[CN 201621277811.7] Hydraulic Mechanism of Water Meter Verification Device Clamping Checked Meter
[CN 201621277811.7] Title of hydraulic mechanism for clamping the checked meter by the water meter verification device: Application number of hydraulic mechanism for clamping the checked meter by the water meter verification device: CN 201621277811.7 Applicant: Dandong Yibang Metrology Instrument Co., Ltd. Application Date: 2016-11-26 Patent Type: Utility Model This utility model relates to a hydraulic mechanism for clamping the checked meter by the water meter verification device, with epitope simulation wells, the epitope simulation well is equipped with a test meter, the upper edge of the epitope simulation well is provided with a lock-press flip cover, and the two sides of the lock-press flip cover are respectively connected to the power cylinder through a clamping linkage mechanism and a synchronous auxiliary mechanism; The lock-press flip cover has a cover body, which extends horizontally from symmetrical positions on both sides of the cover body. The cover body is hollow pie-shaped, the internal shape of the round pie is matched with the shape of the pressed part of the surface to be inspected, and the opening pressure plate is provided with a V-shaped groove. The hydraulic mechanism for clamping the checked meter of the water meter verification device of the utility model can overcome the shortcomings of the ordinary high-pressure water injection meter hydraulic meter clamp. The mechanism can improve the safety of the meter clamp, has a high degree of automation, effectively improves work efficiency, and reduces The labor intensity of the staff is suitable for the verification and calibration of high-pressure water injection meters under various conditions.
