摘要： A fitting for collecting or distributing high-pressure fluid via fluid transmission lines is provided. The fitting includes a body, and a plurality of apertures formed in the body in a common plane, intersecting inside the body such that all of the apertures are in mutual fluid communication. Each of the apertures is configured to receive a threaded coupling member of a respective high-pressure transmission line. The fitting also includes first and second compression members positioned on opposing sides of the body and coupled thereto so as to exert a compressing bias to the body in an axis perpendicular to the common plane. The compression members each comprise a raised contact surface corresponding to the region of the body where the plurality of apertures meet, and through which the compressing bias is exerted. The fitting may be an elbow-fitting, a tee fitting, a cross-fitting, or some other configuration.

摘要： An apparatus and method for pressure processing a pumpable substance, such as a pumpable food product or slurry. In one embodiment, the apparatus includes a pressure vessel having an inlet valve toward one end and outlet valve toward the other end. A flexible bladder is coupled between the inlet and outlet valves for receiving the pumpable substance. The pressure vessel can further include a high-pressure inlet port for receiving high-pressure fluid that biases the membrane inwardly to pressure process the pumpable substance. The pumpable substance is then removed from the vessel through the outlet valve.

摘要： An assembly for changing the temperature of ultrahigh-pressure fluid as it flows through ultrahigh-pressure tubing includes several thermally conductive blocks. Each block has a first bore through which the ultrahigh-pressure tubing passes, and a second bore containing a source of heating or cooling. Alternatively, resistance heating is used to increase the temperature of the ultrahigh-pressure fluid, by coupling electrodes to the outer surface of the tubing. The ultrahigh-pressure fluid is heated or cooled after it is pressurized, and is then discharged from the ultrahigh-pressure tubing at a selected temperature for use. For example, the ultrahigh-pressure fluid at a selected temperature may be discharged through a nozzle to form an ultrahigh-pressure fluid jet to cut or clean any desired surface or object, or it may be discharged to a pressure vessel to pressure treat a substance.

摘要： A high pressure relief valve for use in a high pressure fluid pump is shown and described. In a preferred embodiment, a valve seat is provided with a tapered hole and with a conduit, the tapered hole and conduit being in fluid communication with each other and with fluid having a variable pressure. A tapered pin having grooves is held in the tapered hole by a control force, or control pressure acting through a plunger. When the pressure of the fluid is sufficiently high to overcome the control force or pressure, the tapered pin is forced to move sufficiently to create an annular clearance between the tapered pin and the tapered hole, thereby allowing pressurized fluid to flow past the pin to an outlet. An outer surface of the valve seat in a region of the tapered pin is tapered in an opposite direction to that of the tapered hole, thereby weakening the valve seat in that region, such that the tapered hole is able to expand and contract as the pressure of the fluid increases and decreases.

摘要： A high pressure fluid seal assembly is shown and described. The seal assembly includes a seal carrier having a bore through which a reciprocating pump plunger may pass, the seal carrier having a first annular groove concentric with the bore, and carrying an annular seal. The seal carrier further includes an integral annular guidance bearing positioned in a second annular groove of the seal carrier, the second annular groove and guidance bearing contained therein being axially spaced from the first annular groove and seal contained therein. An inner diameter of the guidance bearing is smaller than an inner diameter of the seal carrier in a region between the seal and the guidance bearing. The seal is therefore supported directly by the seal carrier, although the seal carrier is spaced from the reciprocating plunger by the guidance bearing. Frictional heating in the region of the seal is therefore reduced, thereby increasing the life of the seal. Materials for the plunger, seal and guidance bearing are selected to minimize friction between the plunger and seal and between the plunger and guidance bearing. Furthermore, the seal assembly is manufactured by pressing the guidance bearing into the seal carrier, and then machining the bore in the guidance bearing and in the seal carrier in the same setup, thereby improving the alignment of the elements and simplifying manufacturing.
摘要翻译：示出并描述了高压流体密封组件。密封组件包括具有孔的密封载体，往复式泵柱塞可穿过孔，密封载体具有与孔同心的第一环形槽，并且承载环形密封件。密封托架还包括定位在密封载体的第二环形槽中的整体环形引导轴承，其中容纳的第二环形槽和引导轴承与其中容纳的第一环形槽和密封件轴向间隔开。引导轴承的内径小于密封件和引导轴承之间的区域中的密封件的内径。因此，密封件由密封载体直接支撑，尽管密封载体通过引导轴承与往复式柱塞间隔开。因此，密封区域中的摩擦加热减少，从而延长密封件的使用寿命。选择柱塞，密封和引导轴承的材料，以最小化柱塞和密封件之间以及柱塞和导向轴承之间的摩擦。此外，通过将引导轴承压入密封载体，然后在同一设置中在引导轴承和密封载体中加工孔，从而改善元件的对准并简化制造，来制造密封组件。

摘要： A low wear poppet valve in a high pressure reciprocating pump. Relative movement of the mating surfaces due to compressive distortion is eliminated. There is a valve seat having a flow passage and an upper mating surface, and a poppet element which sealingly abuts this. The flow passage is in communication with a low pressure zone, and the outer surfaces of the seat and element are in communication with a high pressure zone. The poppet element has a recess in its mating surface surrounded by a wall portion, and the low pressure zone is communicated from the flow passage into the interior of the recess. This enables the wall portion of the element to be displaced inwardly and outwardly in concert with the wall portion of the seat by the cyclic pressure differential which is generated between the zones by the operation of the pump. This eliminates relative movement between these parts which would otherwise cause fretting wear of their mating surfaces.
