Description

Antifreeze water pipe

Technical field

The utility model relates to a kind of antifreeze water pipe.

Background technology

In northern arctic weather, temperature generally all reaches subzero tens degree, and this moment, exposed water pipe on the ground will be caused the wasting of resources by bursting by freezing.In order to prevent that this phenomenon from taking place, generally be to adopt the binding heat insulating material on top, water pipe ground or assemble a measure such as keeping warmth space with brick at present, these measures not only bother but also not attractive in appearance, but also often because temperature is crossed low ineffective; The otherwise address way is the outer water pipe of emptying chamber, stops using, and brings inconvenience in the use to the user like this.

The utility model content

Technical problem to be solved in the utility model is to propose a kind ofly to guarantee that outdoor water pipe can normally use and can effectively prevent the antifreeze water pipe of its bursting by freezing winter.

Technical scheme provided by the utility model is: a kind of antifreeze water pipe, include a vertical water pipe of placing, and this antifreeze water pipe also includes an end pipe, and the upper port of described end pipe is threaded with the water pipe lower port; The top of described water pipe side is provided with delivery port, and the bottom is provided with return pipe, and the two-port of this return pipe communicates vertically with water pipe; The upper port of described water pipe is provided with upper end cover, is provided with through hole in the middle of this upper end cover; The side of described end pipe is provided with water inlet, and its lower port is provided with bottom end cover; Described water pipe inside is provided with pull bar, piston-type switch, and this pull bar one end passes the through hole of upper end cover, and the other end links to each other with piston-type switch, and the lower end of this piston-type switch is provided with rubber stopper.

Further, described end pipe diameter is greater than the water pipe diameter, and described rubber stopper diameter equals end pipe diameter.

Further, be provided with spring in the described end pipe, this spring one end in contact rubber stopper, other end contact bottom end cover; Described pull bar lower end is provided with packed-piston, and the sealing piston is fixedlyed connected with pull bar.

Further, the lower end inwall of described water pipe is provided with the reducing pin that anti-piston-type switch drops.

The utility model has following advantage: simple in structure, install easily, and easy to maintenance; Be applicable to rural area and cities and towns outdoor environment in winter that the north is vast, avoid the water pipe from freezing crack phenomenon to take place, reduce unnecessary loss; Easy and simple to handle, also can be used as the valve of water pipe, convenient to use.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.

A kind of antifreeze water pipe as shown in Figure 1 includes a vertical water pipe of placing, and also includes an end pipe 11, and the upper port of end pipe 11 is threaded with the water pipe lower port, and end pipe 11 diameters are greater than water pipe body 2 diameters; The top of water pipe body 2 sides is provided with delivery port 14, and the bottom is provided with return pipe 13, and the two-port of this return pipe 13 communicates vertically with water pipe body 2; The upper port of water pipe is provided with upper end cover 1, is provided with through hole in the middle of this upper end cover 1; The side of end pipe 11 is provided with water inlet 12, and its lower port is provided with bottom end cover 9; Water pipe inside is provided with pull bar 3, piston-type switch 6, these pull bar 3 one ends pass the through hole of upper end cover 1, the other end is provided with packed-piston 4, sealing piston 4 is fixedlyed connected with pull bar 3, packed-piston 4 contacts with piston-type switch 6, the lower end of this piston-type switch 4 is provided with rubber stopper 8, and rubber stopper 8 diameters equal end pipe 11 diameters; Be provided with spring 10 in the end pipe 11, these spring 10 1 end in contact rubber stoppers 8, other end contact bottom end cover 9; The lower end inwall of water pipe is provided with the reducing pin 7 that anti-piston-type switch drops.

When use in rural area or cities and towns, be embedded in this antifreeze water pipe the latter half underground, piston-type switch 6 is in normally off, presses handrail 15 downwards, and switch 6 promptly is in open mode, as shown in Figure 1, this moment, water inlet 12 was communicated with switch 6, and water flows into from water inlet 12, through switch 6 inside, enter into the top of body 2 inner carriers by return pipe 13, discharge by delivery port 14 at last.

As shown in Figure 2, rely on the effect of spring 10, rubber stopper 8 is bounced, block the lower port of body, close the passage of water inlet 12 and switch 6, water just can not enter in the body 2 again.Still have part water in the body 2 this moment, upwards spurs handrail 15 and mention piston 4, just can be discharged the water in the body 2 by delivery port 14, reaches antifreeze purpose for this reason.
