[0012] Markings in the figure: 1 is the bracket, 2 is the smooth hole, 3 is the adjusting screw, 4 is the fixing nut, 5 is the lifting and lowering adjusting nut, 6 is the U-shaped clamp, 7 is the first clamping bolt, 8 is the second clamping bolt, 9 is the valve body, 10 is the valve cover, 11 is the valve cover screw hole, 12 is the valve body screw hole, and 13 is the gasket. DETAILED DESCRIPTION
[0013] As shown in the accompanying drawings, the present embodiment provides a steam trap maintenance auxiliary device, including a bracket 1, a light hole 2 is arranged in the middle of the bracket 1, an adjusting screw 3 is arranged through the light hole 2, a clamping claw is threadedly connected below the adjusting screw 3, and the adjusting screw 3 is threadedly connected to the clamping claw and then fixed by a fixing nut 4 on the adjusting screw 3, and a lifting and lowering adjustment nut 5 is threadedly connected to the adjusting screw 3 above the bracket 1, and the lifting and lowering adjustment nut 5 is axially limited by the upper surface of the bracket 1.
[0014] The clamping jaw includes a U-shaped clamp 6, a first clamping bolt 7 and a second clamping bolt 8. The U-shaped clamp 6 is opened downward, and a threaded hole matching the adjusting screw 3 is arranged on the transverse plane of the U-shaped clamp 6. The first clamping bolt 7 and the second clamping bolt 8 are respectively threadedly connected to the two opposite vertical surfaces of the U-shaped clamp 6.
[0015] Here’s how to use it:
[0016] Place the bracket 1 securely above the inspection position of the steam trap valve body 9, unscrew the lifting and lowering adjustment nut 5, lower the adjusting screw 3 and the clamping jaws to the position of the valve cover 10, clamp the valve cover 10 of the steam trap with the U-shaped clamp 6 of the clamping jaws, adjust the center of gravity of the valve cover 10, and clamp the outer end of the valve cover 10 by adjusting the first clamping bolt 7 and the second clamping bolt 8.
[0017] The valve cover 10 is adjusted by rotating the lifting adjustment nut 5 to drive the adjusting screw 3 to rise and fall, and the position between the valve cover screw hole 11 of the steam trap and the valve body screw hole 12 of the steam trap is adjusted to ensure that the valve cover 10 falls toward the steam trap valve body 9, while avoiding the problem that the state of the gasket 13 cannot be observed in the traditional manual operation, ensuring that the gasket 13 can be located between the valve cover 10 and the steam trap valve body 9 without abnormality, and avoiding damage to the gasket 13 to affect the sealing of the steam trap.
