Embodiment Construction

[0008] The structure of the gas distribution ring of the ship air pressure sealing device of the present invention is as follows: figure 1 As shown, supporting beams 3 are installed between supporting plates 1, and an air inlet 2 is arranged in the middle of supporting beams 3, and supporting plates 1 and supporting beams 3 are made of nylon material. In order to make the support beam 3 better connect and support the supporting plate 1, the inner surface and the outer surface of the support beam 3 along the radial direction are all concave parabola curved surfaces, which can better eliminate the gas distribution ring itself during use. of stress. There are 6 air intake holes 2 in the radial direction on the support beam 3, and the ratio of the minimum thickness of the support beam 4 in the radial direction to the width LT of the supporting plate 1 is 1 / 8, which makes the thickness of the support beam 3 relatively thick, greatly The strength of the gas distribution ring is imp...

Abstract

The gas distribution ring of the ship's air pressure sealing device, the support beam is installed between the support beams, and the air inlet hole is arranged in the middle of the support beams, and the support plate and the support beam are made of nylon material. The gas distribution ring of the marine air pressure sealing device of the present invention adopts this structure, which simplifies the processing and process of the gas distribution ring; the use of nylon material avoids the need to prevent the high temperature deformation of the supporting plate during the welding process, causing the supporting plate to be uneven , thus affecting the use effect; the manufacturing cost is higher. And because the molding time is very short, the labor productivity is greatly improved, and the cost of the product is greatly reduced.

Description

technical field [0001] The invention relates to the field of ship equipment, in particular to a gas distribution ring for a ship air pressure sealing device. Background technique [0002] Ship air pressure seal device is a commonly used seal device for ships. It is often used together with main seal devices such as oil lubricated seal device, water lubricated seal device and mechanical seal device. It can be used for rotating shafts such as ship shafts and electric propeller shafts of marine engineering ships. The air pressure sealing device consists of an air sealing seat, a ring-shaped opening air bag made of rubber installed in the air sealing seat, a gas distribution ring embedded in the opening air bag, and the opening air bag is fixed and sealed on the air sealing seat The current gas distribution ring is made of stainless steel, including two parallel and coaxial annular supporting plates with the same shape and size. There is a gap between the middle parts of the two...
