Abstract
The utility model discloses a condensation water blowdown valve comprising a condensation water channel, wherein the condensation water channel comprises a front section and a rear section, a fall exists between the front section and the rear section, the front end of the front section is provided with a water inlet port connected with a condensation water draining pipeline, and the rear end of the rear section is provided with a water outlet port connected with the condensation water draining pipeline; the connection position of the front section and the rear section of the condensation water channel is connected with a blowdown pipe, and the tail end of the blowdown pipe is provided with a detachable blowdown cap in a covering way; and the difference of level between the front section and the rear section is 0.5-2 CM. The condensation water blowdown valve has low manufacturing cost, is simple and convenient for maintenance, and is smooth in water draining as the condensation water draining pipeline is difficultly plugged.
Description
Technical field
The utility model relates to a kind of blowoff valve, particularly a kind of condensed water blowoff valve.
Background technology
As shown in Figure 1, large-scale refrigeration plant is collected by open condensed water pallet 11 by the condensed water that fan coil produces such as central air-conditioning, flows into drain header 13 through branch drain 12 again, enters sewer at last again.Because air-conditioning service life, long (Air-conditioner design service life be 30-50) year in and year out, assembled full dust and various discarded object in the condensed water pallet 11.Branch drain 12 commonly used now and drain header 13 all can guarantee certain natural grade (the designing requirement gradient 〉=8 ‰, actual installation are difficult to reach) when mounted, discharge to make things convenient for condensed water.But when condensed water discharges in the air-conditioning system at present, do not do any processing and just directly be discharged into drainage pipeline, this wherein must contain a large amount of dusts and various discarded object, and consideration space requirement, the drainpipe diameter that adopts is all less, general a plurality of branch drain 12 shared drain headers 13 so just are easy to occur condensate draining pipe and stop up, and cause impeded drainage.
When occurring condensed water impeded drainage phenomenon at present, generally adopt air compressor machine to aspirate, but because condensate system is as shown in Figure 1 an open system,, and can not tackle the problem at its root so this mode can only to a certain degree be alleviated; Sometimes even run counter to desire, air compressor machine suction or the power of blowing cause drainpipe to stop up, and need again stringing or search stifled point, waste time and energy, and cause very large economy loss.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provide a kind of safeguard simple and convenient, cost is low, be not prone to drainpipe clogging and the condensed water blowoff valve one-body molded easily, that cost of manufacture is low.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of condensed water blowoff valve, comprise condensation water channel, this condensation water channel is made of leading portion and back segment, there is a drop between this leading portion and the back segment, and the leading portion front end is provided with the water inlet interface that is connected with the condensate draining pipe road, and the back segment rear end is provided with the water outlet interface that is connected with the condensate draining pipe road; The leading portion of this condensation water channel is connected with the back segment interface a blow-off pipe, and the end cap of this blow-off pipe is established dismountable blowdown cap.
Described drop is 0.5CM-2CM.
Form an angle between the back segment of described blow-off pipe and condensation water channel.
Described corner dimension is 30 degree-70 degree.
Described condensed water blowoff valve is made by PVC, PPR, ABS, PE or galvanized pipe.
Described water inlet interface, water outlet interface adopt screw thread mouth or straight-through interface.
Compared with prior art, the beneficial effect that the utility model had is: the utility model is by the blow-off pipe structure of simple passage and band blowdown cap, realized the contamination precipitation of condensed water, make condensate draining pipe road draining smoothness, be difficult for to stop up, also make the maintenance of condensate discharge system of large-scale refrigeration plant more simple and convenient simultaneously.The utility model is simple in structure, is fit to integrated die sinking production, and adopts drainage pipe commonly used, so low cost of manufacture, suitable user selects for use.

The specific embodiment
As shown in Figure 2, the utility model comprises condensation water channel 1, this condensation water channel 1 is made of leading portion 20 and back segment 21, drop H between leading portion 20 and the back segment 21 is 0.5CM-2CM, leading portion 20 front ends are provided with the water inlet interface 2 that is connected with the condensate draining pipe road, and back segment 21 rear ends are provided with the water outlet interface 3 that is connected with the condensate draining pipe road; And the leading portion 20 of this condensation water channel 1 is connected with back segment 21 interfaces a blow-off pipe 4, and the end cap of this blow-off pipe 4 is established dismountable blowdown cap 5.Form an angle a between the back segment 21 of this blow-off pipe 4 and condensation water channel 1, this angle a is generally 30 degree-70 degree.The utility model can adopt the material manufacturing with the identical material in condensate draining pipe road, as PVC, PPR, ABS, PE or galvanized pipe.This water inlet interface 2, water outlet interface 3 can adopt screw thread mouth (internal thread, movable nut), interface such as straight-through.
As shown in Figure 3, during the utility model 9 utilizations, it laterally is located at end-equipment condensed water discharge outlet, also can on branch drain 12 and drain header 13, installs.During the utility model installing, the interface 2 of will intaking connects condensate draining pipe road front end, and water outlet interface 3 connects rear end, condensate draining pipe road.When the condensation flow of band impurity during through the utility model, condensed water at first enters from water inlet interface 2, because the water yield of condensed water is very little, flow velocity is very low, therefore condensed water is introduced into blow-off pipe 4, after natural sedimentation, impurity accumulates to the lowest part of blow-off pipe 4, because the leading portion 20 of passage 1 and the drop that has 0.5CM-2CM between the back segment 21, the discrepancy in elevation that is to say the water inlet two ends of blow-off pipe 4 is 0.5CM-2CM, condensed water and impurity are fully admixed in gradient flow process, guarantee that impurity lighter than water, that be melted into water normally flows away.When the condensed water height in the blow-off pipe 4 surpasses the height of back segment 21 of condensation water channel 1, the condensed water of post precipitation will enter in the condensate draining pipe road through water outlet interface 3 again, that is to say that condensed water must pass through blow-off pipe 4, water outlet interface 3 enters in the drainage pipeline again under the unobstructed situation of draining.When air-conditioning to annual maintenance season, the surfaceman only need open blowdown cap 5, resets behind the cleaning impurity, just can guarantee that the condensate system draining is unobstructed.
If impurity is too much, excessive, or fails to clear up on time, when causing blow-off pipe 4 collection to expire foreign material, condensed water also can pass through condensation water channel 1 normal draining, impurity can precipitate by the next condensed water blowoff valve in the drainage pipeline, blowdown, can not cause drainage pipeline to stop up, and drainage takes place.
