The electronic expansion valve comprises a valve body and a coil, wherein a concave hull is arranged at the upper part of the valve body, a convex hull corresponding to the concave hull is arranged at the lower part of the coil, and the convex hull and the concave hull are mutually and tightly matched, and the electronic expansion valve further comprises a fixing frame respectively connected with the valve body and the coil. The fixing frame comprises an upper fixing plate and a lower fixing plate, the upper fixing plate and the lower fixing plate are buckled through a buckle, and an arc-shaped bayonet is arranged on the upper fixing plate and is clamped with the coil; an arc bayonet is arranged on the lower fixing plate and is tightly clamped with the valve body. The utility model discloses on original technical basis, owing to increased a fixed plate, its upper fixed plate bayonet socket and coil straining, and bottom plate bayonet socket and valve body straining have the buckle lock again between the upper and lower fixed plate to play the effect of fixed coil and valve body relative position, make both difficult separation, guarantee electronic expansion valve's normal work.
Description
Technical field
The utility model relates to a kind of aircondition, particularly the expansion valve in the air-conditioning.
Background technique
Air conditioner electronic expansion valve is mainly used in the varying duty air-conditioning system, realizes the automatic adjusting of refrigerant flow, moves thereby air-conditioning system is remained under the best operating mode, reaches purposes such as fast-refrigerating, temperature are accurately controlled, power saving.Can also be used for other controls.This valve has reversibility, can realize freezing, heating the automatic control of state down-off.Most of idle call electronics expansion valve structurally is divided into valve body and two parts of coil, cooperatively interacts by the recessed bag of convex closure on the coil and valve body top when both assemble and is fixed.For various reasons, the for example vibrations in transportation, the installation process, convex closure is separated with recessed bag cause solid failure, cause coil can't allow the interior needle of valve body move, cause electronic expansion valve regulation failure, as one of core devices in the air-conditioner control system, the fault of electric expansion valve could make control system can't realize the predetermined control logic, and therefore air-conditioning system also can't enable!
The model utility content
Technical problem to be solved in the utility model is, a kind of electric expansion valve of high reliability is provided.
Technical problem to be solved in the utility model is achieved by the following technical solution: a kind of electric expansion valve is provided, it comprises valve body and coil, one recessed bag is arranged at this valve body top, the coil bottom is provided with a convex closure corresponding with above-mentioned recessed bag, this convex closure and recessed bag closely cooperate mutually, wherein, this electric expansion valve comprises that also one connects the fixing frame of this valve body and coil respectively.This fixing frame comprises upper mounted plate and bottom plate, this upper mounted plate and bottom plate by the buckle button and, have an arc bayonet socket and coil to tighten on the upper mounted plate; One arc bayonet socket and valve body chucking is arranged on the bottom plate.
The utility model is on original technical foundation, owing to increased by a fixed plate, its upper mounted plate bayonet socket and coil fastening, and bottom plate bayonet socket and valve body fastening, there is buckle to fasten between the last bottom plate again, thereby play the effect of fixed coil and valve body relative position, make both not easily separated, guarantee the proper functioning of electric expansion valve; In addition, lower fixed frame fastens by buckle on this fixed plate, and novel light and handy in the design, installation and removal are all very convenient, taken into full account the needs of production, installation and maintenance, and with low cost.
