Selection 1. Inlet and outlet diameters of strainers In principle, the inlet and outlet diameter of the strainer should not be smaller than the inlet diameter of the matching pump, and generally consistent...
Because of the functions of sealing elements on the valve channel, such as cutting and connecting, adjusting and distributing, separating and mixing media, the sealing surface is often corroded, eroded,...
1. Overview Valves are important pipeline pressure components in petrochemical plants, with a wide range of quantities and types, among which check valves are one of the most commonly used valves. In...
Butterfly valves are commonly used valves in industrial water systems, and have become commonly used valves in pipelines due to their small sizes and high cost-effectiveness. Although butterfly valves...
It is inevitable to involve the selection of check valves when designing pipelines for petrochemical plants due to the wide variety of check valves. The reasonable selection of check valves not only affects...
Gate valves and butterfly valves can open or close pipelines. Of course, there are still methods in the selection process of butterfly valves and gate valves. To reduce the depth of soil cover in the...
The valve that automatically discharges condensate and prevents steam from passing through is called a steam trap valve. A steam trap valve is an automatic regulating valve that can automatically discharge...
With the construction and expansion of large-scale oil refining and petrochemical projects such as ethylene, the selection of fast closing, low-pressure loss, and noise-resistant check valves are required...
1. The Sealing Structure of the Valve Stem The valve stem seal adopts three O-ring knots. The third O-ring can reduce the pressure at the gland and also enable the replacement of the upper two sealing...
Coal water slurry is a new type of clean liquid fuel and an important part of clean coal technology. Since its inception, it has been favored for its many advantages such as oil replacement, energy saving,...
