Description

(54) DISTRIBUTIVE DEVICE

I

The invention relates to pipe fittings, in particular to devices, for the distribution of streams of highly viscous and chemically aggressive liquids in hydraulic devices used in the chemical and petroleum industries, as well as in the production of building materials.

A multi-port crane is known, comprising a housing with nozzles, a locking mechanism consisting of an obtuse elastic cuff of a fixed sleeve, in the side walls of which pushers are installed, and control plugs flj.

The disadvantage of this device is the rapid wear of the elastic cuff due to: pressing the pusher against the body and producing the sleeve in the place - location of the pushers. In addition, the device does not allow the flow in several directions.

The closest in technical essence is the distributor. -

NO device for LIQUID flow:

containing body with T-shaped pro-. passage channels and two kirschs, volatile bodies in the form of two elastic membranes located between the covers and the SOUTH housing surfaces and the pneumatic drive of the G2D membranes.

The disadvantages of the E1 "device-gaa is oo medium complexity of structures and the impossibility of using it

10 for distributing two parallel liquid streams.

The purpose of the invention is to expand the functional capabilities of the device with minimal dimensions.

Claims (1)

The goal is achieved by the fact that there are oval grooves on the face surfaces of the casing, and in the curvature of the hooks there are reciprocal grooves connecting the casing through channels in pairs, which is 70 than the opposite grooves; The 1X sides of the case and the covers are arranged in mutually perpendicular directions. 3 In FIG. 1 shows a distribution device, a section in FIG. 2 is a section A-A in FIG. 1. Switchgear contains body 1, in which four T-shaped bypass channels 2-5 with flanges 6 are made, two oval grooves 7.8 each on the ends of the body, connecting in pairs T-shaped flow channels, clamps 9.10 in which there are oval nozzles 11,12, counter slots 7,8, inlet and outlet nozzles 13-16, nozzles for supplying compressed air 17,1 8 and channels 19 al compressed air, drive control diaphragms 2O, between the caps and the ends of the body surfaces are 2 elastic membranes 21 and 22. Oval grooves vopolozhnyh krpiek sides of the housing and arranged in one-perpendicular directions. The device works as follows. Compressed air through the actuator 20 from the network with a pressure exceeding the pressure of the working fluid enters in one direction, the device between the cap 9 and the membrane 22, while the membrane presses to the shoulders 6, T-shaped transfer channels and overlaps the openings of these channels with one parties. In this case, the working fluid, which is under pressure, comes in two streams: into the inlet connection. ., 14, from any liquid source and into the inlet 13 from any liquid source and into the inlet 13 from the metering device (for example, from a chamber dispenser), enters the T-shaped channels 2 and 3, presses on the membrane 22, clamping it to the wall 9 and flows through the oval grooves to two other T-shaped channels 4 and 5 in which the holes adjacent to the membrane are blocked and the others are connected to the nozzles and exits from the outlet nozzles; from one to the receiving tank, and: from the other to the metering device 54. Further, by switching the compressed air to the other side of the device, the membrane 21 is pressed against the holes T-h) of the bores in order to intersect them, and the membrane 22 releases the holes of the T-shaped channels and the working fluid enters the dosing device through two distributors from two sources of liquid. , and from the dosing device to the receiving tank. When the compressed air is supplied to both sides of the device, all the openings of the T-channels are blocked. The use of a distribution device in installations, for example, to obtain a foam, can increase productivity and increase the reliability of the device. Claims of the invention: Distribution device for fluids in liquids, comprising a housing with T-shaped passage channels and two lids, shut-off members in the form of two elastic membranes located between the clamps and end surfaces of the housing, and the drive for controlling the membranes are different. The fact that, with a chain of expanding the functionality of the device with minimal dimensions, there are oval grooves on the end surfaces of the body, and in the claws there are weighted grooves connecting the housing two pairs of channels, and the grooves on opposite sides of the body and lips are located in mutually perpendicular directions x Sources of information format (taken into account during the examination 1.
