FIG. 1 is a schematic view showing the structure of an automatic back-blowing antifreeze drainage apparatus according to embodiment 1;
the water heater comprises a water tank 101, a pressure water storage tank 102, a heater 103, a first valve 104, a second valve 105, a water inlet one-way valve 106, a second electromagnetic air valve 107, a water quantity regulating valve 108, a water injection pipe 109, a gas storage tank 110 and a first electromagnetic air valve 111.
Detailed Description
Example 1
The utility model discloses an automatic blowback drainage device that prevents frostbite, including water tank 101, pressure water storage tank 102, gas holder 110, the check valve 106 that intakes, heater 103, first valve 104, second valve 105, water injection pipe 109, water regulation valve 108, first electromagnetism pneumatic valve 111 and second electromagnetism pneumatic valve 107.
The pressure water storage tank 102 is connected with the heater 103, one port of the pressure water storage tank 102 is connected with the first electromagnetic air valve 111, the other port of the pressure water storage tank 102 is connected with one end of the water inlet one-way valve, the first electromagnetic air valve 111 is connected with the air storage tank 110, the other end of the water inlet one-way valve 106 is connected with one end of the second valve 105, the other end of the second valve 105 is connected with one water inlet and outlet of the water tank 101, and the other water inlet and outlet of the water tank 101 is provided with the first valve 104; the third port of the water inlet check valve 106 is connected to one end of the water quantity regulating valve 108 through a second solenoid valve 107, and the other end of the water quantity regulating valve 108 is connected to a water filling pipe 109.
In this embodiment, the air storage tank 110 is an air bag, the first electromagnetic air valve 111 is a two-position three-way electromagnetic air valve, the first valve 104 and the second valve 105 are ball valves, and the second electromagnetic air valve 107 is a two-position three-way electromagnetic air valve.
The automatic back-blowing anti-freezing drainage device is used for drilling and perforating under a rotary drill and has the following working principle:
when the first electromagnetic air valve 111 and the second electromagnetic air valve 107 are in a power-off state, air is not supplied into the pressure water storage tank 102, and water in the water tank 101 fills the pressure water storage tank 102 with water through the water inlet check valve 106 under the action of internal pressure.
If the electromagnetic valve is electrified by operation, gas enters the pressure water storage tank 102 from the gas storage tank 110, at the moment, the valve core of the water inlet one-way valve 106 automatically closes the water inlet, water enters the water injection pipe 109 through the water inlet one-way valve 106 and the water quantity regulating valve 108 in sequence under the action of pressure, the water injection pipe 109 is also electrified with pressure, and after the water and compressed air are mixed, a drill rod is conveyed to the bottom of a hole through the rotary main shaft.
