As preferably, described connecting portion is also provided with the groove for self-locking, described nylon slide plate is provided with the projection with described groove match.
As preferably, the spacing head in described front end is conical structure, and the basal diameter of the spacing head in described front end is more than or equal to the external diameter need wearing steel pipe, and the external diameter of the rubber ring of described target seeker rubber sleeve equals 1.05 ~ 1.1D, and wherein, D is the internal diameter need wearing steel pipe.
As preferably, the material of described nylon guide leader body and described nylon slide plate is nylon 6.
As preferably, the material of described rubber ring is the acrylonitrile-butadiene rubber of hardness in oil resistant low temperature resistant.
The stage casing connecting portion of target seeker body provided by the invention is cylindrical structure, and the spacing head of its front end adopts conical structure, and when the stage casing connecting portion of nylon guide leader body penetrates in steel pipe, the spacing head in front end plays position-limiting action; The size of the tapered helical structure of the connecting portion of target seeker body and the size of nylon slide plate match, and can reach the effect fitted tightly, the groove of setting and projection play self-locking effect.
Present invention also offers the using method of above-mentioned pressure vessels for the chemical industry nylon rubber compound self-locking target seeker, it is characterized in that comprising the steps:
1. body of being taken the lead by nylon guide penetrates in target seeker rubber sleeve, and the tapered helical structure of connecting portion of adjustment nylon guide leader body is agreed with mutually with the nylon slide plate in target seeker rubber sleeve;
2. inner wall of steel tube end is cleaned out, the nylon guide leader body being equipped with target seeker rubber sleeve is penetrated in steel pipe;
3. after target seeker rubber sleeve length direction all enters steel pipe, rotate nylon guide leader body in the counterclockwise direction, target seeker rubber sleeve and steel pipe inner wall produce radial pressure because of interference fit, frictional force between target seeker rubber sleeve and steel pipe inner wall is greater than the frictional force that in target seeker rubber sleeve, nylon slide plate and nylon guide are taken the lead between body connecting portion, when nylon guide leader body rotates, target seeker rubber sleeve does not rotate, nylon guide leader body slides along nylon slide plate, rubber ring expands gradually, until reach locking state when the projection of nylon slide plate slips into the groove of connecting portion,
4. after completing the poling operation of a steel pipe, rotate nylon guide leader body clockwise, until the projection of nylon slide plate and nylon guide are taken the lead, the groove of body departs from and reaches relaxed state, extract nylon guide leader body and target seeker rubber sleeve repeat above-mentioned steps, carry out the poling operation of next root steel pipe, until all poling operation completes.
Comparatively prior art is compared, the present invention relies on the larger frictional force of target seeker rubber sleeve and steel pipe inner wall that nylon slide plate is fixed relative to target seeker body, target seeker body slides along the nylon slide plate in target seeker rubber sleeve, tapered helical structure between the two makes rubber sleeve expand gradually, until reach locking state when the projection of nylon slide plate slips into the groove of target seeker body connecting portion, and then prevent vibration during poling from causing described nylon rubber compound self-locking target seeker to loosen.
The present invention has the following advantages:
1, due to the present invention's employing is nylon rubber compound self-locking structure, improves the stability of target seeker in steel pipe, difficult drop-off, is convenient to poling operation.
2, nylon rubber compound self-locking target seeker structure is simple, easy to operate.
If 3 nylon rubber compound self-locking target seekers come off in poling operation, melted by Electric heating and be evaporated to gaseous state and drained.
This present invention extensively can promote in fields such as pressure vessels for the chemical industry poling operations for the foregoing reasons.
