摘要： A sealing device is provided for use with a fitting. The fitting has circular port and a flow path with a longitudinal axis. A circular port encircles a portion of the flow path opposite the port with the sealing device inserted into the port. The sealing device has a circular top with two opposing surfaces depending therefrom but inclined so the surfaces are closer at the top. A continuous sidewall joins the periphery of the two surfaces. The opposing surfaces are inclined and spaced apart further at the top than at an end opposite the top. A cylindrical hole through the opposing surfaces encircles the flow path during use.

摘要： A pipeline pressure testing assembly has a fitting defining a flow path and having a port on a wall of the fitting into which a pressure testing device is removably inserted along a central axis of the port for pressure testing. The port is circular, larger than the interior diameter of the pipeline and located at or above the tube forming the flow path through the fitting. The fitting has a recess encircling at least part of the flow path and opening to the port to receive the testing and sealing devices. The recess is formed by two opposing walls inclined relative to the central axis of the recess. The recess walls at the top of the flow path by the port are spaced apart a distance as large as the pipe diameter for cleanout and inspection. A tubular valve stem screws into the testing device and has a rotary valve blocking flow through the tubular valve stem. Flow through the fitting is blocked with the rotary valve closed and the tubular valve stem in a first position. Flow through the testing device is allowed with the rotary valve closed and the tubular valve stem in an open position. With the rotary valve open, flow through the tubular valve stem is permitted when the tubular valve stem is in either the first or second position to provide multiple drain and fill options.

摘要： A method and device for pressure testing a pipe line is provided wherein a fitting is inserted into the pipeline by inserting male ends of the pipeline into female ends of the fitting to define a flow path through the fitting extending along a longitudinal axis. The fitting has an internal recess cooperating with a test slide to block flow through the fitting. An externally accessible port allows insertion and removal of the test slide. The test slide has an internal recess in which a pressure release slide moves to open a hole to release pressure, and to close the hole to block flow through the fitting for pressure testing. After testing and the release of the fluid test pressure, the test slide is removed and a finish slide is inserted into the recess. The finish slide has an opening located and configured to coincide with the flow path through the male ends of the pipes, and to block the recess to provide a substantially uniform, cylindrical flow path through the fitting.

摘要： A clamp assembly releasably secures a plumbing pipe to a support. The assembly has a clamp base releasably connected to a clamping block by pawls that releasably engage a pair of ratchet arms extending from the base. Each of the base and clamping block has two inclined surfaces forming a generally V-shaped notch that opens toward the pipe. A cap is optionally placed over one or both of the V-shaped notches and is interposed between the notch and the pipe. At least one resilient leg or a flange may extend from the base opposite the ratchet arms, with the flange and/or the arms resiliently engaging opposite sides of the support to hold the clamp assembly in position.

摘要： A method and device for pressure testing a pipe line is provided wherein a fitting is inserted into the pipeline by inserting male ends of the pipeline into female ends of the fitting to define a flow path through the fitting extending along a longitudinal axis. The fitting has an internal boss extending around a circumference of the flow path and extending radially inward toward the centerline a distance corresponding to the wall thickness of the mating male ends of the pipes so the pipes and boss define a periphery of the flow path through the fitting. A recess is formed in the boss to sequentially receive two slides. An externally accessible port allows a test slide to be inserted into the recess, with the test slide sealing against the walls defining the recess to form a fluid-tight seal for pressure testing the line. The test slide is removed and a finish slide is inserted into the recess. The finish slide has an opening located and configured to coincide with the flow path through the male ends of the pipes, and to block the recess to provide a substantially uniform, cylindrical flow path through the fitting.

摘要： The invention disclosed herein comprises a self-contained breathing apparatus regulator having a valve seat for overlying the crown of an orifice wherein high pressure gas is regulated by said valve seat into said orifice. The valve seat has a valve seat body of an inverted T shaped configuration. The upright portion of the T shaped configuration is seated within a spring block assembly having a seal around said upright portion. A continuous plastic coating is provided around the valve seat body into the zone of said orifice and beyond the zone of said seal so as to expose the junction only to intermediate pressure to prevent delamination of the plastic from the valve seat body.

摘要： An adjustable regulator of the type having fluid coupling oil within a cavity exposed to ambient pressure and overlying a diaphragm which operates based upon imbalances of said ambient pressure and an intermediate pressure zone on the other side of said diaphragm. The adjustment of the spring on the diaphragm is accomplished by means of a cap screw which is screwed into the sidewalls of the regulator within the cavity holding the oil. The oil is prevented from draining from the cavity by a second diaphragm overlying the oil in the cavity which can flex based upon changes in ambient pressure. The cap screw has a threaded extension in the form of a stem and tool surface on the other side of said stem for turning said cap screw. The stem passes through the second diaphragm in a sealed manner to prevent flow of coupling fluid between the interface of the diaphragm and the stem while at the same time allowing for adjustment by turning the cap screw in its adjacent threads so that compression can be changed with regard to the spring thereby adjusting the entire regulator. A further improvement is a valve seat which deters delamination of the valving surface between the metal of the valve seat and the sealing material by the sealing medium extending into an intermediate pressure zone to help prevent delamination from the metal surface.

摘要： A first stage scuba regulator operates to supply breathable air at a pressure of say, about 125 psi above ambient to a second stage demand regulator. The first stage regulator includes a piston subjected on one side to ambient pressure, and on the other to downstream air pressure, and so arranged as to open when the ambient pressure overpowers downstream pressure by a preset amount determined by a bias spring and to close when downstream pressure rises to the present amount. Instead of directly conducting outside water to the first side of the piston, an inert barrier fluid of high molecular weight is used that fills the piston chamber. Low temperature silicone grease is the preferred material. The barrier fluid is retained by a porous closure that offers very limited restriction to the flow of water, but significantly greater resistance to the flow of the barrier fluid. The mechanism is protected from malfunction due to icing and is isolated from sand, silt, coral and other particulate matter having deleterious effects upon rubber seals and other parts of the mechanism.
摘要翻译：第一级水肺调节器用于向例如约环境温度约125psi的压力向第二级需求调节器提供透气空气。第一级调节器包括在一侧受到环境压力的活塞，另一方面承受下游空气压力，并且当环境压力超过下游压力超过由偏置弹簧确定的预设量并打开时打开下游压力上升到目前的水平。代替直接将外部水引导到活塞的第一侧，使用填充活塞室的高分子量惰性阻挡流体。低温硅脂是首选材料。阻隔流体由多孔封闭体保持，其对流动的流动提供非常有限的限制，但对阻挡流体的流动具有显着更大的阻力。该机构由于结冰而受到防止故障的影响，并且与橡胶密封件和机构的其它部件有不利影响的沙子，泥沙，珊瑚和其他颗粒物质隔离。
