Problems solved by technology

In terms of welding, it is divided into butt welding head and socket welding head, which are used in various pressure vessel equipment. The market has wide application and great effect. Almost none of the pressure vessel heads circulating in the market has a certain cushioning performance. , when the head of the pressure vessel collides or rubs against foreign objects, it will directly cause quality damage to the surface of the head, affecting its performance, serious direct deformation, scrapping, increasing the cost of use, and shortening the use of the head cycle, therefore, it is necessary to design a pressure vessel head with a buffer function

Abstract

The invention relates to a pressure vessel head with a buffering function and a buffering method thereof. The buffering method comprises the following steps: sandblasting, cleaning and dedusting, drying, smearing, vulcanizing and bonding to obtain a finished product, and the styrene butadiene rubber is prepared from the following components in percentage by mass: 10-15% of butadiene, 21-25% of styrene and 6-9% of a bonding agent. According to the buffering method, the anti-buffering performance of the pressure vessel head is effectively enhanced, the effect is remarkable, the quality of the pressure vessel head is protected, the service cycle is prolonged, the cost is saved, the production and machining economic benefits of enterprises are improved, and meanwhile, the market application field of the pressure vessel head is expanded.

Description

technical field [0001] The invention belongs to the technical field of pressure vessel heads, and in particular relates to a pressure vessel head with buffer function and a buffer method thereof. Background technique [0002] The head refers to the component used to close the end of the container to isolate the internal and external media, also known as the end cap. The head of the cylindrical container is generally a rotary shell. According to the shape of the head surface, it can be divided into convex shape, conical shape, flat shape and combined shape. Convex heads refer to heads whose outer surface is convex, such as hemispherical, elliptical, dish-shaped and non-frilled spherical heads. Some gas cylinders use a combined bottom head with a convex face inward, which can not only ensure strength, but also meet the needs of safe use. The head is a part of the pressure vessel and is connected to the pressure vessel cylinder by welding. According to different geometric sh...
