Description

Integral diaphragm valve using motor

The present invention relates to an integrated diaphragm valve using a motor, and relates to an integrated diaphragm valve using a motor that rotates a cam part through rotation of a motor, and a piston is lifted by the rotation of the cam part to control a fluid flow of the flow path plate.

In general, the flow control valve for controlling the flow rate is operated through a pressure difference, and among the many flow valves operated by the pressure difference, US Pat. No. 2,980,385 to the following prior patents E.J. US No. 3,493,008 by P.J Scaglione; Patent application US No. 08 / 545,890. Hunter's U.S. Patent No. 2,980,385 discloses a valve having an almost hemispherical yieldable membrane, even when the wall of the valve is relatively thick so that the pressure is considerably high in the recess of the valve. It is not locked at this flow oil discharge port. On the other hand, excessive wall thickness prevents the valve from reacting to small pressure differentials, so that the valve may be permanently closed or only very small flows may be released without releasing the required flow at the slight opening of the valve. have.

The US Patent No. 3,493,008 to Scaglione discloses a valve having a disk active cup and a valve active element composed of a metallic, welded, flexible bellow. Metallic flexible bellows wall easily reacts to the pressure difference on both sides of the wall and distorts when the internal pressure is higher than the external pressure, which requires the design of a bellows with a more resistant wall during high pressure operation and thus sensitivity to minor pressure changes. Low valve is obtained.

On the other hand, the disc cup is basically rigid and the sealing device of the disc cup loses efficiency with the valve seat when the flow rate in the conduit carries impurities. In addition, substantial losses of the load due to the valve structure are created.

Most valves in the prior art operated by pressure differentials have a complicated structure with considerable load loss, and have very little flexibility with regard to hydraulic pressure in conduits. In other words, these valves are designed to regulate the flow rate within a smaller range of pressure, which results in loss of efficiency for significant pressure changes in the conduit.

Perez's U.S. Patent Application No.08 / 545,890 discloses a differential valve that is sensitive to slight pressure changes and resistant to significant operating pressures, which allows for a very simple design with few components. This differential valve shows a rigid valve body having a flow inlet opening and a flow inlet outlet which is located in a manner substantially intersecting with the inlet opening. The valve body has a main cavity between the flow inlet and the discharge outlet, and a valve seat at the boundary between the main cavity and the flow inlet. In addition, the valve body is provided with a conduit for the control flow rate flow outlet connected to the control flow rate transmission means of the valve. The valve has an elastomeric body located inside the valve's main cavity, which is hollow and one of its shaft ends is open and a central opening is provided at the other end.

The central opening transmits a control flow inlet to the cavity, which has the same properties as the flow rate of the network in which the valve is operating.

Although this last kind of valve is useful and simple in design, it is not possible to use a control flow rate other than that of the network, which is essential in automatic control systems or in devices where a large amount of control flow is to be controlled via fine signals. . The present invention has several components disclosed in U.S. Patent Application No. 08 / 545,890, but differs from prior art valves by having inlet means for controlled flow rates that can be independent of the main flow of the network. It is possible to obtain operating dynamics for valves entirely different from.

However, these valves have a problem that the manufacturing cost is high, there is a problem that the control of the flow rate is difficult.

The present invention is to provide a one-piece diaphragm valve using a motor to rotate the cam portion through the rotation of the motor, the piston is elevated by the rotation of the cam portion to control the fluid flow of the flow path plate.
