The hose connector is one of two main components of a hydraulic pipeline, and the hose connector is mainly a buckle-press type hose connector which meets the requirements of stable normal connection, strong sealing property, reasonable size, small pressure loss, good process performance, easiness in occurrence and the like. The existing hose joint has certain defects when in use, when an oil field pipeline is repaired in a non-excavation mode, the oil field pipeline cannot be connected through a flange when buried underground, and the flexible hose is easy to damage due to external contact, so that the cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a novel flexible hose nipple is restoreed in non-excavation of oil field pipeline can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel flexible hose joint is restoreed in non-excavation of oil field pipeline, includes former pipeline, the inner wall of former pipeline is provided with flexible hose, and the one end welding of former pipeline has the joint overcoat, flexible hose's inner wall is located the position department that connects the overcoat and connects the inner core, and connects and be provided with the joint seal cover between overcoat and the joint inner core, connect the overcoat and connect the inner core respectively with the hookup location department that connects the seal cover seted up the seal groove, and the internally mounted of seal groove has the sealing washer, the hookup location department of former pipeline and joint overcoat is equipped with the welding department, the antiskid groove has been seted up to the inner wall that connects the overcoat, connect the inner core and connect the corresponding side surface position department of overcoat and seted up the joint seal groove, and connect the inner.
Preferably, the original pipeline is fixedly connected with the joint sealing sleeve through the joint outer sleeve.
Preferably, the number of the anti-skid grooves and the number of the joint sealing grooves are a plurality of groups, and the joint sealing grooves compress the flexible hoses in the anti-skid grooves through expansion deformation.
Compared with the prior art, the utility model discloses following beneficial effect has: this novel flexible hose joint is restoreed in non-excavation of novel oil field pipeline, in the use, connect overcoat end-mounting to have the joint seal cover, can prevent during external medium from flowing into flexible hose, destroy flexible hose, because flexible hose takes interior expanding with joint seal, the user stretches into the joint inner core with special interior expanding tool, the accessible connects the seal groove and warp, the external diameter grow, then compress flexible hose in anti-skidding groove, thereby flexible hose and joint overcoat, joint inner core closely laminate together and play sealed effect, flexible hose joint simple structure is restoreed in non-excavation of whole novel oil field pipeline, and convenient operation, the effect of use is better for the traditional mode.
