Principle analysis: before manufacturing large-scale integrated valve block, it is necessary to use 3D drawing software to analyze the inner channel structure of the valve block, check and analyze the correctness and rationality of the channel combined with the schematic diagram, and analyze the sequence of channel processing.

The material processed by valve block shall be kept dense in structure, and there shall be no defects such as interlayer and sand hole. The blank shall be inspected before processing. Cast iron blocks and larger steel blocks should be aged and pretreated before processing.

Hydraulic valve block (referred to as hydraulic valve) is the control element in the hydraulic system, which is used to control the pressure, flow and flow direction of the fluid in the hydraulic system, so as to meet the requirements of different actions of the executive elements. Because of its compact structure, good sealing performance, convenient maintenance and confidentiality, it is used in hydraulic transmission system.

In order to achieve a certain control function on the valve block, it is often necessary to open many holes in the valve block. Some of the holes are used to facilitate the processing of other holes, which are often called process holes. In addition to the process holes, other internal oil passage ports also need to be plugged.

The steel ball is extruded into the sleeve longitudinally to make the sleeve expand radially. The sharp teeth of the annular groove around the sleeve are pressed into the material of the relatively low hardness process hole, or the sleeve itself is squeezed into the gap of the rough surface of the relatively high hardness process hole, so as to achieve the occlusal seal with the workpiece.

The oil hole in the oil circuit block should be in the whole range of working temperature and flow capacity of the system, so that the pressure drop caused by the fluid flowing through the channel will not adversely affect the efficiency and response of the system.

The system consists of hydraulic control unit, servo cylinder and power oil station. The hydraulic control unit consists of speed control valve control unit and turbine stator blade control unit. Each unit is composed of electro-hydraulic servo valve, electric solenoid valve, quick closing solenoid valve, oil circuit block and base.

The basic structure of Wuxi hydraulic valve block mainly includes valve core, valve body and control device which drives the valve core to move relatively in the valve body.

The hydraulic valve block can not only simplify the design and installation of the hydraulic system, but also facilitate the integration and standardization of the hydraulic system, reduce the manufacturing cost and improve the reliability.

The valve block is composed of various hydraulic valves connected with each other. A variety of complex control behaviors can be realized by the combination of different states of various valves connected to the valve block.

The hydraulic valve block processing system consists of hydraulic control unit, servo cylinder and power oil station. Now hydraulic valve block processing manufacturers - give you a brief introduction to the valve block composition.

The valve block is the key part of the integrated hydraulic system. It is not only the carrier of other hydraulic components, but also the channel body of their oil circuit. The valve block is generally rectangular in shape and made of aluminum or malleable cast iron.

For the hydraulic valve block, although most of its parts are connected by bolts, the hydraulic valve block is not disassembled when it is designed. If it is forcibly disassembled due to lack of equipment or technology, the result may be damage to the hydraulic valve.

Hydraulic valve Manifold valve mainly includes two-way Manifold valve, three-way Manifold valve and threaded Manifold valve. The two-way Manifold valve of valve block manufacturer is a kind of multi-functional composite valve which is composed of cover plate and pilot valve by inserting its basic components into the valve body of specific design and processing. Because Manifold valve has only two oil ports, it is called two-way Manifold valve.

Hydraulic system manifold block, also known as oil circuit block, valve block and valve island, mainly plays the role of adaptation, transition, conversion, expansion, expansion of hydraulic oil circuit block manufacturer interface and simplification of pipeline.

The raw materials (ductile iron, forging, steel bar, etc.) of oil way valve block shall be purchased in strict accordance with the drawing requirements. The raw materials purchased should meet the technical requirements.

The processing of hydraulic valve block, many people may only focus on technical issues, will ignore some auxiliary processing of hydraulic valve block, in fact, in the whole process of hydraulic valve block processing, auxiliary processing plays a very important part. Auxiliary processing includes valve body cleaning, parts deburring, heat treatment residue removal and cleaning.

The surface roughness of the valve and flange installed on the hydraulic valve block shall reach Ra0.4, and the surface roughness of the sealing surface of the end pipe joint shall reach ra3.2. In addition, the tolerance of perpendicularity between the screw hole of pipe joint and its outer joint surface shall be at least Grade 8.

The processing of hydraulic valve block, many people may only focus on technical issues, will ignore some auxiliary processing of hydraulic valve block, in fact, in the whole process of hydraulic valve block processing, auxiliary processing plays a very important part. Auxiliary processing includes valve body cleaning, parts deburring, heat treatment residue removal and cleaning.

Blackening, also known as bluing, is a surface treatment process in which the workpiece forms a layer of blue or black oxide film on the surface of the workpiece at room temperature or heated to an appropriate temperature in air, steam or chemical solution to improve its corrosion resistance and appearance.
