Abstract
The utility model discloses a valve structure, which comprises the following components: a valve body, the valve body has oil inlet and an oil -out install the case in the valve body, the case is the linear sealing with the valve body, and install the spring in the case, the one end of spring is installed on the spring holder, and other end top is supported on the interior terminal surface of case, the front end of case is the arc structure, and the front end of case is processed has cylindrical groove the bottom processing in cylindrical groove has conical groove. The utility model discloses a processing has cylindrical groove on the preceding terminal surface of case to have conical groove in the processing of the bottom in cylindrical groove, fluid at first flows in the oil inlet, then in getting into cylindrical groove and conical groove, owing to the drainage effect of notch, has reduced the spray angle of fluid, and flow force has obtained the compensation.
Description
Technical field
This utility model relates to technical field of hydraulic pressure, particularly relates to a kind of valve mechanism.
Background technology
Hydraulic valve is the Automation Elements of a kind of pressure oil operation, and it is controlled by distributing valve pressure oil,
Generally it is applied in combination with electromagnetic distributing valve, can be used for distant control power station oil, gas and water pipeline system
The break-make of system.Be usually used in clamping, control, the oil circuit such as lubrication.Have direct acting type and type pilot point, many
Use type pilot.Hydraulic power have steady-state fluid force and instantaneous hydraulic dynamics point, under Steady Flow state,
When liquid flows through valve port, though flow velocity is constant, but flow in and out the momentum generation controlling volume of liquid
Change, this is spool to controlling caused by the active force of volume of liquid, and liquid effects is on spool
Counteracting force is exactly steady-state fluid force.
Utility model content
This utility model is in order to overcome deficiency of the prior art, it is provided that a kind of valve mechanism.
This utility model is to be achieved through the following technical solutions:
A kind of valve mechanism, including valve body, described valve body has oil-in and oil-out, at described valve
The internal spool that is provided with, described spool and valve body are linear sealing, and are provided with spring in described spool,
One end of described spring mounts elastically, other end contact on the inner face of spool, described valve
The front end of core is arcuate structure, and is machined with cylindrical groove in the front end of described spool, at described cylinder
The bottom of shape groove is machined with conical tank.
As optimal technical scheme of the present utility model, described valve body and spring base are machined with installing hole,
In installing hole, bolt is installed thus spring base is attached with valve body.
As optimal technical scheme of the present utility model, between described valve body and spring base, sealing is installed
Pad, and described sealing gasket is elastic sealing gasket.
As optimal technical scheme of the present utility model, the inwall of described oil-in is threaded,
It is threaded on the inwall of described oil-out.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by valve
It is machined with cylindrical groove on the front end face of core, and is machined with conical tank in the bottom of cylindrical groove, oil
First liquid flow in oil-in, subsequently in cylindrical groove and conical tank, due to drawing of notch
Stream effect, reduces the spray angle of fluid, and hydraulic power is compensated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched
The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of valve mechanism, including valve body 1, described valve body 1 has oil-in 2 and oil-out 3,
It is threaded on the inwall of described oil-in 2, the inwall of described oil-out 3 is threaded.
Being provided with spool 4 in described valve body 1, described spool 4 is linear sealing with valve body 1, and in institute
Being provided with spring 5 in stating spool 4, one end of described spring 5 is arranged on spring base 6, other end top
It is against on the inner face of spool 4, described valve body 1 and spring base 6 are machined with installing hole 9, installing
Hole 9 is provided with bolt 10 thus spring base 6 is attached with valve body 1, described valve body 1 and bullet
Sealing gasket 11 is installed between spring abutment 6, and described sealing gasket 11 is elastic sealing gasket.
The front end of described spool 4 is arcuate structure, and is machined with cylinder in the front end of described spool 4
Groove 7, is machined with conical tank 8 in the bottom of described cylindrical groove 7.By on the front end face of spool
Being machined with cylindrical groove 7, and be machined with conical tank 8 in the bottom of cylindrical groove 7, first fluid exist
Flowing in oil-in, subsequently in cylindrical groove 7 and conical tank 8, owing to the drain of notch is made
With, reducing the spray angle of fluid, hydraulic power is compensated.
Above are only preferred embodiment of the present utility model, not in order to limit this utility model,
All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle,
Within should be included in protection domain of the present utility model.
