New mud tank bottom valve

The structure of the new mud tank bottom valve is exquisite and practical. It is composed of key components such as outer tube, connecting rod, connecting tube and lead screw. The lower end of the outer tube is connected with the connecting tube, and the connecting rod is arranged inside the outer tube. The leading screw is connected with the connecting rod in the outer tube and closely cooperates with it. The connecting rod is connected with the sealing rubber at the bottom of the outer tube, and the sealing rubber is tightly fitted with the valve base. The inner side of the valve base is a tapered structure, and the inclination of the contact surface between the sealing rubber and the valve base is the same as that of the valve base. The sealing rubber is fixed by two upper and lower circular metal plates to ensure stability. In addition, the connecting part of the outer tube and the outer cylinder of the lead screw is located above the tank surface, which enhances the stability and adaptability of the valve.
  
The unique construction of the new mud tank bottom valve offers several advantages. First of all, the sealing performance of the valve has been greatly improved, ensuring reliability in extreme environments. Secondly, the optimized design of the connection between the outer tube and the outer cylinder of the lead screw improves the pressure resistance of the valve and makes it more suitable for the complex seabed working environment. In addition, the compact and efficient construction design reduces energy loss and maintenance costs.
