Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present embodiments more clearly, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 4, in an embodiment of the present invention, a high-strength intercooler air pipe includes a pipe body 1, where one end of the pipe body 1 is an air inlet 11, and the other end is an air outlet 12; still include check valve 2 and one end and air cleaner give vent to anger the pipe 3 that the end communicates, but the other end of pipe 3 passes through check valve 2 unilateral intercommunication in body 1 (promptly the gaseous accessible check valve 2 in the pipe 3 gets into inside body 1, but the inside gas of body 1 can not get into the inside of pipe 3 through check valve 2). The check valve 2 comprises a spring 21, a cone-shaped sealing plug 22, a cylindrical sleeve 23 and a cylindrical cover cap 24, the sleeve 23 and the cover cap 24 are connected to form a closed structure, the inner bottom of the sleeve 23 is welded and communicated with the pipe body 1 through an integrally connected connecting pipe 13, a cone-shaped through hole 25 for communicating the conduit 3 is arranged at the inner bottom of the cover cap 24, the sealing plug 22 is axially and movably connected into the cone-shaped through hole 25, the spring 21 is located between the inner bottom walls of the sealing plug 22 and the sleeve 23, and a partition area is formed between the conical surface on the sealing plug 22 and the inner wall of the cone-shaped through hole 25 under the action of the spring 21.

In the embodiment, the big end of the sealing plug 22 is integrally connected with a cylindrical limiting sliding plate 26, the outer side surface of the limiting sliding plate 26 is axially matched with the inner wall of the sleeve 23 in a sliding manner, and two ends of the limiting sliding plate 26 are provided with communication holes 27 in a penetrating manner. Under the limit sliding matching of the limit sliding plate 26 and the inner wall of the sleeve 23, the stability of the axial movement of the sealing plug 22 along the circular truncated cone-shaped through hole 25 is improved.

In an embodiment, the communication holes 27 are plural, and the plurality of communication holes 27 are radially arranged, so that the gas in the conduit 3 can more uniformly enter the inside of the tube body 1.

In an embodiment, the cap 24 is detachably connected to the sleeve 23, preferably by a screw connection or a snap connection (both screw and snap connections are known per se), which facilitates replacement and maintenance.

In the embodiment, the conduit 3 is a bendable pipe, so that the installation and routing are convenient, and other parts are convenient to avoid.

The working principle is as follows: when the pipe body 1 does not work, the air pressures at the two ends of the check valve 2 are the same, the sealing plug 22 can axially move into the circular truncated cone-shaped through hole 25 under the elastic action of the spring 21 and the limiting action of the limiting sliding plate 26, and at the moment, because a partition area is formed between the conical surface on the sealing plug 22 and the inner wall of the circular truncated cone-shaped through hole 25, the check valve 2 is in a closed state, so that the air in the pipe body 1 is prevented from entering the guide pipe 3. When the pipe body 1 works, because the flow velocity inside the pipe body 1 is increased (according to the principle that the pressure intensity is reduced when the flow velocity is larger), pressure difference is generated at two ends of the check valve 2, the sealing plug 22 is axially far away from the circular truncated cone-shaped through hole 25 under the action of the pressure difference, so that the conical surface on the sealing plug 22 is separated from the inner wall of the circular truncated cone-shaped through hole 25, and air filtered by the air filter sequentially passes through the guide pipe 3, the circular truncated cone-shaped through hole 25, the communication hole 27 and the connecting pipe 13 and then enters the pipe body 1 and is mixed with high-temperature gas in the pipe body 1, so that the temperature of the gas inside the pipe body 1 is greatly reduced, the heat radiation quantity of the pipe body 1 is reduced, and the service life of parts made of rubber, plastics and other materials around the pipe body 1 is.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
