The utility model for achieving the above object, the main technical schemes of taking is: at original air diaphragms pump (membrane pump with pneumatic drive) afterwards, set up a safety governor, when the barrier film of air diaphragms pump is damaged, power gas source can entrained liquids be discharged, and carries out gas-liquid separation by the safety governor of setting up, and source of the gas is turn-offed in safety control, the air diaphragms pump is quit work automatically, guarantee the safety of production scene.
The utility model provides a kind of air diaphragms pump diaphragm leakage safety governor, and this safety governor comprises rotation gas-liquid separator, push rod, source of the gas control valve, gas discharge pipe, anti-overflow device, fluid-tight device;
Described rotation gas-liquid separator has the import of a leakage safety governor gas-liquid, links to each other with the air diaphragms pump exhaust inlet of air diaphragms pump by pipeline; Establish a ball float below rotation gas-liquid separator inside, ball float can promote push rod when rising and close the source of the gas control valve; The outside on rotation gas-liquid separator top is connected with gas discharge pipe, anti-overflow device and fluid-tight device in turn;
Described source of the gas control valve links to each other with the air diaphragms pump gas source inlet of air diaphragms pump, the Kai Heguan of control gas source inlet.
For avoiding noise excessive, the utility model also arranges a baffler between anti-overflow device and fluid-tight device.
Convenient controlled for the liquid discharge that makes rotation gas-liquid separator below, the utility model is also at the blowdown valve of arranged outside that rotates the gas-liquid separator bottom.
Use air diaphragms pump diaphragm leakage safety governor of the present utility model, the method that leakage is controlled to the air diaphragms pump diaphragm may further comprise the steps:
A, liquid material enter the air diaphragms pump, open air diaphragms pump gas source inlet by the source of the gas control valve, and source of the gas enters the air diaphragms pump, and the barrier film of air diaphragms pump is moved reciprocatingly, and normally carry liquid material;
B, the barrier film breakage in the air diaphragms pump, leakage, gas mixes liquid material, discharges from the air diaphragms pump exhaust inlet, enters the rotation gas-liquid separator by the import of leakage safety governor gas-liquid;
C, in the rotation gas-liquid separator, the specific gravity of gas after the gas-liquid separation is light toward rising, and discharges through gas discharge pipe; Liquid specific gravity after the gas-liquid separation is rotating the gas-liquid separator bottom than resedimentation, liquid level rising generation buoyancy when the bottom rises ball float, promote push rod and close the source of the gas control valve, the source of the gas control valve is closed air diaphragms pump gas source inlet, and the air diaphragms pump is quit work.
After the air diaphragms pump quits work, can further carry out coherence check and the maintenance of the breakage of air diaphragms pump diaphragm.
The effect of anti-overflow device is to stop gas, liquid may produce foam when separating to overflow, and the effect of fluid-tight device is purification of exhaust gas.
After maintenance finishes, open blowdown valve, discharge the liquid in the rotation gas-liquid separator, ball float descends, and unclamps push rod, and the source of the gas control valve is opened air diaphragms pump gas source inlet, air diaphragms pump proper functioning.
Good effect behind enforcement the utility model:
Mechanical float-ball type termination of pumping controlling method of the present utility model, effectively diaphragm pump is advanced to revolve air cylinder because of the damaged air trapping that is mixed with the leakage liquid material that produces of barrier film, utilize hydrometer method that gas, liquid are separated, the leakage liquid of utilize assembling promotes the technology that ball float is closed air diaphragms pump source of the gas, the air diaphragms pump has been implemented the closed loop of " starting---normal operation---fault (barrier film breakage)---termination of pumping control " each link and has been controlled automatically.
On the other hand, the utility model has effectively overcome the traditional electric control method very big harmfulness that exist, that may cause security incident of use in the inflammable and explosive environment of chemical industry.
The utility model function-stable, good manufacturability, especially Safety performance is reliable, is worth using in inflammable and explosive environment the production field of air diaphragms pump to apply (as fields such as chemical industry, petrochemical industry, coating, mining).
