Abstract
The utility model discloses a built-in coil structure of a gasoline engine electric EGR valve. The built-in coil structure of the gasoline engine electric EGR valve comprises arranged coil skeletons. Copper wires are wound on the coil skeletons. The end portions of the copper wires are welded on coil male tabs. A coil outer seal package is arranged on the inner wall of an outer shell of the electric EGR valve. The bottom end of the coil outer seal package is fixedly connected with the bottom ends of the coil skeletons. The top end of the coil outer seal package is connected with a displacement sensor in an abutting mode. Grooves which are used for clamping the coil male tabs are further formed in the inner wall of the coil outer seal package. The built-in coil structure of the gasoline engine electric EGR valve is simple in structure. Due to the fact that the coil outer seal package is used for packaging the coil skeletons of the electric EGR valve, the copper wires wound on the coil skeletons and welding spots between the copper wires and the coil male tabs, erosion of water and oil is effectively prevented, the phenomenon that weld between the coil male tabs and the copper wires is not firm because of vibration of an engine can be effectively prevented from happening, reliability of the electric EGR valve is greatly improved, and good running of the whole system is effectively ensured.
Description
Technical field
The utility model relates to a kind of loop construction, particularly a kind of loop construction for the electronic EGR valve of petrol engine.
Background technique
The basic principle of waste gas recirculation is that air inlet is introduced in the part exhaust, to improve combustion performance, reduces formation and the discharge amount of NOx in the engine exhaust, reduces exhaust pollution.Electronic EGR valve is one and is installed in the electromechanical integrated product that is used for controlling the amount of exhaust gas recirculation that feeds back to gas handling system on the petrol engine motor, and the internal coil in the electronic EGR valve is exactly to control the vitals of electronic EGR valve opening and link to each other with electronic EGR valve position displacement sensor.The internal coil of electronic EGR valve is installed in electronic EGR valve inside, because electronic EGR valve will be worked under rugged environment for a long time, copper cash in the electronic EGR valve internal coil can be subjected to the erosion of water and oil all the time and corrode, thereby makes that electronic EGR valve is ineffective in whole system; And electronic EGR valve internal coil copper cash is welded on the EGR valve coil inserted sheet, link to each other with contact pin on the electronic EGR valve position displacement sensor again, because electronic EGR valve is installed on the motor, motor is in vibrational state always, electronic EGR valve internal coil is in vibrational state too, the copper cash weld comes off easily, ruptures, thereby makes that electronic EGR valve is ineffective in whole system.
Summary of the invention
The technical problem that the utility model solves provides the internal coil structure of the electronic EGR valve of a kind of petrol engine, have waterproof, oil-resistant function, can also avoid causing because of engine luggine the generation of copper cash and coil inserted sheet phenomenon of rupture, for the reliability of electronic EGR valve provides guarantee.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
The internal coil structure of the electronic EGR valve of petrol engine, comprise the coil rack that is arranged in the electronic EGR valve shell, be wound with copper cash on the coil rack, the end of described copper cash is welded on the coil inserted sheet, the outer casing inner wall of described electronic EGR valve is provided with coil and seals outward, fixedly connected with the bottom of coil rack in the bottom that described coil is sealed outward, the displacement transducer apical grafting of the top that coil is sealed outward and electronic EGR valve; Also be provided with the groove that clamps the coil inserted sheet outward on the inwall that described coil is sealed.
Owing to adopted above technological scheme, the obtained technological progress of the utility model is as follows.
The utility model is simple in structure, seal the coil rack of electronic EGR valve outward, be wound on copper cash on the coil rack and the solder joint of copper cash and coil inserted sheet is encapsulated by being arranged on coil on the outer casing inner wall, thereby make the whole internal coil of electronic EGR valve all to be encapsulated in outer the sealing, effectively prevented the erosion of water, oil; The coil inserted sheet that is welded with the copper cash joint is installed in the outer groove of sealing, can effectively prevent from causing coil inserted sheet and copper cash not prison welding by the generation of phenomenon because of engine luggine, improve the reliability of electronic EGR valve greatly, thereby effectively guaranteed the good operation of whole system.
Description of drawings
Fig. 1 is the partial sectional view of the electronic EGR valve of the utility model.
Wherein: 1, electronic EGR valve, 2, displacement transducer, 2-1, contact pin, 3, internal coil, 3-1, coil rack, 3-2, coil inserted sheet, 3-3, coil are sealed outward.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further elaborated.
Electronic its structure of EGR valve of a kind of petrol engine as shown in Figure 1.Its internal coil 3 comprises that coil rack 3-1, copper cash, coil inserted sheet 3-2 and coil seal 3-3 outward, and coil rack 3-1 is arranged in the shell of electronic EGR valve, and the copper cash wire-wound is on ring framework 3-1, and the two ends of copper cash are welded on the coil inserted sheet 3-2; The coil inserted sheet is connected with the contact pin 2-1 of displacement transducer.
Coil is sealed outward on the outer casing inner wall that 3-3 is arranged on electronic EGR valve, fixedlys connected with the bottom of coil rack 3-1 in the bottom that coil is sealed 3-3 outward, and coil is sealed the top of 3-3 and displacement transducer 2 apical graftings of electronic EGR valve outward.
Also be provided with groove outward on the inwall that coil is sealed, be used for clamping coil inserted sheet 3-2, the solder joint of copper cash and coil inserted sheet is installed in the groove, prevent from causing the damage of electronic EGR valve because engine luggine ruptures coil inserted sheet and copper cash.
Claims (1)
1. the internal coil structure of the electronic EGR valve of petrol engine, comprise the coil rack (3-1) that is arranged in the electronic EGR valve shell, be wound with copper cash on the coil rack (3-1), the end of described copper cash is welded on the coil inserted sheet (3-2), it is characterized in that: the outer casing inner wall of described electronic EGR valve is provided with coil and seals (3-3) outward, fixedly connected with the bottom of coil rack (3-1) in the bottom that described coil is sealed (3-3) outward, coil is sealed the top of (3-3) and the displacement transducer apical grafting of electronic EGR valve outward; Also be provided with the groove that clamps coil inserted sheet (3-2) outward on the inwall that described coil is sealed.
