The stage casing connecting portion of the target seeker body that the utility model provides 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 penetrated in the steel pipe, the spacing head of front end played position-limiting action; The size of the wedge shape helical structure of the connecting portion of target seeker body and the size of nylon slide plate are complementary, and can reach the effect that fits tightly, and the groove of setting and projection play the self-locking effect.
Above-mentioned pressure vessels for the chemical industry comprises the steps: with the compound self-locking target seeker of nylon rubber in use
1. the body of nylon guide being taken the lead penetrates in the target seeker rubber sleeve, and the wedge shape helical structure of the connecting portion of adjustment nylon guide leader body agrees with mutually with the nylon slide plate in the target seeker rubber sleeve;
2. inner wall of steel tube end is cleaned out, the nylon guide leader body that is equipped with the target seeker rubber sleeve is penetrated in the steel pipe;
3. after target seeker rubber sleeve length direction all enters steel pipe, rotate in the counterclockwise direction nylon guide leader body, 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 between nylon slide plate and nylon guide leader body connecting portion in the target seeker rubber sleeve, when nylon guide leader body rotates, the target seeker rubber sleeve does not rotate, nylon guide leader body slides along the nylon slide plate, rubber ring expands gradually, until the projection of nylon slide plate reaches locking state when slipping into the groove of connecting portion;
4. after finishing the poling operation of a steel pipe, rotate clockwise nylon guide leader body, until breaking away from, the groove of the projection of nylon slide plate and nylon guide leader body reaches relaxed state, extract nylon guide leader body and target seeker rubber sleeve and repeat above-mentioned steps, carry out the poling operation of next root steel pipe, until all the poling operation is finished.
Compare than prior art, the utility model relies on the larger frictional force of target seeker rubber sleeve and steel pipe inner wall that the nylon slide plate is fixed with respect to the target seeker body, the target seeker body slides along the nylon slide plate in the target seeker rubber sleeve, the wedge shape helical structure of the two expands rubber sleeve gradually, until the projection of nylon slide plate reaches locking state when slipping into the groove of target seeker body connecting portion, and then the vibration when preventing poling causes that the compound self-locking target seeker of described nylon rubber is loosening.
The utlity model has following advantage:
1, because the utility model adopts is the compound self-locking structure of nylon rubber, improved the stability of target seeker in steel pipe, difficult drop-off is convenient to the poling operation.
2, the compound self-locking target seeker of nylon rubber is simple in structure, easy to operate.
If the compound self-locking target seeker of 3 nylon rubbers comes off in the poling operation, can be by Electric heating with its fusing and be evaporated to gaseous state and drain.
This utility model can extensively be promoted in fields such as pressure vessels for the chemical industry poling operations for the foregoing reasons.
