The invention relates to hydraulic engineering and can be used to pump water from a closed Prov./P> A device for regulating the water level in hydraulic structures containing located between the upper and lower pools the water outlet pipe, the outlet port to which the camera is installed, separated by a membrane on communicated between podobrannyy camera and namebrand camera, have a drain channel closed with float valves, and the upper part of the camera is plugged and installed below the level of the upstream and above the downstream water, and the membrane is installed with the possibility of overlapping the outlet of the water outlet pipe (A. C. USSR N 1087967 A, CL G 05 D 9/02, 1984).The disadvantages of this design are the possibility of silting namebrands camera, abrasion of the membrane sediment, in facing the flow of water, and the impossibility of clearing the excess pressure of the water supplied to the lower reach.Closest to the claimed invention is a regulator of the water level, consisting of a body with the power tube covers with drain holes, with valve stem and float attached by a lever to the rod (Merkuryev B. C. automation of water supply for pasture water // Hydraulic engineering and land reclamation. M. 1975, N 2. C. 90-95).The problem to which the invention is directed, is to improve operational reliability regulator water level.The technical result from the use of the invention is expressed in the exclusion of the possibility of water hammer, the increase in the time during which the controller operates fully open the water outlet hole, protecting the membrane from abrasion by sediment, which is in facing the flow of water, and protection podobrannoj camera from silting.The technical result is achieved that the control water level in hydraulic structures, comprising a housing with a power tube, closed at the top and bottom covers with drain holes, through which the piston rod is fixed in the lower part of the valve above the top cover, made in the form of a truncated inverted cone with a calibrated hole in the center, an additional camera, equipped with an outlet tube connected to the valve level sensor, closed over the economic structures.Control water level in hydraulic structures includes a housing 1 with a power pipe 2 and the outlet 3, the bottom cover 4 with the drain holes 5 and the top cover 6 made in the form of a truncated inverted cone with a cone angle of not less than the angle of repose of the sediment coming in podobrannyy chamber 7 through a calibrated orifice 8, the purpose of Nazarene podobrannoj chamber and the outlet tube 9. From the top to the top cover 6 metal ring 10 is attached elastic membrane 11, which are attached to the rod 12 with the exhaust valve 13, passing through a calibrated orifice 8. To control the operation of the controller is equipped with a breather pipe 9 connected by means of flexible hose 14 with a level sensor, consisting of a valve 15 with the float 16 and unit 17.The controller operates as follows.If the water level in the irrigation canal below the setpoint, the float 16 is in the lower position and the valve 15 opens the outlet of the outlet tube 9. The outflow of water through it leads to a decrease in pressure in podobrannoj chamber 7 and the displacement of the membrane 11 with the rod 12 and the exhaust valve 13 down to the opening of the outlet 3 of regulation 16 rises, the valve 15 closes the outlet of the outlet tube 9. Water from the penstock through a calibrated orifice 8 in the top cover 6 comes in podobrannyy chamber 7, where the pressure in podobrannoj chamber 7 is aligned with the pressure in the delivery pipe. Due to the fact that the surface of the diaphragm 11 is larger than the area of the outlet valve 13, the difference of the pressure on them leads to the displacement of the membrane 11 with the rod 12 and the exhaust valve 13 up to the ceiling outlet 3 outlet valve 13 and the supply of water in the irrigation canal.The proposed control level of water in the waterworks has a simple structure, is easy to manufacture and has a higher reliability compared to the prototype. 1.
