Abstract
The utility model relates to a hydraulic pressing device of a pressure container flange end cover. A filter cylinder of a magnetic grid type high-viscosity oil liquid filter is full of an oil liquid and it is necessary to frequently open an upper cover. The upper cover is connected and fastened with the filter cylinder by a bolt (2). The upper cover (1) is jacked up and closed by a hydraulic cylinder (4) arranged in the center of the filter cylinder. After the upper cover rests, the upper cover is trained by the hydraulic cylinder and closed. The telescoping of the hydraulic cylinder is controlled by a hydraulic system arranged outside the filter cylinder. The hydraulic system supplies the oil by the hydraulic pump (6). A tribit cross-joint hand operated direction valve (5) switches the oil feeding direction. A hydraulic lock (9) for controlling the pressure maintaining pressure and increasing the pressure maintaining time and an energy accumulator (10) are arranged in the hydraulic system. The hydraulic pressing device has features that: convenient adjustment of the pressing force of the container upper cover, reliable close and seal and reduced labor intensity of opening the cover and decontamination. The hydraulic pressing device is also used for connecting the flange end covers of similar other pressure containers.
Description
Technical field:
The utility model relates to a kind of open and close of pressurized container flange end cap.Adopt the small-sized hydraulic system of band accumulator, the control oil hydraulic cylinder is held the pressurized container end cap, makes it reliably airtight.The closing force of end cap can be regulated and by the accumulator pressurize.
Background technique:
Magnetic-grid-type high-viscosity oil filter is a kind of fluid filtration processing equipment, and its loam cake (1) needs the frequent cleaning pollutant of opening.Be full of fluid in the pressurized container main body filter cylinder (3), according to use condition, the oil liquid pressure difference, it is tight closed to require loam cake to be pressed on the filter cylinder.The original equipment loam cake by oil hydraulic cylinder jack-up with close, after loam cake resets, adopt known interconnection technique, by bolt loam cake is fastened on the filter cylinder, it is unadjustable, wayward to connect pressure, opening loam cake needs screw bolt by hand, wastes time and energy.
Summary of the invention:
Pressurized container, as magnetic-grid-type high-viscosity oil filter, as shown in Figure 1, its loam cake (1) must be pressed in filter cylinder (3) and go up tight closure, and the required impacting force of loam cake is relevant with fluid pressure in the cavity volume.Be the cleaning cavity volume, loam cake needs frequent the unlatching.Original equipment is fastened on loam cake on the filter cylinder (3) by bolt (2), operation inconvenience.The utility model adopts the control of small-sized hydraulic system, and that realizes loam cake opens and closes, compresses operation, has cancelled connecting bolt (2), easy to use and reliable.
As shown in Figure 2, the utility model is provided with oil hydraulic cylinder (4) at the center of filter cylinder (3), but jack-up with close loam cake (1).After loam cake resetted, the hydraulic cylinder piston rod chamber was a high-pressure and hydraulic oil, in order to the tension loam cake.High-voltage oil cavity is connected with hydraulic accumulator simultaneously, prolongs the dwell time, the control dwell pressure.
Hydraulic system as shown in Figure 3.The fuel feeding of control oil hydraulic pump (6) switches by 3-position 4-way hand-operated direction valve (5), and oil hydraulic cylinder fuel feeding that can be in filter cylinder opens or closes loam cake.After the loam cake closure, the control oil hydraulic pump continues to accumulator (10) fuel feeding, until reaching the required impacting force of loam cake, and keeps certain hour.Hydraulic lock (9) can increase the dwell time.Dwell pressure when pressure gauge (8) observable loam cake compresses, primer fluid press pump when pressure obviously descends is to the accumulator repairing.
Characteristics of the present utility model are to strain loam cake, pressurized container is closed sealing with oil hydraulic cylinder.Impacting force is easy to adjust, it is reliable to close sealing; Reduced the labor intensity of the scrubbing of uncapping.Make that the use of magnetic-grid-type fluid filter is convenient.

Embodiment:
The utility model can be exclusively used in magnetic-grid-type high-viscosity oil filter.Oil hydraulic cylinder (4) places filter cylinder (3) center jack-up, closes and compress loam cake (1).
Hydraulic system shown in Figure 3 places the filter cylinder outside, by the oil hydraulic cylinder fuel feeding of the control port among Fig. 2 in filter cylinder.Move 3-position 4-way hand-operated direction valve (5) to position, a left side, the fuel feeding of control oil hydraulic pump (6) enters the oil hydraulic cylinder rodless cavity, the jack-up loam cake; Move the 3-position 4-way hand-operated direction valve to right position, the fuel feeding of control oil hydraulic pump enters the oil hydraulic cylinder rod chamber and closes loam cake.After the loam cake closure, the control oil hydraulic pump continues to accumulator (10) fuel feeding, until reaching the required impacting force of loam cake, and keeps certain hour.Hydraulic lock (9) can increase the dwell time.Dwell pressure when pressure gauge (8) observable loam cake compresses, the loam cake impacting force can be controlled easily, regulate.
The utility model also can be used for similarly, and the flange end cap of other pressurized containers connects.
Claims (1)
1. the hydraulic compressing device of pressurized container flange end cap is characterized in that, by oil hydraulic cylinder (4) jack-up that places pressurized container main body filter cylinder (3) center, close and compress loam cake (1); Stretching of oil hydraulic cylinder by the HYDRAULIC CONTROL SYSTEM that places the filter cylinder outside; Hydraulic system is by oil hydraulic pump (6) fuel feeding, and 3-position 4-way hand-operated direction valve (5) switches the oil-feed direction, and hydraulic system is characterised in that the may command dwell pressure, increases hydraulic lock (9) and the accumulator (10) of dwell time.
