Further, the first trapezoidal screw bearing, trapezoidal screw and the second trapezoidal screw bearing are upper and lower two groups pairs
Claim setting.
The beneficial effects of the utility model are：
A kind of Double End compound seal earthenware duct telescopic joint provided by the utility model, compensation extraction duct axial direction,
Dilatation caused by lateral, angular etc..Absorption equipment vibrates, and reduces influence of the vibration equipment to pipeline.Double End is compound close
Earthenware duct telescopic joint is sealed, adjusts stretch freely manually, be convenient for changing and install, the charging especially suitable for pump discharges, gate valve
Replacement and pump connection, realize gate valve quick-replaceable and pump connection.Double End compound seal earthenware duct telescopic joint,
Effective to solve to replace difficulty since space limits, maintenance is laborious time-consuming.Double End compound seal earthenware duct telescopic joint, liner
Ceramic layer is wear-resisting engineering ceramics, hardness (HRA) >=84, wear-resisting property be it is high cough up 10 times of wear-resistant cast iron alloy pipe fitting with
On.Using 12mm thickness ceramic layers, practical wear-resisting physical life is equivalent to 80mm thickness abrasion resistant cast steels.Because pipeline expands with heat and contract with cold
And the urgent termination of pumping of accident, for pipeline, with regard to the impact force of the stress of generation tube wall, push-pull effort and fluid；Tube wall stress is big
It is small, the intensity of pipeline is influenced, the impact force increase of push-pull effort and fluid, the fixing bracket of pipeline will be made big, to bear
The impact force of push-pull effort caused by pipeline extension and fluid；So it is compensated using Double End compound seal earthenware duct telescopic joint
Change opening amount method, to reduce the impact force of tube wall stress and thrust and fluid.Shock resistance：Toughening ceramic formula ensures ceramics not
Broken, unique design and good buffer layer can resist the impacts of bulk materials；Acid and alkali-resistance selects different wear-resisting
Ceramic material has different corrosive mediums the strong corrosive mediums such as excellent antiseptic property, acidproof, alkali, salt and halogen corrosion
Characteristic.
Description of the drawings
Fig. 1 is the utility model overall structure diagram；
Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
With reference to shown in Fig. 1, a kind of Double End compound seal earthenware duct telescopic joint, the ceramic inner sleeve including coaxial arrangement
