Abstract
The invention discloses one-way valve of oil duct detection means, housing including upper end open, unidirectional valve housing is provided with housing, unidirectional valve housing includes cylinder, there is the groove of a matching check valve oil outlet end on cylinder, column body is provided with oil duct, oil duct one end communication groove bottom, the space that other end connection housing is surrounded, compression cylinder is provided with directly over groove, the piston rod of compression cylinder is connected with compact heap, the upper groove on compact heap with matching check valve oil inlet end, has the oil transportation channel communicated with upper groove on compact heap.Oil pressure when can be got through to check valve using the present invention is detected, the flow of check valve, oil pressure and flow value can be intuitively drawn using the oil pressure gauge display screen and flowmeter display screen on control cabinet under can detect oil pressure required for getting through check valve and specific a certain oil pressure using oil pressure gauge and flowmeter.
Description
Technical field
The present invention relates to check valve detection technique, and in particular to a oil duct for gallery pressure and flow detection is unidirectional
Valve detection device.
Background technology
Our company for critical value of the check valve when oil passes through i.e. check valve get through and specific a certain oil pressure under stream
The problem that amount is detected is researched and developed, and devises the present invention.
The content of the invention
The present invention is regarding to the issue above, there is provided one-way valve of oil duct detection means, when accurately can detect that check valve is got through
Oil pressure and specific a certain oil pressure under flow, simple structure is easily manufactured, and detection process is simple, quick.
In order to solve the above technical problems, one aspect of the present invention is：One-way valve of oil duct detection means, including
The housing of upper end open, is provided with unidirectional valve housing in housing, unidirectional valve housing includes cylinder, has a matching single on cylinder
To the groove of valve oil outlet end, column body is provided with oil duct, oil duct one end communication groove bottom, the sky that other end connection housing is surrounded
Between, compression cylinder is provided with directly over groove, the piston rod of compression cylinder is connected with compact heap, has matching unidirectional on compact heap
The upper groove of valve oil inlet end, has the oil transportation channel communicated with upper groove on compact heap.
Used as the preferred of such scheme, oil transportation channel is connected to fuel tank by oil pipe, and oil pipe is provided with oil pressure gauge and flow
Meter.
Used as the preferred of such scheme, oil pressure gauge and flowmeter connect control cabinet, have oil pressure gauge display screen on control cabinet
With flowmeter display screen and controlling switch.
The beneficial effects of the invention are as follows：Oil pressure when can be got through to check valve using the present invention is detected, using oil pressure
Table and flowmeter can detect the flow of check valve under oil pressure required for getting through check valve and specific a certain oil pressure, using control
Oil pressure gauge display screen and flowmeter display screen on case can intuitively draw oil pressure and flow value.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
With reference to embodiment, specific embodiment of the invention is further described.
As shown in figure 1, one-way valve of oil duct detection means, including upper end open housing 4, check valve installation is provided with housing
Seat 5, unidirectional valve housing includes cylinder, the groove 7 on cylinder with a matching check valve oil outlet end, and column body is provided with oil duct
6, oil duct one end communication groove bottom, the space that other end connection housing is surrounded is provided with compression cylinder 2 directly over groove, press
The piston rod 3 of tight cylinder is connected with compact heap 8, has the upper groove 9 of matching check valve oil inlet end on compact heap, has on compact heap
There is the oil transportation channel 10 communicated with upper groove.
Wherein, compression cylinder is fixed on support 1.
Oil transportation channel is connected to fuel tank by oil pipe, and oil pipe is provided with oil pressure gauge 11 and flowmeter 12.
Oil pressure gauge and flowmeter connection control cabinet, have oil pressure gauge display screen and flowmeter display screen and control on control cabinet
System switch.
When in use, first check valve is placed in groove, the piston rod of compression cylinder drives compact heap to compress check valve, makes
Between check valve and cylinder, compact heap formed sealing coordinate, in oil circuit oil through oil transportation channel enter check valve after certain
Pressure under open check valve again by oil duct flow out, can detect the oil pressure required for getting through check valve using oil pressure gauge and flowmeter
And under specific a certain oil pressure check valve flow, can be directly perceived using the oil pressure gauge display screen and flowmeter display screen on control cabinet
Draw oil pressure and flow value.
For a person skilled in the art, the technical scheme described in foregoing embodiments can still be repaiied
Change, or equivalent carried out to which part technical characteristic, it is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
