Abstract
The utility model discloses an automobile water return pipe comprising a main pipe (1) and a branch pipe (2), the lower end of the branch pipe (2) is integrally welded on a pipe wall of the main pipe (1), and manometer joints (3) are provided on the pipe walls of the main pipe (1) and the middle part of the branch pipe. The other end of the main pipe (1) is provided with a welding-free flange (5) in a close fitting manner, the middle part of the main pipe (1) is provided with a fixing support (4) for installation, and installation parts fit with dustproof caps are provided at upper ends of the main pipe (1) and the branch pipe (2). The cost of the automobile water return pipe is low, and the pipe facilitates pressure tests.
Description
Technical field
The utility model relates to automobile pipeline field, particularly a kind of automobile return pipe.
Background technique
The automobile return pipe is one of important pipeline in the automobile pipeline.The automobile return pipe of prior art mainly comprises a person in charge and a looped pipeline, and looped pipeline normally is connected on the person in charge by tee union, and inconvenience is installed, and cost is higher.And owing to when maintenance or detection system, can carry out pressure test etc. to pipeline, need manometer etc. be installed in pipeline, therefore, take over the road in addition to test, operation is trouble very, reduces working efficiency greatly.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of cost low, automobile return pipe very easily when carrying out pressure test.
The technical scheme in the invention for solving the above technical problem is: a kind of automobile return pipe comprises and being responsible for and looped pipeline that the lower end integral type of described looped pipeline is welded in the person in charge's tube wall, and is equipped with the manometer interface on the tube wall at the described person in charge and looped pipeline middle part; The described person in charge's the other end drive fit is equipped with exempts to weld flange, and the described person in charge's middle part is provided with for the fixed support of installing; The upper end of the described person in charge and looped pipeline is equipped with the assembly department that matches for dust cap.
Described assembly department mainly is made up of the bulge loop and the plane of inclination that are used for matching with dust cap, and the angle between plane of inclination and the tube wall is 11 °.
Compared with prior art, advantage of the present utility model is: the lower end integral type of the looped pipeline of this automobile return pipe is welded in the person in charge's outer circumferential face.Like this, easier for installation, provide cost savings, and be equipped with the manometer interface on the outer circumferential face at the person in charge and looped pipeline middle part, very convenient when carrying out pressure test, high working efficiency.The other end drive fit of being responsible for is equipped with exempts to weld flange, has avoided the weld defects of hubbed flange of the hubbed flange of existing downhand welding and butt welding and the problem that welding heat affected territory annular is concentrated.The middle part of being responsible for is provided with for the fixed support of installing, this return pipe easier for installation.And the upper end of the person in charge and looped pipeline is equipped with the assembly department that matches for dust cap, and the installation of dust cap is more firm.
Description of drawings
The structural representation of Fig. 1 the utility model automobile return pipe.
The A-A sectional structure schematic representation of Fig. 2 Fig. 1.
Among Fig. 1-2: 1 person in charge, 2 looped pipelines, 3 manometer interfaces, 4 fixed supports, 5 exempt to weld flange, 6 bulge loops, 7 plane of inclination.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, 2, a kind of automobile return pipe comprises the person in charge 1 and looped pipeline 2, and the lower end integral type of described looped pipeline 2 is welded in is responsible for 1 tube wall, and is equipped with manometer interface 3 on the tube wall at the described person in charge 1 and looped pipeline 2 middle parts; The described person in charge's 1 the other end drive fit is equipped with exempts to weld flange 5, and the described person in charge's 1 middle part is provided with for the fixed support of installing 4; The upper end of the described person in charge 1 and looped pipeline 2 is equipped with the assembly department that matches for dust cap.
Described assembly department mainly is made up of the bulge loop 6 and the plane of inclination 7 that are used for matching with dust cap, and the angle between plane of inclination 7 and the tube wall is 11 °.
Describedly exempt to weld the hole wall of flange 5 along being circumferentially with a plurality of locating slots.Can effectively prevent the slip of pipe fitting, soundness is better.
Below only be described with regard to most preferred embodiment of the present utility model, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.All various variations of doing in the protection domain of the utility model independent claims are all in the utility model protection domain.
Claims (3)
1. automobile return pipe, comprise the person in charge (1) and looped pipeline (2), it is characterized in that: the lower end integral type of described looped pipeline (2) is welded in the tube wall of the person in charge (1), and is equipped with manometer interface (3) on the tube wall at the described person in charge (1) and looped pipeline (2) middle part; The described person in charge's (1) the other end drive fit is equipped with exempts to weld flange (5), and the described person in charge's (1) middle part is provided with for the fixed support of installing (4); The upper end of the described person in charge (1) and looped pipeline (2) is equipped with the assembly department that matches for dust cap.
2. automobile return pipe according to claim 1 is characterized in that: described assembly department mainly is made up of the bulge loop (6) and plane of inclination (7) that are used for matching with dust cap, and the angle between plane of inclination (7) and the tube wall is 11 °.
