Description

무퇴수 부동전{A nonfreezing valve}A nonfreezing valve

본 발명은 무퇴수 부동전에 관한 것으로, 보다 상세하게는 부동전의 관체 하부에 퇴수를 저장 할 수 있는 회수탱크를 설치하고 상기 퇴수탱크 내부에는 승강손잡이와 연결설치된 퇴수받이 및 배출용 판형피스톤을 설치하여 동절기에 수도 사용후 밸브를 잠군뒤 승강손잡이를 눌러 가압시키면 퇴수받이 및 배출용 판형피스톤이 하강하면서 관체 내부에 남아 있던 물이 퇴수탱크로 유입저장되고, 밸브를 개방시켜 물을 사용할때는 하강되어 있던 승강손잡이를 끌어올린뒤 밸브를 개방시킴으로서 퇴수탱크의 물이 밸브구멍을 통하여 배출되는 물과 함께 외부로 배출되게 함으로서 종래 부동전과는 달리 땅속으로 퇴수되는 물이 전혀 없어 절수효과가 매우 뛰어나고 튀소공이 없어 땅속의 이물질이 관속에 유입될 염려가 전혀 없어 위생적인 사용이 이루어지게 하기 위한 것이다.The present invention relates to a non-water-repellent anti-freeze, and more specifically, to install a recovery tank that can store the discharge in the lower part of the pipe before the float and to the discharge tank and the discharge plate and discharge plate plate connected to the lifting handle is installed After using the water in winter, close the valve and press the lifting knob to pressurize it. Then, the discharge tray and discharge plate piston descend, and the water remaining inside the pipe flows into the discharge tank, and when the water is used by opening the valve, the water drops. By raising the lifting handle and opening the valve, the water of the discharge tank is discharged to the outside together with the water discharged through the valve hole.Therefore, there is no water discharged into the ground unlike the conventional floating operation. There is no fear that foreign substances in the ground will flow into the pipe. It intended to be.

주지된 바와 같이 부동전이란 동절기에 관체 내부에 남아있던 물이 밸브를 잠금과 동시에 땅속으로 자동배수되게 하여 동파를 예방 할 수 있게한 수도밸브를 말하며, 통상 핸들을 돌려 밸브를 잠그면 부동전의 관체 내부에 남아있던 물이 퇴수공으로 자동 배수되고, 핸들은 반대로 돌려 밸브를 개방시키면 밸브에 의해 퇴수공이 막히면서 물이 배출될 수 있도록 구성되어 있다.As is well known, floating power refers to a water valve which prevents freezing by automatically draining water into the ground at the same time as the valve locks the water in winter. The water remaining in the drain is automatically drained to the drain hole, the handle is configured to allow the water to be discharged while the drain hole is blocked by the valve by opening the valve reversely.

그러나 상기한 종래의 부동전은 다음과 같은 큰 문제점이 따를 수밖에 없는 구조적 문제점을 안고 있다.However, the conventional anti-freeze has a structural problem inevitably accompanied by the following large problems.

즉, 밸브를 잠꿨을때 부동전의 관체내부에 남아있던 물이 퇴수공을 통해 땅속으로 퇴수되기 때문에 부동전이 동파되지 않는 잇점이 있는 반면에 귀중한 수자원의 낭비가 극심하게 되고, 또 퇴수공을 통하여 땅속의 이물질, 흙등이 부동전의 내부로 유입될 염려가 커서 비위생적인 문제점이 따를 수밖에 없었다는 것이다.In other words, when the valve is shut off, the water remaining in the inner tube of the anti-freeze is discharged into the ground through the sewage hole, so that the anti-freeze does not freeze, while the waste of precious water resources is severely lost. Foreign matters, soil, etc. were likely to flow into the interior of the anti-freeze, so there was no unsanitary problem.

따라서 본 발명은 전술한 종래의 제반문제점을 감안하여 안추된 것으로, 특히 부동전의 상단에 위치하는 핸들은 밸브개폐용 회전핸들을 중심으로 퇴수받이 및 배출용 판형피스톤을 작동시키는 승강손잡이를 설치하되, 상기 밸브 개폐용 회전핸들과 승강손잡이는 결합되어 있을때는 함께 회전하여 밸브 개폐가 가능하게 되고, 밸브를 잠군뒤 승강손잡이를 가압하여 하강시키면 부동전 내부의 물이 회수탱크 내부로 자동으로 모아지게 되어 땅속으로 배출되는 퇴수가 전혀 없게 되며, 밸브를 개방시킬때는 하강시켰던 승강손잡이를 다시 끌어올려 밸브개폐용 회전핸들에 승강손잡이가 결합된 상태에서 회전시키면 퇴수탱크에 들어 있던 퇴수가 부동전의 관체내부로 재유입됨과 동시에 밸브를 통하여 유입되는 물이 배출되게 되어, 절수효과 극대화와 위생적인 사용이 이루어질수 있는 무퇴수 부동전을 제공하려는데 그 목적이 있는 것이다.Therefore, the present invention has been conceived in view of the above-mentioned conventional problems, in particular, the handle located at the top of the float before installing the lifting handle for operating the discharge receiving and discharge plate-shaped piston centered on the rotary handle for opening and closing the valve, When the valve opening and closing handle and the lifting handle is combined, the valve can be opened and closed by rotating together. When the valve is closed by pressing and lowering the lifting handle, the water inside the float is automatically collected into the recovery tank. There is no discharge of water into the ground, and when the valve is opened, the lifting handle that has been lowered is pulled up again and rotated while the lifting handle is coupled to the valve opening / closing rotary handle. At the same time, the water flowing through the valve is discharged to maximize the water saving effect. Mutoe can provide a wealth of coins used in the production of haryeoneunde will be achieved with a purpose.

The connecting water pipe 9 is installed so that the lower part of the pipe 2 is connected, and the lifting handle 5 is coupled to the valve opening / closing rotation handle 6. At this time, when the discharge tank (3) is closed by the discharge tray and the discharge plate-shaped piston (4)> by turning the lifting knob (5) to raise the valve body (7), the closed manual (10) opens and water is opened. It is configured to be discharged to the outside through the connecting water pipe (9) and the pipe (2).

미설명 부호 11은 퇴수용 구멍, 12는 오링, 13은 통수용 홈, 14는 밸브체 지지용 나사돌부, 15는 배출꼭지, 16은 망체, 17,18은 패킹, 19는 캡이다.Reference numeral 11 is a drainage hole, 12 is an O-ring, 13 is a water supply groove, 14 is a threaded portion for supporting the valve body, 15 is a discharge faucet, 16 is a mesh, 17, 18 is a packing, 19 is a cap.

이와 같이 구성된 본 발명은 부동전을 사용후 밸브를 잠그면 퇴수탱크(3)를 제외한 관체(2) 내부 및 연결수관(9)의 내부에 미처 배출되지 못한 물이 차있게 되는데, 이 상태에서 승강손잡이(5)를 가압시키면 승강손잡이(5)와 관체형태로 된 축(51)으로 연결설치된 퇴수받이 및 배출용 판형피스톤(4)이 하강하면서 관체(2) 내부에 차있던 물이 퇴수탱크(3) 내부로 유입되어 저장됨으로써 동절기에 관체의 동파가 예방되게 된다.According to the present invention configured as described above, when the valve is closed after the use of the floating power, the water that is not discharged in the inside of the pipe body 2 and the connection water pipe 9 except the discharge tank 3 is filled. (5) When the pressurizing member (5) is pushed down and the discharge tray and discharge plate-shaped piston (4) installed connected to the lifting shaft (5) and the shaft (51) in the tubular form, the water filled in the tubular (2) is discharged tank (3). ) By entering and storing inside, the freezing of the tube is prevented in winter.

또 물을 사용하기 위해 밸브를 개방시킬때는 하강되어 있던 승강손잡이(5)를 상승시켜 승강손잡이(5)와 밸브개폐용 회전핸들(6)이 결합되게 한 상태에서 승강손잡이(5)를 상승시키게 되면 퇴수탱크(3) 내부에 저장되어 있던 퇴수가 다시 관체 내부로 공급되고, 밸브개폐용 회전핸들(6)과 결합된 승강손잡이(5)를 돌려 밸브체(7)를 개방시키면 수공(10)과 연결수관(9)을 통하여 수도꼭지로 배출되게 됨으로서 퇴수의 재사용이 가능해 지게 되는 것이다.In addition, when the valve is opened to use water, the lowering lift knob 5 is raised to raise the lift knob 5 while the lift knob 5 and the valve opening / closing rotation handle 6 are coupled to each other. When the discharged water stored in the discharge tank 3 is supplied to the inside of the pipe again, turning the lifting knob 5 coupled with the valve opening / closing rotation handle 6 to open the valve body 7, And by being discharged to the faucet through the connecting water pipe (9) will be able to reuse the discharge.

따라서 본 발명에서의 핵심사항은Therefore, the key points in the present invention

첫째, 별도의 퇴수탱크로 인해 땅속으로 유실되는 물의 낭비를 예방 할 수있게 되고,First, it is possible to prevent the waste of water lost to the ground due to a separate discharge tank,

둘째, 밸브개페용 회전핸들(6)과 승강손잡이(5)가 별도 구성되어 설치되되 밸브 개폐시에는 반드시 결합된 상태로 조작하여야 하며,Second, the valve opening rotary handle 6 and the lifting handle (5) is installed separately, but must be operated in a coupled state when opening and closing the valve,

셋째, 밸브가 잠긴뒤에 승강손잡이(5)를 눌러 하강시켜 퇴수탱크를 개방시킴으로써 물의 유실이 전혀 없이 퇴수가 이루어지게 되고, 따라서 동절기 동파예방이 확실하게 이루어질 수 있게 된다는 점이다.Third, after the valve is locked, the elevator knob 5 is pushed down to open the discharge tank so that water can be discharged without any loss of water, thus preventing freezing in winter.

한편, 본 발명은 위에 설명한 (밸브개폐시) 핸들을 회전시키는 구성외에 핸들을 원터치식으로 눌러 가압시키는 방식으로도 가능하며, 따라서 이러한 변형은 모두 본 고안의 권리범위에 포함된다 하겠다.On the other hand, the present invention is possible in the manner of pressing the handle in one-touch manner in addition to the configuration of rotating the handle (when the valve opening and closing) described above, and thus all such modifications will be included in the scope of the present invention.

이상 살명한 바와 같이 본 발명은 부동전의 하부에 퇴수탱크를 설치하여 땅속으로 버려지는 물의 손실을 예방함으로써 절수효과가 극대화 되고 또 땅속의 이물질이나 세균, 흙등이 유입될 염려가 없어 위생적으로 사용 할 수 있는 매우 유용한 발명인 것이다.As described above, the present invention is installed in the lower part of the anti-freeze tank to prevent the loss of water to be discarded into the ground to maximize the water saving effect and there is no fear of foreign substances, bacteria, soil, etc. in the ground can be used hygienically. It is a very useful invention.
