The main application is to regulate flow and pressure. There are two kinds of valves: Positive and adjustable. There are three kinds of valves in adjustable choke valve: Needle plunger piston and hole plate. According to the Operation form, there are manual drive and hydraulic drive.
The standard: API Spec 6A and SY/5127
The characteristic: The principle of Manual drive Adjustable choke valve is hydraulic energy consumption with aerodynamics and Finite Element Analysis. Utilized the
The Pistons in the opening movement to make different sets of intermediate cross-flow area to control the flow and pressure. The high pressure fluid get into the ring-shaped space between body and corbula to change the direction. This destruction of fluid consumed energy to decrease internal erosion and noise.
Swing, Assembling and Maintaining
1, Swing: In the process of swing, we shall keep the valve stable in order to prevent valve from damage.
2, Assembling: Before installation, the pipeline should be cleaned. We should keep the valve away from heavy hammering in the process of installation.
3, Using: The valve is closed in clockwise and opened in counterclockwise; It should be strictly carried out in accordance with the relevant safety rules.
4, Maintaining: The valve should not be stored in the open air and kept away from fire. The suitable temp. Is 0° C~30° C. We should grease the main valve parts regularly.
5, The ways to possible breakdown:
1The sealing problem We should cut off the line and check it step by step. If the machine parts are broken down, we should replace and install the new ones...
2The packing problem Tightening up packing gland slightly or cutting off the line and replace packing
