Description
本発明は、弁体収容部を内側に設けてあるコック本体に、前記弁体収容部に連通するガス流入流路とガス流出流路とを略同芯状に設け、前記弁体収容部に収容してある弁体の、前記ガス流入流路又は前記ガス流出流路の流路軸芯に略直交する方向の回動軸芯周りでの回動で、前記ガス流入流路と前記ガス流出流路との連通状態を調節自在に構成してあるガスコックに関する。 The present invention provides a cock main body provided with a valve body housing portion on the inside thereof, and a gas inflow channel and a gas outflow channel communicating with the valve body housing portion are provided substantially concentrically. The gas inflow channel and the gas outflow are rotated by rotating the valve body accommodated around a rotation axis in a direction substantially orthogonal to the channel axis of the gas inflow channel or the gas outflow channel. The present invention relates to a gas cock configured such that a communication state with a flow path is adjustable.
上記ガスコックは、ガス流入流路側をガス供給用の固定配管に接続固定しておいて、ガス器具などをガス流出流路側に適宜接続できるように設けてあり、ガス流入流路とガス流出流路との連通状態を調節し易い姿勢で固定配管に接続固定しておくことが望ましい。
従来の上記ガスコックでは、弁体と同軸芯周りで一体に回動操作自在なハンドルをコック本体の外側に設けて、このハンドルの回動操作で弁体を一体に回動させて、ガス流入流路とガス流出流路との連通状態を、例えばガス流入流路とガス流出流路とが連通している連通状態や、連通を遮断している遮断状態に調節自在に構成してある(例えば、特許文献1参照)。
The gas cock is provided so that the gas inflow channel side is connected and fixed to a fixed pipe for gas supply so that a gas appliance or the like can be appropriately connected to the gas outflow channel side. It is desirable to connect and fix to the fixed pipe in a posture that allows easy adjustment of the communication state.
In the conventional gas cock, a handle that can be rotated integrally around the coaxial core with the valve body is provided outside the cock body, and by rotating the handle, the valve body is rotated integrally so that the gas inflow The communication state between the channel and the gas outflow channel is configured to be adjustable to, for example, a communication state in which the gas inflow channel and the gas outflow channel communicate with each other, or a blocked state in which the communication is blocked (for example, , See Patent Document 1).
このため、ガス流入流路とガス流出流路との連通状態を調節し易い姿勢で、ガスコックを固定配管に接続固定するにあたって、ハンドルの位置が固定配管周りのうちの回動操作し易い位置になるように、接続固定する必要があり、接続作業が煩雑化する欠点がある。
また、ねじ継手を介して固定配管に接続固定する場合は、ハンドルの位置が接続作業時に固定配管周りに移動し易いので、接続作業に熟練を要する欠点もある。
本発明は上記実情に鑑みてなされたものであって、ガス流入流路とガス流出流路との連通状態を調節し易い姿勢で、ガスコックを固定配管に接続固定するにあたって、簡便な接続作業で接続固定できるようにすることを目的とする。
For this reason, when the gas cock is connected and fixed to the fixed pipe in a posture in which the communication state between the gas inflow path and the gas outflow path can be easily adjusted, the position of the handle is set at a position that is easy to rotate around the fixed pipe. Thus, it is necessary to fix the connection, and there is a disadvantage that the connection work becomes complicated.
In addition, when connecting and fixing to a fixed pipe via a threaded joint, the position of the handle easily moves around the fixed pipe during the connection work, so there is also a drawback that requires skill in the connection work.
The present invention has been made in view of the above circumstances, and in a posture in which the communication state between the gas inflow channel and the gas outflow channel can be easily adjusted, when connecting and fixing the gas cock to the fixed piping, The purpose is to be able to fix the connection.
