Description
Technical field
The utility model relates to hydrovalve field, particularly relates to a kind of one-way valve.
Background technique
Hydrovalve is the Automation Elements of a kind of pressure oil operation, and it is by the control of voltage distribution valve pressure oil, and usual and electromagnetic distributing valve combinationally uses, and can be used for the break-make of distant control water power plant oil, gas, water piping system; It is the element being used for controlling liquid body pressure power ﹑ flow and direction in hydraulic transmission, wherein pilot pressure be called pressure valve, what control flow is called flow control valve, control system lead to ﹑ break and flow to be called position control valve.One-way valve is mainly used to control liquid stream one way flow in hydraulic system, and conventional one-way valve is divided into common one-way valve and Pilot operated check valve two class.The effect of common one-way valve in hydraulic system only allows liquid stream to pass through along pipeline direction, and the flowing in another direction is then cut off, and according to the difference of runner, common one-way valve has straight-through type and right-angle type two kinds of typical structures.Straight check valve liquid flow inlet and outlet runner communicate, therefore be generally tubular type and install and connect (being connected in system by the Taper Pipe at valve body two ends or straight pipe thread hole and pipe joint).The spool of straight check valve has ball-valve type and cone valve type two kinds of forms.
In the production of one-way valve with in using, sealing part is insoluble technical problem always.Existing low-pressure hydraulic check valve, valve body upper oil hole is the conical surface, and the edge of the circular seal face of spool is rigidity point limit, and the spring being positioned at the spool back side promotes spool travel, makes sharp limit and the valve body taper-face contact of seal spool end face, forms line face rigid seal.In use, often occur because valve makes spool edge portions or the overall conical surface departing from valve body by the vibrations of slight all directions, form valve opening state, cause hydraulic system entanglement, simultaneously due to spool after a long time use, spool and valve body contact end can be damaged because of cavitating, thus cause the damage of valve.For the problems referred to above, a kind of technological scheme of solution is now proposed.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of one-way valve, by adopting linear sealing, improves its sealing effect.
The utility model is achieved through the following technical solutions:
A kind of one-way valve, to comprise in the valve body with the internal fluid channels along its Axis Extension determined, the spool be arranged in valve body, spool for the spring of contact spool and spacing back-up ring is carried out to spring, described spool is cone valve type, the front-end face of described spool is provided with arc bump, described arc bump adopts corrosion resistant alloy material to make, and the hardness of described arc bump is higher than the hardness of valve body; Described spool center outer surface is evenly provided with multiple guide pad, and described guide pad contacts with the guiding groove be arranged on valve interior surface.
As optimal technical scheme of the present utility model, the side of described valve body offers liquid entering hole, and opposite side offers liquid outlet, and described liquid entering hole and liquid outlet are screw mouth.
As optimal technical scheme of the present utility model, the two ends of described guiding groove, guide pad are equipped with fillet.
As optimal technical scheme of the present utility model, the number of described guide pad is two.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, by being provided with arc bump on spool, spool can being protected can not to be damaged because of cavitation erosion, thus extend the working life of this one-way valve; By arranging guide pad and guiding groove on spool and valve body, when spool be subject to external fluid medium all directions impact after or spring generation lateral force, guide pad and guiding groove can ensure that spool and valve body ensure better to seal all the time and contact, and improve its sealing effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve body; 2. spool; 3. spring; 4. back-up ring; 5. guiding groove; 6. guide pad; 7. arc bump; 8. liquid entering hole; 9. liquid outlet.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of one-way valve, to comprise in the valve body 1 with the internal fluid channels along its Axis Extension determined, the spool 2 be arranged in valve body 1, spool 2 for the spring 3 of contact spool 2 and spacing back-up ring 4 is carried out to spring 3, described spool 2 is cone valve type, the front-end face of described spool 2 is provided with arc bump 7, described arc bump 7 adopts corrosion resistant alloy material to make, and the hardness of described arc bump 7 is higher than the hardness of valve body 1; Described spool 2 center outer surface is evenly provided with multiple guide pad 6, described guide pad 6 contacts with the guiding groove 5 be arranged on valve body 1 internal surface, the two ends of described guiding groove 5, guide pad 6 are equipped with fillet, the side of described valve body 1 offers liquid entering hole 8, opposite side offers liquid outlet 9, and described liquid entering hole 8 and liquid outlet 9 are screw mouth.By being provided with arc bump on spool, spool can being protected can not to be damaged because of cavitation erosion, thus to extend the working life of this one-way valve; By arranging guide pad and guiding groove on spool and valve body, when spool be subject to external fluid medium all directions impact after or spring generation lateral force, guide pad and guiding groove can ensure that spool and valve body ensure better to seal all the time and contact, and improve its sealing effect.
In the present embodiment: the number of described guide pad 6 is two.
When liquid stream flows into from liquid entering hole 8 direction, the hydraulic coupling of oil suction chamber overcomes to act on spool goes out hydraulic coupling, the active force of spring, the surface friction drag between spool and valve body that oil pocket produces, back down spool, fluid flows to liquid outlet 9 from liquid entering hole 8, realizes forward flow.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
