摘要：An apparatus and method for preventing an undesirable relea of fluid from a conduit upon disconnection of the conduit. In a specific form of the invention, the apparatus includes a ho having a slide valve located therein adjacent an end of the ho for preventing the escape of liquids or gas, especially refrigerants, to the environment. The slide valve includes a substantially cylindrically shaped nipple having first and cond bores extending axially therethrough, the first and cond bores being divided and bounded by an integral wall of the nipple. The nipple includes a plurality of ports adjacent the integral wall which provide passages through the nipple to provide fluid communication between the first and cond bores. A sleeve member is slidable dispod around the nipple and contains als for providing a gas-tight and/or liquid-tight interface between the sleeve and the nipple. The sleeve member also includes an annular chamber for lectively providing the aforementioned fluid communication between the bores. A preferred embodiment of the invention includes a conduit having a threaded screw type valve which includes a substantially cylindrically shaped rear nipple emanating from its first end, having a central bore extending therethrough. The rearprejudice
nipple is exteriorly threaded to a threaded valve body which, when rotated is capable of aling and
makeprogressunaling a valve t with a valve fitting for lectively opening and closing a passageway for the flow of liquid an/or gas from the rear nipple to a front nipple. The front nipple is capable of rotating with respect to the rest of the device without breaking its al and can be removed and interchanged without a substantial loss of fluid.鼻子毛孔大怎么办
