Abstract

PE pipe elbow position plugging device. At present, the PE pipeline is generally leak-blocked by adopting a half joint, the half joint has a good effect on a straight pipe section, but has no firm support at an elbow, and cannot bear the impact force of water flow when the pipeline is injected with water. The utility model discloses the constitution includes: fixed cover (1) and socket joint steel pipe (2), fixed cover is arranged on the external diameter of PE pipe both ends port, and the radial and terminal surface of fixed cover all processes and has a set of through-hole, the one end and the PE inside pipe wall socket joint of socket joint steel pipe are connected, and the welding has flange (5) on the outer wall of PE union coupling one side, processing has a set of through-hole on the flange, a set of O type circle (4) has been arranged to the part that the socket joint steel pipe injects PE pipe, fixed cover with the flange bolted connection of socket joint steel pipe, the socket joint steel pipe is 2, the socket joint steel pipe other end and elbow (3) welding. The utility model is used for PE pipe elbow position leaking stoppage.

Description

PE pipe elbow position plugging device

Technical Field

The utility model particularly relates to a PE pipe elbow position plugging device.

Background

The PE pipe has the advantages of no toxicity, corrosion resistance, aging resistance and the like, and is wide in application field, the PE pipe is mainly connected in a hot melting or electric melting mode, the consistency requirement of the hot melting connection on the material of the pipe fitting is high, a special welding machine is required for the electric melting connection, the price of the electric melting pipe fitting is several times or even dozens of times of that of a common pipe fitting, and the quality of an interface is directly influenced by the operation proficiency. At present, the PE pipeline is generally leak-stopped by adopting a half joint, the half joint has a good effect on a straight pipe section, but if the elbow is not firmly supported, the impact force of water flow cannot be borne when the pipeline is injected with water.

Disclosure of Invention

The utility model aims at providing a PE pipe elbow position plugging device.

The above purpose is realized by the following technical scheme:

the utility model provides a PE piping elbow position plugging device which constitutes and includes: fixed cover and socket joint steel pipe, fixed cover is arranged on the external diameter of PE pipe both ends port, and the radial direction processing of fixed cover has a set of through-hole, and the terminal surface processing has a set of thread hole, the one end and the PE inside pipe wall socket joint of socket joint steel pipe are connected, and the welding has the flange on the outer wall of PE union coupling one side, processing has a set of through-hole on the flange, a set of O type circle has been arranged to the part that the socket joint steel pipe injects PE pipe, fixed cover with the flange bolted connection of socket joint steel pipe, fixed cover and PE pipe bolted connection, the socket joint steel pipe is 2, the socket joint steel pipe other end and elbow welding.

Has the advantages that:

the utility model relates to a PE pipe elbow position plugging device, plugging device's connecting piece divide into fixed cover and socket joint steel pipe two parts, and fixed cover is fixed cover on PE pipe port department external diameter, and socket joint steel pipe one end is connected with PE inside pipe wall socket joint, other end processing groove and steel pipe welding, and the socket joint position is equipped with O type circle, guarantees that the socket joint is connected sealedly tightly. The utility model provides high PE pipe elbow position joint strength reduces the tube coupling cost, makes the tube coupling more simple and convenient simultaneously, and the practicality is revealed to shutoff PE pipe elbow position.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention;

wherein: 1. the device comprises a fixing sleeve, 2, a socket steel pipe, 3, an elbow, 4, an O-shaped ring, 5 and a flange.

The specific implementation mode is as follows:

example 1:

the utility model provides a PE piping elbow position plugging device which constitutes and includes: the PE pipe comprises a fixed sleeve 1 and socket steel pipes 2, wherein the fixed sleeve is arranged on the outer diameter of ports at two ends of a PE pipe, a group of through holes are processed in the radial direction of the fixed sleeve, a group of thread holes are processed on the end face of the fixed sleeve, one end of the socket steel pipe is in socket connection with the inner wall of the PE pipe, a flange 5 is welded on the outer wall of one side connected with the PE pipe, a group of through holes are processed on the flange, a group of O-shaped rings 4 are arranged on the part of the socket steel pipe inserted into the PE pipe, the fixed sleeve is in bolt connection with the flange of the socket steel pipe, the fixed sleeve is in bolt connection with the PE pipe, the number of the socket steel pipes is 2, and the other end of the socket steel pipe is welded with an elbow 3;

the connecting piece is divided into two parts, one part is a fixed sleeve sleeved on the outer diameter of the port of the PE pipe, 8 through holes through which M18 bolts penetrate are radially and uniformly distributed on the circular ring, 16M 18 thread holes are uniformly distributed on the end face, one end of the other part of socket steel pipe is in socket joint connection with the inner wall of the PE pipe, a groove is machined at the other end of the socket steel pipe and is welded with the steel pipe, 3O-shaped rings with phi 18mm are arranged at the socket joint part, tight seal of the socket joint connection is guaranteed, and 16 holes with phi 20mm are axially drilled on the outer circle and are matched with the through holes of the fixed sleeve. During installation, the fixing sleeve is installed on ports at two ends of the PE pipe, holes are drilled in 8 radial through holes of the PE pipe for 10-15 mm in depth respectively, the sleeve is fixed on the PE pipe through bolts, axial displacement of the connecting piece is limited, the PE pipe is installed after the socket piece and the steel pipe are welded, 16 connecting bolts are screwed down, and finally the elbows are installed and welded with the steel pipes at two ends.
