Übersetzung für "Plattenschieber" in Englisch

The plate valve is shown in the closed position in FIGS. 1 and 2.

It is to be noted that the plate valve may be modified in various ways.

The valve is reinforced with oversize top and bottom ends to ensure proper sealing.

If the plate valve is to be opened from this position, the solenoid valve 46 is opened.

The VG model knife gate is a wafer valve designed for a wide range of industrial applications.

Accordingly, it is an object of this invention to provide a plate valve of relatively small volume and light weight.

If the plate valve is to be closed, the solenoid valve 46 is closed and the solenoid valve 48 is opened. As a result, a pressure builds up above the piston 20 while the chamber below the piston 40 is relieved of pressure.

If the plate valve is to be closed, the solenoid valve 46 is closed and the solenoid valve 48 is opened.

The flap 15 can only operate after the slider 18 has separated the filling chamber 19 from the treatment chamber 20.

Consequently, when the gate 6 is in the open position, a straight-through flow path exists for the medium flowing through the valve.

After the flap 15 has been closed, the treatment chamber 20 having emptied, the sliding plate 18 is retracted so that contents of the filling chamber 19 fall into the treatment chamber 20 and into the cutter 17.

Thus, the pressure of the medium flowing through the valve is present in the cylinder chambers 29, 30, 31, 32.

The portion of the shaft provided above the cutting unit 17 is subdivided by a slidable plate 18 forming a partition which is inclined downwardly and rearwardly. The partition 18 subdivides the interior of the charging shaft into a filling chamber 19 and a treatment chamber 20.

With the fully-automatic panel lowering device PAV, the programmable panel feeder PPS and the panel optimisation programme POP, the 4D boasts unique equipment options.

All devices including feed pump, hydraulic power pack, plate shifting device, valves and conveyors are guided by the logic in PLC, and make them work more efficiently.

These include automatic panel-lowering, automatic panel-sliding and panel optimisation to ensure full exploitation of the material.

The slide valves are respectively provided with a housing having a passage opening and with a slider plate moveable within the housing at right angles to the passage opening and which can be displaced from an open position into a closed position blocking the passage opening tightly by means of a drive mechanism.

The slide valves must meet high criteria with regard to fire safety, in particular when being used in areas where there is a risk of fire—both internally and externally.

The object forming the basis of the present invention is to provide a slide valve of the type specified at the start which meets the stringent requirements with regard to fire safety.

For that purpose, the plate slide valve has a slide plate which is formed from two parallel plates between which there are arranged two dimensionally-resilient hollow sealing rings.

So that in the event of a fire—whether caused from the inside, spreading over the line, or caused from the outside—the slide valve 1 bears up, and leaks into the atmosphere and/or in the passage are avoided as far as possible both during the fire and during extinguishing efforts, the following steps are taken according to the invention.

Those orientating devices 130 may also be provided because the slab stack PM typically becomes slightly displaced in a longitudinal direction of the slabs P as a result of the movements or vibrations inherent to the machine, so that the slab P pushed out of the stack PM by the first slab pusher 112 is not initially precisely orientated with respect to the cutter rollers 120 .

The slide valve according to claim 1, wherein said sealing profile has a height such that when said slider plate is not touching said sealing profile, said sealing profile projects perpendicularly out of said groove by a compressible dimension (x).

The invention relates to a slide valve, in particular for blocking a line conveying media, comprising a multi-part housing which has a passage opening and in which a slider plate operable by a drive component is moved longitudinally, to both sides of the slider plate, laterally to its direction of movement, a longitudinal seal respectively being disposed above the passage opening in a longitudinal groove in the housing, and this longitudinal seal respectively having an elastic sealing profile and at least one bar adjacent to the latter on one side.

In contrast, the object forming the basis of the present invention was to further develop a slide valve of the type mentioned at the start such that the service life and the sealing function of these longitudinal seals are improved, even with passage openings with large diameters.

FIG. 1 shows a slide valve 10 which is particularly suitable for blocking a line conveying media, in purification plants raw sewage or sludge, in chemistry granulate material, chemical liquids etc., in the food industry drinking liquids, cereals or flushing liquids and similar, for example, being used.
