Abstract
The utility model discloses a four-way pipe, which comprises a first branch pipe (1) and a second branch pipe (2) that are transversely arranged, a third branch pipe (3) that is vertically arranged and a fourth branch pipe (4) that is obliquely arranged, wherein a plurality of annular convex tendons (5) are arranged on the outer circumferential surface of the end of each of the first branch pipe (1), the second branch pipe (2) and the third branch pipe (3). Since a plurality of annular convex tendons (5) are arranged on the outer circumferential surface of the end of each of the first branch pipe (1), the second branch pipe (2) and the third branch pipe (3), during mounting, the branch pipes of the four-way pipe are not easy to fall off due to enlarged friction force between the branch pipes and a cooling water pipe. Also, the annular convex tendons have good sealing effect, so that leakage between the cooling water pipe and the branch pipes of the four-way joint is not easy to occur, and the normal operation of an engine is not affected.
Description
Technical field
The utility model relates to the pipe fitting field, particularly a kind of four-way pipe.
Background technique
Overheated in order to prevent motor car engine, adopt water-cooling tube as the passage that transmits the cooling water between motor and the radiator usually.In the water-cooling tube system, when flow changes, adopt the reducer pipe pipeline that is connected in series just can achieve the goal usually, and four-way pipe is one of reducer pipe of using always.During installation, water-cooling tube is linked in respectively on the termination of each arm of four-way pipe, the effect of axial limiting can be played in the termination, but because the fit between the termination of each arm of water-cooling tube and four-way pipe is directly to advance directly, in case the pipe internal pressure is excessive, just might occur coming off.So also need to take other security measure, as with iron wire or anchor ear etc. with the water-cooling tube banding on the termination of arm.But problem is, no any seal approach between each arm of water-cooling tube and four-way pipe, and its sealing is relatively poor, easily leaks, and can influence the proper functioning of motor when serious.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of better tightness that makes between water-cooling tube and each arm is difficult for the four-way pipe that generation is leaked.
The technical scheme in the invention for solving the above technical problem is: a kind of four-way pipe, comprise first arm and second arm, vertical the 3rd arm that is provided with and the 4th arm of oblique setting of cross setting, be equipped with some annular convex ribs on the outer peripheral surface of the end of described first arm, second arm and the 3rd arm.
Compared with prior art, advantage of the present utility model is: be equipped with some annular convex ribs on the outer peripheral surface of the end of first arm of this four-way pipe, second and the 3rd arm.Like this, during installation, each arm of this four-way pipe and the frictional force of water-cooling tube strengthen, difficult drop-off.And annular convex rib can play good seal action, is difficult between water-cooling tube and the cross fitting arm leaking, and can not influence the proper functioning of motor.
As preferably, be equipped with circumferential stiffening rib on described first arm, second arm and the 3rd arm.Like this, strengthen the intensity of first arm, second arm and the 3rd arm, prevented fracture.
As preferably, be provided with an end between described second arm and the 4th arm and be sleeved on reinforcer on the 4th arm.Like this, can effectively strengthen the intensity of the 4th arm of diameter minimum and oblique setting, prevent that it from rupturing.
Description of drawings
Accompanying drawing is the structural representation of the utility model four-way pipe.
1 first arm, 2 second arms, 3 the 3rd arms, 4 the 4th arms, 5 annular convex ribs, 6 circumferential stiffening ribs, 7 reinforcers.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in drawings, a kind of four-way pipe, comprise first arm 1 and second arm 2, vertical the 3rd arm 3 that is provided with and the 4th arm 4 of oblique setting of cross setting, be equipped with some annular convex ribs 5 on the outer peripheral surface of the end of described first arm 1, second arm 2 and the 3rd arm 3.
Be equipped with circumferential stiffening rib 6 on described first arm 1, second arm 2 and the 3rd arm 3.
Be provided with an end between described second arm 2 and the 4th arm 4 and be sleeved on reinforcer 7 on the 4th arm 4.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model not only is confined to above embodiment, and its concrete structure allows variation.All various variations of being done in the protection domain of the utility model independent claims are all in the utility model protection domain.
Claims (3)
1. four-way pipe, comprise first arm (1) and second arm (2), vertical the 3rd arm (3) that is provided with and the 4th arm (4) of oblique setting of cross setting, it is characterized in that: be equipped with some annular convex ribs (5) on the outer peripheral surface of the end of described first arm (1), second arm (2) and the 3rd arm (3).
