Abstract
The utility model discloses an easy dismouting hydraulic tensioning ware of pressure release, the elongator is including tensile main part, nut cover, swivel nut, second section is provided with the nut cover in the tensile main part, first section is provided with the swivel nut in the tensile main part, the oil inlet has been seted up to tensile main part lateral wall, pressure releasing pathway has been seted up on the swivel nut, pressure releasing pathway and oil inlet communicate with each other, pressure releasing pathway and pressure release mouth are connected, pressure release mouth and swivel nut are connected through sealed plug screw. The utility model has the advantages that: it is rational in infrastructure, easily make, the practicality is strong, and pressure releasing pathway can be uninstalled the inside pressure of elongator, and is convenient with trading the dismouting, set up the ball sealer in the pressure releasing pathway, guarantee that the internal pressure of elongator is unchangeable, and it is sealed respond well.
Description
Technical field
The utility model relates to a kind of hydraulic tool, in particular, relates to a kind of pressure release hydraulic elongator easy to assemble.
Background technology
The bolt tensioning jack that present stage adopts comprises bracing frame, swivel nut, driving lever, oil cylinder, piston, stretching head and oil connection substantially, oil cylinder is utilized directly to apply external force to bolt, the bolt of the power that is applied in is elongated in its elastic deformation area, diameter of bolt micro-deformation, thus make nut be easy to loosening.Again in disassembly process, after stretcher uses, inner chamber has pressure, first transit joint must be taken off pressure release and carry out dismounting again, very loaded down with trivial details.
Utility model content
The utility model for the deficiency of existing product, and provides a kind of rational in infrastructure, practical, safe and reliable a kind of pressure release hydraulic elongator easy to assemble.
A kind of pressure release of the present utility model hydraulic elongator easy to assemble, described stretcher comprises elongated body, nut sleeve, swivel nut, in described elongated body, lower semisection is provided with nut sleeve, in described elongated body, upper semisection is provided with swivel nut, described elongated body sidewall offers oil-in, and described swivel nut offers pressure release passage, and described pressure release passage and oil-in communicate, described pressure release passage is connected with pressure relief opening, and described pressure relief opening is connected by sealing plug with swivel nut.In described pressure release passage upper end, ball sealer is installed.The diameter of described ball sealer is not more than the internal diameter of pressure relief opening.Described pressure release passage upper end is provided with conical seal surface, and described conical seal surface and ball sealer are connected.Described sealing plug is interior hexagonal external screw thread plug screw.
The beneficial effects of the utility model are: (1) is rational in infrastructure, are easy to manufacture; (2) practical, pressure release passage can by the discharge degree of stretcher inside, and convenience is with changing dismounting; (3) in pressure release passage, ball sealer is set, ensure that the internal pressure of stretcher is constant, and sealing effectiveness is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: elongated body 1, nut sleeve 2, swivel nut 3, sealing plug 4, pressure relief opening 5, ball sealer 6, pressure release passage 7, oil-in 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
In the drawings, a kind of pressure release of the present utility model hydraulic elongator easy to assemble forms primarily of elongated body 1, nut sleeve 2, swivel nut 3, sealing plug 4, pressure relief opening 5, ball sealer 6, pressure release passage 7, oil-in 8.
Described stretcher comprises elongated body 1, nut sleeve 2, swivel nut 3, in described elongated body 1, lower semisection is provided with nut sleeve 2, in described elongated body 1, upper semisection is provided with swivel nut 3, described elongated body 1 sidewall offers oil-in 8, described swivel nut 3 offers pressure release passage 7, described pressure release passage 7 and oil-in 8 communicate, and described pressure release passage 7 is connected with pressure relief opening 5, and described pressure relief opening 5 is connected by sealing plug 4 with swivel nut 3.In described pressure release passage 7 upper end, ball sealer 6 is installed.The diameter of described ball sealer 6 is not more than the internal diameter of pressure relief opening 5.Described pressure release passage 7 upper end is provided with conical seal surface, and described conical seal surface and ball sealer 6 are connected, and form Mechanical contacted seals between conical seal surface and ball sealer 6, and sealing effectiveness than conventional seals circle effect more.Described sealing plug 4 is interior hexagonal external screw thread plug screw.
A kind of pressure release of the present utility model hydraulic elongator easy to assemble, rational in infrastructure, be easy to manufacture; Practical, pressure release passage can by the discharge degree of stretcher inside, and convenience is with changing dismounting; In pressure release passage, ball sealer is set, ensure that the internal pressure of stretcher is constant, and sealing effectiveness is good.
