    • The present invention relates to a pipe sealing cover which is easily and promptly coupled to an end of a pipe to be closely contacted with and supported by an inner wall not to be pushed or detached by strong fluid pressure or vibration and reduces the number of parts to lower manufacturing costs. The pipe sealing cover includes a close contact support portion in which a hollow portion formed in one body and having a closed upper portion and an opened lower portion is formed, a side portion close contact surface which can be closely contacted by being fitted to an inner wall of a pipe is formed at a lower outer wall, and a flange supported by an end of a pipe is formed at an upper outer wall; a pressing protruded portion protruded upward at an inner center of an upper surface of the close contact support portion to include a side pressed surface of an upper side wall and a downward-inclined surface of a lower side wall; and a cut portion disposed between an upper end portion of an internal diameter of the close contact support portion and an outer side of a lower end of the inclined surface of the pressing protruded portion.

    • PURPOSE: A water removing device for operation without stopping water supply is provided to carry out operations without stopping water supply by controlling the water supply for a required water pipe temporarily by shutting off the water flow in the water pipe by expansile and frictional forces caused by a tube type element inserted in the water pipe. CONSTITUTION: A water removing device includes a water removing part(1) to be inserted in a water pipe(21) to stop water supply for stopping the water supply and a clamping part(2) for inserting or withdrawing the water removing part from the water pipe, wherein the water removing part includes a guide jig(7) to be fixed to the water pipe, a fixing clamp(31) to be screwed with the guide jig, and a lifting clamp(16) connected to a lifting cylinder(15) for lifting in the fixing clamp, and a tube type clamp(18) is provided to the inner periphery of a through hole(17) of the lifting clamp to be retracted or expanded by high pressure air to selectively clamp the water removing part.
    • 目的:提供一种用于不停止供水的除水装置,通过以下方式临时控制所需水管的供水来暂停供水,从而不停止给水,从而通过以下方式产生的膨胀和摩擦力来关闭水管中的水流: 插入水管中的管型元件。 构成:除水装置包括插入水管(21)中以停止供水以停止供水的除水部分(1)和用于从水分离器中插入或取出除水部分的夹紧部分(2) 水管,其中所述除水部包括要固定到所述水管的导向夹具(7),与所述导向夹具螺合的固定夹具(31)和连接到所述提升缸体(16)的提升夹具(16) 15),用于提升固定夹具,并且将管式夹具(18)设置到提升夹具的通孔(17)的内周,以通过高压空气缩回或膨胀,以选择性地夹紧除水部分 。

    • 본 고안은 배관 핏팅용 플러그의 확장판 확장장치에 관한 것이다. 본 고안에 따른 상기 확장장치는, 상기 확장판의 상부 표면과 접하는 원판부, 상기 원판부의 센터 영역에 형성되어 있으며, 회전하는 플러깅 머신에 연결되는 돌출부, 상기 원판부를 관통하여 형성되어 있으며, 상기 돌출부를 기준으로 하여 원판부의 곡률 반경에 따라 형성되어 있는 복수의 외측 장홀 및 내측 장홀로 구성되어 있다.
      본 고안에서는 상기 외측 장홀 및 내측 장홀에 볼트 및 안내돌기를 삽입하여 상기 확장판과 확장장치를 단단히 체결한 상태에서 상기 확장장치를 이용하여 확장판을 확장시킴으로써, 확장판을 보다 안정적으로 확장시킬 수 있으며, 상기 확장장치를 이용하여 확장판을 확장시킨 후에는 상기 확장판과 확장장치를 체결하고 있던 볼트를 풀어준 다음에 상기 확장판으로부터 확장장치를 분리해 냄으로써, 장비 오류나 장비 작동 미숙으로 인한 확장장치의 낙하 위험을 최소화한다.
