Abstract
The utility model provides a pressure accumulator valve plate is suppressed and is tried out leaks frock, includes oil pump, first three-way pipe, test pressure accumulator and can with valve plate pressure accumulator mount pad complex sealed lid, the first interface connection of the end of producing oil of oil pump through check valve and first three-way pipe, the second interface connection of test pressure accumulator through first oil pipe and first three-way pipe, sealed covering is equipped with the oiling joint, the third interface connection of oiling joint through second oil pipe and first three-way pipe. The test accumulator that the leak test frock was used can simulate the actual frock environment of valve plate, under the assistance of leak test frock, can be effectively quick completion valve plate leak test.
Description
Technical Field
The utility model relates to a test tool, in particular to a pressure accumulator valve plate pressing leakage test tool.
Background
In the maintenance project of gearbox accumulator valve plate, one of them is to suppress the leak test to the valve plate, and the test process is squeezed into certain oil pressure to the accumulator mount pad on the valve plate earlier, then observes whether the mount pad appears the seepage on the valve plate and judges the quality of valve plate again. At present, no professional tool is used for pressing and leakage testing of the valve plate, so that the test operation efficiency is low.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a pressure accumulator valve plate pressing leakage test tool which can improve the efficiency of test operation.
In order to solve the technical problems, the technical scheme of the utility model is as follows: the utility model provides a pressure accumulator valve plate is suppressed and is tried out leaks frock, includes oil pump, first three-way pipe, test pressure accumulator and can with valve plate pressure accumulator mount pad complex sealed lid, the first interface connection of the end of producing oil of oil pump through check valve and first three-way pipe, the second interface connection of test pressure accumulator through first oil pipe and first three-way pipe, sealed covering is equipped with the oiling joint, the third interface connection of oiling joint through second oil pipe and first three-way pipe. The principle of the utility model is as follows: firstly, assembling a sealing cover and a pressure accumulator mounting seat of a valve plate to be tested, and ensuring that the pressure accumulator mounting seat is in a closed state; the oil pump is started to pump oil into the test pressure accumulator, the test pressure accumulator is connected with the sealing cover through the first three-way pipe, so that the actual working environment of the valve plate can be simulated, the test pressure accumulator can buffer the impact of oil pressure on the valve plate, and the oil is buffered and released by the pressure accumulator and then is conveyed to the sealing cover through the second oil pipe; and finally, the oil enters the valve plate through the oil injection joint on the sealing cover, and the leakage condition of the valve plate is tested in a pressurization environment.
As an improvement, the oil pump is arranged in the oil groove, and the oil inlet end of the oil pump is communicated with the oil groove.
As an improvement, the one-way valve is connected with a first connector of the second three-way pipe, a second connector of the second three-way pipe is connected with a first connector of the first three-way pipe, and a third connector of the second three-way pipe is connected with the oil discharge pipe through a first manual valve.
As an improvement, the check valve is respectively connected with the oil pressure gauge and the second three-way pipe through a third three-way pipe.
As an improvement, a third connector of the first three-way pipe is connected with a second oil pipe through a second manual valve.
Compared with the prior art, the utility model has the following beneficial effects:
the test accumulator that the leak test frock was used can simulate the actual frock environment of valve plate, under the assistance of leak test frock, can be effectively quick completion valve plate leak test.
Drawings
FIG. 1 is a schematic view of the present invention.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in figure 1, the pressure accumulator valve plate pressing and leakage testing tool comprises an oil pump 4, a first three-way pipe 7, a test pressure accumulator 12 and a sealing cover 14 capable of being matched with a pressure accumulator mounting seat of a valve plate. The oil pump 4 and the test pressure accumulator 12 are fixed on the fixing plate 1 to form an integral structure, a tool needs to be placed in an oil tank during testing, and the oil inlet end 3 of the oil pump 4 is communicated with the oil tank and can directly suck oil in the oil tank; the oil outlet end of the oil pump 4 is connected with a one-way valve 11, the one-way valve 11 is respectively connected with an oil pressure gauge 8 and a first connector of a second three-way pipe 5 through a third three-way pipe 9, a second connector of the second three-way pipe 5 is connected with a first connector of a first three-way pipe 7, a third connector of the second three-way pipe 5 is connected with the oil discharge pipe 2 through a first manual valve 6, after the test is finished, the first manual valve 6 is opened, and oil in the tool and the valve plate flows back to the oil groove through the oil discharge pipe 2; the test pressure accumulator 12 is connected with a second interface of the first three-way pipe 7 through a first oil pipe 10, an oil injection joint 15 is arranged on the sealing cover 14, the oil injection joint 15 is connected with a third interface of the first three-way pipe 7 through a second oil pipe 13, and the second interface and the third interface of the first three-way pipe 7 are coaxial; and a third interface of the first three-way pipe 7 is connected with a second oil pipe 13 through a second manual valve.
The principle of the utility model is as follows: firstly, assembling the sealing cover 14 and a pressure accumulator mounting seat of a valve plate to be tested, and ensuring that the pressure accumulator mounting seat is in a closed state; the oil pump 4 is started to pump oil into the test pressure accumulator 12, the test pressure accumulator 12 is connected with the sealing cover 14 through the first three-way pipe 7, so that the actual working environment of the valve plate can be simulated, the test pressure accumulator 12 can buffer the impact of oil pressure on the valve plate, and the oil is buffered and released by the pressure accumulator and then is conveyed to the sealing cover 14 through the second oil pipe; finally, the oil enters the valve plate through the oil injection joint on the sealing cover 14, and the leakage condition of the valve plate is tested in a pressurization environment.
