Abstract
The invention belongs to the technical field of hydraulic pressure regulating devices, and particularly relates to a hydraulic cylinder with stable connection. The invention provides a hydraulic cylinder with high safety performance, small operating noise and stable connection, which comprises two mutually-independent cylinders and a connector, wherein the cylinders are connected by the connector, and the cylinders are in flange connection with the connector; a flange is arranged on each cylinder; the connector is in flange connection with the cylinders by the flanges; and the flanges are made of stainless steel and are welded on the cylinders. The hydraulic cylinder has the advantages of small connection gap, high sealing performance, stable connection, high safety performance, low noise during operation and long service life, and is difficult to loose in the operating process.
Description
Technical field
The invention belongs to fluid power regulator technical field, be specifically related to a kind of firm fluid power cylinder that connects.
Background technique
The critical piece of fluid power regulator is the fluid power cylinder, two cylinder barrels independent of each other about existing fluid power cylinder generally is divided into, and two cylinder barrels connect by a connecting body.The left and right sides cylinder barrel of existing fluid power cylinder adopts the mode of cutting ferrule to be connected with connecting body mostly, but the connection of this FERRULETYPE built on the sand, takes place easily to become flexible poor safety performance in fluid power cylinder working process; The seam crack is big, poor sealing performance; And fluid power cylinder noise when work is very big.
Summary of the invention
In order to solve deficiency of the prior art, it is good to the purpose of this invention is to provide a kind of Safety performance, and operating noise is little, connects firm fluid power cylinder.
For achieving the above object, the technical solution used in the present invention is a kind of firm fluid power cylinder that connects, and comprises two cylinder barrels independent of each other and a connecting body, and described cylinder barrel connects by connecting body, and the flange-type that is connected between cylinder barrel and the connecting body connects.
Described cylinder barrel is provided with flange plate, and described connecting body realizes that by described flange plate and cylinder barrel flange is connected.
Described flange plate is the steel flange dish, and described steel flange dish is welded on the cylinder barrel.
Described flange plate comprises a flanged surface, and the seam face of described flange plate is provided with seal groove, is provided with O-ring seal in the described seal groove.
Compared with prior art, beneficial effect of the present invention shows as: it is little to connect the slit, good seal performance; Connect firmly, be difficult for taking place to become flexible the Safety performance height in fluid power cylinder working process; Fluid power cylinder noise when work is very little, the long service life of fluid power cylinder.
Description of drawings
