Description

Defroster

Technical field

The present invention 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 are relatively low.When winter overhauls to dedusting water pipe, water in dust removal Bursting by freezing phenomenon often occurs for pipe, and maintenance maintenance is all very troublesome, expends a large amount of manpower and materials, and cost is high.

The content of the invention

It is an object of the invention to provide a kind of defroster, prevents dedusting water pipe winter bursting by freezing, reduces entreprise cost.

Defroster of the present invention, including the Anti-freezing drain pipe located at dedusting water pipe bottom, Anti-freezing drain pipe bottom Provided with penstock, sealed plastic pipe is provided with Anti-freezing drain pipe, the sealing of sealed plastic pipe upper end, sealed plastic pipe lower end is sleeved on In connecting tube, connecting tube is set through Anti-freezing drain pipe, and connecting tube outer end is provided with air valve, and sealed plastic pipe upper end probes into dedusting In water pipe.

During winter, penstock is opened, by the water emptying in dedusting water pipe, then opens Non-return air valve door to sealed plastic pipe In be filled with gas, close penstock, be then shut off air valve.If the increasing of icing phenomenon volume occurs for remaining water in dedusting water pipe Big to produce expansive force, closed plastic pipe is flattened, has buffered expansive force, prevented expansive force from causing dedusting water pipe spalling by expansive force.

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

It is further preferred that the first waterproof cloth, sealed plastic pipe and dead ring are provided 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 invention are as follows：

The present invention first passes through penstock discharge by setting Anti-freezing drain pipe and sealed plastic pipe and air valve, during winter Water in dedusting water pipe, for remaining water, expansive force when can reduce water freezing by flattening closed plastic pipe, pass through two kinds Measure prevents dedusting water pipe from freezing crack；By setting Non-return air valve door, the air in plastic tube can be discharged, further reduces expansion Power, place dedusting water pipe from freezing crack.

Brief description of the drawings

Fig. 1 is the structural representation of one embodiment of the invention,

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

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

Embodiment

The present invention is described further with reference to embodiment：

As shown in Fig. 1~Fig. 2, defroster of the present invention, including the Anti-freezing drain pipe located at the bottom of dedusting water pipe 1 3, the bottom of Anti-freezing drain pipe 3 is provided with penstock 6, is provided with sealed plastic pipe 2 in Anti-freezing drain pipe 3, the upper end of sealed plastic pipe 2 is close Envelope, the lower end of sealed plastic pipe 2 are sleeved in connecting tube 4, and connecting tube 4 is set through Anti-freezing drain pipe 3, and the outer end of connecting tube 4 is provided with Air valve 5.Air valve 5 can be Non-return air valve door.The upper end of sealed plastic pipe 2 is probeed into dedusting water pipe 1.Connecting tube 4 connects close Envelope plastic tube 2 one end is provided with screw thread, and dead ring 7 is provided with matched internal thread, and connecting tube 4 is connected by dead ring 7 and sealed Plastic tube 2.The first waterproof cloth 9 is provided between connecting tube 4 and sealed plastic pipe 2, is provided between sealed plastic pipe 2 and dead ring 7 Second waterproof cloth 8.Dedusting water pipe 1 and Anti-freezing drain pipe 3 are by being welded to connect.Pass through weldering between connecting tube 4 and Anti-freezing drain pipe 3 Connect in succession.

During installation, the bottom of dedusting water pipe 1 is cut out into a circular port, Anti-freezing drain pipe 3 is welded on circular port；By One waterproof cloth 9 is around the end of thread of connecting tube 4, and by sealed plastic pipe, 2 sets are attached to the end of thread of connecting tube 4, then, by the second waterproof cloth Dead ring 7 around one end of the socket of sealed plastic pipe 2 connection 4, is tightened to the end of thread of connecting tube 4 by 8.After the completion of, in connecting tube 4 The other end installs air valve 5, opens air valve 5, is filled with proper amount of gas, and sealed plastic pipe 2 then is passed through into connecting tube 4 and antifreeze The connector of drainpipe 3 fills in Anti-freezing drain pipe 3, and then, connecting tube 4 is welded on Anti-freezing drain pipe 3.

The course of work or operation principle：

During winter, penstock 6 is opened, by the water emptying in dedusting water pipe 1, then opens Non-return air valve door to sealed plastic Gas is filled with pipe 2, penstock 6 is closed, is then shut off Non-return air valve door.If remaining water freezes in dedusting water pipe 1 The increase of phenomenon volume produces expansive force, and expansive force flattens closed plastic pipe 2, and gas can be by unidirectional in closed plastic pipe 2 Air valve is discharged, and has been buffered expansive force, has been prevented expansive force from causing the spalling of dedusting water pipe 1.

To the direction of structure and the description of relative position relation in the present invention, such as upper and lower description all around, not structure Into limitation of the present invention, only for convenience of description.
