Cold air delay cutoff structure of floating water supply

The present invention relates to a cold air delay blocking structure of an antifreeze water supply, and more specifically, in an antifreeze water supply with a water supply pipe connected to an underground water supply pipe, external cold air is conducted through the water outlet, which is a faucet point exposed to the outside. It relates to a cold air delay blocking structure of an antifreeze water supply that is capable of preventing damage due to freezing and freezing by delaying or converting the temperature to room temperature.

In general, water pipes supplied from a water source to a customer are buried underground, and a water pipe installed underground is connected to a water meter at the customer's home, and a water pipe that has passed through the water meter is connected to the customer's point of use, and a floating water supply installed outdoors is installed. It is done.

Normal water pipes exposed as described above are provided with an insulating material or insulating material outside the water pipe so as not to freeze, and the valve installed in the ground is locked when the control lever of the floating water supply on the ground is closed by installing an opening and closing valve in the ground. An anti-freezing water supply is used that is configured to prevent freezing by allowing water in the pipe to be exposed to the ground by opening the discharge hole provided in the side pipe to be discharged to the ground through the discharge hole.

The general antifreeze water supply is exposed to the ground, and various types of prior art are known in order to prevent freezing and freezing of the inside of the antifreeze water supply due to external temperature in winter.

For example, in the Korean Utility Model Publication No. 20-0335081 (published date; 2003.12.01.), “A floating valve Hawoojeong (1) is installed at the connection part of the underground water supply pipe (8) and the water supply main (2). , In the floating valve housing (1), a valve seat (12) for opening and closing the flow path by raising and lowering the valve body (10) is rotatably installed.

As described above, in Registration Utility Model Publication No. 20-0335081, a drainage body to which a valve stem is fastened is coupled between a floating valve housing and a key protection pipe, but the drainage body is connected to the drainage hole when the valve stem rises. It has an inner channel; One end of the drainage body is provided with a freeze-preventing floating water supply column, which specifies that a drainage valve with an internal part for preventing backflow of discharged water from the outside is provided, but the structure is complex and is provided separately at the bottom of the floating water supply. There is a drawback of being exposed to the outside, and there is a problem that it is difficult to install and disassemble because a water supply bottle that is exposed to the outside is provided, and there is a problem that the price competitiveness is lowered due to an increase in manufacturing cost, and when the external coolant passes through the faucet to the inside of the water supply valve There is a problem in that there is no structure that can prevent any damage caused by freezing, so that it is exposed to freezing waves due to cold air as it is.

In addition, as above, in Registered Utility Model Publication No. 20-0328686, a three-way cock installed on one side of the hydrant is installed, and a drainage hole and a drainage channel are separately connected to the cock, and a drain pump is connected with a pipe, and when it is necessary to prevent freezing, The water supply is blocked using the drainage three-way cock, and the drain of the cock is opened.After opening all the hydrants in the following order, a manual or electrically controlled drainage pump connected to the drainage of the drainage three-way cock is provided. Thus, the water inside the water pipe, which may be freezing, passes through the drain of the three-way cock for drainage, and then discharges through the pump drain, thereby preventing freezing of the water supply pipes, which prevents freezing of water pipes. There is a problem that a separate piping line must be provided for this, and there is a problem that an installation structure must be provided separately,

In addition, there is a problem that price competitiveness is lowered due to an increase in manufacturing cost, and there is no structure to prevent damage due to any freezing when external cold air passes through the faucet to the inside of the water supply valve, so it is exposed to freezing waves by cold air as it is. There is this.

In addition, as described above, in Registered Utility Model Publication No. 20-0482925, a water supply pipe provided in the water pipe, an opening/closing valve on the fun side of the water supply pipe, an insulating material surrounding the opening/closing valve, and an outer case It is equipped with a cover and a lower cover inside the outer case, but there is no structure that can block the cold air conducted from the outside to the inside through the faucet, so freezing and damage may occur due to the cold air in winter. In addition, the method of blocking the upper side of the hydrant by covering it outside only prevents the inflow of cold air from the hydrant, but there is a problem that it cannot block the cold air conducted into the water supply valve through the faucet, so it is a structure that can prevent damage due to freezing. There is a problem in that it is exposed to freezing waves caused by cold air as it is because there is no.

In addition, as described above, in Registration Utility Model Publication No. 20-0482925, the sliding tube body with elastic packing is inserted into the outer circumferential surface of the protection tube buried in the ground, and the sliding tube body is configured to slide the main surface of the protection tube up and down according to the elevation of the ground. Although the faucet is equipped with a freeze prevention device, the structure is complicated and it has the disadvantage of having to be separately provided at the bottom of the floating hydrant, and there is a problem that it is difficult to install and disassemble because a water supply column that is exposed to the outside is provided, and the manufacturing cost is high. There is a problem in that the price competitiveness is decreased due to the increase, so that improvement measures are required.

The present invention was conceived to solve the conventional shortcomings as indicated above, and the cold air is at room temperature while delaying and blocking the conduction of cold air that is conducted to the inside through the water outlet around the faucet exposed to the outside of the floating water supply. It is equipped with a cold air delay means that can be converted into a freeze to prevent damage and freezing due to freeze.

In addition, the cold air delay means is provided to delay and block not only insulation but also cold air conduction by an insulating material provided on the outer circumferential surface of the internal water supply pipe of the floating water supply, and to extend the length of the connection pipe inside the insulating material to secure the cold air conduction delay time. ,

In particular, the main purpose of this is to provide a cold air delay blocking structure of the floating water supply so that the cold air conducted through the connection pipe of the cold air delay means can be delayed and converted into warmth by using the internal insulation of the non-free water supply.
