Abstract
The utility model discloses a safe air valve adjusting device which comprises an adjusting seat head and an adjusting piece. The adjusting piece comprises a horizontally-arranged first connection section, a longitudinally-arranged second connection section and a horizontally-arranged third connection section, wherein a rotatable and detachable limiting piece is positioned on the third connection section. The safe air valve adjusting device uses the adjusting piece formed by three connection sections and the limiting piece arranged at the bottom of the adjusting piece. When a user rotates the adjusting piece, the preset maximum stroke of the adjusting piece can be limited by the limiting piece, and the adjusting piece cannot rotate continuously. Thus, the adjusting piece is prevented from being excessively adjusted by an inexperienced user to shorten the service life. In addition, limiting screws are arranged at two ends of the limiting piece, so that the limiting piece can be firmly fixed and prevented from moving or loosening. The safe air valve adjusting device is reasonable in structure, convenient to transform and capable of prolonging the service life of an air valve.
Description
Technical Field
The utility model relates to a heat energy device, more exactly, be a safe pneumatic valve adjusting device.
Background
In an urban heating system, in order to ensure the steam pressure of each branch, the air valves on the branches need to be manually adjusted. The existing adjusting device is a simple adjusting cross rod, and an inexperienced user can easily adjust the air valve excessively in the using process, so that the valve core of the air valve is damaged, and local air leakage and heat leakage are caused.
Disclosure of Invention
The utility model discloses solve the technical problem that prior art exists to a safe pneumatic valve adjusting device is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides a safe pneumatic valve adjusting device, safe pneumatic valve adjusting device contain one and adjust seat head and adjustment sheet, the adjustment sheet contain a first linkage segment that transversely sets up, a vertical second linkage segment that sets up and a horizontal third linkage segment that sets up, the third linkage segment on be equipped with a rotatable and spacing piece of detachable.
As the embodiment of the utility model discloses the preferred, spacing piece contain a spacing main part, the both sides of spacing main part be equipped with the wing of bending of a downwarping respectively, the middle part of spacing main part be equipped with a first fixing hole, the wing of bending on be equipped with a second fixing hole respectively, a connecting screw runs through first fixing hole and with third linkage segment fixed connection, the second fixing hole in be equipped with a limiting screw respectively.
The utility model discloses a safe pneumatic valve adjusting device utilizes the spacing piece of adjustment sheet and adjustment sheet bottom that the three-section is connected, and when the user rotated the adjustment sheet, its maximum stroke of predetermineeing received spacing and can not continue to rotate of piece, just so prevent that the user that experience lacks excessively and lead to the pneumatic valve life-span to reduce with the pneumatic valve regulation. In addition, because the two ends of the limiting sheet are provided with the limiting screws, the limiting sheet can be firmly fixed to prevent the limiting sheet from moving or loosening. The safety air valve adjusting device is reasonable in structure and convenient to transform, and the service life of the air valve is prolonged.
