Abstract
The utility model relates to a pressure relief system of a cubic hydraulic pressure machine. The pressure relief system comprises an ultrahigh-pressure working cylinder, a two-position two-way valve, a primary pressure relief valve, a pressure-relief proportioning valve and an oil tank, wherein the ultrahigh-pressure working cylinder, the two-position two-way valve, the primary pressure relief valve and the oil tank are sequentially connected with one another by a pipeline, one end of the pressure-relief proportioning valve is connected between the two-position two-way valve and the primary pressure relief valve by a pipeline, and the other end of the pressure-relief proportioning valve is connected to the oil tank by a pipeline. The pressure relief system of the cubic hydraulic pressure machine is additionally provided with the pressure-relief proportioning valve, so that the pressure relief speed can be controlled, the pressure relief stability is improved, the sealing property of pyrophyllite is improved, the shooting probability is reduced, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of composition system of cubic hydraulic press, is specifically related to a kind of depressurized system of cubic hydraulic press, belongs to diamond synthesis device technical field.
Background technology
After diamond has synthesized in high temperature and high pressure environment, pressure need to be let out, the de-stabilising effect of release speed arrives the pyrophillite coefficient of expansion after compression, causes pyrophillite sealing effectiveness poor, causes release venting big gun, has increased production cost.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of depressurized system with structure improved cubic hydraulic press, to overcome described defect of the prior art.
Utility model content
For addressing the above problem, it is a kind of simple in structure that the purpose of this utility model is to provide, the depressurized system of the stable and cubic hydraulic press that release speed is controlled of release.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of depressurized system of cubic hydraulic press, and it comprises super-pressure working cylinder, two position two-way valve, one-level pressure-relief valve, release proportioning valve and fuel tank; Wherein, described super-pressure working cylinder, two position two-way valve, one-level pressure-relief valve are connected by pipeline successively with fuel tank; Described release proportioning valve one end is connected between two position two-way valve and one-level pressure-relief valve by pipeline, and the other end is connected to fuel tank by pipeline.
The depressurized system of cubic hydraulic press of the present utility model is further set to: described one-level pressure-relief valve is all the time in conducting state.
Compared with prior art, the utlity model has following beneficial effect: the depressurized system of cubic hydraulic press of the present utility model is by setting up release proportioning valve, the speed of release can be controlled, release stability improves, strengthened the sealing of pyrophillite, reduce the probability of blowing out, saved production cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the depressurized system of cubic hydraulic press of the present utility model.
The specific embodiment
Refer to shown in Figure of description 1, the depressurized system that the utility model is a kind of cubic hydraulic press, it is comprised of several parts such as super-pressure working cylinder 1, two position two-way valve 3, one-level pressure-relief valve 4, release proportioning valve 6 and fuel tanks 5.
Wherein, described super-pressure working cylinder 1, two position two-way valve 3, one-level pressure-relief valve 4 and fuel tank 5 are connected successively by pipeline 2.Described two position two-way valve 3 when release in conducting state, when super-pressure working cylinder 1 work in closure state.Described one-level pressure-relief valve 4 is all the time in conducting state.
Described release proportioning valve 6 one end are connected between two position two-way valve 3 and one-level pressure-relief valve 4 by pipeline 2, and the other end is connected to fuel tank 5 by pipeline 2.This release proportioning valve 6 is in stress-relief process, and flow that can regulator solution force feed, controls release speed.
The depressurized system of cubic hydraulic press of the present utility model, by setting up release proportioning valve 6, the speed of release can be controlled, and release stability improves, and has strengthened the sealing of pyrophillite, has reduced the probability of blowing out, and has saved production cost.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
