Abstract
The utility model discloses an automatic test device for valve dynamic performance, including a blower, a pressure hole, a valve connection upstream section, a valve connection downstream section and a current collector. The valve connection upstream section and the blower are equipped on the front end of the valve measured. The valve connection downstream section and the current collector are equipped on the back end of the valve measured. The pressure holes are provided on the valve connection upstream section, the valve connection downstream section and the current collector. The blower adopts mix-flow type, with a blower inlet section on the front. A damping screen is equipped on the valve connection downstream section and the current collector. The blower inlet section is in trumpet type. The good effect of the utility model is frequency conversion adjustment technique adoption, convenient flow regulation, low noise, less area occupation and high measuring precision.
Description
Affiliated technical field
The utility model relates to a kind of proving installation, especially a kind of device that is used for the detection system discharge characteristic.
Background technology
Be used for measuring the device proving installations that adopt mechanical industry standard JB/T7228-94 appendix to recommend of valve and collecting smoke dust from coke oven device systems discharge characteristic at present more, its wind regime adopts common centrifugal blower, between valve connection Upstream section and blower fan, threeway and push-pull valve are housed, aperture by the manual adjustment push-pull valve is regulated flow, device exists bulky, noise is big, regulates difficulty, the deficiency that the test degree is low.
Summary of the invention
Bulky for overcoming existing proving installation, regulate difficulty, the deficiency that the test degree is low, the utility model provides the valve dynamic property that a kind of flow regulation is simple, easy to use, measuring accuracy is high automatic testing equipment.
The technical scheme that its technical matters of solution of the present utility model adopts is a kind of valve dynamic property automatic testing equipment, comprise blower fan, pressure tap, valve connects Upstream section, valve connects tract, current collector, front end at tested valve is equipped with valve connection Upstream section and blower fan, valve is housed in the rear end of tested valve connects tract and current collector, connect Upstream section at valve, valve connects on tract and the current collector pressure tap, blower fan adopts flow-mixing blower fan, front end at blower fan also is equipped with the fans entrance section, connects between tract and the current collector at valve honeycomb screen also is housed.The fans entrance section is horn-like.Owing to adopted flow-mixing blower fan, the frequency by external frequency converter is regulated blower fan can realize the adjusting of flow, wind speed easily, and system noise is low; In addition owing to cancelled threeway and push-pull valve, compared with prior art can reduce the length of 5 times pipe diameter, saved the occupation of land space, the honeycomb screen of fans entrance section of adorning at the front end of blower fan and exit dress, can make through the air velocity distribution of equipment under test uniform and stable, improve measuring accuracy greatly, shortened test period.
The beneficial effects of the utility model are to have adopted frequency conversion to adjust art, and it is convenient and swift to regulate flow, the measuring accuracy height, noise is low, take up an area of little, measuring accuracy is high.
