Background technology
When spacecraft carries out Aerodynamic Heating protection test, experimental enviroment Jing is often filled with high-temperature gas, the piston gas commonly used at present
Cylinder long-time cisco unity malfunction in the hot environment, the rigid support with water-cooled can for a long time in hot environment but not
Can move back and forth, therefore be badly in need of a kind of water-cooled cylinder of the long-time of design in hot environment.
The content of the invention
The technology solve problem of the present invention：Overcome the deficiencies in the prior art, there is provided a kind of water-cooled cylinder, can be prolonged
Run in 500 DEG C of hot environments, meet spacecraft Aerodynamic Heating protection test requirement.
Technical scheme：A kind of water-cooled cylinder, including cylinder body, piston, front end housing and back cylinder cover；
Piston is located in cylinder body cavity, and front end housing and back cylinder cover are located at cylinder body two ends, and the piston rod of piston passes through front cylinder
Cover and be connected with the part of outside need activity, in the side wall of cylinder body and in front end housing water-cooling channel and gas passage are machined with,
Water inlet, outlet, air inlet and gas outlet, wherein water inlet and outlet and the water in cylinder side wall are machined with back cylinder cover
Cold passage is connected, and air inlet is connected with cylinder body cavity, and gas outlet is connected with gas passage.
The water-cooling channel has two, and the water-cooling channel in cylinder side wall is uniformly distributed along cylinder side wall, a diameter of
The 1/2 of cylinder side wall wall thickness.
The 1/3 of a diameter of front end housing thickness of water-cooling channel in front end housing.
Present invention advantage compared with prior art is as follows：
(1) present invention in cylinder side wall and machined water-cooling channel in front end housing, and cooling water enters water-cooled from water inlet
In cylinder body and front end housing, then go out from outlet, so circulation, water-cooled cylinder has been effectively ensured can be for a long time in hot environment
Work.
(2) present invention achieves water cooling cylinder supply can simultaneously be supplied water and supplied, while water-cooling channel for water integrated
It is separate with gas passage, it is independent of each other.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, water-cooled cylinder of the invention, including cylinder body 1, piston 2, front end housing 3 and back cylinder cover 4.
Piston 2 is located in the cavity of cylinder body 1, and front end housing 3 and back cylinder cover 4 are located at the two ends of cylinder body 1, and the piston rod of piston 2 passes through front end housing 3
It is connected with the part of outside need activity.I.e. the front end of piston 2 is sealed by front end housing 3, and rear end is sealed by back cylinder cover 4.
As shown in Fig. 2, Fig. 4 and Fig. 6, gas passage 12, back cylinder cover 4 are machined with the side wall of cylinder body 1 and in front end housing 3
On be machined with air inlet 43 and gas outlet 44, wherein air inlet 43 is connected with the cavity of cylinder body 1, gas outlet 44 pass through gas passage 12
It is connected with the cavity of cylinder body 1, for controlling the motion of piston 2.
As shown in Figure 3, Figure 5 and Figure 6, water-cooling channel 11, back cylinder cover 4 are machined with the side wall of cylinder body 1 and in front end housing 3
On be machined with water inlet 41 and outlet 42, wherein water inlet 41 is connected by water-cooling channel in cylinder body 1 with the water-cooling channel of front end housing 3
Logical, outlet 42 is connected by water-cooling channel 11 in cylinder body 1 with the water-cooling channel of front end housing 3, for cooling down to cylinder.
As shown in figure 5, in front end housing 3 a diameter of thickness of front end housing 3 of water-cooling channel 1/3.Cylinder body 1 is located at as shown in Figure 6
Water-cooling channel 11 in the wall of side is uniformly distributed along cylinder side wall, and the 1/2 of the side wall wall thickness of a diameter of cylinder body 1.
Water cooling cylinder of the present invention is provided with water-cooling channel and gas passage, can simultaneously supply water and supply, by cooling water
Recycling-guard cylinder body and in front and back cylinder cap, by controlling gas passage air inlet or aerofluxuss promotion piston or retracting piston.
Specifically, cooling water is entered by back cylinder cover water inlet 41, before being reached by the water-cooling channel 11 in the side wall of cylinder body 1
