摘要:
A valve device includes a body (4) in which a gas flow passage is provided; and a check valve (16) provided in the gas flow passage, the check valve (16) including a poppet (84) and a valve seat. The poppet (84) excluding a block portion (91) is in a form of a hollow shaft, the block portion (91) being located at a distal end of the poppet (84) and having a taper shape, and the poppet (84) has at least one side hole (95) that provides communication between an inside and an outside of a portion of the poppet (84), the portion being in the form of the hollow shaft. The at least one side hole (95) extends obliquely with respect to a central axis line of the poppet (84) such that the at least one side hole (95) extends along a gas flow direction inclined with respect to a direction in which the poppet (84) moves when the check valve (16) opens.

A valve device for a gas tank, includes a body (4) and a check valve (16) provided in an injection passage (13) to inject gas into the gas tank. The check valve (16) includes a valve seat (33), a case (34) fixed in the injection passage (13) while a space is provided between an inner peripheral surface (31a) of the injection passage (13) and the case (34) to enable gas to flow through the space, and a valve element (35) accommodated in the case (34). The case (34) includes a cylindrical portion (41), and is configured such that the bottom (42) of the cylindrical portion (41), provided at an opposite side to the valve seat (33), defines a range where the valve element (35) is axially movable. The valve element (35) includes a head portion (51) that can block a valve hole (37) of the valve seat (33), and a sliding portion (53) formed to be axially movable with respect to the cylindrical portion (41).

A valve device includes a body (11), a solenoid valve (12) accommodated in an accommodation hole (23) of the body (11), and a joint member (110) fixed to the body (11). The solenoid valve (12) includes: a sleeve (41) having a tubular shape and fitted in the accommodation hole (23), and including an introduction passage (66) and a delivery passage (68); and a valve element (71) configured to open and close the passages (66, 68). A U-seal (57) is disposed between an outer wall surface of the sleeve (41) and an inner wall surface of the accommodation hole (23). The body (11) has an attachment hole (80) that is located downstream of the delivery passage (68) of the sleeve (41) and opens on an outer surface of the body (11). The joint member (110) including a backflow reduction valve (122) is fixed to the attachment hole (80).
摘要:
A safety valve mounted on a container and configured to release gas in a container in the case where the temperature rises, in which the safety is secured and a cost reduction is achieved. A movable body 12 includes a shaft portion 21 on which a compression coil spring 13 is fitted and a flange portion 22 configured to come into contact with a fusible alloy 11 by being urged by the compression coil spring 13 . The flange portion 22 of the movable body 12 is provided with through holes 35 configured to discharge the fused fusible alloy 11 into a compression coil spring arrangement space 30.
