Abstract
An antifreezing valve for a tap water pipe is characterized in that an antifreezing pipe is positioned in a tap water pipe, the upper end of the antifreezing pipe is fixed on a valve body (3) through a valve body (2), the valve body (3) is sleeved on the outer wall of the tap water pipe, a handle is arranged at the upper end of a piston pull rod, and a piston is sleeved at the lower end of the piston pull rod and is arranged in the antifreezing pipe. The contact part of the anti-freezing pipe and the valve body (2) is provided with a sealing ring. The anti-freezing pipe and the valve body (3) are communicated with the water outlet of the tap water pipe. The valve is simple in structure and convenient to use, and is an ideal anti-freezing device for outdoor use in winter of a water supply system.
Description
Technical field
The utility model relates to a kind of antifreezing valve body, particularly the tap-water pipe defrosting valve that winter, outdoor running water pipe used.
Background technique
Existing like product has following several types substantially: the one, and the automatic deflation type.It mainly is adapted to rural area non-tower water supply system, and when stopping to supply water, because of pipeline pressure reduces, ambient air enters pipeline by certain device, and water level is reduced to below the frozen soil layer, to reach antifreeze purpose.This series products often because of water droplet, water smoke in the means of deflation pipeline freeze lost efficacy; The 2nd, gas type.It is with power plant inflatable drainage in pipeline, and cost is often very high and use is inconvenient; The 3rd, dripping water type.Tap water flows with small flow, wastes self-evident; The 4th, prevent the bursting by freezing type.Make outdoor valve body with high strength or elastic material, volumetric expansion is broken when making it not freeze because of running water pipe.But this kind valve body can not solve pipeline and valve body because of freezing out of use problem.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of can solve effectively winter outdoor water supply pipe and valve body freeze can not water outlet even bursting by freezing problem, take straightforward procedure with the piston setting-out, as long as throttle down body, be pushed to the ponding in the vertical water supply pipe below the frozen soil layer downwards by piston, water supply pipe, valve body keep anhydrous state, to reach the tap-water pipe defrosting valve of antifreeze purpose.
The purpose of this utility model is achieved in that and comprises running water pipe, and its structure outline is: anti-frozen pipe is positioned at running water pipe, and its upper end is fixed on the valve body 3 by valve body 2, and valve body 3 is sleeved on the outer wall of running water pipe; The upper end of piston pulling rod is provided with handle, and the lower end is with piston, places in the anti-frozen pipe.
There is seal ring the contact position of described anti-frozen pipe and valve body 2.Described anti-frozen pipe is communicated with the water outlet of running water pipe with valve body 3.
Compared with prior art, the utility model is simple and practical, good freezing protection effect.Be applicable to not only regularly to feed water in the rural area and the outdoor straight pipeline of the 24 hours water supply systems in cities and towns antifreeze, also be applicable to the antifreeze of the outdoor fire hydrant of extremely frigid zones.
Description of drawings
Accompanying drawing is the utility model section of structure.
Embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
As accompanying drawing, the utility model is prevented compositions such as frozen pipe, piston and piston rod by running water pipe, valve body 2,3.Valve body 3 is used to connect water supply pipe and fixing anti-frozen pipe.Valve body 2 is used for anti-frozen pipe is fixed in valve body 3, and seals the water in the space between original inner-walls of duct and anti-frozen pipe 7 outer walls, and it can not be flowed out by the valve body body.As accompanying drawing, anti-frozen pipe 7 is positioned at running water pipe 5, and its upper end is fixed on the valve body 3 by valve body 2, and valve body 3 is sleeved on the outer wall of running water pipe 5.Anti-frozen pipe 7 has seal ring 4 with the contact position of valve body 2.Anti-frozen pipe 7 is communicated with the water outlet 9 of running water pipe 5 with valve body 3.
The upper end of piston rod 8 is provided with handle 1, and the lower end is with piston 6, places in the anti-frozen pipe 7.Piston 6, piston rod 8 are main movable parts, and upwards handle 1 can make water outwards flow out along anti-frozen pipe 7, valve body body 2.Promote downwards, then can with hydraulic pressure to frozen soil layer, reach antifreeze purpose.
During installation, anti-frozen pipe 7 is inserted into downwards below the frozen soil layer along original vertical water supply pipe 5, the same reliable connection with common valve gets final product.
If original pipeline is with new material manufacturings such as high strength plastics, aluminium-plastic composite pipes, inner wall smooth, desirable fire-fighting frozen pipe is directly installed on piston in original pipeline, promotes piston downwards and gets final product.
Claims (3)
1, a kind of tap-water pipe defrosting valve comprises running water pipe, it is characterized in that: anti-frozen pipe is positioned at running water pipe, and its upper end is fixed on the valve body (3) by valve body (2), and valve body (3) is sleeved on the outer wall of running water pipe; The upper end of piston pulling rod is provided with handle, and the lower end is with piston, places in the anti-frozen pipe.
2, tap-water pipe defrosting valve according to claim 1 is characterized in that: there is seal ring the contact position of anti-frozen pipe and valve body (2).
3, tap-water pipe defrosting valve according to claim 1 is characterized in that: anti-frozen pipe is communicated with the water outlet of running water pipe with valve body (3).
