摘要： An enclosure containing an inerting gas and at least one liquid to be discharged. This enclosure comprises at least one orifice positioned in its lower part and a liquid discharging system positioned at the orifice. This liquid discharging system is configured to take up a closed state and an open state in which the system allows the liquid to flow towards the outside of the enclosure and includes at least one element that is elastically deformable depending on the pressure inside the enclosure and, depending on its deformation, controls the open or closed state of the liquid discharging system. This solution makes it possible to achieve simple and automatic regulation of the volume of the liquid in the enclosure, without a sensor. An aircraft including at least one such enclosure is also provided.

摘要： A pressure relief mechanism includes: a pedestal, a cover assembly, and a position limiter. An exhaust port is provided on the pedestal. The cover assembly is configured to close or open the exhaust port. The position limiter is snap-fastened to the cover assembly. The position limiter includes a first elastomer and a first limiting portion. The first limiting portion is configured to: when the cover assembly closes the exhaust port, restrict the position limiter from moving relative to the pedestal; and when a pressure in the box increases, make the position limiter move along an opening direction of the cover assembly to free the first limiting portion from constraint of the pedestal and enable the position limiter to rotate relative to the cover assembly under resilience of the first elastomer.

摘要： A safety valve includes an inlet, an outlet, two shut-off valves arranged behind one another, and a discharge valve with a discharge outlet. The two shut-off valves and the discharge valve are connected by an inlet and outlet respectively. The safety valve has a housing main body, relative to which a piston is guided movably, and which has a housing cover guided movably on a side lying opposite the housing main body. The inlet is arranged on the piston, the outlet is arranged on the housing cover, each of which merges into a bore closeable by one sealing surface arranged on the piston and the housing cover respectively. The housing cover and the housing main body form a cavity, in which the bores end. A circumferential gap formed when the housing cover is lifted off produces the discharge outlet.

摘要： A hydrogen supply combination valve having flow regulation and pressure stabilization functions includes a first-stage pressure reduction valve, a second-stage pressure reduction and flow regulation valve, and a second-stage pressure reduction and regulation valve. The first-stage pressure reduction valve realizes main throttling and pressure reduction effects, and performs first-stage pressure reduction on high-pressure hydrogen. The second-stage pressure reduction and flow regulation valve can further perform second-stage pressure reduction on the hydrogen after first-stage pressure reduction, and can realize flow regulation. The second-stage pressure reduction and regulation valve can further perform second-stage pressure reduction on the hydrogen after first-stage pressure reduction.

摘要： Methods and kits for assembling a flow cage assembly are provided. The flow cage assembly may be used in a traveling valve, a standing valve, or a top plunger adapter of a downhole reciprocating pump. In some embodiments, the method comprises assembling a body, a tubular insert, and a retaining element such that the retaining element forms an interference fit with the body and thereby securely retains the tubular insert within the body. Top plunger adapters are also provided, assembled from embodiments of the methods and kits.

摘要： A pressure-reducing valve 1 includes a tubular valve body 3 movably accommodated in a housing 2, a valve seat 4 fixed inside the housing 2, and an urging member 5 that urges the valve body 3 in a direction separating from the valve seat 4. The valve seat 4 includes an annular elastic member (O-ring 42) capable of abutting against the valve body 3, an annular portion (inner ring portion 41b) that covers an outer periphery of the elastic member, an inner peripheral portion 43b disposed on an inner periphery of the elastic member, a connecting portion (closing plate portion 43a) that connects the annular portion and the inner peripheral portion 43b, and a detachment prevention portion provided in at least one of the inner peripheral portion 43b and the annular portion on a valve body side to prevent the elastic member from detaching from the annular portion.

摘要： A relief valve includes: a housing having a hollow cylindrical valve chamber and having a first communication port opening on one end side of the valve chamber; a first valve element for opening and closing the first communication port; a first spring for biasing the first valve element in the closing direction; and a retainer having a spring seat for supporting the first spring. A set load of the first spring is adjusted based on the press-fit amount of the retainer with respect to the housing. A press-fit piece member including a plurality of press-fit pieces is formed in the retainer, such that the press-fit pieces of the press-fit member are arranged to be spaced away from each other in the circumferential direction of the retainer and elastically abut the housing.

摘要： A spring-operated relief valve can include a main spring positioned between a bottom spring seat and a top spring seat. A seat assembly can include a valve seat, a seat retainer, and a spindle. The valve seat and the spindle can be received within an inner bore of the seat retainer and the spindle and the seat retainer can be threadably coupled. The valve seat can extend partially through the seat retainer to form a seal with a nozzle of the spring-operated relief valve and the spindle can engage the bottom spring seat to compress the main spring during a valve relief event.
