Description
Technical field
The utility model belongs to the air conditioner apparatus field, particularly relates to a kind of air-conditioning unit negative pressure condense water disk pulse water trap.
Background technology
Air-treatment unit (also claiming the air-conditioning unit) is installed the surface-cooler (abbreviation surface cooler) that is used to cool off air usually, its bottom has one to coagulate water pond, be used to get rid of the cooling condensed water that air produced, during the Air-conditioning Engineering construction, to take over the water seal arrangement of installation qualification for the condense water disk draining, water seal is installed needs certain spatial altitude, at first to there be the air-conditioning unit of enough height that the basis is installed, Fig. 2 and Fig. 3 are seen in the water seal height specific requirement, wherein, h is equivalent to the height of pitot-static pressure part, and H deducts height of foundation must add operating space (about 50mm) more than or equal to 2 times of pitot-static pressure height.Blower fan pitot-static pressure in the air-conditioning unit can be looked into the sample performance curve, or the total head value (Pa) on the blower fan nameplate is deducted unit outlet dynamic pressure value (Pa) can obtain the inboard maximum pitot-static pressure value of water section with fixed attention, its value is equivalent to the water-column (mm) of pitot-static pressure divided by 10 numerical value that obtain, and the water seal total height will have two times of static pressure water-columns could safety to discharge to coagulate water.If the ventilation blower of air-conditioning unit is at the downstream part of surface cooler, then coagulate water pond and be in negative pressure state, if water seal height is lower than requirement, unit is normal after wet cooling condition operation a period of time in summer, and that water takes place to coagulate is excessive in coil, in unit, flow out outside the unit again, make machine room ponding, this situation should be avoided.If the ventilation blower of air-conditioning unit, then coagulates water pond at the upstream end of surface cooler and is in barotropic state, if water seal height is lower than requirement, unit can make the trap lack of water after wet cooling condition operation in summer, lose the water seal effect.
In China's various places engineering practice, air-conditioning unit negative pressure is coagulated water pond adapter water seal height deficiency and is caused that unit spilling water phenomenon is easier to produce, main cause is when the lower Air Conditioning Facilities of head room are constructed, it is bigger to run into unit volume, highly higher, and above the unit larger-size ajutage is arranged, and will cause height of foundation not meet the demands, the water seal height that coagulates water swivel can't be up to standard.Also have indivedual workmens to lack experience, Equipment Foundations and water seal height are chosen highly wrong, have influenced the air-conditioning unit and have normally moved.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of air-conditioning unit negative pressure condense water disk pulse water trap, can't reach the difficult problem that requirement is caused with on the low side the construction with the curved water seal height of double-H groove weld word in the unit basis that solves existing Air Conditioning Facilities.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of air-conditioning unit negative pressure condense water disk pulse water trap is provided.The shell, U word bend pipe, ball float I, reducing coupling, ball float II, inner connecting tube I, inner connecting tube II, T shape pipe and the protection network that comprise water trap.
Its principle is, when the pulse water trap is used, the air-conditioning unit begins to cool down air and produce to coagulate water and can drop on fixed attention and take in the U word bend pipe that slowly flows in the pulse water trap by coagulating water in the water pond again, when ponding height during greater than ball float I, after the ball float I of little quality floats, water will flow out from spillway hole, ponding can slowly raise in the water trap, and when ponding was higher than in the pulse water trap ball float II in the T shape pipe (special-shaped t-bend pipe), ball float II floated, water is discharged in the pipeline, finishes drainage procedure.When the air-conditioning unit coagulates negative pressure in the water pond when higher, behind the unit operation, can seal by the ball float I of suction function U word bend pipe, the ball float II of T shape pipe (special-shaped t-bend pipe) also will seal, and prevent that air from entering in the water trap.
Its structure is, U word bend pipe is positioned at shell, one is fixed on the shell wall by interior outer nut I, and can be connected with the water pipe that coagulates that coagulates water pond, the other end is connected with the reducing coupling by inner connecting tube I, ball float I is stuck on the inner connecting tube I can be airtight or float, the reducing coupling of ball float I top has spillway hole, the condensed water of air-conditioning unit can flow in the container by spillway hole after ball float floats, T shape pipe is fixed on the shell wall by interior outer nut II, built-in inner connecting tube II, the bottom is communicated with the water trap inner space, ball float II is stuck on the inner connecting tube II can be airtight or float, and protection network is positioned at T shape inside pipe wall can prevent that ball float drifts out outside the pipe, but the ponding in the container holds up behind the ball float II outside the discharge pipe.
Described T shape pipe (special-shaped t-bend pipe) and U word bend pipe and shell junction are fixed by sealing ring and interior outer nut.
Described inner connecting tube I and inner connecting tube II are hollow cylindrical structure.
Described ball float I and ball float II are hollow ball.
Behind the air-conditioning unit summer operation, coagulate water pond ponding and enter the pulse water trap, under certain ponding pressure, the ball float I of U word bend pipe can float, coagulating water flows out from spillway hole, ponding slowly raises in the water trap, after the water pond water level is reduced to a certain degree with fixed attention in the air-conditioning unit, to impel negative pressure to work again, ball float I falls sealing U word bend pipe, coagulate water and flow out from U word bend pipe spillway hole and periodically and not necessarily recur, when the ponding in the water trap is higher than in the pulse water trap ball float II in the T shape pipe (special-shaped t-bend pipe), after ball float II floats, water can be discharged in the pipeline, in case water level reduces in the water trap, ball float II will seal again in the T shape pipe (special-shaped t-bend pipe), and drainage procedure will stop.
The utility model can not satisfy the occasion use of water seal height at air-conditioning unit height of foundation.Be not less than in the Air Conditioning Facilities of 150mm and use coagulating water swivel center absolute altitude.The utility model should not be in using in the water swivel with fixed attention of barotropic state.Beneficial effect
The utility model coagulates the higher machine room of water pond negative pressure at the air-conditioning unit to be used, and key dimension is reduced, and helps the header pipe and installs, and reduces the constructional difficulties that causes because of setting height(from bottom) and the restriction of workmen's experience.
