摘要： Improved methods and apparatus for pressure processing of pumpable substances are shown and described. In one embodiment, the apparatus includes an inlet valve, an outlet valve, and a pressure vessel. The inlet valve has an inlet port, and is coupled to a source of a pumpable substance and to the pressure vessel. The outlet valve has an outlet port and is coupled to the pressure vessel. When the inlet valve is opened and the outlet valve is closed, a volume of pumpable substance may flow into the pressure vessel. The inlet valve is then closed and the outlet valve remains closed, and the pumpable substance within the pressure vessel may be pressurized to a selected pressure for a selected period of time. The outlet valve is then opened, allowing the pumpable substance to be discharged. In an alternate embodiment, the apparatus may include at least one aseptic valve assembly having elements which cooperate to apply cleansing solution to one or more surfaces, the surfaces having the potential of being contaminated. The cleansing solution may be applied to the surface by cleansing chambers or by nozzles.

摘要： A collision detection sensor for a waterjet system provides a signal in the event the device approaches to within a selected distance of an obstruction in the plane of the working surface. An annular pressure switch lying in a first plane provides the signal when radial pressure is applied to a perimeter of the pressure switch via an annular trigger skirt, the trigger skirt applying the radial pressure in response to a collision of the device with an obstacle.

摘要： A contour follower includes a plurality of sensors spaced around a waterjet nozzle, each of the sensors being configured to measure a distance between a working surface and a first plane, perpendicular to a longitudinal axis of the nozzle. The sensors may include hall-effect sensors lying in the first plane and magnets lying in a second plane, parallel to the working surface. A detecting circuit processes signals from the sensors to determine an angle of the working surface, relative to the first plane, and a distance between an aperture of the nozzle and the working surface. A collision detection sensor provides a signal in the event the device approaches to within a selected distance of an obstruction in the plane of the working surface. A shield plate blocks and dampens secondary spray-back of cutting fluid occurring at low angles above the working surface.

摘要： An improved and tunable ultrahigh-pressure nozzle for use in generating ultrahigh-pressure fluid jets is shown and described. In a preferred embodiment, a nozzle body is provided with a first conical bore that extends from an entrance orifice to an exit orifice, the bore transitioning into a second conical bore that is formed in a seal. The seal is formed to capture a nozzle orifice and position it in the nozzle body adjacent the exit orifice. By selecting the geometry of the nozzle, namely the diameter of the entrance orifice, and an included angle of the first and second conical bores, it is possible to optimize performance of a fluid jet generated by the nozzle for a selected task and operating parameters.

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 hose assembly is manufactured wherein the nipple of the hose fitting includes an O-ring receiving groove formed about its periphery. The O-ring and groove are dimensioned so that the crimping of the fitting's outer sleeve causes the linear of the high pressure hose to flow into the groove, comprising the O-ring into the groove, and sealing against the O-ring within the groove.

摘要： An ultra-high pressure hose assembly capable of withstanding sustained internal fluid pressures exceeding 60,000 psi is disclosed herein and consists essentially of an innermost tubular core, a plurality of successive tubular layers and an outer containment sleeve. The innermost tubular core and containment sleeve are designed to add substantially no structural integrity to the overall assembly but rather function only as a fluid barrier and containment structure for the tubular layers respectively. The outer tubular layers serve as structural members of the overall assembly and respectively consist of individual bands which are alternately helically wound around and directly against the layers immediately below them at predetermined helix angles. Each band in turn consists of a number of separate steel wires which have opposing flat sides and which are positioned in unconnected edge to edge relationship to one another so as to form the band. In addition, the bands of successive layers, starting with the innermost tubular layer, define successively increasing helix angles, whereby to cause all of the layers to share substantially in the overall loading of the assembly at its operating pressure.
摘要翻译：本文公开了能够承受超过60,000psi的持续内部流体压力的超高压软管组件，其基本上由最内管状芯，多个连续管状层和外部容纳套管组成。最内层管状芯和容纳套筒被设计成基本上不对整个组件增加结构完整性，而仅仅作为用于管状层的流体屏障和容纳结构。外部管状层用作整个组件的结构构件，并且分别由单独的带组成，其以预定的螺旋角度交替地螺旋缠绕在其上并直接抵靠在它们正下方的层。每个带又由多个单独的钢丝组成，它们具有相对的平坦侧面，并且彼此位于未连接的边缘到边缘的关系，以便形成带。此外，从最内管状层开始的连续层的带限定了连续增加的螺旋角，从而使得所有层在其工作压力下基本上分布在组件的总体载荷中。

摘要： A pressure enclosure includes a first component having an opening, a second component coupled to the first component in a position over the opening, a third component positioned between the first and second components and covering the opening, and a load chamber defined by a space between the second and third components and configured such that pressure in the load chamber biases the third component against the first component to seal the opening. The pressure enclosure may be a cylinder of a pump for pressurizing fluid or gas, with the first component a cylinder body, the second component an end cap and the third component a valve body, with the load chamber biasing the valve body against the cylinder body.

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. 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.
