The booster 1 and the booster control valve 2 are used to control the boosting of a first tank 3, a second tank 4, and a third tank 5, the first tank 3 stores a working medium, the second tank 4 stores fuel a, and the third tank 5 stores fuel B.
Through the structure, the gas injection expansion actuating system with simple structure, convenient control, safety, reliability and strong practicability is formed. During operation, the supercharger 1 is started, the supercharging control valve 2 is opened, and the first storage tank 3, the second storage tank 4 and the third storage tank 5 are supercharged through the corresponding pipelines respectively. When the pressure in the first reservoir 3 rises to the corresponding set value, the first pressure valve 31 is opened and the working medium enters the reactor 6 through the first pressure valve 31. When the pressures of the second and third tanks 4 and 5 rise to the corresponding set values, the second and third pressure valves 41 and 51 are opened, and the fuel a will enter the reactor 6 through the second pressure valve 41 and the fuel B will enter the reactor 6 through the third pressure valve 51. The fuel A and the fuel B are subjected to combustion reaction in the reactor 6 and release heat, and the actuating medium in the reactor 6 absorbs the heat and then undergoes phase change to generate high-pressure gas. When the pressure of the reactor 6 rises to the corresponding set value, the actuating pressure valve 71 is opened, and the high-pressure gas enters the actuating pressure chamber 72 through the actuating pressure valve 71 and pushes the counterweight 8 to move, thereby achieving the technical purpose of actuation. According to the invention, the first storage tank 3, the second storage tank 4, the third storage tank 5, the reactor 6 and the guide cylinder 7 are arranged, so that the physical separation of the energy storage function and the heat absorption work function is realized, and compared with the existing gas injection actuating device, the gas injection actuating device effectively reduces the design difficulty and high-pressure risk and improves the safety.

Preferably, the present embodiment is provided with the first pressure reducing valve 42 in a pipe between the second tank 4 and the pressure increasing control valve 2, and the second pressure reducing valve 52 in a pipe between the third tank 5 and the pressure increasing control valve 2. The pressure of the pressure booster 1 can be reduced to an appropriate value by the first pressure reducing valve 42 and the second pressure reducing valve 52 so as to reasonably pressurize the second storage tank 4 and the third storage tank 5, on one hand, the control convenience is improved by separating the pressurization of the second storage tank 4 and the third storage tank 5 from the pressurization of the first storage tank 3, on the other hand, the pressure resistance requirement on the second storage tank 4 and the third storage tank 5 is reduced, and the safety is improved.

The pressurizing medium can be compressed air, compressed nitrogen or compressed helium, etc. However, the supercharger 1 is not limited to the use of a gas supercharger, and other types of supercharging devices may be used as long as the first reservoir 3, the second reservoir 4, and the third reservoir 5 can be supercharged. In practical application, carbon dioxide or nitrogen and the like can be used as an actuating medium for performing jet expansion work so as to realize liquefaction in the filling process and store the liquefied carbon dioxide or nitrogen in a gas-liquid saturated state, thereby reducing the storage volume. As the fuel for the combustion reaction, sodium nitrite can be used for fuel a, and ammonium chloride can be used for fuel B, but fuel a and fuel B are not limited to the combination of these two substances, and other combinations of substances may be used as long as the combustion reaction and heat release can be achieved. The first pressure valve 31, the second pressure valve 41, the third pressure valve 51 and the actuation pressure valve 71 can be various types such as a regulating valve, a reducing valve or a pressure maintaining valve; the first pressure reducing valve 42 and the second pressure reducing valve 52 may be piston type pressure reducing valves or pilot type pressure reducing valves. In addition, in order to facilitate the detection of parameters such as pressure, flow rate, temperature and the like, corresponding detection elements can be arranged at required positions so as to improve the control accuracy.
Based on the same conception, the invention also provides a control method of the gas injection expansion actuating system, which comprises the following steps:
firstly, starting the booster 1, opening the booster control valve 2, and respectively introducing a boosting medium into a first storage tank 3, a second storage tank 4 and a third storage tank 5 through respective corresponding pipelines.
When the pressure in the first storage tank 3 rises to P1, the first pressure valve 31 is opened, and the working medium enters the reactor 6 through the first pressure valve 31.
And thirdly, when the pressure of the second storage tank 4 and the third storage tank 5 rises to P2, the second pressure valve 41 and the third pressure valve 51 are opened, the fuel a enters the reactor 6 through the second pressure valve 41, and the fuel B enters the reactor 6 through the third pressure valve 51.
Fourthly, the fuel A and the fuel B are subjected to combustion reaction in the reactor 6 and release heat, and the actuating medium in the reactor 6 absorbs the heat and then undergoes phase change to generate high-pressure gas.
And fifthly, when the pressure of the reactor 6 is increased to P3, the actuating pressure valve 71 is opened, and high-pressure gas enters the actuating pressure cavity 72 through the actuating pressure valve 71 and pushes the counterweight 8 to move.
The above-mentioned P1 is the cracking pressure set value of the first pressure valve 31, P2 is the cracking pressure set value of the second pressure valve 41 and the third pressure valve 51, and P3 is the cracking pressure set value of the operating pressure valve 71.
