Problems solved by technology

Although this design has the functions of throttling adjustment and decompression balance, there are defects in the use effect, that is, the throttling structure is only a simple flow control, and the decompression structure is also a simple pressure treatment. When the actuator needs more precise control, this design Can not better achieve the purpose of use

Abstract

The invention discloses a balance speed regulating integrated valve which comprises a valve body, a speed change valve assembly and a balance valve assembly, wherein the speed change valve assembly comprises a speed change valve core; a self-regulating spring is matched at one end surface of the speed change valve core; the other end of the self-regulating spring is hermetically assembled with anupper valve hole port through a screw plug; a remote control port is arranged at the other end of the upper valve hole and communicated with the other end surface of the speed change valve core; and the balance valve assembly comprises a balance valve core and is provided with an oil inlet and an oil outlet. One valve body is arranged for integrating the valve cores with two functions simultaneously, and the overall structure is compact and small in volume; return springs are arranged at two ends of the balance valve core, after oil pressure at the two ends are canceled, the return springs can automatically reset, the structure is reasonable, and the operation is convenient; different output interfaces which have convenient connection, convenient loading and strong integrated operation are arranged simultaneously on the valve body; and joint bodies which have convenient disassembly and easy replacement are independently arranged and improve the service life of components.

Description

technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to a balanced speed regulating integrated valve. Background technique [0002] General balance or variable speed valves are mostly independently designed, but there are also hydraulic valve structures that integrate these two functions, such as the Chinese invention patent "A Speed ​​Control Valve" (Notice No. ZL200720070319.7) CN201047365Y) is exactly this type of design; it includes a valve body, a decompression mechanism and a throttling mechanism arranged inside the valve body, and it is characterized in that the inside of the valve body has a main hole with an upward opening, and there is an oil inlet below the valve body The oil inlet hole is connected to the upper end of the main hole through a casting channel inside the valve body, and the lower end of the main hole has a small damping hole connected with the oil inlet hole, and the oil outlet hole passes through a ...
