Abstract
The utility model relates to the technical field of valve devices, in particular to a structure of a one-way valve. The structure of the one-way valve comprises a valve body and a valve core, wherein a valve channel is formed in the valve body; the valve core is arranged in the valve channel; the valve core comprises a spring, a ball body fixed at the upper end of the spring and a sealing ring which is concentrically arranged above the ball body with the ball body; the sealing ring is clamped in the valve channel; the lower end of the spring is fixed in the valve channel; and the inside diameter of the sealing ring is smaller than the diameter of the ball body. The structure of the one-way valve has the advantages of simpleness, low manufacturing cost and favorable non-return effect.
Description
Technical field
The utility model relates to the control valve unit technical field, particularly a kind of one-way valve structures.
Background technique
One-way valve is widely used in various device and the pipeline, by people are known.Existing one-way valve mainly is a falling formula one-way valve, generally constitute by valve body, valve seat and spool, because of structure be provided with unreasonable, existing one-way valve exists following deficiency and defective: 1, valve core structure complexity, manufacture difficulty is big, and cost is also higher, is unfavorable for wide popularization and application; 2, existing one-way valve is mainly born reverse pressure by the gravity of spool self, so under high-pressure situations, the non-return poor performance.So real being necessary of a kind of one-way valve simple in structure, that fabricating cost is low and the non-return performance is good of development.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of simple in structure, fabricating cost is low, the one-way valve structures that non-return is effective.
For achieving the above object, the utility model is by the following technical solutions:
A kind of one-way valve structures of the utility model, it comprises valve body and spool, and described valve body internal shaping has the valve road, and described spool is located in the valve road, and described spool comprises spring, is fixed in the spheroid of spring upper end and is arranged at the seal ring of spheroid top with the spheroid concentric; Described seal ring is arranged in the valve road, and described spring lower end is fixed in the valve road; The internal diameter of described seal ring is less than the diameter of spheroid.
Further, described spring and spheroid concentric are provided with.
Further, the contact position of described seal ring and spheroid is spherical shape.
The utility model beneficial effect is: a kind of one-way valve structures of the utility model, it comprises valve body and spool, described valve body internal shaping has the valve road, described spool is located in the valve road, described spool comprises spring, is fixed in the spheroid of spring upper end and is arranged at the seal ring of spheroid top with the spheroid concentric.When using the utility model, fluid flows through valve body from entering valve body internal valve road through the seal ring center, and when fluid returned, under the acting in conjunction of spring and fluid, spheroid engaged with seal ring, the cut-off valve road.The utility model is simple in structure, fabricating cost is low and non-return is effective.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Among the figure: 1, valve body, 2, the valve road, 3, spheroid, 4, spring, 5, seal ring
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, a kind of one-way valve structures of the utility model, it comprises valve body 1 and spool, the described valve body 1 general metallic material that adopts is made, its internal shaping has valve road 2, and described spool is located in the valve road 2, and valve road 2 each section shapes or big I are done different the setting according to the parts situation of spool, so that valve road 2 and spool coupling is provided with, accomplishes compact structure.
Described spool comprises spring 4, is fixed in the spheroid 3 of spring 4 upper ends and is arranged at the seal ring 5 of spheroid 3 tops with spheroid 3 concentrics; The same metallic material that adopts with existing valve body of described spring 4 and spheroid 3 is made, and seal ring 5 general employing compressive strength plastic material are preferably made.
Described seal ring 5 is arranged in the valve road 2, and described spring 4 lower ends are fixed in the valve road 2; Be fixed at spring 4 upper end spheroids 3 and spring 4 concentric settings, it is better flexible to be convenient to spring 4.Spheroid 3 tops and seal ring 5 form sealing state, and the internal diameter of seal ring 5 is convenient to seal ring 5 and spheroid 3 pressing form seals less than the diameter of spheroid 3.For reaching better sealing effect, described seal ring 5 is the spherical shape setting with the contact position of spheroid 3, thereby makes seal ring 5 and spheroid 3 form better sealing surface.
When using the utility model, fluid is from entering valve body 1 internal valve road 2, and through seal ring 5, under the acting in conjunction of spheroid 3 self gravitations and hydrodynamic pressure, spring 4 compresses, and spheroid 3 separates with seal ring 5, and fluid flows through valve body 1 internal valve road 2.When fluid returned, under the acting in conjunction of spring 4 elastic force and hydrodynamic pressure, spheroid 3 was fitted the cut-off valve road with seal ring 5.The utility model is simple in structure, fabricating cost is low and non-return is effective, long service life, and it is convenient to change.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
