Specific embodiment
In order to be easy to understand to technical means, creative features, achievable purpose and effectiveness of the invention, below with reference to tool
Body diagram, the present invention is further explained.
As shown in figs. 2-9, a kind of positive/negative-pressure condensate drain, including tank body 1, the side wall of tank body 1 are offered into water
Mouthful and water outlet, the height of water inlet be greater than the height of water outlet, the inner wall of inlet and outlet be respectively fixedly connected with into
Water pipe 5 and outlet pipe 2, water inlet pipe 5 are located at the fixation of the side in tank body 1 and are communicated with union elbow 11, one end of union elbow 11
Fixed to be communicated with liquid sealing pipe 12, the lower surface height of liquid sealing pipe 12 is lower than the height of water outlet, the top side detachable connection of tank body 1
There is capping 3.
Using the above scheme, the device is integrated by complicated flowing line, compact-sized, easy for installation, and positive pressure,
Negative pressure air-conditioner set condensed water elimination is applicable, avoids conventional discharge pipeline and is wanted by installation dimension requirement and positive/negative-pressure
Ask etc. the influence of limitation.
The center of capping 3 is equipped with transparent windows 4, can be with the drainage condition of condensed water in macroscopic examination tank body 1.
Union elbow 11 is 90 degree of elbows, and the height in the bottom of liquid sealing pipe 12 and tank body 1 between bottom is 25mm.
Using the above scheme, 90 degree of union elbow 11 makes liquid sealing pipe 12 in a vertical state, at the same liquid sealing pipe 12 with
Low tone in tank body 1 between bottom prevents negative inspiratory pressure away from the fluid-tight effect that ensure that the device.
The junction of water inlet pipe 5 and outlet pipe 2 is provided with pipe screw thread, convenient for being connected to water-collecting tray 9 and external pipeline.
The lateral wall bottom end of tank body 1 is fixedly connected with the equally distributed mounting plate 6 of multiple annulars, on multiple mounting plates 6
It is provided with screw bolt and nut, which is fixed on house furred ceiling by mounting plate 6 and bolt, or on computer room ground
On be fixed.
The insulating layer of 25mm thickness is additionally provided on tank body 1.
Using the above scheme, tank body 1 and insulating layer are made of sandwich-type, i.e., 1 side wall of tank body is set as hollow thin
Wall construction, insulating layer are filled in the hollow part in tank body 1, can effectively prevent 1 surface sweating of tank body.
Tapping equipment is generally stainless steel welded to be formed, and production is simple, and weatherability is strong, long service life.
As shown in fig. 7, the blower in air-conditioner set will form negative pressure when starting, the negative pressure in unit can be drawn in tank body 1
Condensed water, will form liquid level h identical with negative pressure value in unit, therefore the Design of length of liquid sealing pipe 12 in liquid sealing pipe 12
It needs to be greater than liquid level h, the condensate drain of different pressures value can also be made according to customer requirement.
Working principle: applying in negative pressure condensed water elimination, and as shown in Figure 7 and Figure 8, water inlet pipe 5 connects water-collecting tray 9, by
In condensed water water inlet pipe 5 on top, under the action of unit negative pressure, the liquid level inside tank body 1 plays the role of sealing, prevent
Only air suck-back, and when the condensed water liquid level in unit in water-collecting tray 9 accumulates to the water surface higher than outlet pipe 2, condensed water
Hydraulic pressure be greater than negative pressure value in unit, condensed water can continuously flow into tank body 1, and the liquid level in tank body 1 is increased to
At outlet pipe 2, and overflowed by outlet pipe 2.
It applies in positive pressure condensed water elimination, the link position of water inlet pipe 5 and outlet pipe 2 is exchanged, such as Fig. 9 institute
Show, at this time since outlet pipe 2 is in 1 lower part of tank body, and is connect with the drainpipe of the positive pressure section water-collecting tray 9 in unit, in unit
Under the action of positive pressure, liquid level inside liquid sealing pipe 12 due to unit positive pressure effect and be constantly raised, liquid level plays
The effect of sealing, prevents air to be discharged, and when the condensed water liquid level in unit in water-collecting tray 9 accumulates to certain altitude, it condenses
The hydraulic pressure of water adds the effect of positive pressure in unit, so that the liquid level in liquid sealing pipe 12 is increased at water inlet pipe 5, condensed water
It is overflowed by water inlet pipe.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, without departing from the spirit and scope of the present invention, this hair
Bright to will also have various changes and improvements, these changes and improvements all fall within the protetion scope of the claimed invention.The present invention claims
Protection scope is defined by the appending claims and its equivalent thereof.
