Description
Technical field
The present invention relates to aerospace electric propulsion technologies, belong to vacuum tank technical field more particularly to a kind of solid-state work
Matter gasification flow automatic control device.
Background technology
Currently, in space electricity consumption propulsive working medium supply system, the gasification of solid-state working medium is coordinated by heater and throttle valve
Mode carries out：Directly solid-state working medium is heated by heater first, working medium is gasified in the case that heated by solid-state, then profit
The gas of generation is controlled with throttle valve, is supplied outward with flow as required.
The shortcoming of this supply system, which essentially consists in, is difficult to control solid-state working medium heating process.If heating time is not
Foot will cause the gas pressure inside container insufficient, cannot provide the flow of needs；If heating time is long, will cause to hold
Hypertonia inside device improves the requirement to container and throttle valve.It can be solved by addition active control system above-mentioned
Problem, but the complexity of system is increased simultaneously, the reliability of system is reduced, increases cost, and to the control of heater
It is formed with certain lag time, reduces the instantaneity of system.
Invention content
The present invention provides a kind of solid-state working medium gasification flow automatic control devices, can pass through simple mechanical control
System realizes that solid-state working medium gasification flow automatically controls, at low cost, instantaneity is strong.
To achieve the goals above, a kind of solid-state working medium of the invention gasification flow automatic control device includes constant pressure
Device, variable volume device, heater and gas circuit；
Variable volume device both ends seal, and solid-state working medium and heater, solid-state are fixed respectively on internal two opposing end surfaces
The outer surface at end where working medium and constant pressure device contacts；Constant pressure device is used to provide constant pressure for variable volume device
Power；Heater is used for heating and gasifying solid-state working medium；Gas circuit is connect by valve with bellows.
Wherein, the constant pressure device is constant force spring.
Wherein, the constant force spring with variable volume device is tangent contacts.
Wherein, the variable volume device is bellows.
Wherein, the supplement of solid-state working medium is realized by step-by-step movement supply mode.
Advantageous effect：
A kind of solid-state working medium gasification flow automatic control device of the present invention is of simple structure and low cost.The device can
Under preset parameter, the simple mechanical control system being made up of bellows and constant force spring realizes that reliability is high
Solid-state working medium gasification flow automatically controls.
Description of the drawings
Fig. 1 is a kind of solid-state working medium gasification flow automatic control device schematic diagram of the present invention.
Wherein：1- constant force springs, 2- bellowss, 3- heaters, 4- gas circuits, 5- holders.
Specific implementation mode
The present invention will now be described in detail with reference to the accompanying drawings and examples.
The flow automatic control device as shown in Figure 1, the solid-state working medium of the present embodiment gasifies, including constant force spring 1, bellows
2, heater 3, gas circuit 4 and holder 5,
2 both ends of bellows seal, and the confined space for providing a variable volume, one end is fixed on holder 5, heat
Device 3 is fixed on the inner surface held herein, and the other end and 1 outer of constant force spring are tangent, and solid-state working medium fixes the interior table in this end face
On face；Constant force spring 1 is used to provide constant pressure for bellows 2；Heater 3 is used for heating and gasifying solid-state working medium；Gas circuit 4 passes through
Valve is connect with bellows 2, and gaseous working medium is exported outward by gas circuit 4；Holder 5 is for constant force spring 1, bellows 2, heater
3 and the installation of gas circuit 4 fix.
Before the solid-state working medium gasification flow automatic control device operation of the present embodiment, bellows 2 is in compressive state, solid-state
Working medium is close to heater 3.After device is run, heater 3 begins to warm up solid-state working medium, and solid-state working medium is by thermal evaporation, generation work
Matter gas increases 2 internal pressure of bellows；When internal pressure is more than 1 pressure of constant force spring, constant force spring 1 is compressed, ripple
Pipe 2 starts to stretch, and reduces internal pressure to increase volume, and solid-state working medium is gradually detached with heater 3 in this process, until
The gasification of solid-state working medium stops.Working medium gas is conveyed outward by gas circuit 4, and internal pressure reduces, when pressure is pressed less than constant force spring 1
When power, 1 compress bellows 2 of constant force spring, 2 volume of bellows reduce, internal pressure increase, in this process solid-state working medium by
It is gradually close with heater 3, start until solid-state working medium gasifies, supplement internal gas again, generates Working medium gas and increase bellows 2
Internal pressure；When internal pressure is more than 1 pressure of constant force spring, constant force spring 1 is compressed again.Whole process repeats,
Until solid-state working medium is exhausted.
Constant force spring 1 can be substituted by other constant pressure devices that can provide；Bellows 2 can pass through other variable volume devices
Part substitutes.Solid-state working medium gasification rate is automatically adjusted as 2 volume of bellows changes.The supplement of solid-state working medium can pass through stepping
Formula supply mode is realized.
In conclusion the above is merely preferred embodiments of the present invention, being not intended to limit the scope of the present invention.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in the present invention's
Within protection domain.
