Abstract
The utility model relates to a novel hydraulic pressure unilateral control valve, including valve body, disk seat, oil circuit through -hole, case, spring, one serve and be equipped with the conical surface with the case contacts on the disk seat, even anticorrosion material layer on the cone point surface of case, the inside center of case is equipped with the cavity, be equipped with at least one free motion's balanced ball in the cavity. The utility model relates to a rationally, through setting up the conical surface on the disk seat, can make the disk seat and the cone point of case contact for the face to the wearing and tearing that have alleviateed the case have improved the life of valve, through setting up the anticorrosion material layer at case cone point surface, can effectively protect the case can not take place because of the cavitation erosion to damage, through at inside cavity and the balanced ball of setting up of case, when the case took place certain laterally offset, the dynamic adjustment of case can be realized to the balance ball to make the case progressively reach the balance.
Description
Technical field
The utility model relates to a kind of novel hydraulic one-way control valve, particularly relates to a kind of novel hydraulic one-way control 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.
The essential structure of existing high-pressure hydraulic one-way valve is: in valve body, one end is provided with the valve seat of band oil circuit through hole, and middle part is can along the taper valve core of valve interior wall axial displacement, and the back side of spool directly connects Returnning spring.The blocking-up of oil circuit is the promotion relying on taper valve core back side spring, makes spool to the displacement of valve seat direction, the oil circuit aperture central authorities on the cone point automatic centering valve seat in spool front, and by its shutoff.A shutoff face Line Contacts between the spool of the high-pressure hydraulic one-way valve of this structure and valve seat, easy like this wearing and tearing are caused to spool conical surface, valve operationally also can cause damage to spool because of cavitation erosion simultaneously, make spool shutoff not tight, time serious, obtain replacing valve, the impact of high-pressure hydraulic one-way valve to spool is larger simultaneously, and when spring has lateral force will cause the skew of spool, therefore just need to carry out Balance Treatment to spool.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 novel hydraulic one-way control valve.
The utility model is achieved through the following technical solutions:
A kind of novel hydraulic one-way control valve, comprise valve body, described valve body one end is provided with valve seat, described valve seat inside is provided with oil circuit through hole, and described valve seat one end contacts with spool, and the described spool the other end and spring interface touch, one end that described valve seat contacts with spool is provided with the conical surface, even anticorrosive layer on the cone point outer surface of described spool, the inside center of described spool is provided with cavity, is provided with at least one free-moving balanced ball in described cavity; The angle of inclination of the described conical surface is identical with the angle of inclination of the cone point of spool; Described anticorrosive layer is fixedly connected with spool cone point outer surface.
Compared with prior art, the beneficial effects of the utility model are: the utility model is reasonable in design, by valve seat arranges the conical surface, valve seat and the cone point of spool can be made to be that face contacts, thus alleviate the wearing and tearing of spool, improve the working life of valve; By arranging anticorrosive layer at spool cone point outer surface, can not be damaged because of cavitation erosion by available protecting spool; By arranging cavity and balanced ball at valve core inside, when certain laterally offset occurs spool, balanced ball can realize the dynamic adjustments of spool, thus makes spool progressively reach balance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve body; 2. valve seat; 3. oil circuit through hole; 4. spool; 5. spring; 6. the conical surface; 7. anticorrosive layer; 8. cavity; 9. balanced ball.
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 novel hydraulic one-way control valve, comprise valve body 1, described valve body 1 one end is provided with valve seat 2, described valve seat 2 inside is provided with oil circuit through hole 3, and described valve seat 2 one end contacts with spool 4, and described spool 4 the other end contacts with spring 5, one end that described valve seat 2 contacts with spool 4 is provided with the conical surface 6, the conical surface 6 can make valve seat 2 and the cone point of spool 4 be that face contacts, thus alleviates the wearing and tearing of spool 4, improves the working life of valve.On the cone point outer surface of described spool 4, even anticorrosive layer 7, can not be damaged because of cavitation erosion by available protecting spool 4.The inside center of described spool 4 is provided with cavity 8, and be provided with at least one free-moving balanced ball 9 in described cavity 8, when certain laterally offset occurs spool 4, balanced ball 9 can realize the dynamic adjustments of spool 4, thus makes spool 4 progressively reach balance.The angle of inclination of the described conical surface 6 is identical with the angle of inclination of the cone point of spool 4, and described anticorrosive layer 7 is fixedly connected with spool 4 cone point outer surface, and described cavity 8 is rectangular configuration cavity or round structure cavity.By valve seat arranges the conical surface, valve seat and the cone point of spool can be made to be that face contacts, thus to alleviate the wearing and tearing of spool, improve the working life of valve; By arranging anticorrosive layer at spool cone point outer surface, can not be damaged because of cavitation erosion by available protecting spool; By arranging cavity and balanced ball at valve core inside, when certain laterally offset occurs spool, balanced ball can realize the dynamic adjustments of spool, thus makes spool progressively reach balance.
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.
