The volume of thermal expansion can not discharge, will push boiler displacement, or the phenomenon that boiler inclination occur, for this reason, it may be necessary to install one additional
Flexible discharges the device of thermal volume expansion.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of simple expansion joint is provided, including swollen
Swollen section main body one, expansion joint main body two, screw arbor assembly, special sealing ring inside set the company of one right end of expansion joint main body of through-hole one
One right side of spindle sets internal channel one, and two left side of connecting shaft for two left end of expansion joint main body for setting through-hole two in centre sets septal fossula
The intermediate seal pad both ends of slot two, special sealing ring respectively set insert seal circle, and when assembling, the insert seal circle of one end is packed into
Internal channel one, the insert seal circle of the other end are packed into internal channel two, the screw rod of screw arbor assembly successively penetrate flange hole one,
Other end nut locking after flange hole two, the utility model is using elasticity tight after the feature sealing ring overall package axially connected
Deformable seal, structure is simple, and installation and removal are convenient, can have minibuffer to expand with heat and contract with cold, and is suitble to boiler applications.
In order to achieve the above objectives, the technical solution of the utility model is：A kind of simple expansion joint, including expansion joint main body
One, expansion joint main body two, screw arbor assembly, special sealing ring, the connecting shaft one for inside setting one right end of expansion joint main body of through-hole one are right
End face sets internal channel one, and two left side of connecting shaft for two left end of expansion joint main body for setting through-hole two in centre sets internal channel two, institute
The intermediate seal pad both ends for stating special sealing ring respectively set insert seal circle, when assembling, in the insert seal circle of one end is packed into
The insert seal circle of groove one, the other end is packed into internal channel two, and the screw rod of the screw arbor assembly successively penetrates flange hole
One, other end nut locking after flange hole two.
Further setting, the end outer circle of the connecting shaft two set the guard ring of protrusion.
Further it is arranged, sets through-hole three in the special sealing ring, three both ends of through-hole respectively set stepped hole.
The utility model has the beneficial effects that：The utility model is using tight after the feature sealing ring overall package axially connected
Flexible deformation sealing, structure is simple, and installation and removal are convenient, can have minibuffer to expand with heat and contract with cold, and is suitble to boiler applications.
