Abstract

An anti-freezing unit for a tapping pipe mainly comprises a valve body 1, a through hole 2, a drain hole 3, a sealing ring 4, a column tube 5, a valve core 6, a through hole 7, a valve handle 8, a return hole 9, a connection rod 10, a protective tube 11, and a handle 12. The valve body is composed of the valve core disposed inside, the through hole positioned on a horizontal center line, the drain hole disposed at the center of one side of the through hole, and the sealing ring and the column pipe appended inside the drain hole. The valve core is composed of the through hole positioned on its horizontal center line, the valve handle disposed at the horizontal center, and the drain hole disposed at one side of the through hole. The drain hole locates at an opposite side to the return hole when the valve body and the two through holes on the valve body and the valve core form a straightforward state. The valve handle is in muff coupling with the connection rod with appropriate width and length under the protective tube. The handle is mounted on the upper end of the connection rod, or directly mounted on the valve handle. Upon shutdown of the anti-freezing unit under Open state of the tap, water inside a feeding standpipe naturally flows back and infiltrates downwards so that a cavity is formed inside the water pipe thus realizing freeze protection.

Description

The tap-water pipe defrosting device

One, technical field

The utility model tap water anti-freezing device belongs to the tap-water pipe defrosting technical field.

Two, background technology

Though existing tap-water pipe defrosting technology has make simple but use bothers, the complex structure and the cost that have are higher.

Three, summary of the invention

The objective of the invention is: a kind of tap-water pipe defrosting device is provided, solves outdoor tap water Guan Yi in winter that hundreds of millions of Chinese people expect for many years difficult problem that is frozen to ice.

The present invention is achieved in that mainly and is made up of parts such as valve body 1, through hole 2, spilled water hole 3, sealing ring 4, column jecket 5, spool 6, through hole 7, valve handle 8, backwater hole 9, connecting rod 10, pillar 11, handles 12.

Valve body: built-in spool, cross central line is established through hole, and spilled water hole is established at through hole one side center, adds sealing ring and column jecket in the spilled water hole.

Spool: cross central line is established through hole, and transverse center point is upwards established valve handle, and through hole one side is established backwater hole.

Spilled water hole: valve body and spool are combined as two through holes forward during state, and spilled water hole and backwater hole respectively occupy a side.

Valve handle: socket thickness, length are suitable and the connecting rod of pillar is arranged, and small end is installed handle, perhaps direct installation handle on valve handle.

The beneficial effect of the technology of the present invention is: simple in structure, to install easily, and running water pipe does not need defroster often to be left when antifreeze, and a switch water tap is to reduce the infiltration loss.

Four, description of drawings

1 valve body, 2 through holes, 3 spilled water holes, 4 sealing rings, 5 column jeckets, 6 spools, 7 through holes, 8 valve handles, 9 backwater holes, 10 connecting rods, 11 pillars, 12 handles.

Five, the specific embodiment

During installation, the tap-water pipe defrosting device placed close shape, as seen the backwater nose end is a water inlet end, it is flushed on the groundwater supply pipeline, with the other end is that the water side flushes in outlet pipe, connecting rod upwards with brick or stone build support, is filled and led up with soil after adding a cover Polypropylence Sheet above below defroster and around the column jecket.

When the running water pipe need are antifreeze, water tap is taken off or often places " driving valve discharges water " shape, turn 90 degree clockwise and close defroster, the interior water of standpipe this moment flows into through hole through backwater hole, flow out through spilled water hole, column jecket again and permeate the ground, make running water pipe form cavity, thereby realize the tap-water pipe defrosting purpose.

When tap water does not need defroster often to be placed " driving valve discharges water " shape when antifreeze, a switch water tap is to reduce the infiltration loss.

Claims

1, a kind of tap-water pipe defrosting device, it is characterized in that: valve body and spool respectively have a through hole, and the spilled water hole of two through holes valve body one side forward time the and the backwater hole of spool one side respectively occupy a side, connective pole or handle on the valve handle.

2, tap-water pipe defrosting device according to claim 1, the feature of its valve body is: built-in spool, cross central line is established through hole, and spilled water hole is established at through hole one side center, adds sealing ring and column jecket in the spilled water hole.

3, tap-water pipe defrosting device according to claim 1, the feature of its spool is: cross central line is established through hole, and transverse center point is upwards established valve handle, and through hole one side is established backwater hole.

4, tap-water pipe defrosting device according to claim 1, the feature of its spilled water hole is: valve body and spool are combined as two through holes forward during state, and spilled water hole and backwater hole respectively occupy a side.

5, tap-water pipe defrosting device according to claim 1, the feature of its valve handle is: the connecting rod of the suitable and overcoat pillar of valve handle socket thickness, length, small end is installed handle, or on valve handle direct installation handle.
