Description

one

This invention relates to the field of pipe fittings.

A regulating device for hydraulic systems transporting products with solid separators is known, which contains a pressure regulator with a bypass for passing the separators, which is blocked by a hydraulic locking device controlled by a distributor having an elastically movable rod.

The proposed regulating device differs from the known one in that a pusher interacting with them is inserted between the distributor shaft and the solid dividers.

This allows automatic control of the locking drive.

Figure 1 shows schematically an adjustable device.

The regulating device consists of a housing 1 with an inlet 2 and an outlet 3 with nozzles connected by openings 4 and 5 through a pressure regulator that has a seat 6 and a regulating member 7 connected to the membrane 8. The cavity A under the membrane 8 communicates with the opening 5 and through it - with the nozzle 3. The diaphragm 8 is acted upon by a regulating spring 9. In the case / having a sealing surface 10, there is a damper //, connected by a brush 12 with a piston 13.

Spring M is located in the cavity of the cylinder 15, which communicates with the atmosphere. The working cavity B of the cylinder is communicated by tube 16 to the inlet nozzle 2 through a spool valve, including a body / 7 with channels 18-20, preassigned for the passage of the medium with the actuator actuator, and a drip 21 intended for unloading the stem 22 from pressure. Rod 22 and pusher

23 are loaded 24. At the same time, through the brush 22, the channels S and / 9 and the tube 25 of the inlet pipe are in communication with the tube 16, and the pusher is extended into the flow area of the pipe.

When pressure is applied, it through the tube 16 acts on the slit 13, moving the flap //. The medium flows from nozzle 2 to nozzle 3 through openings 4 and 5. When the pressure after the regulator increases, the membrane 8, compressing the spring 9, moves the regulator 7 to the saddle 6, reducing the flow cross section and reducing the pressure after the regulator to a predetermined value. When the pressure decreases behind the regulator, the reverse occurs. When the separator enters the inlet 2, it turns the pusher 23, which moves the rod 22 to a position in which the channel 19 connects to the channel 20. The cavity connects to the atmosphere, and under the action of the spring 14, the valve 11 opens the passage to the separator, which under the action

the pressure medium moves through the valve 11 and further into the pipeline. After passing through the separator, the pusher 23 is released, the rod 22 by the spring 24 is moved to a position in which the cavity B is connected to the tube 25, and, under the pressure of the medium, closes the valve 11.

Subject invention

Control device for hydraulic products transporting systems, with

solid separators containing a pressure regulator with a bypass for passing the dividers, which is blocked by a hydraulic locking device controlled by a distributor having an elastically movable brush, characterized in that, in order to provide automatic control of the actuator of the locking device, between the brush the distributor and solid dividers introduced a pusher interacting with them.
