The utility model discloses compact structure presss from both sides tightly reliably, and the clamp force is big, and the leakproofness is good, convenient to use, and the clamp is tight quick, the rapid operation, the security is strong, the production efficiency height. But the wide application is in heat exchange tube leak test, pressure testing system.
Description
Technical field
The present invention relates to a kind of embracing and press from both sides internal enclosed quick chuck, can be widely applied in heat exchanger tube leak test, pressure testing system.
Background technology
Existing chuck, switching performance and sealing are poor, in use, because of insufficient clamping force, often connect and are prone to disengage, and safety is also poor, directly affects certainty of measurement.
Summary of the invention
It is an object of the invention to provide that a kind of compact conformation, reliable clamping, clamping force be big, good airproof performance, easy to use, clamping quickly, rapid operation, high safety, production efficiency high embrace folder internal enclosed quick chuck.
In order to achieve the above object, the present invention embraces folder internal enclosed quick chuck, including with the hollow adapter of step of externally threaded end, by the holding nut that threaded engagement adapter hollow with end step is connected, against holding nut end, matched in clearance is arranged in the hollow adapter of end step and at both ends with the cushion block of cambered surface projection, the eccentric handle on cushion block it is arranged on by bearing pin, against cushion block end, matched in clearance is arranged on the locking bed in the hollow adapter of end step, the back-up ring in the hollow adapter of end step and sealing ring it is sequentially arranged between the step of locking bed and the hollow adapter of end step, the tapered sleeve plug screw on locking bed it is connected to by threaded engagement, it is arranged on the sliding sleeve in tapered sleeve plug screw endoporus and locking tapered sleeve.
The present invention embraces folder internal enclosed quick chuck, and described locking tapered sleeve, its endoporus is with profile of tooth, and is longitudinally divided into some points of lobes.
The present invention embraces folder internal enclosed quick chuck, and its operation principle is: tested heat exchanger tube is inserted chuck, and toward being tightened against in locking bed, direction screws tapered sleeve plug screw, promote locking tapered sleeve, hold tightly and firmly clamp heat exchanger tube, then pulling eccentric handle, by cushion block, holding nut, pull out hollow adapter, compresses seal, so as to expand, it is adjacent to heat exchanger tube inwall, exchange heat pipe reliably seals, and produces frictional resistance, overcomes testing high voltage liquid to the outside thrust of chuck.
The present invention embraces folder internal enclosed quick chuck, described locking tapered sleeve, and its endoporus, with saw-tooth thread, is to improve frictional force, increases the occlusion ability of exchange heat pipe, it is prevented that heat exchanger tube comes off, and further enhances the reliability of clamping, and clamping force is big.
The present invention embraces folder internal enclosed quick chuck, and compact conformation, clamping easy to use is quick.
The present invention embraces folder internal enclosed quick chuck, described sealing ring, adopts hollow cylinder polyurethane sealing ring, and elastic stiffness is little, and resistance of deformation is low, rapid operation, good airproof performance.
The present invention embraces folder internal enclosed quick chuck, and heat exchanger tube is outside embraces clamping structure, adopts the locking tapered sleeve dividing lobe combine with tooth, has and embraces that folder is reliable, get loose feature thoroughly, it is simple to installs, dismantles.
The present invention embraces folder internal enclosed quick chuck, is that the chucking power of locking tapered sleeve generation in the outer part acts on the tensile force of pipe inner seal circle generation simultaneously, produces two groups of stiction with the inside and outside wall of heat exchanger tube, be firmly connected with tested steel pipe.Being computed and experiment test, namely the frictional force of any one group can be substantially larger than testing high voltage liquid to the outside thrust of chuck, it is ensured that the reliability that chuck connects, and substantially increases the safety of detection process.
The present invention embraces folder internal enclosed quick chuck, easy and simple to handle, quick, meets pressuring pump and the requirement of heat exchanger tube rapid-assembling/disassembling in production, significantly improves production efficiency.
In sum, the present invention embraces folder internal enclosed quick chuck, compact conformation, reliable clamping, and clamping force is big, and good airproof performance is easy to use, and quickly, rapid operation, high safety, production efficiency is high in clamping.
