Description

The utility model relates to valve engineering, in particular, to high pressure hydraulic plates used in hydraulic systems for mounting controlled solenoid valves on them to open and close the fluid flow.

There are solutions for organizing the operation of the valve group by means of a set of passage channels from universal fittings and fittings. The first drawback of this solution is the large number of detachable connections, the second drawback is the large dimensions of the assembled typesetting unit, due to the impossibility of a set of fittings of the required size to bring the solenoid valves closer to minimum distances from each other, subject to the condition of maintaining maintainability and the ability to control all assembly elements , the third drawback of existing solutions is the high cost, since the assembly is carried out from several elements (fittings and fittings), and there is a need to use fixing and sealing compounds during assembly.

Closest to the claimed technical solution is a hydraulic mounting plate (patent RU 131527, publ.: 08.20.2013 Bull. No. 23), comprising a housing having holes for mounting the hydraulic apparatus and holes for draining and supplying fluid to the hydraulic apparatus, interconnected internal channels.

The task to which the claimed utility model is directed is the layout of the hydraulic plate, which allows minimizing the size of the occupied installation and provides the necessary operation scheme.

This problem is solved in that the hydraulic plate includes a housing having holes for mounting solenoid valves and holes for draining and supplying fluid to the solenoid valves, interconnected by internal channels, also contains a hole for the pressure sensor, and the number of holes for solenoid valves is four, located in this case in pairs on adjacent faces of the plate, the channels for the fluid flow are formed in such a way that the inlet channel is configured to receive fluid to the first pair of valves and the pressure sensor installed on one side, from where the channels have two outputs for connecting consumers, auxiliary outputs leading to the second pair of valves located on the other side of the plate, beyond which the fluid flow is combined into a single fluid drainage channel, exit the connection outputs from these channels.

The technical result provided by the given set of features is the solidity and compactness of the slab, expanding the arsenal of technical equipment for a similar purpose.

The layout and organization of the channels inside the developed hydraulic plate allows you to achieve the minimum overall dimensions of the occupied installation and to provide the necessary working scheme due to the maximum proximity of the electromagnetic coils to each other, as well as the diversity of their fastening along two adjacent walls of the plate.

The utility model is illustrated by drawings, which depict:

figure 1 is a view of a hydraulic plate in section along,

figure 2 is a cross-sectional view of a hydraulic plate,

figure 3 is a sectional view of a hydraulic plate,

figure 4 - schematic hydraulic diagram of the work,

where 1, 2, 3, 4 are the mounting points of the solenoid valves,

5 - place of installation of the pressure sensor,

6,7,8,9 - solenoid valves

10 - pressure sensor,

A, B, C, D - channels.

The inventive utility model is a monolithic one-piece hydraulic plate for placing on it 4 solenoid valves 6-9 located in pairs on adjacent faces of the plate. In the cavity of the plate there are channels A, B, C, D.

Schematic hydraulic diagram of the organization of the finished valve block is presented in figure 4. Valves 6, 7, 8, 9 (Fig. 1) controlled normally closed. The fluid through the channel A (Figure 1) enters the valves 6, 7 (Figure 1) and to the pressure sensor 10 (Figure 1). Then, through the valves 6, 7 (Fig. 1), the fluid enters the channels B and C (Fig. 1), respectively. Channels B and C have two outputs for connecting consumers. Auxiliary channels leading to valves 8, 9 (Figure 1), respectively, go to the connection outputs from lines (channels) B and C (Figure 1), respectively, behind valves 8, 9 (Figure 1), the fluid flow will be combined into line D ( Figure 1).

The advantages of the claimed device are:

monolithic structure due to its manufacture from a single bar of metal, satisfying the requirements for strength (not to be destroyed by constant working pressure), by machining, drilling and milling of working surfaces,

compactness due to the individuality of manufacturing a hydraulic plate for a specific model of solenoid valves, it is possible to achieve the maximum approximation of the valves to each other, and the placement of the valves in pairs on adjacent faces minimizes the size and the required amount of material of the original billet for the production of a hydraulic plate,

low manufacturing cost and low requirements for equipment used in manufacturing in comparison with the design of universal fittings, since the number of detachable joints is minimized and a standard section metal bar is used as the initial workpiece, the operations and time of machining (drilling, turning and milling) is performed in a smaller volume, due to this, the cost of production is reduced.
