Abstract
The utility model provides a gas meter ageing simulation testing machine. A gas meter constant-temperature detection area is divided in a machine body, a gas meter input pipeline, a gas meter output pipeline and a gas meter dial sensing detector are arranged in the constant-temperature detection area, a circulation air pump and a connecting pipeline of the circulation air pump are further arranged in the machine body, the circulation air pump connecting pipeline is connected with the gas meter input pipeline and the gas meter output pipeline via control valves to form a circulation loop, and the constant-temperature detection area is provided with a temperature adjusting device. The technical scheme of the gas meter ageing simulation testing machine meets and can exceed the requirements of ageing test standard of professional technical standard to gas meters, particularly film-type gas meters, and is convenient for technical staff to master gas meter testing data closer to actual dynamic running to know gas meter technical performance.
Description
Technical field
The utility model relates to the test unit of the aging runnability of gas meter, flow meter.
Background technology
Gas meter, flow meter need carry out high and low temperature test, just aging test by professional technique standards such as national technical standards.The present method of inspection is carried out the detection of correlation technique index thereafter again with the time of an appointment in the static temperature space of depositing in appointment of gas meter, flow meter model machine to the gas meter, flow meter model machine, contrast, the performance change of gas meter, flow meter relatively.The resting state test method can't embody at all the gas meter, flow meter complete machine in the actual motion state, the truth after the hot operation especially, technology people also are difficult to clearly understand thus the real technology performance of gas meter, flow meter.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of aging simulation test machine of gas meter, flow meter of more real simulated gas meter, flow meter test condition.The gas meter, flow meter that the utility model the provides simulation test machine technical scheme that wears out, its major technique content is: a kind of gas meter, flow meter simulation test machine that wears out, divide in the body and be separated with gas meter, flow meter Constant Temperature Detection zone, be provided with gas meter, flow meter input, output pipe and gas meter, flow meter dial plate sensor monitoring head in this Constant Temperature Detection zone, also be provided with circulation air pump and connecting line thereof in the body, circulation air pump connecting line connects and composes closed circuit through operation valve and gas meter, flow meter input, output pipe, and the Constant Temperature Detection zone is provided with temperature control equipment.
In above-mentioned overall technical architecture, circulation air pump connecting line navigates within the corresponding valve road that is connected to multi-way control valve in the thermoregulation mechanism.
The aging simulation test machine of the disclosed gas meter, flow meter of the utility model satisfies, also can surpass the professional technique standard to gas meter, flow meter, especially diaphragm gas meter aging test standard-required, it can be gas meter, flow meter a dry run state that is used to carry out the aging test test is provided, thereby the gas meter, flow meter test figure that the technician can be grasped more be close to actual dynamic operation is understood the gas meter, flow meter technical feature.
