Description
Technical field
The present invention relates to a kind of rod member, solenoid electric valve and compressor.
Background technique
Control valve is the crucial controlling component that carries out displacement variation in the 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, so that core iron slides up and down in sleeve pipe is not smooth, not only easily agrees with the wearing and tearing of core iron, and solenoid electric valve is broken down.
Summary of the invention
The objective of the invention is, valve rod for prior art compressor solenoid electric valve adopts integrated type, so that core iron in sleeve pipe easily stuck, easily agree with the deficiency of solenoid electric valve fault, provide a kind of solenoid electric valve core iron that makes to be difficult for stuck combined type rod member, solenoid electric valve and compressor.
The objective of the invention is to be achieved through the following technical solutions:
First purpose of the present invention 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.
Second purpose of the present invention is, a kind of solenoid electric valve is provided, comprise sleeve pipe, core iron, valve rod, valve seat and valve body, described core iron is slidingly arranged in the described sleeve pipe, described valve seat is arranged in the described sleeve pipe and is positioned at described core iron below, described valve body is positioned at described valve seat below, described valve seat and valve body are coaxial to be connected, described valve rod is comprised of upper valve rod and lower valve rod, described upper valve rod is straight-bar, its two ends are protruding sphere, described upper valve rod is arranged in the described valve seat, described lower valve rod is arranged in the described valve body, and an end of described upper valve rod is connected with the coaxial sphere of described core iron, and its other end is connected with the coaxial sphere of described lower valve rod;
Described lower valve rod is the T-shape bar, and described lower valve rod is by its " one " word end and described coaxial connection of upper valve rod sphere.
The 3rd purpose of the present invention is, a kind of compressor is provided, the solenoid electric valve that comprises the discharge capacity that changes refrigeration agent, described control valve comprises core iron, valve rod, valve seat and valve body, described valve seat and valve body are coaxial to be connected, described valve rod is comprised of upper valve rod and lower valve rod, described upper valve rod is straight-bar, its two ends are protruding sphere, described upper valve rod and core iron are arranged in the described valve seat, described lower valve rod is arranged in the described valve body, and an end of described upper valve rod is connected with the coaxial sphere of described core iron, and its other end is connected with the coaxial sphere of described lower valve rod;
Described lower valve rod is the T-shape bar, and described lower valve rod is by its " one " word end and described coaxial connection of upper valve rod sphere.
Adopt the combined type rod member of structure of the present invention, because rod member is split, connection between rod member connects by the spherical contact, so being connected between rod member flexibly connects, easily centering has been 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.
Adopt solenoid electric valve and the compressor of structure of the present invention, because rod member is sleeved in its valve seat and the valve body, connect by sphere between rod member, upper valve rod is connected by sphere with core iron, but so position between Self-adjustment upper valve rod and core iron, upper valve rod and lower valve rod, make that core iron is movable in sleeve pipe to be slided unobstructedly flexibly, core iron is difficult for stuck.

Embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is made further explanation:
As shown in Figure 1, combined type rod member of the present invention 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 one 1 of rod member 22 and rod members are connected by sphere 3 coaxial contacts.
Certainly, this combined type rod member has various deformation, wherein can be 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 also can be rod member two are the plane, also can be that an end that is connected with rod member one of rod member two is the plane, and the other end is sphere; Certainly, also can be 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, also can be two spheres are connected, can also be a protruding sphere be connected with a recessed sphere.
Shown in Fig. 2 and 3, combinations thereof formula rod member is applied in the solenoid electric valve of the present invention, 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 the valve seat 8, lower valve rod is arranged in the 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 slidingly arranged in the top that is positioned at valve seat 8 in the sleeve pipe 13.
Certainly, lower valve rod can be straight-bar also, 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.
The solenoid electric valve of said structure is used for compressor with variable displacement, at the contracting machine this solenoid electric valve is set, obtain having the compressor of split type valve rod.
Solenoid electric valve of the present invention 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 finished in valve seat 8 and the valve body 6 interior cooperations 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 cooperates, 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 the assembling.
