WATERCONTROL VALVE REPLACEMENT METHOD WITHOUT SUSPENSION OF WATER SUPPLY

摘要

When you cut the pipe without singular of fluid in the pipe, the cleavage site can be formed accurately, This one can unceasingly tube cutting and valve insertion method are disclosed for installing the valve in the cutting area. Unceasingly be disclosed tube cutting and closing the valve insertion method is to provide guidance to the upper surface of the arc-shaped upper and upper guide portion is constituted in accordance with the central longitudinal slot is formed, while the closing member on one side of the sliding guide selectively opening and closing the inlet Add to surround the upper sealing the tube guider is formed at the same time to secure the upper sealing guider fixed stage; Lower seal guider fixing step for fixing the lower seal in the lower portion of the tube and the upper sealing guider guider is installed; The upper and lower seal guider doedoe divided into a plurality of closed rotating in the circumferential direction on the outer surface of the guider exchange installation, for which a rotation is input through the input port, the cutting edge having a cutting tool to the distal end outer peripheral surface is provided, the rotation pivoting dog stationary pipe length comprising freely rotatably installed in the vertical direction of the direction; Operating the cutting tool to rotate about the pivot while being guided along a slot cutting groove the cutting tool to cut the tube forming step of forming a cut groove by the rotation; Remove the pivot for the upper sealed in airtight guider guider and lower, and separation steps for meeting to seal the inlet through the closing member; Is introduced into the tube through the cutting groove is selectively brought into close contact with the inner circumference of the pipe and a valve having a valve disc for opening and closing the tube characterized in that it comprises the steps of inserting a valve mounted to the upper seal guider. ;
