Abstract
The invention relates a sealing method for leakage check of a transformer finned radiator, and an inner hook sealer special for the leakage check of the transformer finned radiator, and belongs to the technical field of transformer technological equipment. The technical scheme is that: the inner hook sealer special for the leakage check of the transformer finned radiator comprises a handle piece (1), a rubber ring (2), a pressure rubber steel sleeve (3), a cam handle (4), and a cam rotation shaft (5); the front end of the handle piece is provided with a handle, the rear end has a hook-shaped structure, and a middle part has a cylindrical step-shaped structure in a horizontal direction; the diameter of one end near the handle is small, and the diameter of one end near the hook-shaped structure is large; the inner diameters of the rubber ring and the pressure rubber steel sleeve are smaller than the maximum outer diameter of the step-shaped structure and the rubber ring and the pressure rubber steel sleeve are sleeved on a step in the middle of the handle piece sequentially; the cam rotation shaft is arranged on the handle piece and near the pressure rubber steel sleeve; and the cam rotation shaft is provided with the cam handle. The inner hook sealer is not operated outside a steel pipe for sealing but is operated inside the steel pipe for sealing; and the sealer mechanically hooks a hole on the inner part, so tensile and shear strength is large, and the sealer is absolutely safe and reliable when high air pressure is applied to the sealer.
Description
Technical field
The present invention relates to collude sealer in encapsulating method that a kind of transformer chip radiator leak test uses and the special use, be used for the steel tube head sealing, airtightly in the leak test operation do not seep water, belong to transformer Equipment Technology field.
Background technique
The leak test operation needs steel tube head sealing in the transformer chip radiator manufacture process, airtightly in the leak test operation does not seep water.At present, the conventional seals device of can't blue matrix formula radiator leak test using is to clamp outer diameter of steel pipes with bolt arrangement, and rubber cushion and cover plate are installed again.The problem that exists is: action link is many during installation, and sealer is from great, and it is slow to adorn, tear open speed, adorns, tears open once about 4 minutes.Because the conventional seals device is to embrace in the conduct of outer diameter of steel pipes frictionally to fix, and receives in the situation of highpressure pressure, sealer has the possibility that is ejected.
Summary of the invention
The purpose of this invention is to provide in encapsulating method that a kind of transformer chip radiator leak test uses and the special use and collude sealer, efficient is high, adorns, tears open once several approximately seconds; Volume, weight are little; The tension shearing strength is big, and is safe and reliable, solves the problems referred to above that background technique exists.
Technological scheme of the present invention: transformer chip radiator leak test colludes sealer in using, and comprises handgrip spare, rubber ring, moulding steel bushing, cam handle, cam shaft, and handgrip spare front end is a handle; The rear end is a hook arrangement, and the by-level direction is the cylinder step-like structure, and is less near an end diameter of handle; End diameter near hook arrangement is bigger; The internal diameter of rubber ring and moulding steel bushing is sleeved on the middle step of handgrip spare less than the maximum outside diameter of step-like structure successively, and cam shaft is arranged on the handgrip spare; Near the moulding steel bushing, cam handle is set on the cam shaft.
The moulding steel bushing can slide.
Because be provided with the hole in the steel pipe that needs to seal, the present invention utilizes the existing hole of steel pipe, with the hook arrangement of handgrip spare front end, catch on the hole from the steel pipe the inside, seal, so collude sealer in being called.
The encapsulating method that transformer chip radiator leak test is used; Use in the special use and collude sealer, comprise following steps: 1. utilize the existing hole of leak test steel tube head, the lining is colluded sealer and is filled in steel pipe with lateral attitude; With the hook arrangement of handgrip spare front end, catch on the hole from the steel pipe the inside; 2. press down cam handle, drive cam rotation, cam extruding, promotion moulding steel bushing, the moulding steel bushing can slide, and the moulding steel bushing is stressed to be moved inwards, makes and is pressed the tight steel pipe inwall of rubber central shoring, accomplishes sealing.
The moulding steel bushing is enclosed within on the handgrip spare, can horizontally slip.The moulding steel bushing is oppressed rubber ring after being oppressed by cam then, makes rubber deformation, and rubber is tight with the support of steel pipe inwall.
Good effect of the present invention: the present invention does not accomplish sealing in the steel pipe peripheral operation, carries out portion's operation in steel duct and accomplishes sealing; Compare with the conventional general sealer, tens times of high working efficiency, small and exquisite safe and reliable, adopt cam handle, will locate, seal a step and accomplish.The present invention has following advantage: efficient is high, adorns, tears open once several approximately seconds; Volume, weight ratio conventional seals device are half as large; Because mechanical hole of catching on the inside, so the tension shearing strength is very big, it is reliable also to be perfectly safe when receiving highpressure pressure.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further specified through embodiment.
Transformer chip radiator leak test use in collude sealer, comprise handgrip spare 1, rubber ring 2, moulding steel bushing 3, cam handle 4, cam shaft 5, handgrip spare front end is a handle; The rear end is a hook arrangement, and the by-level direction is the cylinder step-like structure, and is less near an end diameter of handle; End diameter near hook arrangement is bigger; The internal diameter of rubber ring and moulding steel bushing is sleeved on the middle step of handgrip spare less than the maximum outside diameter of step-like structure successively, and cam shaft is arranged on the handgrip spare; Near the moulding steel bushing, cam handle is set on the cam shaft.The moulding steel bushing can slide.Because be provided with the hole in the steel pipe that needs to seal, the present invention utilizes the existing hole of steel pipe, with the hook arrangement of handgrip spare front end, catch on the hole from the steel pipe the inside, seal, so collude sealer in being called.
The encapsulating method that transformer chip radiator leak test is used; Use in the special use and collude sealer, comprise following steps: 1. utilize the existing hole of leak test steel tube head, the lining is colluded sealer and is filled in steel pipe with lateral attitude; With the hook arrangement of handgrip spare front end, catch on the hole from the steel pipe the inside; 2. press down cam handle, drive cam rotation, cam extruding, promotion moulding steel bushing, the moulding steel bushing can slide, and the moulding steel bushing is stressed to be moved inwards, makes and is pressed the tight steel pipe inwall of rubber central shoring, accomplishes sealing.
