Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model negative pressure automatic drainage device.
Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model embodiment is discussed in detail.
Refering to fig. 1, the utility model provides a kind of negative pressure automatic drainage device, is mounted on methane gas extraction pipeline 1 comprising
The top of water tank 12, water tank 12 is equipped with seal cover board, and the lower section of 12 side wall of water tank is equipped with drainage cell, the top of 12 side wall of water tank
It is equipped with inlet unit, negative-pressure balancing pipe 4 and atmosphere duct 5 successively from bottom to up, inlet unit, negative-pressure balancing pipe 4 are and gas
Extraction pipeline 1 is connected to, and is equipped with atmosphere duct check valve in atmosphere duct 5, water tank 12 is internally provided with for open-top air pipe
The mandril 8 of road check valve, mandril 8 are equipped with buoy 7, and the side on 8 top of mandril is fixed with fulcrum bearing, and fulcrum bearing is equipped with energy
The magnet of negative-pressure balancing pipe 4 is sucked, magnet is equipped with gasket, and the lower section of 12 inner wall of water tank is equipped with impeller 11.
Inlet unit includes water inlet pipe 2 and the water inlet pipe check valve 3 in water inlet pipe 2, and drainage cell includes water outlet
Pipe 9 and door 10 mounted on 9 end of outlet pipe, the right end of door 10 are fixed with connector, and one end of connector is hinged on
The top of 9 side wall of outlet pipe, connector are arc, and 8 lower section of mandril is provided with ejector rod base 6, and the lower end slide fit of mandril 8 is in mandril
Inside pedestal 6.
Its working principle is that：It is installed on methane gas extraction pipeline, when low-lying pipeline section has ponding, ponding passes through water inlet
Pipe check valve enters water tank along water inlet pipe, and with the increase of quantity of water in water tank, buoy slowly floats, until the magnetic in fulcrum bearing
Iron is adsorbed on negative-pressure balancing pipe, and the gasket on magnet seals negative-pressure balancing pipe, while the open-top atmosphere duct of mandril is unidirectional
Valve so that be normal pressure in water tank, water inlet pipe check valve seals water inlet pipe under atmospheric pressure, and door is in the effect of hydraulic pressure
Lower unlatching, as ponding flows so that propeller rotational drives flow to be discharged to the residue of water tank bottom and dirt along outlet pipe
Outside tailrace, Auto-drainage is completed, and under the influence of conducting oneself with dignity with the decline of water level in water tank and buoy, magnet is flat with negative pressure
The pipe that weighs detaches, and negative-pressure balancing pipe is opened while buoy declines, and the atmosphere duct check valve inside atmosphere duct is closed, in negative pressure
Under the action of close door, water tank is connected to methane gas extraction pipeline again, buoy again be in original state, realize cycle drainage
Slag.
