Abstract
The utility model relates to a quick pressure reducing circuit which comprises a hydraulic pump, a first pressure reducing valve, a second pressure reducing valve and a pressure gauge. The first pressure reducing valve, the second pressure reducing valve and the pressure gauge are respectively connected with the hydraulic pump, and the second pressure reducing valve is a pilot electromagnetic pressure reducing valve. The quick pressure reducing circuit has the advantages that the pressure on an outlet of each pressure reducing valve can be kept within a stable range, and the quick pressure reducing circuit is simple in structure, safe in operation and stable in work.
Description
Technical field
The utility model is specifically related to the fast decompression loop.
Background technique
Reduction valve is the outlet pressure that inlet pressure is reduced to a certain needs by regulating, and the energy of dependence medium itself, make outlet pressure automatically keep stable valve, from hydromechanical viewpoint, reduction valve is a throttle element that local resistance can change, by changing orifice size, the kinetic energy of flow velocity and fluid is changed, cause the different pressure losses, thereby reach the purpose of decompression, then rely on the adjusting of controlling with regulating system, fluctuation and the spring force of downstream pressure are balanced each other, make downstream pressure keep constant in certain margin of error, in hydraulic system, when force value that the needed working pressure of certain branch road is set lower than oil sources, can adopt the one-level pressure reducing circuit, existing pressure reducing circuit is due to job insecurity, the reduction valve outlet pressure is difficult to remain in a stable scope.
Summary of the invention
Technical problem to be solved in the utility model is to provide the fast decompression loop, and not only the reduction valve outlet pressure remains in a stable scope, and simple in structure, handling safety, working stability.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the fast decompression loop, comprise oil hydraulic pump, the first reduction valve be connected with oil hydraulic pump respectively, the second reduction valve, pressure gauge, and described the second reduction valve adopts type pilot electromagnetism reduction valve.
As preferably, described oil hydraulic pump is connected to the first fuel tank by the first reduction valve, described the second reduction valve is provided with the second fuel tank, this structured liquid press pump part fluid flow to the first fuel tank by the first reduction valve and is reduced pressure, oil hydraulic pump another part fluid is by the second reduction valve decompression, structure is more reasonable, easy to operate, quick.
As preferably, described oil hydraulic pump adopts unidirectional quantitative hydraulic pump, and this structured liquid press pump adopts unidirectional quantitative hydraulic pump, strengthen operation stability and Security.
As preferably, described pressure gauge one end is provided with the magnetic switch of pilot pressure table work, and the magnetic switch of this structural pressure table one end is controlled, and further improves operating security.
Beneficial effect:
The utility model adopts technique scheme that the fast decompression loop is provided, and not only the reduction valve outlet pressure remains in a stable scope, and simple in structure, handling safety, working stability.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the fast decompression loop, comprise oil hydraulic pump 1, the first reduction valve 2, the second reduction valve 3, the pressure gauge 4 that are connected with oil hydraulic pump 1 respectively, described the second reduction valve 3 adopts type pilot electromagnetism reduction valve, described oil hydraulic pump 1 is connected to the first fuel tank 7 by the first reduction valve 2, described the second reduction valve 3 is provided with the second fuel tank 5, and described oil hydraulic pump 1 adopts unidirectional quantitative hydraulic pump, and described pressure gauge 4 one ends are provided with the magnetic switch 6 of pilot pressure table 4 work.
During real work, the a part of fluid of this structured liquid press pump 1 flow to the first fuel tank 7 by the first reduction valve 2 and is reduced pressure, oil hydraulic pump 1 another part fluid is by the second reduction valve 3 decompressions, structure is more reasonable, easy to operate, quick, this structured liquid press pump 1 adopts unidirectional quantitative hydraulic pump, strengthen operation stability and Security, the magnetic switch 6 of this structural pressure table 4 end is controlled, further improve operating security, the utility model not only reduction valve outlet pressure remains in a stable scope, and simple in structure, handling safety, working stability.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
