Abstract
The invention discloses an operating valve shell, comprising a shell, wherein the shell is internally provided with a working cavity; the side wall of the working cavity is provided with a through hole communicated with the working cavity; the top of the shell is provided with a connection shaft; the side wall of the connection shaft is provided with a limit notch; the side wall of the working cavity is further provided with a spline groove; the bottom of the shell is provided with a connection flange; and the top surface of the connection shaft is provided with a limit hole. The operating valve shell is simple and compact in structure and is effective and accurate in control.
Description
Technical field
The present invention relates to a kind of rock drill equipment, specifically is a kind of control valve shell.
Background technique
In hydraulic pressure and hydraudynamic drive technology, control valve is exactly operating valve or is control valve, and directional control valve is arranged, pressure valve, Flow valve or the like.Handling is exactly through hydraulic pressure or hydraudynamic drive, makes these valve events, thereby reaches the purpose of control direction (switching-over), pressure or flow, and these valves have manual, also have automatically.
To various structure, there is the control inaccuracy in the unreasonable structure of control valve in the existing technology.
Summary of the invention
It is a kind of simple in structure, compact that the present invention provides, effectively accurately the control valve shell that is used for rock drill of control.
Technical solution problem of the present invention provides following scheme:
A kind of control valve shell; Comprise housing; It is characterized in that: said enclosure interior has active chamber, and the sidewall of said active chamber is provided with the through hole of UNICOM's active chamber, and the top of said housing is provided with coupling shaft; The sidewall of said coupling shaft is provided with spacing breach, has spline on the sidewall of said active chamber.
The bottom of said housing has adpting flange, and the end face of said coupling shaft is provided with spacing hole.
The present invention is provided with control hole on the sidewall of active chamber, have coupling shaft through the top of regulating active chamber and effectively avoid controlling the normal operation that inaccuracy causes influencing machinery equipment.
Description of drawings
Fig. 1 is a structural representation of the present invention.
