    摘要： A variable pressure regulator control device comprising a valve body having a fluid inlet, a fluid outlet, a fluid pressure-sensing chamber, and a valve seat in fluid communication with said inlet and defining an opening into said chamber, a resilient member having an outer edge and a self-restoring wall of the chamber which is responsive to pressure in said chamber, a valve stem extending through said chamber towards the valve seat, a valve element cooperating with said valve seat, said valve element being located between the valve seat and said fluid inlet, an adjuster mounted to said valve body in a position to deflect said resilient member, thereby moving the valve element away from the valve seat while said member flexes in response to pressure changes within said chamber to control the position of the valve element with respect to the valve seat, wherein said valve body includes a base incorporating said inlet, said outlet, and said valve seat, a retainer mounted atop said base, said retainer having an aperture for receiving said adjuster, and a cover fixing said adjuster for rotation therewith such that deflection of said resilient member is capable of being adjusted by rotation of said cover.

    摘要： A check valve is for use in a fluid system. A valve body has an inlet end, a valve cavity, and an outlet end. A valve enables a valve assembly to control the flow of fluid therethrough. A plug of the valve assembly includes tapered and non-tapered sections, the tapered section having a cross section that increases in diameter in a direction that is downstream from the inlet end of the valve body. A sealing ring is mounted to reciprocate on the non-tapered section and an elastomeric actuation ring is mounted along the tapered section. The tapered section biases the actuation ring to a normal position, at which the actuation ring contacts and positions the sealing ring in contact with the valve body and the valve assembly to prevent fluid from flowing out the outlet end of the valve body.

    摘要： A device comprising a plug positioned within a housing to regulate air within a container, for example, plastic storage containers or bags. The plug is positioned within the housing to occlude a port hole in the housing. The housing is positioned within a container so the port hole faces a wall of the container. A hole is created in the container above the port hole. To evacuate or inject air into the container, a hose adaptor with a specialized hose tip is connected to a vacuum or air hose. When inserted into the port hole, the hose tip temporarily displaces the plug from the port hole. Vents within the housing allow air to move through the housing and into or out of the hose tip. Removal of the hose tip allows the plug to resume position over the porthole to maintain the vacuum or air pressure within the container.

    摘要翻译： 一种装置，其包括定位在壳体内的插塞，以调节容器内的空气，例如塑料储存容器或袋子。 插头位于壳体内以封闭壳体中的端口孔。 壳体定位在容器内，使得孔口面向容器的壁。 在孔口上方的容器中形成一个孔。 要将空气排空或注入容器，带有专用软管头的软管接头连接到真空或空气软管。 当插入端口孔时，软管尖端将端头孔暂时移位。 外壳内的通风口允许空气移动通过外壳并进入或离开软管尖端。 去除软管尖端允许塞子恢复位于孔口上方的位置，以保持容器内的真空或空气压力。
