Abstract
The utility model discloses an explosion-proof control cabinet positive pressure cooling device, comprising a positive pressure controller (1), a decompression valve (2), a cabinet cooler (3), a compressed gas total inlet valve (4), a three way connection (5), a cabinet cooler compressed gas inlet valve (6) and a control cabinet (7); the positive pressure controller (1) is installed on a right lower side of the control cabinet (7); the decompression valve (2) is installed on a left upper side of the control cabinet (7); the cabinet cooler (3) is installed on the top of the control cabinet (7); the cabinet cooler (3) is in connection with the cabinet cooler compressed gas inlet valve (6); the positive pressure controller (1), the cabinet cooler compressed gas inlet valve (6) and the compressed gas total inlet valve (4) are respectively in connection with the three way connection (5). A work power supply does not need to be provided for on-site work, which is suitable for work under high temperature environments and can raise on-site work security; the positive pressure controller and the cabinet cooler have the advantages of a smaller size and a simple structure, are easy to install and convenient to operate and control, can meanwhile raise economical efficiency and reduce maintenance costs and are convenient to dismount and replace.
Description
Technical field
The utility model relates to the gas compressor set explosion proof control case, a kind of novel gas compressor set explosion proof control case malleation cooling device of specific design.
Background technology
At present, the supporting positive pressure controller of gas compressor set positive pressure explosion-proof cabinet generally needs to provide working power both at home and abroad, and the explosion proof control case that causes being applied to the deathtrap has been introduced unsafe factor again; Secondly, in the torrid areas, particularly summer, cause that owing to ambient temperature is high the explosion proof control case internal temperature is too high, affect the normal working performance of electric component, even electric component produces because of high temperature unusually, cause compressor bank cancel closedown fault.Current, generally adopt air conditioner refrigerating for the type of cooling of control cubicle, the modes such as water circulation cooling exist that application cost is high, system complex, installation inconvenience and the problems such as difficult in maintenance.
The utility model content
The purpose of this utility model is exactly the defective that exists for existing design concept, and a kind of rational explosion proof control case malleation cooling device is provided.
For achieving the above object, the technical solution of the utility model is achieved in that a kind of explosion proof control case malleation cooling device, it is characterized in that: comprise positive pressure controller, relief valve, cabinet cooler, Compressed Gas main entrance valve, three-way connection, cabinet cooler Compressed Gas inlet valve and control cubicle; Positive pressure controller is installed on the lower right side of control cubicle, and relief valve is installed on the upper left side of control cubicle; The cabinet cooler is installed on the control cubicle top, and the cabinet cooler is connected with cabinet cooler Compressed Gas inlet valve; Positive pressure controller, cabinet cooler Compressed Gas inlet valve, Compressed Gas main entrance valve are connected with three-way connection respectively.
Wherein, positive pressure controller and relief valve combination form complete positive pressure control system.
Wherein, the cabinet cooler is installed in the control cubicle top, forms parallel system with positive pressure controller.
The utility model compared with prior art has following beneficial effect:
1. field operation does not need to provide working power;
2. applicable to operation in the hot environment situation, and the fail safe that has improved field operation;
3. positive pressure controller and cabinet cooler small volume are simple in structure, are easy to install;
4. it is convenient to operate and control, and has improved simultaneously economy;
5. maintenance cost is low, is convenient to dismounting and replacing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The drawing explanation:
1, positive pressure controller, 2, relief valve, 3, the cabinet cooler, 4, Compressed Gas (air or inert gas) main entrance valve, 5, three-way connection, 6, cabinet cooler Compressed Gas (air or inert gas) inlet valve, 7, control cubicle.
Embodiment
Embodiment 1, with reference to Fig. 1, positive pressure controller 1 is installed on the lower right side of control cubicle 7, and relief valve 2 is installed on the upper left side of control cubicle 7; Cabinet cooler 3 is installed on control cubicle 7 tops, cabinet cooler 3 is connected with cabinet cooler Compressed Gas (air or inert gas) inlet valve 6 again; At last positive pressure controller 1, cabinet cooler Compressed Gas inlet valve 6, Compressed Gas (air or inert gas) main entrance valve 4 are connected with three-way connection 5 respectively, wherein positive pressure controller 1 makes up with relief valve 2, form complete positive pressure control system, cabinet cooler 3 forms parallel system with positive pressure controller 1; Positive pressure controller 1 need not working power, the inlet pressure of positive pressure controller 1 source of the gas of the ventilation volume of Automatic Detection and Control cabinet 7 and Real Time Monitoring; Cabinet cooler 3 need not working power, utilizes Compressed Gas (air or inert gas) for source of the gas imports control cubicle 7 inside with the cold air that distributes, and reduces and stable control cubicle 7 internal temperatures.
A kind of explosion proof control case malleation cooling device of the present utility model, during work, with Compressed Gas (air or inert gas) main entrance valve open, the malleation controller level is rotated to the service position, then positive pressure controller is realized the control cubicle automatic air-exchanging and is kept the pressure-fired function, if positive pressure controller detects entrance Compressed Gas (air or inert gas) pressure when being lower than the required minimum pressure of positive pressure controller, positive pressure controller warning device is with automatic triggering signal.When ambient temperature externally higher season, open cabinet cooler Compressed Gas inlet valve, then that the cold air that distributes is imported control cubicle is inner for the cabinet cooler, and hot gas is discharged; When ambient temperature externally low season, when not needing to reduce the control cubicle internal temperature, close cabinet cooler Compressed Gas inlet valve.
Above about specific descriptions of the present utility model, be not to be subject to the described technical scheme of the utility model embodiment for explanation the utility model only.Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacing utility model, to reach identical technique effect; As long as satisfy practical needs, all within protection range of the present utility model.
