2) the composite material gas cylinder is light in weight, is suitable for being applied to the field of aerospace, and has the problems of high cost, incompatibility with liquid oxygen and the like;
3) the traditional spherical and cylindrical gas cylinders are difficult to be made into large volumes, the volume is generally not more than 500L and is usually about 100L, so that more valves and pipelines are required to be installed in many application scenes, and the complexity and the weight of the system are increased;
4) the traditional spherical and cylindrical gas cylinders occupy large space and are inconvenient to install in the aircraft.
The invention patent 202110242791.9 discloses a structural form of intersecting spherical shell pressure vessel with high structural efficiency; the invention patent 202210049625.1 discloses a structural form of a fiber winding intersecting spherical shell pressure vessel on the basis of the former; the invention patent 202210251667.3 discloses a bulging manufacturing method of the two inventions. The three patents are mostly applied to the pressure vessel with the similar cylindrical structure, and do not provide a comprehensive solution for the annular pressure vessel and solve the design problems of the air inlet and outlet design, the liquid oxygen compatibility design, the manufacturing method and the like.
Based on the 3 patents, the invention discloses a fiber ring reinforced intersected spherical shell ring pipe gas cylinder structure scheme with a protective sleeve and a manufacturing method thereof, based on the characteristics and special design requirements of a ring pipe pressure container structure, and particularly aiming at the application requirements of low cost, large volume, liquid oxygen compatibility, convenience in installation and the like.
Disclosure of Invention
The invention mainly solves the difficult problems of designing and manufacturing a pressure container which has large volume, light weight, low temperature resistance, compatibility with liquid oxygen, space saving and low cost, and discloses a fiber ring reinforced intersected spherical shell ring pipe gas cylinder structure scheme with a protective sleeve and a manufacturing method thereof.
The beneficial effects of the invention are:
1) the volume is large, and 1 cubic meter or even larger volume can be easily realized;
2) the weight is light, and the structural efficiency equivalent to that of a composite gas cylinder can be realized by using a small amount of composite material for reinforcement;
3) the liquid oxygen is compatible, and the composite material is completely coated by the protective material and cannot be contacted with the liquid oxygen;
4) the installation is convenient, and the annular belt reinforcing ring structure can be very conveniently installed inside the rocket storage tank or inside the cylindrical tank section and the cylindrical stage section;
5) the cost is low, the preferred material is low-cost stainless steel and aluminum alloy, the using amount of the composite material only accounts for about 20 percent of the total weight, the composite material is a simple winding structure, and the whole manufacturing process of the product does not need complex and expensive dies or tools;
6) high reliability, less welding seams and high reliability by using spinning seamless steel tube for welding.
The invention discloses a circular pipe gas cylinder, which comprises the following structural components and is manufactured by the following processes:
1) the ring pipe gas cylinder consists of a metal ring pipe, a composite material reinforcing ring, a reinforcing ring protective sleeve and an air inlet and outlet hole;
2) the metal ring pipe is a thin-wall metal tire-shaped pipe, and an intersected spherical shell ring pipe structure is formed by internal pressure bulging under the constraint of a composite material reinforcing ring. The metal ring pipe is preferably made of stainless steel, aluminum alloy or high-temperature alloy which has good plasticity and is easy to cold work and harden, is preferably welded after being bent based on spinning seamless pipe, and is finally formed by internal pressure bulging;
3) the composite material reinforcing ring is a composite material unidirectional winding ring, the number, the inner diameter and the cross section shape of the composite material reinforcing ring are optimized by taking the maximum stress minimization of the metal ring pipe as a target, the circumferential distance is 50 to 70 percent of the radius of the cross section of the metal pipe before expansion, and the total weight of the composite material is about 20 percent of the total weight of a ring pipe finished product. The composite material is preferably a low-temperature-resistant high-rigidity and high-strength carbon fiber composite material; the inner diameter of the composite material reinforcing ring is slightly larger than the outer diameter of the ring pipe before bulging, so that the composite material reinforcing ring can be conveniently sleeved outside the ring pipe and then bulged and fixed;
4) when the composite material reinforcing ring is applied to an environment where liquid oxygen is not suitable for composite material exposure, a thin-wall protective layer is coated on the outer surface of the composite material reinforcing ring, and a thin metal plate is preferably welded and sealed, so that special requirements such as liquid oxygen compatibility are met;
5) the composite material reinforcing rings are uniformly and equidistantly sleeved outside the metal ring pipe before bulging, and the reinforcing rings are respectively arranged on two sides of the air inlet and outlet hole to ensure the strength near the air inlet and outlet hole;
6) the maximum pressure during bulging forming meets the requirements of strength and toughness of the material, and the composite material reinforcing ring can be completely clamped;

The intersecting spherical shell shaped metal grommet according to claim 1, characterized in that: firstly, the bulging front ring pipe is an axisymmetric ideal tire ring pipe, and the outer diameter of the bulging front ring pipe is smaller than the inner diameter of the composite material reinforcing ring; the ring pipe is preferably made of metal materials with good plasticity and high cold hardening efficiency, including but not limited to stainless steel, aluminum alloy, high-temperature alloy and the like; thirdly, when the material is applied to a liquid oxygen environment, the material is selected from austenitic stainless steel, nickel-based high-temperature alloy, aluminum alloy and the like which are compatible with liquid oxygen and have low temperature resistance; the circular pipe is formed by welding a plurality of bent pipes, so that the number of welding seams is reduced, and the number of the bent pipes is as small as possible; the elbow is preferably bent based on a spinning seamless metal pipe. Sixthly, the expanded ring pipe is in a shape of an annular intersected spherical shell, and a spherical shell intersection line is arranged at each composite material reinforcing ring.
4. The composite reinforcement ring of claim 1, wherein: firstly, the composite material reinforcing ring is in a unidirectional fiber composite material winding structure; secondly, when the paint is applied to ultralow temperature environments such as liquid oxygen and the like, a low-temperature resistant resin material needs to be selected; the inner diameter, the cross section shape and the number of the composite material reinforcing rings are optimally designed by the aim of minimizing the maximum stress of the metal ring pipe under the designed internal pressure; and fourthly, reinforcing rings are respectively arranged at the two sides of the gas inlet and the gas outlet of the gas cylinder and are close to the gas inlet and the gas outlet, so that the structural strength near the gas inlet and the gas outlet can be improved.
5. A reinforcing ring boot as claimed in claim 1, wherein: firstly, the reinforcing ring protective sleeve completely wraps the composite material reinforcing ring, so that the effect of isolating the external environment is achieved; only when the composite material reinforcing ring is applied to an environment which cannot be adapted to, the reinforcing ring protective sleeve needs to be used, for example, the reinforcing ring protective sleeve is soaked in liquid oxygen; and thirdly, the reinforcing ring protective sleeve is preferably manufactured by welding thin metal plates adaptive to the external environment.
