Description
Technical field
This utility model belongs to rail traffic vehicles air conditioner technical field, is specifically related to a kind of high-speed train air-conditioning row
Water system suck-back device.
Background technology
Along with the fast development of science and technology, increasing bullet train travels on all over the motherland, fast to meet the people masses
The needs of speed trip.While train quantity and circuit increase, train runs into the time that two cars cross or travel in tunnel
Will be more and more longer.Train crosses at two cars or enters in tunnel running, and the air around train is compressible fluid, row
Car surface pressing is malleation and is increased dramatically, and now the outer undressed air stream of car carries condensation water by air conditioning unit row
Waterpipe enters railway car, makes pressure transient fluctuation in compartment very big, deteriorates the environment in car, and reduce in compartment is comfortable
Degree and the quality of air, make passenger seriously do not feel like oneself.
The drainage system designing a kind of suck-back device to be applied to high-speed train air-conditioning it is necessary for this.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of high-speed train air conditioner drainage system suck-back device, in draining
Being provided with anti-suck mechanism on pipe, the catch in anti-suck mechanism is pushed aside and is reached by the discharge pressure given by draining pump when draining
To draining purpose, when non-draining, then catch realizes anti-suck work in the effect lower limit of extension spring on the inner face installing pipe box
With.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of high-speed train air-conditioning draining system
System suck-back device, including be arranged on the drain pan of air conditioning chamber's intracavity bottom, the draining pump of water inlet communicated drainage dish and with row
The drain pipe that the outlet of water pump is connected, it is critical only that: be provided with anti-suck mechanism on drain pipe, in described anti-suck mechanism
Including the stepped installation pipe box in the cross section communicated with drain pipe, be set in parallel in installation pipe box in and be positioned at same vertical plane
In upper installation axle and lower jointed shaft, two the semicircle catch being hinged on lower jointed shaft and be separately positioned on two catch and
The extension spring of upper installation between centers.
Advantageous Effects of the present utility model is: 1, transported by the combination of draining pump with anti-suck mechanism and U-tube
With, it is ensured that when the situation that indoor chamber is negative pressure of air-conditioning does not occur suck-back phenomenon；2, the discharge pressure of draining pump controls anti-suck
The pushing aside of catch in mechanism, to discharge hydrops smoothly, when not draining, the catch in anti-suck mechanism is pressed under the effect of extension spring
Tightly play anti-suck effect at the inner face installing sleeve pipe；3, drain pan upper limb arranges switch, can automatically control draining pump
Operation or stopping, it is to avoid hydrops is too much.
Below in conjunction with the accompanying drawings this utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model high-speed train air conditioner drainage system suck-back device embodiment one；
Tu2Shi Tu1Zhong anti-suck mechanism is in structural representation during anti-suck state；
Tu3Shi Tu1Zhong anti-suck mechanism is in structural representation during hull-borne；
Fig. 4 is the structural representation of this utility model high-speed train air conditioner drainage system suck-back device embodiment two.
In the accompanying drawings: 1 is air conditioning chamber's inner chamber, and 2 is drain pan, and 3 is draining pump, and 4 is drain pipe, 5 is to install pipe box, and 6 are
Upper installation axle, 7 is lower jointed shaft, and 8 is catch, and 9 is extension spring, and 10 is switch, and 11 is U-tube, and 12 is vaporizer.
Detailed description of the invention
Embodiment one: see accompanying drawing 1-3, this utility model provides a kind of high-speed train air conditioner drainage system anti-suck dress
Put, including the drain pan 2 being arranged on bottom air conditioning chamber's inner chamber 1, the draining pump 3 of water inlet communicated drainage dish 2 and with draining pump 3
The drain pipe 4 that outlet is connected, it is critical only that: be provided with anti-suck mechanism on drain pipe 4, described anti-suck mechanism includes
The installation pipe box 5 stepped with the cross section that drain pipe 4 communicates, be set in parallel in installation pipe box 5 in and be positioned at same vertical plane
In upper installation axle 6 and lower jointed shaft 7, two the semicircle catch 8 being hinged on lower jointed shaft 7 and be separately positioned on two gears
Extension spring 9 between sheet 8 and upper installation axle 6.
The when of not draining, two catch 8 are pressed on the inner face installing pipe box 5 under the effect of extension spring 9, play anti-
The most extraneous water enters railway car through drain pipe 4, air conditioning chamber's inner chamber 1.
During draining, the pressure of draining pump 3 feedwater is relied on to overcome the pulling force of extension spring 9 to be pushed aside catch 8, so that drain pan
Water in 2 is discharged smoothly.
On drain pan 2, end face is provided with the switch 10 supporting with draining pump 3, and the liquid level on drain pan 2 realizes row
Automatically turning on of water pump 3.
Specific implementation process is as follows: air-conditioning device is when running refrigeration mode, and air is cooled when by vaporizer 12,
Saturated rear excessive moisture is condensed and is pooled in drain pan 2, and when condensed water reach a certain height, switch 10 closes,
Condensed water is expelled to outside air-conditioning device by drain pipe 4, anti-suck mechanism by draining pump 31.
When condensed water liquid level is less than draining pump 3 water sucking mouth, switch 10 disconnects, and draining pump 3 does not starts.Anti-suck machine
Structure plays sealing function and prevents the purpose of suck-back effect.
Embodiment two, see accompanying drawing 4, be provided with between the outlet and drain pipe 4 of draining pump 3 unlike embodiment one
U-tube 11.After the water in drain pan 3 is drained, in U-tube 11, still store a certain amount of water, there is gas in indoor chamber with the external world
During pressure reduction, in U-tube 11, the difference in height of water can equalize its pressure reduction, reaches sealing function and prevent suck-back together with anti-suck mechanism
The purpose of effect.
