Description

Technical Field

[0001] The utility model relates to a check valve, and more particularly to a structure of a right-angle check valve for an automobile. Background Art

[0002] There are various liquid pipelines inside an automobile, and some liquids are not allowed to flow back. Therefore, in the prior art, there are multiple check valves in the liquid pipelines of the automobile to prevent the liquid from flowing back.

[0003] Currently, due to the very limited space inside the automobile, most of the check valves used inside the existing automobiles are made of PVC material. The existing PVC check valves have cylindrical and angled shapes to achieve the straight-through and corner of the pipeline liquid. The valve core component inside the cylindrical check valve is a duckbill valve core to adapt to the relatively limited space inside the cylindrical check valve. The angled shape realizes one-way flow by using a valve plate that can be turned up and down. However, the above valve plate mainly realizes it by gravity. Therefore, when the installation is not in place and the liquid viscosity is relatively high, it is easy for the valve plate to be difficult to reset, and then the one-way flow fails. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a structure of a right-angle check valve for an automobile that is not prone to one-way flow failure.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: A structure of a right-angle check valve for an automobile, including a valve body, a liquid inlet interface, a liquid outlet interface, and a valve core assembly disposed inside the valve body for connecting and blocking the liquid inlet interface and the liquid outlet interface. The valve core assembly includes a closing member and a supporting member. An inlet liquid channel and an outlet liquid channel are provided inside the valve body. The inlet liquid channel and the outlet liquid channel are distributed at a right angle. One end of the inlet liquid channel is connected to the liquid inlet interface, and the other end is connected to the outlet liquid channel. The other end of the outlet liquid channel relative to the inlet liquid channel is connected to the liquid outlet interface. The closing member is disposed at the connection between the inlet liquid channel and the outlet liquid channel. The supporting member abuts against the channel wall of the outlet liquid channel to push the closing member towards the inlet liquid channel, thereby disconnecting the connection between the inlet liquid channel and the outlet liquid channel through the closing member.

[0006] As a further improvement of the present utility model, the inlet liquid channel is vertically disposed inside the valve body, the outlet liquid channel is horizontally disposed inside the valve body, the liquid inlet interface is disposed on the lower end face of the valve body, the liquid outlet interface is disposed on the side wall of the valve body, the closing member is in a bowl shape, the bowl opening of the closing member is upward, the supporting member is a spring piece, one end of the spring piece is fixed to the edge of the bowl opening of the closing member, and the other end abuts against the upper channel wall of the outlet liquid channel.

[0007] As a further improvement of the present utility model, an arc-shaped slope is formed on the lower channel wall of the liquid outlet channel.

[0008] As a further improvement of the present utility model, a plurality of sealing rings are coaxially sleeved on the liquid inlet interface, and the plurality of sealing rings are arranged in an inverted frustum shape.

[0009] The beneficial effects of the present utility model are as follows. By providing a valve body, a liquid inlet interface, a liquid outlet interface and a valve core assembly, a right-angle one-way valve structure can be simply and effectively formed. By setting the valve core assembly into a closing member and a supporting member, the liquid inlet channel and the liquid outlet channel can be blocked or communicated by the closing member. By using the supporting member to assist the closing member in blocking the liquid inlet channel and the liquid outlet channel, the problem that the closing member cannot be reset in place due to the use of the gravity reset method in the prior art can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 is a schematic structural diagram of the right-angle one-way valve structure of the present utility model;

[0011] Figure 2 is Figure 1 a schematic structural diagram of the valve core assembly in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The following will further elaborate on the present utility model in conjunction with the embodiments given in the drawings.

[0013] Refer to Figures 1 to 2As shown in the figure, a right-angle one-way valve structure for an automobile in this embodiment includes a valve body 1, a liquid inlet interface 2, a liquid outlet interface 3, and a valve core assembly 4 disposed in the valve body 1 for connecting and blocking the liquid inlet interface 2 and the liquid outlet interface 3. It is characterized in that: the valve core assembly 4 includes a closing member 41 and a support member 42. An inlet liquid channel 5 and an outlet liquid channel 6 are provided in the valve body 1. The inlet liquid channel 5 and the outlet liquid channel 6 are distributed at a right angle. One end of the inlet liquid channel 5 is connected to the liquid inlet interface 2, and the other end is connected to the outlet liquid channel 6. The other end of the outlet liquid channel 6 relative to the inlet liquid channel 5 is connected to the liquid outlet interface 3. The closing member 41 is disposed at the connection between the inlet liquid channel 5 and the outlet liquid channel 6. The support member 42 abuts against the channel wall of the outlet liquid channel 6 to push the closing member 41 towards the inlet liquid channel 5, thereby disconnecting the connection between the inlet liquid channel 5 and the outlet liquid channel 6 through the closing member 41. During the process of using the one-way valve structure of this embodiment, it only needs to be connected to the internal pipeline of the automobile through the liquid inlet interface 2 and the liquid outlet interface 3. Then, during the startup of the automobile, the liquid will enter the inlet liquid channel 5 through the liquid inlet interface 2, and then enter the outlet liquid channel 6 through the inlet liquid channel 5. When the liquid flows from the inlet liquid channel 5 to the outlet liquid channel 6, the liquid pushes the closing member 41 to move, and the support member 42 deforms, so as to realize the one-way flow of the liquid. In this way, compared with the prior art in which the valve plate is reset by gravity, the problem of the one-way valve failure caused by the incomplete reset of the valve plate in the prior art can be effectively avoided.

[0014] As a specific improvement implementation, the inlet liquid channel 5 is vertically arranged in the valve body 1, the outlet liquid channel 6 is horizontally arranged in the valve body 1, the liquid inlet interface 2 is arranged on the lower end surface of the valve body 1, the liquid outlet interface 3 is arranged on the side wall of the valve body 1, the closing member 41 is in a bowl shape, and the bowl mouth of the closing member 41 is upward. The support member 42 is a spring sheet. One end of the spring sheet is fixed to the edge of the bowl mouth of the closing member 41, and the other end abuts against the upper channel wall of the outlet liquid channel 6. By setting the closing member 41 in a bowl shape in the above way, on the one hand, the hard seal can be realized by the way that the arc edge of the bowl shape abuts against the ends of the inlet liquid channel 5 and the outlet liquid channel 6. After the liquid enters the inlet liquid channel 5, the liquid can better enter the outlet liquid channel 6 through the place where the arc surface of the closing member 41 abuts against the ends of the inlet liquid channel 5 and the outlet liquid channel 6, so as to push open the closing member 41 and at the same time deform the support member 42, thus realizing the effect of one-way flow. When the liquid wants to enter the inlet liquid channel 5 from the outlet liquid channel 6, the liquid will be collected by the bowl mouth of the closing member 41, so as to better push the closing member 41 to squeeze towards the inlet liquid channel 5, so as to better prevent the liquid from entering the inlet liquid channel 5 from the outlet liquid channel 6.

[0015] As a specific implementation of the improvement, an arc-shaped slope is formed on the lower channel wall of the liquid outlet channel 6. Through the setting of the slope, the liquid can be further prevented from entering the liquid inlet channel 5 from the liquid outlet channel 6, making the one-way fluidity of the one-way valve better.

[0016] As a specific implementation of the improvement, a plurality of sealing rings are coaxially sleeved on the liquid inlet interface 2, and the plurality of sealing rings are arranged in an inverted frustum shape. Through the setting of the sealing rings, better sealing performance can be achieved when the liquid inlet interface 2 is connected to the external pipeline.

[0017] In summary, for the structure of the right-angle one-way valve of the vehicle in this embodiment, by forming the valve core assembly 4 with the closing member 41 and the supporting member 42, the reset of the closing member 41 can be realized by the deformation of the supporting member 42. In this way, compared with the method of using gravity to realize the reset of the valve plate in the prior art, the problem of one-way flow failure caused by incomplete reset can be avoided.

[0018] The above are only the preferred implementation modes of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications should also be regarded as the protection scope of the present invention.
