Abstract
The utility model discloses a large-diameter pipe locking key sealing and connecting device which consists of a steel pipe and a pipe collar which are sleeved and connected with one another. One end of the pipe collar is connected with a locking key at the tail end of the steel pipe; the locking key connecting mode is that a groove is arranged on the outer circumference of the tail end of the steel pipe, and an interior groove which corresponds to and is in the same shape with the groove at the tail end of the steel pipe and is provided with a slanting through hole which runs through the wallof the pipe collar is arranged on the inner circumference of the pipe collar along the circumferential direction; a groove is arranged at the outer side of the groove at the tail end of the steel pipe; and a seal ring is arranged in the groove. The large-diameter pipe locking key sealing and connecting device is not only strong in connecting strength and reliable in sealing performance but also easy to make. The large-diameter pipe locking key sealing and connecting device can solve the problem in connecting and sealing reliability of a glass steel pipe with the diameter bigger 300mm and the working pressure bigger than 7 MPa. The large-diameter pipe locking key sealing and connecting device is simple in structure and convenient to install.
Description
Technical field
The utility model relates to the seal arrangement that a kind of fiber reinforced plastic pipe connects, and particularly relates to a kind of large diameter pipeline locking key sealed connection device.
Background technique
At present, known fiber reinforced plastic pipe connects has with seal form: flanged ends face, socket joint be bonding to be connected and sealing, socket joint O type circle seal, API screw thread and seal gease are tightly connected.All there is the pressure rating joint dimension in above-mentioned Connecting format or the narrow limitation of effect is installed, and during greater than 300 millimeters fiber reinforced plastic pipe, because of thrust load is big, then can cause the loosening or pull-off of joint greater than 7MPa, pipe diameter when being applied to pressure.Thereby cause the leakage of pipeline.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of large diameter pipeline locking key sealed connection device is provided, and solves the problem of above high-pressure fiberglass pipe sealing reliability of DN300 and installation efficiency.
Large diameter pipeline locking key sealed connection device of the present utility model, be by steel pipe and pipe box cupling mutually intussusception connect and to constitute, terminal locking key is connected one end of pipe box cupling with steel pipe, it is to be provided with groove on the excircle of steel pipe end that described locking key connects, its circumferencial direction of pipe box cupling inner circumference upper edge be provided with corresponding mutually with the terminal groove location of steel pipe, shape is identical and the internal recess of the oblique through hole of formation through tube box cupling tube wall on it; The outside at the terminal groove of steel pipe is provided with groove, is provided with seal ring in groove.
As further improvement of the utility model, it is to be interval with two parallel grooves on the excircle of steel pipe end that described locking key connects, its circumferencial direction of pipe box cupling inner circumference upper edge be provided with corresponding mutually with the terminal two parallel groove positions of steel pipe, shape is identical and the internal recess of the oblique through hole of formation through tube box cupling tube wall on it.
Large diameter pipeline locking key sealed connection device of the present utility model, not only join strength height, sealing are reliably, and make easily, can solve the fiber reinforced plastic pipe diameter and connect the reliability of sealing greater than the fiber reinforced plastic pipe of 7MPa greater than 300 millimeters, working pressure, simple in structure easy for installation.
