Abstract

The utility model discloses a water-proof electric valve which comprises a valve body, a valve shaft, a valve core, a valve body connector and a motor box, and is characterized in that the motor box and the valve are connected through a dormant bolt, a water-proof sealing washer is arranged in the middle to isolate the motor box and the valve; the valve body is provided with a water outlet to prevent in the pipe diameter from being leaked or penetrating into the motor box after the electric valve works for a long time; the valve shaft is provided with three O-shaped seal rings, wherein two O-shaped seal rings are arranged below the water outlet and one O-shaped seal ring is arranged above the water outlet so as to prevent mist in external environment from entering the motor box and simultaneously prevent the water in the pipe diameter from entering the motor box; and at a joint between valve bodies is provided with one O-shaped waterproof gasket so as to prevent the water in the pipe diameter from penetrating outside the valve.

Description

A kind of waterproof type electric valve
(1) technical field
The utility model relates to a kind of electric valve, particularly relates to a kind of waterproof type electric valve that is applied in intellectual water meter or the intelligent calorimeter.
(2) background technique
At present, valve used in intellectual water meter, intelligent calorimeter has adopted electric valve, and so-called electric valve briefly is exactly to utilize the electric actuator control valve, realizes the Kai Heguan of valve.Electric actuator generally adopts micromachine.Electric valve can be divided into two-part up and down, and upper half part is an electric actuator, and lower half portion is a valve.Because electric valve can not comprehensively detect the quality of its sealability when dispatching from the factory, therefore there is following hidden danger in actual applications: though electric valve has been realized the isolation of electric valve and external environment condition (being water, the mist in the external environment condition) on structural design, but, electric valve is in long running, shipwreck in the caliber is exempted to leak in the electric actuator, thereby cause electronic do-part to damage, equipment enters state of paralysis, the maintain and replace frequency is higher, has increased production and operation cost.
A kind of waterproof type electric valve of my company's utility model patent has thoroughly solved above problem, not only guarantee the isolation of electric valve and external environment condition (water in the external environment condition, mist), also prevented the water in the pipeline because the electric valve long-play is penetrated into electronic do-part, thereby prolonged the working life of electric valve, reduce the maintain and replace frequency, reduce the production and operation cost.
(3) model utility content
The technical barrier that the utility model solved is: at existing electric valve water-proof performance defect of bad, provide a kind of waterproof type electric valve.
The technical solution of the utility model is:
A kind of waterproof type electric valve contains valve body, valve shaft, spool, valve body joint, motor case, and it is characterized in that: the motor case is connected through countersunk screw with valve, and the centre has a waterproof sealing packing ring that motor case and valve are isolated; On valve body, be provided with water outlet, prevent that the leakage of water contingency or the electric valve water in the caliber behind long-play in the caliber from can leak in the motor case; Be provided with three road O RunddichtringOs on valve shaft, wherein twice O RunddichtringO is positioned at the water outlet below, and one O RunddichtringO is positioned at the water outlet top, prevents that the water smoke in the external environment condition from entering in the motor case, prevented that also the water in the caliber from entering in the motor case simultaneously; Be provided with an O type waterproof washer at valve body and valve body joint, prevent that seepage in the caliber is to the valve outside.
The beneficial effects of the utility model:
(1) a kind of waterproof type electric valve of the utility model has thoroughly solved the bad shortcoming of existing electric valve water proofing property, has reduced the frequency of maintain and replace, has reduced the cost of production and operation.
(2) a kind of waterproof type electric valve of the utility model is simple in structure, is easy to realize, is easy to produce in batches.
(4) description of drawings
Accompanying drawing 1 is a kind of waterproof type electric valve of the utility model structural representation
(5) embodiment
Below in conjunction with embodiment the technical solution of the utility model is described in further detail.
As shown in Figure 1: a kind of waterproof type electric valve, contain valve body (7), valve shaft (5), spool (6), valve body joint (10), motor case (1), it is characterized in that: the motor case is connected through countersunk screw (2) with valve, and the centre has a waterproof sealing packing ring (8) that motor case and valve are isolated; On valve body, be provided with water outlet (4), prevent that the leakage of water contingency or the electric valve water in the caliber behind long-play in the caliber from can leak in the motor case; Be provided with an O RunddichtringO (3) in valve shaft water outlet (4) top, prevent that the water smoke in the external environment condition from entering in the motor case, prevented that also the water in the caliber from entering in the motor case simultaneously; Be provided with an O type waterproof washer (9) at valve body and valve body joint, prevent that seepage in the caliber is to the valve outside.
On spool (6) top end, be provided with protruding strong cooperation of a groove and valve shaft (5) lower end,, be provided with an osculum at position, valve body upper end for the water that prevents pressure enters in the motor case (1) by seal ring; The utility model valve shaft place is provided with three road O RunddichtringOs, and wherein twice O RunddichtringO is positioned at the water outlet below, and one O RunddichtringO is positioned at the water outlet top.The O RunddichtringO (3) that is arranged in water outlet top is that the water smoke for external environment condition enters into the motor case, has prevented that also the water in the caliber from entering in the motor case simultaneously.Locate to be provided with an O type waterproof washer (9) at valve body (7) and valve body joint (10), prevent that seepage in the caliber is to the valve outside.Above structural design has guaranteed the water proofing property of electric valve fully.
Because the utility model is mainly used in intellectual water meter, the intelligent calorimeter, and these two kinds of instrument require all than higher the water proofing property of electric valve, therefore in order to improve the water proofing property of electric valve, water outlet (4), O RunddichtringO (3), O type waterproof washer (9) have comprehensively guaranteed the water proofing property of electric valve in a kind of waterproof type electric valve of the utility model structural design.

Claims (1)

1. a waterproof type electric valve contains valve body, valve shaft, spool, valve body joint, motor case, and it is characterized in that: the motor case is connected through countersunk screw with valve, and the centre has a waterproof sealing packing ring that motor case and valve are isolated; On valve body, be provided with water outlet, prevent that the leakage of water contingency or the electric valve water in the caliber behind long-play in the caliber from can leak in the motor case; Be provided with three road O RunddichtringOs on valve shaft, wherein twice O RunddichtringO is positioned at the water outlet below, and one O RunddichtringO is positioned at the water outlet top, prevents that the water smoke in the external environment condition from entering in the motor case, prevented that also the water in the caliber from entering in the motor case simultaneously; Be provided with an O type waterproof washer at valve body and valve body joint, prevent that seepage in the caliber is to the valve outside.
