Abstract
The utility model discloses a sleeve expansion joint structure provided with sensors. The sleeve expansion joint structure comprises an inner pipe and an outer pipe which are mutually nested and are in pilot fit, wherein a step is arranged at one end of the outer pipe, an annular limiting boss is arranged at the other end of the outer pipe, and an inwards recessed annular connecting groove is formed in the outer pipe at the outer end of the step; an annular positioning boss is arranged at the extending end of the inner pipe, and internal threads are formed in the other end of the inner pipe; a spring is clamped between the annular limiting boss and the annular positioning boss, sealing grooves are formed in the annular circumferential surfaces of the annular limiting boss and the annular positioning boss, and O-shaped rings are clamped in the sealing grooves respectively; limited posts are arranged on the inner end surface of the annular limiting boss, inwards recessed mounting holes are formed in the limited posts, and pressure sensors are mounted in the mounting holes. According to the sleeve expansion joint structure, the stability of the whole structure in guiding movement process can be guaranteed, and the sealing property is enhanced; and the pressure sensors are mounted, measures can be taken timely when the pressure is too high, and an expansion joint is prevented from being damaged, so that the service life is prolonged, and the cost is reduced.
Description
Technical field
The utility model relates to pipeline field, relates in particular to a kind of sleeve expansion joint structure of belt sensor.
Background technique
Slip joint is applied in machinery industry conveyance conduit, and what cause for compensates expands with heat and contract with cold, and existing expansion joint structure is simple, it is installed and coordinates inconvenience, and overall structure poor stability, in the time being subject to larger pressure, its sealability can not guarantee, can not meet usage requirement.
Model utility content
The purpose of this utility model is the deficiency in order to make up prior art, and a kind of sleeve expansion joint structure of belt sensor is provided.
The utility model is achieved through the following technical solutions:
A kind of sleeve expansion joint structure of belt sensor, include the inner and outer tubes that mutual sheathing guiding coordinates, one end of described outer tube is provided with step, the other end is provided with annular stop boss, and the outer tube of step outer end is provided with the annular connecting groove caving inward, the inserting end of described inner tube is provided with circular orientation boss, the other end is provided with internal thread, between described annular stop boss and circular orientation boss, be installed with spring, and the annular circumferential face of annular stop boss and circular orientation boss is provided with seal groove, in described seal groove, be installed with respectively O shape circle, the interior edge face of described annular stop boss is provided with limited post, in described limited post, be provided with the mounting hole caving inward, in described mounting hole, pressure transducer is installed.
The utility model has the advantages that:
The utility model reasonable in design, by annular stop boss, circular orientation boss with and between the structural design of spring, the stability of its overall structure in the time of guiding movement can be guaranteed, by the structure of seal groove, sealability can be strengthened, by setting pressure sensor, in the time that pressure is excessive, can take measures in time, avoid damaging slip joint, thereby improve working life, reduced cost.
