Abstract
The invention relates to a ventilation and dynamic characteristic detection platform for an explosion-proof overpressure exhaust valve. The ventilation and dynamic characteristic detection platform comprises a pressure sensor, a plenum chamber, a ball valve, a draught fan support, a variable frequency draught fan and the exhaust valve, wherein the variable frequency draught fan is installed on the draught fan support, the end portion of the variable frequency draught fan is connected with the plenum chamber, the exhaust valve is installed on one side of the plenum chamber, the ball valve is installed on one side of the plenum chamber, and the pressure sensor is installed on the end portion of the ball valve. The ventilation and dynamic characteristic detection platform is simple in structure, detection is convenient, and high practicability is achieved.
Description
Technical field
The present invention relates to industrial detection technical field, relate in particular to Antiexplosive overpressure air exhaust valve ventilation kinematic behavior detection platform.
Background technology
When needs carry out gas filtration ventilation, 30-50Pa superpressure must be caused and keep in protection works inside, and now the valve gap of overpressure exhaust valve is automatically opened under the effect of superpressure, to get rid of the poison gas in gas defence passage.When isolated protection body is carried out in wartime requirement, with manually, by valve gap locking, now overpressure exhaust valve has protection airtight function; Adopting Antiexplosive overpressure air exhaust valve, can directly replace the exhaust system that is comprised of former common explosion wave prevention active door and automatic vent wave absorption lively atmosphere and automatic exhaust valve, also can do separately the use of superpressure drain tap, is indispensable safeguard in modern protection works; And there are two kinds of functions: 1, borrow its inner air and outer air pressure differential automatic open close valve to guarantee the well-ventilated of engineering inside simultaneously; 2,, when explosion wave arrives, valve moment closes automatically, plays explosion-wave-preventing effect; Therefore developing a kind of platform that detects exhaust valve performance is necessary.
Summary of the invention
The object of this invention is to provide Antiexplosive overpressure air exhaust valve ventilation kinematic behavior detection platform, by the present invention, exhaust valve is detected, detect exhaust valve air permeability and leakproofness.
The technical scheme that the present invention solves the problems of the technologies described above is as follows:
Antiexplosive overpressure air exhaust valve ventilation kinematic behavior detection platform, comprise pressure transducer, plenum chamber, ball valve, fan supporter, frequency conversion fan and exhaust valve, described frequency conversion fan is arranged on fan supporter, and the end of frequency conversion fan is connected with plenum chamber, described plenum chamber one side is provided with exhaust valve, described quiet
Press case one side that ball valve is installed, the end of described ball valve is provided with pressure transducer.
On the basis of technique scheme, the present invention can also do following improvement.
Further, it also comprises flowmeter, and described flowmeter is arranged between frequency conversion fan and plenum chamber;
Further, described flow is counted metallic rotameter.
The invention has the beneficial effects as follows:
1. by the cooperation of frequency conversion fan and plenum chamber, can detect the performance of exhaust valve, judge that it can realize automatic vent;
2. by flowmeter, can detect under different air pressure the air leakage of this device.
3. the present invention is simple in structure, and cost is low, and measures conveniently.
