Controlled discrete throttle consists of through case, of nut, of valve in form of hollow cylinder along generatrix of which there is made a row of through radial orifices at a specified interval and of specified diametre. The valve is connected to a setting shaft ejected outside through the nut and is contracted with a seat made as a bushing with a packing ring. The throttle also consists of a bushing with a scale whereon there are marked values of corresponding diameters of through orifices of the valve and an indicator. The valve rotates and conjugates its through orifices with the orifice of the seat. The valve is contracted with the seat installed into a boring of the case with the packing ring without an additional fastener. An oval slot is made at input of working medium into the case of the throttle. This slot is set off relative to lengthwise axis of the case downward. Also, width of the slot exceeds external diametre of the seat, while centre of upper radius of the slot is located on lengthwise axis of the case; the valve is contracted with the seat by means of force of the packing ring. Further, instead of the seat in the throttle case there can be made orifices internal diametre of which is equal to diametre of the orifice in the seat.

FIELD: construction. SUBSTANCE: water flow rate stabiliser includes water outlet tube 1 of a rectangular cross-section with seat 2 having shaped cut-out 3 that is used as a control element. Inside water outlet tube 1 an arrangement is made for a shutoff element made in the form of flexible belt 4 fixed with one of its ends to an upper wall of water outlet tube 1, and with the other one to the bottom of seat 2. Flexible belt 4 forms control cavity 5 with drain channel 6 together with the housing of the water outlet tube. The control also includes membrane housing 7, the cavity of which is connected via a pipeline to an upstream wall. Membrane 9 of membrane housing 7 is connected to valve 13 by means of stock 10 with adjustment screw 11 and spring 12. EFFECT: improving flow rate stabilisation accuracy. 2 dwg
The invention relates to hydraulic engineering and can be used to stabilize water flow in the tubular diaphragm and the floodgates. Known stabilizer of water consumption (see A.S. No. 1198465, MCL - G05D 7/00, 1985), containing a box-shaped shield, bottom gate, made in the form communicated with the upper and lower pools capacitance formed by the pressure shield, mounted on a horizontal axis of rotation and connected with a flexible sheath, enshrined in the foundations of buildings, and the valve is made in the form prescribed at discharge hole of the shield with visor connected through the rod from the arm, the shoulder of which is connected by means of an adjusting screw with a bottom gate. However, the known flow sensor has a low reliability in operation and does not provide stabilization of the water with a wide range of changes in water level upstream. Closest to the invention is the flow regulator (see A.S. No. 1275383, MCL G05D 7/01, 1984)containing the water outlet pipe of rectangular cross-section with a saddle covered by a locking member made in the form of a flexible tape, forming with the housing water outlet pipe control cavity communicated with the upper tail and have a drain channel that has a control element made in the form of a sleeve with a profiled cut valve, the mouth is fixed on the membrane, the second membrane housing, the cavity which is communicated with the control cavity, and connected by a rod with a membrane to the first membrane housing, a cavity which is communicated with the upper tail. The second membrane housing in a known regulator of water leads to the complication of its structure and, consequently, reduces its reliability, since the probability of failure due to possible driving his deposits and small fin. The technical result is the creation of a stabilizer water consumption of simplified construction and improved reliability while retaining the ability to provide increased accuracy of stabilization of the flow. The technical result is achieved that the flow sensor water containing the water outlet pipe of rectangular cross-section with a saddle covered by a locking member made in the form of a flexible tape, forming with the housing water outlet pipe control cavity communicated with the upper tail and have a drain channel on which you installed the valve is connected by a rod with a membrane of the membrane housing, the cavity which is communicated with the upper tail, the control with shaped cutouts, according to the invention as a control element used saddle into the water pipe. The novelty of the claimed technical solution is that in the stabilization of the ora of water flow as the control element used saddle into the water pipe and it allows for increased precision stabilization of consumption. The invention is illustrated by drawings, where figure 1 shows a General view of the flow regulator; figure 2 - a section a-a figure 1. Flow sensor water contains water outlet pipe 1 of rectangular cross-section with the seat 2, having a shaped neckline 3. Inside the water outlet pipe 1 is placed a stop valve, made in the form of a flexible tape 4 attached at one end to the top wall of the water outlet pipe 1, and the other to the base seat 2. Flexible strip 4 forms with the housing water outlet pipe control cavity 5 with the drain channel 6. The stabilizer also includes a diaphragm housing 7, the cavity of which is connected by a pipe 8 with the upper tail. Membrane membrane 9 of the housing 7 by a rod 10 with a screw setpoint 11 and a spring 12 is connected to the valve 13. The stabilizer of the water flow works as follows. When the water level in the upstream due to the presence of the pipeline 8, the pressure in the diaphragm casing 7 increases, the membrane 9 is bending, compressing the spring 12 and moving the rod 10, and with it the valve 13. This decreases the degree of opening of the discharge channel 6 and, consequently, to reduction of the flow of water discharged from the control cavity 5. The pressure in the latter will begin to increase equality between the flow rate of water flowing into the control cavity 5 through the clearances between the casing modulebus the first pipe 1 and the loose edges of the flexible tape 4, and discharged flow will be disturbed, flexible tape 4 will come into motion and begin to overlap shaped cutout 3 of the seat 2. Upon completion of the transition process equality between incoming and discharged expenses will be restored and the flexible tape 4 will occupy a new position. In this case, due to the presence of a shaped cutout 3 of the seat 2, used as a control, the new position of the flexible tape 4 will correspond to the degree of opening of the recess 3 of the seat 2, to compensate for the increased flow rate when the water level upstream. During the lowering of the water level upstream of the cycle of operation is repeated in reverse order. The adjustment of the stabilizer of water consumption for different modes is carried out by the screw setpoint 11. In this flow sensor water availability profiled cutout 3 of the seat 2, used as control, allows to obtain high accuracy of stabilization of the flow. The stabilizer consumption of water containing the water outlet pipe of rectangular cross-section with a saddle covered by a locking member made in the form of a flexible tape, forming with the housing water outlet pipe control cavity communicated with the upper tail and have a drain channel on which you installed the valve is connected by a rod with a membrane of the membrane housing, the cavity to the who communicated with the upper tail, control with shaped cutouts, characterized in that the control element used saddle into the water pipe.
