Abstract
A fluid flow regulating valve adapted to prevent the operation of the valve from violent pressure change, namely the hydraulic ram effect, in the fluid, particularly during closing and opening of the valve, the valve comprising a casing that houses a regulating plate slidably mounted within the casing. The plate has a regulating orifice having a variable fluid pass section which decreases from an end to another end of the orifice. The orifice is adapted to be aligned, through its different sections, with inlet and outlet ports provided in the casing, whereby the inlet and outlet ports communicate to each other through the orifice and the fluid flow can be regulated by those different sections of the orifice.
Claims16
A fluid flow regulating valve comprising a casing which houses a flow regulating disc plate, the casing having an inner chamber, at least one inlet port and at least one outlet port for circulation of the fluid flow through the valve, the disc plate is rotatably mounted within the inner chamber and has at least one fluid regulating orifice passing through the disc plate and defining a plurality of flow-pass sections gradually decreasing from a first end to a second end of the orifice, whereby as the disc plate rotates the valve defines a regulating mode wherein different sections of the orifice can communicate the inlet and outlet ports to each other so as to regulate the fluid flow passing therethrough, and a close mode wherein at least one portion of the disc plate out of the orifice interrupts the fluid communication between the inlet and the outlet ports, wherein the at least one portion of the disc plate out of the orifice includes a hole passing through the plate, the hole freely receiving an insert made of a low-friction sealing material, and the insert closes the fluid communication between the inlet and the outlet ports of the casing in the close mode of the valve.
A fluid flow regulating valve comprising a casing which houses a flow regulating plate, the casing having an inner chamber, at least one inlet port and at least one outlet port for the circulation of the fluid flow through the valve, the plate being slidably movably mounted within the inner chamber and having at least one fluid regulating orifice passing through the plate and defining a plurality of flow-pass sections gradually decreasing from a first end to a second end of the orifice, whereby as the plate slidably moves the valve defines a regulating mode wherein different sections of the orifice can communicate the inlet and outlet ports to each other so as to regulate the fluid flow passing therethrough, and a close mode wherein at least one portion of the plate out of the orifice interrupts the fluid communication between the inlet and the outlet ports, the at least one portion of the plate out of the orifice includes a hole passing through the plate, the hole freely receiving an insert made of a low-friction sealing material, the insert closes the fluid communication between the inlet and the outlet ports of the casing in the close mode of the valve.
