Intelligent electric valve

Abstract

The intelligent electric valve comprises a valve body, a mounting frame, a motor mounting box, an electric control box, an air inlet connector, a fan, a condensation pipe, a cooling box, refrigeration blocks, an oil tank, an oil outlet connector, an oil pump, a valve rod, a worm gear, a motor, a first bearing, a worm, a second bearing, an oil dripping connector, a temperature sensor, control elements and a cooling fan. A cooling mechanism is arranged, when the fan and the refrigeration blocks of the cooling mechanism work, external air can blown into the electric control box after the temperature of the external air is lowered, and the interior of the electric control box is cooled under the action of low-temperature air, so that the situation that the control elements are damaged due to the fact that the temperature is high when the intelligent electric valve is exposed outdoors in summer is avoided, and the service life of the intelligent electric valve is guaranteed beneficially. When the oil pump of a lubricating mechanism works, lubricating oil in the oil tank can be led out and dripped to the contact position of the worm gear and the worm from one end of the oil dripping connector, it is not needed to open the intelligent electric valve manually to conduct maintenance, and maintenance of the worm and the worm gear is greatly facilitated.

Description

technical field [0001] The invention relates to an electric valve, in particular to an intelligent electric valve, which belongs to the technical field of valve application. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. It has the functions of diversion, cut-off, throttling, check, diversion or overflow pressure relief. A variety of transmission methods are adopted, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electrohydraulic, pneumatic hydraulic, spur gear, bevel gear drive, etc.; can be transmitted in pressure, temperature or other forms Under the action of the sensor signal, it acts according to the predetermined requirements, or simply opens or closes without relying on the sensor signal. The size of the flow channel is used to realize its control function. With the continuo...

Problems solved by technology

[0003] Most of the existing electric control boxes for installing control components of intelligent electric valves do not contain a heat dissipation mechanism, and only rely on the flow of the air itself to dissipate heat for the control components. However, when used outdoors, in summer, the external ambient temperature is high. When the heat dissipation capacity of the device is greatly reduced, the heat in the electric control box cannot be discharged or reduced in time, and it is easy to cause damage to the control components in the electric control box, and most of the existing intelligent electric valves have little effect on the power output. The maintenance of the worm gear and worm of the mechanism accelerates the wear of the worm gear and worm, which is not conducive to ensuring the opening accuracy of the device, and has certain defects
