Abstract
A liquid rocket low temperature storage tank insurance system comprises a safety valve, a connecting hand valve, a test hand valve, inflation and deflation equipment, a test conduit and a connection conduit. When the system carries out a test, the connecting hand valve is closed and the test hand valve is opened and is connected with the ground inflation and deflation equipment. The safety valve receives pressure of the inflation and deflation equipment. When the pressure of the inflation and deflation equipment reaches valve opening pressure, the safety valve is opened. When the pressure of the inflation and deflation equipment is lower than safety valve closing pressure, the safety valve is closed. When the safety valve works, the test hand valve is closed so that the safety valve is connected with a tank body through the conduit and receives tank pressure. The system has the advantage that the test to the safety valve is realized under the condition that pressurization is not performed on the storage tank.
Description
Technical field
The utility model relates to the utility model and relates to a kind of liquid rocket Cryogenic tank insurance system, is applicable to the Cryogenic tank of large-scale liquid rocket.
Background technology
Liquids in general Rocket tank is all designed with easing valve, and in the time occurring that fortuitous event causes tank internal pressure extremely to raise, easing valve is opened, and unnecessary gas is discharged to tank.
At present, the safety valve test on tank is all passed through tank inflation, and the opening pressure that makes case pressure reach insurance valve is opened safety valve.But for the Cryogenic tank of large volume, conventionally utilize the intensity of cryogenic conditions lower box material to improve, alleviate the wall thickness of casing, reach the effect of loss of weight, therefore can not be inflated to tank at normal temperatures the opening pressure of easing valve, the performance that can not test safety valve when rocket is tested; In addition the tank volume of large-scale liquid rocket reaches hundreds of cubic meters, and using true tank test need to consume a large amount of gas mediums has increased the cost of test.
Utility model content
Technology of the present utility model is dealt with problems and is: the insurance system of realization to Cryogenic tank easing valve under a kind of normal temperature condition is provided.
Technical solution of the present utility model is:
A kind of liquid rocket Cryogenic tank insurance system, comprising: easing valve, connection hand valve, test hand valve, inflation/deflation equipment, test conduit and connecting tube;
Easing valve is installed on the top of described liquid rocket Cryogenic tank, and one end of connecting tube connects easing valve, and the other end is three-port structure, and connecting tube connects hand valve by this three-port structure, is communicated with hand valve and is connected to described liquid rocket Cryogenic tank; Inflation/deflation equipment is connected to test hand valve by test conduit, and test hand valve is communicated with the three-port structure of connecting tube again.
Described liquid rocket Cryogenic tank, easing valve, connecting tube and connection hand valve form loop.
The utility model beneficial effect is compared with prior art:
(1) the utility model can be realized and tank not carried out under the condition of pressurising, realizes the test to safety valve.
(2) the utility model, by can ground inflation/deflation equipment, only consumes a small amount of test gas medium in the test process of safety valve.
Accompanying drawing explanation
Fig. 1 is the utility model system architecture schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described in detail.
As shown in Figure 1, the utility model provides a kind of liquid rocket Cryogenic tank insurance system, comprising: easing valve 3, connection hand valve 1, test hand valve 2, inflation/deflation equipment 5, test conduit 6 and connecting tube 7;
In the time carrying out the test of the utility model insurance system, first close and be communicated with hand valve 1, open test hand valve 2, inflation/deflation equipment is first inflated easing valve 3 by test conduit 6, make easing valve 3 experience the true pressure in the Cryogenic tank that inflation/deflation equipment simulating goes out, in the time reaching the opening pressure of easing valve 3, easing valve 3 is discharged the gas in described Cryogenic tank.Afterwards, inflation/deflation equipment is discharged the gas in test conduit, test hand valve and connecting tube, and in the time that the pressure in inflation/deflation equipment reaches easing valve 3 closing presure, easing valve 3 cuts out, thereby realizes the test function to easing valve 3, in this process, without Cryogenic tank is inflated.
Complete after test, will test conduit and disconnect with test hand valve 2, and close test hand valve 2, open and be communicated with hand valve 1, realize the normal insurance function of easing valve.
Claims (2)
1. a liquid rocket Cryogenic tank insurance system, is characterized in that comprising: easing valve (3), connection hand valve (1), test hand valve (2), inflation/deflation equipment (5), test conduit (6) and connecting tube (7);
Easing valve (3) is installed on the top of described liquid rocket Cryogenic tank, one end of connecting tube (7) connects easing valve (3), the other end is three-port structure, connecting tube (7) connects hand valve (1) by this three-port structure, is communicated with hand valve (1) and is connected to described liquid rocket Cryogenic tank; Inflation/deflation equipment (5) is connected to test hand valve (2) by test conduit (6), and test hand valve (2) is communicated with the three-port structure of connecting tube (7) again.
2. a kind of liquid rocket Cryogenic tank insurance system according to claim 1, is characterized in that: described liquid rocket Cryogenic tank, easing valve (3), connecting tube (7) and connection hand valve (1) form loop.
