Abstract
The utility model belongs to hydraulic pressure control valve technical field, and in particular to a kind of structure of relief valve, including valve body, valve body is interior to be equipped with cone valve and conical valve base, and for conical valve base with the oil inlet of valve body using being threadedly coupled, conical valve base is equipped with the throttle orifice passed through for oil liquid；Pass through in throttle orifice without oil liquid or when oil liquid pressure deficiency, under the action of the spring, cone valve matches carry out oil sealing with throttle orifice.The utility model is compact-sized, convenient to install and maintain, using the conical valve base for having throttle orifice, avoids cone valve directly with the direct cooperation of valve body, the mating surface effectively prevented on valve body is damaged, and maintenance cost is reduced.
Description
Technical field
The utility model belongs to hydraulic pressure control valve technical field, and in particular to a kind of structure of relief valve.
Background technique
Overflow valve is a kind of pressure-control valve, and level pressure overflow, pressure stabilizing, system unloaded and safety are mainly played in hydraulic device
Protective effect.The cone valve of existing pilot operated compound relief valve directly cooperates with valve body, if the mating surface on valve body is damaged, needs
Replace entire pilot operated compound relief valve, it has not been convenient to repair, while increase maintenance cost.
Summary of the invention
Place, the utility model provide a kind of structure of relief valve in order to overcome the above-mentioned deficiencies of the prior art.
The utility model is achieved by the following technical solution: a kind of structure of relief valve, including valve body, is equipped in valve body
Cone valve and conical valve base, for conical valve base with the oil inlet of valve body using being threadedly coupled, conical valve base is equipped with the throttle orifice passed through for oil liquid；
Pass through in throttle orifice without oil liquid or when oil liquid pressure deficiency, under the action of the spring, cone valve matches carry out oil sealing with throttle orifice.
Further, the spring is placed in the blind hole of adjustment seat, and adjustment seat is used with valve body and is threadedly coupled.
Further, when playing the role of oil sealing, the cone valve and throttle orifice are face contact.
The beneficial effects of the utility model are: the application is compact-sized, and it is convenient to install and maintain, using the cone for having throttle orifice
Valve seat avoids cone valve directly with the direct cooperation of valve body, and the mating surface effectively prevented on valve body is damaged, reduced
Maintenance cost, while the throttle orifice on conical valve base is filtered the pressure fluctuation of high pressure oil, eliminates pressure oscillation when overflow
And noise.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the conical valve base structural schematic diagram of the utility model；
In figure, 1, sealing ring, 2, adjustment seat, 2-1, blind hole, 3, spring, 4, cone valve, 5, conical valve base, 5-1, throttle orifice, 6,
Valve body.
Specific embodiment
Below according to drawings and examples, the present invention will be further described.
As depicted in figs. 1 and 2, a kind of structure of relief valve, including valve body 6, valve body 6 is interior to be equipped with cone valve 4, conical valve base 5, spring
3 and adjustment seat 2, conical valve base 5 is with the oil inlet of valve body 6 using being threadedly coupled, and conical valve base 5 is equipped with the throttle orifice passed through for oil liquid
5-1；The spring 3 is placed in the blind hole 2-1 of adjustment seat 2, and adjustment seat 2, using being threadedly coupled, is adjusted with valve body 6 by changing
The screw-in depth of section seat 2 carrys out the pretightning force of adjustment spring 3, thus the pressure threshold of regulation relief valve, between adjustment seat 2 and valve body 6
Equipped with sealing ring 1.Pass through in throttle orifice 5-1 without oil liquid or when oil liquid pressure deficiency, under the action of spring 3, cone valve 4 and throttling
Hole 5-1 matches carry out oil sealing.When overflow valve works, by P mouthfuls of oil inlets, T mouthfuls fuel-displaced, and when overflow valve is opened, oil liquid is first passed through
The throttle orifice 5-1 of 5 front end of conical valve base, throttle orifice 5-1 are filtered the pressure fluctuation of high pressure oil, eliminate pressure wave when overflow
Dynamic and noise.
As the improvement of the present embodiment, the face that conical valve base 5 is matched with cone valve 4 uses the conical surface, when playing the role of oil sealing,
The cone valve 4 and throttle orifice 5-1 is face contact, and the line compared to right angle point side formula conical valve base contacts, the oil sealing effect of face contact
It is more superior.
The utility model is compact-sized, and installation and maintenance are more convenient, using the conical valve base for having throttle orifice, avoids cone valve
Directly with the direct cooperation of valve body, the mating surface effectively prevented on valve body is damaged, and is reduced maintenance cost, is bored simultaneously
Throttle orifice on valve seat is filtered the pressure fluctuation of high pressure oil, eliminates pressure oscillation when overflow and noise.
