Abstract
The utility model relates to a magnetic rotor structure of a solenoid valve, which comprises a stopper structure, screw nails of the stopper, a screw thread screw rod, a magnet, a valve needle and a spring of the valve needle, wherein, the valve needle is arranged on the lower part of the screw thread screw rod by the spring of the valve needle and a sleeve of the valve needle, an intermediate body is arranged between the inner ends of the spring of the valve needle and the screw thread screw rod, and the intermediate body is a mushroom-shaped gasket and can also be a flat gasket. The upper part of the spring of the valve needle and the screw thread screw rod are provided with gas-pressure balance holes which penetrate through the flat gasket and the screw thread screw rod and can also be provided with a globe body. The utility model has the advantages of reasonable structure, convenient operation, long service life, etc., and the product performance can be increased obviously.
Description
Technical field
The utility model relates to the magnet rotor structure of a kind of electric expansion valve or similar valve body, belong to a kind of rotor structure of solenoid valve.
Background technique
In the prior art, the magnet rotor structure of electric expansion valve or similar valve body includes stopper structure, stopper screw, threaded screw rod, magnet, needle and needle spring etc.Be inlaid with metallic rod on the stopper structure, adopt injection moulding or molding bonded, and threaded screw rod adopts metal machining or molding and forming, and adopt injection moulding or bonding process to be connected with porcelain body, needle is placed in the bottom of threaded screw rod by the needle spring of end, needle and needle spring can produce rotation in the bottom of threaded screw rod in the using process, be easy to generate bigger surface friction drag each other, this not only can reduce the performance of valve product, and the working life of having reduced valve owing to the existence of surface friction drag.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of magnet rotor structure that can reduce the solenoid valve of surface friction drag between needle and the threaded screw rod, it includes stopper structure, the stopper screw, threaded screw rod, magnet, needle and needle spring, described needle is placed in the bottom of threaded screw rod by needle spring and needle cover, and the inner end of its needle spring and threaded screw rod is every being equipped with an intermediate.
Described intermediate is a mushroom-like pad.
Described intermediate also can be a flat gasket, and the top threaded screw rod of needle spring is provided with the air equalizer opening that runs through flat gasket and threaded screw rod.
Described intermediate can also be a spheroid.
The utility model compared with prior art has rational in infrastructurely, easy to use, can obviously improve the performance of valve product, prolongs the characteristics such as working life of valve.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another example structure schematic representation of the present utility model.
Fig. 3 is another example structure schematic representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, magnet rotor of the present utility model includes stopper structure 1, stopper screw 2, threaded screw rod 3, magnet 4, needle 8, needle spring 6.Be inlaid with the technology bar at stopper structure 1, it adopts injection moulding or molding bonded.Threaded screw rod 3 adopts metal machining or molding and forming, and adopts injection moulding or bonding process to be connected with magnet 4.Needle 8 is installed in the bottom intermediate cavity of threaded screw rod 3, and needle spring 6 and the roof pressure inner end in intermediate cavity is arranged on it.Also has needle cover 7 on the needle 8, this needle cover 7 and threaded screw rod 3 interference fit.Be placed with a mushroom-like pad 5 on the top of needle spring 6.The top of this mushroom-like pad is semiglobe, and it contacts with the inner planar point of top threaded screw rod intermediate cavity; The bottom is a cylindrical end, and it can be enclosed within the endoporus of needle spring 6.Described mushroom-like pad 5 can adopt metallic material machining or molding and forming.Owing to be placed with mushroom-like pad 5 on the top of needle spring 6, it can reduce needle 8 and needle spring 6 in use because of producing bigger surface friction drag between rotation and the threaded screw rod 3.
Figure 2 shows that another embodiment of the present utility model, it just replaces mushroom-like pad 5 with a flat gasket 9, offer the air equalizer opening 10 that runs through flat gasket 9 and threaded screw rod 3 in addition in the centre of threaded screw rod 3, flat gasket 9 can play and 5 effects identical, that reduce surface friction drag of mushroom-like pad between needle spring 7 and threaded screw rod 3.And air equalizer opening 10 can play pressure balanced effect, is used to prevent form between needle 8 and the threaded screw rod 3 high-pressure gasbag and uses.
Figure 3 shows that another example structure schematic representation of the present utility model, it replaces above-mentioned mushroom-like pad 5 or flat gasket 9 with a spheroid 11, it play a part with above-mentioned two embodiments in identical, can reduce surface friction drag between needle spring 6 and the threaded screw rod 3.
Because said other structure content of the utility model is known technology, thereby those skilled in the art just can implement the present patent application technology easily after understanding the technology contents of present patent application, thereby other structure content of solenoid valve is not done more detailed introduction.
