Description
Technical Field
The utility model belongs to the technical field of it is sealed, a pressure line restraint ring type is to pressing seal structure is related to.
Background
The sealing element of the non-welding connection sealing structure of the large-caliber high-pressure pipeline is generally divided into two major types of metal and nonmetal, wherein the metal sealing has high pressure resistance, good reliability and long service cycle. The metal sealing is divided into two major types of flange butt-pressing and pipeline butt-pressing, and the two types of sealing have advantages and disadvantages respectively. The existing commonly used pipeline opposite-pressure sealing structure is a lens type seal, which is an excellent sealing structure and is commonly used for sealing chemical, petroleum and hydraulic pipelines. However, the processing requirement of the lens sealing gasket of the lens type sealing pair is high, the processing requirement of the pipeline joint surface is also high, and the application range of the pipeline opposite-pressure sealing structure is limited.
Disclosure of Invention
The utility model aims at solving the technical problem, a restraint ring type counter-pressure sealing structure related to a pressure pipeline is designed.
The utility model discloses a solution: the pressure pipeline restraint ring type counter-pressure sealing structure is characterized by comprising a tensioning flange 1, a tensioning screw 2, a metal pipeline 3, a metal sealing ring 4 and a sealing ring restraint ring 5; the two tensioning flanges 1 are respectively fixed on two metal pipelines 3 which need to be connected and sealed; firstly, a metal sealing ring 4 and a sealing ring restraining ring 5 are arranged on any metal pipeline 3, the other metal pipeline 3 is inserted into the sealing ring restraining ring 5 to contact the metal sealing ring 4, and the two tensioning flanges 1 are tensioned through tensioning screws 2.
The sealing ring confinement ring 5 is between the two tensioning flanges 1.
The metal sealing ring 4 is processed by red copper.
The two tensioning flanges 1 are in threaded connection with the two metal pipelines 3.
The metal sealing ring 4 is a plane metal sealing ring.
When the metal sealing ring 4 has an inclination, the contact surface of the metal pipeline 3 and the metal sealing ring 4 is processed into a corresponding angle.
The utility model has the advantages that: the utility model relates to a new to pressing seal structure, its simple structure, with low costs, not high to the installation accuracy requirement, production, construction convenience.
Drawings
FIG. 1 is a schematic view of the structure of the present invention
1. The device comprises a tensioning flange, 2 tensioning screws, 3 metal pipelines, 4 metal sealing rings and 5 sealing ring restraining rings.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1, the pressure pipeline confinement ring type counter-pressure sealing structure comprises a tensioning flange 1, a tensioning screw 2, a metal pipeline 3, a metal sealing ring 4 and a sealing ring confinement ring 5; the two tensioning flanges 1 are respectively in threaded connection with two metal pipelines 3 to be connected and sealed; firstly, a metal sealing ring 4 and a sealing ring restraint ring 5 are arranged on any one metal pipeline 3, the other metal pipeline 3 is inserted into the sealing ring restraint ring 5 and contacts the metal sealing ring 4, and two tensioning flanges 1 are tensioned through tensioning screws 2; the sealing ring restraint ring 5 is arranged between the two tensioning flanges 1 and is processed by using a metal material with high strength;
the connection method comprises the following steps:
the tensioning flange 1 is fixed on two metal pipelines 3 to be connected and sealed, a metal sealing ring 4 and a sealing ring restraint ring 5 are placed on any side of the metal pipeline 3, and the other side of the pipeline is inserted into the sealing ring restraint ring 5 to contact the metal sealing ring 4. The tensioning screw 2 is tensioned evenly. Checking whether the seal ring restraining ring 5 is radially deformed, pressed and fixed by the metal seal ring 4.
The metal sealing ring 4 is a plane metal sealing ring. When the inclined metal sealing ring is used, the contact surface of the metal pipeline and the metal sealing ring is processed into a corresponding angle
The metal sealing ring and the sealing ring restraining ring are two parts, wherein the metal sealing ring is processed by red copper or other softer metal materials, the sealing ring restraining ring is processed by metal materials with high strength, and after the sealing ring restraining ring is installed, the flange is tightened to extrude the metal sealing ring to deform and the sealing ring restraining ring are combined together to play a sealing role together.
