Description
Technical field
The utility model relates to a kind of automatic drain structure of vacuum pump more particularly to vacuum pump under vacuum conditions.
Background technique
Currently, needing to stop the operation of vacuum pump when vacuum pump has more liquid under vacuum conditions, liquid can be arranged
Out.Therefore, a kind of automatic drain structure that liquid can be discharged without shutdown is researched and developed, it is urgently to be resolved to become those skilled in the art
The problem of.
Summary of the invention
The utility model is to provide a kind of automatic drain knot of vacuum pump under vacuum conditions to solve above-mentioned deficiency
Structure.
The above-mentioned purpose of the utility model is realized by technical solution below: a kind of vacuum pump is under vacuum conditions
Automatic drain structure, including No.1 vacuum tank, No. two vacuum tanks, No.1 pneumatic operated valve, No. two pneumatic operated valves and No. three pneumatic operated valves, it is described
The air entry of connection equipment general pipeline and the exhaust outlet of connection vacuum pump, the No.1 vacuum pot bottom are equipped at the top of No.1 vacuum tank
It being connected at the top of No. two vacuum tanks by connecting pipe, connecting pipe is equipped with No.1 pneumatic operated valve, meanwhile, No.1 vacuum pot bottom
Equipped with No.1 sewage pipe, No.1 sewage pipe is equipped with No.1 manual blowdown valve；
No. two vacuum tank bottom sides are equipped with drain pipe, and drain pipe is equipped with No. two pneumatic operated valves, No. two vacuum tank bottoms
The portion other side is equipped with No. two sewage pipes, and No. two sewage pipes are equipped with No. two manual blowdown valves；Ventilation is equipped at the top of No. two vacuum tanks
Pipe, snorkel are equipped with No. three pneumatic operated valves.
Further, the tank skin of No. two vacuum tanks is equipped with magnetic double level gauge.
Working principle of the utility model is: No. two pneumatic operated valves and No. three pneumatic operated valves are closed state, No.1 when equipment is run
Pneumatic operated valve is open state.No. two vacuum tanks can be automatically flowed by No.1 pneumatic operated valve after No.1 vacuum tank sucks liquid.When
When No. two vacuum tank liquid levels reach setting liquid level, magnetic double level gauge gives signal control cabinet, and control cabinet provides closing No.1 at this time
Valve opens No. two pneumatic operated valves and No. three pneumatic valve signal liquid are automatically drained out from No. two operated pneumatic valves.After emptying rate of liquid, magnetic
Turnover panel can issue signal, close No. two pneumatic operated valves and No. three pneumatic operated valves at this time, and No.1 pneumatic operated valve is opened.
If liquid to flow into lower can not oil (gas) filling device, No. two pneumatic operated valves automatically open and can flow out.As the defeated need of liquid are defeated
When sending eminence, the pneumatic diaphragm pump of No. two pneumatic operated valves of a connection need to be increased here.
The utility model compared with prior art the advantages of be: solve under vacuum state when having more liquid, vacuum pump is not
Liquid is discharged automatically in the case where shutdown.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail below with reference to embodiment.
As shown in Figure 1, a kind of automatic drain structure of vacuum pump under vacuum conditions, including No.1 vacuum tank 1, two is very
It is total to be equipped with connection equipment at the top of the No.1 vacuum tank 1 for slack tank 2,3, No. two pneumatic operated valves 4 of No.1 pneumatic operated valve and No. three pneumatic operated valves 5
The air entry 6 of pipe and the exhaust outlet 7 of connection vacuum pump, 1 bottom of No.1 vacuum tank is connected to No. two very by connecting pipe 8
2 top of slack tank, connecting pipe 8 are equipped with No.1 pneumatic operated valve 3, meanwhile, 1 bottom of No.1 vacuum tank is equipped with No.1 sewage pipe 9, No.1
Sewage pipe 9 is equipped with No.1 manual blowdown valve 10；
2 bottom side of No. two vacuum tanks is equipped with drain pipe 11, and drain pipe 11 is equipped with No. two pneumatic operated valves 4, and No. two true
The 2 bottom other side of slack tank is equipped with No. two sewage pipes 12, and No. two sewage pipes 12 are equipped with No. two manual blowdown valves 13；No. two vacuum tanks
2 tops are equipped with snorkel 14, and snorkel 14 is equipped with No. three pneumatic operated valves 5.
Further, the tank skin of No. two vacuum tanks 2 is equipped with magnetic double level gauge 15.
Working principle of the utility model is: when equipment is run, No. two pneumatic operated valves 4 and No. three pneumatic operated valves 5 are closed states, one
Number pneumatic operated valve 3 is open state.No. two vacuum can be automatically flowed by No.1 pneumatic operated valve 3 after No.1 vacuum tank 1 sucks liquid
Tank 2.When No. two 2 liquid levels of vacuum tank reach setting liquid level, magnetic double level gauge 15 gives signal control cabinet, and control cabinet provides at this time
It closes No.1 valve No. two pneumatic operated valves 4 of opening and No. three 5 signal liquid of pneumatic operated valve is automatically drained out from No. two pneumatic operated valve 4.Work as liquid
After body emptying, magnetic turning plate can issue signal, close No. two pneumatic operated valves 4 and No. three pneumatic operated valves 5 at this time, and No.1 pneumatic operated valve 3 is opened.
If liquid to flow into lower can not oil (gas) filling device, No. two pneumatic operated valves 4 automatically open and can flow out.As the defeated need of liquid are defeated
When sending eminence, the pneumatic diaphragm pump of No. two pneumatic operated valves 4 of a connection need to be increased here.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
