Zhuzhou Century Tool Co., Ltd. customizes and processes tungsten steel valve sleeves, carbide valve sleeves, tungsten steel valve cores, carbide valve cores, tungsten steel valve seats, carbide valve seats and other wear-resistant parts.
The shut-off valve is an actuator in the automation system. It is composed of a regulating valve. It receives the signal of the regulating instrument and controls the cutting, connecting or switching of the fluid in the process pipeline. It is widely used in the production of machinery industries such as petroleum, chemical industry, and metallurgy. The internal structure of the cut-off valve is usually composed of valve body, bonnet, valve core, valve ring and other components. The reliability of the cut-off valve depends to a large extent on the correct selection of its structure and materials that are fully suitable for its working conditions. and depends on operating conditions.
The oil well shut-off valve is an automatic protection cut-off valve for oil well emergency situations, and it needs to maintain good performance and operating conditions at all times. The tungsten steel material has high hardness, wear resistance, and excellent corrosion resistance. The oil well shut-off valve uses tungsten steel valve core and tungsten steel valve sleeve as working components, and its good physical properties are suitable for the working conditions of oil and gas well fields.
The dimensions of the spool we process are: φ44.4-41.3*36.62°*12.7. The tungsten steel spool of the oil well shut-off valve requires flatness of 0.005, parallelism of 0.005, end surface finish of mirror polished Ra0.2, acute angle blunt of 0.2*45°, which meets the compatibility requirements of assembly and use.
In order to meet more tungsten steel valve cores required by oilfield mechanical equipment accessories, our company provides multiple choices of tungsten steel valve seat materials. The physical parameters of commonly used tungsten steel valve sleeve materials are as follows:
1. Grain size um: 0.4～2.0
2. Cobalt content Co%: 6.0-20
3. Density g/cm3: 13.96-14.85
4. Hardness HRA: 89.5-93
5. Bending strength Mpa: 3200-4500
6. Young's modulus Gpa: 570-620
