Description

잠금 장치가 부설된 수도계량기용 개폐밸브.{omitted}Opening and closing valve for water meter with locking device. {Omitted}

본 발명은 수도계량기용 개폐 밸브에 관한 것으로, 특히 필요시 수돗물 공급을 중단, 지연시킬 수 있는 잠금장치를 개폐밸브 회동손잡이 일측에 부설시키고, 장기간 사용시에도 수돗물 공급량이 일정하도록, 고무패킹을 사용하지않는 볼 밸브를 장착시키고, 수도관 연결시 단부측 확관 작업 없이 바로 연결될 수 있도록 하여 수도관 연결작업이 간편하도록 한 잠금 장치가 부설된 수도계량기용 개폐밸브에 관한 것이다.The present invention relates to an on / off valve for a water meter, and in particular, a locking device for stopping and delaying tap water supply is provided on one side of the on / off valve rotation knob, so that the tap water supply is constant even in long-term use, and does not use rubber packing. It relates to an open / close valve for a water meter which is equipped with a ball valve which is equipped with a ball valve which does not have a ball valve, and which can be directly connected without expanding the end side when the water pipe is connected.

종래에는 티(T)자형 손잡이가 부설된 앵글(니들)밸브를 장착하여 사용하므로서, 수도세 연체 또는 사용시기 미정 등으로 인해 개폐 밸브를 잠가야 하는 경우에도 잠금 장치가 없어 임의사용등 손실이 많았고, 통상의 앵글(니들)밸브는 수돗물 공급공을 밸브 축 단부측에 장착시킨 고무패킹으로 개폐시키므로서, 장기간 사용시 고무패킹이 닳아 마모되어 누수현상이나, 수돗물 공급량이 일정치 않게 되는 등의 문제점이 있었고, 수도관 연결시 수도관 단부측을 확관 시켜야만 연결시킬 수 있으므로 수도관 확관 작업에 따른 작업시간 증대와 제반 시설 및 장치가 소요되고, 수도관 확관부에 미세한 금이 가서 누수현상이 발생하는 등 많은 문제점이 있었다.Conventionally, since the angle (needle) valve with a tee (T) -shaped handle is mounted and used, even when the valve is to be shut off due to water overdue or undecided use time, there is no locking device. In general, the angle (needle) valve opens and closes the tap water supply hole with a rubber packing mounted on the valve shaft end side, so that the rubber packing is worn out and worn out over a long period of time, causing water leakage and a constant amount of tap water supply. In order to connect the water pipes, it is necessary to expand the end side of the water pipes, so that there are many problems such as increase of working time and various facilities and equipment due to the water pipe expansion work, and leakage of water due to fine cracks in the water pipe expansion pipe.

본 발명은 상기한 종래 기술이 갖고 있는 문제점을 해소코자 창출된 것으로, 수돗물 공급을 필요시 차단할 수 있도록 개폐밸브에 잠금 장치를 부설시키고, 수돗물 공급량이 장기간 사용시에도 일정할 수 있도록 하기 위해, 닳고 마모되는 고무패킹등을 사용하여 않고, 볼 밸브로 개폐작용 할 수 있도록 하고, 수도관 연결시 수도관 단부측을 확개 시키지 않고도, 수도관을 연결시킬 수 있도록 하는데 그 목적이 있다.The present invention was created to solve the problems of the prior art described above, to provide a locking device to the on-off valve so that the tap water supply can be cut off when necessary, in order to ensure that the tap water supply is constant even in long-term use, wear and wear The purpose is to enable the opening and closing action of the ball valve without using a rubber packing, and to connect the water pipes without expanding the water pipe end side when connecting the water pipes.

이러한 본 발명의 목적은, 수도계량기용 개폐밸브 상부측의 개폐부에 90°회전시키는 회동손잡이 외에 회동손잡이와 함께 90°회전하는 개폐공이 형성된 돌출환편을 형성하고, 개폐밸브 하우징 상부 일측에는 잠금공이 형성된 환돌편을 형성하여, 개폐밸브 잠금시 개폐부(6)의 돌출환편의 개폐공과 하우징의 환돌편의 잠금공 이 일치하여 자물쇠 등을 채울수있도록하고, 하우징 내부에는 개폐부의 회동 손잡이에 의해 회동 개폐되는 볼 밸브를 내설하여, 장기간 사용시에도 닳거나 쉽게 마모되지 않아 수돗물 공급량이 일정하도록 하고, 수도관 장착부에는 단턱부와 체결부를 형성하고 연결 수도관 외부 측에는 고무링과 와샤와 다수개의 볼이 장착된 체결구를 삽설시켜, 상기 하우징의 장착부에 수도관을 삽입하고 체결구를 체결시키면, 장착되므로서 이뤄지게된다.The object of the present invention is to form a protruding annular piece formed with opening and closing holes rotated by 90 ° with the rotation knob in addition to the rotation knob to rotate 90 ° in the opening and closing portion of the opening and closing valve for water metering instrument, the upper side of the opening and closing valve housing By forming an annular piece, when the opening and closing valve is locked, the opening and closing hole of the protruding annular piece of the opening and closing part 6 and the locking hole of the annular piece of the housing coincide with each other so as to fill a lock, etc. It is not worn out or worn out easily even after long-term use so that the tap water supply is constant.The water pipe mounting part is provided with a stepped part and a fastening part, and a fastener equipped with a rubber ring, washer and a plurality of balls is inserted at the outside of the connection pipe. When the water pipe is inserted into the mounting portion of the housing and the fastener is fastened, Will be done.
