The function of this type of valve is to allow the free flow of fluid in one direction, while limiting its reverse flow, when the pressure of the fluid through the system, open the valve, any reverse flow, will close the valve, the completion of the closure, depend on the weight of the check mechanism or rely on the reverse pressure…
1. Characteristics of various types of valves
(1) Check Valves —– Swing Type, Lift Type, tilting Disc, dualplate, and Foot Valves.
The function of this kind of valve is to allow the free flow of fluid in one direction, and limit its reverse flow, when the pressure of fluid through the system, open the valve, any reverse flow of fluid, will close the valve, the completion of the closure, is to rely on the weight of the check mechanism or rely on the back pressure, or rely on the spring or combination of several.
(2) Globe stop-check Valves, Inc.
The CHECK VALVE IS SIMILAR TO THE LIFTING TYPE CHECK VALVE IN ITEM 3.3, BUT WITH THE STEM AND HAND TRANSMISSION (OR OTHER auxiliary OPERATING device) AS the fluid shut off and CHECK, THE CHECK valve CAN not be opened by any mechanical transmission, only by the upstream fluid pressure to lift the valve, away from the seat face.
(3) Plug Valves, Inc.
This valve by inserted into the body of the valve plug (door), to have a taper in the middle of the slot plug of the name, simple structure of old type valve, the RPM is only 90 degrees, the plug (door) LiuKou can be of any size and shape of porous type can also be made to match three or four pipeline connection, and can have different flow combination. Generally used for full opening or full closing, not for THROttling use (unless the opening is special diamond shape and treated).
(4) Ball valve (ball valve)
Ball valve is modified by plug valve, to replace the plunger with the ball plug, to control the liquid, plug (door) channel cross-sectional area, and with the pipeline diameter is the same, the fluid as a straight line through the valve body, and suction has a small pressure drop. Now generally use PTEE, EPDM and other materials, for the seat, therefore, the bubble sealing is good. And modified for fire protection and anti-static safety design, is used by ***, but because the valve seat is PTFE material, its use temperature is generally limited to 250 degrees below.
(5) Butterfly Valves, Valves
The valve structure, it is according to the principle of pipe in pull, the flow control element is an Angle plate (door), the material can be metal or metal plastic, fluoro lung on the outer package, etc.), disc fixed axis on heart, and can rotate mandrel to control opening and closing (open, closed only 90 degrees of rotation), seat for materials such as metal, rubber, fluorine, and fixed in the valve body wall, The valve is simple in structure and its body is wafer type. It is light in weight and does not take up space for throttling and opening and closing. Especially for large flow control (not for small flow).
2009 is destined to be an extraordinary year for the pump and valve industry after the 2008 global financial crisis, ushered in another year-end season.
National New Deal, another 4 trillion investment, the development of seven new industries, including new energy, new materials, information industry, new medicine, biological breeding, energy conservation and environmental protection, electric vehicles, a new round of economic stimulus program began, only such as the funds in place, the project started.
As a part of the pump and valve industry in 2008 tasted the beauty of 4 trillion investment, in 2009, the pump and valve industry no lack of “carp jump dragon gate” potential, 2010, perhaps there will be more expectations.
