AI Technical Summary
The existing automatic water discharge valves are likely to cause unclean drainage during use and require manual control. They may easily cause icing or corrosion to damage the valve body after long-term use.
A new type of automatic water discharge device is designed, including valve body, sealing gasket, threaded fixed pin shaft, upper pressure plate, lower pressure plate and spring. The water pressure causes the sealing gasket and pressure plate to move downward quickly, sealing the water discharge hole to ensure that the water does not leak; after the work is completed, the spring restores the sealing gasket to its original state, and the residual water is discharged through the water discharge hole.
It realizes automatic water discharge without manpower, avoids water freezing or corrosion and damage to the valve body, and ensures the fire gun's water injection effect and drainage efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drain valves, in particular to a novel automatic drain device. Background Art
[0002] In the construction of fire water sources, there are always situations such as untimely drainage and improper use, which lead to the inability to fully use the water source. In the north, there is a freezing period. After the fire water source is used, there is a matter of draining the residual water in the pipeline above the frozen soil layer. The existing drainage devices include electronic control, manual control, semi-mechanical control, and full-automatic control. The more frequently used ones are automatic drain valves. The automatic drain valve is a valve installed in the pipeline system. The main function of the drain valve is to protect the safety of the pipeline. When the water pressure is too high, it will automatically drain the water to reduce the pressure on the pipeline. However, the above-mentioned forms all have the problem of unclean drainage and require manual control or operation. Under long-term use, it is easy to cause unclean drainage, and the valve body may be damaged by freezing or corrosion. Utility Model Content

After the work is completed, the pressure in the monitor body drops, and the pressure in the monitor body returns to a normal state. The sealing gasket of the water draining device is restored to its original state by the spring, and the residual water in the monitor body flows out of the water draining hole along its gap, thereby playing a drainage role. The water is drained automatically, and no human drainage is required, thereby preventing water from freezing or corroding and damaging the valve body. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0018] Example: Figure 1-2As shown, the utility model is a novel automatic water drain device, including a valve body 1, wherein a sealing gasket 2, a threaded fixing pin shaft 3, an upper pressing plate 4 and a lower pressing plate 5 are arranged in the valve body 1, the threaded fixing pin shaft 3 is threadedly connected to the valve body 1, the sealing gasket 2, the upper pressing plate 4 and the lower pressing plate 5 are all sleeved on the threaded fixing pin shaft 3, the sealing gasket 2 is arranged between the upper pressing plate 4 and the lower pressing plate 5, the threaded fixing pin shaft 3 is also sleeved with a spring 6, the spring 6 is arranged below the lower pressing plate 5, and a water drain hole 7 is arranged at the bottom end of the valve body 1, and the water drain hole 7 It is connected to the inside of the valve body 1. When the fire monitor enters the working water-shooting state, the water pressure causes the sealing gasket 2, the upper pressure plate 4 and the lower pressure plate 5 to move downward quickly, forming the end face of the sealing gasket 2 to seal the water leakage hole 7 on the valve body 1, so that the water in the cannon body cannot leak, ensuring the water-shooting effect of the fire monitor. After the work is completed, the pressure in the cannon body drops, and the pressure in the cannon body returns to a normal state.
