TH15031A - Systems for controlling fluid flow - Google Patents

Abstract

The invention involved a piezoelectric valve for fluid flow control and, more specifically, a valve which had neither a solenoid nor a servo system. In specific detail and this claim, refer to flows that are composed of liquids and gases. The autoclave design of a piezoelectric valve for fluid flow control consists of a casing, a cavity inside a casing, a circular disc element of a piezoelectric valve. And valve seat , Inlet and outlet pipelines to guide fluid in and out of the cavity and are placed on the opposite side of the disc part of the valve and device for supporting the disc at the center of the part. Therefore, while cocking the part with an input voltage, the outer portion of the disc is mobile and at least part of the periphery of the disc. A disc is used to control the flow of fluid between the inlet and the outlet pipe.

Valve for shut-off and flow control to control fluid flow, valve consists of a casing, cavity inside a casing, a spherical part of a valve made of electro-compression material and a valve seat positioned. Inside the cavity between Inlet and outlet port, the valve housing has signs all around. The outside relative to the signal surrounding the outer part of the component. Valve disc, circular disc part of the valve assembly. With a metal base with a sealed piezoelectric layer Adjacent to at least one of its surfaces, the inlet and outlet through which fluid is drawn in and out of the cavity and Place it on the side opposite the part that is The disc of the valve, and equipment for supporting the The disc of the valve at the center of the component where the The periphery of the disc positioned to work with the valve housing, therefore, amidst the actuation of the The disc of the valve with applied voltage, will cause the outer edge of the disc to move away from the valve seat to Allow fluid from the inlet along the periphery of the disc to The outlet, which is on the opposite side, is called the base that is The metal protrudes outward from the piezoelectric layer. To form the peripheral boundary independent of the piezoelectric, encompassing the peripheral boundary independent of the pia. Such a solenoid is sealed against the valve housing when the valve closes. 9. The valve according to claim 8 consists of a control device. Feedback for opening displacement control And so is Fluid flow adjustment 1 0.
