Referring to fig. 1 to 4, the present embodiment provides a novel leakage-stopping one-way valve structure 100, which includes a one-way valve water inlet casing 110, a one-way valve water outlet casing 120, a sealing ring 130, a sealing rubber head 140 and a spring 150. The one-way valve water inlet shell 110 is made of plastic material, has elasticity, and is recessed inwards to form an annular one-way valve water inlet shell support body 111. The one-way valve outlet casing 120 is made of plastic material, has elasticity, and is recessed inwards to form an annular one-way valve outlet casing support body 121. The one-way valve water outlet shell 120 is sleeved in the one-way valve water inlet shell 110, the sealing ring 130 is arranged between the annular one-way valve water inlet shell supporting body 111 and the one-way valve water outlet shell 120, and a sealed cavity is formed by the three components. The sealing rubber head 140 and the spring 150 are arranged in the sealing cavity, and extend from the annular one-way valve water inlet shell supporting body 111 to the annular one-way valve water outlet shell supporting body 121 and are sequentially arranged. Namely, the sealing rubber head 140 is close to the check valve inlet housing 110, and the spring 150 is close to the check valve outlet housing 120. The inner diameter of the one-way valve water inlet shell 110 is larger than the outer diameter of the one-way valve water outlet shell 120, so that the positioning and fixing effects are achieved, and the installation is convenient.

It should be understood that in this embodiment, the inner diameter of the check valve inlet housing 110 is larger than the outer diameter of the check valve outlet housing 120, so as to perform the positioning and fixing function and effectively enhance the sealing effect, and in other embodiments, the inner diameter of the check valve inlet housing 110 may be equal to the outer diameter of the check valve outlet housing 120. The technical effect of one-way leakage stopping of the present embodiment can also be achieved, and is also within the protection scope of the present embodiment.

Referring to fig. 3-7, the annular one-way valve inlet housing supporting body 111 of the one-way valve inlet housing 110 is provided with a sealing ring positioning groove 112 for accommodating the sealing ring 130. The above-described seal ring positioning groove 112 enables the seal ring 130 to be restrained in the radial direction. Two clamping grooves 113 are symmetrically arranged on the one-way valve water inlet shell 110.

Referring to fig. 3-7 and 8, the one-way valve outlet housing 120 is recessed inward to form an annular one-way valve outlet housing support 121. And a sealing ring limiting table 122 is arranged on the outer side of one end of the annular one-way valve water inlet shell supporting body 111. The sealing ring positioning table 122 and the sealing ring positioning groove 112 cooperate to fix the sealing ring 130. The outer wall of the one-way valve outlet shell 120 is provided with a hook 123. The locking groove 113 and the locking hook 123 are matched to fasten the one-way valve water inlet shell 110 and the one-way valve water outlet shell 120.

It should be understood that in the present embodiment, the sealing ring 130 can be effectively fixed by the sealing ring positioning groove 112 and the sealing ring stopping table 122, and in other embodiments, only one of the two is needed, and the sealing ring 130 can also be fixed. Similarly, if the sealing ring positioning groove 112 and the sealing ring position-limiting table 122 are not provided, some fixing effects on the sealing ring 130 can be achieved by the pressing force between the check valve water inlet shell 110 and the check valve water outlet shell 120, and the technical effect of one-way leakage prevention of the embodiment can also be achieved, which are all within the protection scope of the embodiment. In this embodiment, the sealing is further realized by the sealing ring 130, in other embodiments, the sealing ring 130 may not be provided, and a certain sealing function is realized by the elastic characteristics of the one-way valve water inlet shell 110 and the one-way valve water outlet shell 120.

It should be noted that, in this embodiment, the number of the clamping slots 113 and the clamping hooks 123 is 2, in other embodiments, the number of the clamping hooks 123 and the clamping slots 113 may also be other, the number of the clamping slots 113 may also be more than the number of the clamping hooks 123, the clamping slots 113 may not be uniformly arranged on the check valve water inlet shell 110, and the technical effects of fastening the check valve water inlet shell 110 and the check valve water outlet shell 120 can be both achieved, all within the protection scope of this embodiment.

Referring to fig. 9, the sealant head 140 includes a head portion 141 and a tail step cylinder 142 connected to each other. The head 141 is movably connected to the annular check valve inlet housing support 111. The tail step cylinder 142 fits within the inner race of the spring 150. One end of the spring 150 away from the sealing rubber head 140 abuts against the annular check valve outlet housing support body 121.

Referring to fig. 10 and fig. 11, the working principle of the novel leak-stopping check valve structure 100 provided by the present invention is: when the water flows in the first direction 160, the sealing rubber head 140 is pressed under the pressure of the water and also moves in the first direction 160, and the spring 150 is compressed. The inner parts of the one-way valve water inlet shell 110 and the one-way valve water outlet shell 120 are elastically opened with the sealing rubber head 140 to form a gap, so that water flow can be conducted and flowed. When the water flow stops, the spring 150 moves along the second direction 170 under the action of the restoring force, and when the sealing rubber head 140 moves to the annular one-way valve water inlet shell supporting body 111, the insides of the one-way valve water inlet shell 110 and the one-way valve water outlet shell 120 are both in an elastic closing state with the sealing rubber head 140, so that the sealing of the whole novel leakage-stopping one-way valve structure 100 is realized.

In summary, the utility model provides a novel leak-stopping one-way valve structure, which realizes that when water flows in a first direction, the sealing rubber head is squeezed and opened to realize water flow circulation by the cooperation of the one-way valve water inlet shell, the one-way valve water outlet shell, the spring and the sealing rubber head; when rivers stopped, the head is the closed condition to the sealing rubber, realizes the sealed of whole novel leak-stopping check valve structure. Therefore, one-way water inlet and one-way water outlet can be realized, the defects of siphon, water leakage and the like of the pipeline can be prevented, and the conditions of different leakage stopping pressures, horizontal placement and vertical placement and inclined placement of different pipelines can be met.
