摘要： PROBLEM TO BE SOLVED: To provide a highly durable and long-life safety valve, which discharges an alloy with a low melting point speedily at the time of the safety operation and opens a gas release pathway quickly. SOLUTION: The gas release pathway 13 is sealed with the low melting point alloy 32 in the solid state via an actuator 33, and is opened when the low melting point alloy 32 melts. The low melting point alloy 32 is stored in an alloy storage chamber 30, where an alloy drain pathway 31 is formed for draining the melted low melting point alloy 32 out to the outside. The area of the opening of the alloy drain pathway 31 on the alloy storage chamber 30 side is narrower than that on the downstream side of the draining. COPYRIGHT: (C)2003,JPO

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 provide a gas cylinder valve which allows gas filling operation to be efficiently carried out, and also can be made compact. CONSTITUTION:A gas inlet port 6 opened at the lower face 5a of the leg section of a valve box 4, is communicated with a gas outlet port 8 through a gas inlet path 11, a stop valve seat 12 and a stop valve chamber 13 in order. The operation of a handle wheel 19 permits a stop valve body 16 inserted into the stop valve chamber 13 to open/close the stop valve seat 12. A gas receiving port 10 opened to the outer circumferential surface of the valve box 4 is communicated with the gas inlet path 11 by a gas receiving path 22. The gas receiving path 22 is provided with a check valve seat 27 and a check valve chamber 28 in order starting from the gas receiving port 10. A check valve body 30 inserted in the check valve chamber 28 is elastically pressed onto a check valve seat 27 by a check spring 31 so as to be closed.

摘要： PURPOSE:To reduce the cost of a valve system for a normally-closed type bomb valve as a whole by setting up one valve opening actuator to plural units of gas bomb's valves. CONSTITUTION:During conveyance or storage of a gas bomb 1, a valve opening actuator 40 is removed from an actuator supporting part 36 of a bomb valve 2, and a valve member 13 is pressed to a valve seat 12 for closing by dint of resilient force of a valve closing spring 29. When gas in this gas bomb 1 is taken out, first of all, a supported part 54 of the valve opening actuator 40 is attached to the actuator supporting part 36 of the bomb valve 2, then this actuator 40 is operated for opening, and the valve member 13 is separated from the valve seat 12 against the resilient force of the valve closing spring 29. If so, gas in the bomb 1 is taken out to a gas outlet 7 from a gas inlet 6 by way of a valve chest 9.

摘要： PURPOSE:To prevent a fluid from leaking with certaintity by installing a contact stopping part, checking any movement of a propulsive screw member to the valve closing side of more than the specified value, at the fixed side of a valve box, and setting a contact stopping position of this contact stopper part in a mid position of a compressive operating range of a belleville spring. CONSTITUTION:A handle 7 is rotated to the valve closing side from a valve closing state, and a valve face 14a is made contact with a valve seat 10a. In this state, a size of height between a rotation absorbing transmission device 31 and a contact stopper part 34 is D-E. In addition, contact force between the valve seat 10a and the valve face 14a is enhanced as a propulsive screw member 25 goes forward to the lower side by operation of the handle 7, and in the midway, the member 25 makes the transmission device 31 go down, whereas an intermediate transmission device 26 is stopped to the valve seat 10a via a valve body 14, so that a belleville spring S is compressed while closing contact force of the valve face 14a is gradually enhanced. A descent of the transmission device 31 is stopped by the stopper part 34 in the midway of compressive operation of the spring S, and the closing contact force of the valve face 14a is prevented from exceeding a proper value P.

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.
