The destruction of valve borehole wall sealing effect is caused, while also can not be to carrying out protection against water penetration in valve well.
Summary of the invention
In view of this, the utility model, which is directed to a kind of flexible sealing, crosses wall coil part, it is used cooperatively fixes sleeve, outer shield
Pipe, flexible graphite stuffing, telescopic joint and fastening snap ring；Flexible sealing may be implemented and cross wall effect, have sealing effect good, it is fixed
Stablize and adapt to the characteristics of tubing moves radially.
In order to achieve the above objectives, the technical solution of the utility model is achieved in that
A kind of flexible sealing crosses wall coil part, including working steel tube；Working steel tube housing outer protection tube, outer protection tube housing fixing sleeve
Cylinder is equipped with flexible graphite stuffing between fixes sleeve and outer protection tube；Flexible graphite stuffing is wound along the edge of fixes sleeve；It is fixed
Sleeve outer wall is equipped with fixed disk, and fixed disk is arranged in the valve borehole wall；Fixes sleeve one end passes through telescopic joint and fastening snap ring
Connection, fastening snap ring are fixed in outer protection tube.
In the practical application of the utility model, the soft good and intensity of flexible graphite stuffing is high, adsorbable to enter in well room
Moisture, have good sealing performance, effectively prevent fastening snap ring corrosion.Fixes sleeve one end passes through telescopic joint and fastening
Snap ring connection, is adapted to moving radially for outer protection tube generation.
Further, fixed disk is separated with working steel tube and is fixedly connected.
When progress flexible sealing crosses the installation of wall coil part, the connection between dismountable fixed disk and working steel tube is pre-fixed.
Further, fixed disk is arranged in the middle part of fixes sleeve outer wall.
Further, telescopic joint is arranged on the inside of the valve borehole wall.
Further, fixed disk is connect by bolt with working steel tube.
Further, telescopic joint is externally provided with shell.
Compared with the existing technology, a kind of flexible sealing of the utility model crosses wall coil part, has the advantage that
A kind of flexible sealing of the utility model crosses wall coil part, with the use of fixes sleeve, outer protection tube, flexible graphite stuffing,
Telescopic joint and fastening snap ring；Flexible sealing may be implemented and cross wall effect, have sealing effect good, fixing-stable and adaptation tubing
The characteristics of moving radially.
