Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of one-way valve, is used for strengthening unidirectional Operating stability of valve.
Below by specific embodiment the technical solution of the utility model is described in detail, sees also Fig. 1 to Fig. 2:
A kind of one-way valve comprises: locating cover 10, loam cake 20, spring 30 and be used for entangling the spring housing 40 of spring 30; Locating cover 10 passes loam cake 20 spring housing 40 is connected with loam cake 20.
See also Fig. 1 or Fig. 2, Fig. 1 is the explosive view of one-way valve, and Fig. 2 is the partial sectional view of one-way valve.Spring housing 40 can entangle spring 30, and spring housing 40 can firmly be connected by locating cover 10 with loam cake 20.Wherein, locating cover 10 can pass loam cake 20 spring housing 40 is pressed on the loam cake 20, so that spring housing 40 can be connected fastening with loam cake 20.
Wherein, can consult Fig. 1 and Fig. 2, an end of locating cover 10 can pass loam cake 20 from the below of loam cake 20, and spring housing 40 is pressed to loam cake 20, and the other end of locating cover 10 is stuck in the below of loam cake 20.Locating cover 10 in the present embodiment utilizes mechanics angle principle, stressed being stuck in the loam cake 20, and spring housing 40 is pressed to loam cake 20, so that spring housing 40 firmly is connected with loam cake 20, bearing capacity is stronger, and spring housing 40 can be fixed on the loam cake 20.
Concrete, for so that locating cover 10 can better be pressed to loam cake 20 with spring housing 40, can be provided with the first boss 101 at locating cover 10, when one-way valve assembles, the end that locating cover 10 is provided with the first boss 101 can pass loam cake 20 from the below of loam cake 20, the first boss 101 can be pressed to loam cake 20 with spring housing 40, and the other end of locating cover 10 is stuck in the below of loam cake 20.The first boss 101 on the locating cover 10 and spring housing 40 are connected with loam cake and firmly are connected.
Optionally, can consult Fig. 1 or Fig. 2, the one-way valve of present embodiment can also comprise spring capping 50, and this spring capping 50 can be used for fixing spring 30.Optionally, for better retaining spring 30, can be provided with the second boss 501 towards the direction of spring 30 at spring capping 50.
Optionally, when locating cover 10 passed loam cake 20 spring housing 40 is pressed to loam cake 20, the first boss 101 on the loam cake 20 can withstand spring capping 50.
The assembly process of present embodiment is: at first spring capping 50, spring 30 and spring housing 40 are assembled together, then spring housing 40 is passed loam cake 20 from the bottom of loam cake 20, at this moment, spring housing 40 is connected with loam cake 20, but can not be fixedly connected with, adopt locating cover 10 in the present embodiment, 20 direction is passed loam cake 20 from spring capping 50 to loam cake, utilize the first boss 101 that spring housing 40 is pressed to loam cake 20, so that one-way valve composition from outside to inside is followed successively by: loam cake 20, spring housing 40 and locating cover 10.
