How does the sealing technology of OTECO MUD GATE VALVE achieve zero leakage?

In the oil industry, especially in drilling operations, preventing leakage is crucial. Jiangsu Zhonglin Oil Equipment Co., Ltd., as a professional valve supplier and factory in China, has achieved the goal of zero leakage with its excellent sealing technology, providing a strong guarantee for the safe and efficient operation of the oil industry.
1. Advanced sealing materials
OTECO MUD GATE VALVE uses high-quality sealing materials, which are carefully selected and strictly tested, and have excellent corrosion resistance, wear resistance and high temperature resistance. In harsh drilling environments, it can maintain stable performance and ensure the sealing effect of the valve.
For example, special rubber seals, with good elasticity and compression resilience, can fit the gate and valve body tightly, effectively preventing mud leakage. At the same time, this sealing material is also anti-aging and anti-fatigue, and can maintain good sealing performance in long-term use.
2. Precision processing technology
Jiangsu Zhonglin Oil Equipment Co., Ltd. has advanced processing equipment and exquisite processing technology to ensure that each component of OTECO MUD GATE VALVE has high precision and high quality.
During the manufacturing process of the valve, precision processing technology is used to ensure that the matching accuracy of the gate and the valve body reaches an extremely high level. This can make the fit between the sealing surfaces more closely and reduce the possibility of leakage. At the same time, the sealing surface is specially treated to improve its hardness and finish, and further enhance the sealing performance.
3. Unique sealing structure design
OTECO MUD GATE VALVE adopts a unique sealing structure design, which can effectively prevent mud leakage.
For example, the double sealing structure, that is, two seals are set between the gate and the valve body, one is the main seal and the other is the auxiliary seal. When the main seal has a slight leak, the auxiliary seal can play a role in time to prevent the leakage from further expanding. This double sealing structure greatly improves the sealing reliability of the valve.
In addition, the valve also adopts a pressure self-tightening sealing design. When the internal pressure of the valve increases, the pressure between the sealing surfaces will also increase, making the seal tighter. This design can adapt to different working pressures and ensure that no leakage can be achieved under various working conditions.
IV. Strict quality inspection
In order to ensure the sealing performance of OTECO MUD GATE VALVE, Jiangsu Zhonglin Oil Equipment Co., Ltd. has carried out strict quality inspection on each valve.
The inspection process includes multiple links such as appearance inspection, dimension measurement, pressure test, and sealing performance test. Only valves that have passed all inspection items can be sold from the factory. This strict quality inspection system guarantees the quality and sealing performance of the valve and provides customers with reliable products.
Jiangsu Zhonglin Oil Equipment Co., Ltd.'s OTECO MUD GATE VALVE achieves the goal of no leakage through advanced sealing materials, precise processing technology, unique sealing structure design and strict quality inspection. In oil drilling operations, this high-performance valve can effectively ensure operational safety, improve production efficiency, and make important contributions to the development of the oil industry.
