As preferably, also be provided with the groove for self-locking on the described connecting portion, described nylon slide plate is provided with the projection that is complementary with described groove.
As preferably, the spacing head of described front end be conical structure, and the bottom surface diameter of the spacing head of described front end is worn the external diameter of steel pipe more than or equal to need, 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 that need wear 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 the 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 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.
The present invention also provides the using method of above-mentioned pressure vessels for the chemical industry with the compound self-locking target seeker of nylon rubber, it is characterized in that comprising the steps:
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. the pipe end inner wall cleaning is clean, 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 nylon guide leader body in the counterclockwise direction, target seeker rubber sleeve and steel pipe inwall produce radial pressure because of interference fit, the frictional force that target seeker rubber sleeve and steel pipe inwall are asked 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, reaches locking state when the projection of nylon slide plate slips into the groove of connecting portion;
4. after finishing the poling operation of a steel pipe, clockwise direction rotation nylon guide leader body, reach relaxed state until the projection of nylon slide plate and the groove disengaging of nylon guide leader body, 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, finish until whole poling operations.
Compare than prior art, the present invention relies on the big frictional force of target seeker rubber sleeve and steel pipe inwall 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 two wedge shape helical structure of asking expands rubber sleeve gradually, when the projection of nylon slide plate slips into the groove of target seeker body connecting portion, reach locking state, and then the vibration when preventing poling causes that the compound self-locking target seeker of described nylon rubber is loosening.
The present invention has the following advantages:
1, because the present invention 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.
3, if the compound self-locking target seeker of nylon rubber comes off in the poling operation, can be by Electric heating with its fusing and be evaporated to gaseous state and drain.
This present invention can extensively promote in fields such as pressure vessels for the chemical industry poling operations for the foregoing reasons.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Among the figure: 1, nylon guide leader body 11, spacing 12 of front end, stage casing connecting portion 13, connecting portion 131, groove 14, afterbody 2, target seeker rubber sleeve 21, rubber ring 22, nylon slide plate 221, projection
The specific embodiment
As shown in Figure 1, a kind of pressure vessels for the chemical industry comprises nylon guide leader body 1 and target seeker rubber sleeve 2 with the compound self-locking target seeker of nylon rubber; Described target seeker rubber sleeve 2 comprises rubber ring 21 and is fixed on the nylon slide plate 22 (as shown in Figure 2) of at least 1 wedge shape of described rubber ring 21 inside that nylon guide leader body 1 and nylon slide plate 22 all adopt nylon 6 materials, rubber ring 21 employing acrylonitrile-butadiene rubbers.
