Problems solved by technology

In this way, obvious knocking marks will be left on the surface of the butterfly plate 13, which will affect the appearance
The impact force produced by percussion often damages the rubber ring 15, and also produces huge noise that affects the surrounding employees, and the market price of the used rubber ring is about 2500~4000 yuan
If the rubber ring is damaged, it will be scrapped, causing economic losses
Especially for DN400~700 large-diameter butterfly valves, there are many contact surfaces between the butterfly plate and the rubber ring, which is very difficult and requires three assemblers to cooperate with each other, which is inefficient.

Embodiment Construction

[0015] based on the following figure 2 and image 3 , specifically explain the preferred embodiment of the present invention.

[0016] like figure 2 and image 3 As shown, the present invention provides a butterfly valve assembly auxiliary tool, which tool includes a beam 3, a hook bell 22 arranged at both ends of the beam, a rod bell 21 arranged on the beam, a hook 1 for connecting the hook bell 22, and a Cross bar with the bar 5 of live bell 21 and the hand wheel 6 that is connected with bar 5;

[0017] Fix with pin 4 between described hook 1 and hook live bell 22;

[0018] Also set fixture 9 on the hook live bell 22, this fixture 9 is a bolt and a washer;

[0019] Fix with bolt 8 and washer 7 between described rod 5 and handwheel 6;

[0020] Several different installation positions are reserved on the beam 3. According to the size of the valve body flange of the butterfly valve, determine the fixed position of the hook live bell 22 on the beam 3. The hook 1 hooks th...

Abstract

A butterfly valve assembly auxiliary tool comprises a beam, movable hook bells arranged at two ends of the beam, movable bells for a lever, hooks connected with the movable hook bells, the lever penetrating through the movable bells for the lever and a hand wheel connected with the lever, wherein, the movable bells for the lever are arranged on the beam. According to the butterfly valve assembly auxiliary tool, unnecessary damage of a sealing ring caused by brutal installation of a butterfly valve is avoided, labor intensity is reduced, work efficiency is improved and unnecessary economic loss is avoided.

Description

technical field [0001] The invention relates to an auxiliary tool for assembling a butterfly valve. Background technique [0002] like figure 1 As shown, the current assembly process for Korean-style central butterfly valves is: after installing the butterfly plate 13 and valve stem 12 when the butterfly valve is open, close the butterfly valve in place, and after the pump water is inspected and passed, then fix it with a conical pin 16 The butterfly plate 13 and the valve stem 12 complete the assembly of the butterfly valve body 11 . Since the butterfly plate 13 and the rubber ring 15 are interference fit, the current method is to vigorously knock the butterfly plate 13 into place with an aluminum rod. In this way, obvious knock marks will be left on the surface of the butterfly plate 13, which will affect the appearance. The impact force that knocking produces often damages rubber ring 15, also produces huge noise and affects surrounding staff, and the used rubber ring ...
