PURPOSE: To miniaturize a failure detecting device and to lower the cost thereof. CONSTITUTION: There are provided a current detecting circuit 22 for detecting a current running through a coil 20 in a solenoid valve 18, and an warning lamp 26 for determining whether a valve element is normally operated or not in accordance with a time variation in current just after the application the current to the coil 20 and for issuing a warning. Accordingly, sticking condition of the solenoid valve 18 is detected in accordance with a transient responsiveness of current at the beginning of energization of the coil 10.

123 Inspecting method of four-way valve JP18275183 1983-09-30 JPS6073430A 1985-04-25 YOSHIDA SHIYOUICHI; MISAWA MASARU
PURPOSE:To inspect whether a four-way valve operates securely or not easily and accurately after the valve is manufactured by inspecting the flow rate at a bleed hole is within specific ranges to the water leakage and flow rate of a pilot valve. CONSTITUTION:A curve (a) shows the bleed hole flow rate of an X side, and a curve (b) shows the bleed hole minimum value of a pilot valve leakage MAXY side. When the bleed hole flow rate becomes about one-third as large as the pilot valve flow rate, i.e. when an X-side bleed hole flow ratio becomes 0.35, operating pressure rises almost to a standard (1.5kg/cm<2>g). The four-way valve operates securely under the 1st and the 2nd horizontal lines A and D (hatched area) in a figure, and operates insufficiently over the horizontal lines. For the purpose, the propriety of the four-way valve is discriminated by inspecting whether the X-side bleed flow rate is <=1/3 as large the pilot valve flow rate and the Y-side bleed hole flow rate is >=20 times the pilot valve leakage.
124 Method of testing valve JP12213983 1983-07-05 JPS6014676A 1985-01-25 YAMAZAKI TAKESHI; SATOU YOSHIROU
PURPOSE:To make it possible to carry out the flowing test of an actual-valve with no use of a valve body, by forming the passage of the valve body with the use of die members respectively having recessed parts for forming a passage wall, and by passing liquid through the passage after a trim part is disposed in this passage. CONSTITUTION:A passage 5 in a valve body is defined between a pair of die members 1 respectively having recessed sections 2, for forming the passage wall of the valve body. Further a trim part is disposed in the passage 5. With these die members 1 and the trim part the passage which is equivalent to the actual passage formed in a cast valve body, is obtained. Accordingly, when liquid is made flow through the passage 5 between the die members 1, the flowing test of the actual valve may be made.

The stroke of the vibrator, the load, a test chamber pressure, etc. are recorded, and reduction of the weight, the damage condition of a contacting face, etc. after the test are observed to evaluate the durability. Thus, the endurance test of test pieces X and Y is performed in a short time with a low cost.

131 TIME-SERIES ANALYTICS FOR CONTROL VALVE HEALTH ASSESSMENT US15332563 2016-10-24 US20180112795A1 2018-04-26 Shawn W. Anderson
Securing communications from a process plant to a remote system includes a data diode disposed there between that allows data to egress from the plant but prevents ingress of data into the plant and its associated systems. Process plant data from the secure communications is then analyzed to detect conditions occurring at process plant entities in the process plant using various machine learning techniques. When the process plant entity is a valve, the mode of operation for the valve is determined and a different analysis is applied for each mode in which a valve operates. Additionally, the process plant data for each valve is compared to other valves in the same process plant, enterprise, industry, etc. Accordingly, the health of each of the valves is ranked relative to each other and the process plant data for each valve is displayed in a side-by-side comparison.

In the first method, a force sensor is placed in the valve in such a way as to detect changes in the impact force of the plunger against the solenoid valve body or coil housing (depending upon the direction of movement of the plunger upon application of the electric current/magnetic field). A second method is provided which makes use of an accelerometer placed in such a way as to detect changes in the response of the plunger to the application of the magnetic field.
136 Methods to improve online diagnostics of valve assemblies on a process line and implementation thereof US14134474 2013-12-19 US09810345B2 2017-11-07 Robert Claude Prescott; Xianren Kong
Embodiments of a method and a system, which is configured to implement the method, to process data from one or more valve assemblies found e.g., on a process line. These embodiments can generate a listing that identifies how network/system bandwidth is allocated for the collection of data from the valve assemblies. The embodiments can also process the data to re-arrange the valve assemblies in the listing to better allocate the network/system bandwidth to certain ones of the valve assemblies that require more data to properly assess the operation of the valve assembly. In this way, further diagnostics using the data can identify any changes in operation of the valve assemblies that might be detrimental to the valve assembly and/or the process line in general.
