper and lower component can
By connection, and the conversion conductor that works is fastened by bolts, and improves the efficiency of work conversion conductor.Working ball can be in piston cylinder
It is moved forward and backward on wall, when work ball arrives at circulation leak stopping column head, pressure can gradually become larger, at this moment piston motion, band
The dynamic outer drain port of bypass moves down, and pressure drain port can release outside circulation leak stopping ontology.Work conversion conductor, circulation leak stopping sheet
Body and circulation leak stopping column are equipped with hollow structure, can guarantee that leaking for muddy water is smooth in this way, ensure that the work of leak stopping pipe nipple
Make reliability.The outer drain port of circulation leak stopping ontology and anti-trochanter are provided on circulation leak stopping column, the outer drain port of circulation leak stopping ontology can
To guarantee that muddy water normally leaks, anti-trochanter can guarantee to recycle the nonvoluntary sliding of leak stopping column, work more stable, recycle leak stopping
Column lower part is provided with spring, this spring can play adjusting switching pressure value.This circulation leak stopping pipe nipple is reliable with structure, makes
With the good advantage of effect.
