Abstract
The utility model provides a combined rod piece, which aims at shortcomings in prior art that core irons in sleeves are easy to block and solenoid electric valves easily have faults due to integral rod pieces of the solenoid electric valves of compressors. The combined rod at least comprises a rod piece 1 and a rod piece 2, wherein at least one end surface of the rod piece 1 is a convex spherical surface, and the rod 1 and the rod 2 are coaxially connected via the convex spherical surface. After adopting the combined rod piece, a solenoid electric valve and a compressor, the rod pieces are split types, and the rod pieces are contacted with one another via the spherical surfaces, so that the rod pieces are flexibly connected and easily centered; and the overall precision of the rod piece is improved while the process precision of the rod piece is reduced, so that the core irons can smoothly slide in the sleeves and can not be easy to block.
Description
Technical field
The utility model relates to the combined type rod member that a kind of rod member, particularly solenoid electric valve use.
Background technique
Control valve is the crucial controlling component that carries out displacement variation in variable compressor.What extensively adopt at present is internal control valve, and it is to utilize Compressor Discharge Pressure and pressure of inspiration(Pi) to regulate compressor crankcase pressure, thereby regulates the piston stroke of compressor and then the piston swept volume of change compressor, realizes the capacity regulating of refrigeration system.The solenoid electric valve of existing compressor with variable displacement because its core iron valve rod is whole rod member, when core iron and valve rod are press-fitted, has high coaxality and perpendicularity requirement to core iron and valve rod.By the structure of existing rod member, need the coaxality of valve rod and core iron to reach 0.02mm, when perpendicularity reaches 0.05mm, core iron is free to slide in sleeve pipe.Because valve rod is slender rod piece, length reaches 65.3mm usually, so so high coaxality and perpendicularity requirement, be difficult to reach by existing technical specifications, so core iron is prone to stuck phenomenon in sleeve pipe, make core iron slide up and down in sleeve pipe not smooth, not only easily agree with the wearing and tearing of core iron, and solenoid electric valve is broken down.
The model utility content
The purpose of this utility model is, adopts integrated type for the valve rod of prior art compressor solenoid electric valve, makes core iron easy stuck, deficiency of easily agreeing with the solenoid electric valve fault in sleeve pipe, and a kind of combined type rod member is provided.
The purpose of this utility model is achieved through the following technical solutions:
The purpose of this utility model is, a kind of combined type rod member is provided, and comprises at least 2 two rod members of rod member one and rod member, and at least one end face of described rod member one is protruding sphere, described rod member one be connected rod member two by the coaxial connection of described protruding sphere;
Connecting end with protruding sphere described rod member one described rod member two is the plane;
Connecting end with protruding sphere described rod member one described rod member two is concave spherical surface;
Described rod member one is straight-bar, and its two ends are sphere, and described rod member two is T-shaped bar, and described rod member one is connected with " one " word end of described rod member two by rod member two.
Adopt the combined type rod member of the utility model structure, because rod member is split, connection between rod member contacts connection by spherical, so being connected between rod member flexibly connects, easily centering, reduced the requirement to the coaxality of rod member own, can reduce the machining accuracy of rod member, can reduce the processing cost of rod member, and improve the overall precision of rod member.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is made explanation further:
As shown in Figure 1, combined type rod member of the present utility model comprises two rod members at least, rod member 1 and rod member 22, and the end at rod member 1 is provided with sphere 3 at least, and rod member 22 is connected by the coaxial contact of sphere 3 with one 1 of rod members.
Certainly, this combined type rod member has various deformation, can be wherein that the two ends of rod member one are sphere, and the two ends of rod member two are the plane; The two ends that can be also rod member two are the plane, can be also that an end that is connected with rod member one of rod member two is the plane, and the other end is sphere; Certainly, can be also that rod member two and connecting end rod member one are sphere.At the position that rod member one is connected with rod member two, can be sphere and being connected of plane, can be also two spheres are connected, can also be a protruding sphere be connected with a recessed sphere.
As shown in Fig. 2 and 3, combinations thereof formula rod member is applied in solenoid electric valve of the present utility model, rod member 1 is as upper valve rod 9, rod member 22 is as lower valve rod 16, and upper valve rod 9 is that two ends are the straight-bar of protruding sphere, and lower valve rod 16 preferably has the trapeze bar of the shaft shoulder, upper valve rod 9 is arranged in valve seat 8, lower valve rod is arranged in valve body 6, and an end of upper valve rod 9 is connected with core iron 10, and the other end is connected with a word end of lower valve rod.Core iron 10 is slidably arranged in the top that is positioned at valve seat 8 in sleeve pipe 13.
Certainly, lower valve rod can be also straight-bar, and has spherical end surface.
So long as upper valve rod is connected with the core iron sphere, it is just passable that lower valve rod and upper valve rod are that sphere is connected.
Solenoid electric valve of the present utility model has changed the structure of former valve rod, the assembly parts that is press-fitted by former core iron and valve rod, change into the combination of core iron 10, upper valve rod 9,16 3 parts of lower valve rod, moving up and down of core iron 10 and valve rod completed in valve seat 8 and the valve body 6 interior cooperation of three in being arranged on stainless steel sleeve pipe 13.Because being sphere, the cooperation of upper valve rod, lower valve rod and core iron coordinates, so, can relax three's coaxality requirement and the perpendicularity requirement of upper valve rod and lower valve rod and core iron.The machining accuracy of part has reduced processing cost like this along with reduction, the same performance that can be achieved requirement of the valve after assembling.
