One-way water-discharging two-way gas-guiding valve used for automatic water discharging of motor shell

Abstract

The invention relates to the field of a device used for discharging liquid from a sealed container mainly used for containing gas, in particular to a one-way water-discharging two-way gas-guiding valve used for automatic water discharging of a motor shell. The one-way water-discharging two-way gas-guiding valve used for automatic water discharging of the motor shell comprises a screw plug valve body (1), and is characterized by further comprising a rubber sealing body (2), a ball float valve element (3) and a screw plug valve bottom (4), wherein the rubber sealing body (2) is embedded in the position of a step of valve through holes (11) of the screw plug valve body (1), the screw plug valve bottom (4) is connected with the bottoms of the valve through holes (11) in a threaded sealing mode, and the ball float valve element (3) is arranged in a hollow cavity (12). The one-way water-discharging two-way gas-guiding valve used for automatic water discharging of the motor shell is simple in structure, convenient to use, good in unipolarity, and rapid in water discharging.

Description

technical field [0001] The invention relates to the field of devices for discharging liquid from an airtight container mainly containing gas, in particular to a valve for one-way water discharge and two-way air guide for automatic drainage of motor casings. Background technique [0002] At present, new energy vehicles driven by motors are gaining more and more attention. When the motor is working, heat will accumulate inside and cause temperature rise. Especially for explosion-proof motors, because the casing is sealed, there will be a large temperature difference and pressure difference in the casing when it is cold and working. The air inside the motor will produce condensed water during the alternation of cold and heat and high and low pressure. In addition, most of the on-board motors are arranged at the bottom of the chassis of the car. When the car is driving in rainy days or wading through water, if the sealing of the motor is slightly poor, there may be water inside...

AI Technical Summary

Problems solved by technology

This method has the following defects: 1. Since the sealing screw plug is arranged at the bottom of the motor casing, and the motor is located at the bottom of the chassis of the car, it is difficult to operate

2. The frequency of water discharge is not easy to control. If the frequency is too high, the work intensity will be increased. If the frequency is too low, the motor winding will be soaked in water for a long time, resulting in damage or burning of the motor. In severe cases, it will cause electric leakage accidents that endanger personal safety.
