Description

Technical Field

[0002] Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, and mainly play a cutting and throttling role in pipelines.

[0003] During the assembly process of the butterfly valve, a sleeve is arranged between the valve shaft and the two flange heads to support the rotation of the valve shaft. The sleeve plays a role similar to a bearing. The sleeve assembly method is divided into manual assembly and hydraulic assembly. Manual assembly uses a hammer or other tool to knock the sleeve into the flange head, and hydraulic assembly uses a hydraulic press to press the sleeve into the flange head. Manual assembly has low cost, but is time-consuming and inefficient, and there are certain safety hazards in the operation. The existing hydraulic assembly (such as a sleeve installation device disclosed in application number 201821372053.6) can only assemble one sleeve at a time, and there is also a problem of low efficiency. In addition, the two sleeves are installed in different positions and enter the corresponding two flange heads from two different directions. The direction of the valve body needs to be adjusted back and forth, which is complicated to operate and prone to missing installation. Utility Model Content

At this time, the blocking member 510 can block the valve body 110 moving to the pressing station 210, and the two flange heads 120 are coaxial with the two positioning shafts 310. The first telescopic driving member 424 is manipulated so that the first telescopic driving member 424 can drive the corresponding installation rod 421 to approach the press-fitting station 210. At this time, due to the transmission effect of the corresponding connecting rod 423, the rotating rod 422 is driven to rotate, and then through the transmission effect of another connecting rod 423, the other installation rod 421 can be driven to approach the press-fitting station 210 synchronously, so that both of the two sleeves 410 can approach the press-fitting station 210, and the corresponding sleeve 130 is pushed onto the positioning shaft 310 through the sleeve 410. The two sleeves 130 are pressed into the corresponding flange heads 120 by sliding. When the two sleeves 130 are pressed into the corresponding flange heads 120, the first telescopic driving member 424 is used to drive the corresponding mounting rod 421 away from the press-fitting station 210, and the other mounting rod 421 is synchronously moved away from the press-fitting station 210 through the transmission action of the two connecting rods 423 and the rotating rod 422, so that the two sleeves 410 can be moved away from the press-fitting station 210, and the two sleeves 410 are moved away from the press-fitting station 210. The other end is moved out from the corresponding flange head 120 to prepare for the next press-fitting of the sleeve 130.
