Abstract
The utility model relates to a small electronic expansion valve which is used for controlling the flow of the coolant. The existing miniaturisation electronic expansion valve is limited by the structure; the cross sectional area drops obviously, but the height is on the high side; so, the time for the air-conditioning is occupied, and the center of gravity is on the high side, after the installation of the valve; and the system vibration resistance is poor. The utility model comprises a valve body, a coil sheathed on the valve body, a valve seat connected to the lower part of the valve body, a magnetic rotor positioned in the valve body, a screw mandrel positioned in the valve body, a stopper positioned in the valve body and a stop rod positioned in the valve body; a screw nut fixed on the valve seat is screwed outside the screw mandrel. The small electronic expansion valve is characterized in that the screw mandrel is arranged at the mid upper part of the magnetic rotor; so, the magnetic rotor is formed into an upper chamber and a lower chambers; the screw nut is arranged in the lower chamber of the magnetic rotor. The upper end of the stopper is fixed on the top wall in the valve body; the lower part of the stop rod matched with the stopper is connected to the end face of the screw mandrel. With the utility model, the miniaturisation of the valve is realized; the vibration resistance is ensured to be high; and the safety performance of the refrigeration system is high.
Description
Technical field
The utility model relates to the parts of idle call, specifically a kind of electric expansion valve of controlling cold medium flux.
Background technique
Along with the miniaturization of air-conditioning, the electric expansion valve miniaturization of control cold medium flux also progressively is in miniaturization.The electric expansion valve of former miniaturization is subjected to the restriction of structure, though cross-section area significantly descend, highly higher, not only taken the space of air-conditioning preciousness, it is higher to make that also valve is installed tailheaviness, anti-system vibration is poor, brings potential safety hazard to system.
The model utility content
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and a kind of valve body center of gravity and highly low electric expansion valve are provided, and resistance to shock is strong when realizing the electric expansion valve miniaturization.
The technical solution of the utility model is as follows: the miniature electric expansion valve, comprise valve body, be enclosed within the coil on the valve body and be connected the valve seat of valve body lower portion, be positioned at magnet rotor, screw mandrel, stopper and the stop rod of valve body, screw mandrel is bolted with the nut that is fixed on the valve seat outward, it is characterized in that described screw mandrel is arranged on the middle and upper part of magnet rotor, make magnet rotor form upper and lower two Room, nut is hidden in the following indoor of magnet rotor; The upper end of stopper is fixed on the interior roof of valve body, and the stop rod bottom that cooperates with stopper is connected on the end face of screw mandrel.The utility model is divided into upper and lower two Room with the inner chamber of magnet rotor, magnet rotor when motion, stopper partly can be hidden into, thereby realized the miniaturization of valve body; Reduced the center of gravity of magnet rotor, just reduced the center of gravity of valve body, resistance to shock is strong when realizing the valve miniaturization, the Safety performance height of refrigeration system.
Described miniature electric expansion valve, the end face of screw mandrel is higher than the bottom surface of chamber on the magnet rotor, and the heat radiation when being used for riveted joint of screw mandrel and stop rod or spot welding prevents to destroy magnet rotor; In addition, the mould of magnet rotor is more simplified.
Described miniature electric expansion valve, the top of screw mandrel are provided with the shape of threads groove that is used to strengthen with the magnet rotor join strength.
Described miniature electric expansion valve, be positioned at the external diameter of the screw mandrel light section external diameter of shape of threads groove below less than groove, the magnet rotor place that cooperates with screw mandrel forms a bulge loop, this bulge loop is conflicted on the light section of groove bottom and screw mandrel, make magnet rotor and screw mandrel form closure, increased injection moulding intensity and the mold design of having simplified magnet rotor.
The utility model is divided into upper and lower two Room with magnet rotor, has reduced the height and the center of gravity of valve body, has both realized the miniaturization of valve, has guaranteed that again its resistance to shock is strong, the Safety performance height of refrigeration system.
