摘要： PROBLEM TO BE SOLVED: To provide a water discharge instrument having a stable operation characteristic having a temperature control valve for controlling mixed water temperature by changing the mixing amount of water and hot water by changing the opening ratio of a water side opening and a hot water side opening by moving a spool valve in the axial direction. SOLUTION: This water discharge instrument has a cylindrical housing 41, a water side opening 52 and a hot water side opening 54 for letting water and hot water flow in a mixture chamber 64, the spool valve 46 integratedly having a water side valve 48 and a hot water side valve 50, and a water side rear chamber 55 and a hot water side rear chamber 57 installed in the housing 41 and on the rear sides of he water side valve 48 and the hot water side valve 50. A short-circuiting cannel 61 for directly communicating the water side rear chamber 55 with the hot water side rear chamber 57 for balancing the pressure in the chambers 55, 57 is installed in the temperature control valve 36.

摘要： PROBLEM TO BE SOLVED: To suppress lowering of opening regulation operation and the opening indication function of a valve due to lodging of sedimentary sand and pebbles between an indicator and the upper surface of a case body. SOLUTION: This valve is formed such that an input shaft 7 is relatively rotatably held in a fit-in state and an indicator 15 to index a valve opening through rotational movement linked with rotation of the sleeve 6 is fixed at the sleeve 6 rotatably supported at the cover 3 of a case body. In this case, the indicator 15 consists of an annular disc having only the through-hole 15b, formed in its central part, of the input shaft 7 and a position indication part corresponding to a scale 14 is printed and formed on the upper surface of the indicator 15 consisting of the annular disc. Further, a dust seal 18 is provided to seal a gap S provided between the indicator 15 and the upper surface of the cover 3.

摘要： PROBLEM TO BE SOLVED: To separately install a valve body from a drive source for opening/ closing the valve by connecting a drive shaft of a rotation drive for opening/ closing the valve to a valve stem of the valve via a flexible connecting rod. SOLUTION: A valve 2 is provided on the way to a pipe 1, the valve 2 has a valve stem 4 projected from a valve casing 3, a handle for opening/closing operation is installed in the tip of the valve stem 4, and a pipe whole body including the valve 2 is covered with a heating means 5 such as heat insulating material. On the other hand, the rotation drive 11 for opening/closing the valve 2 is provided with a mechanism rotating the drive shaft 12 by an air pressure or a motor and the drive shaft 12 and the valve stem 4 of the valve are connected together by a flexible connecting rod 21. This constitution can improve the freedom degree of the installation of the valve 2 and the rotation drive 11. This constitution can also respond to the failure quickly.
