AI Technical Summary
The existing bottom valves used in mining equipment cannot ensure sealing only by the sealing ring in the external structure. The entry of external water sources will affect the sealing and normal operation of the valve. The backflow of water and the entry of mud and sand impurities will cause the valve to fail or be damaged.
The double sealing fastening design is adopted. By using the first sealing gasket and the second sealing gasket at the connection between the valve body and the valve seat, combined with the threaded connection of the inner bolt, inner nut, outer bolt and outer nut, a double flange connection is achieved to enhance the sealing and connection strength.
It provides double waterproof protection, reduces the risk of leakage, increases the sealing reliability and connection strength of the valve body and valve seat, and ensures the stable operation of the valve in the harsh environment of the mine.

TECHNICAL FIELD
[0001] The utility model relates to bottom valve technical field, especially in bottom valve with surface waterproof structure for mine equipment. BACKGROUND
[0002] The bottom valve for mine equipment is also called mine bottom valve, and it is a valve used in mines, underground engineering, drainage systems or other liquid conveying systems. It is mainly used for controlling the direction of water flow and preventing backflow. It is usually installed at the bottom of a mine, a drainage pipeline or a water pool. The bottom valve for mine equipment is an important liquid control device in the mining industry. It not only ensures the rationality of the water flow direction, but also improves the safety and working efficiency of the system.
[0003] In the patent with the announcement number CN 220668481 U, a bottom valve with surface waterproof structure for mine equipment is disclosed. The bottom valve with surface waterproof structure for mine equipment is provided with a pressure sleeve, a sealing ring, a retaining ring, a water inlet, a check pin, a check pin, a gland and a hole. The pressure sleeve plays a protective role. The O-shaped sealing ring can play a sealing role to prevent water leakage. The retaining ring can protect the O-shaped sealing ring. The water inlet allows water to flow into the valve body. The check pin and the check pin play a fastening role. The gland plays a protective role. Water can flow in through the hole. The water flowing in through the hole passes through the packing layer. The packing layer can increase the contact area. The valve seat plays a supporting role. The top rod extends into the valve body. The top rod can hold the valve core. The valve core can control the flow of water. This design has good waterproof effect and can prevent water backflow.
[0004] Although the valve core can control the flow of water in the above-mentioned technology, it is difficult to ensure the sealing property of the external structure only relying on the sealing ring. If the external water source enters the system through the valve, it will affect the sealing property and normal operation of the valve. Water backflow and sediment impurities entering the valve body will cause the failure or damage of the valve. Therefore, this technology has certain limitations, and innovation is needed in this technology. UTILITY MODEL CONTENTS
