Description

Technical Field

[0001] The utility model relates to a highly sealed expanded pipe fitting, belonging to the technical field of expanded pipe fittings. Background Art

[0002] Flare-type pipe fittings are widely used in high-pressure piping applications in industrial sectors such as shipbuilding, offshore oil, metalworking, and mining. Flare-type pipe fittings are suitable for hydraulic, lubrication, high-pressure water flushing, and high-pressure air piping. Flare-type pipe fittings have been certified by numerous auditing agencies for their high reliability, inherent cleanliness, and flexibility. Their pre-fabrication, assembly, and installation are quick and easy. Flare-type connections eliminate the need for welding, eliminating subsequent pickling and flaw detection processes.

[0003] There are still some problems in the use of existing flared pipe fittings. When in use, the flared pipe needs to be threadedly connected to the pipe fitting so that the other side of the flared pipe can be connected to other pipes. However, the connection is generally a threaded connection, and the flared pipe needs to be rotated as a whole, which is relatively troublesome. At the same time, the threaded connection method cannot clamp the sealing ring, so it is easy to leak. Utility Model Content

[0004] The purpose of the present invention is to provide a highly sealed flared pipe fitting. The present invention has a simple structure, is easy to use, can quickly connect the pipeline to the flared pipe, and can improve the sealing between the pipe fitting and the flared pipe to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A highly sealed flared pipe fitting comprises a pipe fitting body and a flared pipe, the outer side of the flared pipe being fixedly connected with a connecting plate, the interior of the connecting plate being provided with a sliding groove, the outer side of the connecting plate being slidably connected with a slider, the bottom of the slider being slidably clamped with a lifting rod, the end of the lifting rod away from the slider being fixedly connected with a No. 1 clamping cover and a No. 2 clamping cover, the outer side of the No. 1 clamping cover being fixedly connected with a clamping rod, the interior of the No. 2 clamping cover being provided with a positioning hole, the outer side of the lifting rod being fixedly connected with a reset spring, the outer side of the slider being fixedly connected with a No. 1 threaded pipe, and the interior of the No. 1 threaded pipe being threadedly connected with a No. 1 screw.

[0007] Furthermore, a sealing cover is fixedly connected to the outer side of the No. 1 clamping cover and the No. 2 clamping cover, an L-shaped plate is fixedly connected to the outer side of the slider, a No. 2 threaded tube is fixedly connected to the outer side of the L-shaped plate, the inner thread of the No. 2 threaded tube is connected to the No. 2 screw, and the outer side of the No. 2 screw is fixedly connected to an extrusion rod.

[0008] Furthermore, the connecting plates are symmetrically distributed on the outside of the expanded tube, and the lifting rods cross the inside of the slide groove.

[0009] Furthermore, the No. 1 clamping cover and the No. 2 clamping cover are symmetrically distributed on the outside of the flared tube, and the top of the return spring is fixedly connected to the outside of the connecting plate.

[0010] Furthermore, the clamping rod and the positioning hole are on the same numerical plane, and the No. 1 screw is located directly above the lifting rod.

[0011] Furthermore, the L-shaped plates are symmetrically distributed on the outside of the slider, and the No. 2 screw crosses the inside of the L-shaped plates.

[0012] Furthermore, the extrusion rods are movably connected to the outer side of the connecting plate through a No. 2 screw, and the extrusion rods are symmetrically distributed on the outer side of the connecting plate.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model is provided with a pipe body and a flared tube. When the pipe body and the flared tube need to be installed, the pipe body is first clamped to the inside of the flared tube, and the No. 1 screw is rotated by turning the No. 1 screw to rotate inside the No. 1 threaded tube, thereby moving the No. 1 screw. The movement of the No. 1 screw squeezes the lifting rod inside the slider, and the lifting rod drives the No. 1 clamping cover and the No. 2 clamping cover to be close to the outside of the pipe body. Since a clamping rod is fixedly connected to the outside of the No. 1 clamping cover and a positioning hole is opened inside the No. 2 clamping cover, the clamping rod will enter the inside of the positioning hole, so that the No. 1 clamping cover and the No. 2 clamping cover maintain stability on the outside of the pipe body, thereby achieving the effect of convenient connection between the pipe body and the flared tube.

[0015] (2) The utility model is provided with a flaring tube. By moving the slider, the slider drives the lifting rod to move inside the slide groove. At this time, the lifting rod drives the No. 1 clamping cover and the sealing cover outside the No. 2 clamping cover to enter the interior of the flaring tube. At this time, by rotating the No. 2 screw, the No. 2 screw is rotated and moved inside the No. 2 threaded tube. The movement of the No. 2 screw drives the extrusion rod to move, so that the extrusion rod squeezes the outside of the connecting plate, thereby positioning the slider, and the sealing cover can seal the flaring tube and the pipe body, thereby preventing water leakage, thereby improving the sealing performance.
