Description

ycTPCjCT o for cleanup

The proposal relates to cleaning equipment for the construction of devices for cleaning liquids using membrane technology.

A device for water purification is known - a household water purifier Cascade NLP Biotechprogress. Passport. The device comprises a membrane module, a water supply pipe to the module, connected to a shut-off valve, not a water pipe, a flush water drain pipe with an adjustable throttle and a purified water outlet pipe,

Membrane household appliances for producing drinking water Rucheyek - I and Rucheek - r Polymersynthesis JSC are also known. Passport having a similar design.

The disadvantage of such devices is the presence of two separate controls - a shutoff valve on the fluid supply line and an adjustable throttle on the drain line. To use the device, it is necessary to open the shut-off valve and supply liquid to the membrane module, then rinse the flow part of the device with a full stream of water with an open throttle, and then increase the pressure in the module by closing the throttle bore and select purified liquid. The device is turned off in the reverse order, i.e. the throttle opens, the device rinses, after which the shut-off valve closes.

The presence of two separate control flanges complicates the operation and causes difficulties for the user, which leads to the fact that the device does not rinse, dirt accumulates in the membrane module, which reduces the cleaning efficiency and reduces the service life of the device.

The proposed utility model is aimed at creating a device for cleaning liquids, in which the shut-off valve and adjustable throttle are kinematically connected and controlled by a single control element - a common handle.

This simplifies the operation, improves the cleaning efficiency E increases the service life of the device.

JTO is achieved by the fact that the proposed device contains a membrane module connected by pipelines with a shut-off valve and an adjustable throttle, which are located on the cavities of the entire body, separated by a seal, the valve and throttle currents are kinematically connected to each other, and the throttle rod is equipped with a control handle.

the kinematic connection of currents and the presence of an obtsev control handle provide the required technical result - flushing the device at each turn on and off E mandatory.

To gig. 1 shows the hydraulic circuit of the device, figure 2 shows a drawing of a shut-off valve and an adjustable throttle.

The proposed device for cleaning liquid contains a membrane module I, a pipe 2 for supplying liquid to the shutoff valve L, a drain pipe for flushing water 4 with an adjustable choke 5, a pipe for draining the purified liquid 6. The shutoff valve is installed in the cavity 7, and the adjustable choke is installed in the cavity 8 of the common 9. Housings are separated by 1C seal. the check valve contains a handle I, and a stem 12 with a threaded portion. The adjustable throttle contains a throttling element 1b and a rod 14 with a threaded end. partly, the current has a seal of 15. JIOKII of a shut-off to apai-vegulative growth of villages: .-: nematically connected between sooo ::. .the throttle current is equipped with: control coil 16., threaded tea link 1 .. the currents provide a time interval when the control handle is rotated from the moment at which the cross-section of the shut-off valve is fully open and the beginning of the overlap of the drain cross-section by the throttling element.

/ works as follows. I, when the handle is rotated 16 liters; the current 14 of the inductor 5 rotates and transmits the rotation to the stem 12 of the valve b. In this case, due to the threaded part of the stem L.C, the plate II rises to the liquid, begins to flow into the membrane module I, passes through its flow part: through the pipeline 4 B the cavity comes from the t- housing. ; this

I am interrogating w: element 1b does not overlap the discharge cross-section and the membrane module is flushed with a full fluid flow, and due to the length of the threaded parts of the rods, the plate II and the throttling element 13 are moved, at which there is a time interval for which the passage section of the shut-off element the valve is open, and the drain cross-section of the adjustable throttle is not yet blocked, a time interval of the order of 10 seconds is sufficient to flush the device.

With the further rotation of the handle 16 of the throttling element 1c, it begins to overlap the drain cross-section, in the flowing part of the membrane module I the liquid pressure increases, it is filtered through the membranes and the purified liquid flows through the pipe 6 to the consumer.

After selecting the required amount of purified liquid, the handle 16 rotates in the opposite direction. In this case, I throttle and the element 1b opens the drain cross-section, the membrane module is flushed, after which the U plate closes the cross-section of the shut-off valve and the flow of liquid into the device stops.

Thus, each time the device is turned on and off, it is rinsed without fail during one operation - rotation of the control handle.
