Description

Pipeline interface connecting device

Technical Field

The utility model relates to the technical field of pipeline connection, in particular to a pipeline interface connecting device.

Background

In the existing pipelines of heating, air conditioning or industrial systems, the interfaces of devices such as control valves, flow meters and the like are usually connected with the interfaces of the pipelines through screw threads or flange structures, and it is required to ensure that the connection structures at the interfaces of the control valves, the flow meters and the like are corresponding to each other, and the screw thread structures and the flange structures cannot be directly connected.

Under the prior art, realize the lug connection of helicitic texture and flange structure through taking neck screw thread steel pipe flange, nevertheless use neck screw thread steel pipe flange and pass through threaded connection back with equipment or pipeline interface, for the requirement of field erection such as satisfying the angle, when carrying out flange joint through neck screw thread steel pipe flange and another interface, the unable unanimous condition that corresponds of connecting hole that easily appears flange structure, need actually join in marriage at the scene, need weld again after the flange cutting sometimes, seriously influence efficiency and operation, the screw thread direct seal reduces easily to produce the leakage in reliability under high microthermal environment.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a pipe joint connection device, which enables a threaded structure and a flange structure to be directly connected to each other, so as to solve the problems of the background art.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a pipeline interface connection device, includes the flange body, still include with the T type ring cover of the first through-hole block that flange body central point put, T type ring cover is including the ring shoulder portion of seting up the second through-hole and the ring neck portion of seting up the screw thread mounting hole, the lateral surface of ring neck portion is connected, the medial surface is provided with the helicitic texture for rotating with the inner wall of first through-hole.

Preferably, an annular sealing gasket is fixedly arranged between the second through hole and the threaded mounting hole.

Preferably, the first through hole, the second through hole and the threaded mounting hole are coaxially arranged.

According to the technical scheme, the flange body is sleeved on the T-shaped ring sleeve with the threaded structure for matching use, so that the threaded structure and the flange structure can be directly connected, the flange structure can rotate around the ring neck of the T-shaped ring sleeve for adjustment, the requirement of the site specific installation angle of equipment is met, and the working efficiency is effectively improved.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

The pipe interface connecting device shown in fig. 1-2 comprises a flange body and a T-shaped ring sleeve clamped with a first through hole in the center of the flange body, wherein the T-shaped ring sleeve comprises a ring shoulder part provided with a second through hole and a ring neck part provided with a threaded mounting hole, the outer side surface of the ring neck part is rotatably connected with the inner wall of the first through hole, a threaded structure is arranged on the inner side surface of the ring neck part, the threads are designed according to standard caliber threads, the flange body is provided with a plurality of mounting holes and can freely rotate around the neck part, and the flange body can be rotated to meet the requirement of a specific mounting angle on site during installation and use.

In a specific use, the first through hole, the second through hole and the threaded mounting hole are generally coaxially arranged; an annular sealing gasket is fixedly arranged between the second through hole and the thread mounting hole, a good sealing effect is realized after the matched thread mechanism is screwed down, and the sealing gasket can meet the working requirements of high and low temperature environments; the clamping position of the T-shaped ring sleeve and the first through hole is subjected to chamfering treatment, so that abrasion is reduced, and the service life is prolonged; the caliber of each through hole is selected and set according to the industry standard and the specific use requirement.

The first embodiment is as follows:

as shown in fig. 3, the interfaces at the two ends of the pipeline are flange structures, the interfaces at the two ends of the equipment which is installed and connected with the pipeline are thread structures, a pipeline interface connecting device with matched size is selected according to the calibers of the equipment interface and the pipeline interface, and then the interfaces at the two ends of the equipment are respectively connected with the pipeline interface according to the one-to-one correspondence relationship between the threads and the flange structures;

example two:

as shown in fig. 4, the interfaces at the two ends of the pipeline are in a threaded structure, the interfaces at the two ends of the equipment which is installed and connected with the pipeline are in a flange structure, firstly, a pipeline interface connecting device with matched size is selected according to the calibers of the equipment interface and the pipeline interface, and then, the interfaces at the two ends of the equipment are respectively connected with the pipeline interface according to the one-to-one correspondence relationship between the threads and the flange structure;

in the above embodiment, if the specific installation angle of the equipment needs to be met, only the flange body of the pipeline interface connecting device needs to be rotated; the flange structures are locked by bolts penetrating through the mounting holes and are provided with standard flange gaskets for sealing.
