Description

2. The device according to claim 1, that is, in order to improve the sensitivity, it is equipped with an intermediate tank with an outlet located above the float chamber and a float with

The invention relates to hydraulic engineering and can be used to automate the washing of sediment water intakes.

The purpose of the invention is to ensure reliability as well as the sensitivities of the device.

Figure 1 shows the structure, general view; figure 2 is a sensor with a settling chamber, the section.

The device consists of installed in the upper and lower II sections of the settling chamber 1 sediment sensors, each of which consists of a float chamber 2, communicated with the sediment accumulation zone by pipeline 3. Intermediate tank 4 is connected by pipeline 5 to a water source, the level of which is higher than any tank Bbmie located maximum level in the settling chamber 1. At the outlet 6 of the intermediate tank 4 there is a float valve 7. The float actuators 8 and the float sensor 9 of the water level are connected to the pneumatic distributor ate 10-12 times. The pneumatic valve 12 is connected with a retainer made in the form of a float chamber 1 which is filled from above through the tube 14 of the intermediate tank 4, an outlet 15, on which a diaphragm valve 16 connected to the pneumatic valve 11 is mounted. The valve 12 is connected to the valve 17 .

The float actuator 8 of the 1st section is set above the level of the household depth at the maximum flow rate in the settling chamber.

The device operates as follows.

In the initial position from the water source, the level in which is higher than the level of any filled tank located above the maximum level in

valve installed in the float chamber, and the valve is installed in the outlet of the intermediate tank, and the water supply pipe is connected to it.

The settling chamber, through pipeline 5, receives water into the floating chamber 2 of the sensor and the anosone located in the station, then enters the container 4 and through the opening 6 into the float chamber 2 of the sensor located in the U container. The float drive 8 of the valve 1, afterwards, on the lever of the manifold 11, opens its lower valve and is connected to a membrane with a compressed air source; | valve 16, which closes the outlet outlet diaphragm 15. Since there is no sediment, as well as the level, the level of the panos sensor in the float chamber 2 is at the same level with the level of the spherical chamber 1, therefore the float valve 7 does not close the outlet 6 and water not through the pipe 14 D float chamber 13 of the locking device. The float drive 8, with its weight, opens the upper valve of the pneumatic distributor 12, through which communication with the gate of the water level sensor 9 takes place through the pneumatic distributor 10,

At the fence; water into the system to the sediment deposition monitoring engine located in || -batch of the settling chamber 1, the shutter maintains the set water level (I) with the help (with the float sensor 9, the distributor 10 connected with the source of compressed air through the upper valve of the distributor 12. And there can be three positions in the pneumatic distributor ten:

at a constant water level in the settling chamber, the position of the lever of the pneumatic distributor 10 is neutral, the upper and lower valves are closed, so the shutter is in a certain position; .

when the water level in the chamber is 1, the level 9 float sensor, acting through the pneumatic distributor lever 10, opens its bottom valve and connects the lower gate capacitance 17 to the compressed air source, part of the load is pushed out through the pipeline to the upper tank, as a result, the closing moment decreases and the shutter opens slightly and the water level drops to the set point;

at umeishen1P1 water level float sensor 9, the impact of their weight through the lever to the upper valve ppevmoraspredelitel 10 connects the lower gate capacitance 17 through the upper valve pnepmoraspredelitel 12 with the atmosphere and szhatp air leaves, and water is ca otekom LZ Bepxiieii container enters the lower part, the closure the moment is increased and the shutter 17 is covered, and the water level in the upstream is increased. In this mode, the shutter works to the Zaili1P1 sensor of sediment of the alignment M in the settling chamber.

In the mode of flushing sediment device operates as follows.

As soon as stnor II starts to fill up, the water level in the float chamber 2 of the sediment sensor rises so that the float valve 7 closes the outlet 6 of the tank A, as a result of which water enters the retainer float chamber 13 and fills it. The float drive 8 through the pneumatic distributor lever 12 closes the upper valve and opens the lower valve, squeezes the air from the compressed air source into the lower capacity of the valve 17, displaces water into the upper container and opens the valve, thus creating an odorless mode in the settling chamber. First, the sediment is washed away in the N section and the water from

the pop-up chamber 2 exits, the float valve 7 opens the opening 6 and the water stops flowing into the (Float-lock chamber. As soon as the sediment in the I section of the settling chamber is removed and the water level in the float chamber of the sediment sensor decreases to the household depth of maximum flow rate () the float drive 8 located slightly above the level, with its weight, acts on the lever of the pneumatic distributor 11, opens its upper valve. At the same time, the internal cavity of the diaphragm valve is connected to the atmosphere and opens into Outlet 15. Water from the float chamber comes out, and the float actuator 8, with its weight, acts on the lever, closes the lower valve, stopping the supply of compressed air to the shutter 17, and opens the upper valve of the pneumatic distributor 12. As the water level in the settling chamber at the sediment flush is much lower than the target, then the upper valve of the pneumatic distributor 10 is opened by the float sensor 9. Therefore, compressed air from the lower tank of the valve 17 through the upper valves of the valves 12 and 10 is released to the atmosphere, and water from the upper tank to the lower goes by gravity, so that the shutter 17 is closed20

given. At the same time, the float actuator 8, acting on the lever of the pneumatic {distributor 11, opens its lower valve and diaphragm valve 16 connected to a source of compressed air, closes the outlet I 15 of the retainer. The process is then repeated in the above sequence.

Thus, the invention will improve the reliability and sensitivity of the device.
