Abstract
The utility model belongs to the technical field of experiments, and relates to an integrated single-outlet comprehensive detection platform for series flow and leakage of a valve. An air source of the detection platform passes through a filter to reach an air source pressure-reducing valve; an outlet of the pressure-reducing valve is provided with a pressure indicator which is connected with a shutoff valve; the shutoff valve is connected with a mass flowmeter which is connected with a system outlet; and a pressure indicator is arranged in front of the system outlet. The detection platform adopts the mass flowmeter; a single mass flowmeter is configured, and the turndown ratio of a system can reach 100 times that of the prior art; and at most two mass flowmeters can meet the requirement of comprehensive detection of the series flow and leakage of the valve. The detection platform is provided with only one interface for detecting the flow, only one connection mode is adopted in the process of detecting the series flow and leakage of the valve and the whole detection process can be completed after once connection. The detection platform adopts a mode of connecting a pressure regulating valve later, so that the mass flowmeter works under a fixed working condition and is facilitated to meter the working condition, and the detection accuracy is ensured.
Description
Technical field
The utility model belongs to the experimental technique field, relates to a kind of integrated, single outlet valve crossfire amount, amount of leakage combined test stand.
Background technology
The equipment that is used for valve air-flow crossfire amount, amount of leakage detection at present is owing to adopt the sub-flowmeter survey flow of many table flotations, flowmeter places tested valve back when measuring valve crossfire amount, flowmeter is operated in atmospheric pressure state, flowmeter places tested valve front when measuring the valve amount of leakage, flowmeter is operated in tested valve working pressure state, usually it is different with the amount of leakage installation form to dispose 6 to 8 flowmeters and crossfire amount, causes that measuring error is big, measuring process is loaded down with trivial details.
Summary of the invention
The purpose of this utility model provides integrated, single outlet valve crossfire amount, the amount of leakage combined test stand that a kind of measuring error is little, measuring process is simple and direct.Technical solution of the present utility model is, the source of the gas of monitor station arrives the source of the gas reduction valve through filter, the reduction valve outlet is provided with the pressure indication, the pressure indication is connected with shut-off valve, shut-off valve links to each other with mass flowmeter, mass flowmeter links to each other with system outlet by pressure regulator valve, and the pressure indication is set before the system outlet.Advantage that the utlity model has and beneficial effect, integrated, single outlet valve crossfire amount, amount of leakage combined test stand adopt mass flowmeter, separate unit flowmeter configuration-system just can reach 100 times range ratio, and common one, the configuration of maximum two mass flowmeters just can satisfy the comprehensive detection of valve crossfire amount, amount of leakage.The utility model has only one to detect the flow interface, and detection valve crossfire amount, amount of leakage process also have only a kind of type of attachment, once connect and just can finish whole testing processes.Connect the form of pressure regulator valve after the utility model adopts, make mass flowmeter be operated in fixedly under the operating mode, be convenient to the operating mode metering of mass flowmeter, guarantee the accuracy of detection.
