Problems solved by technology
In some test occasions, the high-speed piston rod is required to complete the impact or impact. The traditional cylinder cannot achieve fast inflation due to the small cross-sectional area of the air inlet and the low response speed of the large-diameter valve to achieve high-speed piston rod.

Embodiment Construction
[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0014] Such as figure 1 As shown, the high-speed cylinder includes an air chamber 2 and a guide cylinder 1. The guide cylinder and the air chamber need to be connected reliably. The intake end of the guide cylinder 1 is inserted into the air chamber from the side of the air chamber 2 and forms a sealed and fixed structure with the air chamber. On the fixed surface of cylinder 1 and air chamber 2, a hole is opened to install the first air intake pipe that can directly input gas into the guide cylinder. On the first air intake pipe, a check valve 7 and an intake valve 6 are installed. The check valve...

The invention discloses a high-speed air cylinder. The high-speed air cylinder comprises an air chamber and a guide cylinder, wherein the air chamber and the guide cylinder are assembled into a cylinder body, an air inlet end of the guide cylinder is inserted into the air chamber from the side face of the air chamber and forms a sealing and fixing structure with the air chamber, the sealing and fixing structure is the same as a first air inlet pipeline and a second air inlet pipeline, air is directly conveyed to the guide cylinder and the air chamber, a one-way valve and an air inlet valve areinstalled on the first air inlet pipeline, the one-way valve is located between the air outdoor wall and the air inlet valve, and an air inlet valve is arranged on the second air inlet pipeline; a piston rod is arranged in the guide cylinder, and a gap is formed between the piston rod and the guide cylinder; and an air gap is formed in a part, located in the air chamber, of the guide cylinder, and sealing parts are arranged on the inner walls of the guide cylinders at the two ends of a ventilation gap respectively, so that when the piston rod is located in the position of the ventilation gap,an airtight seal is formed among the air chamber, the guide cylinder and the piston rod. The device can effectively achieve high-speed movement of the piston rod.
Description
technical field [0001] The invention relates to the field of hydropneumatics, and more specifically, the invention relates to a high-speed cylinder. Background technique [0002] The speed of the piston rod in the traditional cylinder is relatively low, generally below 5m / s. In some test occasions, a high-speed piston rod is required to complete the impact or impact. The traditional cylinder cannot achieve fast inflation to achieve high speed of the piston rod due to the small cross-sectional area of the air inlet and the low response speed of the large-diameter valve. Contents of the invention [0003] The invention proposes a high-speed cylinder, which can easily realize the high-speed movement of the piston rod, and then complete the high-speed impact to complete the extreme test. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A high-speed cylinder, including an air chamber and a guide cylinder, the inl...
