Abstract
A pilot oil source control valve block includes an accumulator and is characterized in that the accumulator is connected with a one-way valve which is also connected with an electromagnetic valve, and the one-way valve is further connected with a pressure relief valve. The accumulator is connected with the one-way valve through a reducer union which is in seal connection and equipped with a seal washer. The pilot oil source control valve block has the advantages of modularized design, convenient installation and maintenance, and high control pressure, control precision and control order, thereby fully meeting the requirements for the prior hydraulic equipment.
Description
Technical field
The utility model relates to the hydraulic control system technical field, concrete relates to a kind of guide's oil sources control valve piece.
Background technique
Oil sources guide of the prior art controls general employing pilot-operated type control valve, the CN2401737Y of Chinese patent notice of authorization, name is called the patent of pilot-actuated valve, this pilot-actuated valve mainly includes valve body, part such as spool and valve gap, the spool part is by following floating plug, last floating plug, internal magnet, external magnet, needle and Sealing are formed, and the Sealing that following floating plug and center have a through hole cooperates in aggregates, are connected for the spiral shell mosquito between last floating plug and the following floating plug, having in the last floating plug can be by the through hole of needle, the front end of needle is for cooperating with the Sealing through hole and having the taper needle point that promotes the wing, and the end of needle has the internal magnet that cooperates with external magnet, and having on the needle axially can be by the passage of fluid.Though this valve is simple in structure, its pilot pressure, control accuracy, controlling grade are all very low, are difficult to satisfy the requirement of existing hydraulic equipment.
