Abstract
The utility model discloses an electronic expansion valve, and belongs to the field of refrigeration accessories. An existing electronic expansion valve has the defect that a valve needle vacillates to the left and right due to the fact that a rotator shakes easily. The electronic expansion valve comprises a valve body, a rotor component and the valve needle, wherein the rotor component is arranged in a valve body inner cavity, an elastic part is arranged at the lower end of a valve rod on the rotor component, a spherical gasket integrally formed with the valve needle is arranged at the top of the valve needle, the spherical gasket abuts against the elastic part, and the upper end of the valve rod is fixed through a bearing so that the valve rod is prevented from transversely shaking when the valve rod is rotated. According to the electronic expansion valve, the upper end of the valve rod is fixed through the bearing, the lower end of the bearing makes contact with the valve needle through the elastic part and the spherical gasket, the impact of the valve rod to a valve hole wall is avoided, the flexibility of the valve needle is improved, and the valve needle is prevented from vacillating to the left and right due to influence of rotor motion in the working process.
Description
Technical field
The utility model belongs to refrigeration accessory field, especially relevant with the electric expansion valve on a kind of air-conditioning.
Background technology
The effect of the electric expansion valve on air-conditioning is the size that regulates the refrigerant flow of air-conditioning, and the operation principle of electric expansion valve is by driving mechanism valve needle, thereby controls the aperture of needle and valve opening, realizes the flow that regulates cold-producing medium.Because needle is to be directly fixedly mounted on the valve rod of valve needle, when needle with stem movement in the valve opening of valve seat, when needle coordinates with valve opening, now needle is due to limited, valve rod is due to inertia, and valve rod produces an impulsive force to valve opening, can be to valve opening inner wall abrasion under long-time.And rotor can produce vibrations while rotating unavoidably, thereby cause swinging of needle, produce error.
Utility model content
The purpose of this utility model is intended to overcome the easily vibrations and cause the wiggly defect of needle of rotor that existing electric expansion valve exists, while providing a kind of valve rod to rotate and do not affect the electric expansion valve of needle precision.
For this reason, the utility model is by the following technical solutions: a kind of electric expansion valve, comprise valve body, rotor part and needle, rotor part is arranged in body cavity, it is characterized in that, valve rod lower end on described rotor part arranges elastic component, described needle top is provided with spherical washer, and needle and spherical washer are integral type structure, and top and the elastic component of spherical washer lean, described valve rod upper end is fixed by bearing, prevents that transverse shakiness from appearring in valve rod while rotating.By adopting spherical washer between valve rod and needle, make to form point between valve rod and elastic component and contact, thus the impact of minimizing valve rod to needle, the flexibility that has improved needle.
As to technique scheme supplement and perfect, the utility model also comprises following technical characterictic.
Described elastic component is spring.
Use the utility model can reach following beneficial effect: the utility model is by fixing the upper end of valve rod by bearing, the lower end of bearing contacts with needle with spherical washer by spring, avoid the impact of valve rod to valve opening wall, and the flexibility that has improved needle, make needle not be subject to the impact of rotor rotation when work and swing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises valve body 6, rotor part 7 and needle 5, rotor part 7 is arranged in body cavity, valve rod lower end on rotor part 7 arranges elastic component 3, needle top is provided with spherical washer 4, needle 5 is integral type structure with spherical washer 4, the top of spherical washer 4 and elastic component 3 lean, as preferably, elastic component 3 is spring, described valve rod 2 upper ends are fixing by bearing 1, prevent that transverse shakiness from appearring in valve rod 2 while rotating, by adopting spherical washer 4 between valve rod 2 and needle 5, making to form point between valve rod 2 and spring contacts, thereby reduce the impact of 2 pairs of needles 5 of valve rod, improved the flexibility of needle 5.
