Description

Filter regulator

This article is a filter regulator that removes moisture, oil or solids present in a pressurized fluid such as compressed air and regulates the pressurized fluid to the desired pressure.

At the time of use, as shown in the reference figure showing the state of use, the article is connected to another fluid pressure machine such as a lubricator using a connecting mechanism such as a spacer.

Next, the handle is rotated to set the pressure-regulating spring to a desired pressure, and the diaphragm is used to adjust the pressing force to the valve body. When the pressure fluid is supplied from one of the pressure fluid outlet ports in this state, the pressure fluid will swirl inside the casing, and the moisture and oil contained in the pressure fluid may be scattered toward the inner wall of the casing due to the centrifugal force, and Separated from the pressurized fluid. The separated moisture and oil are transferred through the inner wall of the casing and accumulated in the lower portion of the casing to be a draining fluid.

The gas in the pressurized fluid will pass through the filter element and the solids contained in the gas will be removed. During this time, the valve body will act by the difference between the pressure of the pressure regulating spring and the pressure of the pressure fluid acting on the diaphragm, and the pressure fluid will be regulated to the desired pressure. After the excretion fluid and the solid matter are removed and the pressure is adjusted, the pressure flow system is supplied to the other fluid pressure machine via the other pressure fluid outlet introduction port.

The drain fluid accumulated in the lower portion of the casing can be identified by a transparent casing and a transparent casing protection. When the drain plug is opened, the accumulated drain fluid is discharged from the casing.

The filter pressure regulator of the design article comprises: a handle, a bonnet for fitting the handle, a main body disposed at a lower portion of the bonnet, a transparent cover fitted to the lower portion of the main body, and a transparent cover disposed outside the cover The case protector, the filter element disposed on the inner side of the cover, and the baffle disposed on the lower portion of the filter element (refer to the reference perspective view showing the names of the respective parts and the reference perspective view 2 showing the names of the respective parts).

The handle has a cylindrical shape and has a plurality of ridge portions in the axial direction on the outer circumference thereof. A pressure regulating spring (not shown) is housed inside the bonnet, and the pressure regulating spring is compressed or extended by the rotation of the handle to adjust the pressing force to the diaphragm.

The main system has an opening toward the casing, and a pressure fluid outlet introduction port that communicates with the opening is provided on both side surfaces of the main body. A flange that engages with a connection mechanism (not shown) is provided on the right and left sides of the pressure fluid outlet introduction port, and a fitting groove into which a connection mechanism (not shown) is fitted is provided above and below the pressure fluid outlet introduction port. These fitting grooves are set to have substantially the same length. A pressure gauge is provided on the other side different from the aforementioned two sides of the main body. Inside the main body, a diaphragm (not shown) and a valve body (not shown) for opening and closing a communication path (not shown) of the pressure fluid are provided in contact with the diaphragm.

A lock button is disposed on an outer circumference of the cover protector, and a drain plug is disposed at a lower end of the cover protector.

The partial cross-sectional view of the A-A line is a partial cross-sectional view of the cross section taken along line A-A of the top view.

The design of this design is characterized by the overall shape of the filter regulator.
