Description
Technical field
The utility model relates to the humidification system of a kind of high low temperature alternating damp heat atmosphere chamber, relates in particular to a kind of automatic water supply device of high low temperature alternating damp heat atmosphere chamber humidification system.
Background technology
Existing high low temperature alternating damp heat atmosphere chamber humidification system generally comprises the steam supply case, water tank and water pump, water in the water tank is sent in the steam supply case by water pump, the steam supply case has heating function, can become steam to water, the effect of liquid water process steam supply case becomes steam and enters in the chamber, thereby build damp and hot environment for chamber and carry out every damp heat test, storage tank generally all is arranged on the chamber bottom, in the process of the test, water in the storage tank constantly reduces, need to add water for storage tank manually, very inconvenient by manually adding water, and in order to guarantee enough water is arranged in the storage tank when doing long-time damp heat test, need to often note the water level of water tank the inside, if fruit forgets that adding water can have a strong impact on test effect, even can damage the steam supply case.
Chinese patent Granted publication number: CN2743430Y, November 30 2005 Granted publication day, a kind of automatic water supply device is disclosed, comprise water pump, water storage pressure vessel, pump outlet connects the water storage pressure vessel, is provided with a check valve before pump intake, and pump working is controlled by pressure control switch, pressure control switch connects the pneumatic tube of water storage pressure vessel, and the pressure control switch break-make is controlled by the air pressure of water storage pressure vessel.Owing to be provided with a check valve before pump intake, the water of water storage pressure vessel can not reflux out, can keep container inner pressure, pump working is controlled by pressure control switch, and when the water of water storage pressure vessel is used to a certain degree, container inner pressure reduces, pressure control switch is connected, water pump energising work, toward the interior water storage of pressure vessel, water storage is arrived to a certain degree, container inner pressure increases, pressure control switch disconnects, and water pump quits work, thereby realizes the automatic water-supply function.This automatic water supply device, complicated integral structure inconvenient operation, whole system need larger air pressure just can keep the automatic water-supply function, just can't automatic water-supply in case air pressure is less than normal, so poor stability.
The utility model content
The utility model is in order to overcome automatic water supply device complex structure, inconvenient operation in the prior art, the deficiency that Simultaneous Stabilization is relatively poor, provide a kind of simple in structure, easy to operate, stability is good, thus the automatic water supply device of the normal steady operation of energy effective guarantee high low temperature alternating damp heat atmosphere chamber.
To achieve these goals, the utility model adopts following technical scheme:
A kind of automatic water supply device comprises storage tank and steam supply case, and described storage tank is connected with the steam supply case by water pump, is provided with water inlet pipe in the described storage tank, and the end of described water inlet pipe is provided with automatic feeding water mechanism.During high low temperature alternating damp heat atmosphere chamber work, water inlet pipe is connected with running water pipe, constantly supply water for storage tank, water in the storage tank is drawn in the steam supply case by water pump and heats, the demand of water is regulated by the equipment automatically controlled water pump in the steam supply case, after the liquid level in the storage tank reaches the height of standard, this moment water inlet pipe mouth automatic feeding water mechanism can autoshutdown water inlet, extraction along with water pump, liquid level in the storage tank can constantly descend, when liquid level dropped to certain height, automatic feeding water mechanism can open the water inlet moisturizing again automatically, and therefore whole apparatus structure is simple, very easy to use, need not the professional and keep an eye on, just can realize stable to high low temperature alternating damp heat atmosphere chamber humidification system automatic water-supply, thereby support equipment works.
As preferably, that described automatic feeding water mechanism comprises is cursory, connecting rod and be arranged on the ball-cock assembly of water inlet pipe water inlet, described cursoryly be connected with described ball-cock assembly by connecting rod, the middle part of described connecting rod is hinged with support bar, and the other end of described support bar and the bottom of storage tank are fixed.When not having water in the storage tank, ball-cock assembly is opened in cursory sinking, and the water inlet of water inlet pipe is opened water supply; Rising along with the water surface, cursory also constantly rising, when liquid level reached certain height, ball-cock assembly was closed the water inlet of water inlet pipe fully, so just stopped to supply water, can automatically open again ball-cock assembly when liquid level descends supplies water, iterative cycles keeps moisture storage capacity suitable in the storage tank, and whole apparatus structure is simple, and volume is little simultaneously, only be installed on the water inlet of storage tank inside, install very convenient.
As preferably, the bottom of described storage tank also is provided with outlet pipe, and the outflow end of described outlet pipe is provided with draining valve.After finishing experiment, remaining water can be discharged outside the storage tank by drainpipe in the storage tank, cleans simultaneously storage tank inside, and sewage also can be discharged by drainpipe, closes draining valve when equipment uses.
As preferably, the side of described storage tank is provided with overflow pipe, and the outer end of described overflow pipe is communicated with the draining valve outer end of described outlet pipe.Overflow pipe is in process of the test, when causing water inlet pipe to supply water if automatic feeding water mechanism is out of order always, this moment, unnecessary water can flow to device external by overflow pipe, can effectively place water in the storage tank and overflow storage tank and flow to experimental facilities inside outward testing equipment is caused damage.
Therefore, the utlity model has simple in structurely, easy to operate, stability is good, can the normal steady operation beneficial effect of effective guarantee high low temperature alternating damp heat atmosphere chamber.
