Product introduction:STRUCTURAL FEATURES
1. In the valve's opening/closing process, there is no contact between the sealing surfaces of the valve body and the vane, so the sealing surfaces suffer neither friction nor wear, contributing to the valve's long service life and small opening/ closing torque;
2. For the valve's maintenance, there is no need to remove the valve from the pipeline but just remove its bottom cover to replace the vane pair, thus very easy for the maintenance;
3. The valve's body and plug are reduced-bore or full-bore so that the medium can flow through the valve without any flow resistance, and it's also possible to clean the pipeline with pigging to overcome the shortcomings of the reduced bore valve;
4. The cavity of the full-bore/reduced-bore general valve is plated with hard chrome and the sealing area is hard and smooth;
5. The elastic seal on the vane is made of the fluorine rubber and molded and formed in a groove of the vane surface. The fireproof metal-to-metal seal is used as the backing of the elastic seal;
6. The valve is provided with an automatic bleed device [optional] which can prevent the abnormal pressure rise of the valve cavity and check the valve's effect after the valve is completely closed;
7. The valve's opening/closing indicator is in sync with the opening/closing position and can accurately display the gear drive full-bore general valve's opening/dosing status.
FUNCTION AND APPLICABILITY ANALYSIS OF DOUBLE BREAK AND BLEED VALVE (FULL BORE]
Introduce a double block and bleed valve's structure and working principle.The valve is superior to common gate and ball valves in terms of its sealing performance and service life.The valve has the functions of being fireproof, on-line maintenance, double block and bleed, cavity pressure relief, internal leak detection and others. Illustrate the double block and bleed valve's functions and applications in the oil and gas storage and transportation systems in combination with examples, which has opened new development potential for process design of oil and gas storage and transportation systems and solved many problems encountered in pipeline design. It has not only optimized the pipeline design and improved the product quality but also saved the pipeline operation costs.
