According to the device for draining the water from the vacuum environment to the normal pressure environment, the principle that water flows downwards is utilized, the fact that water in the vacuum environment is drained into the normal pressure environment is achieved, and the device for draining the water from the vacuum environment to the normal pressure environment has the advantages of being simple in structure, low in operation cost and capable of adapting work demands well.
Description
Technical field
The invention belongs to free jet ground simulation test technical field, be specifically related to a kind ofly can will enter the device under atmospheric pressure environments lower than the water under atmospheric pressure environments.
Background technology
Vacuum system is to supply with the system of test area injection exhaust and simulated altitude environment.Its pressure that first reduces vacuum reservoir by suction reaches the degree of vacuum of test demand, when test, open the conversion valve that is connected of vacuum reservoir and car test stand, first car test stand stratochamber pressure decreased is to certain pressure, after the work of car test stand main flow jet pipe, utilize the effect of receiving of vacuum reservoir, by the test air-flow of car test stand discharge and for the spraying cooling water of air-flow cooling use is incorporated into vacuum vessel, and in process of the test, remain in certain pressure and range of temperatures, to guarantee carrying out smoothly of test.
After end of test, in vacuum reservoir, be injected into a large amount of cooling waters.Though in tank, pressure rises to some extent after end of test, can not meet test demand, its pressure is still lower than bar pressure, in tank group system, there is the cooling water expansion tank spraying in a large number, if do not get rid of, the efficiency of the pressure that reduces vacuum reservoir is aspirated in impact again greatly, also reduces the life-span of aspirating pump group.
Therefore the device that needs a device liquid water retaining in vacuum reservoir can be got rid of in time, the running that this can be good for vacuum system, it is vital serving each free fluidized bed.
Summary of the invention
The object of the invention is: make up the deficiencies in the prior art, provide a kind of and water under vacuum environment can be entered to the device under atmospheric pressure environment.
Technical scheme of the present invention is: a kind of for vacuum environment the device to atmospheric pressure environment draining, it comprises: vacuum reservoir, upper drain hose, upper blowdown flange, liquid level switch, upper sluicing valve, displacement can, connection for bbreather pipe, down blow flange, lower drain hose and lower sluicing valve; Upper drain hose is triplate line, and its upper and lower two ports connect respectively bottom and the upper blowdown flange of vacuum reservoir, and the horizontal segment of upper drain hose is connected to displacement can by upper sluicing valve, is also provided with liquid level switch on the horizontal segment of upper drain hose;
Drain hose is triplate line, and its upper and lower two ports connect respectively bottom and the down blow flange of displacement can, and the horizontal segment of drain hose is provided with lower sluicing valve;
Displacement can is provided with connection for bbreather pipe;
The position of vacuum reservoir is higher than the position of displacement can.
The invention has the beneficial effects as follows: this device is to utilize the principle that The natural flow of water always proceeds from a higher level to a lower one, be communicated with respectively vacuum reservoir and atmosphere by displacement can, realize the water under vacuum environment is entered to atmospheric pressure environment, have simple in structure, operating cost is lower, can be good at adapting to work requirements.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, sluicing valve under drain hose, 10-under 1-vacuum reservoir, the upper drain hose of 2-, the upper blowdown flange of 3-, 4-liquid level switch, the upper sluicing valve of 5-, 6-displacement can, 7-connection for bbreather pipe, 8-down blow flange, 9-.
The specific embodiment
Referring to accompanying drawing 1, a device for from vacuum environment to atmospheric pressure environment draining, it comprises: vacuum reservoir 1, upper drain hose 2, upper blowdown flange 3, liquid level switch 4, upper sluicing valve 5, displacement can 6, connection for bbreather pipe 7, down blow flange 8, lower drain hose 9 and lower sluicing valve 10;
Displacement can 6 is provided with connection for bbreather pipe 7.
The position of vacuum reservoir 1 is higher than the position of displacement can 6, and upper drain hose 2 is connected to the water place of vacuum reservoir 1 lowest part, and passes into the upper end of displacement can 6; The lowest part of lower drain hose 9 in displacement can 6.
Concrete operation is when after end of test, as liquid level switch 4 shows while having ponding in upper drain hose 2, after under confirming, sluicing valve 10 and connection for bbreather pipe 7 are closed, sluicing valve 5 in unlatching, by upper drain hose 2, displacement can 6 will all be pressed with top vacuum reservoir 1, and ponding is introduced in the displacement can 6 of lower.After time delay certain hour (time is adjustable), first close and close sluicing valve 5, then open lower sluicing valve 10 and connection for bbreather pipe 7, displacement can 6 will all be pressed and tank internal water accumulation is discharged by the lower drain hose 9 of lower by connection for bbreather pipe 7 and atmosphere.After time delay certain hour (time is adjustable), close lower sluicing valve 10 and connection for bbreather pipe 7; When 4 demonstrations still have ponding as liquid level switch, can repeat above-mentioned steps, until ponding is drained.
Because this device is positioned at the lowest part of vacuum reservoir 1, in tank, have some dregs and get off along current, therefore on upper drain hose 2 and lower drain hose 9, be all provided with heavy dirty pipeline section, and blowdown flange 3 and down blow flange 8 are housed respectively.In the time that vacuum reservoir 1 recovers atmosphere pressure state, can open blowdown flange 3 and clear up dregs., can open down blow flange 8 and clear up dregs during in closed condition at upper sluicing valve 5.
