(57) Abstract:The invention relates to hydraulic engineering and land reclamation, and is intended to stabilize the flow of water when the water supply from the water intakes of units, from shallow pools daily regulation of the major channels of the lowlands, etc. the Technical result - the reduction of metal constructions of the stabilizer. Flow sensor water contains mounted on the tubular outlet of a cylindrical box-shaped sectional shutter, the base of which is made in the form of a truncated cone attached to the horizontal base plate, made in the form of a plate, rod actuator and tube failure vacuum. This flow sensor is made in monoblock fixed on the racks still in foundations of structures above the culvert. Under the horizontal plate on rod drive is a disk valve with a diameter less than the diameter of the horizontal plate. In turn, the drive shaft is provided with an additional channel to disrupt the vacuum. The regulation is carried out by changing the coefficient of discharge as a function of changes of the head H, and also due to changes in the area of the expiry of W = f (N). 1 C.p. f-crystals, 2 Il. From the from the water intakes of units, from shallow pools daily regulation of the major channels of the lowlands, etc.Known stabilizer consumption of water containing the shutter with broken vertical flow cavity formed by the system of surfaces coaxially mounted cylinders of different height and diameter, the base cavity of the shutter is formed connected to the cylinders, truncated cones. The shutter is connected to the actuator and mounted on the bottom discharge .The disadvantages of this device is a high intensity due to device a cylindrical bolt with truncated at the base of the cone on the whole height of the building, the introduction of advanced coaxially arranged cylinders of different heights connected with a truncated cone, and the increase in the parameters of the structure by increasing the size of the stabilizer.Closest to the proposed stabilizer is a water flow containing installed on the outlet and coupled with the drive of a cylindrical shutter made graded and divided into the flow cavity vertically in diameter spaced plates, the base of which is made in the form of a truncated cone, and the base of the vertical plates keeping the diameter of the conical base of the cylindrical shutter .The disadvantages of this device is a high intensity due to device a cylindrical shutter with vertical plates flow cavities, truncated cone and the horizontal plate at the base of the vertical plates of metal, devices, heavy lift and gravity forces rise, and consequently, the complexity of the operation to control the flow sensor.The objective of the invention is the reduction of metal stabilizer water flow.The technical result is achieved by the fact that the stabilizer of the water flow is made in monoblock (concrete, reinforced concrete or other replacement metal) of the cylindrical box-shaped sectional block formed by vertical walls, the base of which is made in the form of a truncated cone attached to the end of the horizontal plate, made in the form of a plate and provided with a tube vacuum breakdown, mounted on stands motionless in the foundations of buildings above the outlet, and is provided under the plate on the rod of the actuator disk valve, and the stem has a longitudinal channel for disrupting the vacuum under it.Flow sensor water are presented in Fig.1, 2 in section, and contains corobo the ru vertically spaced plates 2, at the base of which is secured a horizontal plate 4. The plate is made in the form of a plate and provided with a tube vacuum breakdown 5 diameter smaller than the diameter of the truncated conical base 3, is rigidly fixed to the uprights 6 still in the foundations of buildings at a height above the outlet 7. Under the horizontal stabilizer plate 4, made in the form of a plate, set the disk valve 8 on the rod of the actuator 9, and the rod has a longitudinal channel 10 for disrupting the vacuum. The longitudinal channel running or flowing within or flowing from the side. The diameter of the disk valve is made not less than the inlet diameter of the outlet 12, the actuator 9 is provided with a frame 13 mounted on the service bridge 14.The stabilizer is fixed on stands motionless in the foundations of buildings at a height above the outlet. Value and is based on the passage of the maximum flow rate of Qmax. This disk valve 8 is in its upper position.The stabilizer of the water flow works as follows. When the level of the upstream to HcalcHmin(equal to the elevation of the edge of the lower stage cylinder monoblock 1) after going under the conical base 3 of the cylinder 1. This coeffi error 5%). Indeed, if we'll get:
where Wy=AB is the area of the annular gap, a constant value, sincea - constant due to the harsh provisions of the monoblock;
b - the circumference of the outer cone on the edge of the expiration from under him, also the value of the constant, is a constant value.As growth pressure upstream of the N consumption ratio begins to deviate from the value (increases), but upon reaching the head H Hracesstarts overflow inside the cylinder (the first lower stage) and the water cavity to the inside of the cylinder 1 formed by the separating plates 2, starts flowing towards the main stream, providing additional hydraulic throttling and as a consequence the reduction of the coefficient of discharge, restoring with acceptable accuracy. The further growth of the head work will increase, and you reach a stage cylinder 1 reaches the maximum allowable deviation, but upon further excess N starts overflow inside the cylinder through the next step, and again the process is restored, restoring the law changes with acceptable accuracy. But upon further excess N starts overflow through the following STI accuracy until Hmax. The number of stages is determined by the required accuracy of stabilization. With respect to reclamation facilities enough to have 3-4 steps to ensure the stabilization of the flow rate with an accuracy of 5%. It is permissible level fluctuations, and hence, Nmaxthe more Hmin.Changing the setpoint of the flow of water in the proposed stabilizer is carried out by changing the position of the disk valve (below). The flow of exhaust in the exhaust, will depend on the size of the opening of the disk valve. We denote this discovery is the distance from the disk valve to mark the entrance to the bend and we denote it as' (in the drawing shown by the dotted line opening). We denote the length of the diameter of the disk valve b'. Then the area of the opening is equal to W =a b' and the flow rate of exhaust flow in the exhaust will be:
< / BR>where is the coefficient of discharge discharge from under the disk valve has a magnitude depending on the and'. Qmaxis the flow coming from under a truncated conical base 3, as its position is always in effect a rigid monoblock, i.e., Qmax=const, then , a', b' standing for this and that', and hence Q'=const.The application of the proposed device will allow you to get a significant economicial.Sources of information
