The invention relates to regulating devices, namely, controllers, flow-pressure characteristics of the fluid, and can be used to regulate, for example, flow-pressure characteristics domeabra devices for sprinkling machines.

Known flow limiter, comprising a housing, a working chamber, the orifice, piston, spring, adjustable Windows, outlet fitting (Nikitin GA, Komarov A.A. Distribution and control device of hydraulic systems. - M.: mechanical engineering, 1965, PP 156).

The disadvantage of this flow limiter is the lack of accuracy and uniformity of regulation.

Also known pressure regulator, comprising a housing with a Central inner part, the input and output cavities, between which is a regulatory body made in the form of saddles and locking element associated rod with a spring-loaded sensing element that defines a cavity located therein by the spring of the sensing element and the control cavity (Flow pressure regulator //the Copyright certificate of the Russian Federation No. 2096819, CL G 05 D 16/06, F 16 K 17/04, 1994).

The disadvantages of this pressure regulator is the design complexity and increased hydraulic losses in regulation.

The purpose of this invention is to simplify the design and reduce their hydraulic losses in regulation.

This goal is achieved by the fact that in the known regulator comprising a housing with an inner part consisting of oral administration, coaxial input and output cavities, between which is a regulatory body made in the form of the locking element, rigidly connected with the rod, and the spring locking element, the control cavity is made in the form of two lateral cylindrical branches connecting the input and output cavity, and the locking element is made of cylindrical shape and is telescopically in the input Cup, rigidly connected with the side of the cylindrical branches, with the possibility of axial movement therein and partially overlap the side inlet cavity control, and the rod of the locking element is passed through the hole in the bottom input of the Cup and is rigidly connected with a coaxially positioned cylindrical shank having an exit through a hole in the bottom of the output glasses in the output cavity and mounted for axial movement and education side of the annular gap with the output Cup, whereby the output Cup is rigidly connected with the side of the cylindrical branches and has an output in the output cavity. The shank is provided with a limiting flange abutting against the outer side in the bottom of the output Cup, and a spring one end of which rests with the outside the second side in the bottom of the input Cup, the other end of which is restrictive in the flange.

The drawing shows a General view of the regulator flow-pressure characteristics.

Regulator flow-pressure characteristics includes a housing 1 with the inner part 2, consisting of cavity control 3, coaxial input 4 and output 5 cavities between which is the regulatory body 6 made in the form of locking element 7 is rigidly connected with the rod 8 and the spring 9 of the locking element 7. Cavity control 3 made in the form of two lateral cylindrical branches 10, connecting the input 4 and output 5 of the cavity. Moreover, the locking element 7 is made of cylindrical shape and is telescopically in the input glass 11, is rigidly connected with the side of the cylindrical branches 10, with the possibility of axial movement therein and partially overlap the side openings 12 of the control cavity 3. The stem 8 of the locking element is passed through the hole 13 in the bottom input of the Cup 11 and is rigidly connected with a coaxially positioned cylindrical shank 14 with the outlet through the opening 17 in the bottom of the output Cup 15 in the output cavity 5 and installed with the possibility of axial movement and education side of the annular gap 18 with the output Cup 15. When the output of the glass 15 is rigidly connected with the side of the cylindrical branches 10 and has an output in the output cavity 5. XB is stovik 14 provided with a limiting flange 16, abutting against the outer side in the bottom of the output Cup 15, and the spring 9, one end of which rests against the outer side in the bottom input of the Cup 11 and the other end into the restrictive flange 16.

Regulator flow-pressure characteristics is as follows.

Controller has two basic modes of operation: static and dynamic.

When the controller is in a static mode, i.e. with the increase of inlet pressure to the regulator up to the set pressure, the shut-off element 7 is stationary, the water pump is fed into the input cavity 4 of the housing 1, then through a cylindrical junction 10 of the cavity control 3 - in output cavity 5, and the output cavity 5 water delivered to consumers.

When the controller is in dynamic mode, i.e. when the pressure increases above configuration, the pressure increase in the input cavity 4 and the output cavity 5, the resulting water has a high pressure through a cylindrical shank 14 of the shut-off element 7. The locking element 7 is rigidly connected with a rod 8, overcoming the force of the spring 9, begins to move in the direction of the input cavity 4, overlapping the two lateral cylindrical holes 10 of the control cavity 3. Overlap lasts as long as the force acting on the cylindrical shank 14 and the associated closing element 7 by the spring 9, no urav beside force the current from the liquid.

The area of the outer end of the shank 14 must be larger than the area of the outer end of the locking element 7.

Setting the knob to the desired flow-pressure characteristics is made by selecting the appropriate stiffness of the spring 9 or prior to its compression.

The effectiveness of the invention is that the simplification of the structure of the regulator flow-pressure characteristics will reduce the consumption of materials, cost, increase service life and reduce the energy intensity of the regulatory process.
