Description

[0002] With the extension of human activity range to the deep sea region, people have higher and higher functional requirements for ships, and more and more valve groups need to be arranged on ships. Due to the limited space of ships, valve groups gradually develop in the direction of integration. The integrated valve group has the following advantages: saving space, simplifying the installation process, improving reliability, facilitating maintenance, reducing leakage risk, etc. However, the integration of valve groups greatly increases the installation difficulty of valve groups.

[0003] As shown in Figure 1 , Figure 2 , a commonly used valve group connecting piece on a ship includes a first flange 11, a second flange 12 and a third flange 13. The inner hole of the first flange 11 is provided with a first flange connector 111, the inner hole of the second flange 12 is provided with a second flange connector 121, and the inner hole of the third flange 13 is provided with a third flange connector 131. The first flange connector 111 is connected to the first branch pipe of a tee joint 15 through an elbow pipe 14, the second branch pipe of the tee joint 15 is connected to the second flange connector 121, and the third branch pipe of the tee joint 15 is connected to the third flange connector 131. The first flange 11, the second flange 12 and the third flange 13 are respectively connected to valves, so that three valves can be integrated into a valve group. The first flange 11 is used to connect branch pipe valves, and the second flange 12 and the third flange 13 are used to connect two main pipe valves. To ensure the relative position of the three valves, the flatness of the flange face A1 of the first flange 11, the flange face A2 of the second flange 12 and the flange face A3 of the third flange 13 and the perpendicularity to the main pipe must meet the requirements.

[0004] The assembly method of the valve group connecting piece is as follows: first, connect the first flange connector 111 to the first flange 11 by threading, connect the second flange connector 121 to the second flange 12 by threading, and connect the third flange connector 131 to the third flange 13 by threading; then weld one end of the elbow pipe 14 to the first flange connector 111 (first welding point B1), weld the other end of the elbow pipe 14 to the first branch pipe of the tee joint 15 (second welding point B2), weld the second branch pipe of the tee joint 15 to the second flange connector 121 (third welding point B3), and weld the third branch pipe of the tee joint 15 to the third flange connector 131 (fourth welding point B4).

[0005] Due to the existence of multiple welding points, high-temperature welding deformation can cause the flatness of the flange face A1 of the first flange 11, the flange face A2 of the second flange 12 and the flange face A3 of the third flange 13 and the perpendicularity to the main pipe to be obviously out of requirements after assembly, and therefore post-welding treatment needs to be performed on the assembled valve group connector, and at present, the post-welding treatment can only rely on manual positioning, which greatly reduces the work efficiency and greatly increases the production cost of the valve group.
