Abstract
The utility model relates to an electric valve, particularly a miniature leak-free electric valve. The utility model has the technical proposal that the miniature leak-free electric valve comprises a valve body (1), a valve core (2), a (3), a transmission gear (4), a permanent magnet inner rotor (5), a permanent magnet outer rotor (6), and a sealing sleeve (7). The permanent magnet inner rotor is connected with the transmission gear via a transmission shaft (8); the sealing sleeve is connected with a valve body in a sealing way, and the inner rotor (5) is sheathed inside the sealing sleeve; the outside of the sealing sleeve is provided with the permanent magnet outer rotor matched with the permanent magnet inner rotor; a rotary shaft (9) of the permanent magnet outer rotor is connected with an output shaft (10) of the motor. With the adoption of the utility model, when the permanent magnet outer rotor rotates, the permanent magnet inner rotor inside the sealing sleeve can rotate following the permanent magnet outer rotor, and the opening and the closure of a valve port can be realized. Because the sealing sleeve is connected with the valve body in a sealing easy, the phenomenon of leakage can be prevented. The utility model has the advantages of reasonable structure, good sealing performance, convenient operation, etc.
Description
The utility model relates to a kind of electric valve, particularly small-sized no leakage electric valve.
Existing electric valve generally is made of valve body, spool, train of reduction gears, motor etc., and the motor rotation is slowed down by train of reduction gears and improved torque, makes the spool rotation in the valve body, the open and close of control valve bore.After this electric valve uses a period of time, because leaking can appear in the wearing and tearing of seal ring, make valve damage, the material of leakage pollutes the environment.
The utility model purpose provides a kind of small-sized no leakage electric valve, prevents to leak, and solves the problems referred to above that prior art exists.
The utility model purpose is achieved by the following technical solution:
The composition of small-sized no leakage electric valve comprises valve body, spool, motor, driving gear, permanent magnetism internal rotor, permanent-magnetic outer rotor, seal sleeve, spool is connected with driving gear, place in the valve body, the permanent magnetism internal rotor is connected with driving gear by transmission shaft, seal sleeve is connected with the internal rotor cover therein with valve body is airtight, be provided with the permanent-magnetic outer rotor that is complementary with the permanent magnetism internal rotor outside seal sleeve, the rotatingshaft of permanent-magnetic outer rotor is connected with the output shaft of motor.
Adopt the utility model, the motor rotation drives permanent-magnetic outer rotor and rotates, because the interaction between magnetic pole, the p-m rotor in the seal sleeve also together rotates, and drives spool by driving gear and moves, and realizes the open and close of valve opening.Because seal sleeve is connected with valve body is airtight, prevents leakage phenomenon.
The utlity model has rational in infrastructure, good seal performance, characteristics such as easy to use.
Accompanying drawing is the utility model embodiment's a structural representation.
Below with reference to accompanying drawings, further specify the utility model by embodiment.
In an embodiment, comprise valve body (1) in the composition of the present utility model, spool (2), motor (3), driving gear (4), permanent magnetism internal rotor (5), permanent-magnetic outer rotor (6), seal sleeve (7), spool is connected with driving gear, place in the valve body, permanent magnetism internal rotor (5) is connected with driving gear by transmission shaft (8), seal sleeve (7) is connected with internal rotor (5) cover therein with valve body is airtight, be provided with the permanent-magnetic outer rotor that is complementary with permanent magnetism internal rotor (5) outside seal sleeve, the rotatingshaft of permanent-magnetic outer rotor (9) is connected with the output shaft (10) of motor.
Claims (1)
1, a kind of have a valve body (1), spool (2), motor (3), the small-sized no leakage electric valve of driving gear (4), spool is connected with driving gear, place in the valve body, also has permanent magnetism internal rotor (5) in it is characterized in that forming, permanent-magnetic outer rotor (6), seal sleeve (7), permanent magnetism internal rotor (5) is connected with driving gear by transmission shaft (8), seal sleeve is connected with internal rotor (5) cover therein with valve body is airtight, be provided with the permanent-magnetic outer rotor that is complementary with the permanent magnetism internal rotor outside seal sleeve, the rotatingshaft of permanent-magnetic outer rotor (9) is connected with the output shaft (10) of motor.
