Description

Hydraulic steel pipe installation system

Technical field

The invention relates to a hydraulic steel pipe road installation system, which can be cold drawn pipes of stainless steel or carbon steel as required.

Background technique

At present, compared with hydraulic hoses, steel pipes have a strong and firm structure. Under the same pressure, their wall thickness is thin, the structure is simple, and they are durable.

The tube type is adjacent to the easy hydraulic system suitable for small flow. The benefits are: easy access means, easy structure, and unobstructed oil passages between valves in the system. Its weaknesses are: component evacuation facilities, which occupy a large space, intertwined pipelines, and many joints, which are not convenient for loading, unloading and repairing. The adjacent plate type is suitable for any hydraulic system, and its benefits are: easy replacement of components and simplified pipelines. The adjacent body material associated with the plate valve has two states: adjacent plate and manifold block. The structure of the adjacent plate is easy, and it is easy to verify the oil circuit, but there are many oil pipes on the plate, the installation is extremely laborious, and the space is large. The integrated block has a compact structure and a small footprint, which is convenient for loading, unloading and repairing. It can simplify the attempt of the hydraulic system to the selection of the integrated block group, thus gaining popular use. However, it also has weaknesses in material attempts such as heavy workload, messy processing, and inadequate arbitrarily correcting the system.
