Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as figure 1 As shown, the finely ground stainless steel pressure-resistant hollow float is mainly composed of an upper hemisphere (1), a vent hole (2), a centerline weld (3) and a lower hemisphere (4). Firstly, design a semi-spherical drawing die, and stretch the stainless steel plate into two semi-spherical semi-sphericals with equal wall thickness through a numerical control hydraulic stretching machine, namely the upper hemisphere (1) and the lower hemisphere (4); trim the edges according to the design parameters , a 1.5mm vent hole (2) is drilled on the top of the upper hemisphere (1), so that the hollow ball maintains the balance of internal and external pressure during welding; the upper hemisphere (1) and the lower hemisphere (4) are connected in a triangular shape by argon shield welding The welding is fixed without leaving a gap; t...

Abstract

The invention discloses a fine grinding stainless high temperature and high pressure resistance hollow floating ball used for a pressure pipeline component. After being precisely grinded, the circular accuracy of the ball can reach 0.2 percent of the diameter of the floating ball. The hollow floating ball has the advantages that the accuracy of the floating ball is high, the sealing performance is good, and any spherical face can be taken as the sealing surface; formulary liquid is filled inside the floating ball, so that the floating ball is ensured to resist the high temperature and high pressure, the centralized abrasion can not be caused during the operating period, and the service life is long.

Description

technical field [0001] The invention relates to a metal hollow ball, in particular to a finely ground stainless steel high temperature and high pressure resistant hollow floating ball applicable to pressure pipeline components. Background technique [0002] At present, there are two main types of stainless steel hollow floats that are more common in the market: [0003] One is a stainless steel hollow float with surface polishing treatment on the hollow float. The surface of this polished hollow ball is very bright, and no welding traces can be seen, but the roundness of the float is not fine enough, similar to an ellipse shape, and the wall of the ball is very thin. light weight. This kind of polished float is generally only suitable for appliances with less strict requirements such as decorations or sanitary ware. [0004] One is a stainless steel hollow floating ball processed by the principle of a tumbler, that is, the upper and lower hemispheres with different wall th...
