Embodiment 1

[0022] Embodiment 1: as figure 1 As shown, the valve stem thread derusting device includes a rotating disk 1; a rotating shaft 2, the rotating shaft is located at the center of the rotating disk; a derusting line 3, the sleeve removal line is wound on the rotating shaft; a valve stem placement hole 4, the valve stem is placed The hole is opened on the turntable; the valve stem clamping mechanism 5, the valve stem clamping mechanism is located above the valve stem placement hole; the driving mechanism 6, the driving mechanism drives the valve stem clamping mechanism to move up and down; the anchor column 7, the Anchor posts are located on the edge of the turntable to fix the free ends of the descaling lines.

[0023] The turntable can be driven by an external drive mechanism, or directly pushed by hand. The turntable rotates while the rotating shaft is stationary, the bottom of the rotating shaft can be fixedly connected on a base, and the derusting wire can be a flexible wiri...

Embodiment 2

[0024] Embodiment 2: The difference with Embodiment 1 is that, as figure 2 As shown, the drive mechanism includes a left cylinder and a right cylinder, the top of the piston rod of the left cylinder is affixed to the bottom of the left half hoop, the top of the piston rod of the right cylinder is affixed to the bottom of the right half hoop, and the The left and right cylinders are synchronously controlled by PLC.

[0025] Such as image 3 As shown, the method of using the valve stem thread derusting device includes the following steps: (1) Insert one end of the polished valve stem to be derusted into the valve stem placement hole, with the threaded section of the valve stem facing upwards, and the valve stem clamping mechanism Clamp the valve stem, lead the free end of the derusting line from the rotating shaft to the top circle of threads of the threaded section of the valve stem and fix it on the anchor column; (2), turn the turntable clockwise, and the valve stem is clam...

Abstract

The invention discloses a valve rod thread rust removal device and a using method thereof. The valve rod thread rust removal device comprises a rotating disc (1). The rotating shaft (2) is positioned in the center of the turntable; the sleeve removing line (3) is wound on the rotating shaft; the valve rod placing hole (4) is formed in the turntable; the valve rod clamping mechanism (5) is positioned above the valve rod placing hole; the driving mechanism (6) drives the valve rod clamping mechanism to move up and down; the anchor columns (7) are located on the edge of the rotary disc and used for fixing the free ends of the rust removal lines. The valve rod thread rust removal device has the beneficial effects that the automatic or semi-automatic valve rod thread rust removal device is designed, the rust removal line is driven to be wound on the surface of a valve rod thread through relative movement of the rotating disc and the rotating shaft, the rust removal line does not damage the thread, the labor intensity is reduced, the rust removal speed is increased, and the thread is prevented from being damaged.

Description

technical field [0001] The invention relates to the field of maintenance of valve fittings, in particular to a valve stem thread derusting device and a use method thereof. Background technique [0002] The valve stem is the part of the valve used to connect the handwheel and the valve core. When the handwheel is turned, it is used to transmit torque, drive the valve core to rotate, close or open the sealing port, and control the fluid in the valve body. [0003] The valve stem, especially the threaded part, should be cleaned frequently and new lubricant added to prevent hard debris in the dust from wearing the thread and the surface of the valve stem, which will affect the service life. For valves that have been left unused for a long time, special attention should be paid to cleaning the threaded part of the valve stem. However, in the existing cleaning methods, cleaning tools such as wire brushes, scrapers, and sandpaper should be used when necessary in order to better rem...
