Description
Technical field
The utility model belongs to pressure fan equipment technical field, and in particular to a kind of pressure fan oil gas tank dropping equipment.
Background technique
Pressure fan is the essential equipment of underground coal mine work, compressed air caused by it, to drive pneumatic dress
The pneumatic tools such as rock machine, and in pressure fan use process, need maintenance down to safeguard.
As shown in Figure 1 be existing pressure fan schematic diagram, when pressure fan in use, need maintenance down to safeguard, this
When oil gas tank 1 in pressure be greater than 0.4Mpa, and the pressure of pressure fan head 4 is less than 0.4Mpa, due to pressure in oil gas tank 1 and pressure
The presence of 4 pressure difference of blower head, will cause the non-return valve on oil return pipe 3 cannot normally open, gas mixture in oil gas tank 1
Pressure fan head 4 is flowed backward to by air inlet pipe, is sprayed from air inlet, recycle oil is caused to waste.
Utility model content
In order to overcome the technical drawbacks described above, the purpose of the utility model is to provide a kind of pressure fan oil gas tank dropping equipment,
Therefore it avoids pressure fan oil gas tank 1 from occurring flowing backwards phenomenon, realizes the purpose for saving recycle oil.
The technical solution that the utility model is taken are as follows:
A kind of pressure fan oil gas tank dropping equipment, including oil gas tank 1 and oil return pipe 3 further include relief tube 6, threeway connection
Pipe 5 and hand-operated valve 7；The first outlet of three-limb tube 5 is connected at the top of oil gas tank 1；The second outlet of three-limb tube 5 connects back to
Oil pipe 3, the third outlet connection relief tube 6 on three-limb tube road 5；6 bottom of relief tube is connected with hand-operated valve 7.
The utility model has the beneficial effects that:
(1) structure is simple, occupies little space, low in cost, securely and reliably, economic and practical, easy to operate, is easy to extensive
It promotes and uses；
(2) the utility model can effectively avoid oil gas tank 1 occur oil gas flow backwards phenomenon, save recycle oil；By adjusting hand
Dynamic valve 7 switchs, and realizes pressure release flow control, has and operates convenient and fast outstanding feature, and safety coefficient is high.
Detailed description of the invention
Fig. 1 is existing pressure fan schematic diagram；
Fig. 2 is schematic diagram after the repacking of the utility model pressure fan oil gas tank.
Wherein: 1- oil gas tank 2- safety valve 3- oil return pipe 4- pressure fan head 5- three-limb tube 6- relief tube 7- hand-operated valve
Specific embodiment
Referring to Fig. 2, a kind of pressure fan oil gas tank dropping equipment, which includes oil gas tank 1 and oil return pipe 3, is also wrapped
Include relief tube 6, three-limb tube 5 and hand-operated valve 7；The first outlet of three-limb tube 5 is connected at the top of oil gas tank 1；Threeway connection
The second outlet of pipe 5 connects oil return pipe 3, the third outlet connection relief tube 6 of three-limb tube 5；6 bottom of relief tube is connected with hand
Dynamic valve 7.
When pressure fan in use, need maintenance down to safeguard, hand-operated valve 7 be opened manually, make the pressure in oil gas tank 1
Power is by 6 pressure release of relief tube, until the pressure in oil gas tank 1 is close with 4 pressure of pressure fan head；It is carried out according to maintenance repair step
Subsequent service work.
The utility model structure is simple, occupies little space, low in cost, securely and reliably, economic and practical, easy to operate, easily
In large-scale promotion and use；By the way that three-limb tube road will be repacked at the safety valve 2 of existing pressure fan oil gas tank 1, in pipe
Road is additionally arranged at the bottom a hand-operated valve 7.In use, when needing maintenance down to safeguard, by opening hand-operated valve 7, make oil gas
Pressure reduction in tank 1, until opening the non-return valve on oil return pipe 3 when suitable with 4 pressure of pressure fan head and carrying out normal maintenance dimension
Nurse makees.It can effectively avoid oil gas tank 1 and oil gas refluence phenomenon occur, save recycle oil；By adjusting the switch of hand-operated valve 7, realize
Pressure release flow control, has and operates convenient and fast outstanding feature, and safety coefficient is high.
The foregoing is merely the utility model preferred embodiments, and therefore it does not limit the scope of the patent of the utility model,
All equivalent structure or equivalent flow shifts that can be done using the utility model specification and accompanying drawing content, or directly or
It connects and is used in other related technical areas, be also included in the patent protection scope of the utility model.
