Abstract
The utility model provides a water drainage coiled pipe. The utility model has the technical proposal that elbows, copper pipes, vertical water inlet pipes and vertical water outlet pipes form a plurality of sets of loops, and the copper pipes in the loops are connected by the elbows. The utility model is characterized in that each set of loops is positioned in the same inclined surface. Water inlets are arranged on the upper side, and water outlets are arranged on the lower side. Besides, the inclined surfaces which the loops positioned in are mutually parallel. Under the precondition of unchanged pipe pass, the utility model can drain the water in the pipes completely and prevent the copper pipes from cracking caused by freezing. The utility model is suitable for being used in heat exchangers using the air and the water (or the steam) as the medium, especially in central air-conditioners.
Description
The utility model relates to and is used for sky G﹠W (or steam) and is heat exchanger one coil pipe of medium, particularly air conditioning coil pipe.
Present air conditioning coil pipe, form by some groups of loops, connect with elbow between the copper pipe in every group of loop, elbow is fixed on the pipe breast board, the shape that elbow is arranged is, from the direction of elbow, these elbows are arranged by zigzag, two-layer pipe will occur like this: low level pipe and high-order pipe.The problem of this arrangement mode is: in the time of in working order, the water in the low level pipe can't be discharged, and causes when the subzero operating mode the copper pipe bursting by freezing.
But the purpose of this utility model is to provide a kind of draining coil pipe of avoiding above-mentioned deficiency.
The purpose of this utility model is achieved in that it is by elbow, copper pipe, water inlet standpipe and water outlet standpipe are formed some groups of loops, connect with elbow between the copper pipe in the loop, elbow is fixed on the pipe breast board, and it is characterized in that: every group of loop is in the same inclined-plane, and the water inlet is last, delivery port is in down, and residing inclined-plane, every group of loop is parallel to each other.Because every group of loop is obliquely installed, so after drain valve was opened, the water in the coil pipe can be drained fully, reaches antifreeze purpose.
The utility model compared with prior art under the constant prerequisite of tube side, can be avoided the copper pipe bursting by freezing with the water emptying in the pipe.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
It is by elbow 2, copper pipe 5, water inlet standpipe 1 and water outlet standpipe 4 are formed seven groups of loops, connect with elbow between the copper pipe in the loop, elbow is fixed on the pipe breast board 3, and wherein Zhong Jian five groups of loops are: every group of loop is in the same inclined-plane, and the water inlet is last, delivery port is in down, and the inclined-plane in every group of loop is parallel to each other.The remaining connected mode that is in two loops at two diagonal angles is: from the direction of elbow, these elbows are by level and oblique alternately arrangement, because every group of loop tilts to place, so after drain valve is opened, water in the coil pipe can be drained fully, reaches antifreeze purpose
Claims (2)
1, but a kind of draining coil pipe, it is by elbow, copper pipe, and water inlet standpipe and water outlet standpipe are formed some groups of loops, connect with elbow between the copper pipe in the loop, elbow is fixed on the pipe breast board, and it is characterized in that: every group of loop is in the same inclined-plane, and the water inlet is last, delivery port is in down, and residing inclined-plane, every group of loop is parallel to each other.
2, but according to the described draining coil pipe of claim 1, it is characterized in that: it is made up of seven groups of loops, wherein Zhong Jian five groups of loops are: every group of loop is in the same inclined-plane, the water inlet is last, and delivery port is in down, and the inclined-plane in every group of loop is parallel to each other, the remaining connected mode that is in two loops at two diagonal angles is: from the direction of elbow, these elbows are by level and oblique alternately arrangement.
