Technical Field
The invention relates to the field of ship manufacturing, in particular to a double-glasses short-tube flange device for a piping system.
Background
According to the requirements of classification society regulations, two pipelines are completely and physically separated in some important pipeline systems of ships, but two pipelines are connected in special cases, so that a detachable short pipe is required to be arranged in the pipeline of the type. When the detachable short pipe is used normally, the detachable short pipe is installed near a disconnected pipeline for standby, and the disconnected pipeline is sealed by a blind flange and is tightly fastened by a bolt gasket. When the disconnected pipeline needs to be connected under special conditions, the bolt and the blind plate are detached, the detachable short pipe is connected to the disconnected pipeline to be communicated, and the bolt gasket is installed. In the conventional detachable short pipe connection mode, a blind flange is required to be arranged on a disconnected pipeline, and a large number of bolts are required to be detached when the detachable short pipe is replaced; the spare detachable short pipe needs to be specially fixed, two ends of the short pipe need to be protected in a sealing mode, the heavy-caliber pipeline detachable short pipe is heavy in weight and needs to be carried and installed through special tools; due to the stress effect of the pipeline, the installation precision is limited; in conclusion, the traditional detachable short pipe form needs additional equipment such as a blind flange and an installation tool, and is inconvenient to disassemble and install and inconvenient for a crew to operate.

the blind plate group comprises a first flange blind plate and a second flange blind plate which are horizontally arranged at intervals up and down, and a vertical supporting pipe is connected between the first flange blind plate and the second flange blind plate;
the side surface of the first flange plate is connected with the side surface of the first flange blind plate through a horizontal first connecting plate; the first flange plate, the first connecting plate and the first flange blind plate are all positioned on the same horizontal plane;
the side surface of the second flange plate is connected with the side surface of the second flange blind plate through a horizontal second connecting plate; the second flange plate, the second connecting plate and the second flange blind plate are all positioned on the same horizontal plane;
the middle parts of the first connecting plate and the second connecting plate are both provided with through hinge openings;
the device also comprises a support, wherein a bolt is arranged on the support and fixed on the support after penetrating through the two hinge interfaces.
The support tube is provided with four.
The contact points of the four supporting tubes and the first flange blind plate are four vertexes of a rectangle.
The middle point of the rectangle is positioned at the center of the first flange blind plate.
Compared with the prior art, the pipeline connecting device has the advantages that as long as the device is hinged near the two pipelines through the bracket, when the two pipelines need to be connected, the two pipelines can be connected by rotating the device to enable the flange group to be rotated to be fixed between the two pipelines; when the connection of the two pipelines needs to be blocked, the device disclosed by the invention is rotated to transfer the blind plate group of the device disclosed by the invention between the two pipelines for fixing, so that the sealing can be carried out, and the whole process is more accurate and convenient than the manual position determination and has higher efficiency. In addition, the device has small volume, light weight and more convenient use, and because the distance between the two flanges is fixed, the construction difficulty is reduced when the through position and the blind position are exchanged, and the blind plate and the gaskets at the two sides can not be inserted into the blind plate and the gaskets at the two sides by prying a certain gap when the common spectacle flange is constructed. For systems requiring complete isolation, this is generally used as a reliable means of isolation.
