Embodiment Construction

[0019] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the present invention provides a breakable cover stop structure suitable for high-pressure gas ejection test equipment, the structure includes a lower flange 1, an upper flange 2, a stop structure body 3, a stop rod 4, and reinforcing ribs 5. The stop structure body 3 is a cylindrical structure with openings at both ends. The lower flange 1 is arranged on the lower end, the upper flange 2 is arranged on the upper end, and the middle part is fixedly connected with the stop rod 4, and the stop The rod 4 is located on the inner wall surface of the stop structure body 3; the stop rod 4 is used to collide with the frangible cover body after the frangible cover body flies out a certain dista...

Abstract

The invention relates to a breakable cover stop structure suitable for a high-pressure gas ejection test device, which belongs to the technical field of launching. The invention provides a breakable cover stopping structure suitable for a high-pressure gas ejection test device. The scheme is simple in structure and reliable in operation, and can effectively stop the flying breakable cover body and prevent the structure of the breakable cover body from being hit or even damaged The object to be ejected; the windward side of the stop rod is designed with low resistance, which effectively stops the body of the fragile cover and does not hinder the smooth flow of high-pressure gas in the stop structure.

Description

technical field [0001] The invention belongs to the technical field of launch, and in particular relates to a stop structure for a fragile cover suitable for a high-pressure gas ejection test device. Background technique [0002] In the high-pressure gas ejection test device, after the high-pressure gas storage chamber is inflated by an external air source, the pressure of the high-pressure gas storage chamber increases, and when a certain pressure value is reached, the fragile cover between the high-pressure gas storage chamber and the low-pressure chamber is automatically broken. The high-pressure gas is released into the low-pressure chamber, and the moving object moves under the action of the high-pressure gas, so as to achieve the purpose of giving the ejected object a certain speed. After the fragile cover is broken, its body structure will move upward at high speed under the action of high-pressure gas, which may hit the ejected object or even cause damage to the ejec...
