Problems solved by technology
After the flange is welded, it is very easy to cause deformation of the flange mounting surface and cause seal leakage. At the same time, there is welding stress between the oil pipe and the flange, and it is easy to cause cracks at the weld when used under high pressure for a long time.
It is also difficult to install the hard pipes at both ends due to heat deformation after welding, which may easily cause leakage at the flange connection

Embodiment Construction
[0018] Such as Figure 1-3 As shown, an axially movable high-pressure intermediate connecting flange structure connects the oil pipe on the left pipeline and the oil pipeline on the right pipeline. It includes a cylindrical flange body 01, a left end cover 02, a right end cover 03, a left connecting rod 04 and The right connecting rod 05; the flange body 01 is a pressure-resistant body, and the two sides of the central cavity of the flange body 01 are respectively provided with a left connecting rod 04 and a right connecting rod 05, and the left connecting rod 04 and the right connecting rod 05 are respectively It is in movable sealing contact with the flange body 01. The left connecting rod 04 and the right connecting rod 05 protrude from both ends of the flange body 01 respectively, and there is a gap between the left connecting rod 04 and the right connecting rod 05. The movable gap 06 of the flange is respectively provided with limit steps on the left side of the left conn...

The invention relates to an axially movable high-pressure intermediate connection flange structure and its use method, which includes a cylindrical flange body, a left end cover, a right end cover, a left connecting rod and a right connecting rod; There are left connecting rods and right connecting rods respectively arranged on both sides. The left connecting rods and right connecting rods are respectively in movable sealing contact with the flange body. There is a gap between the left connecting rod and the right connecting rod, and limit steps are respectively set on the left side of the left connecting rod and the right side of the right connecting rod, and the left end cover and the right end cover are set on the left connecting rod and the right connecting rod , the left end cover and the right end cover are fixedly connected to the flange body by a number of connecting screws respectively, and the left end cover and the right end cover are respectively pressed on the limit steps on the left connecting rod and the right connecting rod. The design is reasonable, the structure is simple, the installation is convenient, and there is no oil leakage; the influence of welding stress on flange installation is avoided, and the influence of hydraulic vibration on pipelines is reduced or eliminated, and welding pipelines will not cause thermal deformation of flange planes.
Description
technical field [0001] The invention relates to the field of connecting flanges, in particular to an axially movable high-pressure intermediate connecting flange structure and a use method thereof. Background technique [0002] Generally, the traditional hydraulic connection intermediate flange adopts the rigid pipe fixed welding structure. After the flange is welded, it is very easy to cause deformation of the flange mounting surface and cause seal leakage. At the same time, there is welding stress between the oil pipe and the flange, and it is easy to cause cracks at the weld when used under high pressure for a long time. It is also difficult to install the hard pipes at both ends due to thermal deformation after welding, which may easily cause leakage at the flange connection. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an axially movable high-pressure intermediate connection flange structure and its use metho...
