摘要： PURPOSE:To prevent over fastening of handle by feeling the encounter of a valve face with a proper closing contact force in the way of open valve operation. CONSTITUTION:A handle 4 of a stop valve 1 is rotary fastened to drive a screw member 3 so as to close contact a valve face 14 against a valve seat 7a. Here, a spring S for close contacting the valve face 14 against the valve seat 7a with a proper force is arranged in a valve thrust transmission system T between the drive screw member 3 and a valve body 12. With such arrangement, over fastening of handle, loosening of drive screw member due to vibration and leakage of fluid due to the deformation of valve seat or valve face during valve close operation can be prevented.

摘要： PURPOSE:To protect a handle from being brought into contact with other matter by inserting the handle removably in the axial direction into the input section of a drive screw member while providing a restricting means of an anti-removal chip for the handle together with an intermediate transmission tool. CONSTITUTION:A handle 7 of a stop valve 5 is fastened through rotation so as to screw a drive screw member 25 against a valve box 9. The handle 7 is inserted rollably and removably in the axial direction into an input section 25a of the drive screw member 25 while a spring S and an intermediate transmission tool 26 are arranged in a valve close thrust transmission system T. A restricting means 35 of an anti-removal chip 29 for the handle 7 is provided across the drive screw member 25 and the intermediate transmission tool 26. Since the handle can be removed under closed condition of the stop valve, it is protected from being brought into contact with other matter.

摘要： PURPOSE:To prevent opening-closing miss by providing a piston for opening and closing capable of moving with a gas filling mouthpiece in parallel devising it possible to successively carry out the motion to insert the piston into a cylinder casing and the motion to make the gas filling mouthpiece contact with a valve casing and enabling the piston for opening and closing to float in the radial direction. CONSTITUTION:When a gas filling mouthpiece 56 is inserted into a peripheral inner wall 6b of a nozzle 6 at the time of filling gas, the top end of an opening-closing piston 49 enters a cylinder casing 48. Simultaneously, a brim 56a of the gas filling mouthpiece 56 makes contact with a top end surface 6a of a gas outlet nozzle 6, and the gas filling mouthpiece 56 is fixed on the aforementioned peripheral inner wall 6b with a box nut 57. When gas is press-led inside a check valve 15 in this state, differential force of differential area of pressurized areas Au and Ac for valve opening and closing works to the left side, and a check valve body 42 becomes open. Consequently, it is possible to carryout the motion to insert the opening-closing piston and the motion to fix the gas filling mouthpiece 56 successively. Additionally, the opening- closing piston 49 automatically moves in alignment against a piston support tool 58 by a space between the brim part 56a and the box nut 57 and it is possible to prevent opening valve miss.

摘要： PROBLEM TO BE SOLVED: To keep secondary pressure of a coned disc spring type pressure reducing valve to a set range. SOLUTION: A pressure reducing valve 8 is arranged in series with a shut-off valve 7 between an entrance hole 4 and an exit hole within a housing 3. A gas filling passage 10 is arranged in parallel to the pressure reducing valve 8. A first check valve 11 and a secondary side safety valve which communicates with the exit hole are provided on the gas filling route 10 to prevent flow from this entrance hole 4 to the exit hole. This pressure reducing valve 8 opens, closes and moves a piston member 59 by balancing of spring force for opening valve and secondary side pressure for closing valve. This piston member 59 is pressed to an opening side by a first belleville spring F and the first belleville spring F is connected with a second belleville spring S in series. The second belleville spring S is compressed by a pressing tool 66 projected from a cover member 61.

摘要： PURPOSE: To provide a valve device in which a gas filling work can be efficiently performed, and the device can be made compact. CONSTITUTION: A gas inlet port 4, an inlet passage 8, a closing valve chamber 25 for a closing valve 7, an outlet passage 9, and a gas outlet port 5 are successively allowed to communicate each other within a valve box 3. The gas outlet port 5 is allowed to communicate with the inlet passage 8 by a gas filling passage 10. The gas filling passage 10 has a check valve 11 for arresting the flow from the inlet passage 8 to the closing valve chamber 25. When a high pressure gas is filled in an empty gas cylinder 1, the high pressure filling gas is supplied from a gas filling metal fitting connected to an outlet nozzle 22 as a closing member 26 in the closing valve chamber 25 is still closed. Then, the filling gas is carried from the gas outlet port 5 into the closing valve chamber 25 to open a check member 36 by the pressure, successively passed through the inlet passage 8 and the gas inlet port 4, and filled in the internal space A of the gas cylinder 1.

摘要： PURPOSE:To eliminate plastic deformation of a disc spring and to prevent leakage in the valve closing condition by providing a contact transmission portion between a propeller screw member and an intermediate transmission means, and setting the transmission contact position in the midway position of the compressive operation area of the disc spring. CONSTITUTION:Disc springs S are stacked in a spring chamber 32 formed between a rotation absorbing transmission means 41 and the intermediate transmission means 26. Contact transmission means 40 is disposed in such a manner as to be parallel transmission to the disc spring S between the intermediate transmission means 26 and rotation absorbing transmission means 41. The contact transmission portion 40 comprises a stepped portion 27 of the intermediate transmission means 26 and a spring bearing surface 41a of the rotation absorbing transmission means 41, and the transmission portion 40 is set in the midway position of the compressive operation area of the disc spring S. Accordingly, when the valve is operated to close, the disc spring S is stopped being further compressed in the midway of the compressive operation area to prevent totally compression condition, so that even if the accumulated frequency of valve closing operation becomes larger, the elastic condition can be kept.
