Abstract

The utility model discloses the steady pressure relief device of a kind of cubic hydraulic press high pressure, this device comprises booster and high-pressure oil passage, and high-pressure oil passage is also connected with hydraulic control one-way valve, Solenoid ball valve, choke valve and fuel tank; Connect hydraulic control one-way valve and Solenoid ball valve respectively from the high-pressure oil passage of booster bottom, Solenoid ball valve connects the oil circuit control of hydraulic control one-way valve, and hydraulic control one-way valve is connected with fuel tank by choke valve.This device can effectively control pressure release speed, and manufacturing cost is lower, and installation, maintenance is convenient.

Description

The steady pressure relief device of cubic hydraulic press high pressure
technical field:
The utility model relates to a kind of pressure relief device, is specifically related to the steady pressure relief device of a kind of cubic hydraulic press high pressure.
background technology:
On synthesizing cubic boron nitride cubic hydraulic press, pressure release mode and pressure release speed have direct relation to cubic hydraulic press top hammer service life, when using HP-HT synthesize cubic boron nitride, hard alloy top hammer is when extruding pyrophillite, and be subject to pyrophillite reaction force, stress is larger, if pressure release excessive velocities, stress discharges suddenly, there will be and splits hammer or venting big gun phenomenon, be easy to like this cause the injury to top hammer.At present, pressure release mode major part still adopts the pressure release of one-level pressure release mode, such pressure release speed is difficult to control, pressure release curve is not steady, there will be high pressure relief fast, the state that low pressure relief is slow, even arrive low pressure and often let out to go down phenomenon appearance, for this reason, some producers adopt increases little pump or relief valve, but does not fundamentally deal with problems.
utility model technology:
The purpose of this utility model is to solve cubic hydraulic press pressure release excessive velocities when pressure release, thus to the problem threatened of keeping the safety in production.
The technical scheme that the utility model adopts is: the steady pressure relief device of a kind of cubic hydraulic press high pressure, comprises booster and high-pressure oil passage, high-pressure oil passage is also connected with hydraulic control one-way valve, Solenoid ball valve, choke valve and fuel tank; Connect hydraulic control one-way valve and Solenoid ball valve respectively from the high-pressure oil passage of booster bottom, Solenoid ball valve connects the oil circuit control of hydraulic control one-way valve, and hydraulic control one-way valve is connected with fuel tank by choke valve.
The beneficial effect that the utility model produces is: by using this device, the pressure release speed of cubic hydraulic press obtains and effectively controls, pressure release curve is comparatively mild, do not occur again receiving low-pressure state from high voltage direct, even arrive low pressure and often let out to go down phenomenon, really effectively taken precautions against the generation of accident, solve pressure release problem up hill and dale, this device manufacturing cost is lower, also very convenient in mounting and adjusting and maintenance.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is pressure release curve comparison figure.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
The utility model is for the synthesis of on cubic hydraulic press used during cubic boron nitride, by increasing new device and then ensure that cubic hydraulic press is slow in high pressure relief, speeds control fast during low pressure relief on original oil circuit.
As shown in Figure 1, the steady pressure relief device of cubic hydraulic press high pressure comprises booster, high-pressure oil passage, hydraulic control one-way valve, Solenoid ball valve, choke valve and fuel tank.Wherein booster and high-pressure oil passage are the original parts of equipment, and when unloading high pressure by setting up new oil circuit equipment to ensure on high-pressure oil passage, pressure is stable.
Newly-increased oil circuit comprises the hydraulic control one-way valve and Solenoid ball valve that connect from high-pressure oil passage, Solenoid ball valve also connects the oil circuit control of hydraulic control one-way valve, for controlling the high-pressure leakage of hydraulic control one-way valve, hydraulic control one-way valve is connected with fuel tank by choke valve, the leakage rate of throttle valve control hydraulic oil.
As shown in Figure 2, by using this device, can obviously reach the object of unloading high pressure quick-release low pressure slowly, effectively controlling pressure release speed, protecting equipment and personal security, take precautions against the generation of accident.
The utility model is with low cost, installs, debugs conveniently, solve originally single relief mode.
