Abstract

This invention relates to piezoelectric valves for regulating fluid flow and, more specifically, valves in which neither solenoid and servo system are included. In this particular description and claim, references are made to the flow of liquids and gases. A specific form of piezoelectric valve for regulating fluid flow consists of a casing, a cavity inside a sleeve, a disc round piece of a piezoelectric valve. and valve seat , The inlet and outlet pipes for directing fluid into and out of the cavity and are arranged on opposite sides of the disc plate parts of the valve and the apparatus for supporting the disc plate parts of the center part of the part. The periphery of the disc is co-located with the valve seat. Therefore, when the part is actuated by the input voltage, the periphery of the disc is movable and at least part of the periphery of the disc. The discs are used to control the flow of fluid between the inlet pipe and the outlet pipe.

1.Valve for shut-off and control flow to control fluid flow, valve consists of a casing, a cavity inside a casing. , The disc part of the valve made of electro-compression material and the valve seat arranged in the cavity between the 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 outer part of the center plate is positioned to work with the valve housing. Vaseline disc With applied voltage, the outer edge of the disc can move further away from the valve housing to Allow fluid to flow from the peripheral channel to the periphery of the disc Exit channel which is opposite 2. The valve according to claim 1, here is a circular disc. And the support was placed in the same center as the round plate. 3. Valve according to claim 1 Here, a metal base will Protruding outward from the piezoelectric layer to form It is the peripheral boundary independent of piezoelectric. 4. Valve according to the claim. 1 consists of main electrodes with Sensing electrodes separated from the main electrode. 5. Valves according to claim 1 Here, a metal base is made of Made up of iron / nickel alloys 6. Valves according to claim 1 Here, a metal base will Makes thermal compatibility relative to the layer of material Pieso Electric 7. Valves according to claim 1 here, the thickness of each layer. The piavo electric valve disc guide layer has been selected. The center axis of the disc does not match the surface between the layers. Adjoining 8. 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 arranged 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, 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. Valves according to claim 8 Here, the disc is a round shape and the support is arranged in the same concentricity as the disc 1. 1. The valve according to claim 8 consists of the main electrode with The sensory electrode is separated from the main electrode 1. 2. Valve according to claim 8, here the thickness of the layer but Each layer of the piavo electronic valva disc has passed Chosen by the heart The center of the disc does not match the joint surface. Between adjacent floors 1 3.Valve according to claim 8, here the valve seat consists of a flexible binder seal that is flexible according to 1. 4.Valve for shut-off and control flow to control fluid flow, valve consists of a casing, cavity inside a casing, a circular disc 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.
