Abstract

PURPOSE: A water-saving way apparatus is provided to prevent danger of frozen rupture at winter season caused by freezing of water pipe by applying specific device to be automatically opened/closed according to outer temperature. CONSTITUTION: The apparatus comprises a core(8); bi-metallic alloy springs(9) at upper/lower ends of the core(8); cavities to be opened/closed(6); water-passing holes(7,7-1) to discharge water. The core, the springs and the cavities are subsequently interposed to form an integrated product. The core and the cavities coupled together pass the water through. The holes(7,7-1) preferably have about 1.5mm of diametric size. The bimetallic spring can retain a standard condition at 2 deg.C but when lowering the temperature below 2 deg.C, the spring reacts to lead spring force in opposite direction of water-outlet.

Description

Water-saving water pipe freeze arrester {Frost proof faucet}

The present invention relates to a freeze arrester of water pipes in detail to automatically close the water pipe in the underground pipe portion unaffected by the outside air when the water pipe valve is closed in winter, so that the water remaining in the water pipe exposed to the ground is automatically discharged It relates to a freeze blocker to prevent freezing of the water pipe due to freezing of the winter water pipe.

Since water pipes installed outdoors are used with parts of the water pipes exposed to the ground, water inside the water freezes at the site directly affected by the outside air in winter, causing water pipe rupture or damage to the valve.

In order to prevent this, a valve is installed in the ground, and a method of using an underground valve in winter or insulating the exposed part of the outside air is used to insulate it, and as a separate device, the valve of anti-freeze according to Korean Utility Model No. 0169822 as a separate device. , Freeze and freeze protection water supply device according to the Republic of Korea Utility Registration No. 0225771, anti-freeze structure according to the patent No. 0158427 has been proposed. The basic principle of these devices is to install a separate opening and closing valve at the inlet of the water pipe connected to the faucet so that it can be locked in winter, and to form a separate outlet for discharging water between the valve and the faucet opening and closing valve It is easy to forget valve operation and complicated operation because the opening and closing of the valve is done manually, and it is possible to use long length valve stamp separately for opening and closing operation of raw water valve or to open and close the water separately from faucet opening and closing valve. There is a problem in that the configuration is complicated and inconvenient to use such as to install a valve. In addition, if the muddy water is introduced into the on-off valve during the construction of sand or water can not be used. The present invention is a product that completely complements the advantages.

The present invention solves the problems of the conventional water pipe freeze protection mechanism or apparatus, and proposes a water pipe freeze prevention mechanism having a structure that can open and close the raw water inlet automatically according to the temperature by a mechanism simply attached to the water pipe passage. do.

Our country is also a water shortage country recognized by the UN. Leakage caused by freezing waves is a huge amount of water in Korea. In addition to being a huge economic loss, the damage caused by freezing waves is enormous, forcing consumers to use water in a timely manner. The present invention is a product that can achieve not only the function of preventing the freeze, but also water saving effect of blocking the leakage.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is for illustrating the basic configuration of the present invention, Figure 2 is a view showing a combined state of the present invention, the present invention is a bimetal alloy spring (9) and opening and closing hole 6 in the upper and lower portions of the mandrel (8) The sequential insertion is inserted and coupled to the mandrel and fixed integrally, and is configured to allow the flow of the mandrel and its opening and closing hole by a rotational motion according to the temperature change of the bimetal alloy spring, and a through-hole penetrating each up and down (7) (7-1) is a construct which acts as water drainage. The drip ball serves to continuously discharge the water in the main body and the upper water pipe when opened with a fine hole of about 1.5 mm.

According to the present invention, the spring force is determined so that the bimetal alloy spring is kept in the normal state, that is, the opening and closing hole in the standard state at 2 ° C or more, and the inlet opening is maintained. Characterized in that the change in the spring force occurs so that the direction of action of the spring force is reversed.

The bimetal alloy spring is manufactured to change or increase the modulus of elasticity at a specific temperature, for example, 2 ° C. or less, so that when the outside air temperature is reduced to 2 ° C. or less, the spring force acts in the opposite direction to the drain port, thereby opening the drain. Here, the example of 2 ℃ is not to designate a specific region from 0 ℃ to 2 ℃, but to explain that the spring responds to the rotational movement even at the minute temperature change.

3 and 4 are for explaining the specific operating state of the present invention when applied to the present invention using a bimetal alloy spring molded to maintain a balanced state at 2 ℃ or more and increase the modulus of elasticity below 2 ℃ FIG. 3 shows the operating state of the construct when the outside temperature is maintained at 2 ° C. or higher, and FIG. 4 shows the operating state of the valve construct when the outside temperature drops below 2 ° C. or when the faucet valve is opened at 2 ° C. or lower. It is shown.

Fig. 3 shows a state where the outside air temperature is 2 ° C or more or the faucet valve is opened, and shows the standard state of the bimetal spring. When the outside air temperature is 2 ℃ or more, the inlet port is always kept open to close the water draining hole so that the water outflow by the water draining hole is blocked, and the water obtained through the inlet flows without restriction through the water supply hole.

4 shows that when the outside air temperature drops below 2 ° C, the spring is contracted by the rotational movement of the bimetal alloy spring, and at this time, the spring is pushed upward by pushing the mandrel 8 to the shaft to open the drain hole. The water is drained through.

Each of the above examples can perform the same function using a bimetal spring designed to increase the modulus of elasticity when the outside temperature is below 2 ° C, or when using a bimetal spring designed to reduce the modulus of elasticity when the outside temperature is below 2 ° C. Will be.

The present invention is installed by simply attaching on the water pipe line, the opening and closing is automatically made according to the outside temperature is very easy to use, has the effect that can be used continuously without failure.

In addition, the present invention is a product that is excellent in water saving effect to block the inflow of a large amount of water due to freezing, as well as the effect of freezing at the present time the water saving movement is required largely.
