Description

Technical Field

[0001] The utility model relates to the technical field of pipeline dredging, in particular to a pipe elbow capable of unblocking used in pipeline transportation. Background Art

[0002] When transporting water through pipelines, the pipelines are often blocked by rust or impurities, and the pipelines need to be untied for unblocking. When untiing the pipelines, the valve part is usually removed, and the unblocking tool is inserted into the gap left by the structural length of the valve. Since the gap is very short, the operation is inconvenient and the entire unblocking operation is time-consuming and labor-intensive. Utility Model Content

[0003] In order to solve the problems of inconvenient operation and long operation time when unblocking pipelines, the utility model provides an unblocking pipe elbow for pipeline transportation.

[0004] The technical solution provided by the utility model is: an unblockable pipe elbow for pipeline transportation, comprising a main body, a vertical channel, a curved channel and a horizontal channel provided on the main body, the vertical channel, the curved channel and the horizontal channel forming an inner channel of the elbow, a horizontal hole provided on the main body in the opposite direction of the horizontal channel, the horizontal hole being concentric with the horizontal channel, the main body being connected to a pressure cover A by bolts at the position of the horizontal hole, the pressure cover A and the horizontal hole being connected through a sealing ring clearance fit, a vertical hole provided on the main body in the opposite direction of the vertical channel, the vertical hole being concentric with the vertical channel, the main body being connected to a pressure cover B by bolts at the position of the vertical hole, the pressure cover B and the vertical hole being connected through a sealing ring clearance fit.

[0005] The main body has a cavity on the inside of the horizontal hole and the vertical hole. When the cavity extends to the curved channel, a horizontal end face and a vertical end face are formed. A magnesium tile is placed in the cavity of the main body. The magnesium tile is made of magnesium metal and is arc-shaped. The arc-shaped inner surface of the magnesium tile is consistent with the structure of the curved channel. The two ends of the arc of the magnesium tile are respectively against the horizontal end face and the vertical end face. The pressure cover A extends toward the magnesium tile and presses on the magnesium tile. The diameter of the vertical hole can place the magnesium tile into the cavity.

[0006] The main body has a through hole on the curved channel, and a support is fixedly installed in the through hole. The support extends into the curved channel, and the support is fixedly connected to a spring in the curved channel. The other side of the spring is connected to a steel ball, and the steel ball is located near the large diameter curved surface of the curved channel.

[0007] The conductivity probe is connected to the gland B through a threaded sealing ring.

[0008] The beneficial effects of the present invention are as follows: when the horizontal channel is blocked, the pressure cover A is opened, and the unblocking tool is passed into the horizontal channel through the horizontal hole to unblock it; when the vertical channel is blocked, the pressure cover B is opened, and the unblocking tool is passed into the vertical channel through the vertical hole to unblock it. The unblocking operation can be completed without opening other valves on the pipeline, and the unblocking operation is convenient and the operation time is short. Magnesium tiles are arranged in the elbow, and the magnesium metal reacts with the oxygen in the water, thereby making the iron elements in the pipeline lose the opportunity to oxidize, which can play a role in rust prevention. An elastic steel ball is arranged in the elbow, and the steel ball shakes and hits the inner wall of the elbow to generate shock waves. The shock waves are transmitted to the inner wall of the pipeline, which can vibrate rust and impurities out of the pipeline, further playing a role in anti-blocking.

DETAILED DESCRIPTION

[0012] like Figures 1-2 As shown, a removable pipe elbow for pipeline transportation includes a main body 1, on which a vertical channel 2, a curved channel 15 and a horizontal channel 3 are provided. The vertical channel 2, the curved channel 15 and the horizontal channel 3 constitute an inner channel of the elbow. The main body 1 is provided with a horizontal hole 4 in the opposite direction of the horizontal channel 3. The horizontal hole 4 is concentric with the horizontal channel 3. The main body 1 is connected to a pressure cover A6 by bolts at the position of the horizontal hole 4. The pressure cover A6 is connected to the horizontal hole 4 through a sealing ring clearance fit. The main body 1 is provided with a vertical hole 5 in the opposite direction of the vertical channel 2. The vertical hole 5 is concentric with the vertical channel 2. The main body 1 is connected to a pressure cover B7 by bolts at the position of the vertical hole 5. The pressure cover B7 is connected to the vertical hole 5 through a sealing ring clearance fit.

[0013] When the horizontal channel 3 is blocked, the pressure cover A6 is opened, and the unblocking tool is passed into the horizontal channel 3 through the horizontal hole 4 to unblock it. When the vertical channel 2 is blocked, the pressure cover B7 is opened, and the unblocking tool is passed into the vertical channel 2 through the vertical hole 5 to unblock it. The unblocking operation can be completed without opening other valves on the pipeline. The unblocking is convenient and the operation time is short.

[0014] The main body 1 has a cavity 17 on the inside of the horizontal hole 4 and the vertical hole 5. When the cavity 17 extends to the curved channel 15, a horizontal end face 9 and a vertical end face 10 are formed. The main body 1 has a magnesium tile 8 placed in the cavity 17. The magnesium tile 8 is made of magnesium metal and is arc-shaped. The arc-shaped inner surface of the magnesium tile 8 is consistent with the structure of the curved channel 15. The two ends of the arc of the magnesium tile 8 are respectively against the horizontal end face 9 and the vertical end face 10. The pressure cover A6 extends toward the magnesium tile 8 and presses on the magnesium tile 8. The diameter of the vertical hole 5 can place the magnesium tile 8 into the cavity 17.

[0015] A magnesium tile 8 is arranged in the elbow, and the magnesium metal reacts with the oxygen in the water, thereby depriving the iron element of the pipeline of the opportunity to be oxidized, which can play a role in rust prevention.

[0016] The main body 1 has a through hole 11 on the curved channel 15, and a support member 16 is fixedly installed in the through hole 11. The support member 16 extends into the curved channel 15. The support member 16 is fixedly connected to the spring 12 in the curved channel 15. The other side of the spring 12 is connected to the steel ball 13. The steel ball 13 is located near the large-diameter curved surface of the curved channel 15. The water flows in the curved elbow to generate turbulence, which causes the steel ball 13 to shake. The steel ball 13 shakes and hits the inner wall of the elbow to generate shock waves. The shock waves are transmitted to the inner wall of the pipe, which can vibrate rust and impurities out of the pipe, further playing an anti-blocking role.

[0017] The gland B7 is connected to a conductivity probe 14 via a threaded sealing ring to monitor changes in water quality.
