摘要： The present invention is to provide a thermally-sensitive safety device for gas tubing including a main body provided with an inlet, an outlet and a gas passage communicated with said inlet and said outlet, and a thermally-sensitive control valve mounted in the gas passage. The control valve has a ball, which is normally biased by a spring to stop against a thermally-sensitive member, and a bushing with through hole in alignment with the ball. The thermally-sensitive member melts while ambient temperature is higher than the melting point thereof, whereby said ball is biased by said spring to contact against and seal the through hole of the bushing such that the gas passage is blocked off.

摘要： A firestop coupling assembly (10 or 210) for allowing the passage of utility members (50 or 52) through a penetration in a partition (54 or 56) while preventing the transmission of fire and smoke through the penetration. The coupling assembly includes an outer sleeve (12 or 212) and an inner conduit (16 or 216). The outer sleeve has a concentric indention (12D or 212D) around its inner surface within which is mounted an intumescent material (20 or 220). In one (1) embodiment, the inner conduit is mounted in the open top end of the outer sleeve so that the second end (16B or 216B) of the inner conduit is adjacent the intumescent material. In another embodiment, the inner conduit is adjustable along the length of the outer sleeve. A plug (22 or 222) can be provided in at least one end of the inner conduit allowing passage of at least one (1) utility member through the assembly. In another embodiment, the inner diameter of the inner conduit is only slightly greater than the outer diameter of the utility member so that the utility member can be solvent welded to the inner surface of the inner conduit. When the coupling assembly is exposed to heat, the intumescent material expands into the inner passageway of the outer sleeve and prevents the transmission of smoke and fire through the coupling assembly.

摘要： Inside the casing (1), there are three or more ribs (8) arranged with their longitudinal axes parallel to the closing body's direction of movement when closing so that each rib forms a slide-way for the closing body (5) moving from open into closed position. Into each of these ribs there is cut a first groove (10) in which is placed a shaped part (11) that supports the closing spring (9). At least the ribs arranged approximately opposite to the tappet (20) have a second groove whose side facing the seat (7) forms a rest edge (18) on which the control edge may rest when the closing body is in open position. When the fusible soft solder component (21) is melting away, the tappet changes its position in axial direction under the force exercised by the closing spring. Due to this change of position, the control edge is no longer resting on the rest edge, and the closing body driven by the dosing spring switches over into its close position.

摘要： A well control system having well controlled fluids distributed through pipes includes valves that are opened by a heat softened valve obstruction element. The translation of a fluid flow obstructing gate in a gate valve is driven by a stem element attached to the gate. Without a mechanical or fluid obstacle, fluid pressure in the distribution pipe above about 2 psi will drive the valve gate to a biased position. This internal pressure displacement of the valve gate also displaces the gate stem. In the present invention, the displacement of gate stems for critical valves from a normal maintenance position to an emergency activation position, is obstructed by a fusible barrier that is secured across the gate stem translation path. In the event of a well fire, at a predetermined temperature of fusion, the barrier element will no longer resist the displacement force imposed by the stem. The internal pipe pressure on the stem will force penetration of the stem through the fusible barrier thereby permitting the valve to open and release fluids into the well for the purpose of plugging uncontrolled well flow and extinguishing the fire.

摘要翻译： 通过管道分布的具有良好控制的流体的井控系统包括由热软化阀阻塞元件打开的阀。 闸阀中的流体阻流门的平移由连接到闸门的杆件驱动。 没有机械或流体障碍物，分配管中的流体压力大于2psi将驱动阀门到偏置位置。 阀门的这种内部压力位移也使闸门杆移位。 在本发明中，用于临界阀的门杆从正常维护位置到紧急启动位置的位移被固定在闸杆平移路径上的可熔屏障所阻挡。 在井火的情况下，在预定的熔融温度下，阻挡元件将不再抵抗由杆施加的位移力。 杆上的内部管道压力将迫使阀杆穿过可熔屏障，从而允许阀门将流体打开并释放到井中，以堵塞不受控制的井口流动并扑灭火灾。

摘要： The valve is intended to be opened at a predetermined temperature in order to release the pressurized fluid from the tank and its opening is triggered by melting of a meltable material. It comprises a body in the shape of a socket (10), the open end of which is exposed to the gas pressure and the bottom of which is closed except for a minuscule orifice (12). The side wall of the body (10) comprises at least one radial opening (14) and the body (10) is engaged, by its bottom, by sliding, in a cap (16) of complementary shape and is fastened thereto by means of the meltable material (18). The cap (16) comprises at least one access (20) to the atmosphere and, after melting of the meltable material (18), can be moved with respect to the body (10) until each access (20) communicates with a side opening (14) in the body (10).

摘要： A fire prevention safety device for a gas meter (3) has closure means (4, 4′, V) that can be activated by heat to interrupt the gas supply into the gas meter (3) in the event of a fire. The gas meter (3) is arranged in a bypass (2) of a gas pipe (1). At least one of the aforementioned closure means (4, 4′, V) for interrupting the gas supply is in each case arranged in the bypass (2) in the flow direction upstream and downstream of a sensor (31) belonging to the gas meter (3). The device permits a cost-efficient, simple and effective fire prevention safeguard, in particular for electronic gas meters.

摘要： A heat-responsive fuse cord is positioned in the proximity of a pressure vessel and is thermally coupled to a thermal-pressure relief device which is in communication with the pressurized contents of the vessel. When ignited the fuse cord burns to a thermal coupler, transferring the heat to the thermal actuator of the TPRD. In a kit form, fuse cord and a thermal coupler provide an economical remote and retrofit triggering system for TPRD's having an otherwise limited environment of influence.
