종래에는 출원인이 출원번호 제80-13703호로 선출원한 수도미터기 관접구가 있었으며, 이 수도미터기 관접구는, 수도미터기를 수도관에 관접하는 곡간의 내부에 삽통한 지지관의 하단부에 변공을 개폐하는 밸브가 스프링으로 탄설된 밸브관이 관접하여 밸브관을 수도관의 상단부에 관접하고 곡관을 지지관에 체결하는 체결나사의 하단부에 원통형의 여과망을 형성하여 여과망의 하단부에 밸브를 눌러 개방시키는 +자형의 돌기를 형성하며 손잡이가 형성된 나사의 두부에는 배기공이 상단부에 배기실을 여과망과 상하로 연통되게 형성하며 배기실 하부에 형성된 밸브실에 물에 뜨는 배기밸브를 수납하여서 나사를 지지관의 나사부에 나착 하여서 된 것이 있었다.Conventionally, there has been a water meter fitting port which is filed by the applicant with the application number 80-13703, which is a valve for opening and closing the valve at the lower end of the support pipe inserted into the grain stem which is in contact with the water pipe. The valve tube, which is installed with a spring, comes into contact with the tube, and the tube is connected to the upper end of the water pipe, and a cylindrical filter net is formed at the lower end of the fastening screw for fastening the curved pipe to the support tube. The exhaust hole is formed in the head of the screw is formed in the head of the upper and upper communication with the filter net in the upper end of the screw, and the exhaust valve is floating in the valve chamber formed in the lower part of the exhaust chamber to screw the screw into the screw portion of the support tube There was something.

상기한 수도미터 관접구에서는 밸브관에 스프링 탄설된 밸브를 상부로 체결되는 나사를 나착할때 여과망의 하부로 형성되는 돌기가 밸브를 눌러 변공을 개방하고 여과망을 분리했을 때 밸브는 스프링에 의해 탄발되어 변공을 개방할 수 있도록 되어 있으며, 여과망에 의해 수도물에 혼입되어 있는 이물질을 제거함과 동시에 여과망 상부의 밸브실에 수납되는 밸브가 물에 떠 수도물속에 발생된 공기를 제거할 수 있게한 것이다.In the above water meter tube opening, when the screw which is fastened to the valve pipe spring-tightened to the valve tube is attached, the protrusion formed at the lower part of the filtering network presses the valve to open the valve opening, and the valve is released by the spring It is to be able to open the toilet, it is possible to remove the foreign matter mixed in the tap water by the filter net and at the same time the valve housed in the valve chamber of the upper filter net floats to remove the air generated in the tap water.

그러나, 상기한 관접구는 밸브가 스프링에 의해 탄설되어 있어 오랜기간 사용할 경우 스프링의 탄성력이 감쇠되어 변공 개폐기능이 저하되어져 여과망에 제거된 이물질을 제거할 때 변공을 통해 물이 누수되어지는 문제점이 있고, 여과망을 분리하였을때 출수관의 수도물이 역순환되어 이물질을 제거하는 시간동안 수도물이 출수관을 통해 빠져나와 수도물을 낭비하게되는 문제점을 가지고 있다.However, the above-described pipe contact has a problem in that water leaks through the valve when removing the foreign matter removed in the filter net due to the deterioration of the opening and closing function of the spring due to the damping of the elastic force of the spring when used for a long time. In addition, when the filtering network is separated, the tap water of the outlet pipe is reversely circulated so that the tap water is discharged through the outlet pipe during the time of removing the foreign matter, and wastes tap water.
