Abstract
The utility model relates to a kind of corrosion-resistant hydrovalve, 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, spool is cone valve type, spool is inside, valve body contact end place is provided with the anticorrosive layer of cylindrical structural, the sealing surface of spool and valve body is arc shaped surface, is provided with the anti-corrosion block that sectional shape is semicircular structure between the anticorrosive layer outward edge on described spool and valve body contact end and spool outward edge.Anticorrosive layer and anti-corrosion block are set by the end face of the contact jaw at spool and valve body, spool can be protected can not to be damaged because of cavitation erosion, thus extend the working life of this one-way valve; By spool and valve body contact face are set to arc shaped surface, when this arc shaped surface can make spool that skew occurs when spool is subject to foreign impacts or spring generation lateral force, progressively excellent sealing can be recovered.
Description
Technical field
The utility model relates to hydrovalve technical field, particularly relates to a kind of corrosion-resistant hydrovalve.
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 hydraulically-controlled 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, such sealing means occurs because valve makes spool edge portions or the overall conical surface departing from valve body by the vibrations of slight all directions often, 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.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of corrosion-resistant hydrovalve.
The utility model is achieved through the following technical solutions:
A kind of corrosion-resistant hydrovalve, 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, described spool is inside, valve body contact end place is provided with the anticorrosive layer of cylindrical structural, the sealing surface of described spool and valve body is arc shaped surface, is provided with the anti-corrosion block that sectional shape is semicircular structure between the anticorrosive layer outward edge on described spool and valve body contact end and spool outward edge; Described anticorrosive layer is embedded in the inside of spool, and the left side of anticorrosive layer and spool left side coplanar; The thickness of described anticorrosive layer is 0.2-0.5mm; 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.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, by the end face of the contact jaw at spool and valve body, anticorrosive layer and anti-corrosion block are set, spool can be protected can not to be damaged because of cavitation erosion, thus to extend the working life of this one-way valve; By spool and valve body contact face are set to arc shaped surface, when this arc shaped surface can make spool that skew occurs when spool is subject to foreign impacts or spring generation lateral force, progressively excellent sealing can be recovered.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve body; 2. spool; 3. spring; 4. anticorrosive layer; 5. arc shaped surface; 6. anti-corrosion block; 7. back-up ring; 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.
The corrosion-resistant hydrovalve of described one, comprise the valve body 1 with the internal fluid channels along its Axis Extension determined, be arranged on the spool 2 in valve body 1, for the spring 3 of contact spool 2 in spool 2, and spacing back-up ring 7 is carried out to spring 3, described spool 2 is cone valve type, described spool 2 is inside, valve body 1 contact jaw place is provided with the anticorrosive layer 4 of cylindrical structural, described spool 2 is arc shaped surface 5 with the sealing surface of valve body 1, the anti-corrosion block 6 that sectional shape is semicircular structure is provided with between anticorrosive layer 4 outward edge on described spool 2 and valve body 1 contact jaw and spool 2 outward edge.
Described anticorrosive layer 4 is embedded in the inside of spool 2, and the left side of anticorrosive layer 4 and spool 2 left side coplanar.Anticorrosive layer and anti-corrosion block are set by the end face of the contact jaw at spool and valve body, spool can be protected can not to be damaged because of cavitation erosion, thus extend the working life of this one-way valve; By spool and valve body contact face are set to arc shaped surface, when this arc shaped surface can make spool that skew occurs when spool is subject to foreign impacts or spring generation lateral force, progressively excellent sealing can be recovered.
In the present embodiment: the thickness of described anticorrosive layer 4 is 0.2-0.5mm, and the side of described valve body 1 offers liquid entering hole 8, and opposite side offers liquid outlet 9, and described liquid entering hole 8 and liquid outlet 9 are screw mouth.
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.
