The importance of electric over hydraulic valve block
An electric over hydraulic valve block is a square that controls the workings of the hydraulic fluid, that is, a small device, usually made of metal, that is installed in a hydraulic system.
In hydraulic systems, we currently use more integrated configurations for hydraulic components. Among these, the integrated block type configuration features an electric-over-hydraulic valve block with mounted plate hydraulic valves. This design offers a compact structure and easy maintenance.
Electric over hydraulic valve block processing is a common method of connecting the hydraulic system without pipe (also known as cartridge valve), it not only simplifies the design and installation of the hydraulic system, but also facilitates the realization of the integration and standardisation of the hydraulic system, can simplify the installation of the hydraulic system, overhaul, replacement, as well as the maintenance of the late maintenance, is conducive to reducing manufacturing costs, improve precision and reliability. Surface mounted plate hydraulic valve, with a compact structure, easy maintenance.
Hydraulic valve block oil circuit block processing is a common method of connecting the hydraulic system tubeless (also known as cartridge valve), it not only simplifies the design and installation of hydraulic systems, and facilitate the realization of the integration and standardisation of the hydraulic system, can simplify the installation of the hydraulic system, overhaul, replacement, and maintenance of the late maintenance, is conducive to reducing manufacturing costs, improve precision and reliability.
Principle performance of electric over hydraulic valve block
This is related to the system pressure and hydraulic valve block processing diameter, hydraulic valve block processing on the general pressure oil port, working oil port, return port. Assuming we place the valve block on the plane, the internal forces on the horizontal direction orifice of the electric-over-hydraulic valve block are balanced. However, the force on its vertical orifice cannot balance itself, so we transfer this force to the base to balance it with its reaction force. The size of this force is equal to the working pressure × force area (the basic principle of hydraulics) i.e.: F=P1*pi*D^2/4+P2*Pi*D^2/4+……….. Where P is the pressure in different orifices and D is the through diameter of the valve block.
Therefore, in daily life, we observe that valve blocks with small working pressures and small diameters have thin fixed bolts. Conversely, valve blocks with high working pressures and larger diameters have thicker fixed bolts. Hydraulic valve block oil way block processing is a common method of hydraulic system tubeless connection, also known as cartridge valve. The importance of hydraulic valve block oil circuit block processing in the hydraulic system has been increasingly recognised, and its application range is becoming more and more extensive.
Conventional design process for electric over hydraulic valve block
Electric over hydraulic valve block has a less convenient place, that is, for each hydraulic system needs to be in accordance with the hydraulic schematic design of the oil block individually. As the complexity of the hydraulic system increases, the difficulty of designing the electric-over-hydraulic valve block also rises. If we do not carefully plan the design, we will face a complex manufacturing process, higher processing costs, raw material waste, and cumbersome maintenance.
Conventional design steps for electric over hydraulic valve block
1. Confirmation of schematic diagram and components
First of all, you need to divide the connections of valves and oil circuits according to the schematic diagram, and confirm the list of components, divide and organise the list of required components.
2. Establishment of database
It is necessary to find each standard part from the standard database, and also need to design and save some non-standard parts used.
3. Drawing the electric over hydraulic valve block three-dimensional drawing
When drawing the three-dimensional drawing of the electric over hydraulic valve block, it is necessary to determine the position of each valve mounting plate.
A. Create the shape of the block first.
B. Tentatively set the size of the oil circuit block shape.
C. Immediately after that, place the components. This involves identifying the mounting surface and hole models for the required components, and using command language to rotate and move the mounting surface to the appropriate position.
4. Oil hole connection
This process is needed to connect the holes to be connected together.When it is not necessary to calculate the depth and coordinates of the holes for connecting the oil lines, the designer can create a design using a two-dimensional expansion drawing. Additionally, a three-dimensional perspective drawing allows for a clear view of the oil line connections and facilitates modifications.
For each hydraulic system it is necessary to design the oil circuit block separately according to the hydraulic schematic diagram. The advantage is that it simplifies the installation, overhaul, replacement and maintenance of the hydraulic system. The disadvantage is that the design and processing requirements are high, the cost of a single piece is high, and it is not suitable for single-piece small batch production.
