Description
Technical Field
The invention relates to a controllable high-pressure oil way distribution module, and belongs to the technical field of hydraulic boosting tools.
Background
In the installation process of a pressure container cover in a nuclear power plant, bolts need to be pre-tightened, in the process of pre-tightening the bolts by using a small single bolt stretcher, a plurality of single machines are generally used for working together, but only one pump for power output is needed, and therefore an oil way distribution module needs to be used.
The originally used oil circuit distribution module only has the function of oil separation, one oil circuit inlet and a plurality of oil circuit outlets, the outlets simultaneously discharge oil, the hydraulic oil flow and the oil pressure of each outlet in the working process are the same and can not be adjusted, and the quick connector can not be independently turned off, and if a certain oil circuit outlet is not needed, the corresponding quick connector can only be pulled out.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention develops a controllable high-pressure oil way distribution module, which can adjust the switch of an outlet of one oil way at any time, when one stretcher works completely in the working process, the pressure does not need to be boosted, a quick connector does not need to be detached, and only a shutoff valve needs to be screwed to a closed position. The control is more flexible, and the working efficiency and the working accuracy are improved. The technical scheme of the invention is as follows: a controllable high-pressure oil way distribution module comprises a module shell, wherein the module shell is of an integrally formed structure comprising a shell, a closing valve and an oil way channel, one side of the module shell is connected with a male connector, and the other side of the module shell is connected with a female connector; the inside of the shut-off valve is provided with a jackscrew A, a steel ball A, a spring, a steel ball B, a filling cylinder, a steel ball D and a plug which are sequentially in contact connection, one side of the module shell is provided with the jackscrew B, the jackscrew B is connected with an oil passage through the steel ball C, and the number of the shut-off valves is 3.
Furthermore, the diameter of the steel ball A is 7 mm.
Furthermore, the diameters of the steel ball B, the steel ball C and the steel ball D are 4 mm.
Further, the jackscrew A and the jackscrew B are M8 jackscrews.
The invention has the following beneficial effects: the invention does not install the valve handle relative to the control rod part of the shutoff valve, and is matched with a detachable valve handle for alternate use, thereby ensuring the complete function of the distribution module and the minimum size of the whole module. The principle of the one-way valve is adopted in the shut-off valve, so that the stability of an oil way during shut-off is ensured, the valve core is sealed more tightly, and the possibility of oil pressure leakage is greatly reduced.

Wherein: 1. the device comprises a male connector, 2, a module shell, 3, a female connector, 4, jackscrews B, 5, steel balls C, 6, jackscrews A, 7, steel balls A, 8, springs, 9, steel balls B, 10, a filling cylinder, 11, a plug, 12 and a steel ball D.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1-4, a controllable high-pressure oil path distribution module comprises a module housing 2, wherein the module housing 2 is an integrally formed structure comprising a shell, a closing valve and an oil path channel, one side of the module housing 2 is connected with a male connector 1, and the other side is connected with a female connector 3; the inside of the shut-off valve is provided with a jackscrew A6, a steel ball A7, a spring 8, a steel ball B9, a filling cylinder 10, a steel ball D12 and a plug 11 which are sequentially in contact connection, one side of the module shell 2 is provided with the jackscrew B4, and the jackscrew B4 is connected with an oil passage through a steel ball C5. The number of the shut-off valves is 3. The diameter of the steel ball A7 is 7 mm. The diameters of the steel ball B9, the steel ball C5 and the steel ball D12 are 4 mm. The jackscrew A6 and the jackscrew B4 are M8 jackscrews.
On the premise of ensuring the function of the oil path distribution module, the invention can arbitrarily cut off one oil path outlet without influencing the oil path functions of other connected inlets and outlets. And the interface of the shut-off valve can bear 150MPa high pressure without leakage, the material of the oil way distribution module is analyzed and optimized, and the smaller the weight is, the better the module can work normally.
The using process of the invention is as follows: hydraulic oil is fed through the male connector 1 through the passage. When the plug 11 is screwed down, the plug 11 props against the steel ball D12, the steel ball D12 props against the filling cylinder 10, and the filling cylinder 10 props against the steel ball B9 and the oil path of the spring 8 and enters the equipment after passing through the female joint 3. The jackscrew A6 is screwed down, the steel ball A7 abuts against the spring 8, the spring 8 bounces the steel ball B9, and the steel ball B9 forms a line seal with the module shell 2 filling the peripheral part of the cylinder 10 to realize the oil circuit shutoff.
The foregoing examples are provided for illustration and description of the invention only and are not intended to limit the invention to the scope of the described examples. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many variations and modifications may be made in accordance with the teachings of the present invention, which variations and modifications are within the scope of the present invention as claimed.
