DE1054800B - Short gate valve - Google Patents

Description

According to the prior art flangeless shut-off devices are known, which between the flanges of the Pipes are clamped. However, these can only be used for small pipe sizes.

The inventor has set himself the goal of creating a new construction that, regardless of the Number of screws is suitable for all nominal sizes.

To clamp the gate valve between the pipe flanges, U- shaped brackets are used that overlap the pipe flanges and pressure screws are provided in the flange parts with which the pipe flanges are pressed tightly against the end wall of the housing of the gate valve.

If you now loosen the pressure screw a little, you can turn the slide around the pipe axis around any desired Pivot the angle and fix it at the most favorable angle. This setting is particularly common in underground mining very welcome.

The upper clamp is expediently made by an all-round weld seam or by casting on connected to the lock housing in the case of cast constructions. When loosening all screws can the lock housing can be easily pulled out with the clamp that is firmly attached to it. Can do anything can be checked and cleaned quickly and easily. If it's just cleaning, you can remove the lower clamp and open the designated dirt hatches and then again conclude. Here, too, it is important that the locking device can be pivoted around its pipe axis, so that dirt hatches that are difficult to access can also be cleaned well.

It is possible to have one or more continuous brackets, especially on the two lower clamps Pull in screws to fix it, which is particularly useful during assembly, in order to ensure a permanent or to provide temporary reliable support. So you can make holes for through screws in place the lower sections between two pressure screws. Particularly suitable for continuous Screws are the kerfs of the tensioning clamps, then in the existing kerfs of the pitch circle appropriate holes are required.
