Description

Motor that valve accuse water gauge was used

Technical Field

The utility model belongs to the technical field of the water gauge is made and specifically relates to indicate a motor that valve accuse water gauge was used.

Background

With the urbanization process of the society and the increase of labor cost, the traditional manual meter reading is slowly replaced by remote meter reading, and furthermore, the valve can be remotely opened and closed according to the use condition of a user, so that the management is convenient. The water meter used here is a valve-controlled water meter, which adopts a water meter module to control a motor actuator, and the motor controls the rotation of a ball valve through a gear set, thereby opening/closing the valve. The valve control water meter is mainly installed in a ground well or a very humid place, the motor is a core part of the valve control water meter, the motor does not have the requirement on sealing performance, parts in the motor can rust gradually to cause damage of the motor when the valve control water meter works in an environment with high humidity for a long time, or the motor and a gear in the gearbox can be installed in a plastic sealing shell due to the production cost, but the plastic can absorb water, so that moisture can not be prevented, and the motor can be damaged due to rusting, so that the service life of the motor is greatly shortened.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

An object of the utility model is to provide a motor that valve accuse water gauge was used strengthens the sealing performance of self through improving its structure, is favorable to postponing its rusty time, and then prolongs the life of motor. In order to achieve the above purpose, the utility model adopts the following technical scheme:

(II) technical scheme

The utility model provides a motor that valve accuse water gauge was used, includes motor body, motor body's head parcel has the metal-back, the metal-back inside callipers is equipped with the sealing washer, the sealing washer cover is established motor body's epaxial, motor body's afterbody parcel has the plastic casing, the plastic casing surface scribbles the waterproof glue.

Further, the sealing washer center is equipped with the bell mouth, the bell mouth upper end is little, the lower extreme is big, the bell mouth upper end contacts with motor body's axle.

Further, an arc-shaped groove is formed in the upper end of the sealing ring, and a reversing piece for extruding the arc-shaped groove is concavely arranged in the middle of the metal shell.

(III) advantageous effects

Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, the utility model discloses a two parts wrap up alone around the motor, can strengthen its self sealing performance, are favorable to postponing its rusty time, and then prolong the life of motor.

Drawings

Fig. 1 is a cross-sectional view of the present invention.

The reference numbers illustrate:

1. motor body 2, metal shell 21, back-off component 3, sealing washer

31. Tapered hole 32, arc-shaped groove 4 and plastic shell

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, a motor for a valve-controlled water meter comprises a motor body 1, wherein a metal shell 2 wraps the head of the motor body 1, the metal shell 2 can effectively prevent water and moisture, a sealing ring 3 is clamped in the metal shell 2, the sealing ring 3 is sleeved on a shaft of the motor body 1, the sealing ring 3 is slightly contacted with the shaft of the motor body 1, so that the water and moisture are prevented, and the influence on the rotation of a motor shaft is small, because the valve-controlled water meter generally works for 2-4 times per month and 20 seconds each time, the influence on short-term work is small, the valve-controlled water meter can be worn and has poor water and moisture preventing effects, a plastic shell 4 wraps the tail of the motor body 1, and waterproof glue is coated on the surface of the plastic shell 4.

In order to reduce the influence of the sealing ring 3 on the rotation of the motor shaft, the center of the sealing ring 3 is provided with a tapered hole 31, the upper end of the tapered hole 31 is small, the lower end of the tapered hole 31 is large, and the upper end of the tapered hole 31 is in contact with the shaft of the motor body 1.

In order to make the sealing ring 3 clamped more firmly, the upper end of the sealing ring 3 is provided with an arc-shaped groove 32, the middle of the metal shell 2 is concavely provided with a reverse fastener 21 for extruding the arc-shaped groove 32, and the arc-shaped groove 32 is tightly pressed through the reverse fastener 21 so as to make the sealing ring 3 tightly attached to the motor body 1.

The utility model discloses a two parts wrap up alone around the motor, can strengthen its self sealing performance, are favorable to postponing its rusty time, and then prolong the life of motor.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
