Large caliber heat meter test bed capable of checking multiple meters

Abstract

The invention discloses a large caliber heat meter test bed capable of checking multiple meters. The large caliber heat meter test bed comprises a pipeline bracket, a meter clamping pipe section and a protection cover; the large caliber heat meter test bed is characterized in that: a pressure cylinder is hung out of the meter clamping section; a sliding wheel is arranged on the protection cover; the protection cover is made of organic glass; a guiderail where the sliding wheel can glide is arranged on the pipeline bracket; when the meter is clamped, the meter clamping pipe section matched with the meter to be tested is selected; the meter clamping pipe section is placed on the pipeline bracket; a water inlet pipe section hole and a water outlet pipe section hole of each heat meter can be judged according to the water flow direction marked on the heat meter; the heat meter to be tested is arranged on the test bed according to the water flow direction arranged in a calibrating device; the meter clamping pipe section is connected with the corresponding pipe section hole of the heat meter; the heat meter and the meter clamping pipe section can be clamped by opening an air cylinder reversing valve on the pipeline bracket; the heat meter to be tested and the meter clamping pipe sections can be clamped in turn according to the method; and the protection cover is glided to the heat meter to be tested. The meter clamping machine has an in-place detection function, and after the meter is clamped completely, an in-place detector transmits signals to an upper computer.

Description

(1) Technical field [0001] The invention relates to the verification field of heat meters, in particular to a large-diameter heat meter test bench capable of verifying multiple meters. (2) Background technology [0002] With the continuous promotion of my country's urban heating system reform pilots, the development of domestic heat meters is very rapid. In order to adapt to the factory inspection of heat meters by manufacturers of heat meters, and also to adapt to the first inspection of heat meters by heat supply companies and quality management departments Mandatory verification, the existing heat meter verification generally adopts a complete set of devices for verification. At present, the number of existing large-caliber heat meter verification devices in my country is small, and there are the following deficiencies: In the heat meter verification device, the clamping pipe section of the traditional large-caliber heat meter test bench is relatively heavy and long. Fix a...
