  • Patent number: 9080690
    Abstract: Tunable check valves reduce valve-generated vibration to increase the reliability of tunable fluid ends. Selected improved designs described herein reflect disparate applications of identical technical principles (relating to, e.g., the vibration spectrum of an impulse). Tunable check valve embodiments comprise a family including, but not limited to, tunable check valve assemblies, tunable valve seats, and tunable radial arrays. Each such tunable embodiment, in turn, contributes to blocking excitation of fluid end resonances, thus reducing the likelihood of fluid end failures associated with fatigue cracking and/or corrosion fatigue. By down-shifting the frequency domain of each valve-closing impulse shock, initial excitation of fluid end resonances is minimized.

  • Publication number: 20140290604
    Abstract: For controlling motion of a movable part, a device comprises a first chamber and a second chamber in fluid communication with each other via a variable orifice that is responsive to pressure within the first chamber. Movement of the movable part is thereby at least partially controlled by flow of a fluid from the first chamber to the second chamber via the variable orifice. An increase in pressure in the first chamber may cause an increase in orifice area, whereas a decrease in pressure may cause a decrease in the orifice area. Pressure-dependent elements that change geometries and/or the pressure-based opening/closing of one or more bypass channels may be used for this purpose. Where bypass channels are used, a valve may be opened/closed based on an operating parameter of a system in which the movable part is a component. Such a system may comprise an internal combustion engine.

  • Publication number: 20140217314
    Abstract: A self-closing water-saving valve assembly has a casing, a seat, a pushing rod, a closing member and a stand. When said valve assembly is switched off, the closing member and the stand slow down the closing movement into a gradual manner, which can effectively reduce positive and negative pressure waves generated in the water pipe. Noises and damage to the water pipe are also prevented. Besides, the pushing rod is moved down by gravity and slight water pushing, which eliminates the problems of wear and speeded-up movement of the pushing rod. Therefore, the valve assembly has prolonged lifespan. In addition, the water pressure is not directly applied on the pushing rod and only slight water pushes the pushing rod such that it is easier for a user to push the pushing rod to switch on the valve assembly.

  • Patent number: 8567753
    Abstract: A tunable valve assembly comprises a valve body, an adjustable preload flange centrally coupled to the valve body, and a viscoelastic element; the assembly attenuates valve-generated vibration transmitted to a pump housing. The vibration spectrum is narrowed and its amplitude reduced through hysteresis loss of closing impulse energy. The viscoelastic element comprises a peripheral groove portion coupled to a central reservoir portion via a plurality of fenestration portions. At least a first predetermined assembly resonant frequency is achieved by changing valve assembly compliance (with associated hysteresis loss) through adjustment of annular shear preload applied by the flange to the viscoelastic element reservoir portion. Such preload adjustment effectively maximizes hysteresis loss at the resonant frequency. At least a second predetermined assembly resonant frequency is achieved through choice of a circumferential shear-thickening material within the viscoelastic element groove portion.

  • Patent number: 8567754
    Abstract: Tunable valve assemblies attenuate valve-generated vibration at one or more predetermined assembly resonant frequencies which are typically altered to correspond to specific pump housing resonant frequencies. Each tunable valve assembly comprises a valve body having a peripheral groove spaced radially apart from a central reservoir. An adjustable flange may be coupled to the valve body for imposing a predetermined shear preload by partially constraining a viscoelastic element in the reservoir. One or more valve assembly resonant frequencies are thus predictably altered. Further, the associated valve-generated vibration spectrum is narrowed, and its amplitude is reduced through hysteresis loss of closing impulse energy at each predetermined assembly resonant frequency. Assembly resonant frequencies are additionally or alternatively altered through choice of viscoelastic elements and inclusions (e.g., shear-thickening materials) in the reservoir and/or peripheral groove.

  • Patent number: 8467907
    Abstract: A self-contained valve actuator of the present invention can comprise an actuator component. This actuator can be linear or quarter turn depending on the valve. The actuator can be double acting which means the piston will move once to open and once to close. The self-contained valve system uses hydraulic fluid to operate the valve. The valve system is directly powered with electric power from a battery. Solar panels are also incorporated to capture solar energy and convert this energy into electrical energy. This converted electrical energy is stored in the battery which enables the battery to continuously supply energy while substantially reducing the possibility of exhausting battery power. This resupply of electrical energy and the use of the hydraulic fluid creates a self-contained valve actuation system.

  • Publication number: 20130119285
    Abstract: The shut-off valve testing system provides for the testing of the main shut-off valve of a combustible gas supply line in such facilities as refineries, factories, or other plants utilizing such gaseous fuel. The system includes a double-ended hydraulic cylinder receiving hydraulic pressure from a suitable source, the cylinder communicating hydraulically with a hydraulic actuator for the main shut-off valve. The system provides for testing of the shut-off valve by actuating the valve through a portion of its full travel, thus confirming that the valve is free. This is accomplished by shutting off the pressure to one side of the double-ended hydraulic cylinder, and opening the hydraulic line between the cylinder and the actuator. Thus, hydraulic pressure from the actuator can bleed to the cylinder, allowing the actuator to move to the extent of the limiting spring and/or hydraulic pressure to the opposite side of the cylinder.
