Description

The invention relates to hydraulic construction and can be used as a water outlet for irrigation systems with automatic water regulation downstream.

The purpose of the invention is to increase the efficiency of the controller by reducing the control force.

The drawing shows the proposed bodovtusk about

The automatic tubular inlet includes a water outlet pipe 1, a shield valve 2 mounted on the axis of rotation 3, and a variable volume chamber 4 which is formed by a pressure shield 5, a base 6 and a flexible shell 7 fixed along the perimeter

At the moment of reaching the given level, the float 10 and the pressure shield 5

The base and the pressure shield 5, the pressure shield 5 is rigidly connected to one 20 occupy the upper extreme position, of the edges with the shield shutter 2. The variable volume chamber 4 has a variable volume 4 connected to the outlet pipe 1 by the outlet using a rod 9 to prevent clogging of the chamber 4 and a variable volume, the Panel shutter 2 is controlled by a float 10, which is connected by a rod 11 to a pressure shield 5, the latter is mounted on the axis of rotation 3.

the maximum volume, the shutter gate 2 is closed, the water supply to the lower pool is stopped. It also maintains the equality of moments from the pressure of water on the pressure shield 5 and the shield valve 2,

In the case of lowering the water level, the reverse occurs. Float

The principle of operation of the automatic tubular vodovkusk is based on the balancing of the moments relative to the axis of rotation from the water pressure on the Shield valve 2 and the pressure shield 5,

The control force is created by moving the float 10 up or down, which unbalances the equilibrium system. When it goes up (when the level rises), the shield gate 2 closes, and in the opposite case it opens. Therefore, in order to reduce the control force, the automatic tubular water flow should be calculated so that the moments from the water pressure on the shield valve 2 and the pressure shield 5 are equal to each other. This is achieved by selecting an effective pressure head area.

 10 moves downstream of the level, so the pressure shield 5 is lowered, the volume of the variable volume chamber 4 decreases, and the shield gate 2 begins to open. Water refills em

Invention Formula An automatic tubular water inlet, containing a shield valve, mounted on the flow hole of the water pipe and on the axis of rotation 45, float, distinguished by the fact that, in order to increase the efficiency of the regulator by reducing the control force, it contains a variable-volume chamber 5 and the size of the water outlet, formed by the pressure shield, 8, mounted on the axis of rotation, the base works by the following enclosure and flexible shell, fixed at times along the base perimeter and head Initial position: a float of a shield connected rigidly by one 10 and a pressure shield 5 occupy the bottom 55 of its edges, with the shield shutter and the extreme position, the chamber 4 is variable-connected with the float, than Ka dimensional volume has a minimum volume, a measure of variable volume connected to the shield gate 2 is fully open, hydraulically vodovtusknoy pipe. to 15 Water through the discharge pipe I from the upstream reaches the downstream. In this case, the magnitudes of the moments from the water pressure on the shield valve 2 and the pressure shield 5 are the same. Equality is preserved due to the fact that water acts not only on the shield valve 2, but also on the pressure shield 5. The opening force is created by the mass of the float10. As the lower pool is filled, the float 10 with the pressure shield 5 begins to move upwards, water through hole 8 enters the chamber 4 of variable volume. As a result, a closing force arises and the shield gate 2 begins to close, At the moment of reaching the given level, the float 10 and the pressure shield 5 20 occupy the upper extreme position, the variable volume chamber 4 has 0, the upper extreme position occupies, the variable volume chamber 4 has five the maximum volume, the shutter gate 2 is closed, the water supply to the lower pool is stopped. It also maintains the equality of moments from the pressure of water on the pressure shield 5 and the shield valve 2, In the case of lowering the water level, the reverse occurs. Float 10 moves downstream of the level, so the pressure shield 5 is lowered, the volume of the variable volume chamber 4 decreases, and the shield gate 2 begins to open. Water refills em 35 downstream to a predetermined level. In this case, the equality of the moments from the water pressure on the shield closure 2 and the pressure shield 5, 40 Invention Formula An automatic tubular water inlet, containing a shield valve, mounted on the flow hole of the water pipe and on the axis of rotation 45, float, distinguished by the fact that, in order to increase 1i10 It s 7 /// / eight / / 3 2 Editor A.
