Embodiment 1

[0016] When using this embodiment, the seat ring of the thrust ball bearing, the steel ball cage assembly and the shaft ring are stacked in sequence and clamped on the positioning block 9, and the horizontal positioning plate 6 is horizontally placed on the port of the valve seat. The vertical rod 8 and the bearing are located in the mounting hole of the valve stem. After the horizontal positioning plate 6 is fixed, the vertical screw 2 is rotated with a tool, and the horizontal connecting plate 4 moves downward under the drive of the vertical screw 2, thereby slowly leveling the bearing. Put down and move, after the bearing is pressed well, the vertical screw 2 drives the horizontal connecting plate 4 to move up to take out the vertical rod 8, and the bearing installation is completed; the present embodiment can quickly install the bearing through the above structure, and the installation When the bearing is always level, there will be no inclination, the installation is quick...

Embodiment 2

[0019] In this embodiment, in order to facilitate the fixing of the horizontal positioning plate 6, reduce the difficulty of tool fixing, and avoid the trouble of installing the fixing device, both ends of the horizontal positioning plate 6 are bent to form a bayonet 7, which is clamped on the upper end of the valve through the bayonet 7. The horizontal positioning plate 6 can be firmly fixed on the flange plate and locked by the lock nut, which is convenient for bearing installation.

[0020] Example 3

Embodiment 3

[0022] In this embodiment, the lower end of the positioning block 9 has an L-shaped structure, and the gaps of the L-shaped structures of the two positioning blocks 9 are reversely arranged. When positioning, one side of the L-shaped structure of the bearing is located at the upper end of the bearing, and the other side is located at the inner circumference of the bearing. Clamp and position the bearing to keep it horizontal, and the bearing can be pressed tightly, so that the fixing and positioning effects are good.

Abstract

The invention discloses a simple tool for mounting a valve bearing. The simple tool comprises a horizontal positioning plate (6), a vertical threaded rod (2) and a lifting device, wherein the lifting device comprises a horizontal connecting plate (4) and vertical rods (8) at the two ends of the horizontal connecting plate (4); a positioning groove (3) is formed in the middle part of the horizontal positioning plate (6); the vertical threaded rod (2) is in threaded connection with the middle part of the horizontal connecting plate (4), and penetrates through the rear lower end of the middle part of the horizontal connecting plate (4) to be positioned in the positioning groove (3); the vertical rods (8) penetrate through the horizontal positioning plate (6); positioning blocks (9) are connected to the lower ends of the vertical rods (8). The simple tool for mounting the valve bearing is convenient to use, a bearing can be horizontally mounted well and protected well, the problem of damage to the bearing which is knocked can be solved, high mounting speed and mounting reliability are ensured, and the practicability is greatly improved.

Description

technical field [0001] The invention relates to a petroleum valve assembly tool, which belongs to the field of petroleum, and more specifically relates to a simple tool for installing valve bearings. Background technique [0002] Some petroleum valves need to fill thrust ball bearings inside the valve seat before installing the valve stem to reduce the movement friction of the valve stem. When installing the thrust ball bearing, put the seat ring of the thrust ball bearing, the steel ball cage assembly and the shaft ring into the valve stem mounting hole in sequence, and then hit the upper end of the shaft ring with a heavy object to seal the three parts. However, since the seat ring, steel ball cage assembly and shaft ring are prone to inclination when placed, the three are easily stuck in the hole when knocked, and the bearing is also easily damaged. It is necessary to adjust the seat ring, steel ball cage assembly and shaft ring every time before knocking. Not only the i...
