Description
Technical Field
The utility model belongs to the technical field of the gasoline engine, concretely relates to novel EGR valve connecting pipe assembly structure.
Background
At present, the EGR system pipeline design of the existing gasoline engine is a connecting pipe which is designed independently basically in order to facilitate pipeline connection and meet the requirement of pipeline design, other related connectors need to be provided with parts for installation, thus the design cost and the development cost are increased, and the reliability of plugging or using is also reduced. The design of the EGR pipeline also needs to consider the design of an EGR valve for preventing condensed water from flowing back, and the risk of icing of the EGR valve is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel EGR valve connecting pipe assembly structure to the different demands of electricity injection system, II integrated EGR temperature sensor mount tables of ring flange are equipped with horizontal ponding section simultaneously at I middle parts of EGR pipe, prevent the comdenstion water EGR valve that flows back. The utility model discloses both satisfied the designing requirement, reduced engine outside profile volume again to simple structure uses easy maintenance, reduces development cost.
Realize above-mentioned purpose, the utility model discloses the technical scheme who takes is:
a novel EGR valve connecting pipe assembly structure comprises an EGR pipe I, an EGR pipe II, a flange plate I and a flange plate II; the flange II includes II bodies of flange dish and tee bend interfaces, the tee bend interface is fixed on II bodies of flange dish, wherein two interfaces of tee bend interface respectively with EGR pipe I and II one end welding of EGR pipe and intercommunication, a remaining interface installation temperature sensor mount table, I other end of EGR pipe and I welding of flange dish to with the connecting hole intercommunication that is equipped with on the flange dish I, I middle part of EGR pipe is equipped with horizontal ponding section, flange dish I is connected with the EGR valve.
The utility model discloses beneficial effect for prior art is: in a smaller assembly space, the EGR temperature sensor mounting platform is designed to meet the functional requirements without increasing the overall size of the external profile of the engine, and is integrated on the flange plate II, so that the EGR temperature sensor mounting platform is simple in structure and convenient to use and maintain. I design level ponding section of EGR pipe prevents the comdenstion water backward flow EGR valve.

Detailed Description
The technical solution of the present invention is further described in detail below with reference to the embodiments and the accompanying drawings, but not limited thereto, and all modifications or equivalent replacements of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be covered by the protection scope of the present invention.
The first embodiment is as follows: as shown in fig. 1-4, the present embodiment discloses a novel EGR valve connection pipe assembly structure, which includes an EGR pipe i 2, an EGR pipe ii 5, a flange i 1, and a flange ii 4; ring flange II 4 includes II bodies of ring flange and tee bend interfaces, the tee bend interface is fixed on II bodies of ring flange, wherein two interfaces of tee bend interface respectively with EGR pipe I2 and II 5 one end welding of EGR pipe and intercommunication, a remaining interface installation temperature sensor mount table, the I2 other end of EGR pipe and I1 welding of ring flange to with the connecting hole intercommunication that is equipped with on the ring flange I1, I2 middle parts of EGR pipe are equipped with horizontal ponding section (the equal slope of other parts of EGR pipe I2 sets up), ring flange I1 is connected with the EGR valve.
Further, an EGR pipe bracket 3 (which plays a role in supporting the EGR pipe I2) is fixed on the EGR pipe I2.
Further, the EGR pipe I2 and the EGR pipe II 5 form an air inlet channel.
When the engine works normally, combustion exhaust gas flows into an intake manifold (the intake manifold is connected with the EGR pipe II 5) through an intake passage formed by the EGR pipe I2 and the EGR pipe II 5. Connecting line is longer, plays the effect that reduces exhaust gas temperature, and EGR pipe I2 middle design horizontal segment prevents that the comdenstion water from flowing back the EGR valve. The EGR temperature sensor mounting table is integrated on the flange plate II 4, so that temperature measurement is accurate, newly-added parts are avoided, cost is saved, space is saved, and mounting is convenient.
