Description

Defroster

Technical field

This utility model relates to a kind of defroster, belongs to water pipe anti-freezing technical field.

Background technology

Winter temperature declines, and especially northern area, winter temperature is relatively low.When dedusting water pipe is overhauled by winter, water in dust removal Often there is bursting by freezing phenomenon in pipe, maintenance maintenance bothers the most very much, expends a large amount of manpower and materials, and cost is high.

Utility model content

The purpose of this utility model is to provide a kind of defroster, prevents dedusting water pipe bursting by freezing in winter, reduces entreprise cost.

Defroster described in the utility model, including being located at the Anti-freezing drain pipe of dedusting water pipe bottom, Anti-freezing drain pipe Bottom is provided with penstock, is provided with sealed plastic pipe in Anti-freezing drain pipe, and sealed plastic pipe upper end seals, and sealed plastic pipe lower end is overlapped Being contained in connecting tube, connecting tube runs through Anti-freezing drain pipe and arranges, and connecting tube outer end is provided with air valve.

During winter, open penstock, by the water emptying in dedusting water pipe, then open Non-return air valve door to sealed plastic pipe Middle insufflation gas, closes penstock, is then shut off air valve.If the water generation icing phenomenon volume of remaining increases in dedusting water pipe Producing greatly expansive force, sealed plastic pipe is flattened by expansive force, has buffered expansive force, has prevented expansive force from causing dedusting water pipe spalling.

It is further preferred that connecting tube connects sealed plastic pipe one end is provided with screw thread, dead ring is provided with matched interior Screw thread, connecting tube connects sealed plastic pipe by dead ring.It is completely embedded, prevents gas leakage.

It is further preferred that be provided with the first waterproof cloth, sealed plastic pipe and dead ring between connecting tube and sealed plastic pipe Between be provided with the second waterproof cloth.Prevent connecting tube and dead ring from damaging plastic tube.

It is further preferred that air valve is Non-return air valve door.

It is further preferred that dedusting water pipe and Anti-freezing drain pipe are by being welded to connect.

It is further preferred that by being welded to connect between connecting tube and Anti-freezing drain pipe.

Compared with prior art, the beneficial effects of the utility model are:

This utility model, by arranging Anti-freezing drain pipe and sealed plastic pipe and air valve, first passes through penstock during winter Discharge the water in dedusting water pipe, for remaining water, can pass through by flattening expansive force during sealed plastic pipe reduction water freezing Two kinds of measures prevent dedusting water pipe from freezing crack；By arranging Non-return air valve door, the air in plastic tube can be discharged, reduce swollen further Expansive force, places dedusting water pipe from freezing crack.

Accompanying drawing explanation

Fig. 1 is the structural representation of an embodiment of the present utility model,

Fig. 2 is connecting tube and sealed plastic pipe connection diagram.

In figure: 1, dedusting water pipe 2, sealed plastic pipe 3, Anti-freezing drain pipe 4, connecting tube 5, air valve 6, penstock 7, dead ring the 8, second waterproof cloth the 9, first waterproof cloth.

Detailed description of the invention

Below in conjunction with embodiment, this utility model is described further:

As shown in Fig. 1～Fig. 2, defroster described in the utility model, including the antifreeze row being located at dedusting water pipe 1 bottom Water pipe 3, is provided with penstock 6 bottom Anti-freezing drain pipe 3, be provided with sealed plastic pipe 2, sealed plastic pipe 2 upper end in Anti-freezing drain pipe 3 Sealing, sealed plastic pipe 2 lower end is sleeved in connecting tube 4, and connecting tube 4 runs through Anti-freezing drain pipe 3 and arranges, and connecting tube 4 outer end sets There is air valve 5.Air valve 5 can be Non-return air valve door.Connecting tube 4 connects sealed plastic pipe 2 one end and is provided with screw thread, dead ring 7 Being provided with matched female thread, connecting tube 4 connects sealed plastic pipe 2 by dead ring 7.Connecting tube 4 and sealed plastic pipe 2 it Between be provided with the first waterproof cloth 9, be provided with the second waterproof cloth 8 between sealed plastic pipe 2 and dead ring 7.Dedusting water pipe 1 and antifreeze draining Pipe 3 is by being welded to connect.By being welded to connect between connecting tube 4 and Anti-freezing drain pipe 3.

During installation, cut out a circular port by bottom dedusting water pipe 1, Anti-freezing drain pipe 3 is welded on circular port；By Sealed plastic pipe 2 set, around connecting tube 4 end of thread, is installed to connecting tube 4 end of thread, then, by the second waterproof cloth by one waterproof cloth 9 8 connect one end of 4 around sealed plastic pipe 2 socket, and dead ring 7 is tightened to connecting tube 4 end of thread.After completing, in connecting tube 4 The other end installs air valve 5, opens air valve 5, is filled with proper amount of gas, then by sealed plastic pipe 2 by connecting tube 4 and antifreeze Drain pipe 3 connector fills in Anti-freezing drain pipe 3, then, connecting tube 4 is welded on Anti-freezing drain pipe 3.

Work process or operation principle:

During winter, open penstock 6, by the water emptying in dedusting water pipe 1, then open Non-return air valve door to sealed plastic Insufflation gas in pipe 2, closes penstock 6, is then shut off Non-return air valve door.If the water of remaining freezes in dedusting water pipe 1 Phenomenon volume increases generation expansive force, and sealed plastic pipe 2 is flattened by expansive force, and in sealed plastic pipe 2, gas can be by unidirectional Air valve is discharged, and has buffered expansive force, has prevented expansive force from causing dedusting water pipe 1 spalling.

Direction and the description of relative position relation to structure in this utility model, such as the most upper and lower description, Do not constitute restriction of the present utility model, the most for convenience of description.
