- the present invention provides a housing having a divided structure in which a fluid pipe is fitted externally in a hermetically sealed manner, and a valve for inserting a valve body into a hole of a fluid pipe pierced in an unbroken state in the housing to control fluid in the pipe. And a flow control device having a flow valve.
- a housing split T-shaped tube having a divided structure is externally fitted to an existing fluid pipe in a sealed manner, and a work valve device (working A gate valve) and a piercing device (a piercing machine) are connected, and the piercing device pierces a fluid pipe inside the housing.
- a valve installation device work case, operating rod, jack mechanism
- a flow control valve valve case, gate valve
- the valve body of this flow control valve gate valve
- JP 2011-38584 A (page 18, FIG. 33)
- a working valve device is connected to an open end formed at an upper end of a neck portion of a split T-tube that constitutes a casing fitted to the fluid pipe, and further, the working valve device is further connected.
- a perforation device or, alternatively, a device for installing a flow control valve is connected to the upper end of the case, and this flow control valve is hermetically connected to the open end of the upper end of the neck of the housing. Therefore, the extension stroke of the cutter provided in the drilling device or the installation device of the flow control valve becomes long, and the drilling or valve body cannot be inserted at the designed position, resulting in a displacement, and the controllability of the fluid in the pipe cannot be maintained high. The problem had arisen.
- the present invention has been made in view of such a problem, and improves the positional accuracy of a hole formed in a fluid pipe in a housing and a valve inserted into the hole, thereby improving controllability of fluid in the pipe. It is an object of the present invention to provide a fluid control device that can reduce the size, weight, and cost of construction equipment such as a perforation device, a flow control valve installation device, a work valve device, and the like.
- a fluid control device of the present invention includes: A flow control valve comprising: a housing having a divided structure in which a fluid pipe is externally fitted in a sealed manner; a valve body and a valve housing that can be inserted into a hole of the fluid pipe that is bored in the housing in a non-flow state. And a fluid control device having at least: The housing has an open end for installing the flow control valve in the housing, and a neck with an opening for attaching and detaching a work valve device that can open and close the inside of the housing, A first sealing member formed in an annular shape is provided between a peripheral surface of the valve housing of the flow control valve and a peripheral surface of the neck portion closer to the fluid pipe than the opening.
- the opening portion for attaching and detaching the working valve device is provided at the neck of the housing, the mounting position of the working valve device can be closer to the fluid pipe, so that the piercing stroke is shortened.
- the displacement of the drilling can be minimized, and at the same time, the size, weight, and cost of construction equipment such as a work valve device and a drilling machine can be reduced.
- the annular first sealing member provided between the valve housing of the flow control valve and the peripheral surface closer to the fluid pipe than the opening of the neck allows the valve housing to move beyond the opening of the neck. Since the sealing state can be achieved, the opening and the open end can be simultaneously blocked in this sealing state.
- a second sealing member formed in an annular shape is provided between a peripheral surface of the valve housing of the flow control valve and a peripheral surface of the neck portion closer to the open end than the opening. It is characterized by: According to this feature, even if the first sealing member is temporarily separated from the inner surface of the neck when passing through the opening, the second sealing member can seal the inner surface of the neck at this time. The sealed state can be maintained until the insertion is completed.
- the peripheral surface of the neck is formed in a straight line in the insertion direction of the valve housing. According to this feature, not only can the valve housing be easily inserted along the inner surface of the neck formed in a straight line, but also the sealing state of the sealing member in contact with the peripheral surface can be stabilized.
- the valve housing of the flow control valve is provided with an openable / closable air vent hole at an upper end of the valve housing. According to this feature, since substantially all of the air in the valve housing can be discharged through the air vent hole formed in the upper end portion of the valve housing, the air in the valve housing may be compressed, leading to an unexpected accident. Not only can be avoided, but also corrosion of the valve housing can be suppressed.
- the opening of the neck is open in the direction of the fluid pipe. According to this feature, the working valve device to be attached to the opening can be extended in the direction of the fluid pipe, so that a mounting area for the working valve device can be easily secured.
- the housing is characterized in that it has an engaging portion that restricts the movement of the flow control valve installed in the housing in the circumferential direction. According to this feature, since the movement of the flow control valve in the circumferential direction with respect to the housing can be restricted by the engagement portion, the risk that the flow control valve moves due to the flow of the fluid in the pipe can be avoided.
- the housing is provided with a positioning portion for positioning the working valve device attached to the opening. According to this feature, since the work valve device can be accurately attached to the opening by the positioning portion, the function of opening and closing the casing by the work valve device can be maintained.

Description
流体管を密封状に外嵌する分割構造の筐体と、前記筐体内にて不断流状態で穿孔された前記流体管の孔部に挿入可能な弁体及び弁筐体を備えた制流弁と、を少なくとも有する流体制御装置であって、
前記筐体は、該筐体に前記制流弁を設置するための開放端部と、該筐体内を開閉可能な作業弁装置を着脱するための開口部とを備えた首部を有し、
前記制流弁の前記弁筐体の周面と、前記首部の前記開口部よりも前記流体管側の周面との間に、環状に形成された第1の密封部材が設けられていることを特徴としている。
この特徴によれば、筐体の首部に作業弁装置を着脱するための開口部を有していることで、作業弁装置の取付位置を流体管に近づけることができるため、穿孔ストロークが短くなり、穿孔の位置ずれを極小化でき、併せて作業弁装置や穿孔機などの施工用機材の小型化、軽量化、コストダウンを達成できる。また、制流弁の弁筐体と首部の開口部よりも流体管側の周面間に設けられた環状の第1の密封部材により、弁筐体が首部の開口部を超えた位置にて密封状態にできるため、この密封状態で開口部及び開放端部を同時に遮断することができる。したがって、この制流弁の弁体が流体管の孔部に挿入する際の支点が確実となり、ストローク長さを低減して弁体の位置精度を向上させ、管内流体の制御性を高めることができる。
この特徴によれば、第1の密封部材が開口部を超えるときに首部の内面から一時的に離間しても、このとき第2の密封部材が首部の内面を密封できるため、弁筐体が挿入し終えるまで密封状態を維持することができる。
この特徴によれば、直線状に形成された首部の内面に沿って弁筐体を挿入し易いばかりか、この周面に接する密封部材の密封状態を安定させることができる。
この特徴によれば、弁筐体の上端部に形成された空気抜き孔を介し弁筐体内の空気を略全量排出することができるため、弁筐体内の空気が圧縮されて不測の事故につながる虞を回避できるばかりか、弁筐体の腐食を抑制できる。
この特徴によれば、開口部に取り付ける作業弁装置を、流体管の管路方向に延設させることができるため、作業弁装置の取付領域を確保しやすい。
この特徴によれば、係合部により制流弁を筐体に対し周方向に移動規制できるため、制流弁が管内流体の流動により動いてしまう虞を回避できる。
この特徴によれば、位置決め部により作業弁装置を開口部に対し正確に取り付けることができるため、作業弁装置による筐体内の開閉機能を維持することができる。
