Description
Technical Field
The utility model relates to the technical field related to flange sealing, in particular to a sealing protective sleeve for flange leakage detection.
Background
Flange (Flange), also known as Flange collar or Flange. The flange is a part for connecting the shafts and is used for connecting the pipe ends; there are also flanges for use on the equipment access ports for connection between two equipment, such as speed reducer flanges. The flange connection or the flange joint refers to detachable connection which is formed by connecting a flange, a gasket and a bolt with each other to form a group of combined sealing structures. The pipeline flange refers to a flange for a piping in a pipeline device, and is used on equipment to refer to an inlet and outlet flange of the equipment.
The Chinese patent with the authority of CN208750217U discloses a convex high-pressure flange connecting structure, which comprises a left flange and a right flange, wherein a connecting piece capable of connecting the left flange and the right flange is arranged between the left flange and the right flange; the connecting ends of the left flange and the right flange are respectively provided with a boss; grooves matched with the bosses are respectively formed in two sides of the connecting piece, and connecting piece holes communicated with through holes in the left flange or the right flange are formed in the grooves. The disadvantage of this patent lies in that the flange gasket seam (as shown in fig. 3) formed at the joint of two flanges lacks sealing structure, and the leakage phenomenon easily occurs, and the staff can not know the leakage condition of the joint of flanges at the first time, and is difficult to deal with in time.
In view of the foregoing, there is a need for a seal protection sleeve that can seal a flange gasket seam and can detect flange leakage in real time when the flange is in a leak condition.
Disclosure of Invention
The utility model provides a sealing protective sleeve for flange leakage detection, which is capable of sealing a flange gasket seam and grasping the leakage condition of a flange joint in real time, in order to overcome the defects that the flange gasket seam formed at the joint of two flanges in the prior art lacks a sealing structure, is easy to leak, and cannot be known by workers for the leakage condition of the flange joint at the first time and is difficult to treat in time.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a flange leak detection's sealed protective sheath, includes annular layering, be equipped with the response paster on the inside wall of annular layering, the port department at the both ends of annular layering all is provided with seal structure, the response paster is arranged in between the seal structure at both ends.
The sealing structures at the two ends are used for sealing the two flanges respectively, so that the flange gasket seam and the annular pressing strip form a sealed closed bin together, the sealing of the flange gasket seam is well realized, meanwhile, the pressure in the bin changes, or gas and liquid leak, the first time perception of the induction patch can be realized, and the leakage condition of the flange joint can be mastered in real time by workers.
Preferably, the annular pressing strip is made of stainless steel. Good corrosion resistance, high strength and high hardness.
Preferably, a pressure sensor is arranged on the sensing patch. The device is used for sensing the pressure change in the closed bin (consisting of a flange gasket seam and an annular pressing strip) or the leakage condition of gas and liquid in real time.
Preferably, the sealing structure comprises a sealing gasket matched with the port of the annular pressing strip, and the sealing gasket is fixed at the port of the annular pressing strip. The sealing gasket can be tightly attached to the surface of the regular flange plate, and the sealing effect is good.
Preferably, the sealing gasket is arranged at the inner side of the port of the annular pressing strip, the outer diameter of the sealing gasket is matched with the inner diameter of the annular pressing strip, and the outer side surface of the sealing gasket is fixedly connected with the inner side wall of the annular pressing strip. The flange gasket is tightly sleeved on the outer side of the regular flange plate, so that the flange gasket seam and the annular pressing strip form a sealed closed bin together, and the sealing effect is good.
Preferably, the sealing gasket is made of silica gel. Has good elasticity, high temperature resistance and corrosion resistance, convenient installation and good sealing effect.
The beneficial effects of the utility model are as follows: the flange gasket seam can be sealed; leakage conditions at the flange connection part can be mastered in real time; the corrosion resistance is good, the strength and the hardness are high; the sealing effect is good; the installation is convenient.
