Technical field

The utility model relates to a kind of water Proportional valve assembly.

Background technique

Existing water Proportional valve assembly comprises valve body, spool and drives the positions such as solenoid valve of valve core rotation, is provided with water intake and water outlet on valve body, spool belt spool hole.Its structure more complicated, volume is bigger, and valve core rotation has the dead angle, inconvenient operation

The model utility content

The utility model is to overcome the deficiencies in the prior art and provide a kind of simple in structure, and volume is small and exquisite, and spool can 360 degree rotations, a kind of water Proportional valve assembly at no stop dead angle.

In order to achieve the above object, the utility model is achieved in that it is a kind of water Proportional valve assembly, comprises valve body, is provided with flow channel in valve body, is provided with the water intake and the water outlet that are communicated with flow channel on valve body; The spool and an end and the fixing mandrel of spool that also comprise the belt spool hole that is located at the can regulate water-outlet quantity size in the flow channel; It is characterized in that: on spool, be provided with the spool aperture; Also comprise the shell of fixedlying connected with valve body, be located in the shell and rotating internal gear and be installed in motor on the shell, between shell and valve body, be provided with seal ring, the other end of mandrel is fixed on the internal gear, is provided with seal ring between mandrel and the shell; Also comprise the external gear that is located in the internal gear, internal gear and external gear engagement, the driven by motor external gear rotates; Also comprise and be located in the flow channel and be positioned at the current inductive component of water inlet and be fixed on the outer Hall components and parts of valve body; Also comprise and be located at the circuit board in the shell and be located at permanent magnet on the internal gear.

Be provided with the location end cap on described shell, motor is installed in positioning end and covers.

Described motor is a synchronous machine.

The utility model advantage compared with prior art is, simple in structure, volume is small and exquisite, and water flow is big, and spool can 360 degree rotations, no stop dead angle; When automatically controlled breaking down, can mechanical damage other element.

Embodiment

Below in conjunction with drawings and Examples the utility model is done further detailed description:

Shown in Fig. 1 to 7, it is a kind of water Proportional valve assembly, comprises valve body 2, is provided with flow channel 23 in valve body, is provided with the water intake 22 and the water outlet 21 that communicate with flow channel on valve body; The spool 6 and an end and the fixing mandrel 10 of spool that also comprise the belt spool hole 62 that is located at the can regulate water outlet water-outlet quantity size in the flow channel; Characteristics of the present utility model are: be provided with spool aperture 61 on spool 6; Also comprise the shell 3 of fixedlying connected with valve body 2, be located in the shell and rotating internal gear 11 and be installed in motor 1 on the shell, shell is by being bolted on the valve body, between shell and valve body 2, be provided with seal ring 5, the other end of mandrel 10 is fixed on the internal gear 11, be provided with seal ring 7 between mandrel and the shell 3, the sealing circle is " O " RunddichtringO; Also comprise the external gear 12 that is located in the internal gear, internal gear and external gear engagement, the driven by motor external gear rotates, and external gear is fixed in the rotating shaft 13 of motor 1; Also comprise and be located in the flow channel 23 and be positioned at the current inductive component 9 of water inlet and be fixed on the outer Hall components and parts 8 of valve body; Also comprise and be located at the circuit board 14 in the shell and be located at permanent magnet 15 on the internal gear.In the present embodiment, be provided with location end cap 4 on shell 3, motor 1 is installed in positioning end and covers, and current sense group body spare comprises water wheels; Motor 1 is a synchronous machine.

During work, when current when the water intake 22, current inductive component 9 is sensed water-flow signal and this signal is issued electronic management system on the circuit board 14, starts water heater; When water heater is operated at full capacity and water-exit temperature when also not reaching setting temperature, motor 1 counterclockwise rotation, external gear 12 also rotates thereupon, internal gear 11 also rotates under the drive of external gear, the spool bore 62 of spool 6 misplaces with the flow channel 23 of valve body, the aperture of flow channel is diminished, thereby the flow velocity of water is reduced, when being reduced to water-exit temperature when reaching the temperature of setting, motor shuts down.Otherwise, when water heater during with the load operation of minimum, and when water-exit temperature also is higher than setting temperature, motor clockwise rotates, make spool bore 62 over against flow channel, it is big that the aperture of flow channel becomes, thereby the flow velocity of water is increased, when increasing to water-exit temperature and reach the temperature of setting, motor shuts down.When the permanent magnet on the internal gear 11 15 be rotated the position be in spool bore 62 in flow channel 23 largest passages position or smallest passage position promptly over against spool aperture 61, permanent magnet is respectively over against Hall components and parts 8, in these two positions, the electronic management system on the circuit board 14 sends instruction shuts down motor.
